28 | cfg.r = 8; 29 | cfg.g = 8; 30 | cfg.b = 8; 31 | cfg.a = 8; 32 | DeviceCameraControl cameraControl = new AndroidDeviceCameraController(this); 33 | initialize(new MyGdxGame0606(cameraControl), cfg); 34 | ``` 35 | 36 | 你可以点击进入AndroidApplicationConfiguration去看看r,g,b,a原来数值如下 37 | 38 | ```java 39 | /** number of bits per color channel **/ 40 | public int r = 5, g = 6, b = 5, a = 0; 41 | ``` 42 | 43 | rgba的具体值指的是每种颜色的比特位数，这里改为8位，大概的意思就是每种颜色深度为8位，也就是2的8次幂，也就是256，和photoshop中意义一样。这么设置的原因是为了libGDX中的画布的后边能够正常的显示android的摄像头，不然颜色和在android上调用摄像头有出入，色彩不会同样的丰富。 44 | 45 | 同样在AndroidLauncher.class中，将OpenGL surface 模式设置成TRANSLUCENT 46 | 47 | 48 | ```java 49 | if (graphics.getView() instanceof SurfaceView) { 50 | SurfaceView glView = (SurfaceView) graphics.getView(); 51 | // force alpha channel - I'm not sure we need this as the GL surface 52 | // is already using alpha channel 53 | glView.getHolder().setFormat(PixelFormat.TRANSLUCENT); 54 | } 55 | ``` 56 | 57 | 然后是，在AndroidLauncher.class新建一个post方法，用来帮助唤起一些异步线程 58 | 59 | ```java 60 | public void post(Runnable r) { 61 | handler.post(r); 62 | } 63 | ``` 64 | 65 | 以上就是AndroidLauncher.class所要完成的全部内容。 66 | **如何让屏幕透明** 67 | 68 | 很简单，在core项目中MyGdxGame0606.class主类中的render()渲染方法中，要注意使用glClearColor()清屏时，参数的选择必须全部是0，这样相机预览的画面才会显示在render画面的后边 69 | 70 | ```java 71 | Gdx.gl20.glClearColor(0f, 0.0f, 0.0f, 0.0f); 72 | ``` 73 | 74 | **清屏准备完毕，现在就是要调用android摄像头的时候到了** 75 | 76 | 首先了解一下，把大象装冰箱中总共分几步？对于调用android摄像头的步骤则可以分如下几部？Android相机有特别的工作顺序必须遵守，通过application的callbacks回调函数能管理相机的状态，机器的工作状态将由AndroidDeviceCameraController.class进行管理（desktop没有实现，Android已实现）。 77 | 相机的工作状态一次是 Ready -> Preview -> autoFocusing -> ShutterCalled -> Raw PictureData -> Postview PictureData -> Jpeg PictureData -> Ready （可以做一个表格） 78 | 本实例代码实现的顺序也可以概括为 Ready -> Preview -> autoFocusing -> Jpeg PictureData -> Ready 79 | **新建AndroidDeviceCameraController** 80 | 81 | 在core项目中，新建一个DeviceCameraController类,而为了配合core中DeviceCameraControl，在android项目中，新建一个AndroidDeviceCameraController 类，来控制设备的摄像头，它要继承DeviceCameraControl，同时还要实现Camera.PictureCallback：(android.hardware.Camera.PictureCallback)Camera.AutoFocusCallback(android.hardware.Camera.AutoFocusCallback)，共计三个接口，来实现android摄像头从准备到拍摄的过程。 82 | 83 | ```java 84 | public class AndroidDeviceCameraController implements DeviceCameraControl, Camera.PictureCallback, Camera.AutoFocusCallback { 85 | } 86 | ``` 87 | AndroidDeviceCameraController 新建后，逐步实现摄像头该有的各个功能。 88 | **1.准备显示预览信息的CameraSurface** 89 | 90 | 我们产生一个CameraSurface类来负责管理摄像头和它收集的图像，这里我和android摄像相关的代码一致 91 | 92 | ```java 93 | public class CameraSurface extends SurfaceView implements SurfaceHolder.Callback { 94 | private Camera camera; 95 | public CameraSurface( Context context ) { 96 | super( context ); 97 | // We're implementing the Callback interface and want to get notified 98 | // about certain surface events. 99 | getHolder().addCallback( this ); 100 | // We're changing the surface to a PUSH surface, meaning we're receiving 101 | // all buffer data from another component - the camera, in this case. 102 | getHolder().setType( SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS ); 103 | } 104 | public void surfaceCreated( SurfaceHolder holder ) { 105 | // Once the surface is created, simply open a handle to the camera hardware. 106 | camera = Camera.open(); 107 | } 108 | public void surfaceChanged( SurfaceHolder holder, int format, int width, int height ) { 109 | // This method is called when the surface changes, e.g. when it's size is set. 110 | // We use the opportunity to initialize the camera preview display dimensions. 111 | Camera.Parameters p = camera.getParameters(); 112 | p.setPreviewSize( width, height ); 113 | camera.setParameters( p ); 114 | // We also assign the preview display to this surface... 115 | try { 116 | camera.setPreviewDisplay( holder ); 117 | } catch( IOException e ) { 118 | e.printStackTrace(); 119 | } 120 | } 121 | public void surfaceDestroyed( SurfaceHolder holder ) { 122 | // Once the surface gets destroyed, we stop the preview mode and release 123 | // the whole camera since we no longer need it. 124 | camera.stopPreview(); 125 | camera.release(); 126 | camera = null; 127 | } 128 | public Camera getCamera() { 129 | return camera; 130 | } 131 | } 132 | ``` 133 | 134 | **2.在android项目中增加相机预览视图** 135 | 136 | 在android项目的AndroidDeviceController类，使用activity.addContentView，直接将cameraSurface显示在android设备的屏幕上 137 | 138 | ```java 139 | @Override 140 | public void prepareCamera() { 141 | if (cameraSurface == null) { 142 | cameraSurface = new CameraSurface(activity); 143 | } 144 | activity.addContentView( cameraSurface, new LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT ) ); 145 | } 146 | ``` 147 | 148 | ```java 149 | @Override 150 | public synchronized void prepareCamera() { 151 | if (cameraSurface == null) { 152 | cameraSurface = new CameraSurface(activity); 153 | } 154 | FrameLayout.LayoutParams params = new FrameLayout.LayoutParams (680,680); 155 | params.rightMargin=150;//可以通过设置rightMargin控制组件的实际位置 156 | params.leftMargin=200;//可以通过设置rightMargin控制组件的实际位置 157 | params.topMargin=100; 158 | activity.addContentView(cameraSurface, params); 159 | 160 | 161 | } 162 | ``` 163 | 164 | prepareCamera方法应该在libgdx渲染过程中异步调用 165 | 166 | ```java 167 | @Override 168 | public void prepareCameraAsync() { 169 | Runnable r = new Runnable() { 170 | public void run() { 171 | prepareCamera(); 172 | } 173 | }; 174 | activity.post(r); 175 | } 176 | 177 | @Override 178 | public void prepareCameraAsync() { 179 | Runnable r = new Runnable() { 180 | public void run() { 181 | prepareCamera(); 182 | } 183 | }; 184 | activity.post(r); 185 | } 186 | ``` 187 | 188 | 当CameraSurface和camera 对象准备好了的时候（通过检测cameraSurface!=null && cameraSurface.getCamera() != null），就可以让相机由准备状态进入预览模式 189 | 190 | ```java 191 | @Override 192 | public boolean isReady() { 193 | if (cameraSurface!=null && cameraSurface.getCamera() != null) { 194 | return true; 195 | } 196 | return false; 197 | } 198 | ``` 199 | 200 | ```java 201 | @Override 202 | public boolean isReady() { 203 | if (cameraSurface != null && cameraSurface.getCamera() != null) { 204 | return true; 205 | } 206 | return false; 207 | } 208 | ``` 209 | 210 | 异步调用开启预览 211 | 212 | ```java 213 | @Override 214 | public synchronized void startPreviewAsync() { 215 | Runnable r = new Runnable() { 216 | public void run() { 217 | startPreview(); 218 | } 219 | }; 220 | activity.post(r); 221 | } 222 | @Override 223 | public synchronized void startPreview() { 224 | // ...and start previewing. From now on, the camera keeps pushing preview 225 | // images to the surface. 226 | if (cameraSurface != null && cameraSurface.getCamera() != null) { 227 | cameraSurface.getCamera().startPreview(); 228 | } 229 | } 230 | ``` 231 | 232 | **3.由预览模式进行拍照** 233 | 234 | 拍照前还要AndroidDeviceCameraController类设置下相机合适的参数 235 | 236 | 237 | ```java 238 | public void setCameraParametersForPicture(Camera camera) { 239 | // Before we take the picture - we make sure all camera parameters are as we like them 240 | // Use max resolution and auto focus 241 | Camera.Parameters p = camera.getParameters(); 242 | List supportedSizes = p.getSupportedPictureSizes(); 243 | int maxSupportedWidth = -1; 244 | int maxSupportedHeight = -1; 245 | for (Camera.Size size : supportedSizes) { 246 | if (size.width > maxSupportedWidth) { 247 | maxSupportedWidth = size.width; 248 | maxSupportedHeight = size.height; 249 | } 250 | } 251 | p.setPictureSize(maxSupportedWidth, maxSupportedHeight); 252 | p.setFocusMode(Camera.Parameters.FOCUS_MODE_AUTO); 253 | camera.setParameters( p ); 254 | } 255 | ``` 256 | 257 | 接下来，我们将通过设置相机的参数，设置聚焦为自动模式， 258 | 259 | ```java 260 | @Override 261 | public synchronized void takePicture() { 262 | // the user request to take a picture - start the process by requesting focus 263 | setCameraParametersForPicture(cameraSurface.getCamera()); 264 | cameraSurface.getCamera().autoFocus(this); 265 | } 266 | ``` 267 | 268 | 当聚焦完成后，我们就要拍照了，仅仅实现JPG回调实现 269 | 270 | 271 | ```java 272 | @Override 273 | public synchronized void onAutoFocus(boolean success, Camera camera) { 274 | // Focus process finished, we now have focus (or not) 275 | if (success) { 276 | if (camera != null) { 277 | camera.stopPreview(); 278 | // We now have focus take the actual picture 279 | camera.takePicture(null, null, null, this); 280 | } 281 | } 282 | } 283 | @Override 284 | public synchronized void onPictureTaken(byte[] pictureData, Camera camera) { 285 | this.pictureData = pictureData; 286 | } 287 | 288 | @Override 289 | public synchronized void onAutoFocus(boolean success, Camera camera) { 290 | // Focus process finished, we now have focus (or not) 291 | if (success) { 292 | if (camera != null) { 293 | camera.stopPreview(); 294 | /*增加三个回调函数shutterCallback, rawPictureCallback, jpegPictureCallback后，可以进行拍照，并且成功保存*/ 295 | // We now have focus take the actual picture 296 | camera.takePicture(shutterCallback, rawPictureCallback, jpegPictureCallback);//54wall 297 | camera.startPreview(); 298 | 299 | } 300 | } 301 | } 302 | 303 | @Override 304 | public synchronized void onPictureTaken(byte[] pictureData, Camera camera) { 305 | // We got the picture data - keep it 306 | this.pictureData = pictureData; 307 | } 308 | 309 | ShutterCallback shutterCallback = new ShutterCallback() { 310 | @Override 311 | public void onShutter() { 312 | } 313 | }; 314 | 315 | PictureCallback rawPictureCallback = new PictureCallback() { 316 | @Override 317 | public void onPictureTaken(byte[] arg0, Camera arg1) { 318 | 319 | } 320 | }; 321 | 322 | PictureCallback jpegPictureCallback = new PictureCallback() { 323 | @Override 324 | public void onPictureTaken(byte[] arg0, Camera arg1) { 325 | /*可以在Android项目中中生成图片*/ 326 | // String fileName = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) 327 | // .toString() 328 | // + File.separator 329 | // + "PicTest_" + System.currentTimeMillis() + ".jpg"; 330 | // File file = new File(fileName); 331 | // if (!file.getParentFile().exists()) { 332 | // file.getParentFile().mkdir(); 333 | // } 334 | // 335 | // try { 336 | // BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file)); 337 | // bos.write(arg0); 338 | // bos.flush(); 339 | // bos.close(); 340 | // 341 | // } catch (Exception e) { 342 | // 343 | // } 344 | pictureData=arg0; 345 | 346 | }; 347 | }; 348 | ``` 349 | 以上就是拍照的具体步骤，之后照片完成后，需要将图像数据进行保存到存储器上 350 | 拍照的具体功能实现了，为了在libgdx中能够看到摄像头，当然需要在实现ApplicationListener的主类的render（）进行设置了，我这里设置了三个按钮，功能分别是开启相机，进行拍摄，和一个控制人物移动的按钮（算是证明是在libgdx框架内部的）。 351 | 原代码时触控进入相机预览，松开则进行拍照，我开始还没太理解，render中因为涉及到相机的功能切换，所以在libgdx主类中定义了相机的这几种状态 352 | ```java 353 | public enum Mode { 354 | normal, prepare, preview, takePicture, waitForPictureReady, 355 | }， 356 | ``` 357 | render（）中的代码非常长，不过就是在相机的各个状态中切换，具体代码如下： 358 | ```java 359 | @Override 360 | public void render() { 361 | // Gdx.gl20.glClearColor(0.0f, 0f, 0.0f, 0.0f);//黑 362 | // Gdx.gl.glClearColor(1, 1, 1, 1);//背景为白色 363 | Gdx.gl.glClearColor(0.57f, 0.40f, 0.55f, 1.0f);// 紫色 364 | Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);// 清屏 365 | render_preview(); 366 | 367 | } 368 | 369 | 370 | public void render_preview() { 371 | /* 我已经将preview变为takePicture状态移动到click中，实现先预览再拍照，这样便于理解相机的运行步骤 */ 372 | Gdx.gl20.glHint(GL20.GL_GENERATE_MIPMAP_HINT, GL20.GL_NICEST); 373 | if (mode == Mode.takePicture) { 374 | Gdx.gl20.glClearColor(0f, 0.0f, 0.0f, 0.0f); 375 | if (deviceCameraControl != null) { 376 | deviceCameraControl.takePicture(); 377 | } 378 | mode = Mode.waitForPictureReady; 379 | } else if (mode == Mode.waitForPictureReady) { 380 | Gdx.gl20.glClearColor(0.0f, 0f, 0.0f, 0.0f); 381 | } else if (mode == Mode.prepare) { 382 | Gdx.gl20.glClearColor(0.0f, 0.0f, 0f, 0.6f); 383 | if (deviceCameraControl != null) { 384 | if (deviceCameraControl.isReady()) { 385 | deviceCameraControl.startPreviewAsync(); 386 | mode = Mode.preview; 387 | } 388 | } 389 | } else if (mode == Mode.preview) { 390 | Gdx.gl20.glClearColor(0.0f, 0.0f, 0.0f, 0f); 391 | } else { 392 | /* mode = normal */ 393 | Gdx.gl20.glClearColor(0.0f, 0.0f, 0.6f, 1.0f); 394 | 395 | } 396 | Gdx.gl20.glClear(GL20.GL_COLOR_BUFFER_BIT | GL20.GL_DEPTH_BUFFER_BIT); 397 | /* 下边放到texture.bind();时效果一致 */ 398 | batch.begin(); 399 | stage.act(); // 更新舞台逻辑 400 | batch.draw(texture, 0, 0, 3f*texture.getWidth(), 3f*texture.getHeight());

450 | //保存混合之后的相片 451 | FileHandle jpgfile = Gdx.files 452 | .external("a_SDK_fail/libGdxSnapshot" + "_" + date 453 | + ".jpg"); 454 | Gdx.app.log("FileHandle", date); 455 | time_1 = System.currentTimeMillis(); 456 | deviceCameraControl.saveAsJpeg(jpgfile, cameraPixmap); 457 | time_2 = System.currentTimeMillis(); 458 | //可以得到35830ms=35s，所以非常忙，导致Mode非常缓慢的回到Mode.normal 459 | Gdx.app.log("cost", String.valueOf(time_2 - time_1));

468 | } 469 | ``` 470 | **如何实现libgdx端的截图** 471 | 472 | 因为AndroidDeviceCameraController 实现两个接口: Camera.PictureCallback，所以可以直接调用，而deviceCameraControl.getPictureData()的byte[]数据则来自AndroidDeviceCameraController,如下 473 | ```java 474 | @Override 475 | public synchronized byte[] getPictureData() { 476 | // Give to picture data to whom ever requested it 477 | return pictureData; 478 | } 479 | if (deviceCameraControl.getPictureData() != null) { // camera picture was actually taken 480 | Pixmap cameraPixmap = new Pixmap(deviceCameraControl.getPictureData(), 0, deviceCameraControl.getPictureData().length); 481 | } 482 | ``` 483 | 484 | 下面是截图的具体操作过程是保存为pixmap，libgdx中保存格式都是pixmap，而非android中的bitmap 485 | 486 | ```java 487 | public Pixmap getScreenshot(int x, int y, int w, int h, boolean flipY) { 488 | Gdx.gl.glPixelStorei(GL10.GL_PACK_ALIGNMENT, 1); 489 | final Pixmap pixmap = new Pixmap(w, h, Format.RGBA8888); 490 | ByteBuffer pixels = pixmap.getPixels(); 491 | Gdx.gl.glReadPixels(x, y, w, h, GL10.GL_RGBA, GL10.GL_UNSIGNED_BYTE, pixels); 492 | final int numBytes = w * h * 4; 493 | byte[] lines = new byte[numBytes]; 494 | if (flipY) { 495 | final int numBytesPerLine = w * 4; 496 | for (int i = 0; i < h; i++) { 497 | pixels.position((h - i - 1) * numBytesPerLine); 498 | pixels.get(lines, i * numBytesPerLine, numBytesPerLine); 499 | } 500 | pixels.clear(); 501 | pixels.put(lines); 502 | } else { 503 | pixels.clear(); 504 | pixels.get(lines); 505 | } 506 | return pixmap; 507 | } 508 | ``` 509 | 510 | 接下来的操作都是需要消耗大量时间和CPU资源的，首先不应放到UI线程中，应该新开线程去执行，并且最好加一个进度条，在代码示例中，我们并没有那么做，所以屏幕在这个过程中会出现卡死的状况。我这里则直接保存了三分文件，分别是截图，android摄像头的拍摄相片，还有二者混合之后的图片，代码如下 511 | 512 | 513 | ```java 514 | /* 仅保存screenshot，对同一时间的图片进行保存然后进行比较 */ 515 | Pixmap screenshotPixmap_test = getScreenshot(0, 0, 516 | Gdx.graphics.getWidth(), Gdx.graphics.getHeight(), true); 517 | FileHandle jpgfile_screenshot = Gdx.files 518 | .external("a_SDK_fail/libGdxSnapshot" + "_" + date 519 | + "_screenshot.jpg"); 520 | deviceCameraControl.saveAsJpeg(jpgfile_screenshot, 521 | screenshotPixmap_test); 522 | /* 仅保存cameraPixma，对同一时间的图片进行保存然后进行比较 */ 523 | Pixmap cameraPixmap_test = new Pixmap( 524 | deviceCameraControl.getPictureData(), 0, 525 | deviceCameraControl.getPictureData().length); 526 | FileHandle jpgfile_cameraPixmap = Gdx.files 527 | .external("a_SDK_fail/libGdxSnapshot" + "_" + date 528 | + "_camera.jpg"); 529 | deviceCameraControl.saveAsJpeg(jpgfile_cameraPixmap, 530 | cameraPixmap_test); 531 | /* 保存混合之后的相片 */ 532 | FileHandle jpgfile = Gdx.files 533 | .external("a_SDK_fail/libGdxSnapshot" + "_" + date 534 | + ".jpg"); 535 | Gdx.app.log("FileHandle", date); 536 | time_1 = System.currentTimeMillis(); 537 | deviceCameraControl.saveAsJpeg(jpgfile, cameraPixmap); 538 | time_2 = System.currentTimeMillis(); 539 | /* 可以得到35830ms=35s，所以非常忙，导致Mode非常缓慢的回到Mode.normal */ 540 | Gdx.app.log("cost", String.valueOf(time_2 - time_1)); 541 | deviceCameraControl.stopPreviewAsync(); 542 | ``` 543 | **混合两个pixmap** 544 | 545 | 接下来是整合两个PIxmap对象，LibGDX Pixmap对象可以帮助我们实现这个功能，但是因为相机的相片可能有不同的aspect ratio，所以我们也需要分别对待处理 546 | 547 | ```java 548 | private void merge2Pixmaps(Pixmap mainPixmap, Pixmap overlayedPixmap) { 549 | // merge to data and Gdx screen shot - but fix Aspect Ratio issues between the screen and the camera 550 | Pixmap.setFilter(Filter.BiLinear); 551 | float mainPixmapAR = (float)mainPixmap.getWidth() / mainPixmap.getHeight(); 552 | float overlayedPixmapAR = (float)overlayedPixmap.getWidth() / overlayedPixmap.getHeight(); 553 | if (overlayedPixmapAR < mainPixmapAR) { 554 | int overlayNewWidth = (int)(((float)mainPixmap.getHeight() / overlayedPixmap.getHeight()) * overlayedPixmap.getWidth()); 555 | int overlayStartX = (mainPixmap.getWidth() - overlayNewWidth)/2; 556 | mainPixmap.drawPixmap(overlayedPixmap, 557 | 0, 558 | 0, 559 | overlayedPixmap.getWidth(), 560 | overlayedPixmap.getHeight(), 561 | overlayStartX, 562 | 0, 563 | overlayNewWidth, 564 | mainPixmap.getHeight()); 565 | } else { 566 | int overlayNewHeight = (int)(((float)mainPixmap.getWidth() / overlayedPixmap.getWidth()) * overlayedPixmap.getHeight()); 567 | int overlayStartY = (mainPixmap.getHeight() - overlayNewHeight)/2; 568 | mainPixmap.drawPixmap(overlayedPixmap, 569 | 0, 570 | 0, 571 | overlayedPixmap.getWidth(), 572 | overlayedPixmap.getHeight(), 573 | 0, 574 | overlayStartY, 575 | mainPixmap.getWidth(), 576 | overlayNewHeight); 577 | } 578 | } 579 | ``` 580 | **将图片保存为jpg** 581 | 582 | 所以我们选择JPG格式进行保存，一种方式就是使用Android的bitmap类对图片进行jpg格式的保存，这个功能可以在AndroidDeviceController类中实现，因为它是Android特有的功能，所以我们想不用它。 583 | 尽量将大部分代码全部放到libgdx框架中，就是大部分实现的代码要在core中，然而libgdx的pixel格式是RGBA，而bitmap的Pixmap格式是ARGB，所以我们需要一bit一bit的将颜色转换过来 584 | 585 | 586 | ```java 587 | @Override 588 | public void saveAsJpeg(FileHandle jpgfile, Pixmap pixmap) { 589 | FileOutputStream fos; 590 | int x=0,y=0; 591 | int xl=0,yl=0; 592 | try { 593 | Bitmap bmp = Bitmap.createBitmap(pixmap.getWidth(), pixmap.getHeight(), Bitmap.Config.ARGB_8888); 594 | // we need to switch between LibGDX RGBA format to Android ARGB format 595 | for (x=0,xl=pixmap.getWidth(); x ARGB 599 | int RGB = color >> 8; 600 | int A = (color & 0x000000ff) << 24; 601 | int ARGB = A | RGB; 602 | bmp.setPixel(x, y, ARGB); 603 | } 604 | } 605 | // Finished Color format conversion 606 | fos = new FileOutputStream(jpgfile.file()); 607 | bmp.compress(CompressFormat.JPEG, 90, fos); 608 | // Finished Comression to JPEG file 609 | fos.close(); 610 | } catch (FileNotFoundException e) { 611 | e.printStackTrace(); 612 | } catch (IOException e) { 613 | e.printStackTrace(); 614 | } catch (IllegalArgumentException e) { 615 | e.printStackTrace(); 616 | } 617 | } 618 | ``` 619 | **停止预览** 620 | 621 | 在完成保存图片后，我们将停止预览窗口，并且从Activity窗口中移去CameraSurface，我们同样也将停止camera继续想camera surface继续发送preview，我们同样异步执行这些。 622 | 623 | 624 | ```java 625 | @Override 626 | public synchronized void stopPreviewAsync() { 627 | Runnable r = new Runnable() { 628 | public void run() { 629 | stopPreview(); 630 | } 631 | }; 632 | activity.post(r); 633 | } 634 | @Override 635 | public synchronized void stopPreview() { 636 | // stop previewing. 637 | if (cameraSurface != null) { 638 | if (cameraSurface.getCamera() != null) { 639 | cameraSurface.getCamera().stopPreview(); 640 | } 641 | ViewParent parentView = cameraSurface.getParent(); 642 | if (parentView instanceof ViewGroup) { 643 | ViewGroup viewGroup = (ViewGroup) parentView; 644 | viewGroup.removeView(cameraSurface); 645 | } 646 | } 647 | } 648 | ``` 649 | 650 | 注意在合成两张pixmap也就是混合相机取景和libgdx截图时分辨率有差异。在我们的Pixmaps整合过程中依然还存在一个问题，就是相机的分辨率和我们的截图分辨率也许是不同的（我在我的三星手机上，我把一个480x320屏幕截图延伸到2560x1920 大小的图片）。一个围绕它的解决方法就是扩大Libgdx视图的尺寸到更大，比实际物理设备的尺寸要大，要实现他需要使用setFixedSize()功能。真实的屏幕尺寸是根据BPU内存。 651 | 然而，在这个时间中我设法去设置虚拟屏幕尺寸为960x640（可能因为GPU显存已经被origin的带下分配了） 652 | 653 | 654 | ```java 655 | public void setFixedSize(int width, int height) { 656 | if (graphics.getView() instanceof SurfaceView) { 657 | SurfaceView glView = (SurfaceView) graphics.getView(); 658 | glView.getHolder().setFixedSize(width, height); 659 | glView.getHolder().setFormat(PixelFormat.TRANSLUCENT); 660 | } 661 | } 662 | public void restoreFixedSize() { 663 | if (graphics.getView() instanceof SurfaceView) { 664 | SurfaceView glView = (SurfaceView) graphics.getView(); 665 | glView.getHolder().setFixedSize(origWidth, origHeight); 666 | glView.getHolder().setFormat(PixelFormat.TRANSLUCENT); 667 | } 668 | } 669 | ``` 670 | **一些小提示** 671 | 672 | 1. 提示1 673 | 注意，代码仅仅适用于Android平台，并非跨平台解决方法，但是我觉得至少在桌面端，应该可以提供类似功能的代码 674 | 2. 提示2 675 | 在整合图片，并将图片数据保存到存储器上时，会花大量的时间，是因为libgdx颜色方案是RGBA而bitmap颜色方案是ARGB 676 | 3. 提示3 677 | 最后需要注意的 678 | 我仅仅测试了一部分Android设备，不同的GPU会产生不同的现象。 679 | **完整代码已上传github** 680 | [https://github.com/54wall/LibgdxAndroidCamera](https://github.com/54wall/LibgdxAndroidCamera) 681 | 最后的截图，按下camera可以开启相机，看下shot，就是进行拍摄，move可以控制猫向右侧移动 682 | 683 | ![](https://github.com/54wall/LibgdxAndroidCamera/blob/master/readme_img/4.jpg) 684 | --------------------------------------------------------------------------------
