1 | # CameraSurfaceView
2 | ## 控件介绍
3 | 主要的功能有：拍照，录像，闪光灯，定时长录像 ,前后摄像头的切换，自适应横竖屏的切换，并且支持在后台完成以上所有操作

10 |
11 | ## 使用方法
12 |
13 | ```
14 | 1.赋予程序必要的权限；
15 |
16 | 2.布局文件中添加
17 |
18 |
22 |
23 | 或者 new CameraSurfaceView(context),即可。
24 |
25 | 3.拍照：cameraSurfaceView.capture();
26 |
27 | 录像：cameraSurfaceView.startRecord();//开始录制
28 | cameraSurfaceView.stopRecord(); //结束录制
29 | //设置录制时长为10秒视频
30 | cameraSurfaceView.startRecord(10000, new MediaRecorder.OnInfoListener() {
31 | @Override
32 | public void onInfo(MediaRecorder mr, int what, int extra) {
33 | cameraSurfaceView.stopRecord();
34 | }
35 | });
36 |
37 | 闪光灯：cameraSurfaceView.switchLight(boolean open);
38 |
39 | 前后摄像头的切换：cameraSurfaceView.setDefaultCamera(boolean backCamera);
40 |
41 | 前后台切换：cameraSurfaceView.setRunBack(boolean b)
42 |
43 | 4.释放Camera:
44 | @Override
45 | protected void onDestroy() {
46 | super.onDestroy();
47 | cameraSurfaceView.closeCamera();
48 | }
49 |
50 | ```
