 1 | # content2picture
 2 | 先看需求：  当内容已经超出了手机可显示的范围时，要截取这些所有的内容，从而生成所谓的”长截图”.  没什么难点，利用了webview的特点，和scrollview 的view的绘制，生成bitmap。
 3 | 
 4 | 主要代码：
 5 | 
 6 | //这是scrollview的
 7 | 
 8 | public static Bitmap getBitmapByView(ScrollView scrollView) {
 9 |         int h = 0;
10 |         Bitmap bitmap = null;
11 | 
12 |         for (int i = 0; i < scrollView.getChildCount(); i++) {
13 |             h += scrollView.getChildAt(i).getHeight();
14 |             scrollView.getChildAt(i).setBackgroundColor(
15 |                     Color.parseColor("#ffffff"));
16 |         }
17 | 
18 |         bitmap = Bitmap.createBitmap(scrollView.getWidth(), h,
19 |                 Bitmap.Config.RGB_565);
20 |         final Canvas canvas = new Canvas(bitmap);
21 |         scrollView.draw(canvas);
22 |         return bitmap;
23 |     }
24 | 
25 | 
26 | /**
27 |      * mScrollView
28 |      * 
29 |      * @param context
30 |      * @param scrollView
31 |      */
32 |     public static void scrollviewContent2Png(Context context,
33 |             ScrollView scrollView) {
34 |         Bitmap bmp = null;
35 |         bmp = getBitmapByView(scrollView);
36 |         saveBitmapToCamera(context, bmp, null);
37 |     }
38 | 
39 | //这是webview的，利用了webview的api
40 | 
41 | private static Bitmap captureWebView(WebView webView) {
42 |         Picture snapShot = webView.capturePicture();
43 |         Bitmap bmp = Bitmap.createBitmap(snapShot.getWidth(),
44 |                 snapShot.getHeight(), Bitmap.Config.ARGB_8888);
45 |         Canvas canvas = new Canvas(bmp);
46 |         snapShot.draw(canvas);
47 |         return bmp;
48 |     }
49 | 
50 | 代码粗略，只实现了功能部分，在图片生成的时候，未使用线程，如果还有其他比较好的方案，可以相互交流下
