得到将view中的内容保存为图片

private Bitmap getBitmapFromView(View view) {      Bitmap bitmap = null;      try {          int width = view.getWidth();          int height = view.getHeight();          if(width != 0 && height != 0){              bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);              Canvas canvas = new Canvas(bitmap);              view.layout(0, 0, width, height);              view.draw(canvas);          }      } catch (Exception e) {          bitmap = null;          e.getStackTrace();      }      return bitmap;  }
