android 屏幕任意view截屏和图片拼接

   View dView = "需要截屏的view";
   dView.setDrawingCacheEnabled(true);
   dView.buildDrawingCache();
   //获得图片bitmap
   Bitmap bitmap = Bitmap.createBitmap(dView.getDrawingCache());
   
   //本地图片转Bitmap
  Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.corp);
//根本屏幕宽度缩放图片达到与截取图片同宽度
int secreenWidth = 	getActivity().getWindowManager().getDefaultDisplay().getWidth();
 float scaleWidth = ((float) secreenWidth) / width;
// 取得想要缩放的matrix参数
   Matrix matrix = new Matrix();
   matrix.postScale(scaleWidth, scaleWidth);
	 Bitmap visiableBitmap = Bitmap.createBitmap(bmp, 0, 0,  bmp.getWidth(),
  bmp.getHeight(), matrix, true);
                
     //获取的拼接之后的图片          
   Bitmap bitmap1 = splitVertical(visiableBitmap, bitmap);
   
   		//拼接两张图片 垂直方向
     public static Bitmap splitVertical(Bitmap first, Bitmap second) {
        int width = Math.max(first.getWidth(), second.getWidth());
        int height = first.getHeight() + second.getHeight();
        Bitmap result = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(result);
        canvas.drawBitmap(first, 0, 0, null);
        canvas.drawBitmap(second, 0, first.getHeight(), null);
        return result;
    }
