也许您已经找到了解决方案,但为了以防万一,我认为这就是您所需要的:

Bitmap src = BitmapFactory.decodeResource(this.getResources(), drawable.sample);
int width = src.getWidth();
int height = src.getHeight();
float skewX = 5.0;
float skewY = 6.0;
Matrix matrix = new Matrix();
matrix.setSkew(skewX, skewY);
Bitmap img = Bitmap.createBitmap(src, 0, 0, width, height, matrix, true);

这可以帮助你

Bitmap bitmapOrg = BitmapFactory.decodeResource(getResources(),                     R.drawable.flower_blue);

        Bitmap croppedBmp = Bitmap.createBitmap(bitmapOrg, 0, 0,
                bitmapOrg.getWidth() / 2, bitmapOrg.getHeight());
        int h = bitmapOrg.getHeight();
        canvas.drawBitmap(bitmapOrg, 10, 10, paint);
        canvas.drawBitmap(croppedBmp, 10, 10 + h + 10, paint);
