Android webView截圖顯示在imageView上

Picture picture = webView.capturePicture();

int weight = picture.getWidth(); 
int height = picture.getHeight(); 
if (weight > 0 && height > 0){
        Bitmap bitmap = Bitmap.createBitmap(weight, height,
        Bitmap.Config.ARGB_8888);
 Canvas canvas = new Canvas(bitmap);
 picture.draw(canvas);
 mImageView.setImageBitmap(bitmap); 
}

也可以任意的對bitmap作影像處裡達到需要的效果
