Android 判断图片是否存在透明区域

Bitmap bgBitmap = ();
int color1 = (0, 0);
int a1 = (color1);
int color2 = (() /2, () / 2);
int a2 = (color2);
if (a1 != 255 || a2 != 255) {
    (TAG, "PicSelected is transparent ");
} else {
    (TAG, "onPicSelected is not transparent ");
}

获取图片的像素点进行判断，如果目标图片不是那种均匀透明度的图片的话，可能就需要挨个像素点去遍历了
