我正在尝试用CircularProgressView使用PorterDuff.Mode.DST_IN屏蔽图像视图这里是屏蔽的示例代码
public static Bitmap getMaskedBitmap(Resources res, int sourceResId,Bitmap mask) {
BitmapFactory.Options options = new BitmapFactory.Options();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
options.inMutable = true;
}
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap source = BitmapFactory.decodeResource(res, sourceResId, options);
Bitmap bitmap;
if (source.isMutable()) {
bitmap = source;
} else {
bitmap = source.copy(Bitmap.Config.ARGB_8888, true);
source.recycle();
}
bitmap.setHasAlpha(true);
Canvas canvas = new Canvas(bitmap);
Paint paint = new Paint();
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DST_IN));
canvas.drawBitmap(mask, 0, 0, paint);
mask.recycle();
return bitmap;
}
source image =将是一封透明的字母" C"来自像这样的抽象人
并且掩码图像应该来自CircularProgressView。我想填写透明字母" C"使用固定的白色基于点(比率为1/10),使用CircularProgressView屏蔽字母C.是否可能?
