Question

所以我正在尝试创建一个应用小部件，并在那里显示一个看起来像圆形ImageView的个人资料图片。 通常我只使用循环ImageView库，但对于应用小部件，您无法扩展视图（因此只有vanilla ImageView）并且必须使用RemoteViews < /强>

因此，我正在尝试使用Drawable覆盖/底层来实现此效果。我从这里Display FB profile pic in circular image view in Application尝试了gusridd的解决方案，但我的个人资料图片所在的背景也是一个图像，这只是一个带有圆形图像的白色正方形:(

为此，我使用了这个： http://curious-blog.blogspot.co.il/2014/05/create-circle-bitmap-in-android.html

并致电RemoteViews的{{1}}。

我在使用RemoteView的“自定义通知”中遇到了相同的问题，然后采用以下解决方案可以解决问题。

解决方案：使用圆形裁剪的位图

public Bitmap getCroppedBitmap(Bitmap bitmap) throws Exception {
    Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(output);

    final int color = 0xff424242;
    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());

    paint.setAntiAlias(true);
    canvas.drawARGB(0, 0, 0, 0);
    paint.setColor(color);
    canvas.drawCircle(bitmap.getWidth() / 2, bitmap.getHeight() / 2, bitmap.getWidth() / 2, paint);
    paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
    canvas.drawBitmap(bitmap, rect, rect, paint);
    return output;
}

App Widget中的Android循环Imageview
