android – 像Google一样可选的圆形图像

这就是我所说的：

取消选择上面的图像,然后选择下面的图像.

我尝试复制配置文件图片1到1.

到目前为止我的工作：

loadedImage是显示的位图

使用的方法：

private Bitmap createRoundImage(Bitmap loadedImagE) {
    Bitmap circleBitmap = Bitmap.createBitmap(loadedImage.getWidth(),loadedImage.getHeight(),Bitmap.Con@L_696_5@.ARGB_8888);

    BitmapShader shader = new BitmapShader(loadedImage,Shader.TileMode.CLAMP,Shader.TileMode.CLAMp);
    Paint paint = new Paint();
    paint.setAntiAlias(true);
    paint.setShader(shader);

    Canvas c = new Canvas(circleBitmap);
    c.drawCircle(loadedImage.getWidth() / 2,loadedImage.getHeight() / 2,loadedImage.getWidth() / 2,paint);

    return circleBitmap;
}

private StateListDrawable createStateListDrawable() {
    StateListDrawable stateListDrawable = new StateListDrawable();

    OvalShape ovalShape = new OvalShape();
    ShapeDrawable shapeDrawable = new ShapeDrawable(ovalShapE);
    stateListDrawable.addState(new int[] { android.R.attr.state_pressed },shapeDrawablE);
    stateListDrawable.addState(StateSet.WILD_CARD,shapeDrawablE);

    return stateListDrawable;
}

ImageView的大小是imageSizePx,图像的大小是imageSizePx – 3.因此,这意味着背景应该与图像重叠.哪个不起作用.
