Android圆形图像列表视图

我也查看了Radial和gallery,但没有在圆形(非动画)中找到真正的列表。任何帮助都将不胜感激。最后,我想我找到了一个示例: 使用CircleListView:)参考以下代码
public class RoundedImageView extends ImageView {
public RoundedImageView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public RoundedImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public RoundedImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onDraw(Canvas canvas) {
Drawable drawable = getDrawable();
if (drawable == null) {
return;
}
if (getWidth() == 0 || getHeight() == 0) {
return;
}
Bitmap b = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP
&& drawable instanceof VectorDrawable) {
((VectorDrawable) drawable).draw(canvas);
b = Bitmap.createBitmap(canvas.getWidth(), canvas.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas();
c.setBitmap(b);
drawable.draw(c);
}
else {
b = ((BitmapDrawable) drawable).getBitmap();
}
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
int w = getWidth(), h = getHeight();
Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
canvas.drawBitmap(roundBitmap, 0,0, null);
}
public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
Bitmap sbmp;
if(bmp.getWidth() != radius || bmp.getHeight() != radius)
sbmp = Bitmap.createScaledBitmap(bmp, radius, radius, false);
else
sbmp = bmp;
Bitmap output = Bitmap.createBitmap(sbmp.getWidth(),
sbmp.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final int color = 0xffa19774;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, sbmp.getWidth(), sbmp.getHeight());
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawCircle(sbmp.getWidth() / 2+0.7f, sbmp.getHeight() / 2+0.7f,
sbmp.getWidth() / 2+0.1f, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(sbmp, rect, rect, paint);
return output;
}
}
你能详细解释一下你的意思吗,即使是一张粗糙的图纸也会有帮助,因为ListView本质上是矩形的。也许你正在寻找旋转木马,你需要旋转木马吗?。使用renderscriptdrawing不是我想要的,或者你告诉我我可以绘制ListView?我需要的是一个加载了圆形图像的ListView。
