有時美工需要弧形背景
Screenshot_2019-10-25-17-57-20-805_com.qingmo.matchgo.png
代碼如下:
public class ArcImageView extends AppCompatImageView {
/*
*弧形高度
*/
private int mArcHeight=100;
public ArcImageView(Context context) {
this(context, null);
}
public ArcImageView(Context context, @Nullable AttributeSet attrs) {
this(context, attrs, 0);
}
@Override
protected void onDraw(Canvas canvas) {
Path path = new Path();
path.moveTo(0, 0);
path.lineTo(0, getHeight()-mArcHeight);
path.quadTo(getWidth() / 2, getHeight()+mArcHeight, getWidth(), getHeight() - mArcHeight);
path.lineTo(getWidth(), 0);
path.close();
canvas.clipPath(path);
super.onDraw(canvas);
}
}
