我正在开发一个应用程序,我正在使用水平和垂直搜索栏,并在拇指位置显示弹出窗口。
对于水平搜索栏,情况都很好。
但是当我们将搜索栏旋转-90/270度时,弹出窗口没有显示在正确的位置(拇指上方)
问题是我们试图将Seekbar拇指绑定到垂直位置,但我正处于水平位置的束缚。
任何帮助都很明显。

Try this vertical seekbar. As you see in **setProgress(int progress)** method thumb position will update, automatically. Good luck
import android.content.Context;
import android.graphics.Canvas;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.SeekBar;
public class VerticalSeekBar extends SeekBar {
public VerticalSeekBar(Context context) {
super(context);
}
public VerticalSeekBar(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public VerticalSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
}

super.onMeasure(heightMeasureSpec, widthMeasureSpec);
setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth());

c.rotate(-90);
c.translate(-getHeight(), 0);
super.onDraw(c);

}
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN :

setProgress(getMax() - (int) (getMax() * event.getY() / getHeight()));
onSizeChanged(getWidth(), getHeight(), 0, 0);
break;
case MotionEvent.ACTION_CANCEL :
break;
}
return true;
}
@Override
public synchronized void setProgress(int progress) {
super.setProgress(progress);
