垂直和反向搜索栏 [英] Vertical and inverted SeekBar

问题描述

我一直在寻找一个垂直搜索栏的实现，发现这个：极品＆lt;实施＆GT;垂直搜索栏！

I was looking for an implementation of a vertical SeekBar and found this: Need <working> vertical SeekBar!

它工作正常。不过，我希望它是逆转，E.I分钟是在上面，max是在底部。这可能吗？我试着将它在不同程度上，但没有成功旋转。

It works fine. However I want it to be "reversed", e.i min is on top and max is at the bottom. Is this possible? I've tried to rotate it in different degrees but with no success.

刚刚在的onDraw（）稍加修改，

Just a little modification in the onDraw(),

protected void onDraw(Canvas c) {
    c.rotate(90);
    c.translate(0, -getWidth());

    super.onDraw(c);
}

和onTouchEvent（）

and onTouchEvent(),

switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
        case MotionEvent.ACTION_MOVE:
        case MotionEvent.ACTION_UP:
            int i=0;
            i=getMax() - (int) (getMax() * event.getY() / getHeight());
            setProgress(100-i);
            Log.i("Progress",getProgress()+"");
            onSizeChanged(getWidth(), getHeight(), 0, 0);
            break;

        case MotionEvent.ACTION_CANCEL:
            break;
    }
