如何在ScrollView中滑动垂直SeekBar

Question

我通过覆盖onDraw方法并将其翻转90度来制作垂直SeekBar.现在我需要将它放在ScrollView中.

实际的布局结构是

<ScrollView>
  <RelativeLayout>
     ...
     <LinearLayout>
       <com.mypackage.VerticalSeekBar/>

是否可以确保ScrollView无法获取我的搜索栏的触摸事件？

试试这个 :

ListView lv = (ListView)findViewById(R.id.myListView);  // your listview inside scrollview

    lv.setOnTouchListener(new ListView.OnTouchListener() 
    {
        @Override
        public boolean onTouch(View v, MotionEvent event) 
        {
            int action = event.getAction();
            switch (action) 
            {
            case MotionEvent.ACTION_DOWN:
                // Disallow ScrollView to intercept touch events.
                v.getParent().requestDisallowInterceptTouchEvent(true);
                break;

            case MotionEvent.ACTION_UP:
                // Allow ScrollView to intercept touch events.
                v.getParent().requestDisallowInterceptTouchEvent(false);
                break;
            }

            // Handle ListView touch events.
            v.onTouchEvent(event);
            return true;
        }
    });

在上面的代码中,我在scrollview中使用了listview滚动,你可以这样做
