      android:visibility="gone" /> 
    </RelativeLayout> 
</ScrollView> 
</RelativeLayout> 

问题是，列表视图不滚动

我尝试这样做：

public class Utility { 
public static void setListViewHeightBasedOnChildren(ListView listView) { 
    ListAdapter listAdapter = listView.getAdapter(); 
    if (listAdapter == null) { 
     // pre-condition 
     return; 
    } 

    int totalHeight = 0; 
    for (int i = 0; i < listAdapter.getCount(); i++) { 
     View listItem = listAdapter.getView(i, null, listView); 
     listItem.measure(0, 0); 
     totalHeight += listItem.getMeasuredHeight(); 
    } 

    ViewGroup.LayoutParams params = listView.getLayoutParams(); 
    params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1)); 
    listView.setLayoutParams(params); 
} 
}  

在活动课我写这个设置适配器后：

Utility.setListViewHeightBasedOnChildren(list); 

但仍列表不滚动。

谢谢！

Answer 1

ListView listView; 
listView.setOnTouchListener(new ListView.OnTouchListener() { 
@Override 
public boolean onTouch(View v, MotionEvent event) { 
if (event.getAction() == MotionEvent.ACTION_MOVE) 
{ 
listView.scrollBy(0, 1); 
} 
return false; 
} 
}); 

一次检查这个代码

ListView lv = (ListView)findViewById(R.id.myListView); 
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; 
    } 
}); 

如果你请接受的答案是有用的。
