    </RelativeLayout>

</RelativeLayout>

问题是Listview没有滚动

我试过了：

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);
}
}

在活动类中，我在设置适配器后写了这个：

Utility.setListViewHeightBasedOnChildren(list);

但仍然列表不滚动。

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;
}
});

检查此代码

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;
    }
});
