滾動兩個listview android

Question

我使用了兩個listview。它正確顯示，但第二個列表視圖在橫向模式下不可見。我無法在listview中使用scrollview。

我的佈局文件：

</RelativeLayout> 

我想利用這兩個列表視圖在一個單一的滾動。怎麼做？有什麼建議嗎？

感謝，

You can put these two listview in scroll view, and disable the scrolling of listviews, Now you will have single scrollview for two listviews. 

    <ScrollView 
     android:id="@+id/bottomformline" 
     android:layout_width="fill_parent" > 


      <your.package.name.NestedListView 
       android:id="@+id/list_view" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       android:background="#FFFFFF" /> 

      <your.package.name.NestedListView 
       android:id="@+id/follow_list_view" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       android:background="#FFFFFF" /> 
</ScrollView> 

    public class NestedListView extends ListView implements OnTouchListener, OnScrollListener { 

     private int listViewTouchAction; 
     private static final int MAXIMUM_LIST_ITEMS_VIEWABLE = 99; 

     public NestedListView(Context context, AttributeSet attrs) { 
      super(context, attrs); 
      listViewTouchAction = -1; 
      setOnScrollListener(this); 
      setOnTouchListener(this); 
     } 

     @Override 
     public void onScroll(AbsListView view, int firstVisibleItem, 
       int visibleItemCount, int totalItemCount) { 
      if (getAdapter() != null && getAdapter().getCount() > MAXIMUM_LIST_ITEMS_VIEWABLE) { 
       if (listViewTouchAction == MotionEvent.ACTION_MOVE) { 
        scrollBy(0, -1); 
       } 
      } 
     } 

     @Override 
     public void onScrollStateChanged(AbsListView view, int scrollState) { 
     } 

     @Override 
     protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
      super.onMeasure(widthMeasureSpec, heightMeasureSpec); 

      int newHeight = 0; 
      final int heightMode = MeasureSpec.getMode(heightMeasureSpec); 
      int heightSize = MeasureSpec.getSize(heightMeasureSpec); 
      if (heightMode != MeasureSpec.EXACTLY) { 
       ListAdapter listAdapter = getAdapter(); 
       if (listAdapter != null && !listAdapter.isEmpty()) { 
        int listPosition = 0; 
        for (listPosition = 0; listPosition < listAdapter.getCount() 
          && listPosition < MAXIMUM_LIST_ITEMS_VIEWABLE; listPosition++) { 
         View listItem = listAdapter.getView(listPosition, null, this); 
         //now it will not throw a NPE if listItem is a ViewGroup instance 
         if (listItem instanceof ViewGroup){ 
          listItem.setLayoutParams(new LayoutParams(
            LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); 
         } 
         listItem.measure(widthMeasureSpec, heightMeasureSpec); 
         newHeight += listItem.getMeasuredHeight(); 
        } 
        newHeight += getDividerHeight() * listPosition; 
       } 
       if ((heightMode == MeasureSpec.AT_MOST) && (newHeight > heightSize)) { 
        if (newHeight > heightSize) { 
         newHeight = heightSize; 
        } 
       } 
      } else { 
       newHeight = getMeasuredHeight(); 
      } 
      setMeasuredDimension(getMeasuredWidth(), newHeight); 
     } 

     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      if (getAdapter() != null && getAdapter().getCount() > MAXIMUM_LIST_ITEMS_VIEWABLE) { 
       if (listViewTouchAction == MotionEvent.ACTION_MOVE) { 
        scrollBy(0, 1); 
       } 
      } 
      return false; 
     } 
    }
