【问题描述】：

我想像这样在Listview 的第一行设置一个ViewFlipper

我可以像这样在列表视图顶部设置视图翻转器：

mListView = (ListView) findViewById( R.id.mainListView );
viewFlipper =(ViewFlipper)findViewById(R.id.viewFlipper1);
setViewFlipperView();
CustomGestureDetector customGestureDetector = new CustomGestureDetector();
mGestureDetector = new GestureDetector(this, customGestureDetector);

String[] abc = new String[]  "A", "B", "C", "D",
                                  "E", "F", "G", "H","I","J","K","L","M","N","O","P","Q","R","S"
                                  ,"T","U","V","W","X","Y","Z";  
ArrayList<String> abcList = new ArrayList<String>();
abcList.addAll( Arrays.asList(abc) );

listAdapter = new ArrayAdapter<String>(this, R.layout.simplerow, abcList);
mListView.setAdapter( listAdapter );

private View setViewFlipperView()
  int[] resources = 
            R.drawable.ic_launcher,
            R.drawable.ic_launcher,
            R.drawable.ic_launcher,
            R.drawable.ic_launcher,
            R.drawable.ic_launcher,
            R.drawable.ic_launcher
    ;

    for (int i = 0; i < resources.length; i++) 
        ImageView imageView = new ImageView(this);
        imageView.setImageResource(resources[i]);
        viewFlipper.addView(imageView,i);
    
  return viewFlipper;

 
@Override
public boolean dispatchTouchEvent(MotionEvent ev) 
     mGestureDetector.onTouchEvent(ev);
    return super.dispatchTouchEvent(ev);

 @Override
public boolean onTouchEvent(MotionEvent event) 
    mGestureDetector.onTouchEvent(event);
    return super.onTouchEvent(event);

 class CustomGestureDetector extends GestureDetector.SimpleOnGestureListener    
        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float   velocityX, float velocityY) 
             // Swipe left (next)
            if (e1.getX() > e2.getX()) 
                viewFlipper.setInAnimation(context, R.anim.left_in);
                viewFlipper.setOutAnimation(context, R.anim.left_out);

                viewFlipper.showNext();
            

            // Swipe right (previous)
            if (e1.getX() < e2.getX()) 
                viewFlipper.setInAnimation(context, R.anim.right_in);
                viewFlipper.setOutAnimation(context, R.anim.right_out);

                viewFlipper.showPrevious();
            

            return super.onFling(e1, e2, velocityX, velocityY);
        
    

xml 看起来像：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_
android:layout_>

<ViewFlipper
    android:id="@+id/viewFlipper1"
    android:layout_
    android:layout_ >
</ViewFlipper>

<ListView android:layout_ 
  android:layout_ 
  android:id="@+id/mainListView">
</ListView>

但是，当滚动 listview 视图翻转器保持在顶部时，现在我的问题是，是否可以在 listview 的顶行设置 ViewFlipper 以便它在 listview 滚动时也滚动。我想我的问题很清楚。请帮忙。

您可以在 listview 上添加虚拟视图。

只需添加 viewflipper 布局作为列表视图的标题 :)

【参考方案1】：

只需这样做 .. 添加视图翻转器作为列表视图的标题，如果您在列表视图中只需要一个视图翻转器，它将正常工作。如果您需要更多，那么您应该在适配器 getView() 中执行此操作。

LayoutInflater  inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
convertViewHeader = inflater.inflate(R.layout.YourFlipperview , null);
ViewFlipper flipper=(ViewFlipper)convertViewHeader.findViewById(R.id.flipperId); 

listView.addHeaderView(convertViewHeader, null, false);

随心所欲地使用脚蹼。如果有任何困惑，请告诉我

【参考方案2】：

问题已解决我已经得到了我的问题的解决方案，通过将 viewflipper 视图添加为 Listview mListView.addHeaderView(flipperView); 的 HeaderView，现在 viewFlipper 视图也在滚动列表视图项目，我在代码中做了一些更改：

 LayoutInflater  inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
convertViewHeader = inflater.inflate(R.layout.myflipperiew , null);
ViewFlipper flipper=(ViewFlipper)convertViewHeader.findViewById(R.id.myflipper);
mListView = (ListView) findViewById( R.id.mainListView );
mListView.addHeaderView(flipper);
