在选项卡ViewPager中使用SearchView

Question

我正在参考这个教程。

我想在TabsViewpager中添加一个SearchView，如链接：图片1 http://www.uphinh.vn/image/stream/1386201.png 但是我的应用程序中，搜索视图没有出现在TabsViewpager中，如链接：图片2 http://www.uphinh.vn/image/stream/1386202.png 我无法修复它。

这是我的代码：

• This is FragmentTab3.java:

  public class FragmentTab3  extends SherlockFragment  implements OnQueryTextListener {
  
      TextView mSearchText;
      @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container,
              Bundle savedInstanceState) {
          setHasOptionsMenu(true);
  
          // Get the view from fragmenttab1.xml
          View view = inflater.inflate(R.layout.fragmenttab3, container, false);
          mSearchText =(TextView)view.findViewById(R.id.test);
  
          return view;
      }
  
      @Override
      public void onSaveInstanceState(Bundle outState) {
          super.onSaveInstanceState(outState);
          setUserVisibleHint(true);
      }
  
  
  
  @Override
  public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
      // TODO Auto-generated method stub
      super.onCreateOptionsMenu(menu, inflater);
  
      inflater.inflate(R.menu.menutab3, menu);
  
        SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
          searchView.setQueryHint("Search");
  
          //searchView.setBackgroundColor(Color.WHITE);
          searchView.setOnQueryTextListener(this);
  }
  
      @Override
      public boolean onQueryTextChange(String newText) {
          // TODO Auto-generated method stub
          mSearchText.setText("Query so far:"+newText);
             mSearchText.setTextColor(Color.GREEN);
          return false;
      }
  
      @Override
      public boolean onQueryTextSubmit(String query) {
          // TODO Auto-generated method stub
          mSearchText.setText("Searching for: " + query + "...");
             mSearchText.setTextColor(Color.RED);
          return false;
      }
  
  }
  

• This is fragmenttab3.xml

 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    <TextView
        android:id="@+id/test"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="@string/Fragment3" />

</RelativeLayout>

• 这是menutab3.xml文件

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
   <item android:id="@+id/action_search"
          android:icon="@android:drawable/ic_menu_search"
          android:title="Action Bar Search"
          android:showAsAction="ifRoom|withText|collapseActionView"
          android:actionViewClass="android.widget.SearchView" /> 
  <item
        android:id="@+id/gamepad"
        android:title="@string/gamepad"
        android:icon="@drawable/gamepad"
        android:showAsAction="ifRoom|withText"
    />
   <item
        android:id="@+id/camera"
        android:title="@string/camera"
        android:icon="@drawable/camera"
        android:showAsAction="ifRoom|withText"
    />

</menu>

我使用了ActionBarSherlock库。

我无法解决这个问题。

这是一个简单的带有ViewPager的SearchView示例。

接口IDataCallback。

import java.util.ArrayList;

public interface IDataCallback {

    void onFragmentCreated( ArrayList<String> listData);
}

Interface IFragmentListener

public interface IFragmentListener {

    void addiSearch(ISearch iSearch);

    void removeISearch(ISearch iSearch);
}

Interface ISearch

public interface ISearch {

    void onTextQuery(String text);
}
