작업 표시 줄 동작보기가 작동하지 않습니다.

Question

작업 모음에서 축소 가능한 EditText를 만들려고합니다. 나는 Android Developers guide을 따라 갔다. 그러나 검색 아이콘을 클릭해도 아무런 변화가 없습니다.

어떻게해야합니까?

여기 내 코드입니다.

활동 :

public class ElementPagerActivity extends ActionBarActivity 
       implements ElementListFragment.onElementClickListener, 
          CalculateFragment.OnCalculateClickListener{ 

ViewPager theViewPager; 
private ActionBar actionBar; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    actionBar = getSupportActionBar(); 

    theViewPager = new ViewPager(this); 
    theViewPager.setId(0x1); 

    theViewPager.setAdapter(new FragmentStatePagerAdapter(getSupportFragmentManager()) { 
     @Override 
     public Fragment getItem(int position) { 
      if(position == 0){ 
       return new ElementListFragment(); 
      } return Element.values()[position - 1].toFragment(); 
     } 

     @Override 
     public int getCount() { 
      return Element.values().length + 1; 
     } 
    }); 

    theViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { 
     @Override 
     public void onPageScrolled(int i, float v, int i2) { 

     } 

     @Override 
     public void onPageSelected(int position) { 
      invalidateOptionsMenu(); 
      if(position == 0){ 
       actionBar.setTitle(R.string.Element_info_activity_label); 
       actionBar.selectTab(null); 
      } else { 
       actionBar.setTitle(Element.values()[position - 1].getName()); 
       actionBar.selectTab(actionBar.getTabAt(position - 1)); 
      } 
     } 

     @Override 
     public void onPageScrollStateChanged(int i) { 

     } 
    }); 


    actionBar = actionBar; 
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 

    ActionBar.TabListener tabListener = new ActionBar.TabListener(){ 

     @Override 
     public void onTabSelected(ActionBar.Tab tab, android.support.v4.app.FragmentTransaction fragmentTransaction) { 
      int position = tab.getPosition(); 
      theViewPager.setCurrentItem(position + 1, true); 
     } 

     @Override 
     public void onTabUnselected(ActionBar.Tab tab, android.support.v4.app.FragmentTransaction fragmentTransaction) { 

     } 

     @Override 
     public void onTabReselected(ActionBar.Tab tab, android.support.v4.app.FragmentTransaction fragmentTransaction) { 
      int position = tab.getPosition(); 
      theViewPager.setCurrentItem(position + 1, true); 
     } 
    }; 

    for (int i = 0; i < Element.values().length; i++){ 
    actionBar.addTab(
      actionBar.newTab() 
      .setText(Element.values()[i].getName()) 
      .setTabListener(tabListener)); 
    } 

    theViewPager.setCurrentItem(0); 
    actionBar.selectTab(null); 

    setContentView(theViewPager); 

} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.element_pager, menu); 
    menu.findItem(R.id.pager_activity_show_list_action).setVisible(!(theViewPager.getCurrentItem() == 0)); 
    menu.findItem(R.id.pager_activity_edit_text_action).expandActionView(); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long 
    // as you specify a parent activity in AndroidManifest.xml. 
    int id = item.getItemId(); 
    if (id == R.id.pager_activity_show_list_action){ 
     theViewPager.setCurrentItem(0, true); 
     return true; 
    } else if (id == R.id.pager_activity_edit_text_action){ 
     return false; 
    } 
    return super.onOptionsItemSelected(item); 
} 

@Override 
public void onBackPressed() { 
    if (theViewPager.getCurrentItem() == 0){ 
     super.onBackPressed(); 
    } else { 
     theViewPager.setCurrentItem(0); 
    } 
} 

@Override 
public void onElementClick(int position) { 
    theViewPager.setCurrentItem(position + 1, true); 
} 

@Override 
public Element onRequestElement() { 
    return Element.values()[theViewPager.getCurrentItem() - 1]; 
} 
} 

메뉴 자원 :

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
xmlns:tools="http://schemas.android.com/tools" 
tools:context=".MainActivity" > 

<item android:id="@+id/pager_activity_edit_text_action" 
    app:showAsAction="always|collapseActionView" 
    android:title="text here" 
    android:icon="@android:drawable/ic_menu_search" 
    android:actionLayout="@layout/test"/> 

<item android:id="@+id/pager_activity_show_list_action" 
    android:title="@string/action_bar_pager_show_list" 
    android:orderInCategory="100" 
    app:showAsAction="ifRoom|withText" /> 

</menu> 

액션 레이아웃 (test.xml) :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 

<EditText 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:hint="element" 
    android:inputType="textCapWords"/> 

</LinearLayout>

당신은 당신을 위해 쉽게 일을 조금 만들 것입니다 SearchView를 사용할 수 있습니다. 여기

<menu xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:id="@+id/search" 
      android:title="@string/search_title" 
      android:icon="@drawable/ic_search" 
      android:showAsAction="collapseActionView|ifRoom" 
      android:actionViewClass="android.widget.SearchView" /> 
</menu>
