在對話框中獲取操作欄/導航欄

Question

我試圖使用標籤欄/操作欄彈出對話框，但我在對話框後面顯示對話框和標籤欄。如何獲得對話框中的標籤欄？我非常感謝任何幫助。感謝提前。

public class MainActivity extends Activity implements TabListener { 

     final String[] page_titles = new String[]{"Home", "contact", "Apps"}; 
     //this will go the description TextView 
      final String[] desc = new String[]{ 
       "This is the homepage ", 
       "contact", 
       "apps" 
     }; 
    ViewPager pager; 

    ActionBar bar; 

    Dialog dialog; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 


     dialog = new Dialog(MainActivity.this); 

     dialog.setContentView(R.layout.activity_main); 



      pager = (ViewPager)dialog. findViewById(R.id.pager); 

      bar = getActionBar(); 

      myAdaptertest1 mAdapter = new myAdaptertest1(this); 

      bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 

      bar.setHomeButtonEnabled(false); 

      pager.setAdapter(mAdapter); 
      pager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() { 

       @Override 
       public void onPageSelected(int position) { 

        bar.setSelectedNavigationItem(position); 
       } 
      }); 



      Tab hometab = bar.newTab(); 
      hometab.setText("Home"); 
      hometab.setTabListener(this); 
      bar.addTab(hometab); 

      Tab cameratab = bar.newTab(); 
      cameratab.setText("contact"); 
      cameratab.setTabListener(this); 
      bar.addTab(cameratab); 

      Tab exploretab = bar.newTab(); 
      exploretab.setText("apps"); 
      exploretab.setTabListener(this); 
      bar.addTab(exploretab); 


      bar.show(); 
      bar.setDisplayShowTitleEnabled(false); 
      bar.setDisplayShowHomeEnabled(false); 


      dialog.show(); 
    } 


    private class myAdaptertest1 extends PagerAdapter{ 

     Context context; 

     public myAdaptertest1(Context c){ 
      this.context = c; 
     } 

     @Override 
     public int getCount() { 
      // TODO Auto-generated method stub 
       return page_titles.length; 
     } 

     @Override 
     public boolean isViewFromObject(View v, Object o) { 
      // TODO Auto-generated method stub 
       return v.equals(o); 
     } 





     public Object instantiateItem(View pager, int position) { 
      final LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      View vi = inflater.inflate(R.layout.page, null, false); 

      TextView title = (TextView)vi.findViewById(R.id.tvTitle); 
      TextView description = (TextView) vi.findViewById(R.id.tvdesc); 

      title.setText(page_titles[position]); 
      description.setText(desc[position]); 

      //This is very important 
      ((ViewPager) pager).addView(vi, 0); 

      return vi; 
     } 

     @Override 
     public void destroyItem(View pager, int position, Object view) { 
      ((ViewPager) pager).removeView((View) view); 
     } 


    } 


    @Override 
    public void onTabReselected(Tab tab, FragmentTransaction ft) { 
     // TODO Auto-generated method stub 

    } 


    @Override 
    public void onTabSelected(Tab tab, FragmentTransaction ft) { 
     // TODO Auto-generated method stub 
     pager.setCurrentItem(tab.getPosition()); 
    } 


    @Override 
    public void onTabUnselected(Tab tab, FragmentTransaction ft) { 
     // TODO Auto-generated method stub 

    } 


    public static void showAsPopup(Activity activity) { 
     //To show activity as dialog and dim the background, you need to declare android:theme="@style/PopupTheme" on for the chosen activity on the manifest 
     activity.requestWindowFeature(Window.FEATURE_ACTION_BAR); 
     activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND, 
       WindowManager.LayoutParams.FLAG_DIM_BEHIND); 
     LayoutParams params = activity.getWindow().getAttributes(); 
     params.height = LayoutParams.FILL_PARENT; 
     params.width = 850; //fixed width 
     params.alpha = 1.0f; 
     params.dimAmount = 0.5f; 
     activity.getWindow().setAttributes((android.view.WindowManager.LayoutParams) params); 
    } 

}

如果你想要的是標籤（這意味着你不需要你的對話框中的操作欄），試圖在定製對話框佈局添加TabHost和TabWidget秒。你應該不要把一個操作欄放在對話框中。
