在Android中的標籤之間切換時的更新菜單

Question

我的應用程序中有兩個標籤，我希望菜單根據標籤進行更改。

TabHost tabHost = tabHost = getTabHost(); 

TabSpec photospec = tabHost.newTabSpec("Photos"); 
photospec.setIndicator("Photos", getResources().getDrawable(R.drawable.photo)); 
Intent photosIntent = new Intent(this, Photos.class); 
photospec.setContent(photosIntent); 



TabSpec songspec = tabHost.newTabSpec("Songs");  
songspec.setIndicator("Songs", getResources().getDrawable(R.drawable.songs)); 
Intent songsIntent = new Intent(this, Songs.class); 
songspec.setContent(songsIntent); 

tabHost.addTab(photospec); // Adding photos tab 
tabHost.addTab(songspec); // Adding songs tab 



@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
int currentTab = tabHost.getCurrentTab(); 
if (currentTab == 0) 
    startActivity(new Intent(this, Photosoptions.class)); 
if (currentTab == 1) 
    { 
     startActivity(new Intent(this, Songsoptions.class)); 
        } 
     return true; 
    } 



    @Override 
public boolean onPrepareOptionsMenu(Menu menu) { 

    MenuInflater inflater = getMenuInflater(); 
    int currentTab = tabHost.getCurrentTab(); 

    if (currentTab == 0){ 
     menu.clear(); 
     inflater.inflate(R.menu.first, menu); 

     } 
    if (currentTab ==1){ 
     menu.clear(); 
     inflater.inflate(R.menu.second, menu); 

    } 
    return super.onPrepareOptionsMenu(menu); 
} 



    tabHost.setOnTabChangedListener(new OnTabChangeListener(){ 
     @Override 
     public void onTabChanged(String tabId) { 
      closeOptionsMenu(); 

     }}); 

現在，當我切換到歌曲標籤時，照片菜單仍然存在，直到我點擊它然後出現歌曲菜單。我想要菜單得到更新，一旦我點擊標籤

您正在準備TabActivity中的選項菜單。請在個人活動中準備選項菜單。所以當你在那個活動中時，只會顯示選項菜單。
