我在我的应用程序两个标签，我想在菜单根据标签更改。

下面我做什么

  TabHost tabHost = tabHost = getTabHost（）;

    则tabspec photospec = tabHost.newTabSpec（照片）;
    photospec.setIndicator（照片，getResources（）getDrawable（R.drawable.photo）。）;
    意图photosIntent =新的意图（这一点，Photos.class）;
    photospec.setContent（photosIntent）;



    则tabspec songspec = tabHost.newTabSpec（诗经）;
    songspec.setIndicator（诗经，getResources（）getDrawable（R.drawable.songs））;
    意图songsIntent =新的意图（这一点，Songs.class）;
    songspec.setContent（songsIntent）;

    tabHost.addTab（photospec）; //将照片添加标签
    tabHost.addTab（songspec）; //将歌曲添加标签
 

现在当用户点击照片选项卡上，我想显示一个菜单，编辑图片，当用户点击歌曲标签我想显示控制歌曲的顺序的菜单。我想这每当用户点击任何标签做。

  @覆盖
 公共布尔onOptionsItemSelected（菜单项项）{
    INT currentTab = tabHost.getCurrentTab（）;
    如果（currentTab == 0）
        startActivity（新意图（这一点，Photosoptions.class））;
    如果（currentTab == 1）
        {
           startActivity（新意图（这一点，Songsoptions.class））;
                      }
            返回true;
        }



      @覆盖
    公共布尔prepareOptionsMenu（功能菜单）在{

        MenuInflater充气= getMenuInflater（）;
        INT currentTab = tabHost.getCurrentTab（）;

        如果（currentTab == 0）{
            menu.clear（）;
            inflater.inflate（R.menu.first，菜单）;
           closeOptionsMenu（）;

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

       }
        返回super.on prepareOptionsMenu（菜单）;
    }
 

解决方案

您可以使用下面的code：

  @覆盖
 公共布尔prepareOptionsMenu（功能菜单）在{
        // TODO自动生成方法存根
        MenuInflater充气= getMenuInflater（）;
        INT currentTab = tabHost.getCurrentTab（）;
        Toast.makeText（getApplicationContext（），currentTab +，Toast.LENGTH_SHORT）;
        menu.clear（）;
        如果（currentTab == 0）{
            inflater.inflate（R.menu.first，菜单）; //菜单photospec。
        } 其他 {
            inflater.inflate（R.menu.second，菜单）; //菜单songspec
        }
        返回super.on prepareOptionsMenu（菜单）;
    }
 

不需要你的 onCreateOptionsMenu ，然后你必须处理项目点击与 onOptionsItemSelected

I have two tabs in my application and I want the menu to change depending on the Tab.

Here what I did

  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

Now When the user clicks on the photos tab, I would like to display a menu for editing pictures and when the user clicks on songs tab I want to display a menu of controlling the order of the songs. I want to do this each time the user click on any of the tabs.

 @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);
           closeOptionsMenu();

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

       }
        return super.onPrepareOptionsMenu(menu);
    }

you can use following code:

@Override
 public boolean onPrepareOptionsMenu(Menu menu) {
        // TODO Auto-generated method stub
        MenuInflater inflater = getMenuInflater();
        int currentTab = tabHost.getCurrentTab();
        Toast.makeText(getApplicationContext(), currentTab+"", Toast.LENGTH_SHORT);
        menu.clear();
        if (currentTab == 0) {
            inflater.inflate(R.menu.first, menu);  //  menu for photospec.
        } else {
            inflater.inflate(R.menu.second, menu);  // menu for songspec
        }
        return super.onPrepareOptionsMenu(menu);
    }

you don't needed onCreateOptionsMenu and you must handle item click with onOptionsItemSelected
