我的代码有问题:

我想用 Google AppEngine 制作一个高分列表,它可以工作。Google AppEngine 返回一个经过解析并填充到布局中的字符串。活动 HighscoreListe 连接到 AppEngine 并将获取此字符串。

我在下面写的 Highscore 布局的问题是,这个活动(HighscoreListe)在我启动 TabLayout 时启动了多次。所以我得到了一个 StringIndexOutOfBoundsException。

当我更改为 Tab 2 时,我想启动 Intent2,当我更改为 Tab3 时,我想启动 Intent3。这样当我点击这个难度时,只会在第 2 或第 3 难度中加载高分。

public class HighscoreTabLayout extends TabActivity{

@Override
   public void onCreate(Bundle savedInstanceState) {

       super.onCreate(savedInstanceState);

       TabHost tabHost = getTabHost();

       System.out.println(MenuMainActivity.getDifficulties());
       int diffCount = -1;
       System.out.println(diffCount);

       TabSpec tabSpec1 = tabHost.newTabSpec(MenuMainActivity.getDifficulties()[++diffCount].getName());
       // setting Title and Icon for the Tab
       tabSpec1.setIndicator(MenuMainActivity.getDifficulties()[diffCount].getName());//, getResources().getDrawable(R.drawable.icon_photos_tab));
       Intent intent1 = new Intent(this, HighscoreListe.class);
       intent1.putExtra("name", MenuMainActivity.getDifficulties()[diffCount].getName());
       tabSpec1.setContent(intent1);
       System.out.println(diffCount);

       TabSpec tabSpec2 = tabHost.newTabSpec(MenuMainActivity.getDifficulties()[++diffCount].getName());
       tabSpec2.setIndicator(MenuMainActivity.getDifficulties()[diffCount].getName());//, getResources().getDrawable(R.drawable.icon_songs_tab));
       Intent intent2 = new Intent(this, HighscoreListe.class);
       intent2.putExtra("name", MenuMainActivity.getDifficulties()[diffCount].getName());
       tabSpec2.setContent(intent2);
       System.out.println(diffCount);

       TabSpec tabSpec3 = tabHost.newTabSpec(MenuMainActivity.getDifficulties()[++diffCount].getName());
       tabSpec3.setIndicator(MenuMainActivity.getDifficulties()[diffCount].getName());//, getResources().getDrawable(R.drawable.icon_videos_tab));
       Intent intent3 = new Intent(this, HighscoreListe.class);
       intent3.putExtra("name", MenuMainActivity.getDifficulties()[diffCount].getName());
       tabSpec3.setContent(intent3);
       System.out.println(diffCount);

       TabSpec tabSpec4 = tabHost.newTabSpec(MenuMainActivity.getDifficulties()[++diffCount].getName());
       tabSpec4.setIndicator(MenuMainActivity.getDifficulties()[diffCount].getName());//, getResources().getDrawable(R.drawable.icon_videos_tab));
       Intent intent4 = new Intent(this, HighscoreListe.class);
       intent4.putExtra("name", MenuMainActivity.getDifficulties()[diffCount].getName());
       tabSpec4.setContent(intent4);
       System.out.println(diffCount);

       // Adding all TabSpec to TabHost
       tabHost.addTab(tabSpec1);
       tabHost.addTab(tabSpec2);
       tabHost.addTab(tabSpec3);
       tabHost.addTab(tabSpec4);

       tabHost.setCurrentTab(1);


}

}

如果我明白你的意思,你应该在 tabhost 上设置 tab chage listner:

` mTab​​Host.setOnTabChangedListener(new OnTabChangeListener() {

        @Override
        public void onTabChanged(String tabId) {
            // TODO Auto-generated method stub

        }
    })`
