标签主机片段保存实例

Question

我有一个带有5个标签的Tabhost：tab1，tab2，tab3，tab4，tab5
并且它们都具有相同的片段，内容不同 我的片段onCreateView方法有以下代码：

switch(tabtag){
   case 1:
       loaddata1();
       break;
   case 2:
       loaddata2();
       break;
   case 3:
       loaddata3();
       break;
   case 4:
       loaddata4();
       break;
   case 5:
       loaddata5();
       break;
}

我正确加载了相关数据，但我希望每次只为每个标签加载一次数据 我使用onSaveInstanceState和onActivityCreated方法：

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putBoolean("1", isFirsttime1);
    outState.putBoolean("2", isFirsttime2);
    outState.putBoolean("3", isFirsttime3);
    outState.putBoolean("4", isFirsttime4);
    outState.putBoolean("5", isFirsttime5);
    outState.putBoolean("6", isFirsttime6);
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    if (savedInstanceState != null) {
        // Restore last state for checked position.
        isFirsttime1 = savedInstanceState.getBoolean("1");
        isFirsttime2 = savedInstanceState.getBoolean("2");
        isFirsttime3 = savedInstanceState.getBoolean("3");
        isFirsttime4 = savedInstanceState.getBoolean("4");
        isFirsttime5 = savedInstanceState.getBoolean("5");
        isFirsttime6 = savedInstanceState.getBoolean("6");

    }
}

所以在onCreateView我在每个开关案例中添加了这段代码：

if (isFirsttime){
   loaddata();
}
else{
   //use from my view state
}

但它不能像那样工作，我认为因为我再次使用相同的片段，onSaveInstanceState方法没有被调用。

我该怎么解决呢？ 提前谢谢。
