我在我的项目中使用 actionbarsherlock，我正在尝试从片段中操作操作栏......

所以在我显示的第一个片段中，我重写了 onPrepareOptionsMenu 以使操作栏无效并更改标题......但是当我尝试调用 supportInvalidateOptionsMenu() 时，我得到一个 java.lang.StackOverflowError（虽然它不会在 android 4.3 上发生）.. .

我已经尝试过Delyan 的解决方案但没有成功......我的代码和日志如下，有什么建议吗？提前致谢

@Override
public void onPrepareOptionsMenu(Menu menu){
    super.onPrepareOptionsMenu(menu);
    Log.e("CategoriasLista", "Executou onPrepareOptionsMenu");
    int currentTab = ((MainActivity)getSherlockActivity()).getTabHost().getCurrentTab();
    if(currentTab==0){
        ActionBar bar = getSherlockActivity().getSupportActionBar();
        //getSherlockActivity().supportInvalidateOptionsMenu();
        ((MainActivity)getSherlockActivity()).runOnUiThread(new Runnable(){
            @Override
            public void run(){
                ((MainActivity)getSherlockActivity()).supportInvalidateOptionsMenu();
            }
        });
        bar.setNavigationMode(com.actionbarsherlock.app.ActionBar.NAVIGATION_MODE_STANDARD);
        bar.setTitle("Categorias");

    }
}

它很可能会抛出异常，因为您试图在错误的地方使其无效。

如果您只是想更改标题，请将逻辑移至 onActivityCreated 方法。

@Override
protected void onActivityCreated(Bundle savedInstanceState) {
  super.onActivityCreated(savedInstanceState);
  getSherlockActivity.setTitle("Categorias");
}
