Question

我在我的项目中使用了actionbarsherlock，我正试图从片段中操纵动作栏......

所以在我显示的第一个片段中，我重写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（它在android 4.3上不会发生）...

我已经尝试Delyan's solution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");

    }
}

Answer 1

最有可能抛出异常，因为你试图在错误的地方使它失效。

如果您只想更改标题，请将逻辑移至onActivityCreated方法。

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

方法supportInvalidateOptionsMenu在android 2.3上抛出stackoverflower
