getMenuInflater出错

Question

MainActivity

public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.

    getMenuInflater().inflate(R.menu.main, menu);
    MenuItem item = menu.findItem(R.id.menu_item_share);

    // Fetch and store ShareActionProvider
    ShareActionProvider mShare = (ShareActionProvider) item.getActionProvider();

    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    shareIntent.setAction(Intent.ACTION_SEND);
    shareIntent.setType("text.plain");
    shareIntent.putExtra(Intent.EXTRA_TEXT,"Try this e-Learning app!");

    mShare.setShareIntent(shareIntent);

    menu.add(0, 1, 1, "Home");
    menu.add(0, 2, 2, "About");
    menu.add(0, 3, 3, "Help");
    menu.add(0, 4, 4, "Settings");
    menu.add(0, 5, 5, "Exit");

    return true;
}

添加getMenuInflater（）。inflate（R.menu.main，menu）后，

我的应用程序的选项菜单突然出现一个额外的＆＃34;设置＆＃34;哪个不起作用。我尝试删除getMenuInflater（）和这些相关的代码，然后是＆＃34;设置＆＃34; disappered。有什么解决方案吗？请帮忙！
