推荐答案

将您的项目设置为 appcompat v7 库以供参考，请参见

setup your project to appcompat v7 library for reference see http://developer.android.com/guide/topics/ui/actionbar.html#Adding
and

@Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ActionBar actionBar = getActionBar();
    actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_HOME
        | ActionBar.DISPLAY_SHOW_TITLE | ActionBar.DISPLAY_SHOW_CUSTOM);
  }
