android – 构造函数ArrayAdapter未定义

我有一个方法,initializeViews,它在最后一行遇到ArrayAdapter构造函数未定义错误.

该方法位于F1Fragment中,它扩展了MainFragment.然后将MainFragment附加到Activity.

我们不能在ArrayAdapter< string>中给出片段的上下文吗?构造函数?我是Android新手.请指正.提前致谢.

private void initializeViews(RelativeLayout contentLayout) {
    leaguesListView = ( ListView ) contentLayout.findViewById ( R.id.leaguesListView );
    progressLinear  =   (LinearLayout) contentLayout.findViewById ( R.id.progressLeagues );
    values= new String[] { "RedBullRacing", "McLaren", "Lotus",
      "ForceIndia", "HRT", "Ferrari" };
    adapter= new ArrayAdapter<String>(F1Fragment.this, android.R.layout.simple_list_item_1, android.R.id.text1, values);
}
最佳答案
将F1Fragment.this更改为getActivity().片段不是上下文.
