嗨，我似乎无法在我的选项卡布局中使用列表视图。它在 list.setAdapter(mSchedule); 处一直失败；这是我的代码和 XML。感谢您的任何意见

   public class ttTuesday extends Activity {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        ListView list = (ListView) findViewById(R.id.LISTVIEW);
    ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();
    HashMap<String, String> map = new HashMap<String, String>();

    for(int i=0; i<About.timetable.length; i++){

        //check if sorting by category and make sure at least one category is TRUE
        if(About.timetable[i][0].contains("Tuesday")){

                map = new HashMap<String, String>();
                map.put("time", About.timetable[i][1] + "-" + About.timetable[i][2]);
                map.put("location", "\tLocation: " + About.timetable[i][4]);
                map.put("subject","\tSubject: " +  About.timetable[i][3]);
                mylist.add(map);


        }
}
    final SimpleAdapter mSchedule = new SimpleAdapter(this, mylist, R.layout.timetableday,
            new String[] {"time", "location", "subject"}, new int[] {R.id.TIME, R.id.LOCATION, R.id.SUBJECT});
    list.setAdapter(mSchedule);
    list.setTextFilterEnabled(true);

}

}

你没有把它ListView放在一个标签里。仅仅因为它是的子级FrameLayout不会自动为其设置选项卡。这是一个示例项目，演示如何获取 a 的子级FrameLayout并将它们作为选项卡添加到TabHost.
