TabLayout中的ListView不起作用

Question

嗨我似乎无法得到在我的标签布局中工作的列表视图。它在list.setAdapter（mSchedule）处保持失败; 这是我的代码和XML。感谢您的任何输入

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ListView的标签。仅仅因为它是FrameLayout的孩子，不会自动为它设置一个标签。 Here is a sample project演示如何带着FrameLayout的孩子，并将它们作为标签添加到TabHost。
