Question

我需要在片段布局中显示所有呼叫记录，对于样本我只是试图显示该电话号码和值。这里是字符串phNum。当我尝试显示所有通话记录时，由于Static中的List<model>字符串，它仅显示最后通话记录。我知道，我使用StringBuffer来收集。所以对于Here List<Model>我需要传递字符串缓冲区我不能这样做。如果可能的话，请提出解决这个问题的想法。

Solution here

    public class CallLogFragment extends Fragment
{
    private View view;
    private ListView list_calllog;
    private ArrayList<HashMap<String,String>> callLog;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) 
    {
        if(view==null)
        {
            view=inflater.inflate(R.layout.fragment_call_log_layout, container,false);
        }   
        else
        {
            ViewGroup parent = (ViewGroup) view.getParent();
            parent.removeView(view);
        }   

        callLog=getCallLog();
        CustomCallLogListAdapter adapter=new CustomCallLogListAdapter(getActivity(),R.layout.row_call_log_layout,callLog);
        list_calllog=(ListView)view.findViewById(R.id.list_calllog);
        list_calllog.setAdapter(adapter);
        return view;
    }

    @SuppressLint("NewApi")
    public ArrayList<HashMap<String,String>> getCallLog()
    {
        ArrayList<HashMap<String,String>> callLog=new ArrayList<HashMap<String,String>>();
        CursorLoader cursorLoader=new CursorLoader(getActivity(),CallLog.Calls.CONTENT_URI, null, null, null, null);
        Cursor cursor=cursorLoader.loadInBackground();
        if(cursor.moveToFirst())
        {
            while (cursor.moveToNext())
            {
                HashMap<String,String> hashMap=new HashMap<String, String>();
                hashMap.put(CallLog.Calls.NUMBER, cursor.getString(cursor.getColumnIndex(CallLog.Calls.NUMBER)));
                hashMap.put(CallLog.Calls.DATE, cursor.getString(cursor.getColumnIndex(CallLog.Calls.DATE)));
                hashMap.put(CallLog.Calls.DURATION, cursor.getString(cursor.getColumnIndex(CallLog.Calls.DURATION)));   
                callLog.add(hashMap);
            }
        }
        return callLog;
    }
}
