Question

我正在尝试显示来自我的手机的已拨电话记录，并且我获得了成功。但现在的问题是，当我将数据发送到我的getter setter类时，它会显示一些错误，我不知道如何摆脱它。

public class OneFragment extends Fragment {

RecyclerView recyclerView;

public OneFragment() {

}

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    return inflater.inflate(R.layout.fragment_one, container, false);
}

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    recyclerView = (RecyclerView) getView().findViewById(R.id.fragRecycler1);
    LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
    recyclerView.setLayoutManager(linearLayoutManager);
    getDialledList();
}

private void getDialledList() {
    List<CallList> callList = new ArrayList();
    CallList logList;
    String strOrder = android.provider.CallLog.Calls.DATE + " DESC";
    ContentResolver cR = getActivity().getContentResolver();

    if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.READ_CALL_LOG) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling
        //    ActivityCompat#requestPermissions
        // here to request the missing permissions, and then overriding
        //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
        //                                          int[] grantResults)
        // to handle the case where the user grants the permission. See the documentation
        // for ActivityCompat#requestPermissions for more details.
        return;
    }
    Cursor cursor = cR.query(CallLog.Calls.CONTENT_URI, null, null, null, strOrder, null);
    //managedQuery(CallLog.Calls.CONTENT_URI,null,null,null,strOrder);
    int phName = cursor.getColumnIndex(CallLog.Calls.CACHED_NAME);
    int phNumber = cursor.getColumnIndex(CallLog.Calls.NUMBER);
    int phType = cursor.getColumnIndex(CallLog.Calls.TYPE);
    int phDate = cursor.getColumnIndex(CallLog.Calls.DATE);
    int phDuration = cursor.getColumnIndex(CallLog.Calls.DURATION);
    while (cursor.moveToNext()) {
        String name = cursor.getString(phName);
        String number = cursor.getString(phNumber).toString();
        String date = cursor.getString(phDate);
        Date callDate = new Date(Long.valueOf(date));
        String duration = cursor.getString(phDuration);
        String type = cursor.getString(phType);
        int dircode = Integer.parseInt(type);
        //Log.e(String.valueOf(getActivity()),"Values :" +temp);
        if(dircode == 1){
            logList = new CallList();
            callList.add(number); //getting java.lang.string error here
        }
        RecyclerAdapter1 recyclerAdapter1 = new RecyclerAdapter1(callList,getContext());
        recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
        recyclerView.setAdapter(recyclerAdapter1);
    }
    cursor.close();
    //callList.add(logList);
}
}

您要将number String添加到callList ArrayList<CallList>。如果您只关心号码，请将其更改为ArrayList<String>，或callList.add(logList) logList是CallList对象

如何使用片段在回收站视图中显示已拨电话列表？
