android– 当使用alertdialog builder的setCursor方法显示数据库中的项列表时,如何添加多个列？

概述嗨我使用以下代码构建了一个对话框,可以从我的通话记录中选择一个联系人,但它只显示每个项目中的电话号码.如何更改它以在每个项目中显示“联系人姓名”“电话号码”？我试过但似乎builder.setCursor()方法只允许我添加一列,我怎么能添加多个列？谢谢！publicclassMainActivityexte

我试过但似乎builder.setCursor()方法只允许我添加一列,我怎么能添加多个列？谢谢！

public class MainActivity extends Activity {    @OverrIDepublic voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.activity_main);    button btnPick = (button) findVIEwByID(R.ID.btnPick);    btnPick.setonClickListener(new OnClickListener() {        public voID onClick(VIEw v) {            String[] strFIElds = { androID.provIDer.CallLog.Calls._ID,                    androID.provIDer.CallLog.Calls.NUMBER,                    androID.provIDer.CallLog.Calls.CACHED_name, };            String strOrder = androID.provIDer.CallLog.Calls.DATE + " DESC";            final Cursor cursorCall = getContentResolver().query(                    androID.provIDer.CallLog.Calls.CONTENT_URI, strFIElds,                    null, null, strOrder);            AlertDialog.Builder builder = new AlertDialog.Builder(                    MainActivity.this);            builder.setTitle("Select recent contact");            androID.content.DialogInterface.OnClickListener Listener = new DialogInterface.OnClickListener() {                public voID onClick(DialogInterface dialogInterface,                        int item) {                    cursorCall.movetoposition(item);                    Toast.makeText(                            MainActivity.this,                            cursorCall.getString(cursorCall                                    .getColumnIndex(androID.provIDer.CallLog.Calls.NUMBER)),                            Toast.LENGTH_LONG).show();                    cursorCall.close();                    return;                }            };            builder.setCursor(cursorCall, Listener,                    androID.provIDer.CallLog.Calls.NUMBER);            builder.create().show();        }    });}

}

解决方法:

这是我的解决方案.您可以修改和修改它.

public voID getCallLog() {    String[] callLogFIElds = { CallLog.Calls._ID,            CallLog.Calls.NUMBER,            CallLog.Calls.CACHED_name,            CallLog.Calls.DATE};    String ORDER = CallLog.Calls.DATE + " DESC";    String WHERE = CallLog.Calls._ID + " IN (SELECT " + CallLog.Calls._ID + " FROM calls GROUP BY " + CallLog.Calls.NUMBER + ")";    Cursor cursor = getContentResolver().query(CallLog.Calls.CONTENT_URI, callLogFIElds, WHERE, null, ORDER);    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);    if(cursor == null || !cursor.movetoFirst()) return;    final List<Map<String, String>> data = new ArrayList<>();    do    {        long time = cursor.getLong(cursor.getColumnIndex(CallLog.Calls.DATE));        SimpleDateFormat sdf = new SimpleDateFormat("dd.MM.yyyy HH:mm", Locale.getDefault());        Date resultdate = new Date(time);        String date = sdf.format(resultdate);        String number = cursor.getString(cursor.getColumnIndex(CallLog.Calls.NUMBER));        String name = cursor.getString(cursor.getColumnIndex(CallLog.Calls.CACHED_name));        Map<String, String> map = new HashMap<>(4);        map.put("number", number);        map.put("name", name);        map.put("visible_name", name == null ? number : name);        map.put("date", date);        data.add(map);    } while (cursor.movetoNext());    if(!cursor.isClosed()) cursor.close();    DialogInterface.OnClickListener Listener = new DialogInterface.OnClickListener() {        public voID onClick(DialogInterface dialogInterface, int item) {            String number = data.get(item).get("number");            Log.v("dva.re.number", number);        }    };    SimpleAdapter adapter = new SimpleAdapter(this, data,            androID.R.layout.simple_List_item_2,            new String[] {"visible_name", "date"},            new int[] {androID.R.ID.text1,                    androID.R.ID.text2,            });    dialogBuilder.setAdapter(adapter, Listener);    dialogBuilder.setTitle("Choose from Call Log");    dialogBuilder.create().show();}
