Question

我想查询CallLog数据库并根据指定的日期返回一些调用。例如，我希望能够从给定日期获取数据，即9月1日至今。

我通过调用：

查询数据库

        Date d = new Date();


    String strOrder = android.provider.CallLog.Calls.DATE + " > " + d.toString();
    /* Query the CallLog Content Provider */
 /*Cursor managedCursor = managedQuery(CallLog.Calls.CONTENT_URI, null,
           null, null, strOrder);*/
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_CALL_LOG) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling
        Log.d(TAG, "Did not have permissions.");
        return;
    }
    Cursor managedCursor = this.getContentResolver().query(CallLog.Calls.CONTENT_URI, null,
            null, null, strOrder);

这给了我一个错误，但没有启动活动。

由于您没有指定您收到的错误，我只能给您一个在我的代码中有效的示例：

String query = "( " + CallLog.Calls.DATE + " >= " + from +
            " AND " + CallLog.Calls.DATE + " <= " + to + ")";

Cursor callsCursor = context.getContentResolver().query(
                                CallLog.Calls.CONTENT_URI, 
                                null, 
                                query, 
                                null, 
                                null, 
                                CallLog.Calls.DATE + " DESC");


if (callsCursor != null) {
    while (callsCursor.moveToNext()) {
         String number = callsCursor.getString(callsCursor.getColumnIndex(CallLog.Calls.NUMBER));
         int type = callsCursor.getInt(callsCursor.getColumnIndex(CallLog.Calls.TYPE));
         long date = callsCursor.getLong(callsCursor.getColumnIndex(CallLog.Calls.DATE));
         int duration = callsCursor.getInt(callsCursor.getColumnIndex(CallLog.Calls.DURATION));

         // the rest of your code goes here
    }
}

希望有所帮助
