Android通话记录返回零结果

对于此问题，可以使用以下代码示例来解决：

//在AndroidManifest.xml中添加通话记录读取权限
<uses-permission android:name="android.permission.READ_CALL_LOG" />

//使用以下代码来获取通话记录
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_CALL_LOG) != PackageManager.PERMISSION_GRANTED) {
    return; //需要经过用户授权才能获取通话记录
}
Cursor cursor = getContentResolver().query(CallLog.Calls.CONTENT_URI,
        null, null, null, CallLog.Calls.DATE + " DESC");

//遍历通话记录并显示
if (cursor.moveToFirst()) {
    do {
        String phone = cursor.getString(cursor.getColumnIndex(CallLog.Calls.NUMBER));
        String type = cursor.getString(cursor.getColumnIndex(CallLog.Calls.TYPE));
        String date = cursor.getString(cursor.getColumnIndex(CallLog.Calls.DATE));
        String duration = cursor.getString(cursor.getColumnIndex(CallLog.Calls.DURATION));
        //添加自己的处理逻辑
    } while (cursor.moveToNext());
}
cursor.close();
