查询无法获取彩信

Question

我正在实施此处讨论的方法How to Read MMS Data in Android。以下是代码段：

ContentResolver contentResolver = getContentResolver();
final String[] projection = new String[]{"*"};
Uri uri = Uri.parse("content://mms-sms/conversations/");
Cursor query = contentResolver.query(uri, projection, null, null, null);

当我尝试通过光标获取数据时，我没有获得MMS消息的ID。我只获取短信的ID。

Answer 1

将您的代码更改为：

ContentResolver contentResolver = getContentResolver();

final String[] projection = new String[]{"*"};

Uri MMSSMS_FULL_CONVERSATION_URI = Uri.parse("content://mms-sms/conversations");  

Uri uri  = MMSSMS_FULL_CONVERSATION_URI.buildUpon().  
     appendQueryParameter("simple", "true").build(); 

Cursor query = contentResolver.query(uri, projection, null, null, null);

Answer 2

我的代码是对的。它只需要这段代码来获取消息的id

cursor.moveToFirst();
String address = cursor.getString(cursor.getColumnIndex("_id"));
