如何在android中获取所有发件箱短信和彩信？

我可以获取传出的短信或彩信，但无法获取最新的短信或彩信

        Uri draftURI = Uri.parse("content://sms/sent");

        // List required columns
        String[] reqCols = new String[]{"_id", "address", "body"};

        // Get Content Resolver object, which will deal with Content Provider
        ContentResolver cr = getContentResolver();

        // Fetch Sent SMS Message from Built-in Content Provider
        Cursor c = cr.query(draftURI, reqCols, null, null, null);

我甚至使用了

uridrafturi=Uri.parse（“content://sms");但没有帮助。
检查此项

Uri sentURI = Uri.parse("content://sms/sent");
String[] reqCols = new String[] { "_id", "address", "body" };
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(sentURI, reqCols, null, null, null);

if (cursor.moveToFirst()) { 
    do {
       String msgData = "";
       for(int idx=0;idx<cursor.getColumnCount();idx++)
       {
           msgData += " " + cursor.getColumnName(idx) + ":" + cursor.getString(idx);
       }
       Log.d("Msg",msgData);
    } while (cursor.moveToNext());
}

urisenturi=Uri.parse（“content://sms/sent");
String[]reqCols=新字符串[]{“\u id”，“address”，“body”}；
ContentResolver cr=getContentResolver（）；
Cursor Cursor=cr.query（sentURI，reqCols，null，null，null）；
if（cursor.moveToFirst（））{
做{
字符串msgData=“”；
对于（int-idx=0；idx
