如何在 Android 中获得 MMS 收件箱和已发送箱的准确计数?
Uri mmsInboxUri = Uri.parse("content://mms/inbox");
Cursor mmsInboxCursor = getContentResolver().query(mmsInboxUri ,new String[] {"_id","ct_t"}, null, null, null);
int count = mmsInboxCursor.getCount();
if (mmsInboxCursor != null)
{
if (mmsInboxCursor.moveToFirst())
{
coloumns = mmsInboxCursor.getColumnNames();
//String subject = mmsInboxCursor.getString(mmsInboxCursor.getColumnIndex("sub"));
String string = mmsInboxCursor.getString(1);
if ("application/vnd.wap.multipart.related".equals(string))
