android - 从电话号码中获取短信/彩信 thread_id

Question

我需要获取 mms-sms/conversations Android 内容提供商的 thread_id，这是我目前所做的:

    public long findThreadIdFromPhoneNumber(Context context, PhoneNumber phoneNumber) {
    Uri.Builder uriBuilder = Uri.withAppendedPath(Uri.parse(CONTENT_SMSMMS+"/"), "threadID").buildUpon();
    // phoneNumber.msisdn() return the String phone number 
    uriBuilder.appendQueryParameter("recipient", phoneNumber.msisdn());

    long threadId = -1L;
    Cursor cursor = null;
    try {
        cursor = context.getContentResolver().query(
                uriBuilder.build(),
                new String[] { Contacts._ID },
                null, null, null);
        if (cursor != null && cursor.moveToFirst()) {
            threadId = cursor.getLong(0);
        }
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
    return threadId;
}

问题是这段代码在内容提供者中创建了新的线程，我不需要它，我只需要在 session 存在时返回 thread_id，如果不存在则返回 -1存在。

我也试过这段代码:

    public long findThreadIdFromPhoneNumber(Context context, PhoneNumber phoneNumber) {
    long threadId = -1L;
    Cursor cursor = null;
    try {
        if (context==null || context.getContentResolver()==null || phoneNumber==null || phoneNumber.msisdn()==null) 
            return threadId; 
        cursor = context.getContentResolver().query(
            Uri.parse(CONTENT_SMSMMS_CONVERSATIONS), 
            // phoneNumber.msisdn() return the String phone number 
            null, "address='"+phoneNumber.msisdn()+"' ",  
            null, null
        );
        if (cursor != null && cursor.moveToFirst()) {
            if (cursor.getColumnIndex("thread_id")>=0)
                threadId = cursor.getLong(cursor.getColumnIndex("thread_id"));
        }
    } catch (Exception e) {
        e.printStackTrace();
        String number = (phoneNumber!=null && phoneNumber.msisdn()!=null) ? phoneNumber.msisdn() : "";
        Logcat.e("Error during findThreadIdFromPhoneNumber for "+number+": "+e.getMessage(), e);
        return threadId; 
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
    return threadId;
}

但这段代码在某些手机的 ContentResolver 中给了我一个外部 NullPointerException，它在其他手机中有效:

java.lang.NullPointerException

Answer 1

使用这个uri来获取

ContentResolver cr = context.getContentResolver();
    Cursor pCur = cr.query(
            Uri.parse("content://mms-sms/canonical-addresses"), new String[]{"_id"},
            "address" + " = ?",
            new String[]{your_address}, null);

    String thread_id = null;

    if (pCur != null) {
        if (pCur.getCount() != 0) {
            pCur.moveToNext();
            thread_id = pCur.getString(pCur.getColumnIndex("_id"));
        }
        pCur.close();
    }
