Android 收到带有姓名或地址的短信对话

Question

我正在开发一个 SMS 程序，我想进行对话。
我写了下面的代码，它工作正常，但我想知道它是否可以更有效

这是为了获取对话线程

       Uri SMS_INBOX = Uri.parse("content://sms/conversations/");
    Cursor c = getContentResolver().query(SMS_INBOX, null, null, null, "date desc");

        startManagingCursor(c);
        String[] count = new String[c.getCount()];
        String[] snippet = new String[c.getCount()];
        String[] thread_id = new String[c.getCount()];

        c.moveToFirst(); 
        for (int i = 0; i < c.getCount(); i++) {
            count[i] = c.getString(c.getColumnIndexOrThrow("msg_count"))
                    .toString();
            thread_id[i] = c.getString(c.getColumnIndexOrThrow("thread_id"))
                    .toString();
            snippet[i] = c.getString(c.getColumnIndexOrThrow("snippet"))
                    .toString();
            //Toast.makeText(getApplicationContext(), count[i] + " - " + thread_id[i]+" - "+snippet[i] , Toast.LENGTH_LONG).show();
            c.moveToNext();
        }
        c.close();

根据对话线程获取地址

    for(int ad = 0; ad < thread_id.length ; ad++)
    {
    Uri uri = Uri.parse("content://sms/inbox");
    String where = "thread_id="+thread_id[ad]; 
    Cursor mycursor= getContentResolver().query(uri, null, where ,null,null); 
    startManagingCursor(mycursor);

    String[] number = new String[mycursor.getCount()];


    if(mycursor.moveToFirst()){
            for(int i=0;i<mycursor.getCount();i++){
                    number[i]=mycursor.getString(mycursor.getColumnIndexOrThrow("address")).toString();

                    mycursor.moveToNext();
            }
    }
    mycursor.close();

最后检查地址(如果在联系人列表中)并添加到列表中

     for(int i =0 ; i < numaralar.length ;i++)
    {


    String a = numaralar[i].substring(0,1);



    if(!a.equals("+")){ kisiismi = numaralar[i]; }


    ContentResolver localContentResolver = getApplicationContext().getContentResolver();
       Cursor contactLookupCursor =  
        localContentResolver.query(
                 Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, 
                 Uri.encode(numaralar[i])), 
                 new String[] {PhoneLookup.DISPLAY_NAME, PhoneLookup._ID}, 
                 null, 
                 null, 
                 null);
        try {
        while(contactLookupCursor.moveToNext()){
             String contactName = contactLookupCursor.getString(contactLookupCursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME));
             kisiismi = contactName;
         }
        }catch (Exception e) {
         kisiismi = numaralar[i].toString(); 

        }
          finally {
              //Toast.makeText(getApplicationContext(), ad + kisiismi + " " + count[ad], Toast.LENGTH_LONG).show();
              myArr.add(kisiismi);
              contactLookupCursor.close();
         }

    }    

有什么方法可以让这个过程更简单吗？

由于它是一个简单的 SQLite 查询，并且可以以类似的方式访问联系人提供程序，因此您应该尝试通过数字、时间戳和 thrad_id 进行分组，然后将结果与查询匹配以在 SQL 中完成工作联系人提供者(也通过 SQLite)

该文档对所有可用列进行了很好的描述。 https://developer.android.com/reference/android/provider/ContactsContract.PhoneLookupColumns.html
