从类传递上下文扩展线程

Question

Before, I was using kelas1 extends Service , and my code worked for read inbox. But I don't know how to get this to work if my class is using kelas1 extends thread .

sms.inbox(kelas1.this,localDataOutputStream);

And this is my code:

kelas1.java

public class kelas1 extends Thread {
public void run() {
    //code
    while (true) {

        charsRead = in.read(buffer);
        if (charsRead != 1) {
            String message = new String(buffer).substring(0, charsRead).replace(System.getProperty("line.separator"),"");
            Log.d("wew", message);

                // this is my problem
            sms.inbox(kelas1.this,localDataOutputStream);
    }

}

readsms.java

public class readsms {

    public void inbox(Context context, DataOutputStream outstr) throws IOException{
        Uri uriSMSURI = Uri.parse("content://sms/inbox");

          Cursor cur = context.getContentResolver().query(uriSMSURI, null, null, null,null);
          String sms = "";
          int body = cur.getColumnIndex("body");
          while (cur.moveToNext()) {
              sms += "Dari :" + cur.getString(2) + " : " + cur.getString(body);         
          }
          Log.d("wew", sms);
          sms = sms + "\nbaca sms selesai";
          outstr.writeBytes(sms);
    }
}

You need a context of activity class, so you need one constructor in kelas1

Context context;

public kelas1(Context context)
{
   this.context = context;
}

then in your code you must use this context like:

     sms.inbox(context,localDataOutputStream);

Change your code up top to something like:

final Context context;
public class kelas1 extends Activity {

   public kelas1(Context context)
    {
       this.context = context;
       call_thread();   
    }

public void call_thread(){
        new Thread(new Runnable(){
         public void run() {
            while (true) {
                charsRead = in.read(buffer);
                if (charsRead != 1) {
                    String message = new String(buffer).substring(0, charsRead).replace(System.getProperty("line.separator"),"");
                    Log.d("wew", message);

                    // this is my problem
                        sms.inbox(this.context,localDataOutputStream);
                }
              }
           }).start();

        }
    }
