        setContentView(R.layout.main);

        tv = (TextView)findViewById(R.id.myid);
        threadt=newthread();
        t.start();
    }

publicclassthreadextendsThread {
    publicvoidrun() {
        while (response < 100) {
            handler.sendEmptyMessage(0);
            response++;
            try {
                sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    privateHandlerhandler=newHandler() {
        publicvoidhandleMessage(Message msg) {

            tv.setText("helloworld " + response);
        }
    };

Solution 2:

all the changes to the UI Part should be done on the UIThread, you should use something like post, or runOnUithread functions to update UI.
