{

            @Override
            public void onClick(View v) {
                    count++;
                   setTimertext(count);

        }
        });

public void setTimertext(String strValue) {         
        runOnUiThread(new Runnable() {
            public void run() {

                txt.setText(String.valueOf(strValue));    
            }
