about used value on Progress Bar

I am developing game in android. I want to used to value progress of Progress Bar to do force shot a arrows .And this is my code :

public class TheArrows extends Activity {
    ProgressBar myProgressBar;
    private int myProgress=0;
    private int t=0;

    @Override public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.main);
        myProgressBar=(ProgressBar)findViewById(R.id.progressbar_Horizontal);
        app.quabongchuyendong.QuaBongView quaBongView=(app.quabongchuyendong.QuaBongView) findViewById(R.id.qua_bong);
        quaBongView.setOnTouchListener(new OnTouchListener() {
            @Override public boolean onTouch(View view, MotionEvent event) {
                if(event.getAction()==MotionEvent.ACTION_DOWN){ t=1; }
                if(event.getAction()==MotionEvent.ACTION_MOVE){ t=1; }
                if(event.getAction()==MotionEvent.ACTION_UP){ t=0; }
                return false;
            }
        });
        new Thread(myThread).start();
    }

    private Runnable myThread = new Runnable(){
        @Override public void run() {
            // TODO Auto-generated method stub 
            while (myProgress<100){
                try{
                    myHandle.sendMessage(myHandle.obtainMessage());
                    Thread.sleep(100);
                } catch(Throwable t){ }
            }
        }

       Handler myHandle = new Handler(){
            @Override public void handleMessage(Message msg) {
                if(t==1) myProgress++;
                myProgressBar.setProgress(myProgress);
            } 
        };
    };

    public int progressValue(){
        return myProgress;
    }
}

Although I have myProgress++; why myProgress in progressValue() doesn't change? Please help me.

Try This :

 @Override public boolean onTouch(View view, MotionEvent event) {
                if(event.getAction()==MotionEvent.ACTION_DOWN){ t=1; }
                else if(event.getAction()==MotionEvent.ACTION_MOVE){ t=1; }
                else if(event.getAction()==MotionEvent.ACTION_UP){ t=0; }  
     new Thread(myThread).start(); 
                return false;
            }
        });

and Remove if(t==1) condition in handler Handler 

   myHandle = new Handler(){
    @Override public void handleMessage(Message msg) {
        myProgress++;
        myProgressBar.setProgress(myProgress);
    } 
};

};
