Why method in Runnable works only one time?

Question

As you can see method refreshProgressBars() works only one time, although Toast created without interruption. How it possible?!

 bREnemyRegeneration = new Runnable() {
            @Override
            public void run() {
                refreshProgressBars(); //method works only 1 time
                Toast.makeText( //works always
                      BattleActivity.this, 
                      "THIS TOAST WILL BE SHOWN", 
                      Toast.LENGTH_SHORT).show();
                bHandlerTimers.postDelayed(bREnemyRegeneration, 3000); //start new iteration of this Runnable
            }
        };

Just in case method refreshProgressBars():

public void refreshProgressBars(){
    checkDeath();
    if (bHealthsBar.getLayoutParams().width < 30) bHealthsBar.getLayoutParams().width = 0;
    else bHealthsBar.getLayoutParams().width = (int) (PB_EN_HP_WIDTH * bEnemy.getHealth(false) / bEnemy.getHealth(true));
}

Runnable calls as follows:

bHandlerTimers = new Handler();
bHandlerTimers.post(bREnemyRegeneration);

Answer 1

I edit method refreshProgressBar() as follows: Instead bHealthsBar.getLayoutParams().width = bWidth I used bHealthsBar.setLayoutParams(new RelativeLayout.LayoutParams(bWidth, bHealthsBar.getLayoutParams().height));

And... all works! Question is closed.
