setVisibility（View.INVISIBLE）在onResume（）方法中不起作用

Question

Started an Activity B from Activity A without finishing A. if the Activity B is finished,i have written a method inside onResume() of Activity A to make an ImageView invisible. But this is not working. Code is given below.

public void onResume()
{
    if(preferenceUtil.getMUSIC_ONOFF()==0) {
        try {
            player.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    giftbutton.setEnabled(true);
    giftbutton.setClickable(true);

    checkUnlockedStory();
    super.onResume();
}

  public void checkUnlockedStory()
        {
             if(preferenceUtil.getOVERALL_STARS()>=24)
            {                 
                    giftbutton.setImageResource(R.drawable.gift);
                    giftbutton_count.setVisibility(View.INVISIBLE);                  

            }
   }

Answer 1

make sure you have override onResume method:

@Override
protected void OnResume()
{
super.onResume();
//Type your code here
}

Answer 2

尝试这个

giftbutton_count.setVisibility(View.GONE);

Answer 3

I think you are using wrong id ,might be missing this

giftbutton.setVisibility(View.INVISIBLE);

Answer 4

For future googlers, you might need to do yourView.clearAnimation(); after yourView.setVisibility(View.GONE); , since your view might already start animation once which causes extra layer still remains visible.
