如何保存editText可见性状态（View.GONE）？

Question

I have a problem with editText visibility. In the beginning of my code I've set visibility to GONE

editText.setVisibility(View.GONE);  

This part is fine, it sets my editText to GONE. However if i minimise my app and then summon it again, editText field becomes Visible. I've tried to save View setting with SharedPreferences, but i don't know how to do it right. I am trying to save View with:

myPrefs = getSharedPreferences("save steps", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = myPrefs.edit();
editor.putInt("visibility", editText.getVisibility());
editor.commit();   

And then load data back with:

editText.setVisibility(myPrefs.getInt("visibility", 0)); 

But this approach crashes my app. Maybe there are any suggestions how to solve this?

Answer 1

The reason is simple. When app come back from background, activity restarts (recreate your edittext ).

You can use savedInstanceState or put

@Override
public void onResume(){
    super.onResume();
    edittext.setVisibility(View.GONE);
}

EDIT: Change:

editText.setVisibility(myPrefs.getInt("visibility", 0)); 

to

editText.setVisibility(myPrefs.getInt("visibility", View.GONE)); 

I can't see the entire code, maybe app crash is caused by null pointer exception..
