        }
        break;

    case 100:
        if(score == 100){
            listtt.set(0, true);
            pos=100;
        }
        break;
case 101:
    if(score == 101){

public void setvisibility(int id){

if(id==100){
    tv_fav7.setVisibility(View.VISIBLE);
}else {tv_fav7.setVisibility(View.GONE);}

if(id==101){
    tv_fav6.setVisibility(View.VISIBLE);
}else {tv_fav6.setVisibility(View.GONE);}

First you have to call the setvisibility method somewhere.

Second, and more important, you have to notice, that the values that you set into your listtt are never saved anywhere. They won't exist anymore after going to another activity, if you don't save them (manually)!

You can do that e.g. by saving it to the sharedPreferences:

In your onDestroy method iterate through your listtt and put all the values to the sharedPreferences via a SharedPreferences.Editor.

From your code I'd suggest saving it to the sharedpreferences. – Andi May 02 '15 at 14:26
i stored in arrayelist with this command : listtt.set(1, true); – farzad226 May 02 '15 at 14:28
yes, but this arraylist isn't saved anywhere! You have to put it's values somewhere, to be able to read them, when you need them! – Andi May 02 '15 at 14:29
how i can do it ? (means saved arraylist) and access it later? tnx – farzad226 May 02 '15 at 14:34

Just use

'textView.setVisibilty(View.VISIBLE)'

for all the textViews back to back it will appear that they come on at the same time to the user. Do the same for gone.

You need to send an intent to another class and use this method in the oncreate of that class – Taylor Courtney May 02 '15 at 14:11
Or if you want to stay in that class just do it in the buttons on click listener – Taylor Courtney May 02 '15 at 14:12
i user sharedprefrences and success retreive my value , my problem in show textview together – farzad226 May 02 '15 at 14:24
So setting the visibility for each one one by one is not working? Are you sure you defined the textViews. – Taylor Courtney May 02 '15 at 14:28
its work on bye one, but i want pervious textview stay visible but it not – farzad226 May 02 '15 at 14:29
