Android: How to set Visibility permanently

This is not a duplication from the 'how to setVisibility' questions.

I have an activity 1 and an activity 2, when I start activity 2 I set a layout from Gone to Visible in a Listener and it works, my problem is, when I return to activity 1 and go back into activity 2, the layout's visibility is back to Gone. How do I make the layout stay Visible when I leave it?

Activity2.java:

@Override
 public void onClick(View v) {

        if (FirstLayout.getVisibility() == View.INVISIBLE) {
            FirstLayout.setVisibility(View.VISIBLE);
         }
}

Activity2.xml:

 <LinearLayout
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:visibility="invisible"
      android:id="@+id/oneLayout"
      android:animateLayoutChanges="true"
      android:orientation="vertical">

      <!-- one Button -->
      <!-- one TextView -->   

  </LinearLayout>

As said in comments above, in your Activity2.java:

SharedPreferences sharedPreferences;

and in the onCreate method at Activity2:

 sharedPreferences=getPreferences(Context.MODE_PRIVATE);
 FirstLayout.setVisibility(sharedPreferences.getBoolean("visibility",false));

and then:

 @Override
    public void onClick(View v) {
    if (FirstLayout.getVisibility() == View.INVISIBLE) {
        FirstLayout.setVisibility(View.VISIBLE);
        SharedPreferences.Editor editor=sharedPreferences.edit();
        editor.putBoolean("visibility",true).commit();
     }
}

you can save your last state via following method

boolean mState = false;
final String STATE_VISIBILITY = "state-visibility";

// somewhere in the code assign a value to mState 
// i.e. mState = false (if GONE default) and mState = true (if VISIBLE)

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    // Save the user's current game state
    savedInstanceState.putBoolean(STATE_VISIBILITY, mState);

    // Always call the superclass so it can save the view hierarchy state
    super.onSaveInstanceState(savedInstanceState);
}

and restore

@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
    // Always call the superclass so it can restore the view hierarchy
    super.onRestoreInstanceState(savedInstanceState);

    // Restore state members from saved instance
    mState = savedInstanceState.Boolean(STATE_VISIBILITY);
    view.setVisibility(mState?View.VISIBLE:View.GONE);

    }
