show-hide bouton à bascule pour la mise en page dans Android

Question

Je me demandais pourquoi un bouton je fait pour afficher/cacher mes mises en page ne fonctionne qu'une fois, à savoir d'abord mes mises en page sont GONE, puis lorsque je clique sur un bouton, ils sont VISIBLE, mais plus tard, quand je clique sur le même bouton, leur point de vue n'est pas remis à GONE.

/** 
* Method to show/hide buttons, on button click. 
* @param v 
*/ 
public void hideOrDisplayOptionIconsButton(View v) 
{ 
    // Hide layouts if VISIBLE 
    if(mMapViewsButtonsLinearLayout.getVisibility() == View.VISIBLE 
     && mLocationButtonsLinearLayout.getVisibility() == View.VISIBLE) 
    { 
     mMapViewsButtonsLinearLayout.setVisibility(View.GONE); 
     mLocationButtonsLinearLayout.setVisibility(View.GONE); 
    } 
    // Show layouts if they're not VISIBLE 
    else 
    { 
     mMapViewsButtonsLinearLayout.setVisibility(View.VISIBLE); 
     mLocationButtonsLinearLayout.setVisibility(View.VISIBLE); 
    } 
}

Voici un échantillon qui devrait travailler pour vous

import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.LinearLayout; 

public class MainActivity extends Activity { 

    private LinearLayout mMapViewsButtonsLinearLayout=null; 
    private LinearLayout mLocationButtonsLinearLayout=null; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     mMapViewsButtonsLinearLayout= (LinearLayout) findViewById(R.id.mMapViewsButtonsLinearLayout); 
     mLocationButtonsLinearLayout= (LinearLayout) findViewById(R.id.mLocationButtonsLinearLayout); 

    } 

    public void hideOrDisplayOptionIconsButton(View v) 
    { 
     // Hide layouts if VISIBLE 
     if(mMapViewsButtonsLinearLayout.getVisibility() == View.VISIBLE 
       && mLocationButtonsLinearLayout.getVisibility() == View.VISIBLE) 
     { 
      mMapViewsButtonsLinearLayout.setVisibility(View.GONE); 
      mLocationButtonsLinearLayout.setVisibility(View.GONE); 
     } 
     // Show layouts if they're not VISIBLE 
     else 
     { 
      mMapViewsButtonsLinearLayout.setVisibility(View.VISIBLE); 
      mLocationButtonsLinearLayout.setVisibility(View.VISIBLE); 
     } 
    } 
} 

Voici la mise en page

<?xml version="1.0" encoding="utf-8"?>

     <Button

    </LinearLayout> 

    <LinearLayout 
     android:orientation="horizontal" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content">
