Voir image différente sur la même Gridview Android

Question

Je veux montrer autre image dans la présentation de la grille MainActivity.java

b1.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        if(isReadStorageAllowed()){ 
         Intent intent = new Intent(MainActivity.this, GridActivity.class); 
intent.putExtra("firstKeyName","FirstKeyValue"); 
intent.putExtra("secondKeyName","SecondKeyValue"); 
         MainActivity.this.startActivity(intent); 

       } 
      }); 

Je veux montrer des images dans GridLayout mon GridActivity.java Code est la suivante

Intent intent; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
intent = getIntent(); 
// Get the view from new_activity.xml 
setContentView(R.layout.activity_grid); 


GridView gridview = (GridView) findViewById(R.id.gridview); 
gridview.setAdapter(new ImageAdapter(this)); 

gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
    public void onItemClick(AdapterView<?> parent, 
          View v, int position, long id){ 
    } 
}); 

Et dans ImageAdapter Je veux obtenir l'intention valeur de MainActivity pour l'utiliser dans le filtre en images (autre image vue unique u chanter autre bouton)

de ImageAdapter.java

public class ImageAdapter extends BaseAdapter { 
    private Context mContext; 

    // Constructor 
    public ImageAdapter(Context c) { 
     mContext = c; 
    } 

    public int getCount() { 
     return mThumbIds.length; 
    } 

    public Object getItem(int position) { 
     return null; 
    } 

    public long getItemId(int position) { 
     return 0; 
    } 

    // create a new ImageView for each item referenced by the Adapter 
    public View getView(int position, View convertView, ViewGroup parent) { 
     ImageView imageView; 

     /*if (convertView == null) {*/ 
     imageView = new ImageView(mContext); 
     imageView.setLayoutParams(new GridView.LayoutParams(350, 350)); 
     imageView.setScaleType(ImageView.ScaleType.FIT_START); 
     imageView.setPadding(8, 8, 8, 8); 
     /*} 
     else 
     { 
      imageView = (ImageView) convertView; 
     }*/ 
     imageView.setImageResource(mThumbIds[position]); 
     return imageView; 
    } 

    // Keep all Images in array 
    public Integer[] mThumbIds = { 
      R.drawable.b1, R.drawable.b2, R.drawable.b3, 
      R.drawable.b4, R.drawable.b5, R.drawable.b6, 
      R.drawable.b7, R.drawable.b8, R.drawable.b9, 
      R.drawable.b10, R.drawable.b11, R.drawable.b12, 
    };

public class ImageAdapter extends BaseAdapter { 
    private Context mContext; 

    // Constructor 
    public ImageAdapter(Context c) { 
     mContext = c; 
    } 

    public int getCount() { 
     return mThumbIds.length; 
    } 

    @Override 
    public Object getItem(int i) { 
     return mThumbIds[i]; 
    } 

    @Override 
    public long getItemId(int i) { 
     return mThumbIds[i]; 
    } 


    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     ImageView imageView; 

    /*if (convertView == null) {*/ 
     imageView = new ImageView(mContext); 
     imageView.setLayoutParams(new GridView.LayoutParams(350, 350)); 
     imageView.setScaleType(ImageView.ScaleType.FIT_START); 
     imageView.setPadding(8, 8, 8, 8); 
    /*} 
    else 
    { 
     imageView = (ImageView) convertView; 
    }*/ 
     imageView.setImageResource(mThumbIds[position]); 
     return imageView; 
    } 

    // Keep all Images in array 
    public Integer[] mThumbIds = { 
      R.drawable.b1, R.drawable.b2, R.drawable.b3, 
      R.drawable.b4, R.drawable.b5, R.drawable.b6, 
      R.drawable.b7, R.drawable.b8, R.drawable.b9, 
      R.drawable.b10, R.drawable.b11, R.drawable.b12,
