Declare Global Variables just after your class declaration at the top:

 private static int RESULT_LOAD_IMAGE = 1;
 private static final int PICK_FROM_GALLERY = 2;
 Bitmap thumbnail = null; 

Call the intent like this: (Your funizone() function)

   public void funzione(){
       Intent in = new   Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                      startActivityForResult(in, RESULT_LOAD_IMAGE);

   }

Handle the result like this: Declare this outside of your onCreate anywhere in the class.

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {  

    super.onActivityResult(requestCode, resultCode, data);     

     if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data){

         Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();
            thumbnail = (BitmapFactory.decodeFile(picturePath));

thumbnail is your picture, now play with it!
