Android - สอบถามเรื่องการเลือกรูปจาก Gallery แล้วส่งรูปภาพข้าม intent ภาพในการกดปุ่มครั้งเดียวครับ

private static int RESULT_LOAD_IMAGE = 1;
	Bitmap temp;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
		setContentView(R.layout.activity_main);
		
		Button gal = (Button)findViewById(R.id.bgal);
		
		gal.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				Intent i = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                startActivityForResult(i, RESULT_LOAD_IMAGE);
                
                Intent intent = new Intent(getApplicationContext(), Gallery.class);
                intent.putExtra("BitmapImage", temp);
    			startActivity(intent);
			}
		});
	}

	@Override
    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();
            
            temp =  BitmapFactory.decodeFile(picturePath);
        }
     
     
    }
