在活动之间传递int变量

Question

我无法在两个活动之间传递int变量，它总是传递0 ...这是我的代码，请帮助....

发件人类：

Intent myIntent = new Intent(Senderclass.this, Receiverclass.class);

int  b = 2;
int  bb = 2;
myIntent.putExtra("aaa", b);
myIntent.putExtra("bbb", bb);
startActivity(myIntent);

Reciver Class：

Bundle bundle=getIntent().getExtras();

的onCreate ....

protected void onCreate(Bundle savedInstanceState) 
{ 
    // TODO Auto-generated method stub super.onCreate(savedInstanceState);     
    setContentView(R.layout.on_a_same_device3);
    Bundle bundle=getIntent().getExtras(); 
    if(bundle != null) { 
        aaa = getIntent().getIntExtra("aaa", 9); 
        bbb = getIntent().getIntExtra("bbb", 9);
    }

protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub super.onCreate(savedInstanceState);     
    setContentView(R.layout.on_a_same_device3);
    Bundle bundle=getIntent().getExtras();
    if(bundle != null) { 
        aaa = bundle.getInt("aaa");//I am not using default value.
        bbb = bundle.getInt("bbb", 9);//Using default value.
    }
}
