Try with something like this..

Java

private Button btn1
private Button btn2;
@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.yourPage);

    btn1=(Button)findViewById(R.id.btn_1);
    btn2=(Button)findViewById(R.id.btn_2);

    btn1.setOnClickListener(this);
    btn2.setOnClickListener(this);

}
public void onClick(View v) {
    // TODO Auto-generated method stub

    switch (v.getId()) {

    case R.id.btn_1:
                   //do your button 1 work here
        break;
    case R.id.btn_2:
                   //do your button 2 work here
        break;
     }

Thanks, but your code works ONLY if all buttons are in the same UI(activity), so it's doesn't work in my case(multi-UI), unfortunately, I don't know why...
