extends another activity class and reuse listener codes to views such as buttons etc

Question

I have created an activity called ButtonActivity that has a lot of buttons and listeners. I want to create another activity TwoButtonsActivity to extend ButtonActivity so that the listeners I created can be resused. TwoButtonsActivity is similar to ButtonActivity but with small changes. Is this possible?

When I execute the code, I find that the extended activity do not respond to button click.

Here is the base activity:

public class ButtonActivity extends Activity {
int count = 0; 
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final Button button = (Button) findViewById(R.id.button);
    button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            button.setText("Got Pressed:" + ++count);
            }
    });
}

}

Below is the extends Activity:

public class TwoButtonsActivity  extends ButtonActivity {


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);




}

}

Answer 1

you can have a activity with listeners same below

  public class ButtonActivity extends Activity {
    int count = 0; 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.main);

    }
    public void mylistener1(View v)
    {
    switch(v.getid()){
    case R.id.button:{
    //do somthings
    }break;
}}

public class TwoButtonsActivity  extends ButtonActivity {


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);




}

}

and in layout of TwoButtonsActivity(main) you set in tag of your button android:onclick="mylistener1" and you should set to any button or view that you want it use this listener
