How to implement OnClickListener on Android

Question

I learn from

http://developer.android.com/reference/android/widget/Button.html

that \"instead of applying an OnClickListener to the button

Answer 1

public class start extends Activity implements View.OnClickListener { Button bSMS;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_start);
    bSMS = (Button) findViewById(R.id.button);


    bSMS.setOnClickListener(this);

}

@Override
public void onClick(View arg0) {
    // TODO Auto-generated method stub

    switch (arg0.getId()) {

        case R.id.button:        //"Block SMSs" button pressed
            startActivity(new Intent(this,secret_main.class));
            break;

    }
}

}
