Using Switch Statement to Handle Button Clicks

Question

I\'m trying to wrap my head around Views, Listeners etc. I have an Activity with 2 Buttons: buttonplay and buttonstop. My problem is I can\'t wrap my head around the Views

Answer 1

Just change the class (I suppose it's the main Activity) to implement View.OnClickListener and on the onClick method put the general onClick actions you want to put:

public class MediaPlayer extends Activity implements OnClickListener {

@Override
public void onCreate(Bundle savedInstanceState) {
    Button b1 = (Button) findViewById(R.id.buttonplay);       
    b1.setOnClickListener(this);
    //{YOUR APP}
}


@Override
public void onClick(View v) {
    // Perform action on click
    switch(v.getId()) {
    case R.id.buttonplay:
        //Play voicefile
        MediaPlayer.create(getBaseContext(), R.raw.voicefile).start();
        break;
    case R.id.buttonstop:
        //Stop MediaPlayer
        MediaPlayer.create(getBaseContext(), R.raw.voicefile).stop();
        break;
    }

}}

I took it from this video: http://www.youtube.com/watch?v=rm-hNlTD1H0 . It's good for starters.
