no keyboard for ID 0 how can i fix it?

Question

I don't know why this happens because my previous code like this was working but when my activity go on this the application will stop no keyboard for id 0.

public class Lesson_p extends Activity implements OnClickListener {
MediaPlayer p, p_sound;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.lesson_p);
    p = MediaPlayer.create(this, R.raw.p);
    p_sound = MediaPlayer.create(this, R.raw.p_sound);

    View p = findViewById(R.id.imageButton_p);
    p.setOnClickListener((OnClickListener)this);

    View p_sound = findViewById(R.id.imageButton_pp);
    p_sound.setOnClickListener((OnClickListener)this);

    Button back = (Button) findViewById(R.id.button_bckp);
    back.setOnClickListener((OnClickListener)this);

    Button next = (Button) findViewById(R.id.button_nxtp);
    next.setOnClickListener((OnClickListener)this);
}

public void onClick(View v) {
    // TODO Auto-generated method stub
     switch(v.getId()){
        case R.id.imageButton_p:
            p.start();
            break;

        case R.id.imageButton_pp:
            p_sound.start();
            break;

        case R.id.button_bckp:
            Intent back = new Intent(this, Example_n.class);
            startActivity(back);
            break;

        case R.id.button_nxtp:
            Intent next = new Intent(this, Example_p.class);
            startActivity(next);
            break;

        }       

}
//@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    p.release();
    p_sound.release();
}
}

yes because when the imagebutton is click the MediaPlayer will start. . — user1632229, Aug 30 '12 at 13:02
