終了ボタン:
ImageView imageAllBack = (ImageView)this.findViewById(R.id.imageAllBack);
imageAllBack.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//mediaPlayer.stop();
if(mediaPlayer != null)
{
mediaPlayer.stop();
mediaPlayer.release();
}
finish();
}
});
MediaPlayer イベント:
@Override
protected void onStop() {
super.onStop();
mediaPlayer.stop();
mediaPlayer.release();
}
@Override
public boolean onTouchEvent(MotionEvent event) {
mediaController.show();
return false;
}
