Problem with ImageButton.setVisibility()
- by Luis Lopez
Hello guys!
I'm having a problem when setting the visibility of two image buttons one on top of the other. The idea is to implement a play/pause control. The problem is that the only part where setting the visibility actually works is in the click listeners of the buttons. If I try to change it somewhere else nothing happens. Any idea why is this happening?
Thanks in advance!
playBtn.setOnClickListener(new OnClickListener() {//PLAY BUTTON LISTENER
public void onClick(View v) {
playBtn.setVisibility(ImageButton.GONE);
pauseBtn.setVisibility(ImageButton.VISIBLE);
mp.start();
}});
pauseBtn.setOnClickListener(new OnClickListener() {//PAUSE BUTTON LISTENER
public void onClick(View v) {
pauseBtn.setVisibility(ImageButton.GONE);
playBtn.setVisibility(ImageButton.VISIBLE);
mp.pause();
}});
final class SeekBarTask extends TimerTask {
public SeekBarTask(int duration) {
}
@Override
public void run() {
if(seekBar.getProgress() = mp.getDuration()) {//IF SONG HAS FINISHED...
pauseBtn.setVisibility(ImageButton.GONE);//THESE ONES
playBtn.setVisibility(ImageButton.VISIBLE);//DOESN'T WORK
mp.stop();
}
else {
seekBar.incrementProgressBy(100);
}
}
}
