I am building a soundboard with about 40 sounds using a map. (Previous thread)
Does anyone know a good way to pause restart Mediaplayer if the app is moved to the background (incoming call or anything like that)? I'm still very new at this so it is probably something super simple. Thanks anyone who can help.
Map map = new
HashMap();
map.put(R.id.button1, R.raw.sound1);
map.put(R.id.button2, R.raw.sound2);
...
and then iterate:
for (Map.Entry entry : map.entrySet()) {
final MediaPlayer sound = MediaPlayer.create(entry.getValue()); Button button = (ImageButton) findViewById(entry.getKey()); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { sound.start(); } });}
回答1:
I assume you don't want to play all sounds together, so you can declare the mediaplayer object outside the loop and then you don't need to know which file is being played. You can use sound.pause(); sound.stop(); or sound.reset(); (depends on the action you want to preform) I suggest you look at the android docs to see how to implement it properly.
If you want to create mediaplayer for each file which I doubt you want, save the mediaplayers in a map / list and pause / reset them in loop during onPause().
回答2:
Override Activity.onPause(). This is called whenever your app goes to the background, Home button or back button or incoming call or magic thunderclouds of doom.
