我正在为 Android 编写游戏。声音问题:菜单2项(soundOn & soundOff)当您在soundOff声音不出现后按下soundon时
public class AudioClip {
float MAX = 500;
float MIN = 0;
protected boolean mPlaying = false;
private boolean mLoop = false;
public AudioClip(Context ctx, int resID) {
name = ctx.getResources().getResourceName(resID);
mPlayer = MediaPlayer.create(ctx, resID);
mPlayer.setVolume(MAX, MAX);
mPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mPlaying = false;
if (ismLoop()) {
System.out.println("AudioClip loop " + name);
mp.start();
}
}
});
}
public synchronized void play() {
if (mPlaying)
return;
if (mPlayer != null) {
mPlaying = true;
mPlayer.start();
}
}
public synchronized void stop() {
try {
setmLoop(false);
if (mPlaying) {
mPlaying = false;
mPlayer.pause();
}
} catch (Exception e) {
System.err.println("AduioClip::stop " + name + " " + e.toString());
}
}
public synchronized void loop() {
setmLoop(true);
mPlaying = true;
mPlayer.start();
}
public void release() {
if (mPlayer != null) {
mPlayer.release();
mPlayer = null;
}
}
boolean sound = b;
public void setSoundOn(boolean sound)
{
this.sound = sound;
}
public boolean isSoundOn()
{
return sound;
}
public boolean ismLoop() {
return mLoop;
}
public void setmLoop(boolean mLoop) {
this.mLoop = mLoop;
}
}
主类所在的Menu方法如何解决问题
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater = this.getMenuInflater();
inflater.inflate(R.menu.menu, menu);
SubMenu subMenuSound = menu.addSubMenu("Sound");
subMenuSound.add(Menu.NONE,IDM_SON,Menu.NONE,"SoundOn");
subMenuSound.add(Menu.NONE,IDM_SOF,Menu.NONE,"SoundOff");
sound = menu.add(0, 2, 0, "FullScreenOff");
this.menu = menu;
return true;
}
enter code here @Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.new_game:
LayoutInflater f = LayoutInflater.from(this);
v = f.inflate(R.layout.main, null);
setContentView(v);
v.setFocusable(true);
v.setFocusableInTouchMode(true);
break;
case IDM_SON :
AudioClip.mPlayer.start();
break;
case IDM_SOF :
if (AudioClip.mPlayer != null) {
AudioClip.mPlayer.stop();
}
break;
return false;
}
}
