启用复选框以在 android 中停用声音

Question

我正在 android 中创建一个简单的游戏，当我选择应用程序并且声音开始时，我想用复选框停用声音，它可以停用并且显示音乐已停用但音乐仍在进行中，我们将不胜感激。

public class Setting extends Activity {
 public static MediaPlayer Sounds;
private CheckBox sound;
private Boolean isChecked = false;
public void Is_checked() {
 if (isChecked) {

    Sounds.start();

    Toast.makeText(Setting.this, "Sound is activated ",
            Toast.LENGTH_LONG).show();
  }

   else {
    Sounds.stop();
    Toast.makeText(Setting.this, "Sound is deactivated ",
            Toast.LENGTH_LONG).show();
 }
 }

 public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.setting);
Sounds = MediaPlayer.create(this, R.raw.backmusic);
isChecked = false;
addListenerOnsound();

 }

protected void onStart() {
super.onStart();
isChecked = false;
addListenerOnsound();
   }

    private void save(final boolean isChecked) {
  SharedPreferences sharedPreferences =    getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("check", isChecked);
editor.commit();
}

     private boolean load() {
SharedPreferences sharedPreferences = getPreferences(Context.MODE_PRIVATE);
return sharedPreferences.getBoolean("check", false);
  }

   protected void onReStart() {
    super.onRestart();
    sound.setChecked(load());
 }

     @Override
       void onPause() {
             super.onPause();
       save(sound.isChecked());
        }

          @Override
        public void onResume() {
         super.onResume();
              sound.setChecked(load());
           }

         public void addListenerOnsound() {

     sound = (CheckBox) findViewById(R.id.sound);

   sound.setOnClickListener(new OnClickListener() {

        @Override
       public void onClick(View v) {

          if (((CheckBox) v).isChecked()) {
            isChecked = true;
            Is_checked();

           }

          if (!((CheckBox) v).isChecked()) {
            isChecked = false;
            Is_checked();

        }}  });}}

如果您想恢复音频，只需使用

Sounds.pause();

而不是

Sounds.stop()

但如果您希望它从头开始，请执行此操作。

public void Is_checked() {
        if (isChecked) {

            Sounds.start();

            Toast.makeText(this, "Sound is activated ",
                    Toast.LENGTH_LONG).show();
        }

        else {
            Sounds.stop();
            Sounds = MediaPlayer.create(this, R.raw.backmusic);

            Toast.makeText(this, "Sound is deactivated ",
                    Toast.LENGTH_LONG).show();
        }
    }
