Android 按钮在单击一次后被禁用。我想重新使用它

在我的程序的一部分中，有一个名为imageButton\u sound的按钮出现在xml文件活动\u考试\u类\u 1中。我想单击此按钮播放声音。第一次单击时，它会播放声音，但第二次它就不起作用了

我在AM_class_1.java文件中初始化这个xml文件

我的程序的顺序是-首先我将按下图像按钮\声音，然后按下同一文件的任何其他按钮，如图像按钮\ a、图像按钮\双图像按钮\ c……….等。 然后在满足某些条件后，程序将转到success\u exam.xml或fail\u exam.xml 这两个文件都包含一个按钮。按下按钮后，它将返回到“活动”\u“考试”\u“课程”\u 1，然后我将再次按ImageButton\u Sound，该过程将继续。 这是我的代码： 考试课程1.java：

slm；我认为你应该重新初始化计数器int Ks=0；在游戏的第一部分结束时。尝试按以下方式重新初始化：

 else{
     if((opt == R.id.imageButton_a && ks==1)||(opt == R.id.imageButton_b && ks==2)||
        (opt == R.id.imageButton_c && ks==3)||(opt == R.id.imageButton_d && ks==4)||
        (opt == R.id.imageButton_e && ks==5)||(opt == R.id.imageButton_f && ks==6)){
            Ks=0;
         setContentView(R.layout.success_exam1);
    joy_sound = MediaPlayer.create(this,R.raw.joy);
    joy_sound.start();



     }

     else{ Ks=0;
         setContentView(R.layout.fail_exam1);
            wrong_sound = MediaPlayer.create(this,R.raw.wrong);
            wrong_sound.start();


     }

我试过了，但没有成功。你能告诉我应该在哪一行重新初始化吗？试着在两行中重新初始化，就像上面一样。
