我要讓變量a +1如果checkbox1和器isChecked當我改變我的檢查例如checkbox2我想使a -1和b +1 我該怎麼做？

Answer 1

checkBox2.setOnCheckedChangeListener(new OnCheckedChangeListener() { 

       @Override 
       public void onCheckedChanged(CompoundButton buttonView, 
         boolean isChecked) { 
        a = -1; 
        b = 1; 
       } 
      }); 

Answer 2

checkBox1.setOnCheckedChangeListener(new OnCheckedChangeListener() { 

       @Override 
       public void onCheckedChanged(CompoundButton buttonView, 
         boolean isChecked) { 
        a++; 
        b =0; 
        c=0; 
       } 
      }); 
checkBox2.setOnCheckedChangeListener(new OnCheckedChangeListener() { 

       @Override 
       public void onCheckedChanged(CompoundButton buttonView, 
         boolean isChecked) { 
        b++; 
        a =0; 
        c=0; 
       } 
      }); 
checkBox1.setOnCheckedChangeListener(new OnCheckedChangeListener() { 

       @Override 
       public void onCheckedChanged(CompoundButton buttonView, 
        boolean isChecked) { 
       c++;
