Question

我试图计算选择了多少个复选框的计数，如果你取消选择一个，则假设将计数器更新为-1 ......所以，如果我选择4个复选框，它会显示“检查少“=计数4 ...然后我选择3，计数器= 3 ..这是我有的： // --- CheckBox 1 --- final CheckBox checkBox =（CheckBox）findViewById（R.id.checkBox1）;

   // ---CheckBox 2---
   final CheckBox checkBox2 = (CheckBox) findViewById(R.id.checkBox2);

   // ---CheckBox 3---

   final CheckBox checkBox3 = (CheckBox) findViewById(R.id.checkBox3);


   // ---CheckBox 4---

   final CheckBox checkBox4 = (CheckBox) findViewById(R.id.checkBox4);

   Button next = (Button) findViewById(R.id.button1);
   next.setOnClickListener(new View.OnClickListener() {
       public void onClick(View view) {
           if (checkBox.isChecked())
               count++;
           if (checkBox.isPressed())
               count--;
           if (checkBox2.isChecked())
               count++;
           if (checkBox2.isPressed())
               count--;
           if (checkBox3.isChecked())
               count++;
           if (checkBox3.isPressed())
               count--;
           if (checkBox4.isChecked())
               count++;
           if (checkBox4.isPressed())
               count--;
           if (count == pubsSelected){
           Intent myIntent = new Intent(view.getContext(), Screen2.class);
           startActivityForResult(myIntent, 0);
       }
           else if (count < pubsSelected)
               DisplayToast("Pick more pubs/holes");
           else if (count > pubsSelected)
               DisplayToast("Pick less pubs/holes");
       }

   });

}

我认为你应该这样做：

if (checkBox.isChecked())
{
    count++;
}else
{
    count--;
}

 if (checkBox2.isChecked())
{
    count++;
}else
{
    count--;
}
