推荐答案

您可以在适配器中实现自定义界面。当您从列表中检查项目时，您必须将结果传递给您的活动，稍后您可以对其进行总结。

You can implement a Custom interface in your Adapter. When you checked your item from list you have to pass the result to your Activity and later you can make sum of it.

interface CheckItemList{

        public void onCheckItem(int value){}

    }

在适配器类中创建接口和调用的引用onCheckItem（）

In your Adapter Class create a reference of Interface and call onCheckItem()

CheckItemList checkItemList = (CheckItemList) mContext;

satView.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

       @Override
       public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
              if(isChecked){
       checkItemList.onCheckItem(value);
         }
       }
   }
); 

在您的活动或某些单件类中实现CheckItemList接口。

Implement CheckItemList interface in your activity or some singleton class.

class MyActivity extends Activity implements CheckItemList.
  onCheckItem(int value){
  //Add your code to store checked value  
}

}
