问题描述

我想使用JSON将值发送到服务器，当我选择复选框，我想送Y,,在我的JSON有效= Y为用户激活和关闭的状态是什么，我想是,,以下是$ C $Ç我的尝试，但它不工作，它总是显示激活= N

  proactives =（复选框）findViewById（R.id.edt_proactive）;
     如果（proactives.isChecked（）==真）
      {
          proactives.setTag（Y）;
      }
      如果（proactives.isChecked（）==假）
      {
          proactives.setTag（N）;
      }
 

解决方案

试试这个

  proactives.setOnCheckedChangeListener（新CompoundButton.OnCheckedChangeListener（）{
        @覆盖
        公共无效onCheckedChanged（CompoundButton compoundButton，布尔B）{
            如果（B）的
            {
                proactives.setTag（Y）;
            }
            如果（proactives.isChecked（）==假）
            {
                proactives.setTag（N）;
            }
        }
    }）;
 

或

  proactives.setOnCheckedChangeListener（新CompoundButton.OnCheckedChangeListener（）{
            @覆盖
            公共无效onCheckedChanged（CompoundButton compoundButton，布尔B）{
              proactives.setTag（BY：N）;
            }
        }）;
 

I am trying to send value to server using json,what I am trying is when I select checkbox I want to send "Y",,in my json active=Y is status of user activation and deactivation,,following is code what i tried,but its not working,it always shows active=N

 proactives=(CheckBox)findViewById(R.id.edt_proactive);
     if(proactives.isChecked()==true)
      {
          proactives.setTag("Y");
      }
      if(proactives.isChecked()==false)
      {
          proactives.setTag("N");
      }

解决方案

try this

proactives.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            if(b)
            {
                proactives.setTag("Y");
            }
            if(proactives.isChecked()==false)
            {
                proactives.setTag("N");
            }
        }
    });

OR

proactives.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
              proactives.setTag(b? "Y" : "N"); 
            }
        });
