我如何使用json android发送单选按钮值和切换大小写选项到服务器? [英] how can i send radio button value and switch case option to server using json android?

问题描述

我正在尝试制作一个注册表，其中所有值都保存在服务器上，但是我不知道如何将单选按钮的值发送和将选项按钮的值发送到服务器. 我尝试为单选按钮实现此功能，但是当此活动打开时，它仅显示单选按钮值一次.请告诉我针对单选按钮和开关执行此操作的正确方法吗?

I'm trying to make a registration form where all values are saving on the server, but i dont know how to send the radio buttons' value and switch option buttons' value to server. I tried implementing this for the Radio buttons, but when this activity opens, it only shows radio button value that too only once. Kindly tell me the correct way of doing this for both radio button and switch?

推荐答案

添加全局String变量性别和布尔变量switchValue.

Add a global String variable gender and boolean variable switchValue.

String gender="Male" ;
boolean switchValue = false ;

内部RadioGroupListener方法

Inside RadioGroupListener Method

 public void addListenerOnButton() {
    RadioGroup rgrp=(RadioGroup)findViewById(R.id.rg);
    rgrp.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup radioGroup, int i) {
            if(i==R.id.rgm){
              gender="Male" ; 
             }else{
              gender="Female";
         }
    }
    });
    Toast.makeText(RegistrationForm.this,
            radioButton.getText(), Toast.LENGTH_SHORT).show();

}

用于获取开关状态

switchValue = swth.isChecked();
