如何使用json android发送单选按钮值并将案例选项切换到服务器?

标签: android json switch-statement radio-group

我正在尝试制作一个注册表单,其中所有值都保存在服务器上,但我不知道如何将单选按钮的值和切换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。请告诉我单选按钮和开关的正确方法吗?

您可以从OnCheckedChangedListener

获取已选中单选按钮的值
rgrp.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
    {
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // checkedId is the RadioButton selected
            RadioButton rb=(RadioButton)findViewById(checkedId);
            Toast.makeText(getApplicationContext(), rb.getText(), Toast.LENGTH_SHORT).show();
        }
    });

答案 1 :(得分:0)

尝试一下这个单选按钮它对我有用。

radio_button_value1 = ((RadioButton) findViewById(radioGroup1.getCheckedRadioButtonId())).getText().toString();

上面的代码是获取单选按钮的值。

替换您的此代码

// get selected radio button from radioGroup
        int selectedId = rgrp.getCheckedRadioButtonId();

使用此代码和测试

// get selected radio button from radioGroup
 int selectedId = rgrp.getCheckedRadioButtonId().getText().toString();

希望这个更新的代码可以帮助您。您只需要替换并检查

答案 2 :(得分:0)

添加全局String变量gender和boolean变量switchValue。

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

RadioGroupListener方法

 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();

}

获取开关状态

switchValue = swth.isChecked();

答案 3 :(得分:-1)

我自己的回答只需要在按钮内使用该代码:

 public void onClick(View v) {

            RadioGroup rgrp=(RadioGroup)findViewById(R.id.rg);

            RadioButton radioButton;

            int selectedId = rgrp.getCheckedRadioButtonId();

            // find the radiobutton by returned id
            radioButton = (RadioButton) findViewById(selectedId);

            Toast.makeText(RegistrationForm.this,
                    radioButton.getText(), Toast.LENGTH_SHORT).show();
