how can i send radio button value and switch case option to server using json android?

问题

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?

回答1:

you can get the value of checked radio button from OnCheckedChangedListener

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();
        }
    });

回答2:

try this out incase of radio button it works for me.

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

above code is to get value of the radio button.

replace your this code

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

with this code and test

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

hope this updated code helps you.you just have to replace and check

回答3:

Add a global String variable gender and boolean variable switchValue.

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

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();

}

For Getting the switch state

switchValue = swth.isChecked();

回答4:

i gt my answer by myself just need to use that code inside button:

 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();
