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?

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();
}
});
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
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();
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();
