pantalla - ¿Cómo puedo enviar el valor del botón de opción y cambiar la opción de la caja al servidor usando json android?

modo accesibilidad android

Question

Intento crear un formulario de registro donde todos los valores se guarden en el servidor, pero no sé cómo enviar el valor de los botones de radio y cambiar el valor de los botones de opción al servidor. Intenté implementar esto para los botones de Radio, pero cuando esta actividad se abre, solo muestra el valor del botón de opción una sola vez. Amablemente dime la forma correcta de hacer esto para el botón de radio y el interruptor?

Answer 1

Agregue una variable global de género String y una variable booleana switchValue.

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

Dentro del método RadioGroupListener

 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();

}

Para obtener el estado del interruptor

switchValue = swth.isChecked();

Answer 2

Prueba esto en caso de que el botón de radio funcione para mí.

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

el código anterior es para obtener el valor del botón de radio.

reemplace su código

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

con este código y prueba

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

Espero que este código actualizado te ayude. Solo tienes que reemplazar y verificar

Answer 3

Solo tengo que responder por mi cuenta, necesito usar ese código dentro del botón:

 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();

Answer 4

puede obtener el valor del botón de OnCheckedChangedListener en 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();
        }
    });
