Hi,

I am beginner in android development. To understand radioButton click event I have written below code to capture clickevent of radio button.Code is as below. Code is working only for first radio button press. Please suggest

package com.example.radiobuttonpress;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.RadioGroup.OnCheckedChangeListener;
import android.widget.RelativeLayout;
import android.util.Log;

public class MainActivity extends ActionBarActivity {

private static final String logTag = "MainActivity";
RadioGroup checkGroup;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Log.i(logTag,"Calling checkButtonPressed");
    checkButtonPressed();

public void checkButtonPressed(){
    RelativeLayout layout = (RelativeLayout)findViewById(R.id.main_container);
    Log.i(logTag,"Calling getCheckedRadioButtonId");
    final RadioButton rd = (RadioButton)findViewById(checkGroup.getCheckedRadioButtonId());
    rd.setOnClickListener(new OnClickListener(){
            public void onClick(View v){
                Log.i(logTag,"Check switch value");

                switch(rd.getId()){
                case R.id.radio0:
                    Log.i(logTag,"Button 0 Pressed");
                  rd.setText("First Button is Pressed");
                  break;
                case R.id.radio1:
                    Log.i(logTag,"Button 1 Pressed");
                  rd.setText("Second Button is Pressed");

                  break;
                case R.id.radio2:
                    Log.i(logTag,"Button 2 Pressed");
                  rd.setText("Third Button is Pressed");
                  break;
                }
            }
    });

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

}
