[android-developers] Quiz Application

Hi,

I am a beginner and I am stuck whilst developing a simple quiz
application in android. The code is below. onClick next button is not
displaying the next random question. Any help?

package com.quiz;

import java.util.Random;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;

public class Quiz2Activity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
Random r = new Random();
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final String[] Countries =
{"India","U.S","Singapore","Malaysia","Sri
Lanka","Thailand","Indonesia","China","Japan","Korea","Vietnam"};
final String[] Capitals = {"Delhi","Washington D.C","Singapore
City","Kaula lampur", "Colombo",
"Bangkok","Jakarta","Beiing","Tokyo","Seoul","Ho Chi Min City"};
String question;
RadioGroup rg1 = (RadioGroup)findViewById(R.id.rg1);
Button but1 = (Button) findViewById(R.id.but1);
for(int i=0;i<4;i++){
int num = r.nextInt(10);
question = "Whats the capital of the country " +
Countries[num];
TextView Question = (TextView) findViewById(R.id.ques);
Question.setText(question);
RadioButton ans1 = (RadioButton) findViewById(R.id.ans1);
RadioButton ans2 = (RadioButton) findViewById(R.id.ans2);
RadioButton ans3 = (RadioButton) findViewById(R.id.ans3);
RadioButton ans4 = (RadioButton) findViewById(R.id.ans4);
ans1.setText(Capitals[num+1]);
ans2.setText(Capitals[num]);
ans3.setText(Capitals[num+2]);
ans4.setText(Capitals[num-2]);

}
but1.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
finish();
Bundle tempbundle = new Bundle();
onCreate(tempbundle);
}
});
}
}

I suspect but1.setOnClickListener method.

Regards,
Subbu
