Hi to all,

I am new to android, I got problem with checkbox validation in android. When i click a button i should able to validate the checkbox, if it is checked i have to start new activity, if it is not checked i have to display error message as checkbox not checked.

Following is my code:

import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListe ner;

public class PreferenceMain extends Activity implements OnCheckedChangeListener {

CheckBox c1;
Context ctxt;
Button prefBtn;

public void onCreate(Bundle savedInstanceState) {

c1 = (CheckBox) findViewById(;
prefBtn = (Button) findViewById(;

prefBtn.setOnClickListener(new OnClickListener() {

public void onClick(View v) {
Log.d("Debug", "Button Clicked");


public void perform(){
if (c1.isChecked()){
Intent result = new Intent(getBaseContext(), Result.class);
//Should display alert to check the check box


Please help me, I am vexed with this issue almost for four days....

Thanks in advance
