import android.app.Activity;   
import android.os.Bundle;   
import android.widget.Button;   
import android.view.VIEw;   
import android.app.AlertDialog;   
import android.content.DialogInterface;   
public class AlertDialogBuilderSample extends Activity {   
@Override   
public void onCreate(Bundle icicle) {   
super.onCreate(icicle);   
setContentVIEw(R.layout.main);   
final Button btnQuit = (Button) findVIEwById(R.id.btnQuit);   
btnQuit.setOnClickListener(new Button.OnClickListener() {   
public void onClick(VIEw v) {   
new AlertDialog.Builder(AlertDialogBuilderSample.this)   
.setTitle(“Question”)   
.setMessage(“Are you sure that you want to quit?”)   
.setIcon(R.drawable.question)   
.setPositiveButton(“Yes”, new DialogInterface.OnClickListener() {   
public void onClick(DialogInterface dialog, int whichButton) {   
setResult(RESULT_OK);   
finish();   
}   
})   
.setNegativeButton(“No”, new DialogInterface.OnClickListener() 
{   
public void onClick(DialogInterface dialog, int whichButton) 
{   
}   
})   
.show();   
}   
});   
final Button btnTravels = (Button) findVIEwById(R.id.btnTravels);   
btnTravels.setOnClickListener(new Button.OnClickListener() 
{   
public void onClick(VIEw v) {   
new AlertDialog.Builder(AlertDialogBuilderSample.this)   
.setTitle(“I want to go to”)   
.setItems(R.array.items_indide_dialog,   
new DialogInterface.OnClickListener() {   
public void onClick(DialogInterface dialog, int whichcountry) 
{   
String[] travelcountrIEs =   
getResources().getStringArray(R.array.items_indide_dialog);   
new AlertDialog.Builder(AlertDialogBuilderSample.this)   
.setMessage(“I’m going to “ + travelcountrIEs[whichcountry])   
.setNeutralButton(“Cancel”,   
new DialogInterface.OnClickListener() {   
public void onClick(DialogInterface dialog, int whichButton)

}   
})
