[android-beginners] ListView onListItemClick
Hi,
I am creating an application which parses an XML from the web and
displays the items of a tag in another ListView. Basically i
want to know an effecient way of using ListView all throughout the
application.
Ex:
Part
1
Part 2Part 3
My Bookshelf -Click->Opens another ListView >Book 1---
> Click--> ListView->First Page
Options
Book 2
Help
Exit
I am able to go from part 1 to part 2. but not from part 2 to part3. I
might be doing some mistake in part 1 to part 2 itself.
Please advise. I am very confused and stuck.
My code:

package com.vijay.simple;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class Simple extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b1 = (Button) findViewById(R.id.button_id1);
b1.setOnClickListener(buttonListener1);
Button b2 = (Button) findViewById(R.id.button_id2);
b2.setOnClickListener(buttonListener2);
}
private OnClickListener buttonListener1 = new OnClickListener(){
public void onClick(View v1){
