So here is the code. Its pretty self explanatory. The only problem I am having is retaining the value for int level. Its lost every time. I need the value to be retained and it will work. This is a snapshot. It should be extensible to as many levels deep and as many items per level.
XML code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context=".MainActivity" >
<ListView
android:id="#+id/listView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
</ListView>
</RelativeLayout>
Java code:
package com.example.kjkjsdkjdsjkdfs;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class MainActivity extends ListActivity {
String categoryselected = "main";
public int level = 0;
#SuppressWarnings("null")
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] array;
Intent received = getIntent();
// Setup as main ListView
if (received == null || !received.hasExtra("array")) {

}
// Setup as sub ListView
else {
array = received.getStringArrayExtra("array");
}
if(received != null || !received.hasExtra("level")) {
level = received.getIntExtra("level", 0);
}
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, array));
}
#Override

Update your code like this :
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class ListItems extends ListActivity {
String categoryselected = "main";
public int level = 0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] array;
Intent received = getIntent();
// Setup as main ListView
if (received == null || !received.hasExtra("array")) {
array = new String[] { "1", "2", "3" };
}
// Setup as sub ListView
else {
array = received.getStringArrayExtra("array");
}
if(received != null || !received.hasExtra("level")) {
level = received.getIntExtra("level", 0);
}
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, array));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
level = level + 1;
Intent starting = new Intent(ListItems.this, ListItems.class);
switch (level) {
case 1:
switch (position) {
case 0:
starting.putExtra("array", new String[] { "1a", "1b", "1c" });
starting.putExtra("level", level);
break;
case 1:
starting.putExtra("array", new String[] { "2a", "2b", "2c" });
starting.putExtra("level", level);
break;
case 2:
starting.putExtra("array", new String[] { "3a", "3b", "3c" });
starting.putExtra("level", level);
break;
}
break;
case 2:
switch (position) {
case 0:
starting.putExtra("array", new String[] { "1aa", "1ab" });
starting.putExtra("level", level);
break;
}
break;
case 3:

I'm currently developing an android application where I'm using a navigation drawer as well as the swipe gesture using viewPager to traverse through fragments.
Basically, I want the user to be able to select pages (fragments) using the navigation drawer and be able to swipe to the next page (fragment).
My problem right now is that they overlap. The swipe gesture works as expected but when I select another page on the nav drawer they underlying page doesn't disappear. I need someway to "refresh" each fragment.
Here is my code in the MainActivity.java page
package com.example.home.cloud;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;

The trouble is that you're displaying your fragments in two different ways. Your displayView() method is creating new fragments and displaying them, rather than showing the ones which are already loaded in the ViewPager. To fix this, you need displayView() to instead set your ViewPager position.
private void displayView(int position) {
mPager.setCurrentItem(position);
getSupportActionBar().setTitle(mPagerAdapter.getPageTitle(position));
}
I am working on this application that has a viewPager and a few swipeable fragments in its MainActivity. Today I implemented navigation drawer but I do not know how to control which fragment is shown from drawer`s DrawerItemClickListener class. Is there a solution or I was just moving in a wrong direction and have to change the way navigation drawer is implemented?
Tutorial suggests to use the getFragmentManager method which does not work for me.
Thanks.
Here is DrawerItemClickListener class:

import android.util.Log;
import android.view.View;

import android.widget.AdapterView;
public class DrawerItemClickListener implements ListView.OnItemClickListener
{
public int FragmentNumber;
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long
id) {
selectItem(position);
}
private void selectItem(int position) {
Fragment fragment = null;
switch (position) {
case 0:
fragment = new StartFragment();
FragmentNumber=0;
break;
case 1:
fragment = new MesFragment();
FragmentNumber=1;
break;
case 2:
fragment = new NaujienosFragment();
FragmentNumber=2;
break;
case 3:
fragment = new InstruktoriaiFragment();
FragmentNumber=3;
break;
case 4:
fragment = new MetodikaFragment();
FragmentNumber=4;
break;
case 5:
fragment = new GalerijaFragment();
FragmentNumber=5;
break;
case 6:
fragment = new InstruktoriaiFragment();
FragmentNumber=6;
break;
case 7:
fragment = new AtsiliepimaiFragment();
FragmentNumber=7;
break;
case 8:
fragment = new DrufunparkFragment();
FragmentNumber=8;
break;
case 9:
FragmentNumber=9;
fragment = new KontaktaiFragment();
break;
default:
break;
}
if (fragment != null) {
//tutorial suggests this code:
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);

I figured out my mistake, it all has to be inside MainActivity.java, DrawerItemClickListener is an inner class.
Still have not found a way to navigate between swipeable fragments from the navDrawer, probably it is impossible.
I am trying to make a alphabet exam. I have a ImageView11 which shows the a random alphabet which you have to guess. And the imageView_alphabet_image_1 and imageView_alphabet_image_2 will show two options which I have to guess and I will drag the ImageView11 image on correct ImageView which is showing down. But I'm able to do it for only first time when i click on refresh it always showing incorrect toast

I checked you code the problem is in your onDrag method.
case DragEvent.ACTION_DROP event did not call because of you did not return flag case DragEvent.ACTION_DRAG_STARTED: event. You have to pass true flag like below code
case DragEvent.ACTION_DRAG_STARTED:
return true;
I have an application with a list view and a custom adapter where I add custom objects to the list view. I know how to delete objects through long-pressing one of the list items in the list, but I have a trash can action bar button and I want it so that when you click on that button, it brings up the same CAB as if you were long-pressing a list item, and I want the user to be able to select multiple list items, and then click a delete button on the CAB.

Basically, with this code, if I click on the trash-can action bar button, the CAB shows up, but I can't select any items on the list and proceed to delete them. Any help is greatly appreciated.
This is a tricky one. I used CheckedTextView's for multiple selections inside the list however when the list scrolls the adapter re-uses the old views and sometimes checks the wrong items. To overcome that I used an array of all the currently checked items, so the adapter can know which items should be checked.
Before going back to the original list you need to call notifyDataSetChanged(), which notifies to redrawn the visible views therefore uncheck/delete the selections (depends on what action you chose back at the CAB).
