I can't clear the listview in my fragment before populating it again?

NOTE :
First of all before writing any thing. this is not a duplicate because if it is then why I will post this here. I didn't find any of the stackoverflow similar questions' answers helpful to me at all for 2 days straight.
THE PROBLEM :
I have an activity that takes two fields of data and then go to the next activity where it has a view pager and the activity opens 2 fragments the posts and the profile. the problem here is that when I go back to the first activity to input different data and go to the fragments the listview shows duplicate data.
I tried every possible solution but none works.
I tried to clear adapter.
I tried to pass empty adapter.
I tried more things in the life cycle of the fragment but nothing.
so please I need help. thanks in advance.

Your words in PostsFragment.java makes you element duplicate, In removeCommas() method first clears the words and then add the values to the words from data.

try this. searchResultses.clear(); at the start of addToClass()
static void addToClass() {
SearchResults s;
searchResultses.clear();
int offset = 0;
for (int j = 0; j < words.size(); j += 8) {
Log.d(TAG, String.valueOf(words.size()));
s = new SearchResults();
for (int i = 0; i < 8; i++) {
offset = 1;
s.add(words.get(i * offset));
}
offset += 1;
s.init();
searchResultses.add(s);
}
}

Android save info on return to activity

very new to android and wondering how I can make this sample code return to where it left off instead of having to reload the pictures on returning to the screen. Right now when I exit the screen and return I have to start all over. I have read and trying to understand the Android documents but having trouble making this work or where to begin... thanks everyone!

Write your activity so that it is aware of its current state.
In your onPause() method, save that state in any manner that you like. SharedPrefs, storage to a database, to a flat file, etc.
In your onResume() method, read that state and restore it.

Android getSharedPreferences onPause help store images

Trying to store images in this Flickr gallery so when user leaves the activity and returns the images don't need to be loaded again... I have been reading about getSharedPreferences used in the onPause method to keep the images from being destroyed... only problem is I can't find any examples dealing with images only text fields and such...thanks for any help

I think what you need is image caching. Storing SharedPreferences comes with memory limitations. If the number of images is large, you can try this library for image caching:
Hope this helps !

Android Flickr Json Caching Images

I am hoping someine can help me figure out how to cache the Flickr Json images to cache for faster loading and offline use...the code below is from a tutorial and i have all that figured out but am lost with trying to read/use the Android developer resources and other example on the web...be very grateful for a solution and help making this work...I am new to programming and appreciate the knowledge here :)

I suggest you have a look at Universal Image Loader on github.
Universal Image Loader allows you to easily integrate asynchronous image loading, caching and rendering of images on Android in list, gallery and grid format. If you want to implement your own solution, reading the source for this project is a great way to start. It was written by Sergey Tarasevich and is licensed under the BSD 3-clause.
