Endless RecyclerView with ProgressBar in Search activity

I am new at android. I have a search activity which searches for a query using async task, i want to implement endless/infinite scrolling when user reaches bottom. I want to add a parameter startrow to async task which will then be passed on to the server telling which row to begin.
// CONNECTION_TIMEOUT and READ_TIMEOUT are in milliseconds
public static final int CONNECTION_TIMEOUT = 10000;
public static final int READ_TIMEOUT = 15000;
private RecyclerView mRVFish;
private AdapterFish mAdapter;
private LinearLayoutManager mLayoutManager;
private String searchQuery;
SearchView searchView = null;
private String query;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// adds item to action bar
getMenuInflater().inflate(R.menu.search_main, menu);
// Get Search item from action bar and Get Search service
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchManager searchManager = (SearchManager) MainActivity.this.getSystemService(Context.SEARCH_SERVICE);
if (searchItem != null) {
searchView = (SearchView) searchItem.getActionView();
}
if (searchView != null) {
searchView.setSearchableInfo(searchManager.getSearchableInfo(MainActivity.this.getComponentName()));
searchView.setIconified(false);
}
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}
Every time when you press search button on keypad an Activity is recreated which in turn calls this function
#Override

// Get search query and create object of class AsyncFetch
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {

}
}
Here is my initial Fragment Code
public class WhatsHotFragment extends Fragment {
public WhatsHotFragment(){}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_whats_hot, container, false);
return rootView;
}
}

what i want to ask is that how can i implement initViews() function in Activity to Fragment
So
Buttom button
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_whats_hot, container, false);
return rootView;
}
Override onActivityCreated
Then
button = (Button)getView()findViewById(R.id.buttonSubmit);
// similarly for other views
There is no harm in initializing view in onActivitedCreated.
You can also initialize your view's in onCreateView
Buttom button
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_whats_hot, container, false);
button = button = (Button)getView()findViewById(R.id.buttonSubmit);
// similarly for other views
return rootView;
}
For more info
http://developer.android.com/guide/components/fragments.html

Fragment lifecycle is a bit different than Activity lifecycle.
Although a fragment has the onCreate(), onStart(), onResume() etc. methods which are called along with the same method of the activity, we set up a fragment differently.
A fragment inflates its user interface in its onCreateView() method, which returns a View.
After that, we do further setup in onViewCreated(). (E.g. set up onClickListeners, etc.).
Of course you can find this all here: http://developer.android.com/guide/components/fragments.html
Edit:
Although it's possible to setup subviews in onActivityCreated(), it's better to do the setup in onViewCreated(), because onViewCreated() was intended to do this, so it conforms better to the docs.

Fragment Tabs not Appearing

In my program i am showing multilevel Listview, but whenever i am calling another Activity then Fragment Tabs are not appearing.

This is the normal behavior because you are moving from the Fragment Activity to a normal Activity. But only your first activity has the tabs.
The correct way of doing this is to remove the intents and the new activities. Instead it should be replaced with fragments itself.
For example, in the list item click, stop calling the Intent to the new fragment activity, and replace it calling a fragment itself.
There will be only one Activity and that will be the one which is holding the tabs and all others should be fragments. You just need to replace the fragments from within the same activity.

Android Animation Sequence Loads Slowly - Appears To Hang [duplicate]

I have an android Animation which loads a series of sequential dots (publishProgress) however there is a 10+ second delay before they start because I have them as a part of my AsyncTask which loads once the data is processing (technically - the two should be related - but it visually causes there to be a delay) how can I call this animation when the class first starts instead? I need to remove this visual animation delay.

You can use onPreExecute() and onPostExecute() methods from the AsyncTask to set the loading before/ remove it after the work is done.
try:
protected void onPreExecute() {
setProgressImgView(R.drawable.loading_full,
R.drawable.loading_empty, R.drawable.loading_empty,
R.drawable.loading_empty, R.drawable.loading_empty);
}
protected void onPostExecute(InputStream stream) {
setProgressImgView(R.drawable.loading_full,
R.drawable.loading_full, R.drawable.loading_full,
R.drawable.loading_full, R.drawable.loading_full);
// This method is called to parse the response and save the
// ArrayLists
success();
}
