How to replace the baseadapter value and how to stop the pagination loading in android filter screen?

I have worked with the concept of filter that have to filter the job from job list based on skills and some list or there.
https://postimg.org/image/g3p1z6lbd/ - DashBoard Fragment.
About DashBoardFragment:
Contains job list view.
Dash Filter Button. - which redirect to the Filter screen.
public class DashBoardRefactor extends Fragment {

Log.e("get pos", "get pooooossss---->" + dashRowList.get(position));
final DashListModel dashModel = dashRowList.get(position);
dashHolder = new ViewHolder(convertView);
//Assign the value into screen
dashHolder.dash_company_name.setText(dashModel.getDashCompanyName());
}
the above code for displaying dashboard fragment list.
https://postimg.org/image/nqvp1dud9/ - This link is FilterScreen
By using this image if i filter the job based on the designed UI detail. That should replace into the DashboadFragment list The result should display into the DashBoard Fragment. How can I add pagination on Filter screen the same which have in DashBoardFragment.

Put this code here

}
}else{

FacultyList.setVisibiltity(View.GONE) ;
}
progressDialog.dismiss();
}

you can try this:
this is the adapter class code.
public class CustomTaskHistory extends ArrayAdapter<String> {
private Activity context;
ArrayList<String> listTasks = new ArrayList<String>();
String fetchRefID;
StringBuilder responseOutput;
ProgressDialog progress;
String resultOutput;
public String getFetchRefID() {
return fetchRefID;
}
public void setFetchRefID(String fetchRefID) {
this.fetchRefID = fetchRefID;
}
public CustomTaskHistory(Activity context, ArrayList<String> listTasks) {
super(context, R.layout.content_main, listTasks);
this.context = context;
this.listTasks = listTasks;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.list_task_history, null, true);
TextView textViewName = (TextView) listViewItem.findViewById(R.id.textViewName);
LinearLayout linearLayout = (LinearLayout) listViewItem.findViewById(R.id.firstLayout);
//System.out.println("client_id" + _clientID);
//TextView textViewDesc = (TextView) listViewItem.findViewById(R.id.textViewDesc);
//ImageView image = (ImageView) listViewItem.findViewById(R.id.imageView);
if (position % 2 != 0) {
linearLayout.setBackgroundResource(R.color.sky_blue);
} else {
linearLayout.setBackgroundResource(R.color.white);
}
textViewName.setText(listTasks.get(position));
return listViewItem;
}
}
and now in the parent class you must have already added a list view in your xml file so now display code for it is below:
CustomTaskHistory customList = new CustomTaskHistory(TaskHistory.this, task_history_name);
listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(customList);
you can also perform any action on clicking cells of listview.If needed code for it is below add just below the above code:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent nextScreen2 = new Intent(getApplicationContext(), SubscribeProgrammes.class);
nextScreen2.putExtra("CLIENT_ID", _clientID);
nextScreen2.putExtra("REFERENCE_ID", reference_IDs.get(i));
startActivity(nextScreen2);
Toast.makeText(getApplicationContext(), "You Clicked " + task_list.get(i), Toast.LENGTH_SHORT).show();
}
});

getView in base adapter is not working

I'm trying to create base adapter for Favorites.class so I can display items in it.
The getView method is not being called and the Activity won't show any view.
BaseAdapter:
public class fYtAdapter extends BaseAdapter {
private List<SearchResult> mfVideoList = null;
private LayoutInflater mfLayoutInflater = null;
private Favorites fActivity = null;
public fYtAdapter(Favorites iActivity){
fActivity = iActivity;
mfLayoutInflater = LayoutInflater.from(fActivity);
}
public void setmVideoList(List<SearchResult> mVideoList){
this.mfVideoList = mVideoList;
}
#Override
public int getCount() {
return (mfVideoList == null)? (0):(mfVideoList.size());
}
#Override
public Object getItem(int position) {
return (mfVideoList != null && mfVideoList.size()>position)? (mfVideoList.get(position)):(null);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder mHolder;
if(convertView != null){
mHolder = (ViewHolder)convertView.getTag();
}else{
mHolder = new ViewHolder();
convertView = mfLayoutInflater.inflate(R.layout.view_video_item,null);
mHolder.mVideoThumbnail = (ImageView)convertView.findViewById(R.id.video_thumbnail);
mHolder.mVideoTitle = (TextView)convertView.findViewById(R.id.video_title);
convertView.setTag(mHolder);
}
//Setting the data
final SearchResult result = mfVideoList.get(position);
mHolder.mVideoTitle.setText(result.getSnippet().getTitle());
//Loading the image
Picasso.with(fActivity).load(result.getSnippet().getThumbnails().getMedium().getUrl()).into(mHolder.mVideoThumbnail);
return convertView;
}
private class ViewHolder{
private TextView mVideoTitle = null;
private ImageView mVideoThumbnail = null;
}
}
Favorites.class
public class Favorites extends ActionBarActivity
implements View.OnClickListener, AdapterView.OnItemClickListener, ServerResponseListener{
private LayoutInflater mLayoutInflater = null;
private ProgressDialog mLoadingDialog = null;
private fYtAdapter mYtadapter = null;
String vidID = null, vidTitle = null, vidThumbnail = null;
ListView mFavLsv;
Bundle extras;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.favorites_layout);
getSupportActionBar().setTitle("Favorites");
initializeViews();
extras = getIntent().getExtras();
this.vidID = extras.getString("id");
this.vidTitle = extras.getString("title");
this.vidThumbnail = extras.getString("thumbnail");
}
public void initializeViews(){
mLayoutInflater = LayoutInflater.from(this);
mFavLsv = (ListView)findViewById(R.id.yt_fav_lst);
}
#Override

return super.onCreateOptionsMenu(menu);
}
//Not needed in this Activity
#Override
public void onClick(View v) {
}
//To start video
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent videoIntent = YouTubeStandalonePlayer.createVideoIntent(this, AppConstants.KEY, vidID);
startActivity(videoIntent);
}
#Override
public void prepareRequest(Object... objects) {
//Parse the response based on type of request
Integer reqCode = (Integer) objects[0];
if(reqCode == null || reqCode == 0)
throw new NullPointerException("Request Code's value is Invalid.");
String dialogMsg = null;
switch(reqCode){
case SEARCH_VIDEO:
dialogMsg = SEARCH_VIDEO_MSG;
break;
}
if(mLoadingDialog != null && !mLoadingDialog.isShowing())
mLoadingDialog = ProgressDialog.show(this, DIALOG_TITLE, dialogMsg, true, true);
}
#Override
public void goBackground(Object... objects) {
}
#Override
public void completedRequest(Object... objects) {
//Dismiss the dialog
if(mLoadingDialog != null && mLoadingDialog.isShowing())
mLoadingDialog.dismiss();
//Parse the response based on type of request
Integer reqCode = (Integer) objects[0];
if(reqCode == null || reqCode == 0)
throw new NullPointerException("Request Code's value is Invalid.");
switch (reqCode){
case SEARCH_VIDEO:
if(mYtadapter == null){
mYtadapter = new fYtAdapter(this);
mYtadapter.setmVideoList((List<SearchResult>)objects[1]);
mFavLsv.setAdapter(mYtadapter);
}else{
mYtadapter.setmVideoList((List<SearchResult>) objects[1]);
mYtadapter.notifyDataSetChanged();
}
break;
}
}
}
I got another base adapter for another Activity and it is working fine.
I can't figure out why this is not working in here.
I need to display the view (with thumbnail(vidThumbnail) and title(vidTitle) in Favorites.class
*It seems that it won't got into "completedRequest" at all.

I faced this same issue. And I got the solution from here.. Link
Solution:
The only reasons getView() is not called are:
1) getCount() returns 0
2) You forget to call setListAdapter on the ListView.
3) If the ListView's visibility (or its container's visibility) is GONE.

Initialize your adapter and then set it to your ListView inside your initializeViews() method using mFavLsv.setAdapter(youradapter);

you have to add one more line -
mFavLsv.setAdapter(mYtadapter );
You missed set adapter in listview.

Highlighting row in listview that uses arrayadapter

I have created a custom lisview with images and text by using an array adapter. I would like to highlight one of the row manually, but I cannot seem to do this. I have tried using setItemChecked and setSelection(1);. I have made sure to disable touch events by calling listView.setEnabled(false);, as I read that manual selection might not work if touch events are enabled. Any insight into this matter would be greatly appreciated. I have included my source code below.

return rowView;
}
}

put setonclick listener in rootview object which are inflate by you in getview method this will solve your issue and on click event you can change the background of rootview and many more you can do with it.
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(rowResourceId, parent, false);
ImageView imageView = (ImageView) rowView.findViewById(R.id.imageView);
TextView textView = (TextView) rowView.findViewById(R.id.textView);
int id = Integer.parseInt(Ids[position]);
String imageFile = Model.GetbyId(id).IconFile;
textView.setText(Model.GetbyId(id).Name);
if (position == selectedItem)
{
rootView /*or you can use any viewgroup*/
.setBackgroundResource(R.drawable.background_dark_blue);
}
else
{
rootView
.setBackgroundResource(R.drawable.border02);
}
return rowView;
}
private int selectedItem;
public void setSelectedItem(int position) {
selectedItem = position;
}
i know this is not good solutionbut might this help you out you can use setSelectedItem method to highlight row
and please use static placeholder class for efficiency and use position field in static placeholder class to get position of selected row

You can do something like this, protected void onListItemClick(ListView l, View v, int position, long id) {YourObject o = l.getItemAtPosition(position);}. After that you have to set what ever you need to display in your pop-up screen via this obtained object.
