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 {

this.c = c;
this.dashListView = dashListView;
this.dashRowList = dashRowList;
}
#Override
public int getCount() {
return this.dashRowList.size();
}
#Override
public Object getItem(int position) {
return dashRowList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder dashHolder;
if (inflater == null)
inflater = (LayoutInflater) c
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.dashboard_jobdetails_list, null);
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.

Replacing Fragment in ViewPager shows blank screen?

I'm having a lot of trouble getting Fragments to work with Tabs/Swiping. I have one activity and two Fragments, one which has a ListView. What I want is when I swipe from fragment 1 to the fragment with the ListView, to refresh the ListView or if possible recreate the second fragment....
What I am trying right now is to use FragmentTransaction.replace() like this:
public void onTabSelected(Tab arg0, android.app.FragmentTransaction arg1) {
// TODO Auto-generated method stub
Fragment frag = new FragmentTwo();
FragmentTransaction trans = getSupportFragmentManager().beginTransaction();
if (arg0.getPosition() == 1) {
trans.replace(R.id.pager, frag);
trans.addToBackStack(null);
trans.commit();
}
}
So I thought that when I swipe to tab 2, which is the one with the ListView, it would replace it with a new one, which it creates. What is actually happening is that when I swipe to tab 2, it recreates the fragment with the ListView (I know because I have a dialog in the onCreateView which shows to the screen) but then the fragment/tab is blank/black. What am I doing wrong? Where does this fragment which is created go?
I don't know if the code of the fragments is relevant but please let me know if I should post it and I can do that. This is my PagerAdapter class.
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
return new FragmentOne();
case 1:
return new FragmentTwo();
case 2:
return new FragmentThree();
}
return null;
}
#Override
public int getCount() {
// get item count - equal to number of tabs
return 3;
}
}
Thanks for any help! I'm really pulling my hair out over this one :(
Edit:
When you swipe from tab 1 to tab 2, tab 2 shows my dialog and then loads the tab, but if I go back to tab 1 its all black...and if I then go to tab 2 again, it creates again and shows my dialog and then goes black as well...
Edit: (adding listview fragment code)

Try to extend FragmentStatePagerAdapter instead of FragmentPagerAdapter.
Here's my code for fragments and it works fine for me:
//Adapter
public class AllPagesAdapter extends FragmentStatePagerAdapter {
public AllPagesAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
return new Android();
case 1:
return new CoreJava();
case 2:
return new J2EE();
case 3:
return new Database();
case 4:
return new WebServices();
}
return null;
}
#Override
public int getCount() {
return 5;
}
}
//For example, this is one fragment:
public class Database extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View databaseview = inflater.inflate(R.layout.database, container, false);
return databaseview;
}
}
//My MainActivity
public class AllActivities extends FragmentActivity implements ActionBar.TabListener {
public ViewPager viewPager;
private AllPagesAdapter mAdapter;
private ActionBar actionBar;
private String [] tabs = {"Android","CoreJava","J2EE","Database","Web Services"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Initializing all stuff
viewPager = (ViewPager)findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new AllPagesAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(true);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
//Add the tabs here
for(String tab_name:tabs){
actionBar.addTab(actionBar.newTab().setText(tab_name).setTabListener(this));
}
viewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener(){
#Override
public void onPageSelected(int position){
//on Page change, that particular page should be selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0,float arg1,int arg2){
}
#Override
public void onPageScrollStateChanged(int position){
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction fragmentTransaction) {
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction fragmentTransaction) {
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction fragmentTransaction) {
viewPager.setCurrentItem(tab.getPosition());
}
}
Let me know if you also want the implementation of the listview in any one fragment.
Hope this helps..:)

My children fragments are in a ViewPager. I just replace the ViewPage adapter by FragmentStatePagerAdapter instead of FragmentPagerAdapter
Child Fragment
....
mViewPager.setAdapter(new SearchOriginTabsPagerAdapter(getFragmentManager()));
Adapter...
public class SearchOriginTabsPagerAdapter extends FragmentStatePagerAdapter {
public SearchOriginTabsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
return new NearbyFragment();
case 1:
return new RecentOriginFragment();
}
return null;
}
#Override
public int getCount() {
// get item count - equal to number of tabs
return 2;
}
}

Alright.. Here's the thing..
I didn't really use your code but used similar concept. Its gonna be a complete solution.

viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(true);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
//Add the tabs here
for(String tab_name:tabs){
actionBar.addTab(actionBar.newTab().setText(tab_name).setTabListener(this));
}
viewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener(){

If anyone using viewpager2 then use the below constructor.
FragmentStateAdapter(fragmentManager, lifecycle)

How to perform search in the expandable listview which is in the fragment?

Here is the thing..
I have one activity in which i have implmented the ActionBarSherlock,View Pager with Tab Navigation.
In Action Bar i have placed the search view.Now i am adding the list of fragments from the activity using viewPagerAdapter.
Now, In fragments i have placed the expandable listview and i am display the products with its section name in the expandable listview.
What i want to do ::
I want to perform the search of products from the expandable listview.

I have placed the searchview in the Activity from which i am calling the different fragments.So how to perform the search ???

I am actually getting the action bar in wrong way.
TO use the action bar in each fragment ::
i have placed the setHasOptionsMenu(true); in my onCreate() of fragment
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
After that i am able to use the onCreateOptionMenu() in which i placed the searchview and now i am able to search the date from the expandable listview,getting text from searchview.
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.menu, menu);
final MenuItem searchItem = menu.findItem(R.id.menu_item_search);
final SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setQueryHint("Search Here");
}
And now m done,Problem resolved.... ;)

How to apply filter to customlistview

I am using Custom adapter for my listview and I want to apply filter for searching perticular item from the list how to do that? I Know that how to do that for adapter extending ArrayAdapter but in my case it is simplesectionadapter.I have one editText above the listview from the text entered in the edittext I want to serch the Item.
Collections.sort(contents, new Comparator<CategoryPojo>() {
#Override
public int compare(CategoryPojo s1, CategoryPojo s2) {

}
};

You can use addTextChangedListener & in onTextChanged method get your search string & match this string with your listItems & prepare new list of searched items.Then reinitialize your adapter & set it to ListView.

hide section labels in listview

I use component android-section-list (http://code.google.com/p/android-section-list/) to create sections in my listView. How can I hide sections after push some button?
I try to do like
public void onClick(View v) {
switch(v.getId()) {

View convertView = inflater.inflate(R.layout.market_list_separator, null, false);

separatorLayout.setVisibility(View.GONE);
sectionAdapter.notifyDataSetChanged();
setButtonState(sortByTitle);
adapter.sort((Comparator<SectionListItem>) sortByTitle());
break;

Where can I put check for visibility in this Adapter?

This works but will be overwritten by the getView() method in the adapter . You must handle this in the adapter bcoz each time view becomes visible on the screen the View is updated so becomes visible in your case.
For the Data you are storing add a Visibility field ( by default keep it visible ) and change the Visibility to GONE in the onClick() method.
if you dont understand , post me your code and will let you know what changes to make.
