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 {
public static ProgressDialog progress;
public static List<DashListModel> dashRowList1 = new ArrayList<DashListModel>();
public static View footerView;
// #Bind(R.id.dashListView)
public static ListView dashListView;
int preCount = 2, scroll_Inc = 10, lastCount;
boolean flag = true;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.dashboard_fragment, container, false);
ButterKnife.bind(this, v);
setHasOptionsMenu(true);
progress = new ProgressDialog(getActivity());
dashListView = (ListView) v.findViewById(R.id.dashListView);
footerView = ((LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.dashboard_list_footer, null, false);
dashListView.addFooterView(footerView);
footerView.setVisibility(View.GONE);
dashRowList1.clear();
dashboardViewTask();
dashListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.d("onItemClick", "onItemClick <---- ");
Intent toPositionDetail = new Intent(getActivity(), PositionDetailScreenRefactor.class);
toPositionDetail.putExtra("id", dashRowList1.get(position).getDashId());
startActivity(toPositionDetail);
getActivity().overridePendingTransition(R.anim.trans_left_in, R.anim.trans_left_out);
}
});
final int totalJobCount = SessionStores.gettotalJobList(getActivity());
Log.e("totalJobCount", "totalJobCount----" + totalJobCount);
dashListView.setOnScrollListener(new EndlessScrollListener(getActivity(), dashListView, footerView));
return v;
}
public void dashboardViewTask() {
progress.setMessage("Please Wait. It is Loading..job orders....");
progress.setCanceledOnTouchOutside(false);
progress.setCancelable(false);
progress.show();
// footerView.setVisibility(View.VISIBLE);
Map<String, String> params = new HashMap<String, String>();
Log.e("candidate_id", "candidate_id---->" + SessionStores.getBullHornId(getActivity()));
params.put("candidate_id", SessionStores.getBullHornId(getActivity()));
params.put("page", "1");
new DashBoardTask(getActivity(), params, dashListView, footerView);
// progress.dismiss();
}
#Override

}
}
DashListAdapter:
________________
public class DashListAdapter extends BaseAdapter {
public static ListView dashListView;
Context c;
private LayoutInflater inflater;
private List<DashListModel> dashRowList;
public DashListAdapter(Context c, List<DashListModel> dashRowList, ListView dashListView) {
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.

class adapter:
public class ChildrenAdapter extends ArrayAdapter<Child> {
private final Context context;
private final ArrayList<Child> childrenArrayList;
public ChildrenAdapter(Context context, ArrayList<Child> childrenArrayList) {
super(context, R.layout.row_child, childrenArrayList);
this.context = context;
this.childrenArrayList = childrenArrayList;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// 1. Create inflater
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// 2. Get rowView from inflater
View rowChildView = inflater.inflate(R.layout.row_child, parent, false);
// 3. Get the two text view from the rowView
TextView nameView = (TextView) rowChildView.findViewById(R.id.name);
TextView dateView = (TextView) rowChildView.findViewById(R.id.date);
TextView scoreView = (TextView) rowChildView.findViewById(R.id.score);
// 4. Set the text for textView
//String text = childrenArrayList.get(position).getNomEnfant())+" "+childrenArrayList.get(position).getNomEnfant();
nameView.setText(childrenArrayList.get(position).getNomEnfant()+" "+childrenArrayList.get(position).getPrenomEnfant());
dateView.setText("22/12/2012");
scoreView.setText(String.valueOf(childrenArrayList.get(position).getIdEnfant()));
scoreView.setBackgroundResource(R.drawable.circular_textview);
// 5. retrn rowView
return rowChildView;
}
}
Whene i click to the row of listview i get the "id" but how i can pass it to the popupMenu.
The solution: it just add settag(position) to imageview in getview, then :
public void showMenu(View v) {
PopupMenu popup = new PopupMenu(this, v);
popup.setOnMenuItemClickListener(this);
popup.inflate(R.menu.poupup_menu);
popup.show();
listView.performItemClick(v, (Integer) v.getTag(),listView.getItemIdAtPosition((Integer) v.getTag()));
}

You can use interface to communicate between them
In your adapter class, initialize
private OnItemSelectedListener mListener;
and add these methods
public void setOnItemClickLister(OnItemSelectedListener mListener) {
this.mListener = mListener;
}
//Creating an interface
public interface OnItemSelectedListener {
public void onItemSelected(String s);
}
in onClick function in adapter
use this
mListener.onItemSelected(id);
//id is your string
you can call it in MainActivity,
adapter.setOnItemClickLister(new OnItemSelectedListener() {
#Override
public void onItemSelected(String s) {
//you will get the string here, you can pass it as an argument in popup menu
}
});

On the adapter Side:
view.findViewById(R.id.menu_btn).setTag(id);
On the ListActivity Side:
public void showPopUp(View v){
currentId = v.getTag().toString();
PopupMenu popupMenu=new PopupMenu(this,v);
popupMenu.setOnMenuItemClickListener(ListActivity.this);
MenuInflater inflater=popupMenu.getMenuInflater();
inflater.inflate(R.menu.my_pop_up,popupMenu.getMenu());
popupMenu.show();
}
On XML side:
<ImageButton android:id="#+id/menu_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/ic_overflow"
android:layout_marginStart="10dp"
android:layout_marginEnd="20dp"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true"
android:onClick="showPopUp"/>
Note: onClick="showPopUp" is very critical here.
This should be helpful. Thank you.

}
but when it returned activity AddProductActivity,the images did not appear in gridview ,if i clicked the editorText to active the keyboard,the images appearing in the gridview. So i am puzzled,waiting for some suggestions, thanks!
image url :http://i61.tinypic.com/2ch9onq.png
actived keyboard image appearing: http://i61.tinypic.com/2l8uumc.png
if i used this getView() method in AddProductActivity,it works fine.
#Override
public View getView(final int position, View convertView, ViewGroup
parent)
{
if (convertView == null){
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(245, 150));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
}
else {
imageView = (ImageView) convertView;
}
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inJustDecodeBounds = false ;
bmOptions.inSampleSize = 4;
bmOptions.inPurgeable = true ;
Bitmap bitmap = BitmapFactory.decodeFile(selectImageUrls.get(position), bmOptions);
imageView.setImageBitmap(bitmap);
return imageView;
}
but it does not smooth when it transfored the imageurls back to AddProductActivity.

Try to replace adapter code.
public class SelectImageAdapter extends BaseAdapter {
Context mContext;
ViewHolder holder;
public SelectImageAdapter(Context context, ArrayList<String> imageList) {
// TODO Auto-generated constructor stub
mContext = context;
imageLoader = ImageLoader.getInstance();
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return selectImageUrls.size();
}
#Override

// TODO Auto-generated method stub
return null;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
holder = new ViewHolder();
convertView = LayoutInflater.from(mContext).inflate(R.layout.select_image, null);
holder.imageView = (ImageView) convertView.findViewById(R.id.select_images);
holder.spinner = (ProgressBar)convertView.findViewById(R.id.select_image_loading);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
//final ViewAnimator animator = (ViewAnimator)convertView.findViewById(R.id.animator);
imageLoader.displayImage("file://" + selectImageUrls.get(position),holder.imageView,
options, new SimpleImageLoadingListener() {
#Override
public void onLoadingStarted(String imageUri, View view) {
holder.spinner.setVisibility(View.VISIBLE);
//animator.setDisplayedChild(1);
}
#Override
public void onLoadingFailed(String imageUri, View view,
FailReason failReason) {
String message = null;
switch (failReason.getType()) {
case IO_ERROR:

break;
}
Toast.makeText(AddProductActivity.this, message,Toast.LENGTH_SHORT).show();
holder.spinner.setVisibility(View.GONE);
//animator.setDisplayedChild(0);
}
#Override
public void onLoadingComplete(String imageUri,
View view, Bitmap loadedImage) {
// Animation anim =
// AnimationUtils.loadAnimation(Sdcard.this,
// R.anim.push_left_in);
// imageView.setAnimation(anim);
// anim.start();
holder.spinner.setVisibility(View.GONE);
}
});
return convertView;
}
class ViewHolder {
ImageView imageView;
ProgressBar spinner;
}
}

I believe what is missing in the code is a call to notifyDataSetChanged() after the images are loaded (in onLoadingComplete() callback of the listener).
The way the above code is written, if notifyDataSetChanged() is called in onLoadingComplete(), it will solve the problem that you have.
However, calling notifyDataSetChanged() every time in that callback method, may degrade the performance significantly. The more images you have, the more the performance may drop.
If you do observe performance drop by doing the above, to solve it, I would suggest using an image refresh helper mechanism. This way you can either call notifyDataSetChanged():
after n images have been loaded
or after every t seconds has passed
I hope the information above helps you.

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.
Problem which i have faced ::
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.... ;)

Contextual menu. (Android, SherlockActionbar)

I really need your help. First of all I created a Customfragment which extends from SherlockListFragment. I implemented my own Listviewrow design and for this reason I created my own BaseAdapter. A listview row contains a checkbox and some textviews.
My goal was to build a listview which looks and interacts like the Gmail app.
That means if a user clicks on the checkbox the action contextual menu will be activated.
So these are my classes:
public class PurchasesOpenFragment extends SherlockListFragment implements
OnItemClickListener, ListViewContextualMenuListener {
private ActionMode actionMode;
ArrayList<String> purchases = new ArrayList<String>();
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
purchases.add("Temp 1");
purchases.add("Temp 5");
purchases.add("Temp 2");
purchases.add("Temp 3");
purchases.add("Temp 4");
purchases.add("Temp 6");
purchases.add("Temp 7");
PurchaseOpenAdapter purchaseAdapter = new PurchaseOpenAdapter(
getActivity().getBaseContext(), purchases);
setListAdapter(purchaseAdapter);
purchaseAdapter.setOnListViewContextualMenuListener(this);
return super.onCreateView(inflater, container, savedInstanceState);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
getListView().setOnItemClickListener(this);
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Toast toast = Toast.makeText(getActivity(),
"Show details of element with id: " +arg3,Toast.LENGTH_SHORT);
toast.show();
}
private final class ModeCallback implements ActionMode.Callback {
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
// Create the menu from the xml file
MenuInflater inflater = getSherlockActivity()
.getSupportMenuInflater();
inflater.inflate(R.menu.context_test, menu);
return true;
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
// Here, you can checked selected items to adapt available actions
return false;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
// Destroying action mode, let's unselect all items
for (int i = 0; i < getListView().getAdapter().getCount(); i++)
getListView().setItemChecked(i, false);
if (mode == actionMode) {
actionMode = null;
}
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
long[] selected = getListView().getCheckedItemIds();
Toast toast = Toast.makeText(getActivity(), "elements selected: "
+ selected.length, Toast.LENGTH_SHORT);
toast.show();
if (selected.length > 0) {
for (long id : selected) {
toast = Toast.makeText(getActivity(), "element selected with id: " + id,
Toast.LENGTH_SHORT);
toast.show();
}
}
mode.finish();
return true;
}
};
public void closeContextualMenu() {
if (actionMode != null) {
actionMode.finish();
actionMode = null;
}
}
/**
*
*/
#Override
public void onItemCheckBoxChanged(int position, boolean checkState) {
Toast toast = Toast.makeText(getActivity(), "pos: " + position
+ " check: " + checkState, Toast.LENGTH_SHORT);
toast.show();
getListView().setItemChecked(position, checkState);
int amountOfCheckedElements = getListView().getCheckedItemIds().length;
if (amountOfCheckedElements > 0) {
if (actionMode == null) {
actionMode = getSherlockActivity().startActionMode(
new ModeCallback());
}
actionMode.setTitle(amountOfCheckedElements + " selected");
return;
} else {
if (actionMode != null) {
actionMode.finish();
}
}
}
}
2nd class:
public class PurchaseOpenAdapter extends BaseAdapter implements OnClickListener {
private Context context;
private ArrayList<String> purchases;
private static LayoutInflater inflator;
private ListViewContextualMenuListener contextualListener;
public PurchaseOpenAdapter(Context context, ArrayList<String> purchases) {
this.context = context;
this.purchases = purchases;
inflator = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

holder.checkBox.setOnClickListener(this);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
// TODO only temp data
String temp = purchases.get(position);
holder.tvDate.setText("01.01.2001");
holder.tvTitle.setText(temp);
holder.tvSupermarket.setText("Spar");
holder.tvArticleAmount.setText("20 Articles");
return convertView;
}
#Override
public boolean hasStableIds() {
return true;
}
public void setOnListViewContextualMenuListener(
ListViewContextualMenuListener l) {
contextualListener = l;
}
#Override
public void onClick(View v) {
CheckBox cb = (CheckBox) v;
Toast toast = Toast
.makeText(context, "Checkboxstate of element with positon: "
+ v.getTag() + " check state: " + cb.isChecked(),
Toast.LENGTH_SHORT);
toast.show();
contextualListener.onItemCheckBoxChanged(Integer
.parseInt(cb.getTag().toString()),
cb.isChecked());
}
static class ViewHolder {
TextView tvDate;
TextView tvTitle;
TextView tvSupermarket;
TextView tvArticleAmount;
CheckBox checkBox;
}
}
As you can see here I used implemented the OnClickMethod for the checkbox in the PurchaseOpenAdapter.
To inform the PurchaseOpenFragment that the state of a checkbox changed I created my own Listener (onItemCheckBoxChanged).
So now i come to describtion of my problem:
I click on the checkbox and the contextual menu appears but checkbox is not checked but if I check the state of the checkbox everything is alright (id and isChecked() are correct).
If I close the contextual menu the checkbox is checked.
If I click on the same checkbox again, the id is completely wrong.
If I remove the listener execution in the adapter class, the checkboxes work correctly.
Hopefully someone can help me. Maybe there is another way to inform the listfragment class.
Thank you in advance!
