Listview- clicking on the title to show the description

Im doing Dream app on Android. I have a ListView view containing a title and description that are stored in separate TextView. I want the titles to be displayed in the listView view and only after clicking one of them to display the description. After pressing another title, I want the previous description to collapse and show another, attached to the given title.
I want to my notes look this way:
Android dream
This is my adapter class where I think I need to add a few lines to solve my problem
class SennikListAdapter extends BaseAdapter implements Filterable {
private ArrayList<Sennik> mOriginalValues; // Original Values
private ArrayList<Sennik> mDisplayedValues; // Values to be displayed
LayoutInflater inflater;
public SennikListAdapter(Context context, ArrayList<Sennik> mProductArrayList) {
this.mOriginalValues = mProductArrayList;
this.mDisplayedValues = mProductArrayList;
inflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return mDisplayedValues.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
private class ViewHolder {
RelativeLayout llContainer;
TextView titleOfDream, descriptionOfDream;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.customlayout, null);
holder.llContainer = (RelativeLayout) convertView.findViewById(R.id.llContainer);
holder.titleOfDream = (TextView) convertView.findViewById(R.id.titleTextView);
holder.descriptionOfDream = (TextView) convertView.findViewById(R.id.descriptionTextView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.titleOfDream.setText(mDisplayedValues.get(position).getTitleOfDream());
holder.descriptionOfDream.setText(mDisplayedValues.get(position).getDescriptionOfDream() + "");
return convertView;
}
I wanted to do something like this in getView method, but there is an error "Veriable 'holder' is accessed from within inner class, needs to be declered final". If i change to final still doesn't work
holder.titleOfDream.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (holder.descriptionOfDream.getVisibility() == View.GONE)
{
//expandedChildList.set(arg2, true);
holder.descriptionOfDream.setVisibility(View.VISIBLE);
}
else
{
//expandedChildList.set(arg2, false);
holder.descriptionOfDream.setVisibility(View.GONE);
}
}
});
Do you have any ideas how to do this? I checked so many tutorials but didn't find, and im sure it isn't difficult :(
Maybe this would be helpful
this is Fragment class
public class SennikFragment extends Fragment {
private List<String> fileName;
private List<String> fileContent;
private ArrayList<Sennik> sen = new ArrayList<Sennik>();
private SennikListAdapter adapter;
private EditText editText;
private ListView listView;
private AssetManager assets;
#Nullable

fileContent = new ArrayList<>();
editText=(EditText) view.findViewById(R.id.searchFilter);
listView=(ListView) view.findViewById(R.id.listView);
assets = getActivity().getAssets();
//dodanie do pola wyszukiwania obiektu nasłuchującego zmian w tekście
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if (adapter != null) {
adapter.getFilter().filter(s.toString());
} else {
Log.d("filter", "no filter availible");
}
}
#Override
public void afterTextChanged(Editable s) {
}
});
//uzupełnienie listy tytułów i opisów snu z folderu assets
try {
//Pobranie nazw wszystkich plików
String[] paths = assets.list("");
String text="";
/* Usunięcie z nazw plików ich rozszerzenia formatu */
for (String path : paths) {
if (path.equals("images") || path.equals("sounds") || path.equals("webkit"))
continue;
fileName.add(path.replace(".txt", " "));
InputStream is= assets.open(path);
int size=is.available();
byte[]buffer=new byte[size];
is.read(buffer);
is.close();
text=new String(buffer);
fileContent.add(text);
}
} catch (IOException ex) {
Log.e(TAG, "Bład podczas ładowania plików", ex);
}
//dodanie do listy z modelu Sennik tytułów i opisów snu
for(int i=0; i<fileName.size(); i++){
sen.add(new Sennik(fileName.get(i), fileContent.get(i)));
}
adapter=new SennikListAdapter((Context)getActivity(),sen);
listView.setAdapter(adapter);
return view;
}
}
this is description class
public class Sennik {
private String titleOfDream;
private String descriptionOfDream;
public Sennik(String titleOfDream, String descriptionOfDream) {
this.titleOfDream = titleOfDream;
this.descriptionOfDream = descriptionOfDream;
}
public String getTitleOfDream() {
return titleOfDream;
}
public void setTitleOfDream(String titleOfDream) {
this.titleOfDream = titleOfDream;
}
public String getDescriptionOfDream() {
return descriptionOfDream;
}
public void setDescriptionOfDream(String descriptionOfDream) {
this.descriptionOfDream = descriptionOfDream;
}
}
and my layouts:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:id="#+id/llContainer">
<TextView
android:id="#+id/titleTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:textSize="20dp"
android:textColor="#color/colorAccent"
android:text="TextView" />
<TextView
android:id="#+id/descriptionTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/titleTextView"
android:layout_centerHorizontal="true"
android:textColorHighlight="#color/colorPrimary"
android:textStyle="italic"
android:gravity="center"
android:textColor="#color/colorPrimary"
android:text="TextView" />
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:layout_width="match_parent"
android:layout_height="50dp"
android:id="#+id/searchFilter"></EditText>
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/searchFilter">
</ListView>
EDIT
problem solved!
I just add a line to my Adapter class to hide the description
holder.descriptionOfDream.setVisibility(View.GONE);
so the whole Adapter class look like:
class SennikListAdapter extends BaseAdapter implements Filterable {
private ArrayList<Sennik> mOriginalValues; // Original Values
private ArrayList<Sennik> mDisplayedValues; // Values to be displayed
LayoutInflater inflater;
public SennikListAdapter(Context context, ArrayList<Sennik> mProductArrayList) {
this.mOriginalValues = mProductArrayList;
this.mDisplayedValues = mProductArrayList;
inflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return mDisplayedValues.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
private class ViewHolder {
RelativeLayout llContainer;
TextView titleOfDream, descriptionOfDream;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.customlayout, null);
holder.llContainer = (RelativeLayout) convertView.findViewById(R.id.llContainer);
holder.titleOfDream = (TextView) convertView.findViewById(R.id.titleTextView);
holder.descriptionOfDream = (TextView) convertView.findViewById(R.id.descriptionTextView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.titleOfDream.setText(mDisplayedValues.get(position).getTitleOfDream());
holder.descriptionOfDream.setText(mDisplayedValues.get(position).getDescriptionOfDream() + "");
holder.descriptionOfDream.setVisibility(View.GONE);
return convertView;
}
And in Fragment class i use setOnItemClickListener method on listView (setOnClickListener doesn't work)
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
TextView descriptionOfDream= (TextView) view.findViewById(R.id.descriptionTextView);
if(descriptionOfDream.getVisibility()==view.GONE){
descriptionOfDream.setVisibility(view.VISIBLE);
}
else
{
descriptionOfDream.setVisibility(view.GONE);
}
}
});
So the whole Fragment class look like:
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_sennik, container, false);
// inicjalizacja pól
fileName = new ArrayList<>();
fileContent = new ArrayList<>();
editText=(EditText) view.findViewById(R.id.searchFilter);
listView=(ListView) view.findViewById(R.id.listView);
assets = getActivity().getAssets();
//dodanie do pola wyszukiwania obiektu nasłuchującego zmian w tekście
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if (adapter != null) {
adapter.getFilter().filter(s.toString());
} else {
Log.d("filter", "no filter availible");
}
}
#Override
public void afterTextChanged(Editable s) {
}
});
//uzupełnienie listy tytułów i opisów snu z folderu assets
try {
//Pobranie nazw wszystkich plików
String[] paths = assets.list("");
String text="";
/* Usunięcie z nazw plików ich rozszerzenia formatu */
for (String path : paths) {
if (path.equals("images") || path.equals("sounds") || path.equals("webkit"))
continue;
fileName.add(path.replace(".txt", " "));
InputStream is= assets.open(path);
int size=is.available();
byte[]buffer=new byte[size];
is.read(buffer);
is.close();
text=new String(buffer);
fileContent.add(text);
}
} catch (IOException ex) {
Log.e(TAG, "Bład podczas ładowania plików", ex);
}
//dodanie do listy z modelu Sennik tytułów i opisów snu
for(int i=0; i<fileName.size(); i++){
sen.add(new Sennik(fileName.get(i), fileContent.get(i)));
}
adapter=new SennikListAdapter((Context)getActivity(),sen);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
TextView descriptionOfDream= (TextView) view.findViewById(R.id.descriptionTextView);
if(descriptionOfDream.getVisibility()==view.GONE){
descriptionOfDream.setVisibility(view.VISIBLE);
}
else
{
descriptionOfDream.setVisibility(view.GONE);
}
}
});
return view;
}
}
Works excelent <3

First you need to create a class Extending LinearLayout and give some Expanding/collapsing
capabilities to It. Then define your description Textview as a child of that.
public class ExpandableLinearLayout extends LinearLayout {
private boolean expanded;
private int duration;
public ExpandableLinearLayout(Context context) {
super(context);
}
public ExpandableLinearLayout(Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
init(attrs);
}
public ExpandableLinearLayout(Context context, #Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(attrs);
}
#RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public ExpandableLinearLayout(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
init(attrs);
}
private void init(AttributeSet attributeSet) {
TypedArray customValues = getContext().obtainStyledAttributes(attributeSet, R.styleable.ExpandableLinearLayout);
duration = customValues.getInt(R.styleable.ExpandableLinearLayout_expandDuration, -1);
customValues.recycle();
}
public boolean isExpanded() {
return expanded;
}
public void setExpanded(boolean expanded) {
this.expanded = expanded;
}
public void toggle() {
if (expanded)
expandView(this);
else
hideView(this);
}
private void expandView(final View view) {
view.measure(WindowManager.LayoutParams.MATCH_PARENT
, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
final int targetHeight = view.getMeasuredHeight();
// Older versions of android (pre API 21) cancel animations for views with a height of 0.
view.getLayoutParams().height = 1;
view.setVisibility(View.VISIBLE);
Animation a = new Animation() {
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
view.getLayoutParams().height = interpolatedTime == 1
? targetHeight : (int) (targetHeight * interpolatedTime);
view.requestLayout();
}
#Override
public boolean willChangeBounds() {
return true;
}
};
if (duration == -1)
a.setDuration((int) (targetHeight / view.getContext().getResources().getDisplayMetrics().density * 1.5));
else
a.setDuration(duration);
view.startAnimation(a);
}
private void hideView(final View view) {
final int initialHeight = view.getMeasuredHeight();
Animation a = new Animation() {
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
if (interpolatedTime == 1) {
view.setVisibility(View.GONE);
} else {
view.getLayoutParams().height = initialHeight - (int) (initialHeight * interpolatedTime);
view.requestLayout();
}
}
#Override
public boolean willChangeBounds() {
return true;
}
};
if (duration == -1)
a.setDuration((int) (initialHeight / view.getContext().getResources().getDisplayMetrics().density * 1.5));
else
a.setDuration(duration);
view.startAnimation(a);
}
}
Just Inflate this class into your xml layout file and create descriotion textView inside of it.
Add The following Code snippet into your Adapter class to call that when An Item gets a Click. It will Expand/Collapse the LinearLayout with an Animaiton.
private void initializeClicks() {
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (expandableLinearLayout.isExpanded()) {
expandableLinearLayout.setExpanded(false);
expandableLinearLayout.toggle();
orderList.get(getAdapterPosition()).setExpanded(false);
} else {
expandableLinearLayout.setExpanded(true);
orderList.get(getAdapterPosition()).setExpanded(true);
expandableLinearLayout.toggle();
if(lastExpandedCardPosition!=getAdapterPosition() && recyclerView.findViewHolderForAdapterPosition(lastExpandedCardPosition)!=null){
((ExpandableLinearLayout)recyclerView.findViewHolderForAdapterPosition(lastExpandedCardPosition).itemView.findViewById(R.id.expandedLinearLayout)).setExpanded(false);
orderList.get(lastExpandedCardPosition).setExpanded(false);
((ExpandableLinearLayout)recyclerView.findViewHolderForAdapterPosition(lastExpandedCardPosition).itemView.findViewById(R.id.expandedLinearLayout)).toggle();
}
else if(lastExpandedCardPosition!=getAdapterPosition() && recyclerView.findViewHolderForAdapterPosition(lastExpandedCardPosition)==null){
orderList.get(lastExpandedCardPosition).setExpanded(false);
}
lastExpandedCardPosition = getAdapterPosition();
}
}
});
}
Finally call the Method above in your Clicklistenr like this:
holder.titleOfDream.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (holder.descriptionOfDream.getVisibility() == View.GONE)
{
expandableLinearLayout.setVisibility(View.VISIBLE);
expandableLinearLayout.setExpanded(true);
}
else
{
expandableLinearLayout.setVisibility(View.GONE);
expandableLinearLayout.setExpanded(false);
}
}
});
For a more detailed Explanation about this Method see this post on Medium.com.
And dont forget to give a clap to this post.

You have to call this method in your code`
holder.descriptionOfDream.requestLayout();
So basically, your new code looks like this
holder.titleOfDream.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (holder.descriptionOfDream.getVisibility() == View.GONE)
{
//expandedChildList.set(arg2, true);
holder.descriptionOfDream.setVisibility(View.VISIBLE);
holder.descriptionOfDream.requestLayout();
}
else
{
//expandedChildList.set(arg2, false);
holder.descriptionOfDream.setVisibility(View.GONE);
holder.descriptionOfDream.requestLayout();
}
}
});
Hope that helps.
Keep in mind that the holder variable must be final like below
final ViewHolder holder = null;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.customlayout, null);
holder.llContainer = (RelativeLayout) convertView.findViewById(R.id.llContainer);
holder.titleOfDream = (TextView) convertView.findViewById(R.id.titleTextView);
holder.descriptionOfDream = (TextView) convertView.findViewById(R.id.descriptionTextView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.titleOfDream.setText(mDisplayedValues.get(position).getTitleOfDream());
holder.descriptionOfDream.setText(mDisplayedValues.get(position).getDescriptionOfDream() + "");
return convertView;

Exoplayer not stopping after app closes in PagerAdapter

I have problem with Exoplayer to stopping after the app is closed down, or the fragment is changed from the BottomNavigationView, I get the data from my API that is cast to a Recyclerview/Adapter that handle the data, then the data with the images and video is gettting showed with a PagerAdapter.
I also tried in the fragment to set a onDestroy, but not working.

Recyclerview holder mixes on scroll

When scroll recyclerview some items mixes. After I add ads after every 15 items, holder get wrong data. Some items are vip items. I will change background color of these items. But when I scroll it dublicates mixes. How can I solve?
This is my adapter

}
public void setOnClickListener(View.OnClickListener listener) {
mView.setOnClickListener(listener);
}
}
I think problem onBindViewHolder function use wrong holder. ArrayList also return true value but on scroll it mixes.

You just have to add the corresponding else of the following if statement block.
if (car.getVip() == 1) {
holder.relativeLayout.setBackgroundColor(ContextCompat.getColor(mCtx, R.color.colorVip));
holder.imageViewVIP.setVisibility(View.VISIBLE);
} else {
holder.relativeLayout.setBackgroundColor(ContextCompat.getColor(mCtx, R.color.colorNormal));
holder.imageViewVIP.setVisibility(View.GONE);
}
This is inside your onBindViewHolder function where the view type is CONTENT_TYPE.
Hope that solves your problem.

Multiselection RecyclerView selects other items also

I want to implement a simple custom multiselection RecyclerView.
My problem is when I select the first CardView element in the screen, the tenth Card is also selected (When I select the second, the eleventh card is selected etc.). I have tried many different such as using `notifyItemChanged(pos) but I always end up to the same bug.
Here is the code if the my custom class.
public class StudentRecyclerAdapter extends RecyclerView.Adapter<StudentRecyclerAdapter.CustomViewHolder> {
private List<Student> studentListItemList;
private Context mContext;
private Students students;
private Set<Integer> studensToBeRemoved;
private List<Boolean> selected;
public StudentRecyclerAdapter(Context context, List<Student> studentListItemList, Students students) {
this.studentListItemList = studentListItemList;
this.mContext = context;
this.studensToBeRemoved = new HashSet<>();
this.students = students;
selected= new ArrayList<>();
for(int i=0;i<studentListItemList.size();i++)
selected.add(false);
}
View.OnClickListener clickListener = new View.OnClickListener() {
#Override
public void onClick(View view) {
CustomViewHolder holder = (CustomViewHolder) view.getTag();
int position = holder.getAdapterPosition();
Student studentListItem = studentListItemList.get(position);
Bundle extras = new Bundle();
extras.putInt("id", studentListItem.getId());
extras.putString("name", studentListItem.getName());
extras.putString("surname", studentListItem.getSurname());
extras.putLong("date", studentListItem.getLongBirthday());
extras.putString("photo", studentListItem.getImage());
Intent intent = new Intent(mContext, ProfileStudent.class);
intent.putExtras(extras);
mContext.startActivity(intent);
}
};
View.OnLongClickListener longClickListener = view -> {
final CustomViewHolder holder = (CustomViewHolder) view.getTag();
int pos = holder.getAdapterPosition();
if (!selected.get(pos)) {
holder.stud_card_view.setCardBackgroundColor(Color.GREEN);
studensToBeRemoved.add(studentListItemList.get(pos).getId());
selected.set(pos,true);
} else {
holder.stud_card_view.setCardBackgroundColor(Color.WHITE);
studensToBeRemoved.remove(studentListItemList.get(pos).getId());
selected.set(pos,false);
}
if (studensToBeRemoved.size() > 0)
students.onMethodCallback(true);
else
students.onMethodCallback(false);
StringBuilder stringBuilder= new StringBuilder();
for(Integer integer : studensToBeRemoved)
stringBuilder.append(integer).append(", ");
Toast.makeText(mContext,String.valueOf(pos)+ ": "+stringBuilder.toString(),Toast.LENGTH_LONG).show();
return true;
};
#Override
public CustomViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.student_list_row, null);
RecyclerView.LayoutParams lp = new RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
view.setLayoutParams(lp);
CustomViewHolder viewHolder = new CustomViewHolder(view);
return viewHolder;
}
#Override
public void onBindViewHolder(CustomViewHolder customViewHolder, int i) {
}
#Override
public void onBindViewHolder(CustomViewHolder customViewHolder, int i, List<Object> payload) {
if (payload.size() == 1) {
if ((boolean) payload.get(0)) {
customViewHolder.stud_card_view.setCardBackgroundColor(Color.GREEN);
studensToBeRemoved.add(studentListItemList.get(i).getId());
} else {
customViewHolder.stud_card_view.setCardBackgroundColor(Color.WHITE);
studensToBeRemoved.remove(studentListItemList.get(i).getId());
}
if (studensToBeRemoved.size() > 0)
students.onMethodCallback(true);
else
students.onMethodCallback(false);
} else {
Student studentListItem = studentListItemList.get(i);
Picasso.with(mContext).load(studentListItem.getImage())
.error(R.drawable.placeholder)
.placeholder(R.drawable.placeholder)
.into(customViewHolder.imageView);
customViewHolder.textView.setText(studentListItem.getName() + " " + studentListItem.getSurname());
customViewHolder.stud_card_view.setTag(customViewHolder);
customViewHolder.stud_card_view.setOnClickListener(clickListener);
customViewHolder.stud_card_view.setOnLongClickListener(longClickListener);
}
}
#Override
public int getItemCount() {
return (null != studentListItemList ? studentListItemList.size() : 0);
}
public void setFilter(ArrayList<Student> newList) {
studentListItemList = new ArrayList<>();
studentListItemList.addAll(newList);
notifyDataSetChanged();
}
public Set<Integer> getStudensToBeRemoved() {
return studensToBeRemoved;
}
public class CustomViewHolder extends RecyclerView.ViewHolder {
protected ImageView imageView;
protected TextView textView;
protected CardView stud_card_view;
public CustomViewHolder(View view) {
super(view);
this.imageView = view.findViewById(R.id.stud_list_pic);
this.textView = view.findViewById(R.id.stud_list_name);
this.stud_card_view = view.findViewById(R.id.stud_card_view);
}
}
}
PS. The payload check I have is because i have also implemented a selectAll() method (Which I call from the fragment host the RecyclerView) which uses the notifyItemRangeChanged() which is works properly.
Finally even the the 10th entry is also checked the studensToBeRemoved.add(studentListItemList.get(pos).getId()); for the 10th entry is never called actually. (The
Toast.makeText(mContext,String.valueOf(pos)+ ": "+stringBuilder.toString(),Toast.LENGTH_LONG).show();
in the end of onLongClickListener shows only the correct values every time ( e.g. when is select the first entry it shows "1: 1") although entry 10 is also selected). Finally if I select entry 10 the opposite happens (entry 1 is also selected).
Any Ideas whats going wrong? I can also provide some screenshots or more details if needed.
Thanks!

I managed to fix it. So here is the correct code in case someone wants to implement a simple RecyclerView with multi-selection. I hope it helps.
public class StudentRecyclerAdapter extends RecyclerView.Adapter<StudentRecyclerAdapter.CustomViewHolder> {
private List<Student> studentListItemList;

this.edit_button = view.findViewById(R.id.student_edit_btn);
edit_button.bringToFront();
}
}
}
The students.onMethodCallback() function informs the host fragment to show/hide the delete button. In order to select/deselect all element at once all you have to do is to call the setSelected(true/false) method.

How can I open original activities by clicking a listview item after filtering listview?

My code is working fine when it comes to clicking items. But the problem arises when I try to open activities after filtering listview. It always opens activity 1.
Here is my source code.
navigate.java
public class navigate extends Activity {
// Declare Variables

ListViewAdapter adapter;
EditText editsearch;
String[] rank;
String[] names;
int[] flag;

// Locate the ListView in listview_main.xml
list = (ListView) findViewById(R.id.listview);
for (int i = 0; i < rank.length; i++)
{

// Binds all strings into an array
arraylist.add(wp);
}
// Pass results to ListViewAdapter Class

How can I open different activities while clicking on listview items after I filter them.
This is the sample code I used. Although it doesn't provide the functionality to open original activities through intent ,just some forged up activity,so I'm trying to change that.

I think your adapter has problem, this below sample code of my application is extended from Filterable and work fine
