Get selected item position of RecyclerView

I am trying to get position of the clicked item in RecyclerView. In adapter class, I am trying to create intent and send clicked item's contents. Also I created popup menu for two option. It is in adapter class too. onBindViewHolder position is works for puting contents in the rows of RecyclerView. However I couldn't reach that position from outside of method.
This is adapter class.
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> implements PopupMenu.OnMenuItemClickListener {
public ArrayList<MovieModel.Results> resultList;
public Context context;
public RecyclerViewAdapter(ArrayList<MovieModel.Results> list, Context context) {
this.resultList = list;
this.context = context;
}
public class ViewHolder extends RecyclerView.ViewHolder {
ImageView posterImage;
ImageView addIcon;
TextView movieName;
TextView date;
TextView overview;
public ViewHolder(#NonNull View itemView) {
super(itemView);
posterImage = itemView.findViewById(R.id.movie_poster);
addIcon = itemView.findViewById(R.id.addImage);
movieName = itemView.findViewById(R.id.movieNameText);
date = itemView.findViewById(R.id.dateText);
overview = itemView.findViewById(R.id.overviewText);
}
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.movie_list_2, parent, false);
return new ViewHolder(itemView);
}
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, int position) {
if (position < getItemCount()) {
String title = resultList.get(position).getTitle();
String date = resultList.get(position).getRelease_date();
String overview = resultList.get(position).getOverview();
String posterPath = resultList.get(position).getPoster_path();
holder.movieName.setText(title);
holder.date.setText(date);
holder.overview.setText(overview);
if (posterPath == null) {
holder.posterImage.setImageDrawable(context.getDrawable(R.drawable.no_poster));
} else {
Glide.with(context).load(FeedActivity.BASE_PHOTO_URL + posterPath).into(holder.posterImage);
}
int finalPosition = position;
holder.addIcon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Toast.makeText(context, "You clicked : " + finalPosition, Toast.LENGTH_SHORT).show();
showPopup(v);
}
});
}
position++;
}
private void showPopup(View v) {
PopupMenu popup = new PopupMenu(context,v);
popup.setOnMenuItemClickListener(this);
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.menu, popup.getMenu());
popup.show();
}
#Override
public boolean onMenuItemClick(MenuItem item) {
// Here I need to position of clicked item in Recyclerview, and I will get title, date etc.
int pos;
if(item.getItemId() == R.id.menuAdd){
// Find here to get position of clicked movie.
String title = resultList.get(pos).getTitle();
String date = resultList.get(pos).getRelease_date();
String overview = resultList.get(pos).getOverview();
String posterpath = resultList.get(pos).getPoster_path();
Intent intent1 = new Intent(context,ListActivity.class);
intent1.putExtra("title",title);
intent1.putExtra("date",date);
intent1.putExtra("overview",overview);
intent1.putExtra("posterpath",posterpath);
context.startActivity(intent1);
return true;
}
else if(item.getItemId() == R.id.menuShowDetails){
int movieId = resultList.get(pos).getMovieId();
Intent intent1 = new Intent(context, MovieDetails.class);
intent1.putExtra("movie_id",movieId);
context.startActivity(intent1);
return true;
}
return false;
}
#Override
public int getItemCount() {
return resultList.size();
}
}

You can use the ViewHolder's getAdapterPosition() to retrieve the item's position within an interface method. Then store the clicked position in a member variable.
Additionally, there shouldn't be a need to call position++ from within your onBindViewHolder.
// Create a member variable to store the clicked position
public int clickedPos = -1;
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, int position) {
// ...
holder.addIcon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// When you're inside the click listener interface,
// you can access the position using the ViewHolder.
// We'll store the position in the member variable in this case.
clickedPos = holder.getAdapterPosition();
}
});
// Remove the 'position++' call as the position should already be handled without explicitly updating it.
}
#Override
public boolean onMenuItemClick(MenuItem item) {
// You can use clickedPos here to perform whatever tasks you need.
// ...
}

How to get gridview multiple positions and store into array variable

Now I am displaying images in grid-view, it working fine. In that grid-view i am going to select few images, i want store selected multiple images position in array variable (example: if i select position 1, 4 ,10. i want that particular position id and i want to store it array like 1,4,10,15,). I will put my activity and adapter code below. Thank you in advance.

It's simple. You can use SparseBooleanArray for this purpose. Just add the following methods as is in your adapter:
public void toggleSelection(int item) {
if (selectedItems.get(item, false)) {
selectedItems.delete(item);
} else {
selectedItems.put(item, true);
}
notifyDataSetChanged();
}
public void setSelectedItems(List<Object> objects) {
if (objects != null) {
for (Object object : objects) {
toggleSelection(object.getId());
}
notifyDataSetChanged();
}
}
public void clearSelections() {
selectedItems.clear();
notifyDataSetChanged();
}
public int getSelectedItemCount() {
return selectedItems.size();
}
public List<Integer> getSelectedItems() {
List<Integer> items =
new ArrayList<Integer>(selectedItems.size());
for (int i = 0; i < selectedItems.size(); i++) {
items.add(selectedItems.keyAt(i));
}
return items;
}
Use the set selection method to store the selected status of your item.
Don't forget to initialize SparseBooleanArray in your constructor.
SparseBooleanArray SparseBooleanArray = new SparseBooleanArray();
After that, use toggleSelection(position); to change the selected status of an item, then after performing selections, call getSelectedItem() to get the selected items in an array.

// create an Arraylist and add the selected position in a list
List <int> selectedArray = new ArrayList<>();
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
int click = (int) parent.getItemAtPosition(position);
selectedArray.add(click);
}

Dynamic ListView issue on Android

Currently I am working on an Android app and use parse as backend where I have created a ListView of nearby places dynamically. But I face the following design issue: When the user clicks on a place, a view must appear under the clicked item.
And I have faced a problem with grouping the place, as you can see in figure 1, there are many branches for HSBC bank. In which case they are under HSBC.
I have tried expandable ListView before, but it does not give much customization for child view , just simple one.
my BaseAdapter:
import java.util.ArrayList;

private ArrayList<AnywallPost> arraylist;
public ListViewAdapter(Context context,
List<AnywallPost> AnywallPostlist) {
this.context = context;
this.AnywallPostlist = AnywallPostlist;
inflater = LayoutInflater.from(context);
this.arraylist = new ArrayList<AnywallPost>();
this.arraylist.addAll(AnywallPostlist);

// ... set the image here
// ... set the number of branches here
break;

branch = (AnywallPost) getItem(position);

holder.distance.setText(branch.getDis());
holder.b.setText(branch.getbranch());
imageLoader.DisplayImage(branch.getimg(),
holder.logo);
// ... set values for all the expanded view widgets too
break;
}
I have used this code to get image from parse and I add it to AnywallPost
ParseFile image = (ParseFile) country.get("image");
AnywallPost map = new AnywallPost();
map.setimg(image.getUrl());
then, I used this code to load the image and it worked fine
imageLoader.DisplayImage(AnywallPostlist.get(position).getimg(),
holder.logo);

Here is my idea:
You will have two layouts, a brief one with the name & distance, and an expanded one with the name & distance plus all the details.
The brief layout will have a view type of 0, and the expanded layout will have a view type of 1.
When you click on the item, you set a flag in the list model to indicate that the view has switched from brief view to long view. So you should see the view switch. If you click on an expanded view, it will revert to brief view.
I don't have a way to test this, but here is how I think the code will look:
public class ListViewAdapter extends BaseAdapter {
// Declare Variables
Context context;
LayoutInflater inflater;
//ImageLoader imageLoader;
private List<AnywallPost> AnywallPostlist = null;
private ArrayList<AnywallPost> arraylist;
/** this array holds a flag for each item to show if it is in brief view more or expanded view mode*/
private boolean[] expandedView;
public ListViewAdapter(Context context,
List<AnywallPost> AnywallPostlist) {
this.context = context;
this.AnywallPostlist = AnywallPostlist;
inflater = LayoutInflater.from(context);
this.arraylist = new ArrayList<AnywallPost>();
this.arraylist.addAll(AnywallPostlist);
this.expandedView = new boolean[AnywallPostlist.size()];
}
public class ViewHolder {
TextView distance;
TextView name;
// ... add all your expanded view fields here too
}
#Override
public int getCount() {
return AnywallPostlist.size();
}
#Override
public int getViewTypeCount() {
return 2; // brief & expanded
}
#Override
public int getItemViewType(int position) {
return expandedView[position] ? 1 : 0;
}
#Override
public Object getItem(int position) {
return AnywallPostlist.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public View getView(final int position, View view, ViewGroup parent) {
final ViewHolder holder;
final View row=view;
if (view == null) {
holder = new ViewHolder();
int layout = expandedView[position] ? R.layout.user_custom_expanded : R.layout.user_custom;
view = inflater.inflate(layout, parent, false);
// Locate the TextViews in listview_item.xml
holder.distance = (TextView) view.findViewById(R.id.disView);
holder.name = (TextView) view.findViewById(R.id.nameView);
if (expandedView[position]) {
// ... locate all the expanded view widgets too
}
view.setTag(holder);
} else {
// because the view type is determined by expandedView[position], the correct layout will be recycled here
holder = (ViewHolder) view.getTag();
}
// Set the results into TextViews
holder.name.setText(AnywallPostlist.get(position).getText());
holder.distance.setText(AnywallPostlist.get(position).getDis());
if (expandedView[position]) {
// ... set all the values for your expanded view too
}
//Listen for ListView Item Click
view.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
if (expandedView[position]) {
// this is expanded view so toggle it back to brief view
expandedView[position] = false;
} else {
// clear any expanded views elsewhere
expandedView = new boolean[AnywallPostlist.size()];
// toggle brief view to expanded
expandedView[position] = true;
}
// forces the ListView to refresh and convert the brief view into an expanded view and vice versa.
ListViewAdapter.this.notifyDataSetChanged();
// Toast.makeText(context,AnywallPostlist.get(position).getText(), Toast.LENGTH_LONG).show();
}
});
if (expandedView[position]) {
// ... add all your event listeners for the expanded view widgets
}
return view;
}
}
You can also add a toggle button with expand/collapse indicator to the view to control the expand/collapse so you don't click anywhere on the view to change it.
You can do this with an ExpandableListView if you want, you just need to change to an ExpandableListAdapter and do your layouts a little differently.

Here is some code to make a heterogeneous list:
Take a really good look at the constructor to see how I divided up the branches by bank them strung them all together into one big list.
The list is just an Object array, so you figure out what the item is like this:
If it's a Bank, then well, it's a bank.
If it's an AnywallPost and expandedView[position] == false then it's a branch, brief view
If it's an AnywallPost and expandedView[position] == true then it's a branch, expanded view

How to add a new set of items in a sliding menu?

I want to add another block, or set, or whatever it is called, of items in my sliding menu but I can't figure out what to change to the code of the first... In my sliding menu I have 6 items, but I to have 4 items to the first title, and then, another title, and another 2 items.. but i can't figure out what do I have to change to my first block code..

Thanks again !

I assume you want to achieve something similar to what is in the following picture:
You will have to modify your list adapter(NsMenuAdapter) to support two types of view - item and title where item is clickable and title is just kind of group header. Adapter should takes array/list of objects and every object should have type attribute. This will probably complicate a little OnItemClickListener.
I'm posting my example of that kind list adapter. In my case I created NavigationDrawerItem model to hold information about item type, item 'clickability' and what action should be triggered after item get clicked.
public class NavigationDrawerAdapter extends ArrayAdapter<NavigationDrawerItem> {
private static final String TAG = "NavigationDrawerAdapter";
public NavigationDrawerAdapter(Context context, int resource, NavigationDrawerItem[] objects) {
super(context, resource, objects);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (null == convertView) {
int itemType = getItemViewType(position);
if (NavigationDrawerItem.TYPE_TITLE == itemType) {
convertView = View.inflate(getContext(), R.layout.item_title_navigation_drawer, null);
} else if (NavigationDrawerItem.TYPE_ITEM_UNDER_TITLE == itemType) {
convertView = View.inflate(getContext(), R.layout.item_under_title_navigation_drawer, null);
} else {
Log.e(TAG, "Returning default title view - Invalid drawer item type" + itemType);
convertView = View.inflate(getContext(), R.layout.item_title_navigation_drawer, null);
}
}
TextView tv = (TextView) convertView.findViewById(R.id.text);
tv.setText(getContext().getString(getItem(position).stringRes));
return convertView;
}
#Override
public int getItemViewType(int position) {
return getItem(position).type;
}
#Override
public int getViewTypeCount() {
return NavigationDrawerItem.NUMBER_OF_ITEM_TYPES;
}
#Override
public boolean isEnabled(int position) {
return NavigationDrawerItem.isItemClickable(getItemViewType(position));
}
}
And the NavigationDrawerItem class:
public final class NavigationDrawerItem {
private static final String TAG = "NavigationDrawerItem";
// Types must have numbers from 0 to n without gaps.
public static final int TYPE_TITLE = 0;// nonclickable
public static final int TYPE_ITEM_UNDER_TITLE = 1;// clickabel
public static final int NUMBER_OF_ITEM_TYPES = 2;
public final int action;
public final String argument;
public final int type;
//Constructors etc.
public static final boolean isItemClickable(int itemType) {
if (TYPE_TITLE == itemType) {
return false;
} else if (TYPE_ITEM_UNDER_TITLE == itemType) {
return true;
} else {
Log.e(TAG, "Invalid item type " + itemType);
return false;
}
}
}

Get text content in EditText ListView after click button issue

I have a Listview of EditText and I need to get the String values of each edited row when I click a confirm button, but I don't know how.
I have tried to adapt some sample with no success ( I get always the default values and not the edited values).
My attempt is this
public class MyActivity extends Activity {
static int nItems;
ImageButton confirmButton;
ListView myList;
ListViewAdapterEditText adapterG1, adapterG2, adapterG3;
#Override
public void onCreate(Bundle savedInstanceState) {
.....
myList = (ListView) findViewById(R.id.listaG1);
myList.setItemsCanFocus(true);
adapterG1 = new ListViewAdapterEditText();
myList.setAdapter(adapterG1);
}
OnClickListener mConfirmButtonListener = new OnClickListener() {
public void onClick(View v) {
ArrayList a1 = adapterG1.getItems();
for (int i = 0; i < nItems; i++) {
System.out.println(a1.get(i)
+ "\n\n");
}
};
public class ListViewAdapterEditText extends BaseAdapter {
private LayoutInflater mInflater;
public ArrayList myItems = new ArrayList();
ListItem listItem;
public ListViewAdapterEditText() {
mInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
for (int i = 0; i < nItems; i++) {
listItem = new ListItem();
listItem.caption = "Caption" + i;
myItems.add(listItem);
}
notifyDataSetChanged();
}
public int getCount() {
return myItems.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public ArrayList<String> getItems() {
ArrayList<String> items = new ArrayList<String>();
for (int i = 0; i < nItems; i++) {
ListItem li = (ListItem) myItems.get(i);
items.add(li.getCaption());
}
return items;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.list_item_row,
null);
holder.caption = (EditText) convertView
.findViewById(R.id.ItemCaption);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
// Fill EditText with the value you have in data source
holder.caption.setText(((ListItem) myItems.get(position)).caption);
// holder.caption.setText(myItems.get(position).caption);
holder.caption.setId(position);
// we need to update adapter once we finish with editing
holder.caption
.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
final int position = v.getId();
final EditText Caption = (EditText) v;
((ListItem) myItems.get(position)).caption = Caption
.getText().toString();
}
}
});
return convertView;
}
class ViewHolder {
EditText caption;
}
class ListItem {
String caption;
public String getCaption() {
return caption;
}
}
}
}
Could someone help me to solve this problem?

Are you sure your OnFocusChangeListener is called? If you edit the text in EditText then tap the confirm button, this listener will not be called in touch mode since the focus is still on the EditText.
Update: Consider the situation you edited the text in a EditText while didn't confirm and scrolled the ListView so that the item view is recycled, I'm not sure what is your preferred way, but if you want store the edited data, you can use setRecyclerListener(android.widget.AbsListView.RecyclerListener) to get notified when a item view is recycled so you can saved the edit result. To save the result of EditText showing on screen, you use methods like getChildAt to get item views visible on screen then get the EditText's text.
Update2: Another better and clean way is use TextWatcher and addTextChangeListener, this will notifies you when the text in EditText is changed.
Update3: I just write the following sample and test it, and it works on my phone. :)
Update4: I removed the previous code cause its performance is bad and creates a lot objects, you can check the following full sample instead:
Activity code :

I usually follow a simpler technique
public class Item_Adapter extends BaseAdapter {
private String[] Val;
public Item_Adapter () {
Val= new String[nItems];
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
///bla bla
holder.caption
.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
final int position = v.getId();
final EditText Caption = (EditText) v;
((ListItem) myItems.get(position)).caption = Caption
.getText().toString();
Val[position]= Caption
.getText().toString();
}
}
});
///bla bla
return convertView;
}
/////most important returning your array so you can use it in the Activity
public String[] getVal() {
return Val;
}
