Cannot click on item's view inside RecyclerView

I want to show a popup menu for each item of a RecyclerView when a button is clicked.
My Adapter:
public class SearchResultRecyclerViewAdapter extends RecyclerView.Adapter<SearchResultRecyclerViewAdapter.ViewHolder> {
public SearchResultRecyclerViewAdapter(ArrayList<BookModel> bookModels, Context context) {
this.bookModels = bookModels;
this.context = context;
}
ArrayList<BookModel> bookModels;
Context context;
#NonNull
#NotNull
#Override
public ViewHolder onCreateViewHolder(#NonNull #NotNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_book,parent,false);
ViewHolder holder = new ViewHolder(view);
return holder;
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
Log.d("aa", bookModels.get(position).getThumbnailLink());
Glide.with(context)
.asBitmap()
.load(bookModels.get(position).getThumbnailLink())
.into(holder.coverImage);
holder.name.setText(bookModels.get(position).getName());
holder.author.setText(bookModels.get(position).getAuthor());
holder.category.setText(bookModels.get(position).getCategories().toString());
holder.maturity.setText(bookModels.get(position).getMaturityRating());
holder.desc.setText(bookModels.get(position).getDesc());
holder.option.setOnClickListener(new View.OnClickListener() { ///////////// here
#Override
public void onClick(View v) {
//show popup
Log.d("ItemOption","Clicked");
}
});
if (position+1 == bookModels.size()){
holder.divider.setVisibility(View.GONE);
}
}
#Override
public int getItemCount() {
return bookModels.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
RoundedImageView coverImage;
TextView name;
TextView author;
TextView desc;
TextView category;
TextView maturity;
ImageView divider;
Button option;
RelativeLayout root;
public ViewHolder(#NonNull #NotNull View itemView) {
super(itemView);
coverImage = itemView.findViewById(R.id.cover_book_item_imageview);
name = itemView.findViewById(R.id.name_book_item_textview);
author = itemView.findViewById(R.id.author_book_item_textview);
desc = itemView.findViewById(R.id.desc_book_item_textview);
category = itemView.findViewById(R.id.category_book_item_textview);
maturity = itemView.findViewById(R.id.maturity_book_item_textview);
divider = itemView.findViewById(R.id.divider_book_item_imageview);
option = itemView.findViewById(R.id.option_book_item_button);
root = itemView.findViewById(R.id.root);
}

when the item's view is clicked nothing happens. I've done the same exact thing before with no problem I don't know what I'm missing here.
EDIT:
as #anemomylos mentioned this might be a click issue. in this layout there is a lot of Views that will be Gone in order to RecyclerView shows up. RecyclerViews don't register any clicks themselves so I'm not sure if it's being blocked by another view or not, is there any way to know what is blocking the click? I don't have any android:clickable="true" and I made sure that all Views before RecyclerView are Gone and not Invisible

Why Custom ArrayAdapter not showing TextView in a ListView

I have made a custom ArrayAdapter and tried to add the another TextView "Breed" of the animals, but when i execute the program , its not showing the Breed. Where am i doing wrong ? I am scratching my head since long. please help where is the mistake ?
MainActivity.Java
public class MainActivity extends AppCompatActivity {
ListView simpleList;
ArrayList<Item> animalList=new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
simpleList = (ListView) findViewById(R.id.simpleListView);
animalList.add(new Item("Lion",R.drawable.lion,"Khatarnak"));
animalList.add(new Item("Tiger",R.drawable.tiger,"Fudu"));
animalList.add(new Item("Monkey",R.drawable.monkey,"Lallu"));
animalList.add(new Item("Elephant",R.drawable.elephant,"Jabardast"));
animalList.add(new Item("Dog",R.drawable.dog,"ItemDog"));
animalList.add(new Item("Cat",R.drawable.cat,"MeeMee"));
MyAdapter myAdapter=new MyAdapter(this,R.layout.list_view_items,animalList);
simpleList.setAdapter(myAdapter);
}
}
MyAdapter.Java
public class MyAdapter extends ArrayAdapter<Item> {
ArrayList<Item> animalList = new ArrayList<>();

textView.setText(animalList.get(position).getAnimalName());
imageView.setImageResource(animalList.get(position).getAnimalImage());
breedView.setText(animalList.get(position).getBreed());
return v;
}

This is most likely a problem with the linear layout for each item. The orientation is horizontal, which lays each view one after the other horizontally. The problem is that the text view for the animal type has a width of fill_parent leaving no space for the breed view. If you change it to wrap_content it'll probably work for some of the cases, but might not work with everything.
In any case I think this is a problem with the views' positions and sizes. Try and move them around. Perhaps even a simple change would be placing them vertically:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/imageView"
android:layout_width="50dp"
android:layout_height="50dp"
android:padding="5dp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/textView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Demo"
android:textColor="#000" />
<TextView
android:id="#+id/breed"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Breed"
android:textColor="#000" />
</LinearLayout>
</LinearLayout>
There's perhaps a more efficient way of doing this, but this is just an example. The inner linear layout places one text view on to of the other.
PS: your getCount method is not really doing anything. You can remove it.

replace your layout with my code your issue will resolve.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"

Update Listview in android

I am trying to create an activity where the user can create some recipe and input the ingredients. every time the user enters an ingredient, it should be added to a listview. The issue I am having here is that the first input is the only one that is added to the listview not the others.
Here is the layout script:
<?xml version="1.0" encoding="utf-8"?><ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".Activities.AddActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="226dp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="8dp"
android:orientation="vertical">
<EditText
android:id="#+id/Name_ET"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/recipe_name" />
<EditText
android:id="#+id/ServingsNbr_ET"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/number_of_servings" />
<EditText
android:id="#+id/PrepTime_Et"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/preparation_time" />
<EditText
android:id="#+id/Calories_ET"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/calories" />
</LinearLayout>
<LinearLayout
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="36dp"
android:text="#string/ingredients"
android:textSize="26sp"
android:textAlignment="center"
android:textStyle="bold"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText
android:id="#+id/new_ing"
android:layout_width="0dp"
android:layout_weight="9"
android:layout_height="36dp" />
<ImageView
android:id="#+id/add_ingredient_btn"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="36dp"
android:src="#drawable/round_add_circle_outline_black_36dp"/>
</LinearLayout>
<ListView
android:id="#+id/ingredient_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"></ListView>
</LinearLayout>
</LinearLayout>
And the logic behind it :
public class AddActivity extends AppCompatActivity {
private ListView added_ing;
private IngredientAdapter adapter;
private ArrayList<String> ingredients = new ArrayList<String>();
private EditText new_ing;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add);
adapter = new IngredientAdapter(AddActivity.this,ingredients);
added_ing = findViewById(R.id.ingredient_list);
added_ing.setAdapter(adapter);
new_ing = findViewById(R.id.new_ing);
ImageView add_ingredien = findViewById(R.id.add_ingredient_btn);
add_ingredien.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ingredients.add(new_ing.getText().toString());
Toast.makeText(AddActivity.this, new_ing.getText().toString(), Toast.LENGTH_SHORT).show();
adapter.notifyDataSetChanged();
}
});
}
public class IngredientAdapter extends ArrayAdapter<String> {
ArrayList<String> mNewIngredients;
public IngredientAdapter(Context context, ArrayList<String> objects) {
super(context, 0, objects);
mNewIngredients = objects;
}
public String getItem(int position) {
return mNewIngredients.get(position).toString();
}
public View getView(int position, View convertView, ViewGroup parent) {
String item = getItem(position);
if(convertView==null)
convertView = LayoutInflater.from(getContext()).inflate(R.layout.ingredient,parent,false);
TextView recipeName= convertView.findViewById(R.id.new_added_ingredient);
recipeName.setText(item);
return convertView;
}
}
}

Try to scroll down your list view, maybe in your item's layout, you set the layout_height = match_parent so you do not see the other inputs.

You need to add android:fillViewport="true" to your ScrollView
Also change all child LinearLayout height to wrap_content instead of match_parent
Try this
<?xml version="1.0" encoding="utf-8"?><ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:fillViewport="true"
android:layout_height="match_parent"

</ScrollView>

In your implementation of IngredientAdapter, you are using your own ArrayList mNewIngredients for the data instead of the collection in the ArrayAdapter. When you add new data into ingredients, it is not added to the adapter.
To make use of the collection implemented in ArrayAdapter for simplicity. The following is an example, with a view holder so that views can be reused.
public class IngredientAdapter extends ArrayAdapter<String> {
public IngredientAdapter(Context context, ArrayList<String> objects) {
super(context, 0, objects);
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if(convertView==null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.ingredient, parent, false);
holder = new ViewHolder();
holder.recipeName = convertView.findViewById(R.id.new_added_ingredient);
convertView.Tag = holder;
} else {
holder = (ViewHolder)convertView.Tag;
}
String item = getItem(position);
holder.recipeName.setText(item);
return convertView;
}
}
public class ViewHolder {
public TextView recipeName;
}
The data in the adapter is now backed by the internal collection. And in the activity, you should add the new data into adapter directly.
public class AddActivity extends AppCompatActivity {
private ListView added_ing;
private IngredientAdapter adapter;
// keep this if you need it for something else
// private ArrayList<String> ingredients = new ArrayList<String>();
private EditText new_ing;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add);
adapter = new IngredientAdapter(AddActivity.this,ingredients);
added_ing = findViewById(R.id.ingredient_list);
added_ing.setAdapter(adapter);
new_ing = findViewById(R.id.new_ing);
ImageView add_ingredien = findViewById(R.id.add_ingredient_btn);
add_ingredien.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// keep this if you need it for something else
// ingredients.add(new_ing.getText().toString());
// to add adata into the adapter
adapter.Add(new_ing.getText().toString());
Toast.makeText(AddActivity.this, new_ing.getText().toString(), Toast.LENGTH_SHORT).show();
adapter.notifyDataSetChanged();
}
});
}
}

Android Stackoverflow Errror: ViewGroup.jumpDrawablesToCurrentState

I have a problem. I got an Stackoverflow Error. I tried reduced the Layout and so on. But nothing worked.
I have a view pager and in the fragments are recyclerviews 4 times. (one in each). The inflater Code
View root = inflater.inflate(R.layout.content_main, container, false);
One Layout in Fragment for example:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.RecyclerView
android:id="#+id/list_view"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_margin="10dp"
android:layout_marginTop="15dp"
android:layout_height="wrap_content" />
And this is the Layout for the ReclerView Item
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
android:id="#+id/cv"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_margin="20dp"
android:clickable="true"
android:background="?attr/selectableItemBackground"
android:layout_width="match_parent"

One Layout has a Relative Layout but it works before I made some changes:

Captureing View Table is not possible because app is going down before it changes the layout.
Bitmaps are scaled.
Here is my Adapter:
public class DefaultAdapter extends RecyclerView.Adapter<DefaultAdapter.SongViewHolder> {
private Context con;
private List<String> names;
boolean useplaylist;
// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public static class SongViewHolder extends RecyclerView.ViewHolder {
CardView cv;
TextView title;
SongViewHolder(View itemView) {
super(itemView);
cv = (CardView)itemView.findViewById(R.id.cv);
title = (TextView)itemView.findViewById(R.id.album_name);
}
}
// Provide a suitable constructor (depends on the kind of dataset)
public DefaultAdapter(Context context,List<String> names,boolean playlist) {
con = context;
this.names = names;
useplaylist = playlist;
}
// Create new views (invoked by the layout manager)
#Override
public SongViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.playlist_item, viewGroup, false);
SongViewHolder pvh = new SongViewHolder(v);
return pvh;
}
#Override
public void onBindViewHolder(SongViewHolder personViewHolder, int i) {
personViewHolder.title.setText(names.get(i));
}
// Return the size of your dataset (invoked by the layout manager)
#Override
public int getItemCount() {
return names.size();
}
#Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
}

Can somebody help me?

Problem solved.
I don't know where the Error was but maby it was an empty list or the ImageAssets wich I replaced with vector assets and activate the Libary in the Gradle.
For thoos who have the same problem in a viewpage: Deactivate all fragments and enable them single, to test where the error is.

Two views with different heights in a viewflipper on a gridview tile

I have a GridView which has a ViewFlipper in each tile. Each view in the ViewFlipper has a different size, but when the tile is flipped, both views are forced to the same size as the GridView column. What i've tried:
Googled
Set android:measureAllChildren to false on ViewFlipper(only works with ListView)
Left android:columnWidth unspecified
Made ViewFlipper root tag in grid tile layout file
grid_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="180dp" android:layout_height="150dp">
<ViewFlipper
android:layout_width="match_parent"
android:layout_height="match_parent"
android:measureAllChildren="false"
android:id="#+id/view_flipper_3"
>
<RelativeLayout
android:layout_width="180dp"
android:layout_height="150dp"
android:id="#+id/front2"
android:background="#088980"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/commitmentNumber"
android:textSize="25dp"
/>
</RelativeLayout>
<RelativeLayout
android:layout_width="220dp"
android:layout_height="190dp"
android:background="#000000"
android:id="#+id/back_2"

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:id="#+id/commitmentPartOne"
android:paddingBottom="5dp"
android:textSize="25sp"
android:text="Part One"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:text="Part Three"
android:layout_below="#+id/commitmentPartTwo"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
/>
</RelativeLayout>
</ViewFlipper>
</RelativeLayout>
fragment_with_gridview.xml:
<?xml version="1.0" encoding="utf-8"?>

android:layout_centerHorizontal="true"
android:numColumns="2"
android:gravity="center"
android:columnWidth="179dp"
android:stretchMode="columnWidth"
/>
</RelativeLayout>
GridViewAdapter.java:
public class SixCommitmentsGridAdapter extends BaseAdapter {
Context context;
String[] numbers;
public SixCommitmentsGridAdapter(Context context, String[] numbers) {
this.context = context;
this.numbers = numbers;
}
#Override
public int getCount() {
return numbers.length;
}
#Override
public Object getItem(int position) {
return numbers[position];
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view;
final ViewFlipper flipper;
TextView commitmentNumber;
if(convertView == null){
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.six_commitments_grid_item, parent, false);
}else{
view = convertView;
}
flipper = (ViewFlipper) view.findViewById(R.id.view_flipper_3);
commitmentNumber = (TextView) view.findViewById(R.id.commitmentNumber);
commitmentNumber.setText(numbers[position]);
flipper.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(position % 2 == 0 || position == 0){
AnimationFactory.flipTransition(flipper, AnimationFactory.FlipDirection.RIGHT_LEFT, 200);
}else {
AnimationFactory.flipTransition(flipper, AnimationFactory.FlipDirection.LEFT_RIGHT, 200);
}
}
});
return view;
}
}

Managed to achieve the same grid-style layout with my intented ViewFlipper effect using a StaggeredGridLayoutManager and a RecyclerView.

In Main RelativeLayout contain ViewFlipper, you set height and width!
set them "wrap_content"
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
maybe worked.
good luck.
Update
Use this library:
