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

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

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">

<LinearLayout

</LinearLayout>
<ListView

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"

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();
}
});
}
}

RecyclerView not populating, likely a silly adapter problem

I used a working RecyclerView as a template for another, but I made some sort of mistake in its implementation and I can't find it. Here is the code that initializes the view:
mMessageThreadList = new ArrayList<>();
mRecyclerView = findViewById(R.id.chat_list_recycler_view);
private void initRecyclerView() {
Log.d(TAG, "initRecyclerView Called");
//Initializes and sets up adapter
mAdapter = new ChatListRecyclerViewAdapter(mThreadList);
mRecyclerView.setAdapter(mAdapter);
Query query = mThreadCollection;
query.addSnapshotListener(new EventListener<QuerySnapshot>() {
#Override
public void onEvent(#Nullable QuerySnapshot queryDocumentSnapshots, #Nullable FirebaseFirestoreException e) {
for (DocumentChange documentChange : queryDocumentSnapshots.getDocumentChanges()) {
switch (documentChange.getType()) {
case ADDED:
Thread thread = documentChange.getDocument().toObject(Thread.class);
Log.d(TAG, "Last Message: " + thread.getLastMessage().getMessage());
mThreadList.add(thread);
mAdapter.notifyDataSetChanged();
}
}
}
});
}
Note that the print log statement in the SnapshotListener does contain a value when printed so the information is returning from Firebase, it's just not displaying. Which makes me think my problem is with my Adapter/Viewholder:
public class ChatListRecyclerViewAdapter extends RecyclerView.Adapter<ChatListRecyclerViewAdapter.ChatListViewHolder> {
private List<Thread> threadList;
ChatListRecyclerViewAdapter(List<Thread> threadList) {
this.threadList = threadList;
}
#NonNull
#Override
public ChatListViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.chat_list_row, parent, false);
return new ChatListViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull ChatListViewHolder holder, int position) {
// This method fills fields with data for each list item
Log.d(TAG, "onBindViewholder called");
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MMM hh:mm a");
final Thread thread = threadList.get(position);
char initial = thread.getPartnerName().charAt(0);
char uppercaseInitial = Character.toUpperCase(initial);
Log.d(TAG, thread.getLastMessage() + " " + thread.getPartnerID());
holder.partnerName.setText(thread.getPartnerName());
holder.authorInitial.setText(uppercaseInitial);
holder.lastMessageText.setText(thread.getLastMessage().getMessage());
holder.lastMessageTime.setText(simpleDateFormat.format(thread.getLastMessage().getTimestamp()));
}
#Override
public int getItemCount() {
return threadList.size();
}
//Viewholder stores the information about the layout and content of each list item, and serves as a template for each item of a RecyclerView
public class ChatListViewHolder extends RecyclerView.ViewHolder {
TextView partnerName;
TextView authorInitial;
TextView lastMessageText;
TextView lastMessageTime;
LinearLayout listTextHolder;
public ChatListViewHolder(View itemView) {
super(itemView);
partnerName = itemView.findViewById(R.id.partner_name);
authorInitial = itemView.findViewById(R.id.partner_initial);
lastMessageText = itemView.findViewById(R.id.last_message);
lastMessageTime = itemView.findViewById(R.id.last_message_time);
listTextHolder = itemView.findViewById(R.id.list_text_holder);
}
}
}

Seems like you have missed to add layout manager of RecyclerView. Would you please add this and try again
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(mLayoutManager);

Your recyclerview is not showing any data because the list in adapter is still empty. After fetching data from firebase you are adding to mThreadList, which is still with activity and not adapter. To update the list in adapter you can add a method in adapter class and pass the list to adapter and notifyDataseChanged there.
Activity:
//after firebase task...
mAdapter.updateData(mThreadList);
Adapter: add new method
void updateData(List<Thread> threadList){
this.threadList = threadList;
notifyDatasetChanged(); //notify adapter that new list is added
}

How to change the indicator color every different cardview?

This is the adapter :
public class OrderListAdapter extends RecyclerView.Adapter<OrderListAdapter.OrderListViewHolder> {
private ArrayList<OrderListModel> itemOrderList;
public OrderListAdapter(ArrayList<OrderListModel> itemOrderList) {
this.itemOrderList = itemOrderList;
}
#Override
public OrderListViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
View view = layoutInflater.inflate(R.layout.order_list_item, parent, false);
return new OrderListViewHolder(view);
}
#Override
public void onBindViewHolder(OrderListViewHolder orderListViewHolder, int position) {
orderListViewHolder.txtDate.setText(itemOrderList.get(position).getDate());
orderListViewHolder.txtOrderNumber.setText(itemOrderList.get(position).getOrderNumber());
orderListViewHolder.txtCustomerName.setText(itemOrderList.get(position).getCustomerName());
orderListViewHolder.txtProductStatus.setText(itemOrderList.get(position).getProductStatus());
orderListViewHolder.txtNotes.setText(itemOrderList.get(position).getNotes());
}
#Override
public int getItemCount() {
return (itemOrderList != null) ? itemOrderList.size() : 0;
// return itemOrderList.size();
}
public class OrderListViewHolder extends RecyclerView.ViewHolder{
private TextView txtDate, txtOrderNumber, txtCustomerName, txtProductStatus,
txtNotes;
public OrderListViewHolder(View itemView) {
super(itemView);
txtDate = (TextView) itemView.findViewById(R.id.txt_order_date);
txtOrderNumber = (TextView) itemView.findViewById(R.id.txt_order_number);
txtCustomerName = (TextView) itemView.findViewById(R.id.txt_customer_name);
txtProductStatus = (TextView) itemView.findViewById(R.id.txt_product_status);
txtNotes = (TextView) itemView.findViewById(R.id.txt_notes);
}
}
}
This is the main :
public class OrderListFragment extends Fragment {
private RecyclerView recyclerView;
private OrderListAdapter adapter;
private ArrayList<OrderListModel> OrderListArrayList;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_order_list, container, false);
getActivity().setTitle(R.string.title_mn_order_list);
addData();
recyclerView = (RecyclerView) view.findViewById(R.id.orderList_recycler_view);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this.getActivity());
recyclerView.setLayoutManager(layoutManager);
adapter = new OrderListAdapter(OrderListArrayList);
recyclerView.setAdapter(adapter);
return view;
}
void addData(){
OrderListArrayList = new ArrayList<>();
OrderListArrayList.add(new OrderListModel(
"4 Juli 2018 10:54",
"0001",
"Jopa",
"No",
"Notes"));
OrderListArrayList.add(new OrderListModel(
"4 Juli 2018 10:54",
"0001",
"Jopa",
"Yes",
"Notes"));
}
}
Do you have any idea how can i change it?

You must give an id to your ImageView say status
In OrderListViewHolder add in your declarations private ImageView status;
In OrderListViewHolder add status = (ImageView) itemView.findViewById(R.id.status);
In OrderListViewHolder add
if (itemOrderList.get(position).getStatus().equals("Yes")) {
orderListViewHolder.status.setBackgroundColor(0x00ff00);
} else {
orderListViewHolder.status.setBackgroundColor(0xff0000); }
of course you must create the getStatus() method like all the others getSomething()

Assuming, that your ImageView is your indicator bar:
<ImageView
android:id="#+id/ivIndicator" <!-- Add this id -->
android:layout_marginLeft="22dp"
android:layout_marginTop="14dp"
android:layout_marginBottom="14dp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/rectangle"/>
Get a reference to it in your OrderListViewHolder:
ivIndicator = (ImageView) itemView.findViewById(R.id.ivIndicator);
And then tint your imageview in onBindViewHolder:
if("Yes".equals(itemOrderList.get(position).getStatus())) {
orderListViewHolder.ivIndicator.setColorFilter(ContextCompat.getColor(activity, android.R.color.green))
else {
orderListViewHolder.ivIndicator.setColorFilter(ContextCompat.getColor(activity, android.R.color.red))
}

Make two drawable files like #drawable/rectangle, set it with different color you want.
if(status.equals("No") {
yourView.setBackground(context.getResources().getDrawable(R.drawable.rectangleWithRed));
}
else if (status.equals("Yes") {
yourView.setBackground(context.getResources().getDrawable(R.drawable.rectangleWithGreen);
}

if you want to change the color according to the status, then on onBindViewHolder of your Recycler Adapter, check for the status and set to desired color.
if(status.equals("Yes")
{
rectangleImageView.setColor(Color.GREEN);
}
else
{
rectangleImageView.setColor(Color.RED);
}

public void onBindViewHolder(OrderListViewHolder orderListViewHolder, int position) {
if (OrderListModel.getProductStatus().equals("Yes"))
rectangleImageView.setColorFilter(getContext().getResources().getColor(R.color.green));
} else {
rectangleImageView.setColorFilter(getContext().getResources().getColor(R.color.red));
}
}

How to make Horizontal line attach textview in recyclerview?

Am having a doubt regarding how to make the horizontal view to touch the textview while populating in recyclerview , Now let me explain briefly i having a horizontal recyclerview in that adapter view holder i have horizontal view at the end of the textview which is center vertical to that textview, so when items are added each view must touch the textview like vertical dotted timeline but the view is not touching the textview as shown in the below image.
Now let me post what i have tried so far
This is the layout that holding recyclerview:
<RelativeLayout android:layout_width="wrap_content"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android" >
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/recyclerview"/>
</RelativeLayout>
Here am using that recyclerview in activity:
Recyclerview recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));
recyclerView.setHasFixedSize(true);
TrackingAdapter mAdapter = new TrackingAdapter(this.taskLogModelList,mTaskModel.getTaskID(),fm,String.valueOf(mLastLocation.getLatitude()),String.valueOf(mLastLocation.getLongitude()));
recyclerView.setAdapter(mAdapter);
mAdapter.notifyDataSetChanged();
Here is the adapter am using :
public class TrackingAdapter extends RecyclerView.Adapter<TrackingAdapter.ViewHolder> {
private List<TaskLogModel> taskStatusFlowModels;
private D2DKnocks appclass;
private String Lat,Long;
private FragmentManager fragmentManager;
private String TaskID;
DateFormat date,msimpleDateformat;
public TrackingAdapter(List<TaskLogModel> taskStatusFlowModels,String TaskID,FragmentManager context,String Lat,String Long) {
this.taskStatusFlowModels = taskStatusFlowModels;
this.fragmentManager=context;
date=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
msimpleDateformat = new SimpleDateFormat("hh.mm a");
this.Lat=Lat;
this.TaskID=TaskID;
this.Long=Long;
appclass=((D2DKnocks)D2DKnocks.getContext());
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
private AvertaTextview txt_time;
private Rubik txt_delivered;
// private AvertaButton btn_start;
private RelativeLayout layout;
private View view_right;
public ViewHolder(View itemView) {
super(itemView);
txt_time = itemView.findViewById(R.id.txt_time);
// btn_start=itemView.findViewById(R.id.start);
layout=itemView.findViewById(R.id.layout);
txt_delivered = itemView.findViewById(R.id.txt_delivered);
view_right = (View) itemView.findViewById(R.id.right_view_line);
layout.setOnClickListener(this);
}
#Override
public void onClick(View view) {
TaskLogModel taskLogModel=taskStatusFlowModels.get(getAdapterPosition());
if(taskLogModel.getTaskStatusID()==0){
TaskStatusDialog taskStatusDialog=new TaskStatusDialog();
Bundle bundle=new Bundle();
bundle.putInt("Size",taskStatusFlowModels.size());
bundle.putString("Lat",Lat);
bundle.putString("Long",Long);
bundle.putString("TaskID",TaskID);
taskStatusDialog.setArguments(bundle);
taskStatusDialog.show(fragmentManager,"show");
}
}
}
#Override
public TrackingAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_view_assignment_status, parent, false);
return new ViewHolder(itemView);
}
#Override
public void onBindViewHolder(TrackingAdapter.ViewHolder holder, int position) {
if (taskStatusFlowModels.get(position).getTaskStatusID() > 0) {
StatusModel statusFlowModel = getStatusName(taskStatusFlowModels.get(position).getTaskStatusID());
holder.txt_delivered.setText(statusFlowModel.getStatus());
holder.txt_delivered.setBackgroundResource(R.drawable.btn_arrived_bg);
try {
Date uppdateDate=date.parse(taskStatusFlowModels.get(position).getUpdateDateTime());
String updatedDate=msimpleDateformat.format(uppdateDate);
String[] each = updatedDate.split(" ");
String str = each[1].replace("AM", "am").replace("PM","pm");
// SpannableString ss1= new SpannableString(each[0]);
// SpannableString ss2=new SpannableString(each[1]);
// ss1.setSpan(new AbsoluteSizeSpan(20), 0, each[0].length(), SPAN_INCLUSIVE_INCLUSIVE);
// ss2.setSpan(new AbsoluteSizeSpan(15), 0, each[1].length(), SPAN_INCLUSIVE_INCLUSIVE);
// CharSequence finalText = TextUtils.concat(ss1, " ", ss2);
holder.txt_time.setText(each[0]+" "+str);
} catch (ParseException e) {
e.printStackTrace();
}
GradientDrawable gradientDrawable = (GradientDrawable) holder.txt_delivered.getBackground();
gradientDrawable.setColor(Color.parseColor(statusFlowModel.getStatusColor()));
} else {
holder.txt_delivered.setText("Choose");
holder.txt_delivered.setBackgroundResource(R.drawable.btn_choose_bg);
holder.txt_delivered.setTextColor(Color.parseColor("#b1b1b1"));
}
if(taskStatusFlowModels.size()-1==position){
holder.view_right.setVisibility(View.GONE);
}
else {
holder.view_right.setVisibility(View.VISIBLE);
}
}
public StatusModel getStatusName(Integer statusID){
for (int i=0;i<appclass.getStatusModelist().size();i++){
if (appclass.getStatusModelist().get(i).getStatusID().equals(statusID)){
return appclass.getStatusModelist().get(i);
}
}
return null;
}
#Override
public int getItemCount() {
return taskStatusFlowModels.size();
}
}
And below is the view holder layout:
<?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"
android:layout_marginTop="10dp"

<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/layout">

android:layout_width="wrap_content"
android:layout_height="wrap_content"

<View

android:layout_width="30dp"
android:layout_height="20dp"
android:layout_centerHorizontal="true"
android:layout_below="#+id/txt_time"

android:layerType="software"
android:visibility="visible" />
<RelativeLayout
android:layout_width="wrap_content"
android:layout_below="#+id/vertical_line"
android:layout_height="wrap_content">
<com.trident.Hawkersky.service.CustomFonts.Rubik
android:id="#+id/txt_delivered"
android:layout_centerHorizontal="true"
android:layout_width="wrap_content"
android:layout_height="#dimen/thirty"
android:layout_marginBottom="5dp"
android:singleLine="true"
android:padding="#dimen/seven"
android:background="#drawable/btn_delivered_bg"
android:gravity="center"
android:text="Delivered"
android:textAllCaps="true"
android:textColor="#FFF"
android:textSize="13sp"
android:textStyle="bold" />
<View
android:id="#+id/right_view_line" <--- this is the view
android:layout_width="#dimen/hundred"
android:layout_height="5dp"
android:layout_alignBottom="#+id/txt_delivered"
android:layout_gravity="center_vertical"
android:layout_marginBottom="12dp"
android:layout_toEndOf="#+id/txt_delivered"
android:layout_toRightOf="#+id/txt_delivered"
android:background="#drawable/dotted"
android:layerType="software"
android:visibility="visible" />
</RelativeLayout>
</RelativeLayout>
</RelativeLayout>
Now what i need is i need that view to attach to the textview , but am getting like image above how to solve it.
