Someone please let me know how can I get and add total cost from each row and show it in lower left area. Any help would be appreciated.
THANKS

You can use array and append the value of each cell in it and never clear it, then create a function in your adapter that return with this array, here you cal add it's items.

my error like this
why my imageview working but textview not working
thank you for attention

mOnItemClickListener.onItemClick(view, checkList.get(getAdapterPosition()), getAdapterPosition(), list.get(getAdapterPosition()));
change to
mOnItemClickListener.onItemClick(v, checkList.get(getAdapterPosition()), getAdapterPosition(), list.get(getAdapterPosition()));

This is because the id tvKonten does not exist. In your XML code, the id of the TextView is txtsuka, not tvKonten. Change tvKonten to txtsuka.

Try these options, it might work for you :
Invalidate Caches and Restart
Check if you have a different version of the same layout file in your res folder such as ...v26.xml or something like that ; if you find any then delete the unwanted version of the file.

How can i Add the click listeners to the child of Recycler View?

Here is my discussion.java which contains the RecyclerView
public class Discussion extends AppCompatActivity {

getSupportActionBar().setDisplayHomeAsUpEnabled(true);

String[] use ={"a","b"};
String[] lo={"be","ndls"};
String[] ti={"12:00","11:00"};
String[] staus={"Today","Tommmorow"};
int[] posimg={R.drawable.img_post1,R.drawable.img_post2};
mRecycleview.setAdapter(new FeedAdapter(use,lo,ti,staus,posimg));
#NonNull
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new OnClickListener() {

// Functionality for poll

Here is my content.xml from which adapter is taking the feed. I want to set up the onClickListner on the view id:likelayout" or like so that when it is clicked, some actions are to be performed. For now, a toast would be enough.
Please help me out how to do it.

In your onBindViewHolder function, just add a click listener like the following.
#Override
public void onBindViewHolder( FeedAdapter.FeedViewHolder holder, int position) {
String user=userdata[position];
String loc=locdata[position];
String time=timedata[position];
String status=statusdata[position];
int post=postdata[position];
holder.username.setText(user);
holder.locationa.setText(loc);
holder.timea.setText(time);
holder.statusa.setText(status);
if(post==0)
holder.postimg.setVisibility(View.GONE);
else
holder.postimg.setImageResource(post);
holder.username.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
// Do something.
}
});
}
If you want to set up the click listener to the other UI elements in your list item, then just declare them like the way you have declared username, timea, statusa etc. and then add the listener to it.
Please keep in mind that, in order to make an ImageView clickable you need to add the clickable attribute to true in your layout file. For example, if you need to make your like image clickable, you need to add the clickable attribute like the following.
<ImageView
android:id="#+id/like_image"
android:layout_width="25dp"
android:layout_height="wrap_content"
android:clickable="true"
android:src="#drawable/like"/>
In order to show a Toast on clicking the item, you need to have the Context of the Discussion activity while you are creating the adapter. So I would like to suggest you modify the constructor of the adapter like the following.
public class FeedAdapter extends
RecyclerView.Adapter<FeedAdapter.FeedViewHolder> {
private String[] userdata;
private String[] locdata;
private String[] timedata;
private int[] postdata;
private String[] statusdata;
// Add another extra variable to store context
// The context is necessary for showing toast
private Context context;
public FeedAdapter(String[] userdata, String[] locdata,String[] timedata, String[] statusdata, int[] postdata, Context context){
this.userdata = userdata;
this.locdata = locdata;
this.postdata = postdata;
this.statusdata = statusdata;
this.timedata = timedata;
this.context = context; // Initialize it here
}
#Override
public FeedViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater=LayoutInflater.from(parent.getContext());
View view =inflater.inflate(R.layout.backupofcontent,parent,false);
return new FeedViewHolder(view);
}
#Override
public void onBindViewHolder( FeedAdapter.FeedViewHolder holder, int position) {
String user=userdata[position];
String loc=locdata[position];
String time=timedata[position];
String status=statusdata[position];
int post=postdata[position];
holder.username.setText(user);
holder.locationa.setText(loc);
holder.timea.setText(time);
holder.statusa.setText(status);
if(post==0)
holder.postimg.setVisibility(View.GONE);
else
holder.postimg.setImageResource(post);
// Use the context here to show the Toast
holder.username.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context, "Something", Toast.LENGTH_LOGN).show();
}
});
}
#Override
public int getItemCount() {
return userdata.length;
}
public class FeedViewHolder extends RecyclerView.ViewHolder{
ImageView postimg;
TextView username;
TextView locationa;
TextView timea;
TextView statusa;
public FeedViewHolder(View itemView) {
super(itemView);
postimg=itemView.findViewById(R.id.imgView_postPic);
username=itemView.findViewById(R.id.user_name);
locationa=itemView.findViewById(R.id.Location);
timea=itemView.findViewById(R.id.Time);
statusa=itemView.findViewById(R.id.post_text);
}
}
}
And to adopt the changes of the modified constructor, the adapter needs to be initialized like the following from your Discussion class.
mRecycleview.setAdapter(new FeedAdapter(use, lo, ti, staus, posimg, this));
Hope that helps!

same as the other views, in the FeedViewHolder class add a LinearLayout variable:
LinearLayout like;
then
like = itemView.findViewById(R.id.likelayout);
then in onBindViewHolder use :
holder.like.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
// Like Layout was clicked
}
});

How to call a map fragment from another class

Android List View shows items, but text is empty

I am experiencing a very weird issue where I am unable to view any text/data, but it clearly shows the number of items in the list.
I have confirmed that dataList has data, and I am able to get the exact same string that I set after debugging.

EDIT: Screenshot added
EDIT2: Clarified parent fragment calling the adapter.
EDIT3: I did a temporary fix. Apparently the RelativeLayout and the Linear Layout in the AdapterXML were the cause of my misery. I'm not exactly sure why, though. I think it's the RelativeLayout and the LinearLayout somehow not displaying the text. Removing those two tags will display the texts in a linear fashion.

Try this
Adapter XML:

Title in the BottomSheet

I have a BottomSheet with a RecyclerView, and I want to add a title there as in the picture below ("Add new record"), I was trying to add TextView before the RecyclerView in the bottom_sheet LinearLayout, but this text doesn't appear on the screen, also I was trying to add an item in the RecyclerView (but I have a feeling that it's not a right approach), so my question is how to add the title to the BottomSheet?
This is the method where I'm adding items to the RecyclerView, which is in the BottomSheet:
private void showBottomSheetDialog() {
if (behavior.getState() == BottomSheetBehavior.STATE_EXPANDED) {
behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
}
mBottomSheetDialog = new BottomSheetDialog(this);
View view = getLayoutInflater().inflate(R.layout.sheet, null);
RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(new ItemAdapter(createItems(), new ItemAdapter.ItemListener() {
#Override
public void onItemClick(Item item) {
if (mBottomSheetDialog != null) {
mBottomSheetDialog.dismiss();
}
}
}));
mBottomSheetDialog.setContentView(view);
mBottomSheetDialog.show();
mBottomSheetDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
mBottomSheetDialog = null;
}
});
}
#Override
protected void onDestroy() {
super.onDestroy();
mAdapterItem.setListener(null);
}
public List<Item> createItems() {
ArrayList<Item> items = new ArrayList<>();
items.add(new Item(R.drawable.camera, "from new shoots"));
items.add(new Item(R.drawable.folder_multiple_image, "from ready images"));
return items;
}
xml of the screen:
