I have a RecyclerView inside BottomSheetDialogFragment. The RecyclerView items touch working normally when it's scrolling slowly.
But when the RecyclerView is scrolled fast and after the list stops (without touching), than touching on any item doesn't work on fast touch. It needs double touching.
See in the below example gif, when touching on Andhra Pradesh it's working fine. After slow scrolling, touching on Haryana also works fine. Then doing a fast scroll and touching on Punjab doesn't work on the first touch. Touching again it works.
Following is the code:
OperatorListDialogFragment.java
package com.*;
import *;
public class OperatorListDialogFragment extends BottomSheetDialogFragment{
private static final String ARG_NAME = "item_name";
private static final String ARG_LOGO = "item_logo";
private Listener mListener;
private String header;
private Context mContext;
public static OperatorListDialogFragment newInstance(String[] name, int[] logo, String header) {
final OperatorListDialogFragment fragment = new OperatorListDialogFragment();
final Bundle args = new Bundle();
args.putStringArray(ARG_NAME, name);
args.putIntArray(ARG_LOGO, logo);
args.putString("header", header);
fragment.setArguments(args);
return fragment;
}

I use navigationview. I want to use two icons in navigation view. Currently, when I use .seticon, it changes 2 icons. I want to define icons in two icons separately. I want to define separate icons for navIconNew and navIcon. How can we do that?

I'm cant get the onclicklistener to work with fragments. I've searched stackoverflow and tried all the tips but i still cant get it to work. So i do my first post here. I've tried adding android:focusable="false", android:clickable="false" and android:descendantFocusability="blocksDescendants" to the layouts with no luck. Ive removed them because they make no difference. I've tried other solutions as well but none of them works. This is my first post so if i posted something wrong let me know and ill redo it, I've borrowed someones customlist just to get a working example.
Here is one of the fragments i want a clickable list in
public class ActivitiesFragment extends Fragment {
ListView list;
String[] maintitle ={
"Aktivitet 1","Aktivitet 2",
"Aktivitet 3","Aktivitet 4",
"Aktivitet 5",
};
String[] subtitle ={
"A","B",
"C","D",
"E",
};
Integer[] imgid={
R.drawable.ic_dashboard_black_24dp,R.drawable.ic_dashboard_black_24dp,
R.drawable.ic_dashboard_black_24dp,R.drawable.ic_dashboard_black_24dp,
R.drawable.ic_dashboard_black_24dp,
};
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_activities, container, false);
MyListAdapter adapter = new MyListAdapter(getActivity(), maintitle, subtitle,imgid);
list = (ListView) rootView.findViewById(R.id.list);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if(position == 0) {
Toast.makeText(getActivity().getApplicationContext(),"One",Toast.LENGTH_SHORT).show();
}
else if(position == 1) {
Toast.makeText(getActivity().getApplicationContext(),"Two",Toast.LENGTH_SHORT).show();
}
else if(position == 2) {
Toast.makeText(getActivity().getApplicationContext(),"Three",Toast.LENGTH_SHORT).show();
}
else if(position == 3) {
Toast.makeText(getActivity().getApplicationContext(),"Four",Toast.LENGTH_SHORT).show();
}
else if(position == 4) {
Toast.makeText(getActivity().getApplicationContext(),"Five",Toast.LENGTH_SHORT).show();
}
}
});
return rootView;
}
}
Here is the Adapter:
public class MyListAdapter extends ArrayAdapter<String> {
private final Activity context;
private final String[] maintitle;
private final String[] subtitle;
private final Integer[] imgid;
public MyListAdapter(Activity context, String[] maintitle,String[] subtitle, Integer[] imgid) {
super(context, R.layout.mylist, maintitle);
// TODO Auto-generated constructor stub
this.context=context;
this.maintitle=maintitle;
this.subtitle=subtitle;
this.imgid=imgid;
}
public View getView(int position,View rowView,ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
rowView = inflater.inflate(R.layout.mylist, null,true);
TextView titleText = (TextView) rowView.findViewById(R.id.title);
ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
TextView subtitleText = (TextView) rowView.findViewById(R.id.subtitle);
titleText.setText(maintitle[position]);
imageView.setImageResource(imgid[position]);
subtitleText.setText(subtitle[position]);
return rowView;
}
}
The xml for the fragment:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/list"

RVAdapter adapter = new RVAdapter(this, list);
rvList.setLayoutManager(new LinearLayoutManager(getContext()));
rvList.setAdapter(adapter);
}
#Override

Update 1:
Add these lines to the root tag of item layout:
android:focusable="true"
android:clickable="true"
Like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusable="true"
android:clickable="true"
android:orientation="horizontal">
...
</LinearLayout>
Time ago I had a similar problem, with an ImageView in my list item. My solution was changing android:focusable to false inside the ImageView block. I never knew why, but it worked fine.
Anyway, I strongly recommend to start using RecyclerView and ViewHolder pattern. https://developer.android.com/guide/topics/ui/layout/recyclerview
It's much more powerful, flexible and a major enhancement over ListView.
I have passed the parent to onCreateViewHolder instead of null but it is not showing match parent.
Please tell me if there is any error in the code?
Here is my Main_Adapter.class:
public class Main_Adapter extends RecyclerView.Adapter<Main_Adapter.ViewHolder> {
private List<MainModel> mainModels;
private Context context;
private OnClicklisteners listener;
public Main_Adapter(List<MainModel> mainModels, Context context, OnClicklisteners onClicklisteners) {
this.mainModels = mainModels;
this.context = context;
this.listener=onClicklisteners;
}
public interface OnClicklisteners{
public void onPosClicked(View view, int pos, ImageView mainimage, ArrayList<Integer> colorlist);
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.main_card, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(final ViewHolder holder, int position) {
holder.main_text.setText(mainModels.get(position).getName());
Picasso.with(context).load(mainModels.get(position).getImageName()).fit().centerInside().into(holder.mainimage);
}
#Override
public int getItemCount() {
return mainModels.size();
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
#BindView(R.id.main_image)
ImageView mainimage;
#BindView(R.id.main_text)
TextView main_text;
Typeface ubuntu;
int colors;
ArrayList<Integer> colorlist =new ArrayList<>();
public ViewHolder(View itemView) {
super(itemView);
ButterKnife.bind(this, itemView);
itemView.setOnClickListener(this);
}
#Override
public void onClick(View view) {
int pos = getAdapterPosition();
listener.onPosClicked(view,pos,mainimage,colorlist);
}
}
Here is main_card.xml:

It should show full width but it's showing only a wrap content. I have found a similar post but they are telling to pass parent in onCreateViewHolder. I have done that but it didn't help me.

I am using vector images generated from Android Studio but those images are not displayed in recyclerView.
What should i do? Let me mention that the vector images that i use inside recyclerView are properly displayed if i use them in simple image views.
