i'm having problem with Videoview. i have done all the settings right but still it dosen't show anything in Videoview. finally i used a library but the problem was'nt solved. i used the videoview inside the recyclerview like the example in github: (https://github.com/Krupen/AutoplayVideos), here is my code, and single_view is the layout for each item:
single_view:
<?xml version="1.0" encoding="utf-8"?>

</FrameLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="hello"/>
this is my main layout which contains the recyclerview:

The recyclerView Adapter:
public class MyVideosAdapter extends AAH_VideosAdapter {
private List<String> list;
public class MyViewHolder extends AAH_CustomViewHolder {
//to mute/un-mute video (optional)
boolean isMuted;
public MyViewHolder(View x) {
super(x);
}
}
public MyVideosAdapter(List<String> list_urls) {
this.list = list_urls;
}
#Override
public AAH_CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.row_videos, parent, false);
return new MyViewHolder(itemView);
}
#Override
public void onBindViewHolder(AAH_CustomViewHolder holder, int position) {
holder.setVideoUrl(list.get(position));
}
#Override
public int getItemCount() {
return list.size();
}
#Override
public int getItemViewType(int position) {
return 0;
}
}
finally i set the recyclerview in my fragment as folloe:
LinearLayoutManager linearLayoutManager2 = new LinearLayoutManager(getContext());
linearLayoutManager2.setOrientation(LinearLayoutManager.HORIZONTAL);
recycler_storyRelatedVideos.setActivity(getActivity());
recycler_storyRelatedVideos.setLayoutManager(linearLayoutManager2);
adapter_videos = new MyVideosAdapter(story.getList_storyVideos());
recycler_storyRelatedVideos.setHasFixedSize(true);
recycler_storyRelatedVideos.setAdapter(adapter_videos);
recycler_storyRelatedVideos.smoothScrollBy(0,1);
recycler_storyRelatedVideos.smoothScrollBy(0,-1);

The recycler view with cardview items is showing in black. Also I cannot change background colour. But when running in android emulator it seems fine, the background is default in white color. What could i had done wrong

Try this code.
Just add a background attribute android:background="#android:color/white" to your sampcard.xml layout.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"

I encountered the same problem and got it resolved by applying Background color to the root view in XML file which in you case is Recycler view.
Add this in your Recycler View XML code :
android:background = "#ffffff"

Im using a Vertical LinearLayoutManager for Chapter_list Recyclerview and GridLayoutManager for Calendar RecyclerView

You can try this, but still problems connected to the nested scrolling and so on are actually common. People have had the same problems here on StackOverflow, take a look, i hope it can help you: Problems with Nested Scrolling

I am trying a list of items using RecyclerView , everything works fine but the last item is not being displayed! The length of the list is 2 and onBindView is called twice and the when I used Log to print the items it aslo prints the last item. So the list is fine but the RecyclerView is not displaying it.
This is my code RecyclerView Adapter:
public class ModuleList extends RecyclerView.Adapter<ModuleList.ViewHolder> {
private List<Module> moduleList;
public ModuleList(List<Module> moduleList){
this.moduleList = moduleList;
}
public ModuleList(){
this.moduleList = new ArrayList<>();
}
public List<Module> getModuleList() {
return moduleList;
}
public void setModuleList(List<Module> moduleList) {
this.moduleList = moduleList;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_modules,parent,false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
Module module = moduleList.get(position);
// function is called twice and the all items are logged works fine
Log.d("ALL",module.getModuleName());
Log.d("ALL", String.valueOf(module.getNumberOfLevels()));
holder.moduleName.setText(String.valueOf(module.getModuleName()));
holder.numberOfLevels.setText(String.valueOf(module.getNumberOfLevels()));
}
#Override
public int getItemCount() {
//size is 2
return moduleList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
public TextView moduleName;
public TextView numberOfLevels;
public ViewHolder(View itemView) {
super(itemView);
moduleName = (TextView) itemView.findViewById(R.id.list_module_name);
numberOfLevels = (TextView) itemView.findViewById(R.id.list_no_of_levels);
}
}
}

Hey can you try the solution below?
Change this in the list_module.xml
<?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="vertical">
<TextView
android:id="#+id/list_module_name"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/list_no_of_levels"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
I have replaced match_parent to wrap_content to parent layout.
I finally managed to get the card view to look just like I want it.
I use a GridLayoutManager with two columns to display cards with a thumbnail. Everything nice and working so far.
Anyway, once I scroll up, everything blows up. Large gaps (the size of a card itself) emerge between each row, now I every second row will be an empty one. I do not understand how that would possibly happen. I don't have any problem while scrolling down, but even one inch back up and everything is in pieces (so to speak).
Maybe some can see what is wrong with the layout.

Changing the layout_height to wrap_content fixed the problem.
I have 2 layouts in an app that are being covered by the toolbar. In each layout I've tried using android:layout_below="#id/app_bar_layout or android:layout_below="#id/toolbar, with no luck. How can I fix this?
The recycler view is called by a touch on an menu item and, inflated by rv adpater and view holder classes. So far, I have no other problems with the app except the toolbar covering the views.

result of adding appbar_scrolling_view_behavior as suggested. A blank bar covers the textview that has just animated itself visible.
You have to add following attribute to the parent view in content_main.xml
app:layout_behavior="#string/appbar_scrolling_view_behavior"
Like this:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.test09feb.MainActivity"
tools:showIn="#layout/app_bar_main"
xmlns:app="http://schemas.android.com/apk/res-auto"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</FrameLayout>
Your Toolbars height is defined by: android:layout_height="?attr/actionBarSize"
so I added a top margin with those values to the list view:
android:layout_marginTop="?attr/actionBarSize"
Worked for me in the app I'm working on.
