Your activity is recreated on rotation.
The fragment manager stores the original fragment in the instance state, but I assume you are adding a new fragment in the onCreate() of the activity.
So you have the restored and the new fragment on top of each other.
Perhaps only add a new fragment if savedInstanceState is null.

How to fetch data related to a clicked item in a recyclerView from room database to a new activity?

My app has a RawMaterialFragment that displays raw materials data in a recyclerView from room database.
I am trying to build a detail activity(MetrialItemView) to show up the details of an individual raw material by clicking or selecting the raw material from the recyclerView.
my problem is how to send the data from the adapter and how to receive the data in the MetrialItemView Activity and display it.
MaterialListAdapter:
public class MaterialListAdapter extends RecyclerView.Adapter<MaterialListAdapter.ViewHolder> {
private final LayoutInflater mInflater;
private FragmentRawMaterials mContext;
private List<RawMaterialsEntity> mMaterial; // Cached copy of Materials
RawMaterialsEntity mCurrent;
public MaterialListAdapter(FragmentRawMaterials context) {
mInflater = LayoutInflater.from(context.getActivity());
mContext = context;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = mInflater.inflate(R.layout.list_item, parent, false);
return new ViewHolder(itemView);
}
public class ViewHolder extends RecyclerView.ViewHolder {
private final TextView materialName;
private final TextView materialBrand;
private final TextView materialQuantity;
LinearLayout parentLayout;
private ViewHolder(View itemView) {
super(itemView);
materialName = itemView.findViewById(R.id.raw_material_name);
materialBrand = itemView.findViewById(R.id.raw_material_brand);
materialQuantity = itemView.findViewById(R.id.raw_material_quantity);
parentLayout = itemView.findViewById(R.id.parent_layout);
}
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
if (mMaterial != null) {
mCurrent = mMaterial.get(position);
holder.materialName.setText(mCurrent.getRawMaterialName());
holder.materialBrand.setText(mCurrent.getRawMaterialBrand());
holder.materialQuantity.setText(String.valueOf(mCurrent.getRawMaterialQuantity()));
} else {
// Covers the case of data not being ready yet.
holder.materialName.setText("Name NA");
holder.materialBrand.setText("Brand NA");
holder.materialQuantity.setText("Quantity NA");
}
holder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(mContext.getContext(), MaterialItemView.class);
mContext.startActivity(intent);
}
});
}
public void setMaterial(List<RawMaterialsEntity> materials){
mMaterial = materials;
notifyDataSetChanged();
}
// getItemCount() is called many times, and when it is first called,
// mWords has not been updated (means initially, it's null, and we can't return null).
#Override
public int getItemCount() {
if (mMaterial != null)
return mMaterial.size();
else return 0;
}
}
MaterialItemView:
public class MaterialItemView extends AppCompatActivity {
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.material_item_view);
}

each row of dataModel() must have ID and then use putExtra() whan clicked It happens
holder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(mContext.getContext(), MaterialItemView.class);
intent.putExtra("ID",mCurrent.getID());

}
});
and use getIntent() in detailActivity
int id =getIntent().getIntExtra("ID",-1);
and then get a row data in detail activity from database(viewModel)by ID and parse it

i tried a lot to make all of the layouts match parent and it still as it appears above and i search about the problem i saw this
it gives it specific width

In your ReviewsRvAdapter class, inside the onCreateViewHolder() method, you have this line of code:
View layoutView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.list_item_user_review, null);
Right now, you're passing null as the parent when inflating the view. This makes it impossible for the created view to "match parent" for the width.
Change that to this instead:
View layoutView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.list_item_user_review, parent, false);
Now you will have a non-null parent when you inflate the view, and so the width will be set correctly.

Android viewpager with recyclerview not working in fragment

I am working with recyclerview with viewpager in fragment.
I want to make navigation on bottom of screen.
enter image description here
and when I click each button, each fragment show in the frameLayout.
the problem is happen when I enter into the artist fragment second time.(at first time it show up find as I intended.)
as you can see in this image enter image description here

It's hard to tell exactly due to the navigational structure of your app, but think the solution to your problem is to use the childFragmentManager inside of the ArtistBoardFragment. i.e, instead of
pageAdapter = new FragmentPagerAdapter(getActivity().getSupportFragmentManager()) ...
Use
pageAdapter = new FragmentPagerAdapter(getChildFragmentManager()) ...

CardView not displaying within RecyclerView

Before you ask, yes I know there are many questions that are very similar to this and I have tried most of them to no avail. My problem is that a CardView is not displaying within a RecyclerView. The items whithin it are displaying but not the card itself.
Without further or do, here's my code:
Adapter:
Integer count = 0;
Boolean isStart = true;
String datag = "";
String typeg = "";
Integer LastItemType=0; //0=None 1=Text 2=Image
ViewHolder a;
#Override
public EntryAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
a= createholder(parent, viewType);
return(a);
}
public ViewHolder createholder(ViewGroup parent, int viewtype) {
if (typeg.equals("image")) {
View root = LayoutInflater.from(parent.getContext())
.inflate(R.layout.listitems, parent, false);
CardView card = (CardView) root.findViewById(R.id.card_view);
ImageView image = (ImageView) root.findViewById(R.id.Img);
((ViewGroup)image.getParent()).removeView(root.findViewById(R.id.card_view));
if (LastItemType == 2) {
((ViewGroup)image.getParent()).removeView(root.findViewById(R.id.Img));
}
if (LastItemType == 1) {
((ViewGroup)image.getParent()).removeView(root.findViewById(R.id.Txt));
}
ViewHolder vh = new ViewHolder(image, card);
LastItemType = 2;
return vh;
} else {
if (typeg.equals("text")) {
View root = LayoutInflater.from(parent.getContext())
.inflate(R.layout.listitems, parent, false);
CardView card = (CardView) root.findViewById(R.id.card_view);
TextView image = (TextView) root.findViewById(R.id.Txt);
((ViewGroup)image.getParent()).removeView(root.findViewById(R.id.card_view));
if (LastItemType == 1) {
((ViewGroup)image.getParent()).removeView(root.findViewById(R.id.Txt));
}
if (LastItemType == 2) {
((ViewGroup)image.getParent()).removeView(root.findViewById(R.id.Img));
}
ViewHolder vh = new ViewHolder(image, card);
LastItemType = 1;
return vh;
}
return null; //TODO: REMOVE!
}
}
#Override
public void onBindViewHolder(EntryAdapter.ViewHolder holder, int position) {
// Deal with data
}
public class ViewHolder extends RecyclerView.ViewHolder {
public ImageView imgg;
public TextView txtg;
public CardView cardg;
public ViewHolder(ImageView image, CardView card) {
super(image);
imgg = image;
cardg = card;
}
public ViewHolder(TextView text, CardView card) {
super(text);
txtg = text;
cardg = card;
}
}
#Override
public int getItemCount() {
return count;
}
public void refresh(String data, String type, ViewGroup parent) {
isStart = false;
datag = data;
typeg = type;
count++;
createholder(parent, -100);
}

Thanks in advance!

Check out my code, i use it for each of my app after modifying it slightly. You can also use adapter if you have more than one RecyclerViews by changing it's type field and layout and views accordingly. It contains a CoordinatorLayout that has CollapsingLayout with ImageView in it. It contains many layouts for Material Design, i hope it helps.
Activity contains RecyclerView and CardView, i removed things like database, Floating action buttons that you may not need and may make it more difficult to understand. If you need the whole class contact me.

How it looks

Does your RecyclerView show ImageView or TextView only?
If yes, because your ViewHolder Constructor is wrong. You have to call super(itemView) in your ViewHolder's Constructor, itemView is the view which is displayed as a row in RecyclerView. To fix your issue, I think you should change your code as below:
public ViewHolder createholder(ViewGroup parent, int viewtype) {
if (typeg.equals("image") || typeg.equals("text")) {
View root = LayoutInflater.from(parent.getContext())
.inflate(R.layout.listitems, parent, false);
return new ViewHolder(root, typeg.equals("text"));
}
//FIXME: As my expericence you should NOT return null for ViewHolder. You have to sure the typeg is one of "image" or "text". I think you should change typeg to Boolean variable to not return null ViewHolder.
return null;
}
public class ViewHolder extends RecyclerView.ViewHolder {
public ImageView imgg;
public TextView txtg;
public CardView cardg;
public ViewHolder(View itemView, boolean isTypeText) {
super(itemView);
imgg = (ImageView) itemView.findViewById(R.id.Img);
cardg = (CardView) itemView.findViewById(R.id.card_view);
txtg = (TextView) itemView.findViewById(R.id.Txt);
imgg.setVisibility(isTypeText ? View.GONE : View.VISIBLE);
txtg.setVisibility(isTypeText ? View.VISIBLE : View.GONE);
}
}

Here is the proper Documentation Read and And Follow it.
You must be Doing Something Wrong in Gradle.!
so, the issue was Your XML was not showing CardView in it here we go.!
Add following Dependencies.!
compile 'com.android.support:design:25.3.1'
compile 'com.android.support:support-v4:25.3.1'
compile 'com.android.support:cardview-v7:25.3.1'
compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.android.support:appcompat-v7:25.3.1'
testCompile 'junit:junit:4.12'
Here is Your XML is Working Perfectly Fine.!

Is it because you are removing card_view like so?

Android: Multi Pane layout detail view appears by default

In my app, I have requirement of Multi Payne layout. In this layout, the first fragment is a ListView which shows the list of items. On click of the list item, a detail view will open up on the right hand side of the list item. But, in my case, when I run my app on tablet, the detail view appears along with ListView by default. While, I want that it should appear on click of the list item.
Below is my code:
Activity Class:
public class OrderActivity extends FragmentActivity implements
OnOrderSelectedListener {
private static final String TAG = "OrderActivity";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d(TAG, "onCreate called");
setContentView(R.layout.order_details);
if (findViewById(R.id.fragment_container) != null) {
if (savedInstanceState != null) {
return;
}
OrderListFragment orderListFragment = new OrderListFragment();
orderListFragment.setArguments(getIntent().getExtras());
getSupportFragmentManager().beginTransaction()
.add(R.id.fragment_container, orderListFragment).commit();
}
}
#Override
public void onOrderSelected(int position) {
Log.d(TAG, "onOrderSelected called");
OrderDetailFragment detailsFrag = (OrderDetailFragment) getSupportFragmentManager()
.findFragmentById(R.id.order_detail_fragment);
if (detailsFrag != null) {
if (!detailsFrag.isVisible()) {
detailsFrag.setUserVisibleHint(true);
detailsFrag.updateOrderView(position);
}
} else {
OrderDetailFragment newFragment = new OrderDetailFragment();
Bundle args = new Bundle();
args.putInt(OrderDetailFragment.ARG_POSITION, position);
newFragment.setArguments(args);;
FragmentTransaction transaction = getSupportFragmentManager()
.beginTransaction();
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);
transaction.commit();
}
}
}
LIst Fragment
public class OrderListFragment extends ListFragment {
private static final String TAG = "OrderListFragment";
OnOrderSelectedListener mOnOrderSelectedListener;
public interface OnOrderSelectedListener {
public void onOrderSelected(int position);
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d(TAG, "onCreate called");
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Log.d(TAG, "onCreateView called");
return inflater.inflate(R.layout.order_list, null);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
Log.d(TAG, "onActivityCreated called");
ArrayList<Data> mDataList = new ArrayList<Data>();
Data mData1 = new Data("1", "11001", "08/07/2013", "GAUGE_RUN",
"Dispatched", "Terminal:", "Rail Terminal:", "New York",
"Washington DC");
Data mData2 = new Data("1", "11002", "08/07/2013", "GAUGE_RUN",
"Dispatched", "Terminal:", "Rail Terminal:", "New York",
"Washington DC");
mDataList.add(mData1);
mDataList.add(mData2);
setListAdapter(new OrderAdapter(getActivity(),
R.layout.order_list_item, mDataList));
}
#Override
public void onStart() {
super.onStart();
Log.d(TAG, "onStart called");
if (getFragmentManager().findFragmentById(R.id.order_detail_fragment) != null) {
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
}
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
Log.d(TAG, "onAttach called");
// This makes sure that the container activity has implemented
// the callback interface. If not, it throws an exception.
try {
mOnOrderSelectedListener = (OnOrderSelectedListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement OnHeadlineSelectedListener");
}
}
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
Log.d(TAG, "onListItemClicked");
mOnOrderSelectedListener.onOrderSelected(position);
getListView().setItemChecked(position, true);
}
}
Detail Fragment
public class OrderDetailFragment extends Fragment {
public final static String ARG_POSITION = "position";
int mCurrentPosition = -1;
private static final String TAG = "OrderDetailFragment";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Log.d(TAG, "onCreateView called");
if (savedInstanceState != null) {
mCurrentPosition = savedInstanceState.getInt(ARG_POSITION);
}
return inflater.inflate(R.layout.acceptance_details, container, false);
}
#Override
public void onStart() {
Log.d(TAG, "onStart called");
super.onStart();
Bundle args = getArguments();
if (args != null) {
updateOrderView(args.getInt(ARG_POSITION));
} else if (mCurrentPosition != -1) {
updateOrderView(mCurrentPosition);
}
}
public void updateOrderView(int position) {
Log.d(TAG, "updateOrderView called");
/*
* TextView article = (TextView)
* getActivity().findViewById(R.id.article);
* article.setText(Ipsum.Articles[position]); btnNext = (Button)
* getActivity().findViewById(R.id.btnNext);
* btnNext.setOnClickListener(this); mCurrentPosition = position;
*/
}
#Override
public void onSaveInstanceState(Bundle outState) {
Log.d(TAG, "onSaveInstanceState called");
super.onSaveInstanceState(outState);
outState.putInt(ARG_POSITION, mCurrentPosition);
}
}

I did gone through Fragments Basic Demo given on the Android developer's site, but couldn't figure out my mistake.

try this
listview.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
listview.setItemChecked(0,false);
