I tried to load a mapView in the listView for each item using baseAdaptor everything seems to be fine but maps(mapviews) are loading this way(the picture below is a single item of the list):
adapter class:
public class InfoAdapter extends BaseAdapter {
protected MapView mMapView;
GoogleMap googleMap;
Activity activity;
Bundle bundle;
Context context;
LayoutInflater layoutInflater;
ArrayList<Info> infos;
public TripsAdapter(Activity activity, Context context, ArrayList<Info> infos, Bundle bundle) {
this.context = context;
this.activity = activity;
this.layoutInflater = LayoutInflater.from(activity);
this.infos = infos;
this.bundle = bundle;
}
#Override
public int getCount() {
return infos.size();
}
#Override
public Object getItem(int i) {
return infos.get(i);
}
#Override
public long getItemId(int i) {
return i;
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
if (view == null) {
view = layoutInflater.inflate(R.layout.list_infos_item, viewGroup, false);
view.findViewById(R.id.btnShare).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//share it
}
});
}
mMapView = (MapView) view.findViewById(R.id.fragment_embedded_map_view_mapview);
mMapView.onCreate(bundle);
return view;
}
}
the list_infos_item.xml is :
<?xml version="1.0" encoding="utf-8"?>

I am creating a Fragment that has 5 horizontal recycler views under a vertical Scroll View but each time this fragment needs to be loaded, the UI freezes for about a second.
I have created an Adapter that sets the Data from 2 different POJOs into the different Recycler Views. I have found out that the line from my code which seems to be causing the issue is the setLayoutManager() because once commented, the fragment loading does not freeze the UI. Apart from that I haven't been able to find out why is that happening when assigning the LayoutManger to the recycler view and what could I do to improve the fragment's performance.
Here is the fragment_home.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.entertainment.logicaldays.planetmovie.views.fragments.HomeFragment"
android:id="#+id/layout"
android:background="#color/colorPrimary">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/scroll_view">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="#+id/view_pager"
android:layout_marginBottom="5dp">
</android.support.v4.view.ViewPager>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/recycler_popular_movies"
android:orientation="horizontal">
</android.support.v7.widget.RecyclerView>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/recycler_upcoming_movies"
android:orientation="horizontal">
</android.support.v7.widget.RecyclerView>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/recycler_top_rated_movies"
android:orientation="horizontal">
</android.support.v7.widget.RecyclerView>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/recycler_popular_tv_shows"
android:orientation="horizontal">
</android.support.v7.widget.RecyclerView>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/recycler_top_rated_tv_shows"
android:orientation="horizontal">
</android.support.v7.widget.RecyclerView>
</LinearLayout>
</ScrollView>
</FrameLayout>
Then I have the recycler_item.xml to bind to the Recycler Views:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="5dp">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="center">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/hover_values">
<ImageView
android:layout_width="wrap_content"
android:layout_height="150dp"
android:src="#drawable/ic_launcher_background"
android:layout_gravity="center|top"
android:id="#+id/recycler_image" />
<ImageView
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_alignParentTop="true"
android:layout_marginTop="20dp"
android:alpha="0"
android:id="#+id/poster_hover_image"
android:layout_centerHorizontal="true"
android:src="#drawable/star"/>
<TextView
android:layout_marginTop="5dp"
android:alpha="0"
android:id="#+id/poster_hover_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/poster_hover_image"
android:fontFamily="#font/theboldfont"
android:layout_centerHorizontal="true" />
</RelativeLayout>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAlignment="center"
android:scrollHorizontally="true"
android:minLines="2"
android:maxLines="2"
android:ellipsize="end"
android:id="#+id/recycler_title"/>
</LinearLayout>
</LinearLayout>
The Adapter which can bind 2 different POJOs into the Recycler Views:
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder>{
public Object pojo;
public Context context;
public RecyclerViewAdapter(Context ctx, Object movies) {
this.pojo = movies;
this.context = ctx;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_item, parent, false);
final ValueAnimator animatorPosterTint = ValueAnimator.ofInt(0, 180);
final ValueAnimator animatorHoverOpacity = ValueAnimator.ofFloat(0, 1);
//When long-pressing the Movie
view.setOnLongClickListener(new LongClickOnPosterItemListerner(view, animatorPosterTint, animatorHoverOpacity));
//When releasing the touch on the movie
view.setOnTouchListener(new ReleasePosterItemListener(view, animatorPosterTint, animatorHoverOpacity));
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
if(pojo instanceof MovieList) {
holder.title.setText(((MovieList)pojo).results.get(position).title);
Glide.with(context)
.asBitmap()
.load(Utils.BASE_TMDB_POSTER_URL + ((MovieList)pojo).results.get(position).posterPath)
.into(holder.image);
holder.rating.setText(Float.toString(((MovieList)pojo).results.get(position).voteAverage));
}
else{
holder.title.setText(((TVList)pojo).results.get(position).name);
Glide.with(context)
.asBitmap()
.load(Utils.BASE_TMDB_POSTER_URL + ((TVList)pojo).results.get(position).posterPath)
.into(holder.image);
holder.rating.setText(Float.toString(((TVList)pojo).results.get(position).voteAverage));
}
}
#Override
public int getItemCount() {
int count = 0;
if(pojo instanceof MovieList && ((MovieList)pojo).results != null) {
if (((MovieList)pojo).results != null) {
count = ((MovieList)pojo).results.size();
}
}
else{
if (((TVList)pojo).results != null) {
count = ((TVList)pojo).results.size();
}
}
return count;
}
public class ViewHolder extends RecyclerView.ViewHolder{
ImageView image;
TextView title;
TextView rating;
public ViewHolder(View itemView) {
super(itemView);
image = itemView.findViewById(R.id.recycler_image);
title = itemView.findViewById(R.id.recycler_title);
rating = itemView.findViewById(R.id.poster_hover_text);
}
}
}
And finally we have the HomeFragment.java
public class HomeFragment extends Fragment {
public MainActivity mainActivity;
#BindView(R.id.recycler_popular_movies)
RecyclerView recyclerPopularMovies;
#BindView(R.id.recycler_upcoming_movies)
RecyclerView recyclerUpcomingMovies;
#BindView(R.id.recycler_top_rated_movies)
RecyclerView recyclerTopRatedMovies;
#BindView(R.id.recycler_popular_tv_shows)
RecyclerView recyclerPopularTVShows;
#BindView(R.id.recycler_top_rated_tv_shows)
RecyclerView recyclerTopRatedTVShows;
#BindView(R.id.view_pager)
ViewPager viewPager;
LinkedHashMap<Utils.RequestsToLoad, Boolean> requestsToLoad;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mainActivity = (MainActivity) getActivity();
// Inflate the layout into the Fragment
View v = inflater.inflate(R.layout.fragment_home, container, false);
ButterKnife.bind(this, v);
startViewPager();
startRecyclerViews();
return v;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
private void startRecyclerViews(){
displayRecyclerView(recyclerPopularMovies, mainActivity.popularMovies);
displayRecyclerView(recyclerTopRatedMovies, mainActivity.upcomingMovies);
displayRecyclerView(recyclerUpcomingMovies, mainActivity.topRatedMovies);
displayRecyclerView(recyclerPopularTVShows, mainActivity.popularTVShow);
displayRecyclerView(recyclerTopRatedTVShows, mainActivity.topRatedTVShow);
}
private void displayRecyclerView(RecyclerView recyclerView, Object object){
LinearLayoutManager layoutManager = new LinearLayoutManager(mainActivity, LinearLayoutManager.HORIZONTAL, false);
final RecyclerViewAdapter adapter = new RecyclerViewAdapter(getActivity(), object);
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(layoutManager);
}
private void startViewPager(){
SwipeAdapter swipeAdapter = new SwipeAdapter(getActivity(), mainActivity.upcomingMovies);
viewPager.setAdapter(swipeAdapter);
}
}
As said before, is there anything that could be causing that delay to load the fragment so that I can improve it?
Thanks in advance
I tried below code to implement an expend and collapse content using recyclerview(listview) a link
final boolean isExpanded = position==mExpandedPosition;
holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);
holder.itemView.setActivated(isExpanded);
if (isExpanded)
previousExpandedPosition = position;
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mExpandedPosition = isExpanded ? -1:position;
notifyItemChanged(previousExpandedPosition);
notifyItemChanged(position);
}
});
In my case when i click the particular position in recyclerview its expanding but it goes above the recyclerview.I cant see the full expanded content.i can see only partial content.In this case i need to scroll the recyclerview to view the full content.But i am searching for a solution to view the content without scroll the recyclerview. If i click another position in recyclerview that should be placed over an recyclerview.

Try to use NestedScrollView instead of ScrollView and set below to your activity :-
recyclerView.setNestedScrollingEnabled(false);
For more information you can refer below stackoverflow links:-
How to use RecyclerView inside NestedScrollView?
Recyclerview inside ScrollView not scrolling smoothly
I have this layout in two apps, one inside a RecyclerView and the other in a root activity layout.
Here the layout:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
android:orientation="vertical"
android:layout_marginTop="4dp"
android:layout_marginBottom="4dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:background="#CFCFCF"
android:minHeight="250dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/holo_red_dark"
>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/holo_blue_bright"
android:layout_above="#+id/commerceTextView"
>
<ImageView
android:src="#drawable/imagen"
android:id="#+id/commerceImageView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"/>
</FrameLayout>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/commerceTextView"
android:gravity="center"
android:textStyle="bold"
android:textSize="24sp"
android:textColor="#F1F1F1"
android:background="#color/colorPrimary"
android:layout_alignParentBottom="true"
android:paddingTop="10dp"
android:text="Best food ever"
android:paddingBottom="10dp"/>
</RelativeLayout>
</FrameLayout>
Here the adapter
public class CommercesAdapter extends RecyclerView.Adapter<CommercesAdapter.CommercesViewHolder> {
private final Context context;
private final ImageLoader loader;
private List<CommerceEntity> commercesList;
#Inject
public CommercesAdapter(Context context, ImageLoader loader) {
this.context = context;
this.loader = loader;
}
public void setData(List<CommerceEntity> commercesList) {
this.commercesList = commercesList;
}
#Override
public CommercesViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context)
.inflate(R.layout.list_comerces_item, parent, false);
return new CommercesViewHolder(view);
}
#Override
public void onBindViewHolder(CommercesViewHolder holder, int position) {
CommerceEntity commerce = commercesList.get(position);
String imageUri = commerce.getImageUri();
String name = commerce.getName();
// holder.commerceTypeName.setText(name);
//loader.bind(holder.commerceImage, imageUri);
}
#Override
public int getItemCount() {
return commercesList.size();
}
public static class CommercesViewHolder extends RecyclerView.ViewHolder {
public ImageView commerceImage;
public TextView commerceTypeName;
public CommercesViewHolder(View itemView) {
super(itemView);
commerceImage = (ImageView) itemView.findViewById(R.id.commerceImageView);
commerceTypeName = (TextView) itemView.findViewById(R.id.commerceTextView);
}
}
Here the RecyclerView
And here in a root activity layout
Someone knows why this happen? if I add android:centerInParent"true" to the nested FrameLayout the image appears but i don't understand why.
In your adapter, uncomment the two lines that you have commented out;
`
// holder.commerceTypeName.setText(name);
//loader.bind(holder.commerceImage, imageUri);
`
I create a ListFragment for show Text & Image my code hase not any error but when i run it , it get me crash & when I see Log it don't get me any Message ?

NOTICE : I am using from appcompat_v7 .
When you use ListFragment or ListActivity then ListView id in xml must be :
android:id="#id/android:list
Change your ListView id in xml :
<ListView
android:id="#id/android:list"
Instead of
<ListView
android:id="#+id/lstview_Setting_fragment"
Note : Try to set List Adapter in onCreateView() instead of onCreate() in Fragment.
