I am working on RecyclerView and try to using on click listener for each item of recyclcerview using Interface
Here is my Activity class:
public class LegacyHomeActivity extends ActivityBaseDrawer {
private List<LegacyVideo> legacyVideoList = null;
private List<Video> videoList = new ArrayList<>();
private RecyclerView mRecyclerView;
private LegacyModeHomeAdapter adapter;
#Override
public void onNetworkStateChanged(boolean connected) {
}
#Override
protected void onCreate(Bundle savedInstanceState) {
isLegacyMode = true;
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_legacy_home);
if (getSupportActionBar() != null) {
setTitle(getString(R.string.footy_legacy_home));
}
ImageView legacy_live_score_imageView = (ImageView) findViewById(R.id.legacy_live_score_imageView);
legacy_live_score_imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startActivity(new Intent(LegacyHomeActivity.this, LegacyLiveScoreActivity.class));
}
});
ImageView legacy_highlight_imageView = (ImageView) findViewById(R.id.legacy_highlight_imageView);
legacy_highlight_imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startActivity(new Intent(LegacyHomeActivity.this, LegacyHighlightsActivity.class));
}
});
ImageView legacy_news_imageView = (ImageView) findViewById(R.id.legacy_news_imageView);
legacy_news_imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startActivity(new Intent(LegacyHomeActivity.this, LegacyNewsActivity.class));
}
});
mRecyclerView = (RecyclerView) findViewById(R.id.legacy_mood_recyclerview);
final LinearLayoutManager layoutManager = new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.VERTICAL, false);
mRecyclerView.setLayoutManager(layoutManager);
adapter = new LegacyModeHomeAdapter(getApplicationContext(), itemClickListener);
mRecyclerView.setAdapter(adapter);
mRecyclerView.setHasFixedSize(true);
swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
swipeRefreshLayout.setColorSchemeResources(R.color.ThemeColor,
R.color.ThemeColor, R.color.ThemeColor);
swipeRefreshLayout
.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
getLegacyVideoList();
}
});
circularProgressView = (CircularProgressView) findViewById(R.id.circularProgressView);
showLoadingProgress();
getLegacyVideoList();
}
LegacyVideoClickListener itemClickListener = new LegacyVideoClickListener() {
#Override
public void onItemClickListener(int position) {
Video video = videoList.get(position);
VideoPlayerUtil.initVideoPLayer(video, LegacyHomeActivity.this);
}
};
private void getLegacyVideoList() {
FootyLightAPI api = new FootyLightAPI(getApplicationContext(), mResponseListener);
api.getLegacyHomeVideoList();
}
private final FootyLightAPI.ResponseListener mResponseListener = new FootyLightAPI.ResponseListener() {
#Override
public void getResponse(int apiId, final String response) {
switch (apiId) {
case R.integer.ApiLegacyVideoList:
Log.e("Legacy ............", "Response:................" + response);
try {
final ObjectMapper mapper = new ObjectMapper();
legacyVideoList = mapper.readValue(response, new TypeReference<List<LegacyVideo>>() {
});
if (legacyVideoList != null && legacyVideoList.size() > 0) {
videoList.clear();
for (LegacyVideo video : legacyVideoList) {
Log.e("Legacy video", "" + video.getTitle());
Video videoItem = new Video();
if (video.getItemType().equalsIgnoreCase("video")) {
videoItem.setTitle(video.getTitle());
videoItem.setLink(video.getLink());
videoItem.setThumb(video.getThumb());
videoItem.setContentType(video.getContentType());
videoItem.setContentUrl(video.getContentUrl());
videoItem.setDmcaLabel(video.getDmcaLabel());
videoItem.setDmcaContent(video.getDmcaContent());
videoItem.setDmcaDisclaimer(video.getDmcaDisclaimer());
videoItem.setDisplayType(video.getDisplayType());
videoList.add(videoItem);
}
}
}
Log.e("VideoList", "........." + videoList.size());
runOnUiThread(new Runnable() {
#Override
public void run() {
showVideoAdapter();
hideLoadingProgress();
}
});
} catch (Exception e) {
}
break;
default:
break;
}
}
#Override
public void getError(int apiId, int errorCode) {
}
#Override
public void getResponse(String trackingStr, int apiId, String response) {

#Override
public void getError(String trackingStr, int apiId, int errorCode) {
}
};
public void showVideoAdapter() {
if (adapter != null) {
adapter.setVideos(videoList);
}
}
}
And here is my Adapter Class
public class LegacyModeHomeAdapter extends RecyclerView.Adapter<LegacyModeHomeAdapter.ItemViewHolder> {
private List<Video> videoList;
private Context mContext;
private LegacyVideoClickListener onVideosRVItemClickListener;
private LayoutInflater getLayoutInflater() {
return LayoutInflater.from(mContext);
}
public LegacyModeHomeAdapter(Context mContext, LegacyVideoClickListener onVideosRVItemClickListener) {
this.mContext = mContext;
this.onVideosRVItemClickListener = onVideosRVItemClickListener;
}
public void setVideos(List<Video> videosList) {
this.videoList = videosList;
notifyDataSetChanged();
}
#Override
public ItemViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = getLayoutInflater().inflate(R.layout.layout_legacy_mode_home_video_item, parent, false);
return new ItemViewHolder(view);
}
#Override
public void onBindViewHolder(ItemViewHolder holder, final int position) {
Video video = videoList.get(position);
Picasso.with(mContext).load(video.getThumb()).into(holder.categoryImage);
holder.categoryName.setText(video.getTitle());
holder.title_image_btn.setText(video.getDisplayType());
holder.VideosItemClickListener(position, onVideosRVItemClickListener);
}
#Override
public int getItemCount() {
if (videoList != null) {
return videoList.size();
}
return 0;
}
public class ItemViewHolder extends RecyclerView.ViewHolder {
private TextView categoryName;
private ImageView categoryImage;
private Button title_image_btn;
public ItemViewHolder(View itemView) {
super(itemView);
categoryName = (TextView) itemView.findViewById(R.id.categoryName);
categoryImage = (ImageView) itemView.findViewById(R.id.categoryImage);
title_image_btn = (Button) itemView.findViewById(R.id.title_image_btn);
}
public void VideosItemClickListener(final int position, final LegacyVideoClickListener videosRVItemClickListener) {
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
videosRVItemClickListener.onItemClickListener(position);
}
});
}
}
}
And finally i am using this interface for listener :
public interface LegacyVideoClickListener {
public void onItemClickListener(int position);
}
This procedure working fine all of my other portion of app but not working this case. I don't know where is the problem . Please help me .
You this approach:
#Override
public void onBindViewHolder(final ViewHolder holder, int position) {
final String element = mDataset[position];
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//your code
}
});
}
Pass onVideosRVItemClickListener in your ItemViewHolder constructor.
#Override
public ItemViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = getLayoutInflater().inflate(R.layout.layout_legacy_mode_home_video_item, parent, false);
return new ItemViewHolder(view, onVideosRVItemClickListener);
}
#Override
public void onBindViewHolder(ItemViewHolder holder, final int position) {
Video video = videoList.get(position);
Picasso.with(mContext).load(video.getThumb()).into(holder.categoryImage);
holder.categoryName.setText(video.getTitle());
holder.title_image_btn.setText(video.getDisplayType());
}
public class ItemViewHolder extends RecyclerView.ViewHolder {
private TextView categoryName;
private ImageView categoryImage;
private Button title_image_btn;
public ItemViewHolder(View itemView, final LegacyVideoClickListener videosRVItemClickListener) {
super(itemView);
categoryName = (TextView) itemView.findViewById(R.id.categoryName);
categoryImage = (ImageView) itemView.findViewById(R.id.categoryImage);
title_image_btn = (Button) itemView.findViewById(R.id.title_image_btn);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
videosRVItemClickListener.onItemClickListener(getAdapterPosition());
}
});
}
}
Check this sample
OnCLick can be achived using Custom Interface
interface Listener {
void performOperation(int Position);
}
in Your Adapter
private Listener mListener;
In your Adapter initialize your listner in constructor like this
mListener = (Listener) context;
In your bindViewHolder method
holder.yourView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mListener.performOperation(position);
}
});
Now in your Activity implement that interface like this
public class LegacyHomeActivity extends ActivityBaseDrawer implements listner {
#Override
public void performOperation(int Position) {
//Do whatever you want to do with this position
}
}
Your interface adapter class should be like this
public class LegacyModeHomeAdapter extends RecyclerView.Adapter<LegacyModeHomeAdapter.ItemViewHolder> {
private List<Video> videoList;
private Context mContext;
public static LegacyVideoClickListener onVideosRVItemClickListener;
private LayoutInflater getLayoutInflater() {
return LayoutInflater.from(mContext);
}
public LegacyModeHomeAdapter(Context mContext, LegacyVideoClickListener onVideosRVItemClickListener) {
this.mContext = mContext;
this.onVideosRVItemClickListener = onVideosRVItemClickListener;
}
public void setVideos(List<Video> videosList) {
this.videoList = videosList;
notifyDataSetChanged();
}
#Override
public ItemViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = getLayoutInflater().inflate(R.layout.layout_legacy_mode_home_video_item, parent, false);
return new ItemViewHolder(view);
}
#Override
public void onBindViewHolder(ItemViewHolder holder, final int position) {
Video video = videoList.get(position);
Picasso.with(mContext).load(video.getThumb()).into(holder.categoryImage);
holder.categoryName.setText(video.getTitle());
holder.title_image_btn.setText(video.getDisplayType());
holder.VideosItemClickListener(position, onVideosRVItemClickListener);
}
#Override
public int getItemCount() {
if (videoList != null) {
return videoList.size();
}
return 0;
}
public class ItemViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private TextView categoryName;
private ImageView categoryImage;
private Button title_image_btn;
public ItemViewHolder(View itemView) {
super(itemView);
categoryName = (TextView) itemView.findViewById(R.id.categoryName);
categoryImage = (ImageView) itemView.findViewById(R.id.categoryImage);
title_image_btn = (Button) itemView.findViewById(R.id.title_image_btn);
itemView.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
onVideosRVItemClickListener.onItemClickListener(getPosition(), v);
}
}
public void setOnItemClickListener(LegacyVideoClickListener clickListener) {
LegacyModeHomeAdapter.onVideosRVItemClickListener = clickListener;
}
public interface LegacyVideoClickListener {
public void onItemClickListener(int position, View v);
}
}
And your adapter usage class should be like this
adapter.setOnItemClickListener(new LegacyModeHomeAdapter.LegacyVideoClickListener() {
#Override
public void onItemClick(int position, View v) {
//Your code
}
});
Using this way of interface settings you can achieve the onclick listener function exactly.
Please let me know if you are having trouble still.
class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
public Button btMyButton;
public ViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// your implementation. In order to get position you can use `getAdapterPosition()` method
}
}
#Override
public void onBindViewHolder(RecyclerViewAdapter.ItemViewHolder holder, int position) {
holder.name.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
}
Try like this

I want to set the text of a custom build popup.
As soon as I want to set the text, the classic NullPointerException comes. How can I access the text field in my custom popup? How can I change the text of the TextView order_overview_number.setText(...).
How do I have to properly initialize this? TextView order_overview_number = epicDialog.findViewById(R.id.order_overview_number);
this is Unfortunately wrong...

I have a list of words with translations in RecyclerView. I want the selected word to be highlighted, but at the same time I could use these values in Activity. I can highlight selected values or use the values of a selected item, but the combination of the both fails.
Please, maybe You see where I am wrong and can help solve my problem.
p.s. Please don’t judge me for the not enough clean code and my English, I’m learning. :)

Looks like your commented code would overwrite your click listener with one that only hightlights. Try combining them:
public MyViewHolder(#NonNull View itemView, final OnItemClickListener listener) {
super(itemView);
mTextViewEN = itemView.findViewById(R.id.myList_textView_word);
mTextViewLT = itemView.findViewById(R.id.myList_textView_translation);
imageViewLearned = itemView.findViewById(R.id.iV_learned);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (listener != null){
int position = getAdapterPosition();
if (position != RecyclerView.NO_POSITION){
selectedItem = position;
notifyDataSetChanged();
listener.onItemClick(position);
}
}
}
});
}
I was just playing around with some code, learning new things, when I ran into this problem... I'm trying to pass a variable from my RecylcerViewAdapter to a method in MainActivity, but I just can't seem to accomplish it.
I tried a lot of different thing with interfaces and casting, but nothing did the trick. Since I'm fairly new to all of this, maybe I'm making a trivial mistake somewhere?
My Interface:
public interface AdapterCallback {
void onMethodCallback(int id);
}
This is my adapter class:
public class PostAdapter extends RecyclerView.Adapter<PostAdapter.ViewHolder> {
private List<Post> postList;
private Context context;
private AdapterCallback listener;
public PostAdapter() {
}
public PostAdapter(List<Post> postList, Context context) {
this.postList = postList;
this.context = context;
}
public void setListener(AdapterCallback listener) {
this.listener = listener;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.recycler_layout, viewGroup, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull final ViewHolder viewHolder, final int position) {
viewHolder.tvTitle.setText(postList.get(position).getTitle());
viewHolder.tvBody.setText(new StringBuilder(postList.get(position).getBody().substring(0, 20)).append("..."));
viewHolder.tvId.setText(String.valueOf(postList.get(position).getUserId()));
viewHolder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int id = postList.get(position).getId();
if (listener != null) {
listener.onMethodCallback(id);
}
}
});
}
#Override
public int getItemCount() {
return postList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
TextView tvTitle;
TextView tvBody;
TextView tvId;
LinearLayout parentLayout;
public ViewHolder(View itemView) {
super(itemView);
tvTitle = itemView.findViewById(R.id.tvTitle);
tvBody = itemView.findViewById(R.id.tvBody);
tvId = itemView.findViewById(R.id.tvId);
parentLayout = itemView.findViewById(R.id.parentLayout);
}
}
}
And my MainActivity:
public class MainActivity extends AppCompatActivity {
public static final String TAG = "MainActivityLog";
private CompositeDisposable disposable = new CompositeDisposable();
#BindView(R.id.rvPosts)
RecyclerView rvPosts;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
rvPosts.setHasFixedSize(true);
rvPosts.setLayoutManager(new LinearLayoutManager(this));
populateList();
logItems();
}
private void populateList() {
MainViewModel viewModel = ViewModelProviders.of(MainActivity.this).get(MainViewModel.class);
viewModel.makeQuery().observe(MainActivity.this, new Observer<List<Post>>() {
#Override
public void onChanged(#Nullable List<Post> posts) {
PostAdapter adapter = new PostAdapter(posts, getApplicationContext());
rvPosts.setAdapter(adapter);
}
});
}
public void logItems() {
PostAdapter adapter = new PostAdapter();
adapter.setListener(new AdapterCallback() {
#Override
public void onMethodCallback(int id) {
MainViewModel viewModel = ViewModelProviders.of(MainActivity.this).get(MainViewModel.class);
viewModel.makeSingleQuery(id).observe(MainActivity.this, new Observer<Post>() {
#Override
public void onChanged(#Nullable final Post post) {
Log.d(TAG, "onChanged: data response");
Log.d(TAG, "onChanged: " + post);
}
});
}
});
}
#Override
protected void onDestroy() {
super.onDestroy();
disposable.clear();
}
}
The populateList() method works just fine, but the logItems() method is the problem.
So when i click on a view in RecyclerView I expect the log to output the title, description and ID of the post that was clicked. nut nothing happens...
So, any help would be appreciated.
Make adapter global variable i.e. a field. Use the same object to set every properties.
private PostAdapter adapter;
Replace your logItems method with this:
public void logItems() {
adapter.setListener(new AdapterCallback() {
#Override
public void onMethodCallback(int id) {
MainViewModel viewModel = ViewModelProviders.of(MainActivity.this).get(MainViewModel.class);
viewModel.makeSingleQuery(id).observe(MainActivity.this, new Observer<Post>() {
#Override
public void onChanged(#Nullable final Post post) {
Log.d(TAG, "onChanged: data response");
Log.d(TAG, "onChanged: " + post);
}
});
}
});
}
And populateList with this:
private void populateList() {
MainViewModel viewModel = ViewModelProviders.of(MainActivity.this).get(MainViewModel.class);
viewModel.makeQuery().observe(MainActivity.this, new Observer<List<Post>>() {
#Override
public void onChanged(#Nullable List<Post> posts) {
adapter = new PostAdapter(posts, getApplicationContext());
rvPosts.setAdapter(adapter);
logItems();
}
});
}
And don't call logItems() from onCreate
This is how I implement with my ListAdapters:
public class FeedbackListAdapter extends RecyclerView.Adapter<FeedbackListAdapter.ViewHolder> {
private final ArrayList<Feedback> feedbacks;
private View.OnClickListener onItemClickListener;
private View.OnLongClickListener onItemLongClickListener;
private final Context context;
public FeedbackListAdapter(ArrayList<Feedback> feedbacks, Context context) {
this.feedbacks = feedbacks;
this.context = context;
}
public void setItemClickListener(View.OnClickListener onItemClickListener) {
this.onItemClickListener = onItemClickListener;
}
public void setOnItemLongClickListener(View.OnLongClickListener onItemLongClickListener){
this.onItemLongClickListener = onItemLongClickListener;
}
public class ViewHolder extends RecyclerView.ViewHolder{
final TextView feedback, created, updated;
final LinearLayout mainLayout;
ViewHolder(View iv) {
super(iv);
/*
* Associate layout elements to Java declarations
* */
mainLayout = iv.findViewById(R.id.main_layout);
feedback = iv.findViewById(R.id.feedback);
created = iv.findViewById(R.id.created_string);
updated = iv.findViewById(R.id.updated_string);
}
}
#Override
public int getItemCount() {
return feedbacks.size();
}
#Override
#NonNull
public FeedbackListAdapter.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.fragment_feedback_table_row, parent, false);
return new FeedbackListAdapter.ViewHolder(view);
}
#Override
public void onBindViewHolder(final #NonNull FeedbackListAdapter.ViewHolder holder, final int position) {
/*
* Bind data to layout
* */
try{
Feedback feedback = feedbacks.get(position);
holder.feedback.setText(feedback.getContent());
holder.created.setText(feedback.getCreated());
holder.updated.setText(feedback.getUpdated());
holder.mainLayout.setOnClickListener(this.onItemClickListener);
holder.mainLayout.setOnLongClickListener(this.onItemLongClickListener);
holder.mainLayout.setTag(feedback.getDbID());
TypedValue outValue = new TypedValue();
context.getTheme().resolveAttribute(android.R.attr.selectableItemBackground, outValue, true);
holder.mainLayout.setBackgroundResource(outValue.resourceId);
}catch(IndexOutOfBoundsException e){
e.printStackTrace();
}
}
}
In onPopulateList you create an adaptor:
PostAdapter adapter = new PostAdapter(posts, getApplicationContext());
rvPosts.setAdapter(adapter);
However in public void logItems() { you used a different adapter
PostAdapter adapter = new PostAdapter();
adapter.setListener(new AdapterCallback() {
#Override
public void onMethodCallback(int id) {
...
}
});
Therefore the list is being populated with 1 adapter, but you are setting the listener on an unused second adapter.
The fix is to use the same adapter for both. If you make the adapater a field, and don't create a new one inside of logItems, but just set your listener it should work.
i.e.
// as a field in your class
private PostAdapter adapter;
then
// in `populateList()`
adapter = new PostAdapter(posts, getApplicationContext());
rvPosts.setAdapter(adapter);
and
// in `logItems()`
adapter.setListener(new AdapterCallback() {
#Override
public void onMethodCallback(int id) {
...
}
});
In Adapter
public class CustomerListAdapter extends RecyclerView.Adapter<CustomerListAdapter.OrderItemViewHolder> {
private Context mCtx;
ProgressDialog progressDialog;
//we are storing all the products in a list
private List<CustomerModel> customeritemList;
public CustomerListAdapter(Context mCtx, List<CustomerModel> orderitemList) {
this.mCtx = mCtx;
this.customeritemList = orderitemList;
progressDialog = new ProgressDialog(mCtx);
}

#Override
public OrderItemViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {

I want to retrieve data from my Database to a recyclerview with multiples layout. How to retrieve contents respectively according to whether it is picture or video?
I mean I don't want to give a position to my getItemView like if image == 1 to do this.
I want to retrieve different types of contents in in their particular layouts.
Ex: Like Facebook, if someone post a video and another person post a text they will be shown while scrolling.
Fragment
public class Discover extends Fragment {
private DatabaseReference mDatabaseRefAll;
private RecyclerView recyclerViewDiscover;
DiscoverRecyclerViewAdapter discoverRecyclerViewAdapter;
private ArrayList<Object> discoverItems = new ArrayList<Object>();
private ArrayList<discoverModell> objects = new ArrayList<>();
public Discover() {
// Required empty public constructor
}
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
final View view = inflater.inflate(R.layout.fragment_discover, container, false);
recyclerViewDiscover = (RecyclerView) view.findViewById(R.id.rcDiscover);
recyclerViewDiscover.setLayoutManager(new LinearLayoutManager(getActivity()));
recyclerViewDiscover.setHasFixedSize(true);
discoverRecyclerViewAdapter = new DiscoverRecyclerViewAdapter(getContext(), discoverItems, objects);
// set adapter
recyclerViewDiscover.setAdapter(discoverRecyclerViewAdapter);
recyclerViewDiscover.setItemAnimator(new DefaultItemAnimator());
return view;
}
private void loadPost() {
// loading the posts
mDatabaseRefAll = FirebaseDatabase.getInstance().getReference("Testing");
Query queryDiscover = mDatabaseRefAll;
queryDiscover.addChildEventListener(new ChildEventListener() {
#Override
public void onChildAdded(#NonNull DataSnapshot dataSnapshot, String s) {

Can anyone check if there are errors in it. here my code, If there is any error in the code please tell me? I don't know how to fix the code Search.java.
in my RecyclerItemClickListener.java
public interface RecyclerItemClickListener {

}

Here you are setting onClickListner on the same view twice. The Listener set in the onBindViewHolder will override the Listner set in the onCreateViewHolder method.
