I have taken youtube-api sample app VideoListDemoActivity class for android and converted it to fragment to use in my app.
In inner class VideoListFragment the view videoBox from fragment is accessed, which returns null. In activity the view is not null but in fragment it's failing to get reference of fragment's view. I have attached code which I modified for this class.

I have 2 recycler views that have cards.They basically look the same have the same number of cards and everthing. The first one is for like viewing and other stuff and the second one is only for deleting cards. OnlongClicking a card in the first recycler view triggers the opening of the second recycler view. I wanted to add transitions in between them like what keep notes has done when a card is long clicked. Both the recycler view use the same adapter. I have set what the adapter should do based on passing context to the adapter. enter image description here this is my 1st layout having the 1st recycler view.enter image description here this is the 2nd layout having the second recycler view.I want like a seamless transition for the tool bar again just like what Google keeps has done.A simple solution would be preferred as I am very new to this stuff.

I have added the code related to the scene transititon which is in the adapter.
here is a gif of the problem when i add a scene transition
enter image description here
As u can see there are 2 pauses when going from 1st to 2nd activity 1st pause being longer 2nd one shorter. And also a pause when exiting the 2nd activity which seems to have the same duration as the 2nd pause.
I'm making a feature that pops up an empty dialog and enters comments.
The dialog consists of a RecyclerView.
And items consist of EditText.
Only one line of comments can be entered.
Pressing EnterKey dynamically creates the next comment input field.
However, when i press the enter key, two items are created.
Using the Toast message, I noticed that OnAddComment() was called twice.
Even after debugging, I am not sure why there are two.
What's the problem?
writing_comment_item.xml
<EditText

#Override

}
public class ViewHolder extends RecyclerView.ViewHolder {

public ViewHolder(#NonNull View itemView) {
super(itemView);
comment = itemView.findViewById(R.id.comment_edit);
comment.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override // IME Option NONE ( ENTER KEY)
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if(listener != null) {
listener.OnAddComment(getAdapterPosition());
}
return true;
}
});
}
public void setItem(String str) {
comment.setText(str);
}
}
public interface OnWritingCommentListener {
public void OnAddComment(int pos);
}
}
It is receiving callback 2 times. One for action ACTION_DOWN & one for action ACTION_UP when he is pressing the enter button.
if(listener != null) { if( event.getAction() == KeyEvent.ACTION_DOWN) { listener.OnAddComment(getAdapterPosition()); } }
So add comments only when action is ACTION_DOWN.
I have an API which have data like this:
{"seasons":[
{
"id":"1",
"titles":"1title1;1title2;1title3",
"url":"1url1;1url2;1url3;"
},
{
"id":"2",
"titles":"2title1;2title2;2title3",
"url":"2url1;2url2;2url3;"
}
]}
I parse it well and in parcelable class I did this for titles:
public String getTitles() {
return titles;
}
public StringBuilder getFullTitles() {
StringBuilder builder = new StringBuilder();
String[] titlesArray = getTitles().split(";");
for (String title : titlesArray) {
builder.append(title + "\n");
}
and this for url:
public String getUrlAdaptive() {
return urladaptive;
}
public StringBuilder getFullUrlAdaptiveFinal() {
StringBuilder builder2 = new StringBuilder();
String[] urlArray = getUrlAdaptive().split(";");
for (String details : urlArray) {
builder2.append(details + "\n");
}
return builder2;
}
so in my recycleview adapter I fetch titles data like this in textview:
#Override
public void onBindViewHolder(RecyclerViewHolder holder, int position) {
holder.title.setText(String.valueOf(mMoviesItems.get(position).getFullTitles()));
}
and the result that I got in my recycleview app is like this:
1title1
1title2
1title3
2title1
2title2
2title3
now you can see that this group:
1title1
1title2
1title3
refer to the first item of recycleview
and this group:
2title1
2title2
2title3
refer to the second item of recycleview
you can compare it with api to understand what I mean
what I need to do is to make each item of each group is applicable to be clicked
like when I click on 1title1 I got the url that correspond the title which is 1url1 to open it in youtube
and when I click on 1title2 I got the url that correspond the title which is 1url2 to open it in youtube
and when I click on 2title2 I got the url that correspond the title which is 2url2 to open it in youtube
and so on
it's like click items inside each of main item of recycleview
this is the code after try an answer:
#Override
public void onBindViewHolder(final RecyclerViewHolder holder, final int position) {
holder.title.setText(String.valueOf(mMoviesItems.get(position).getFullTitles()));
holder.title.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View vview) {
// here when click on each title I need to get the getFullUrlAdaptiveFinal with it to play it
}
});
}
and this is full code for series_list_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

I just try to display a toast message when onclick the above code to test the click of items and it work
but if I would like when I click on title like now so the url of same item start play
how I handle this click? in adapter itself or in activity?
Yes this is possible. Simply use an OnClickListener and set it in your onBindViewHolder().
It would look something like this:
#Override
public void onBindViewHolder(RecyclerViewHolder holder, int position) {
holder.title.setText(String.valueOf(mMoviesItems.get(position).getFullTitles()));
holder.title.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
// Toast here
}
}
}
a problem in my code arose after fixing some other bugs. My activity which "should" show detailed information of movies doesn't get displayed properly instead, just a blank activity opens.

</LinearLayout>
You should use getSupportFragmentManager().beginTransaction().add() for the first time.
Then when you added a fragment before you should use getSupportFragmentManager().beginTransaction().replace()
EDIT
public class MovieGridFragment extends Fragment {
public clickInterfaceHelper clickListener;
private GridView movieGridView;
private int index;
public List<movieData> movieDataList = new ArrayList<>();
public void setMovieDataList(List<movieData> movieDataList) {
this.movieDataList = movieDataList;
}
public void setClickListener(clickInterfaceHelper listener) {
this.clickListener = listener;
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
setHasOptionsMenu(true);
View rootView = inflater.inflate(R.layout.movie_display_fragment, container, false);
movieGridView = (GridView) rootView.findViewById(R.id.gv_movie_display);
if (movieDataList != null) {
initMovieGrid();
}
return rootView;
}
private void initMovieGrid() {
movieAdapter adapter = new movieAdapter(getActivity(), movieDataList);
adapter.notifyDataSetChanged();
movieGridView.setAdapter(adapter);
movieGridView.smoothScrollToPosition(index);
movieGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (clickListener != null)
clickListener.clickOnItem(position);
}
});
}
}
To use the fragment:
MovieGridFragment fragment = new MovieGridFragment();
fragment.setClickListener(this);
fragment.setMovieDataList(movieDataList);
getSupportFragmentManager().beginTransaction()
.add(R.id.activity_container, fragment).commit();
If you don't have the the list of movies before you use your fragment, you could use this code for fragment:
public class MovieGridFragment extends Fragment {
public clickInterfaceHelper clickListener;
private GridView movieGridView;
private int index;
public List<movieData> movieDataList = new ArrayList<>();
public void setMovieDataList(List<movieData> movieDataList) {
this.movieDataList = movieDataList;
if (movieDataList != null) {
initMovieGrid();
}
}
public void setClickListener(clickInterfaceHelper listener) {
this.clickListener = listener;
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
setHasOptionsMenu(true);
View rootView = inflater.inflate(R.layout.movie_display_fragment, container, false);
movieGridView = (GridView) rootView.findViewById(R.id.gv_movie_display);
return rootView;
}
private void initMovieGrid() {
movieAdapter adapter = new movieAdapter(getActivity(), movieDataList);
adapter.notifyDataSetChanged();
movieGridView.setAdapter(adapter);
movieGridView.smoothScrollToPosition(index);
movieGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (clickListener != null)
clickListener.clickOnItem(position);
}
});
}
}
Then create your fragment without using setMovieDataList() and when you get the movies data, use the method setMovieDataList()
public class MainActivity extends AppCompatActivity implements clickInterfaceHelper {
//...
MovieGridFragment mFragment;
//...
Create:
mFragment = new MovieGridFragment();
fragment.setClickListener(this);
getSupportFragmentManager().beginTransaction()
.add(R.id.activity_container, fragment).commit();
After you get the data:
mFragment.setMovieDataList(movieDataList);
You should prepend Intent extras with an unique identifier, but i'm not sure if this is what's causing the problem.
I'm very sorry for your effort but i'm just plain out stupid...
I opened the wrong Fragment....
I have implemented an abstract class that has a List View like so:
public abstract class ExampleListFragment extends ExampleFragment{

//Set Up the Bottom Bar
View view = super.onCreateView(inflater, container, savedInstanceState);
addList();
return view;
}
#Override

}
public void addList() {
_listView = new ListView(getActivity());
RelativeLayout.LayoutParams parms = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
parms.addRule(RelativeLayout.CENTER_HORIZONTAL);
parms.addRule(RelativeLayout.BELOW, R.id.tableLayout);
_listView.setLayoutParams(parms);
_listView.setClickable(true);
_listView.setFocusable(true);
_listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> adapterView, View view, int i, long l) {
longListClick(i);
return true;
}
});
_listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
listClick(i);
}
});
_layout.addView(_listView);
}
public abstract void longListClick(int pos);
public abstract void listClick(int pos);
}
I then have a class that inherits from this to implement the abstract methods which should be called when clicking an item in the list
public class TwitterFragment extends ExampleListFragment {
private TwitterAdapter _adapter;
//...
#Override
public void onSelected() {
_adapter = new TwitterAdapter(getActivity());
populateAdapter();
}
private void populateAdapter() {
showLoadingTweets();
new TwitterGetTimelineTask().execute(username); //fills adapter with Twitter status info...
}
#Override
public void longListClick(int pos) {
Toast toast = Toast.makeText(getActivity(),String.format("You have clicked item number: %d",pos),
Toast.LENGTH_SHORT);
toast.show();
}
#Override
public void listClick(int pos) {
Toast toast = Toast.makeText(getActivity(),String.format("You have clicked item number: %d",pos),
Toast.LENGTH_SHORT);
toast.show();
}
//...
class TwitterGetTimelineTask extends AsyncTask<String, String, String> {
//...
}
}
However, whenever I click on an Item, it does not appear to even enter onItemClick functions.
Any ideas? help much appreciated.
*EDIT*
As requested, here is the code for my Adapter
public class TwitterAdapter extends BaseAdapter {
private ArrayList<StatusDetails> _statusDetailsArrayList;
private LayoutInflater _inflater;
public TwitterAdapter(Context context) {
_statusDetailsArrayList = new ArrayList<StatusDetails>();
_inflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return _statusDetailsArrayList.size();
}
#Override
public Object getItem(int i) {
return _statusDetailsArrayList.get(i);
}
#Override
public long getItemId(int i) {
return _statusDetailsArrayList.get(i).get_id();
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
ViewHolder holder;
if (view == null) {
view = _inflater.inflate(R.layout.twitter_layout, null);
holder = new ViewHolder();
holder.img_icon = (ImageView) view.findViewById(R.id.statusImage);
holder.text_line1 = (TextView) view.findViewById(R.id.statusText);
holder.text_line2 = (TextView) view.findViewById(R.id.statusDateText);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
Bitmap bmp = _statusDetailsArrayList.get(i).get_profile();
if (bmp == null) {
holder.img_icon.setImageResource(R.drawable.ic_action_twitter);
} else {
holder.img_icon.setImageBitmap(bmp);
}
holder.text_line1.setText(_statusDetailsArrayList.get(i).get_text());
holder.text_line2.setText(_statusDetailsArrayList.get(i).get_date());
return view;
}
public void addStatus(StatusDetails details) {
_statusDetailsArrayList.add(details);
}
public void setStatuses(ArrayList<StatusDetails> details) {
_statusDetailsArrayList = details;
}
public ArrayList<StatusDetails> getEvents() {
return _statusDetailsArrayList;
}
public void removeAll() {
_statusDetailsArrayList.clear();
}
private class ViewHolder {
ImageView img_icon;
TextView text_line1;
TextView text_line2;
}
}
And if needed, the XML of the layout of each list
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/statusImage"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Status"
android:id="#+id/statusText"
android:layout_alignParentTop="true"
android:autoLink="web"
android:textColor="#android:color/white"
android:layout_toRightOf="#+id/statusImage" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_below="#id/statusText"
android:text="Date"
android:id="#+id/statusDateText"
android:layout_alignBottom="#+id/statusImage"
android:layout_toRightOf="#+id/statusImage" />
Thanks.
