why is my recycler view only showing 1 card

the app is used to sign up for events. Now I am unable to display more then one card in the recycler view even though there is data in the database.it only would display only the first row of data. I know this as I have deleted the first row and the app shows the new first row.
The php works as i have loaded the page and it gives me the data from the database.

It is because the LinearLayout of the card has match_parent as its layout_height and layout_width so it is taking up the whole space. Can you try to scroll the card up?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

The layout_height should be wrap_content.

Unable to make RecyclerView Width as match parent

Recycler View is only occupying 1st half of the screen no matter what I do.
Can anyone suggest how to make Recyclerview occupy full width of the screen?
This is what it displays me in Android Studio
But this is the actual output on a device. It's all wrapped to the left side of the device.

View view = inflater.inflate(R.layout.record_logs_card, null);
to

how to automatically align long text in next line in TextView under CardView

I am using a TextView under android.support.v7.widget.CardView. However, whenever I try to set a long text, TextView is not giving the full result.
List<User> userList = new ArrayList<>();
userList.add(new User(R.mipmap.ic_launcher,
"Amit", "9988776655",
"amit#sonevalley.comamit#sonevalley.comamit#sonevalley.comamit#sonevalley.comamit#sonevalley.comamit#sonevalley.com"));
This is my java code(as an example) and this shows in the app like this:
for this first one 'Amit'.
How to solve this? If the text is long then it will automatically set it to next line.
Here is my full Cardview.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp">
<android.support.v7.widget.CardView
android:id="#+id/cvSingleUser"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="12dp">
<ImageView
android:id="#+id/ivProfilePic"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_marginRight="16dp" />
<TextView
android:id="#+id/tvProfileName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp"
android:layout_toRightOf="#id/ivProfilePic" />
<TextView
android:id="#+id/tvPhoneNumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/tvProfileName"
android:layout_toRightOf="#id/ivProfilePic" />
<TextView
android:id="#+id/tvEmailId"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="false"
android:scrollHorizontally="true"
android:layout_below="#id/tvPhoneNumber"
android:layout_toRightOf="#id/ivProfilePic" />
</RelativeLayout>
</android.support.v7.widget.CardView>
and this is the snapshot of the java code:Java Snap Shot

tvPhoneNumber = (TextView) itemView.findViewById(R.id.tvPhoneNumber);
tvEmailId = (TextView) itemView.findViewById(R.id.tvEmailId);
}
}
}
Thank you.

use this :
yourTextView.append("\n anotherTextPart")

First of all - if your string will not have white spaces TextView will not able to properly arange text in multi line.
Try to set following attributes :
<TextView
...
android:maxLines="4"/>
Update here is my test that works even without flag above:
MainActivity.java:
private class ViewHolder extends RecyclerView.ViewHolder {
public TextView email;
public ViewHolder(View itemView) {
super(itemView);
email = (TextView) itemView.findViewById(R.id.tvEmailId);
}
}
private class Adapter extends RecyclerView.Adapter<ViewHolder> {
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View card = LayoutInflater.from(parent.getContext()).inflate(R.layout.user_card, parent, false);
return new ViewHolder(card);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.email.setText("test#gmail.comtest#gmail.comtest#gmail.comtest#gmail.comtest#gmail.comtest#gmail.comtest#gmail.comtest#gmail.com");
}
#Override
public int getItemCount() {
return 5;
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
.....
RecyclerView view = (RecyclerView) findViewById(R.id.recyclerView);
view.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));
view.setAdapter(new Adapter());

});
return view;
}
}
onClick method works (there is "click" toast) but nothing else happens, the is nothing in AndroidMonitor if I click dataHandler.detailsIcon.
How is it possible to put fragment in framelayout in list's element?
Edit
I forgot about commit(), so now it works but only for FrameLayout from first list's element. It doesn't matter which list's element I click, fragment MealDetails is always place in the same FrameLayout.
Probably because every FrameLayout have the same id(?) is there any way to solve it?

You have forgotten to commit() your FragmentTransaction.
If you don't commit it, nothing will happen. Android Studio should be warning about this as well.

RecycleView do not displaying the data

I have very popular question - why the data not showing in the RecycleView.
That is my Adapter:
public class CommentsAdapter extends RecyclerView.Adapter<CommentsAdapter.ViewHolder> {
private static final String TAG = "CommentsAdapter";
public ImageView mThumbView;
private List<PostComment> postCommentList;
public CommentsAdapter(List<PostComment> postCommentList) {
this.postCommentList = postCommentList;
}
#Override
public CommentsAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.post_comment_item, parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(CommentsAdapter.ViewHolder holder, int position) {
PostComment record = postCommentList.get(position);
holder.mAuthorTextView.setText(record.getUser().getFull_name());
holder.mDateTextView.setText(record.getCreated_at());
holder.mTextTextView.setText(record.getText());
}
#Override
public int getItemCount() {
Log.i(TAG + " comments size", Integer.toString(postCommentList.size()));
return postCommentList.size();
}
public void addItems(List<PostComment> postCommentList) {
this.postCommentList.addAll(postCommentList);
}
public class ViewHolder extends RecyclerView.ViewHolder {
// each data item is just a string in this case
public TextView mAuthorTextView;
public TextView mDateTextView;
public TextView mTextTextView;
public ViewHolder(View v) {
super(v);
mAuthorTextView = (TextView) itemView.findViewById(R.id.comment_author);
mDateTextView = (TextView) itemView.findViewById(R.id.comment_date);
mTextTextView = (TextView) itemView.findViewById(R.id.comment_text);
}
}
}
That is my view:
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="#+id/container"
....>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white"
android:paddingBottom="16dp"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:paddingTop="16dp">
<ImageView
android:id="#+id/comment_image"
android:layout_width="50dp"
android:layout_height="50dp"
android:scaleType="centerInside"
android:src="#drawable/cat"/>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/middleLayout"
android:layout_toRightOf="#+id/comment_image"
android:layout_marginTop="8dp">
<TextView
android:id="#+id/comment_author"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:singleLine="true"
android:text="Dark Plastic"
android:textColor="?attr/colorPrimary"
android:textSize="14dp" />
<TextView
android:id="#+id/comment_date"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="8dp"
android:layout_toRightOf="#+id/comment_author"
android:text="21 minutes"
android:textSize="14dp" />
</RelativeLayout>
<TextView
android:id="#+id/comment_text"
android:layout_width="wrap_content"
android:layout_toRightOf="#+id/comment_image"
android:layout_height="wrap_content"
android:maxLines="3"
android:layout_marginTop="8dp"
android:layout_below="#id/middleLayout"
android:text="sd"
android:textColor="#android:color/black"
android:textSize="16dp" />
</RelativeLayout>
<View
android:id="#+id/divider"
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_gravity="bottom"
android:paddingLeft="16dp"
android:paddingRight="16dp"></View>
That is how I set up the adapter:
mLayoutManager = new LinearLayoutManager(this);
mLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
post_details_comments_list.setLayoutManager(mLayoutManager);
mCommentListAdapter = new CommentsAdapter(new ArrayList<PostComment>());
post_details_comments_list.setAdapter(mCommentListAdapter);
After I set up the adapter, I the getItemCount returns the quantity of the items - so that is not null.
RecycleView layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.google.android.gms.maps.MapView
android:id="#+id/post_details_mapview"
android:layout_width="wrap_content"
android:layout_height="200dp" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/post_details_comments_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#style/TextLabelStyle"/>
</RelativeLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/post_details_comments_list"
android:layout_width="match_parent"
android:scrollbars="vertical"
android:layout_height="wrap_content">
</android.support.v7.widget.RecyclerView>
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/edit_comment"
android:hint="#string/hint_type_comment"/>
</LinearLayout>
I make the request to the server and here is the callback, where I get the results and set up the adapter:
#Override
public void onAllPostCommentsCallback(AllComments allComments) {
Log.i(TAG + " I've the comments", allComments.getPostCommentList().toString());
mCommentListAdapter.addItems(allComments.getPostCommentList());
post_details_comments_list.setAdapter(mCommentListAdapter);
mCommentListAdapter.notifyDataSetChanged();
}
But the list is not displaying.
What can be the reason?

put null inplace of parent in View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.post_comment_item, parent, false);

I've already solved the issue. The problem was that I had RecycleView inside the NestedScrollView
