Recycler view showing single item

Closed 2 years ago.
I need to create a Recyclerview. For that I have created an cardview model to be displayed in a recyclerview. Even though i have given match parent to the layouts, the width of cardview is not fitting the parent. Its width is showing approximately up to half of the screen(not matching parent) Do anyone can support?.please advise better way to do this.

Imagebutton doesnt work in slidinguppanel

I'm using the umano SlidingUpPanel library and I used an imagebutton in the panel but nothing happens when I click the imagebutton, I tried the imagebutton in another activity which worked perfectly. "next" is supposed to be printed to the logs when the button is pressed. I've searched all over but can't find any solution
Here's my code:
#SuppressLint("Registered")
public class NowPlaying extends Activity {
ImageButton play, pause, play_main, pause_main, next, imgbtn;
private MusicService musicSrv;
#SuppressLint("WrongViewCast")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.now_playing);
play = findViewById(R.id.play_button);
imgbtn = findViewById(R.id.imgbtn);
imgbtn.setOnClickListener(new View.OnClickListener() {
#SuppressLint("ShowToast")
#Override
public void onClick(View v) {
Log.i("oladapos", "next");
}
});
SlidingUpPanelLayout now_playing =
findViewById(R.id.slideup_nowplaying);
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
playNext();
}
});
}
//play next
private void playNext(){
musicSrv.playNext();
}
//play previous
private void playPrev(){
musicSrv.playPrev();
}
#Override
public void start() {
}
#Override
public void pause() {
}
#Override
public int getDuration() {
return 0;
}
#Override

return false;

Listview items duplicated/wrong position when scrolling

This question is been asked multiple times, but everyone has his specific usage of listview adapters (ArrayAdapter or BaseAdapter).
I searched a lot before asking this question, and this same problem happened to me before and i solved it using Holder class, and cleaning code to make it the minimum possible.
But now, i am creating another interface which contains a listview and needs a BaseAdapter to fill it using a List of Object (List).
The weird thing in my case is, if my listview contains only 4 items ( 4 rows ) then everything is ok, but if it contains more than 4, first items will be duplicated, and if i scroll down/up fast , items got wrong positions.
Here is my code :
public class OrdersAdapter extends BaseAdapter {
List<Order> ordersList;
FragmentActivity activity;
private int height;
public OrdersAdapter(FragmentActivity activity, List<Order> ordersList){
this.activity = activity;
this.ordersList = ordersList;
height = Constants.getOneThirdScreenHight(activity);
}
#Override
public int getCount() {
return ordersList.size();
}
#Override
public Order getItem(int position) {
return ordersList.get(position);
}
#Override
public long getItemId(int position) {
return ordersList.hashCode();
}
private class MyHolder{
TextView orderNumber, orderDate, menuCount, orderPrice, orderStatus, orderTelephone, orderStoreName;
ImageView orderDelete, menuPicture;
Order order, mOrder;
String numberText = activity.getResources().getString(R.string.order_number);
HashMap<String, String> map;
DatabaseReference mDatabase = FirebaseDatabase.getInstance().getReference();
}
#Override
public View getView (final int position, View convertView, ViewGroup parent) {
View vi;
final MyHolder holder;
if (convertView == null) {
LayoutInflater layoutInflater = (LayoutInflater)activity.getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
holder = new MyHolder();
vi = layoutInflater.inflate(R.layout.sent_order_item, null);
holder.order = getItem(position);
holder.mOrder = new Order();
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
layoutParams.height = height;
vi.findViewById(R.id.order_history_layout).setLayoutParams(layoutParams);
holder.orderNumber = (TextView) vi.findViewById(R.id.order_number);
holder.orderDate = (TextView) vi.findViewById(R.id.order_date);

}else{

}

}
});

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
this is the java full code
public class AllUsersAdapter extends RecyclerView.Adapter<AllUsersAdapter.UserViewHolder>{
private List<MainActivity.User> userList;
private Context context;
public AllUsersAdapter(List<MainActivity.User> userList, Context context) {
this.userList = userList;
this.context = context;
}
#Override
public UserViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.single_cardview_layout, null);
UserViewHolder userViewHolder = new UserViewHolder(view);
return userViewHolder;
}
#Override
public void onBindViewHolder(UserViewHolder holder, int position) {
MainActivity.User user = userList.get(position);
String a=user.getEmailId().toString();
holder.tvProfileName.setText(user.getProfileName());
holder.tvPhoneNumber.setText(user.getPhoneNumber());
holder.tvEmailId.setText(a);
}
#Override
public int getItemCount() {
return userList.size();
}
public static class UserViewHolder extends RecyclerView.ViewHolder {
TextView tvProfileName;
TextView tvPhoneNumber;
TextView tvEmailId;
public UserViewHolder(View itemView) {
super(itemView);
tvProfileName = (TextView) itemView.findViewById(R.id.tvProfileName);
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());
}

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
