How do I refresh the RecyclerView when an image is clicked? - android

I know this questions has been asked in the past. For some reason I can't seem to get it to work even though I tried using
understoodLanguageListAdapter.notifyDataSetChanged();
in my Activity file. Here is my code
Fragment file containing RecyclerView.
<android.support.v7.widget.RecyclerView
android:id="#+id/color_list"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Item layout:
<TextView
android:id="#+id/colorText"
android:layout_height="wrap_content" />
<ImageView
android:id="#+id/colorImage"
android:layout_height="wrap_content"
android:clickable="true"
android:visibility="visible"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:srcCompat="#drawable/icn_close_bluepurple" />
Adapter code:
public class ColorsListAdapter extends RecyclerView.Adapter {
Context context;
List<String> list;
public ColorsListAdapter(Context context, List<String> list) {
this.context = context;
this.list = list;
}
#NonNull
#Override
public MyViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.colors_item,parent, false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
holder.textView.setText(list.get(position));
holder.imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
ColorsManager colorsManager = new ColorsManager();
colorsManager.deleteFromColorsList(holder.textView.getText().toString());
}
});
}
#Override
public int getItemCount() {
return list.size();
}
class MyViewHolder extends RecyclerView.ViewHolder {
TextView textView;
ImageView imageView;
public MyViewHolder(View itemView) {
super(itemView);
textView = (TextView) itemView.findViewById(R.id.colorText);
imageView = (ImageView) itemView.findViewById(R.id.colorImage);
}
}
}
Activity code is as follows:
RecyclerView recyclerView;
List<String> list;
UnderstoodLanguageListAdapter understoodLanguageListAdapter;
---
---
#Override
protected void initialize(Bundle savedInstanceState) {
recyclerView = (RecyclerView) findViewById(R.id.color_list);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
ColorsManager colorsManager = new ColorsManager();
list = colorsManager.getUnderstoodLanguageList();
colorsListAdapter = new ColorsListAdapter(this, list);
recyclerView.setAdapter(colorsListAdapter);
}
Any advice/tips about the fix is much appreciated.
Thank you!

You should change in adapter class like replace bellow code
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
holder.textView.setText(list.get(position));
holder.imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
ColorsManager colorsManager = new ColorsManager();
colorsManager.deleteFromColorsList(holder.textView.getText().toString());
}
});
}
class MyViewHolder extends RecyclerView.ViewHolder {
TextView textView;
ImageView imageView;
public MyViewHolder(View itemView) {
super(itemView);
textView = (TextView) itemView.findViewById(R.id.colorText);
imageView = (ImageView) itemView.findViewById(R.id.colorImage);
}
}
with new code
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
holder.textView.setText(list.get(position));
}
class MyViewHolder extends RecyclerView.ViewHolder {
TextView textView;
ImageView imageView;
public MyViewHolder(View itemView) {
super(itemView);
textView = (TextView) itemView.findViewById(R.id.colorText);
imageView = (ImageView) itemView.findViewById(R.id.colorImage);
imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
int pos = getAdapterPosition();
ColorsManager colorsManager = new ColorsManager();
colorsManager.deleteFromColorsList(list.get(pos));
notifyItemRemoved(pos);
}
});
}
}

You should try notifyItemRemoved(position)

First of all you have to let adapter know that some changes has been made in certain position, to achieve that you need to use some callback (Listener), which has to be passed from your View -> Adapter -> ViewHolder or something similar.

You are creating new instance of ColorManager every time user clicks ImageView.
This new instance is obviously different from one that you used in initialize().
So, the item in new instance is updated and not the list that you passed to recycler adapter

Android on click set imageview

so I have an android project that makes use of recyclerview and cardview, where I set a background imageview on click of a card. This is my code:
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.Viewholder> {
private ArrayList <Integer> mImages = new ArrayList<>();
public RecyclerViewAdapter( Context mContext, ArrayList<Integer> mImages) {
this.mImages = mImages;
}
#NonNull
#Override
public Viewholder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.itemlist,viewGroup,false);
return new Viewholder(view);
}
#Override
public void onBindViewHolder(#NonNull final Viewholder viewholder, int i) {
viewholder.img.setImageResource(mImages.get(i));
}
#Override
public int getItemCount() {
return mImages.size();
}
public class Viewholder extends RecyclerView.ViewHolder implements View.OnClickListener{
ImageView img;
ImageView imv;
public Viewholder(#NonNull View itemView) {
super(itemView);
img = itemView.findViewById(R.id.imgview);
imv = itemView.findViewById(R.id.imageView4);
itemView.setOnClickListener(this);
}
#Override
public void onClick(View view) {
Log.d("TEST", "Clicked");
int position = getLayoutPosition();
imv.setImageResource(R.drawable.vehicles);
}
}
}
But it doesn't work on click and the app just crashes. How do I resolve this issue?
You must define your itemView as clickable for receiving click events.
android:clickable="true"
please try move onClickListener to onBindViewHolder
#Override
public void onBindViewHolder(#NonNull final Viewholder viewholder, int i) {
viewholder.img.setImageResource(mImages.get(i));
viewholder.img.setOnClickListener(v -> {
// your code
});
}
Please try
itemView.setOnClickListener(new View.OnClickListener{
#Override
public void onClick(View view){
//your code
}
});

Android RecyclerView onClick in different Activity

Everything works well and my onClick in my recyclerView is working in getting the positions of my items, but what my design calls for is to be able to click an item of the recyclerView and open up a new activity (as a popover or pop up). I can achieve this but my problems comes with the information I need to display on the popover. The information comes like this inside the activity (inside a Firebase value call)
attributeList.removeAll(attributeList);
for (DataSnapshot child : dataSnapshot.child("Attribute").getChildren()){
Attribute attribute = child.getValue(Attribute.class);
attribute_list newAttributeList = new attribute_list( attribute.Name + ": " + attribute.Value);
attributeList.add(newAttributeList);
}
attributeAdapter = new attribute_list_adapter(attributeList, getContext());
recyclerAttribute.setAdapter(attributeAdapter);
This works perfectly for displaying the information, but there's more then just a "value" and a "name" associated with the click.
Basically when I select an item, I need to get the position of the item clicked (which I have) and compare it to the position inside attributeList so I can call a Firebase call (or pass the data somehow) to the popover to display values from the "Attribute" class (such as Name, Value, Description, and another list (recyclerView).
My recyclerView:
public class attribute_list_adapter extends RecyclerView.Adapter<attribute_list_adapter.ViewHolder> {
private List<attribute_list> listItems;
private Context context;
public attribute_list_adapter(List<attribute_list> listItems, Context context) {
this.listItems = listItems;
this.context = context;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext())
.inflate(R.layout.attribute_list, parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
attribute_list listItem = listItems.get(position);
holder.txtTitle.setText(listItem.getTxtTitle());
}
#Override
public int getItemCount() {
return listItems.size();
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
public TextView txtTitle;
public ViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
txtTitle = (TextView) itemView.findViewById(R.id.txtTitle);
}
#Override
public void onClick(View v) {
}
}
}
This is example:
public class attribute_list_adapter extends RecyclerView.Adapter<attribute_list_adapter.ViewHolder> {
private List<attribute_list> listItems;
private Context context;
public attribute_list_adapter(List<attribute_list> listItems, Context context) {
this.listItems = listItems;
this.context = context;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext())
.inflate(R.layout.attribute_list, parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.itemView.setOnClickListener(new View.onClickListener() {
#Override
public void onClick(View v) {
onItemClickListener.onItemClick(position);
}
});
}
#Override
public int getItemCount() {
return listItems.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
TextView txtberita;
ImageView imgberita;
TextView txtnama;
public ViewHolder(View itemView) {
super(itemView);
txtnama = (TextView) itemView.findViewById(R.id.txtnama);
txtberita = (TextView) itemView.findViewById(R.id.txtberita);
imgberita = (ImageView) itemView.findViewById(R.id.imgberita);
}
}
public void setOnItemClickListener(OnItemClickListener onItemClickListener){
this.onItemClickListener = onItemClickListener;
}
OnItemClickListener onItemClickListener;
public interface OnItemClickListener{
void onItemClick(int position);
}
}
your Activity. in Oncreate()
public class TestActivity extends AppCompatActivity implements attribute_list_adapter.OnItemClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
attribute_list_adapter adapter = new attribute_list_adapter(listItems, this);
adapter.setOnItemClickListener(this);
}
#Override
public void onItemClick(int position) {
// code here
}
}
Create an interface something like
public interface OnSingleItemClickListener{
void onSingleItemClick(int position);
}
Then implement it on your ViewHolder like this
public class ViewHolder extends RecyclerView.ViewHolder implements OnSingleItemClickListener {
public ViewHolder(View itemView) {
super(itemView);
}
#Override
void onSingleItemClick(int position){
if(listItems.get(position) == listItems.get(getAdapterPosition)){
// TODO do something here
}
}
now on your OnBindViewHolder inside your adapter you must do this.
holder.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
holder.onSingleItemClick(position);
}
}):

RecyclerView programmatically click - performClick

i'm searching function that programmatically click method. so i found some method. 'performClick()'
like that :
recyclerView.findViewHolderForAdapterPosition(position).itemView.performClick();
but it dosen't work in my case. I can't find solution. How do i use the performClick in Activity???
my Adapter - ViewHolder:
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private TextView virtNo;
private TextView score01;
private TextView score02;
private TextView score03;
private TextView totalScore;
private LinearLayout linearLayout;
public ViewHolder(View itemView) {
super(itemView);
this.virtNo = (TextView) itemView.findViewById(R.id.tv_virtNo);
this.score01 = (TextView) itemView.findViewById(R.id.tv_score01);
this.score02 = (TextView) itemView.findViewById(R.id.tv_score02);
this.score03 = (TextView) itemView.findViewById(R.id.tv_score03);
this.totalScore = (TextView) itemView.findViewById(R.id.tv_totalScore);
this.linearLayout = (LinearLayout) itemView.findViewById(R.id.ll_item_score);
virtNo.setOnClickListener(this);
score01.setOnClickListener(this);
score02.setOnClickListener(this);
score03.setOnClickListener(this);
score10.setOnClickListener(this);
}
#Override
public void onClick(View v) {
onClickListener.onClick(v, getAdapterPosition(), items.get(getAdapterPosition()));
}
}
public void setOnClickListener(OnClickListener<Score> onClickListener) {
this.onClickListener = onClickListener;
}
public interface OnClickListener<T> {
void onClick(View v, int position, T item);
}
my Adapter - onBindViewHolder
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
Score item = items.get(position);
holder.virtNo.setText(item.virtNo);
holder.score01.setText(item.score01);
holder.score02.setText(item.score02);
holder.score03.setText(item.score03);
holder.totalScore.setText(itemSum(item));
}
}
I have tried to keep things easy to understand here, it is a complete example for listening to click event on individual items in RecyclerView, there are other ways to do it as well. This code works, You may modify it as it fits you, in case you have any question write them in comments. code is also available at GitHub
public class RecyclerViewOneActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_recycler_view_one);
initializeUI();
}
private void initializeUI() {
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.RecyclerViewOneActivity_RecyclerView);
RecyclerView.LayoutManager linearLayoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(linearLayoutManager);
ArrayList<String> strings = new ArrayList<>();
strings.add("first");
strings.add("second");
MyAdapter adapter = new MyAdapter(getApplicationContext(), strings);
recyclerView.setAdapter(adapter);
}
private class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {
private Context context;
private ArrayList<String> strings;
private LayoutInflater layoutInflater;
public MyAdapter(Context context, ArrayList<String> strings) {
this.context = context;
this.strings = strings;
layoutInflater = LayoutInflater.from(this.context);
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = layoutInflater.inflate(R.layout.single_item_recycler_view_one, parent, false);
MyViewHolder myViewHolder = new MyViewHolder(view);
return myViewHolder;
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
final String text = this.strings.get(position);
holder.textView.setText("" + text);
holder.linearLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, ""+text, Toast.LENGTH_SHORT).show();
}
});
}
#Override
public int getItemCount() {
return strings.size();
}

Can any one please help me
Thanks in advance :)
I have create a sample project using your code onClickListener working fine.Like when i click on item shows me the clicked item position in Log.

if you are still facing the problem download the sample project from link below.
https://www.dropbox.com/s/xf3y8oxok0zlgxk/RecyclerViewOnClick.zip?dl=0
pls see jcobs ans it may help you
RecyclerView recyclerView = findViewById(R.id.recycler);
recyclerView.addOnItemTouchListener(
new RecyclerItemClickListener(context, new RecyclerItemClickListener.OnItemClickListener() {
#Override public void onItemClick(View view, int position) {
// do whatever
}
})
);
implement your code in onitemclick.
happy coding :)
You can handle it by setting on click listener to your parent view. Recyclerview don't provide you default item click listner same as listview.
So create object of your parent layout and set it click listner.
Your holder initialization.
class UserListHolder extends RecyclerView.ViewHolder {
RelativeLayout layoutMain;
UserListHolder(View itemView) {
layoutMain = (RelativeLayout)itemView.findViewById(R.id.layoutSquadItem);
}
}
public void onBindViewHolder(RecyclerView.ViewHolder viewHolder,final int position) {
((UserListHolder)viewHolder).layoutMain.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//handle click
}
});
}
You can also refer recycler view on click listner

android recyclerview item clicks

I have created a recyclerView in my android project.I have 11 items.Each one consists of an imageview and two textviews.When I Click on any of the items it should go to their corressponding activity.How do I accomplish that.Below is the code of my recyclerView adapter.Please help me.
RecyclerAdapter.java:
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
/**
* Created by Sabudaniel61 on 2015-10-15.
*/
public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder> {
HotelData[] hoteldata;View view;
RecyclerAdapter(HotelData[] hoteldata){
this.hoteldata=hoteldata;
}
#Override
public RecyclerAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View view= LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.recyclerlayout,null);
ViewHolder viewHolder = new ViewHolder(view);
return viewHolder;
}
#Override
public void onBindViewHolder(RecyclerAdapter.ViewHolder viewHolder, int i) {
viewHolder.imageView.setImageResource(hoteldata[i].getImageUrl());
viewHolder.textView1.setText(hoteldata[i].getHotel());
viewHolder.textView2.setText(hoteldata[i].getPlace());
}
#Override
public int getItemCount() {
return hoteldata.length;
}
public class ViewHolder extends RecyclerView.ViewHolder{
TextView textView1,textView2;ImageView imageView;
public ViewHolder(View itemLayoutView) {
super(itemLayoutView);
textView1=(TextView) itemLayoutView.findViewById(R.id.textView1);
textView2=(TextView) itemLayoutView.findViewById(R.id.textView2);
imageView=(ImageView) itemLayoutView.findViewById(R.id.imageView1);
}
}
}
In your RecyclerAdapter make a onclicklistener.
private final OnClickListener mOnClickListener = new MyOnClickListener();
#Override
public MyViewHolder onCreateViewHolder(final ViewGroup parent, final int position) {
View view= LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.recyclerlayout,null);
view.setOnClickListener(mOnClickListener);
return new MyViewHolder(view);
}
The onClick method:
#Override
public void onClick(final View view) {
int itemPosition = mRecyclerView.getChildPosition(view);
String item = mList.get(itemPosition);//if you want to pass the data
//Navigate to your desired activity.
}
This is the simplest method.
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
TextView textView1,textView2;ImageView imageView;
public ViewHolder(View itemLayoutView) {
super(itemLayoutView);
textView1=(TextView) itemLayoutView.findViewById(R.id.textView1);
textView2=(TextView) itemLayoutView.findViewById(R.id.textView2);
imageView=(ImageView) itemLayoutView.findViewById(R.id.imageView1);
itemLayoutView.setOnClickListener(this);
}
#Override
public void onClick(View v) {
Intent intent = new Intent(mContext, ContentDetails.class);
itemView.getContext().startActivity(intent);
}
}
try this
You can populate recyclerview like this:
first of all, in your layout, put an id for the linearlayout
<LinearLayout
android:orientation="horizontal"
android:id="#+id/linearView" //add this line
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="20dp"
android:layout_height="20dp"
android:id="#+id/imageView1"
android:layout_gravity="top" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:id="#+id/textView1"
android:textStyle="bold"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_gravity="top"
android:layout_marginLeft="10dp" />
</LinearLayout>
the layout above will be called from your adapter on onCreateViewHolder function.
then, call the linear layout you have created on your viewHolder class:
public class ViewHolder extends RecyclerView.ViewHolder{
TextView textView;ImageView imageView;LinearLayout linearLayout;
public ViewHolder(View itemLayoutView) {
super(itemLayoutView);
textView1=(TextView) itemLayoutView.findViewById(R.id.textView1);
imageView=(ImageView) itemLayoutView.findViewById(R.id.imageView1);
linearLayout=(LinearLayout) itemLayoutView.findViewById(R.id.linearView);
}
}
finally, set onclicklistener to your recyclerview item like this:
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
//i use arraylist of type Hotel instead of array
final Hotel hotel = HotelData.get(position);
holder.textView1.setText(hotel.getName());
//if you want to add clicklistener to recyclerview item
holder.linearLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//you can call activity here
}
});
//if you want to add click listener to textview inside recyclerview item
holder.textView1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.class,"textview clicked",Toast.LENGTH_LONG).show();
}
});
}
put an interface inside the adapter and call it from activity:
private ArrayList<Inbox> list;
private Activity context;
private onItemClickedListener onItemClickedListener;
public InboxListAdapter(Activity context, ArrayList<Inbox> list) {
this.list = list;
this.context = context;
}
public class ViewHolder extends RecyclerView.ViewHolder {
private ImageView image;
private TextView name;
private TextView date;
private ImageButton btn_play;
private ImageButton btn_share;
public ViewHolder(View itemLayoutView) {
super(itemLayoutView);
image = (ImageView) itemLayoutView.findViewById(R.id.image);
name = (TextView) itemLayoutView.findViewById(R.id.name);
date = (TextView) itemLayoutView.findViewById(R.id.date);
}
}
#Override
public InboxListAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
View itemLayoutView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.row_inbox_list, parent, false);
ViewHolder viewHolder = new ViewHolder(itemLayoutView);
return viewHolder;
}
From activity
InboxListAdapter adapter = new InboxListAdapter(getActivity(), list);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL, false);
mRecyclerView.setLayoutManager(layoutManager);
mRecyclerView.setAdapter(adapter);
adapter.setOnItemClickedListener(new InboxListAdapter.onItemClickedListener() {
#Override
public void onItemClicked(Inbox inbox) {
}
});
