in my adapter I have the problem that if I have defined a String before the onClickListener I cannot change it later in the onClickListener. I can set it to invisible which works perfect however I cannot change it.
I want that if a user clicks on the image, a second image should replace the first one, but I cannot either change the image in a imageview, I suggest that it is the same problem as with the String which I cannot change.
Thanks for any help!
private List<cards> listItems;

this.listItems = listItems;
this.context = context;

public class ViewHolder extends RecyclerView.ViewHolder {
TextView name, comment, howMany;
public ImageView image;
/**

ViewHolder(#NonNull View itemView) {
super(itemView);

You should call notifyItemChanged with the corresponding position.
#Override
public void onBindViewHolder(final ViewHolder viewHolder, int position) {
final cards currentItem = listItems.get(i);
viewHolder.name.setText(currentItem.getName());
viewHolder.comment.setText(currentItem.getComment());
Picasso.get().load(currentItem.getProfileImageUrl()).into(viewHolder.image);
viewHolder.name.setText("this work"); // here it works
viewHolder.image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
viewHolder.name.setText("New text"); // this does not work
// viewHolder.name.setVisibility(View.INVISIBLE); this does work
Picasso.get().load(currentItem.getProfileImageUrl2()).into(viewHolder.image); // does not work
notifyItemChanged(position);
}
});
}
change value in you list at particular position and then notifyItemChanged(position);
in your click event write this:
currentItem.setName("abc");
notifyItemChanged(position)
In the data model you have keep a variable which indicates the current profile image.
for a example
class cards {
String name;
String comment;
....
boolean profileImageChanged;
}
then inside onBindViewHolder
#SuppressLint("SetTextI18n")
#Override
public void onBindViewHolder(#NonNull final ViewHolder viewHolder, int i) {
....
if(currentItem.profileImageChanged){
Picasso.get()
.load(currentItem.getProfileImageUrl()).into(viewHolder.image);
} else {
Picasso.get()
.load(currentItem.getProfileImageUrl2()).into(viewHolder.image);
}
viewHolder.name.setText("this work"); // here it works
viewHolder.image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
viewHolder.name.setText("New text"); // this does not work
// viewHolder.name.setVisibility(View.INVISIBLE); this does work
notifyItemChanged(position);
}
});
}
Hi you can go with this approach also.
#Override
public void onBindViewHolder(final ViewHolder viewHolder, int position) {
final cards currentItem = listItems.get(i);
viewHolder.name.setText(currentItem.getName());
viewHolder.comment.setText(currentItem.getComment());
Picasso.get().load(currentItem.getProfileImageUrl()).into(viewHolder.image);
viewHolder.name.setText("this work"); // here it works
viewHolder.image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ViewHolder viewNewHolder=viewHolder
viewNewHolder.name.setText("New text");
Picasso.get().load(currentItem.getProfileImageUrl2()).into(viewNewHolder.image);
}
});
}
I have used it its working.

There is a list of pictures made through RecyclerView. When you click on a picture while it is being transferred to the next activity, a ProgressBar should be displayed. When there is a return to the activity of the image selection, the ProgressBar also remains visible, although it must be hidden.
As I did below, the progress bar becomes invisible only in the first image, but in the rest it does not work. I can’t understand why
in my project there are such classes as:
interface
public interface ImageOnC {
void onClick(int position);
}
ImageViewHolder
public class ImageViewHolder extends RecyclerView.ViewHolder {
public ImageView imageView;
private ImageOnC imageOnC;
public ImageButton imageButton;
public ProgressBar progressBar;
public void setImageOnC(ImageOnC imageOnC) {
this.imageOnC = imageOnC;
}
public ImageViewHolder(#NonNull final View itemView) {
super(itemView);
imageView = itemView.findViewById(R.id.image_outline);
progressBar = itemView.findViewById(R.id.progr);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
imageOnC.onClick(getAdapterPosition());
progressBar.setVisibility(View.VISIBLE);
}
});
}
}
ImageAdabter
public class ImageAdabter extends RecyclerView.Adapter<ImageViewHolder> {
private Context mContext;
private List<Integer> listImages;
public ImageAdabter(Context mContext){
this.mContext = mContext;
this.listImages = getImages();
}
private List<Integer> getImages() {
List<Integer> results = new ArrayList<>();
results.add(R.drawable.outline1);
results.add(R.drawable.outline2);
results.add(R.drawable.outline3);
results.add(R.drawable.outline4);
results.add(R.drawable.outline5);
results.add(R.drawable.outline6);
results.add(R.drawable.outline7);
results.add(R.drawable.outline8);
results.add(R.drawable.outline9);
results.add(R.drawable.outline10);
return results;
}
#NonNull
#Override
public ImageViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(mContext).inflate(R.layout.item_images,parent,false);
return new ImageViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull final ImageViewHolder holder, final int position) {
holder.imageView.setImageResource( listImages.get(position));
holder.setImageOnC(new ImageOnC() {
#Override
public void onClick(int position) {
Common.PICTURE_SELECTED = listImages.get(position);
mContext.startActivity(new Intent(mContext, Colorful.class));
}
});
#Override
public void onBindViewHolder(#NonNull ImageViewHolder holder, int position, List<Object>payload){
//if so, then the progress bar only works for the first image in recyclerview
if(!payload.isEmpty()){
if(payload.get(position) instanceof Integer)
holder.progressBar.setVisibility(View.GONE);
}
else super.onBindViewHolder(holder, position, payload);
}
#Override
public int getItemCount() {
return listImages.size();
}
}
I add this to activity
private void initView() {
recyclerView = findViewById(R.id.recycle_view_images);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
adabter = new ImageAdabter(this);
recyclerView.setAdapter(adabter);
}
#Override
public void onResume() {
super.onResume();
if (adabter != null) {
adabter.notifyItemChanged(position, position);
}
}
in xml file use Progress bar visibility gone
I need to call an Interstitial in this Activity by clicking on an item in the list that comes from my Adapter.
public class SoundRecyclerAdapter extends RecyclerView.Adapter<SoundRecyclerAdapter.SoundViewHolder> {
private final ArrayList<SoundObject> soundObjects;
SoundRecyclerAdapter(ArrayList<SoundObject> soundObjects) {
this.soundObjects = soundObjects;
}
#NonNull
#Override
public SoundViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.sound_item, parent, false);
return new SoundViewHolder(itemView);
}
#Override
public void onBindViewHolder(#NonNull SoundViewHolder holder, int position) {
final SoundObject object = soundObjects.get(position);
final Integer soundID = object.getItemID();
holder.itemTextView.setText(object.getItemName());
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// I tried calling the interstitial here, but to no avail
EventHandlerClass.startMediaPlayer(v, soundID);
}
});
// Handle actions when the user presses a sound button
holder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
EventHandlerClass.popupManager(v, object);
return true;
}
});
}
#Override
public int getItemCount() {
return soundObjects.size();
}
class SoundViewHolder extends RecyclerView.ViewHolder {
final TextView itemTextView;
SoundViewHolder(View itemView) {
super(itemView);
itemTextView = itemView.findViewById(R.id.textViewItem);
}
}
}
Pass context as parameter of adapter's constructor:
private Context context;
SoundRecyclerAdapter(Context context, ArrayList<SoundObject> soundObjects) {
this.soundObjects = soundObjects;
this.context = context;
}
and use it in click handler
Use this code in the setOnClickListener() method:
mInterstitialAd = new InterstitialAd(SoundRecyclerAdapter.this);
Then add the adrequests and load the ad.
I fetched data from SERVER to populate RECYCLER view
I have an imageview in each recyclerview row
When I click that imageview, I want to load my drawable into the imageview
holder.imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Drawable placeholder = holder.imageView.getContext().getResources().getDrawable(R.drawable.app);
holder.imageView.setImageDrawable(placeholder);
}
});
The above is what I tried but it says "holder" needs to be declared final but in reality, I haven't even mentioned it in a way I could write "final holder" or whatever.
My ADAPTER code :
public class ProductsAdapter extends
RecyclerView.Adapter<ProductsAdapter.ProductViewHolder> {
private Context mCtx;
private List<Product> productList;
public ProductsAdapter(Context mCtx, List<Product> productList) {
this.mCtx = mCtx;
this.productList = productList;
}
#Override
public ProductViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(mCtx);
View view = inflater.inflate(R.layout.product_list, null);
return new ProductViewHolder(view);
}
#Override
public void onBindViewHolder(ProductViewHolder holder, int position) {
final Product product = productList.get(position);
//loading the image
Glide.with(mCtx)
.load(product.getImage())
.into(holder.imageView);
holder.textViewTitle.setText(product.getTitle());
holder.textViewShortDesc.setText(product.getShortdesc());
holder.textViewRating.setText(String.valueOf(product.getRating()));
holder.textViewPrice.setText(String.valueOf(product.getPrice()));
holder.imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Drawable placeholder = holder.imageView.getContext().getResources().getDrawable(R.drawable.app);
holder.imageView.setImageDrawable(placeholder);
}
});
}
#Override
public int getItemCount() {
return productList.size();
}
class ProductViewHolder extends RecyclerView.ViewHolder {
TextView textViewTitle, textViewShortDesc, textViewRating, textViewPrice;
ImageView imageView;
public ProductViewHolder(View itemView) {
super(itemView);
textViewTitle = itemView.findViewById(R.id.textViewTitle);
textViewShortDesc = itemView.findViewById(R.id.textViewShortDesc);
textViewRating = itemView.findViewById(R.id.textViewRating);
textViewPrice = itemView.findViewById(R.id.textViewPrice);
imageView = itemView.findViewById(R.id.imageView);
}
}
}
You can declare the holder final in the method header
public void onBindViewHolder(final ProductViewHolder holder, int position) {
Your code here
}
There are several solutions:
1) Make your holder to be final doing
#Override
public void onBindViewHolder(final ProductViewHolder holder, int position)
or using additional variable
final Holder finalHolder = holder;
holder.imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Drawable placeholder = finalHolder.imageView.getContext().getResources().getDrawable(R.drawable.app);
holder.imageView.setImageDrawable(placeholder);
}
});
2) When you set ClickListener on particular view, you are sure that only that view will trigger action, so you can use that knowledge
holder.imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
ImageView imgView = (ImageView) view;
Drawable placeholder = imgView.getContext().getResources().getDrawable(R.drawable.app);
imgView.setImageDrawable(placeholder);
}
});
If you're using View Binding in kotlin then it will work,
holder.binding.imageView.setImageDrawable(ContextCompat.getDrawable(holder.binding.imageView.context,R.drawable.medal_2)
without view binding it will be
holder.imageView.setImageDrawable(ContextCompat.getDrawable(holder.imageView.context,R.drawable.medal_2)
Hi I'm building PlaybackSupportFragment and after adding extra row below player controls, the Presenter's onClickEvent does not work, I mean does not catches at all.
ArrayObjectAdapter episodeRow = new ArrayObjectAdapter(new EpisodePresenter(mother));
for(Episode episode : episodes)
episodeRow.add(episode);
superAdapter.add(new ListRow(new HeaderItem(0, "Episodes"), episodeRow));
setAdapter(superAdapter);
and EpisodePresenter itself is (class of course extends android.support.v17.leanback.widget.Presenter):
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent) {
TextView view = new TextView(parent.getContext());
view.setLayoutParams(new ViewGroup.LayoutParams(315, 175));
view.setFocusable(true);
view.setFocusableInTouchMode(true);
view.setBackgroundColor(context.getResources().getColor(R.color.default_background));
view.setTextColor(Color.WHITE);
view.setGravity(Gravity.CENTER);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ViewHolder viewHolder, Object item) {
TextView vHolder = (TextView) viewHolder.view;
final Episode model = (Episode) item;
vHolder.setText(model.name);
vHolder.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Does not work at all
Toast.makeText(context, "dsadas", Toast.LENGTH_SHORT).show();
}
});
}
#Override
public void onUnbindViewHolder(ViewHolder viewHolder) {
}
What is a solution to that?
Fixed by using setOnEditorActionListener instead of onClickListener
