Gallery video thumbnails load extremely slow in android recyclerview

I am trying to display all user video thumbnails from local gallery in recyclerview but it loads thumbnails very slow (it takes almost 10 seconds to load all video thumbnails). Code provided below:
VideoGalleryAdapter.java:
public class VideoGalleryAdapter extends RecyclerView.Adapter<VideoGalleryAdapter.viewHolder> {
public OnItemClickListener onItemClickListener;
Context context;
ArrayList<VideoGalleryModel> videoArrayList;
public VideoGalleryAdapter(Context context, ArrayList<VideoGalleryModel> videoArrayList) {
this.context = context;
this.videoArrayList = videoArrayList;
}
#Override
public VideoGalleryAdapter.viewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(context).inflate(R.layout.video_list, viewGroup, false);
return new viewHolder(view);
}
#Override
public void onBindViewHolder(final VideoGalleryAdapter.viewHolder holder, final int i) {
holder.videoDuration.setText(videoArrayList.get(i).getVideoDuration());
Glide.with(context).asBitmap().load(videoArrayList.get(i).getVideoThumb()).into(holder.videoThumb);
}
#Override
public int getItemCount() {
return videoArrayList.size();
}
public void setOnItemClickListener(OnItemClickListener onItemClickListener) {
this.onItemClickListener = onItemClickListener;
}
public interface OnItemClickListener {
void onItemClick(int pos, View v);
}
public class viewHolder extends RecyclerView.ViewHolder {
TextView videoDuration;
ImageView videoThumb;
public viewHolder(#NonNull View itemView) {
super(itemView);
videoDuration = itemView.findViewById(R.id.videoDuration);
videoThumb = itemView.findViewById(R.id.videoThumb);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onItemClickListener.onItemClick(getAdapterPosition(), v);
}
});
}
}
}
AddVideoActivity.java:
public class AddVideoActivity extends AppCompatActivity {

I just want to know the proper way to show video thumbnail in recyclerview and how to load it faster. If you have additional questions ask me and I will be happy to answer it. Any help would be appreciated

Since creating a video thumbnail is a heavy operation. So this is taking time.
Try commenting these lines
//Bitmap bmp = ThumbnailUtils.createVideoThumbnail(data, MediaStore.Video.Thumbnails.MINI_KIND);
//videoModel.setVideoThumb(bmp);
and load image thumbnail directly using Glide
Glide.with(context).load(new File(videoArrayList.get(i).videoUri.toString())).into(holder.videoThumb);

Fetched Firebase Data is not showing into Listview

I have created a listview where I want to put all the fetched data according to the result of the previous activity values. Like, I have a Spinner and an Edittext then a search button.
The result will be according to the spinner value and edit text value both. But it is not coming. Please help.
Below my Test class with its layout file (here the spinner and edit text present)
and The SearchResults activity, and Useradapter (model class)
Test.java
public class Test extends AppCompatActivity {

e1 = (EditText)findViewById(R.id.searchpin);
firebaseAuth = FirebaseAuth.getInstance();
firebaseUser = firebaseAuth.getCurrentUser();
final String[] bloodgroups = new String[]{"A+","A-", "B+", "B-","O+", "O-", "AB+", "AB-"};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, bloodgroups);
sp.setAdapter(adapter);
searchuser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String bloods = sp.getSelectedItem().toString();
String pin1 = e1.getText().toString();
Intent intent = new Intent(Test.this, Searchresults.class);
intent.putExtra("bloods", bloods);
intent.putExtra("pin1", pin1);
startActivity(intent);
}
});
logout.setOnClickListener(new View.OnClickListener() {

How to pass Recycler View Items into one TextView

I am trying to get a TextView value item within the RecyclerView. My RecyclerView layout file has two TextViews, one is Product Name and the other for the Quantity as you can see here
=== This is my cart_items_layout_item ===

As you can see in this Image, i use the cart class/model to pass the data to them, then i created another class called CartViewHolder i use this class to set the data into Recycler View. i want to get this values and put it in the message particularly in the SMS. i dont know how to pass it i tried several codes for it.
private void sendSmsBySIntent ()
{
//Want to set specific Phone Number here
Uri uri = Uri.parse("SET DEFAULT VALUE FOR THIS");
Intent smsSIntent = new Intent(Intent.ACTION_SENDTO, uri);
//Want to Intent the Items in Here the Product Name and the Quantity
smsSIntent.putExtra("PUT THE ITEMS HERE");
try{
startActivity(smsSIntent);
} catch (Exception ex) {
Toast.makeText(CartActivity.this, "Your sms has failed...",
Toast.LENGTH_LONG).show();
ex.printStackTrace();
}
}

you can use your List<Cart> cart model list item to send product and quantity to
sms.
private void sendSmsBySIntent (Cart model)
{
//Want to set specific Phone Number here
Uri uri = Uri.parse("SET DEFAULT VALUE FOR THIS");
Intent smsSIntent = new Intent(Intent.ACTION_SENDTO, uri);
smsSIntent.putExtra("pName",model.getProductName());
smsSIntent.putExtra("pQty",model.getQuantity());
try{
startActivity(smsSIntent);
} catch (Exception ex) {
Toast.makeText(CartActivity.this, "Your sms has failed...",
Toast.LENGTH_LONG).show();
ex.printStackTrace();
}

You need the list you sent to the adapter. Send it as a parameter to the sendSmsBySIntent() function and make a for loop where you build a String.
ie.:
private void sendSmsBySIntent (List<Cart> yourList){
StringBuilder extra = new StringBuilder();
for (int i = 0; i < yourList.size(); i++) {
//Build the string the way you want
extra.append(yourList.get(i).getName()).append(" ").append(yourList.get(i).getQuantity);
}
//Want to set specific Phone Number here
Uri uri = Uri.parse("SET DEFAULT VALUE FOR THIS");
Intent smsSIntent = new Intent(Intent.ACTION_SENDTO, uri);
//Want to Intent the Items in Here the Product Name and the Quantity
smsSIntent.putExtra(extra.toString());
try{
startActivity(smsSIntent);
} catch (Exception ex) {
Toast.makeText(CartActivity.this, "Your sms has failed...",
Toast.LENGTH_LONG).show();
ex.printStackTrace();
}
}
Edit:
I changed the function inside () , check it.
Now, when you call the function you have to pass the list you are working with. Like so: sendSmsBySIntent(placeHereYourCartList)

How to choose picture from gallery and display it in CardView when Button inside the same CardView of ReclerView is pressed

I'm creating an app where there's cardviews and in every cardview there is a button "choose picture" and a imageView and some data, I want to make the user get a photo from gallery when button "choose file" is pressed and display it and display it in the same cardview of RecyclerView.
I tried this in my MainActivity :
mButtonChooseImage = findViewById(R.id.button_choose_image);
// I got an error in this line
mButtonChooseImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
openFileChooser();
}
});
private void openFileChooser(){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent,PICK_IMAGE_REQUEST);
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
#Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK &&
data != null
&& data.getData() != null){
mImageUri = data.getData();
Picasso.with(this).load(mImageUri).into(mImageView);
}
}
I tried also in the RecyclerViewAdapter to do a function openFileChooser() but it doesn't work because i can not call onActivityResult in my recyclerViewAdapter.
how we can recover the result of onActivityResult inside an Adapter? I've read some about interfaces, but i couldn't be able trying implementing this.
this is my my activity_main layout:

}
}
}, new Response.ErrorListener() {

}
});
mRequestQueue.add(request);
}
}
and this is my ReyclerViewadapter :
public class ExampleAdapter extends RecyclerView.Adapter<ExampleAdapter.ExampleViewHolder> {
private Context mContext;
private ArrayList<ExampleItem> mExampleList;
public ExampleAdapter(Context context, ArrayList<ExampleItem> exampleList){
mContext = context;
mExampleList = exampleList;
}
#NonNull
#Override
public ExampleViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(mContext).inflate(R.layout.example_item, parent, false);
ExampleViewHolder evh = new ExampleViewHolder(v);
return evh;
}
#Override
public void onBindViewHolder(#NonNull ExampleViewHolder holder, int position) {
ExampleItem currentItem = mExampleList.get(position);
String imageUrl = currentItem.getmImageUrl();
String creatorName = currentItem.getMcreator();
String ingredients = currentItem.getMingredients();
Double likeCount= currentItem.getmLikes();
holder.mTextViewCreator.setText(creatorName);
holder.mTextViewLikes.setText("like: "+likeCount);
holder.mingredients.setText("Ingredients :"+ingredients);
Picasso.with(mContext).load(imageUrl).fit().centerInside().into(holder.mImageView);
}
#Override
public int getItemCount() {
return mExampleList.size();
}
public class ExampleViewHolder extends RecyclerView.ViewHolder{
public ImageView mImageView;
public TextView mTextViewCreator;
public TextView mTextViewLikes;
public TextView mingredients;
public Button mTakephoto;
public ExampleViewHolder(#NonNull View itemView) {
super(itemView);
mImageView=itemView.findViewById(R.id.image_view);
mTextViewCreator=itemView.findViewById(R.id.text_view_creator);
mTextViewLikes=itemView.findViewById(R.id.text_view_likes);
mingredients=itemView.findViewById(R.id.text_view_ingredients);
mTakephoto=itemView.findViewById(R.id.button_choose_image);
}
}
}
I expect that user can choose a picture from gallery when the button "choose picture" and would be dislpay it in the same Cardview where the button is presssed.
Thank you for your time in advance.

Images don't appear in RecyclerView using Firebase-UI, Firestore as database and Picasso

I am using Firebase-UI to load images from Firebase Storage url string from Firestore and shown into RecyclerView using Picasso.
I have 2 variables in the database : name and image url the name appears in the recyclerview but the image not what is the problem that makes image does not appear.

The problem lies in the fact that you have an incorrect getter for mName field in your model class. When you are using getName() as a getter, Firebase is looking after a field named name and not mName, as it is in your code now. See the difference? The correct model class should look like this:
public class Upload {
private String name;
private String imageUrl;
public Upload() {}
public Upload(String name, String imageUrl) {
this.name = name;
this.imageUrl = imageUrl;
}
public String getName() { return name; }
public String getImageUrl() { return imageUrl; }
}
The setters are not required, are always optional because if there is no setter for a JSON property, the Firebase client will set the value directly onto the field. But if you wish to use setters, the correct setters for your fields are:
public void setName(String name) { this.name = name; }
public void setImageUrl(String imageUrl) { this.imageUrl = imageUrl; }

I fixed it
the problem was not in setter and getter but it was here
Uri downloadUri = taskSnapshot.getUploadSessionUri();
it is not the right link to show i replaced it by this
Uri downloadUri = taskSnapshot.getDownloadUrl();
works perfectly
