btnLike.setImageDrawable(context.getResources().getDrawable(R.drawable.ic_heart_red));
Toast.makeText(context, "Clicked at index ", Toast.LENGTH_SHORT).show();
}
});
but result is
means the image resource of btnLike is not changed in current card but as I shuffle cards and see on the other card the image resource of btnLike is changed any suggestions how to see that bit of code so that it can work properly...

in this i need to display our output as 3 items in each aspect-ratio mobile.
but I'm unable to achieve that. If I'm opening in big screen mobile then it's showing 3.5 items and in small device some times it's showing 2.75 items.
Kindly help me in that how to achieve that exact output.

My recycler view doesn't show all items that it has, how can I fix it?

I have something wrong with recyclerView. It doesn't show all items. For example, recyclerView has 12 items, but it shows like 10 with a half items. I can set paddingBottom for it, and it shows all items, but I don't think it is a good way. How can I fix it? I think maybe it becouse of my buttons above it.

Try adding app:layout_constraintBottom_toBottomOf="parent" in the recycler view and also make the height of the recycler view to be 0dp (match_constraint).

Android - OnClick inside gridview row

I'm trying to launch a activity from a button inside my gridview item, meaning that when user click on gridview Item it should do one function and when the user click on the button inside the gridview item it should do another function, let me elaborate, here is my single item layout that is being populated inside of my gridview;

app:civ_shadow_radius="10" />
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toRightOf="#+id/imgFood">

</RelativeLayout>
here is how the above layout looks:
and here is my adapter getview from where I try to do the intent/actions from;
#Override
public View getView(int position, View view, ViewGroup viewGroup) {
View row = view;
ViewHolder holder = new ViewHolder();
if (row == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(layout, null);
holder.txtName = (TextView) row.findViewById(R.id.txtName);
holder.txtPrice = (TextView) row.findViewById(R.id.studentid);
holder.imageView = (CircularImageView) row.findViewById(R.id.imgFood);
holder.dit = (Button) row.findViewById(R.id.editit);
final ViewHolder finalHolder = holder;
holder.dit.setOnClickListener(new View.OnClickListener() {
String getname = finalHolder.txtName.getText().toString();
String gethandicap = finalHolder.txtPrice.getText().toString();
#Override
public void onClick(View v) {
// Do something
Intent editintent = new Intent(context, MainActivity.class);
editintent.putExtra("studentname", getname);
editintent.putExtra("studentid", getID);
context.startActivity(editintent);
}
});
row.setTag(holder);
} else {
holder = (ViewHolder) row.getTag();
}
Sudentdb student = studentsList.get(position);
holder.txtName.setText(student.getName());
holder.txtPrice.setText(student.getID());
if (student.getImage() != null && student.getImage().length > 0) {
Glide.with(context)
.load(student.getImage())
.into(holder.imageView);
} else {
holder.imageView.setImageBitmap(null);
}
return row;
}
The problem I'm having is that the button inside the gridview item is not performing any actions, in log it only says ACTION_DOWN and since I added a button inside the item the item onclick also doesn't work.
EDIT; ADDING GRIDVIEW ONCLICK AND LAYOUT
gridView = (GridView) findViewById(R.id.gridView);
list = new ArrayList<>();
adapter = new StudentListAdapter(this, R.layout.food_items, list);
gridView.setAdapter(adapter);
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String dataFromGrid;
dataFromGrid = ((TextView)(view.findViewById(R.id.txtName))).getText().toString();
Intent i = new Intent(getApplicationContext(), Student.class);
i.putExtra("unfromstudent",dataFromGrid);
startActivity(i);
gridview layout (I have tried focusable and clickable)

Your Grid View XML will be Like this.
<GridView
android:id="#+id/grid"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusable="true">
</GridView>

I don't have enough reputation so i can't comment your question, why don't you use a recyclerview with a gridLayoutManager? You can see a basic example here .
After that you can implement your recyclerview adapter this way:
public class StudentsAdapter extends RecyclerView.Adapter<StudentsAdapter.ViewHolder> {
private final OnStudentItemClickListener mListener;
private Context mContext;
private List<Student> mStudents;
public StudentsAdapter(Context context, List<Student> items, OnStudentItemClickListener listener) {
mContext = context;
mStudents =items;
mListener = listener;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.list_item_student, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(final ViewHolder holder, int position) {
Student student = mStudents.get(position);
holder.mTextName.setText(student.getName());
holder.mTextPrice.setText(student.getID());
if (student.getImage() != null && student.getImage().length > 0) {
Glide.with(context)
.load(student.getImage())
.into(holder.imageView);
} else {
holder.imageView.setImageBitmap(null);
}
}
#Override
public int getItemCount() {
return mStudents.size();
}
public interface OnStudentItemClickListener {
void onStudentItemClick(Student student);
void onStudentButtonClick(Student student);
}
public class ViewHolder extends RecyclerView.ViewHolder
implements View.OnClickListener {
TextView mTextName;
TextView mTextPrice;
CircleImageView mImageView;
Button mDit;
public ViewHolder(View view) {
super(view);
mTextName = (TextView) view.findViewById(R.id.txtName);
mTextPrice = (TextView) view.findViewById(R.id.studentid);
mImageView = (CircleImageView) view.findViewById(R.id.imgFood);
mDit = (Button) view.findViewById(R.id.editit);
mDit.setOnClickListener(view1 -> {
if (null != mListener) {
mListener.onStudentButtonClick(mStudents.get(getAdapterPosition()));
}
});
itemView.setOnClickListener(this);
}
#Override
public void onClick(View view) {
if (null != mListener) {
mListener.onStudentItemClick(mStudents.get(getAdapterPosition()));
}
}
}
}

Items get mixed up when changing xml attributes using the adapter class in recycle view in android

I have an adapter class which loads items dynamically and shows them in a RecyclerView. My problem is that when I swipe up and down the recycler view the images get mixed and are shown in wrong positions (i.e. in other item's view).
For example, I have an item X and another item Y. Now when I swipe up and down the image which was to be shown in item Y get shown in item X and the same happens with other attributes.
Here is my adapter class:
public class NewsAdapter extends RecyclerView.Adapter<NewsAdapter.NewsViewHolder> {
private DatabaseReference refDNewsTable= FirebaseDatabase.getInstance().getReference().child("news_feeds");
private StorageReference refStorage = FirebaseStorage.getInstance().getReferenceFromUrl("firebase_url_comes_here");
private Context mContext;
private List<NewsModel> newsList;
public class NewsViewHolder extends RecyclerView.ViewHolder {
public TextView nHeading, nDes,nDaTi;
public ImageView nImg;
public NewsViewHolder(View view) {
super(view);
nHeading = (TextView) view.findViewById(R.id.tv_newsHeadline);
nDes = (TextView) view.findViewById(R.id.tv_nDes);
nImg = (ImageView) view.findViewById(R.id.iv_nImg);
nDaTi=(TextView) view.findViewById(R.id.tv_nDaTi);
}
}
public NewsAdapter(Context mContext, List<NewsModel> newsList) {
this.mContext = mContext;
this.newsList = newsList;
}
#Override
public NewsViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.news_model, parent, false);
return new NewsViewHolder(itemView);
}
#Override
public void onBindViewHolder(final NewsViewHolder holder, int position) {
NewsModel news = newsList.get(position);
holder.nHeading.setText(news.getnHeading());
if(news.hasDes()) {
holder.nDes.setText(news.getnDes());
}else{
holder.nDes.setVisibility(View.GONE);
}
if(news.hasImg()){
// Reference to an image file in Firebase Storage
StorageReference imgReference =refStorage.child(news.getnId());
// Load the image using Glide
Glide.with(mContext)
.using(new FirebaseImageLoader())
.load(imgReference)
.into(holder.nImg);
}else{
holder.nImg.setVisibility(View.GONE);
}
holder.nDaTi.setText(news.getnDaTi());
}
public void downloadFile(final NewsViewHolder holder){
try {
final File localFile = File.createTempFile("images", "jpg");
refStorage.getFile(localFile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
#Override
public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
Bitmap bitmap = BitmapFactory.decodeFile(localFile.getAbsolutePath());
holder.nImg.setImageBitmap(bitmap);
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
}
});
} catch (IOException e ) {}
}
#Override
public int getItemCount() {
return newsList.size();
}
}
And this is my news_model.xml file:

setOnClickListener not firing with custom adapter and custom ListView

I've been spending a few hours on a problem and I still can't figure it out. The setOnClickListener in HotelOverviewFragment is not firing when I click an item in my ListView. However, the setOnClickListener does work from my custom adapter (NowArrayAdapter).
My question is: why the setOnClickListener not working in HotelOverviewFragment (Class where the ListView is shown)?
Here's a list of what I've tried:
Setting android:focusable="false", android:focusableInTouchMode="false", android:descendantFocusability="blocksDescendants" in the hotel_row_layout.xml and fragment_hotel_overview.xml.
Setting android:clickable on true and false. Both didn't work.
Changing from BaseAdapter implementation to arrayAdapter.
I tried different listeners in HotelOverviewFragment: setOnClickListener, setOnItemClickListener, setOnItemSelectedListener and setOnTouchListener. Unfortunately, none of those worked for me.
Here's my code:
Custom adapter
public class NowArrayAdapter extends ArrayAdapter<String> {
private Context context;
private ArrayList<String> values;
private Typeface typeface;
private static Hashtable fontCache = new Hashtable();
private LayoutInflater inflater;
private TextView item;
public NowArrayAdapter(Context context, ArrayList<String> commandsList) {
super(context, R.layout.hotel_row_layout, commandsList);
this.context = context;
values = new ArrayList<String>();
values.addAll(commandsList);
typeface = getTypeface(this.context, "fonts/Roboto-Light.ttf");
inflater = LayoutInflater.from(this.context);
}
static Typeface getTypeface(Context context, String font) {
Typeface typeface = (Typeface)fontCache.get(font);
if (typeface == null) {
typeface = Typeface.createFromAsset(context.getAssets(), font);
fontCache.put(font, typeface);
}
return typeface;
}
public View getView(int position, View convertView, ViewGroup parent) {
String myText = getItem(position);
if(convertView == null) {
convertView = inflater.inflate(R.layout.hotel_row_layout, parent, false);
item = (TextView) convertView.findViewById(R.id.maps_button);
item.setTypeface(typeface);
convertView.setTag(item);
} else {
item = (TextView) convertView.getTag();
}
item.setText(myText);
//myListItem.descText.setTextSize(14);
convertView.setOnClickListener(new View.OnClickListener() {
// WORKS!
#Override
public void onClick(View view) {
Log.d("click", "Don't look at me!");
}
});
return convertView;
}
}
Fragment
public class HotelOverviewFragment extends Fragment {
private static Hashtable fontCache = new Hashtable();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_hotel_overview, container, false);
ListView list = (ListView) v.findViewById(android.R.id.list);
// Set up listview and buttons
setUp(v, list);
// Inflate the layout for this fragment
return v;
}
static Typeface getTypeface(Context context, String font) {
Typeface typeface = (Typeface)fontCache.get(font);
if (typeface == null) {
typeface = Typeface.createFromAsset(context.getAssets(), font);
fontCache.put(font, typeface);
}
return typeface;
}
public void setUp(View v, ListView l){
TextView address = (TextView) v.findViewById(R.id.content);
TextView header = (TextView) v.findViewById(R.id.header);
TextView hotelName = (TextView) v.findViewById(R.id.hotelName);
Typeface typeface = getTypeface(getActivity(), "fonts/Roboto-Light.ttf");
address.setText("some street \nZipCode, City \nCountry \nEmail \nphoneNumber");
address.setTypeface(typeface);
header.setText("Hotel info");
header.setTypeface(typeface);
header.setTextSize(20);
hotelName.setText("Hotel name");
hotelName.setTypeface(typeface);
// Set up button
ArrayList<String> n = new ArrayList<String>();
n.add(0, "More info");
// Show button
NowArrayAdapter adapter = new NowArrayAdapter(getActivity(), n);
l.setAdapter(adapter);
// THIS IS THE STUFF I'VE BEEN TRYING
try {
l.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d("click", "Success");
}
});
l.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.d("click", "Success");
}
});
l.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Log.d("click", "Success");
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
l.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
Log.d("click", "Success");
return false;
}
});
}catch (Exception e){
Log.d("click", e + "");
}
}
}

Thanks in advance.

Thanks to Daniel Nugent's suggestion I got it working. Removing the convertView.setOnClickListener() is part of the answer. I think it was blocking the other listeners in the HotelOverviewFragment.
My next mistake was that I used setOnClickListener on a ListView for testing.
setOnClickListener should be used for buttons not ListViews.
So after removing setOnClickListener all the other listeners started working.
Thanks for your time.
