Did you try to set it as clicable and focusable?
XML
android:focusable="true"
android:clickable="true"
Java
button.setClickable("true");
button.setFocusable("true");
If nothing changes, try to put a log call in your onClick method (maybe there's something bad in the code), or in OnTouch.

How to fetch data related to a clicked item in a recyclerView from room database to a new activity?

My app has a RawMaterialFragment that displays raw materials data in a recyclerView from room database.
I am trying to build a detail activity(MetrialItemView) to show up the details of an individual raw material by clicking or selecting the raw material from the recyclerView.
my problem is how to send the data from the adapter and how to receive the data in the MetrialItemView Activity and display it.
MaterialListAdapter:
public class MaterialListAdapter extends RecyclerView.Adapter<MaterialListAdapter.ViewHolder> {
private final LayoutInflater mInflater;
private FragmentRawMaterials mContext;
private List<RawMaterialsEntity> mMaterial; // Cached copy of Materials
RawMaterialsEntity mCurrent;
public MaterialListAdapter(FragmentRawMaterials context) {
mInflater = LayoutInflater.from(context.getActivity());
mContext = context;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = mInflater.inflate(R.layout.list_item, parent, false);
return new ViewHolder(itemView);
}
public class ViewHolder extends RecyclerView.ViewHolder {
private final TextView materialName;
private final TextView materialBrand;
private final TextView materialQuantity;
LinearLayout parentLayout;
private ViewHolder(View itemView) {
super(itemView);
materialName = itemView.findViewById(R.id.raw_material_name);
materialBrand = itemView.findViewById(R.id.raw_material_brand);
materialQuantity = itemView.findViewById(R.id.raw_material_quantity);
parentLayout = itemView.findViewById(R.id.parent_layout);
}
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
if (mMaterial != null) {
mCurrent = mMaterial.get(position);
holder.materialName.setText(mCurrent.getRawMaterialName());
holder.materialBrand.setText(mCurrent.getRawMaterialBrand());
holder.materialQuantity.setText(String.valueOf(mCurrent.getRawMaterialQuantity()));
} else {
// Covers the case of data not being ready yet.
holder.materialName.setText("Name NA");
holder.materialBrand.setText("Brand NA");
holder.materialQuantity.setText("Quantity NA");
}
holder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(mContext.getContext(), MaterialItemView.class);
mContext.startActivity(intent);
}
});
}
public void setMaterial(List<RawMaterialsEntity> materials){
mMaterial = materials;
notifyDataSetChanged();
}
// getItemCount() is called many times, and when it is first called,
// mWords has not been updated (means initially, it's null, and we can't return null).
#Override
public int getItemCount() {
if (mMaterial != null)
return mMaterial.size();
else return 0;
}
}
MaterialItemView:
public class MaterialItemView extends AppCompatActivity {
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.material_item_view);
}

each row of dataModel() must have ID and then use putExtra() whan clicked It happens
holder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(mContext.getContext(), MaterialItemView.class);
intent.putExtra("ID",mCurrent.getID());
mContext.startActivity(intent);
}
});
and use getIntent() in detailActivity
int id =getIntent().getIntExtra("ID",-1);
and then get a row data in detail activity from database(viewModel)by ID and parse it

grid view items not scrolling down to up (repeating the items) and when i am loading data from server in android?

I have a grid view and data updated in grid view using api calls and grid item loads a image from url using picasso library all are perfect but when i am scrolling down to up the grid items not scrolled and repeating the items(up to down scrolling was perfect).

To avoid the unexpected behaviour , provide the implementations of
#Override
public Object getItem(int position) {
return mProducts.get(position);
}
#Override
public long getItemId(int position) {
//return position; or better to provide some unique id
// as there is one in your code, product id
return mProducts.get(position).prod_id;
}
Note : remove notifyDataSetChanged(); in getView because it will trigger the adapter to refresh all view while they are under creating which can cause this behaviour.

DialogPostFragment df= new DialogPostFragment();
df.show(getFragmentManager(), "Dialog");
}
When the button is pressed then the cardview item is clicked and ongoing back dialog is also opened.
I want to open dialog only when I press the button.
Thank You.

I had faced exactly the same issue once.This is how I solved it :
add id to the first linear layout inside the cardview :
<LinearLayout
android:id="#+id/rowLL"
android:layout_width="fill_parent"
android:layout_height="123dp"
android:background="#drawable/posts_card_bg"
android:orientation="horizontal"
android:paddingBottom="3dp"
android:paddingRight="3dp"
>
Now,in your PostCardAdapter.java :
public class PostCardAdapter extends RecyclerView
.Adapter<ContactViewHolder> {
...
private static MyClickListener myClickListener;
...
public void setOnItemClickListener(MyClickListener myClickListener) {
PostCardAdapter.myClickListener = myClickListener;
}
...
public interface MyClickListener {
public void onItemClick(int position, View v);
}
}
Then,in your ContactViewHolder.java
public class ContactViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
private PostCardAdapter.MyClickListener myClickListener;
...
public ContactViewHolder(final Context context, View itemView, PostCardAdapter.MyClickListener clickListener) {
super(itemView);
...
myClickListener = clickListener;
itemView.findViewById(R.id.rowLL).setOnClickListener(this);
}
#Override
public void onClick(View v) {
myClickListener.onItemClick(getLayoutPosition(), v);
}
}

No toast shown when item clicked RecyclerView

Ok, I know, probably someone has already asked this question. I have already found a possible solution for my problem on this link. But, for an unknown reason, that solution doesn't work for me.
I want to display a Toast when an item (a CardView) is clicked inside a RecyclerView. This Toast must show me the position of the item clicked.
When I click on a CardView I see the ripple - so that means that the card is clicked - but unfortunately, I don't see any toast. Can someone explain me why? Thanks in advance.
This is my Adapter:
public class MainRecyclerViewAdapter extends RecyclerView.Adapter<MainRecyclerViewAdapter.MyMainViewHolder> {
private List<Information> mainInfo;
MyDatabase myDatabase;
public MainRecyclerViewAdapter(List<Information> mainInfo) {
this.mainInfo = mainInfo;
}
public static class MyMainViewHolder extends RecyclerView.ViewHolder {
TextView titleTextView, notesTextView, dateTextView, timeTextView;
ImageView imageView;
LinearLayout linearLayout;
public MyMainViewHolder(View itemView) {
super(itemView);
linearLayout = (LinearLayout) itemView.findViewById(R.id.mainLayout);
imageView = (ImageView) itemView.findViewById(R.id.imgIcon);
titleTextView = (TextView) itemView.findViewById(R.id.title_TextView);
notesTextView = (TextView) itemView.findViewById(R.id.notes_TextView);
dateTextView = (TextView) itemView.findViewById(R.id.date_TextView);
timeTextView = (TextView) itemView.findViewById(R.id.time_TextView);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(v.getContext(), "Position: " + Integer.toString(getAdapterPosition()), Toast.LENGTH_LONG).show();
}
});
}
}
#Override
public MyMainViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.main_single_raw, parent, false);
MyMainViewHolder holder = new MyMainViewHolder(v);
return holder;
}
public void delete(int position){
mainInfo.remove(position);
notifyItemRemoved(position);
}
#Override
public void onBindViewHolder(final MyMainViewHolder holder, final int position) {
holder.imageView.setImageResource(mainInfo.get(position).getICON_ID());
holder.titleTextView.setText(mainInfo.get(position).getTITLE());
holder.notesTextView.setText(mainInfo.get(position).getNOTES());
holder.dateTextView.setText(mainInfo.get(position).getDATE());
holder.timeTextView.setText(mainInfo.get(position).getTIME());
}
#Override
public int getItemCount() {
return mainInfo.size();
}}

Problem solved! This is the working code:
public static class MyMainViewHolder extends RecyclerView.ViewHolder {
TextView titleTextView, notesTextView, dateTextView, timeTextView;
ImageView imageView;
LinearLayout linearLayout;
public MyMainViewHolder(final View itemView) {
super(itemView);
linearLayout = (LinearLayout) itemView.findViewById(R.id.mainLayout);
imageView = (ImageView) itemView.findViewById(R.id.imgIcon);
titleTextView = (TextView) itemView.findViewById(R.id.title_TextView);
notesTextView = (TextView) itemView.findViewById(R.id.notes_TextView);
dateTextView = (TextView) itemView.findViewById(R.id.date_TextView);
timeTextView = (TextView) itemView.findViewById(R.id.time_TextView);
itemView.setClickable(true);
itemView.setFocusableInTouchMode(true);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(itemView.getContext(), "Position: " + Integer.toString(getAdapterPosition()), Toast.LENGTH_LONG).show();
}
});
linearLayout.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Toast.makeText(itemView.getContext(), "Position: " + Integer.toString(getAdapterPosition()), Toast.LENGTH_LONG).show();
}
});
}
}
So now, if i click on the linearLayout - so on the entire cardView - I see its position!
Credits: link

Add the following line in your view.xml
android:clickable=true
Remove the following line from first LinearLayout
android:clickable="true"

try this,
#Override
public MyMainViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.main_single_raw, parent, false);
MyMainViewHolder holder = new MyMainViewHolder(v);
return holder;
}
public void delete(int position){
mainInfo.remove(position);
notifyItemRemoved(position);
}
#Override
public void onBindViewHolder(final MyMainViewHolder holder, final int position) {
holder.imageView.setImageResource(mainInfo.get(position).getICON_ID());
holder.titleTextView.setText(mainInfo.get(position).getTITLE());
holder.notesTextView.setText(mainInfo.get(position).getNOTES());
holder.dateTextView.setText(mainInfo.get(position).getDATE());
holder.timeTextView.setText(mainInfo.get(position).getTIME());
holder.titleTextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context,""+position,Toast.LENGTH_SHORT).show();
}
});
}
#Override
public int getItemCount() {
return mainInfo.size();
}}

Button doesn't get focus in Recyclerview item - android

Did you try to set it as clicable and focusable? XML android:focusable="true" android:clickable="true" Java button.setClickable("true"); button.setFocusable("true"); If nothing changes, try to put a log call in your onClick method (maybe there's something bad in the code), or in OnTouch.
