Adding onClick to RecyclerView after parsing JSON data

Adding onClick to RecyclerView after parsing JSON data - javascript

I have a fragment in which reside a RecyclerView. I parsed JSON data from a webpage and showed it in this RecyclerView using tutorial: https://www.learn2crack.com/2016/02/recyclerview-json-parsing.html
Now I wish to add an onClick to the RecyclerView items. I know how to do so for static RecyclerView items but don't know to setOnClickListener in this case. For static recyclerview items, I'm using this class for onClick events.
package com.parassidhu.cdlumaths;
import android.support.v7.widget.RecyclerView;
import android.view.View;
public class ItemClickSupport {
private final RecyclerView mRecyclerView;
private OnItemClickListener mOnItemClickListener;
private OnItemLongClickListener mOnItemLongClickListener;
private View.OnClickListener mOnClickListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mOnItemClickListener != null) {
RecyclerView.ViewHolder holder = mRecyclerView.getChildViewHolder(v);
mOnItemClickListener.onItemClicked(mRecyclerView, holder.getAdapterPosition(), v);
}
}
};
private View.OnLongClickListener mOnLongClickListener = new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
if (mOnItemLongClickListener != null) {
RecyclerView.ViewHolder holder = mRecyclerView.getChildViewHolder(v);
return mOnItemLongClickListener.onItemLongClicked(mRecyclerView, holder.getAdapterPosition(), v);
}
return false;
}
};
private RecyclerView.OnChildAttachStateChangeListener mAttachListener
= new RecyclerView.OnChildAttachStateChangeListener() {
#Override
public void onChildViewAttachedToWindow(View view) {
if (mOnItemClickListener != null) {
view.setOnClickListener(mOnClickListener);
}
if (mOnItemLongClickListener != null) {
view.setOnLongClickListener(mOnLongClickListener);
}
}
#Override
public void onChildViewDetachedFromWindow(View view) {
}
};
private ItemClickSupport(RecyclerView recyclerView) {
mRecyclerView = recyclerView;
mRecyclerView.setTag(R.id.item_click_support, this);
mRecyclerView.addOnChildAttachStateChangeListener(mAttachListener);
}
public static ItemClickSupport addTo(RecyclerView view) {
ItemClickSupport support = (ItemClickSupport) view.getTag(R.id.item_click_support);
if (support == null) {
support = new ItemClickSupport(view);
}
return support;
}
public static ItemClickSupport removeFrom(RecyclerView view) {
ItemClickSupport support = (ItemClickSupport) view.getTag(R.id.item_click_support);
if (support != null) {
support.detach(view);
}
return support;
}
public ItemClickSupport setOnItemClickListener(OnItemClickListener listener) {
mOnItemClickListener = listener;
return this;
}
public ItemClickSupport setOnItemLongClickListener(OnItemLongClickListener listener) {
mOnItemLongClickListener = listener;
return this;
}
private void detach(RecyclerView view) {
view.removeOnChildAttachStateChangeListener(mAttachListener);
view.setTag(R.id.item_click_support, null);
}
public interface OnItemClickListener {
void onItemClicked(RecyclerView recyclerView, int position, View v);
}
public interface OnItemLongClickListener {
boolean onItemLongClicked(RecyclerView recyclerView, int position, View v);
}
}
My Adapter Class is:
package com.parassidhu.cdlumaths;
import android.content.ClipData;
import android.content.Intent;
import android.net.Uri;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import android.widget.Toast;
import com.parassidhu.cdlumaths.R;
import com.parassidhu.cdlumaths.Android;
import java.util.ArrayList;
public class NoticesData extends RecyclerView.Adapter<NoticesData.ViewHolder> {
private ArrayList<Android> mAndroidList;
private RecyclerView recyclerView;
public NoticesData(ArrayList<Android> androidList, RecyclerView rcl) {
mAndroidList = androidList;
recyclerView=rcl;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.notices_row, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(final ViewHolder holder, int position) {
holder.mTvName.setText(mAndroidList.get(position).getName());
ItemClickSupport.addTo(recyclerView).setOnItemClickListener(new ItemClickSupport.OnItemClickListener() {
#Override
public void onItemClicked(RecyclerView recyclerView, int position, View v) {
//I can't call Toast or startIntent here
}
});
}
#Override
public int getItemCount() {
return mAndroidList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
private TextView mTvName;
public ViewHolder(View view) {
super(view);
mTvName = (TextView)view.findViewById(R.id.tv_name);
}
}
}

In your Activity or Fragment class create a method like below
public void showToast(int position) {
Toast.makeText(getActivity(), "Clicked position is " + position, Toast.LENGTH_SHORT).show();
}
(I think you're using Fragment so I used getActivity())
Now update your Adapter constructor like this
...
...
private YourFragment frag;
public NoticesData(ArrayList<Android> androidList, RecyclerView rcl, YourFragment fragment) {
mAndroidList = androidList;
recyclerView = rcl;
frag = fragment;
}
In your Fragment update Adapter initialization like this
NoticesData notice = NoticesData(androidList, rcl, YourFragment.this);
Now call the showToast() method like below in Adapter
ItemClickSupport.addTo(recyclerView).setOnItemClickListener(new ItemClickSupport.OnItemClickListener() {
#Override
public void onItemClicked(RecyclerView recyclerView, int position, View v) {
frag.showToast(position); // it's like callback method
}
});
Note: here YourFragment means the Fragment which hosts your RecyclerView.

you must set click listener for each of the items in your recycler view from the adapter for that recycler view. when you set the data for each if the items (views) in the recycler view you can add the onClickListener for that view too.

i want to open my file when download completed

I extracted some urls by jsoup.
and made a download manager.
and it seems parcelfiledescriptor doesn't work.
i tryed regist broadcaster but did't work.

After builing my app and Installing Google Maps API, My APP crashes anytime I tend to search for Location

I am new to this programming and I am finding it difficult to get past this stage. After building APP successfully, I added Google Map to get real time Location. After doing this, my app crashes each time I click the switch button.
Please if you can help me source out the issue, I would be very happy as this will help me a lot. Below is my Logcat

You try to ask for location updates using that line
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,locationRequest,this);
The problem is that you never initialize locationRequest variable. You have next function
private void createLocationRequest() {
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setInterval(5000);
locationRequest.setFastestInterval(1000);
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}
To fix your problem add this line at the end of createLocationRequest()
this.locationRequest = locationRequest

private void createLocationRequest() {
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setInterval(5000);
locationRequest.setFastestInterval(1000);
locationRequest.setPriority (LocationRequest.PRIORITY_HIGH_ACCURACY);
this.locationRequest = locationRequest;
}
This was the solution to the problem.

Using Fused Location Provider for Wikitude

I previously used Android Location Manager to retrieve location. However, when I run wikitude apps, the POIs are loaded but are not displayed. I read a few posts saying that this may caused by basic Location Strategy. Therefore, I decided to use Fused Location Provider. The problem still occur. Please help me anyone

I am using Jquery 1.11. when i use with 'GET' instead of 'PUT' 'method' on client side and 'consumes' on server side, it works. even i tried with JSON.stringify while sending sending. i am using jackson on server side to convert data into json

Which version of jquery you are using?
If you are using jquery prior to 1.9.0 than try type: 'PUT' instead of method:'put' in your ajax call and it should work. Otherwise it should be of with method:'put' .
Check documentation for more reference http://api.jquery.com/jquery.ajax/

JavaScript is the programming language of the Web.

Adding onClick to RecyclerView after parsing JSON data - javascript

you must set click listener for each of the items in your recycler view from the adapter for that recycler view. when you set the data for each if the items (views) in the recycler view you can add the onClickListener for that view too.
