I am working with a project and I am trying to fetch some link from a json data and I want to connect the link with a button in my recycleview so that whenever the button is clicked, it'll automatically connet to the respective websites. I gave user permission to interner in Manifest. So, How to connect it?

My Adapter class, Here can anybody suggest anything in the place of toast? The Toast is working fine !!!
public class ExampleAdapter extends RecyclerView.Adapter<ExampleAdapter.ExampleViewHolder> {

ExampleViewHolder exampleViewHolder = new ExampleViewHolder(view);
return exampleViewHolder;
}
#Override
public void onBindViewHolder(#NonNull ExampleViewHolder holder, int position) {
ExampleItem examplItem = marrayList.get(position);
String imageurl = examplItem.getMimgurl();
String title = examplItem.getMtitle();
String description = examplItem.getMdescription();
String date = examplItem.getMdate();
/////////////
final String newsurl = examplItem.getMurl();

textview_date = itemView.findViewById(R.id.textview_date);
/////////////////////////
button = itemView.findViewById(R.id.button);

}
}
Try to set intent for the website inside the onClickListener. Something like this:
Button button= findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String url = "http://www.YourWebsite.com"; //insert the link you prase
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
startActivity(intent);
}
});
You can use this code inside onClickListener to open it in the browser.
Uri uri = Uri.parse(newsurl);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

I've got an app which saves a number and the date it was recorded in a recycler View, however when the array is empty and then I try to save my number, the RecyclerView does not show the item. The item did save, but it isn't displayed in the view. I know it save because when I go back to the view the item is there. I have looked ages for answer online and have seen nobody with the same issue. Thank you in advance for your help!

If you could also help me figure out animating the recycler view that would be appreciated !

Change your onCreate() method inside the "Activity2" Activity to look like this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_2);
String dateString = DateFormat.format("dd/MM/yyyy",currentTime).toString();
Intent intent = getIntent();
int count = intent.getIntExtra(MainActivity.EXTRA_NUMBER,0);
loadData();
if (count!=0){
if (mexampleList == null){
mexampleList = new ArrayList<ExampleItem>();
}
String value = String.valueOf(count);
ExampleItem exampleItem = new ExampleItem(value, dateString);
mexampleList.add(0, exampleItem);
}
buildRecyclerView();
saveList();
}
I've changed the order of adding the new data to the ArrayList. This way the "new item" will be added to the list before you set the adapter. I have also extrapolated some if the code into distinct code lines. I recommend this because it will be easier to debug.
A few additional comments:
The method removeItem(int position) appears to remove the entire list from your SharedPreferences instead of what I assume you only want to remove the one item.
Also in your "MainActivity" you have two methods:
openActivity2()
and
OpenActivity2()
Firstly, Java naming convention dictates that method names begin with lower case. Secondly, this is very poor programing style to give methods indistinguishable method names.
Please help with the following problems, the problem is that the data does not want to appear in the fragment home, even though the internet condition is on

My code refresh comes from Youtube
but in the tutorial it does not use fragment, please anyone help me
You have a wrong point, that is not update the list of recycler view, the list you add value in code listdata.add(item); belong to your fragment
Please add below method in your adapter
public void addData(List<Data> data) {
listdata.addAll(data);
notifyDataSetChanged();
}
And edit AmbilData function as below
private void AmbilData() {
JsonArrayRequest aarRequest = new JsonArrayRequest(URL + "/produk.php" ,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
if (response.length()>0){
for (int i =0 ; i<response.length();i++){
try {
JSONObject data = response.getJSONObject(i);
Data item = new Data();
item.setId(data.getString("id"));
item.setJudul(data.getString("judul"));
item.setHarga(data.getString("harga"));
item.setThubnail(data.getString(URL+"/img/"+data.getString("gambar")));
listdata.add(item);
} catch (JSONException e) {

recyclerAdapter.addData(listdata);

Use temp list then addAll() method then call notifyDataSetChanged() method.
If you want to notify your adapter from a loop then you should go for notifyItemInserted() otherwise keep the notifyDataSetChanged() outside of the loop.
Like this;
for (int i =0 ; i<response.length();i++){
try {
JSONObject data = response.getJSONObject(i);
Data item = new Data();
item.setId(data.getString("id"));
item.setJudul(data.getString("judul"));
item.setHarga(data.getString("harga"));
item.setThubnail(data.getString(URL+"/img/"+data.getString("gambar")));
listdata.add(item);
recyclerAdapter.notifyItemInserted(listdata.size()-1); //To update the recyclerview one by one from a loop.
} catch (JSONException e) {
}
}
// OR
for (int i =0 ; i<response.length();i++){
try {
JSONObject data = response.getJSONObject(i);
Data item = new Data();
item.setId(data.getString("id"));
item.setJudul(data.getString("judul"));
item.setHarga(data.getString("harga"));
item.setThubnail(data.getString(URL+"/img/"+data.getString("gambar")));
listdata.add(item);
} catch (JSONException e) {
}
}
recyclerAdapter.notifyDataSetChanged(); //To update the whole recyclerview in one shot

Any help would be highly appreciated.
let see:
((Activity)mContext).finish();
The log say mContext is kind of FilePickerDelegate. So check your Adapter init function. I think you pass context as "this", but "this" reference to FilePickerDelegate. So change it to YourActivity.this ( with activity) or getActivity( in fragment)
You are passing the Application Context not the Activity Context in your adapter.
getApplicationContext();
Wherever you are passing it pass this or ActivityName.this instead.
Since you are trying to cast the Context you pass (Application not Activity as you thought) to an Activity with
(Activity)
you get this exception because you can't cast the Application to Activity since Application is not a sub-class of Activity.
Instead of Context use Activity in your adapter. As Activity can be cast to context but context can not be cast to activity.
Activity avtivity;
public MaterialAdapter(Activity activity, List<Material> albumList) {
this.activity = activity;
this.albumList = albumList;
}
In your calling activity when you initialize your adapter Call this adapter like below.
new MaterialAdapter(<your calling activity>.this, yourList);
view.getContext().startActivity(new Intent(mContext, MaterialHistoryActivity.class));
Good afternoon guys, I am trying to fetch some data from the police data website.
Unfortunately, the application doesn't show any data saying "E/RecyclerView: No adapter attached; skipping layout".
I have attached the LatestCrimesActivity, adapter and the ListItem class.
Thank you for your help.

Just try to change some lines. First set adapter before your api call.
recyclerView = (RecyclerView) findViewById(R.id.recyclerViewlatest);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
listItems=new ArrayList<>();
adapter = new MyAdapter(listItems, getApplicationContext());
recyclerView.setAdapter(adapter);
Then when you received the answer, fill listItems, then call notifyDataSetChange() method of your adapter object.
I'm using volley to load data using JSON Parsing in to a recycler view. I've used recylcer view before, but somehow, the downloaded data is persistent this time, meaning its still there after the app is closed, maybe stays in cache. I'm not sure, what I'm doing wrong here. Any help is appreciated, thanks.
Edit: The application is storing downloaded data after the app is closed, which doesn't happen when using recycler view.

This is my RecyclerView Adapter Class:
package com.example.recyclerview;

public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
public TextView title, body;
public ViewHolder(View view){

title = (TextView) view.findViewById(R.id.title);
body = (TextView) view.findViewById(R.id.body);
view.setTag(view);
view.setOnClickListener(this);
}
#Override
public void onClick(View view) {
if(itemClick != null) itemClick.onClick(view, getAdapterPosition());
}
}
public PostRecycleViewAdapter(List<PostData> postData)
{
this.postData = postData;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemLayout = LayoutInflater.from(parent.getContext()).inflate(R.layout.post_recycler_view,parent,false);
return new ViewHolder(itemLayout);
}
#Override
public void onBindViewHolder(PostRecycleViewAdapter.ViewHolder holder, int position) {
PostData data = postData.get(position);
holder.title.setText(data.getTitle());
holder.body.setText(data.getBody());
}
#Override

}
#Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);}
public void setClickListener(OnItemClick itemClick) {
this.itemClick = itemClick;
}
}
And this is the data item class:

public String getTitle() {
return title;
}
public String getBody() {
return body;
}
public int getId() {
return id;
}
}
