Activity to fragment Communication in Android

I am using fragment for the first time. I am trying to get List of videos from youtube present in my fragment. I am retrieving a youtube url from firebase and extract playlist id from it. This playlist id is passed as a parameter to fragment which would then list out all the videos present in the playist. i am successfully able to retrieve the playlist id in the fragment, but it changes to null in the url. Any help is appreciable.thanks in advance.

```this is the image of my logcat. It prints id and url as required, but then it changes to null

Got the answer. there was a problem in sharing data between activity and fragment. the value was being set null twice, one before and one after the function call(i dont know why but). then instead of calling newInstance() i used bundle, checked if it is null or not in fragment class and then set the value of id.
CollgeGallery.java
#Override
public void onDataChange(#NonNull DataSnapshot dataSnapshot) {
//object of College class to get getImageurls() which has the list of urls
College clg = dataSnapshot.getValue(College.class);
String playid = getYoutubeVideoId(clg.getVideourls());
//setting the list to imagegrid, passing url from this activity to imageview.
imagegrid = new CollegeImageGrid(CollegeGallery.this,clg.getImageurls());
//setting adapter to grid with the list of urls
grid_image.setAdapter(imagegrid); //check error, getCount is null, crashes application.
//extracting playlist id
// String playid = getYoutubeVideoId(clg.getVideourls());
//fragment code
setPlayid(playid);
Bundle bun = new Bundle();
YoutubeVideoList firstfrag = new YoutubeVideoList();
bun.putString("test", playid);
firstfrag.setArguments(bun);
getSupportFragmentManager().beginTransaction().add(R.id.youtube_frag, firstfrag).commit();
// FragmentTransaction tr = getSupportFragmentManager().beginTransaction();
// tr.add(R.id.youtube_frag, YoutubeVideoList.newInstance(playid)).commit();
}```
**YoutubeVideoList.java**
```#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle args = this.getArguments();
if(args != null){
id = args.getString("test");
}
}```
Thanks everyone for your help. :)

In your CollegeGallery.java in place of:
yt.newInstance(playid)
write this
YoutubeVideoList.newInstance(playid)
Also remove the static String id from your YoutubeVideoList fragment if it's useless

Show function data without blinking with Volley in Android Studio

Recently I am working on Android project with Volley for registration and for further operation, I can make function for insertion and other one is for retrieval data. When insert button click 'Insert' function called and data has been inserted to database through volley, and at the same time retrieval function also called. But when USER clicked the button and function called then data showed(database inserted data) with blinking effect, look like loading.
I want to get rid of that effect. I want to show data smoothly without any blinking effect. I do searching but can not find any solution. Please suggest me solution I'am newbie so kindly short and efficient required.

android studio getting data from php database and populating the activity

i'm trying to get the data from the database to fill the activity with them but i'm not getting anything this is the db code i have 2 Textvies 1 image view i'm trying to fill with the data i'm new to mobile programming so need help:
public void gettypedet(final int tid, final TextView ttitle, final ImageView timg, final TextView desc) {
String url = "http://192.168.0.114/mobileshop/product_typrbyid.php?id="+tid;

}
this is my php code i tested it and it's working so shouldn't be the problem:
<?php
require_once("connection.php");
$id=$_GET["id"];
$q="Select * from product_type where id='$id'";
$res=mysqli_query($con,$q);
while($row=mysqli_fetch_assoc($res)){
$types[]=$row;
}
echo (json_encode($types));
mysqli_free_result($res);
?>
this is the activity code here not sure if i did something wrong:
public class ptype_detail extends Activity {
int kposition,tposition,id;
TextView ttitle,tdes;
ImageView timg;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

How to stop receiving data from a web server?

I have an Activity that receives and displays information from the web server and saves it to the database and, if it has already received the information once, it will read from the database.
There is no problem running the program, only when the user enters the activity and still does not receive the information from the server, exit the activity, in another Activity the application crashes.
This problem is to quit the activity because when staying in activity and loaded data completely, we have not any problems. also when reading data from the database we have not any problems.
How can stop receive data when the user quit the activity or solve this problem form another way.
This is my activity codes:

First of all you should think about your architecture. Handling fetching data inside an Activity is not a good practice. Look at MVVM or MVP and try to put your data fetching logic in another layer.
For your specific problem you should try to cancle the request in the onStop() method of the Activity, see:

How to pass value from recyclerview item to another activity

I'm trying to pass the value in recyclerview item to another activity when we click the recyclerview item. Here I use the OnItemTouchListener.
I retrieve data from JSON and parse it into ArrayList. I save 5 parameters. Title, ID, Rating, ReleaseDate, urlPoster, but right now i only show 2 parameters, Title, and image from urlposter.
I want to pass the other parameters to another activity, but i can't find out how to do that.
There's another question similar like this (Values from RecyclerView item to other Activity), but he uses OnClick, not OnItemTouch, and he do that in the ViewHolder. I read somewhere in the internet that it's not the right thing to do.
Here's my code
public class Tab1 extends Fragment {
private static final String ARG_PAGE = "arg_page";
private static final String STATE_MOVIES = "state movies";
private TextView txtResponse;
private String passID;
// Progress dialog

// temporary string to show the parsed response

You need to add those other two values to a bundle in the intent. So something like this:
Intent intent = new Intent(getActivity(), YourNextActivity.class);
intent.putExtra("movie_id_key", movies.get(position).getId); //you can name the keys whatever you like
intent.putExtra("movie_rating_key", movies.get(position).getRating); //note that all these values have to be primitive (i.e boolean, int, double, String, etc.)
intent.putExtra("movie_release_date_key", movies.get(position).getReleaseDate);
startActivity(intent)
And in your new activity just do this to retrieve:
String id = getIntent().getExtras().getString("movie_id_key");

Add them as extras in the intent with which you start the activity:
Intent intent = new Intent(currentActivity, targetActivity);
// Sree was right in his answer, it's putExtra, not putStringExtra. =(
intent.putExtra("title", title);
// repeat for ID, Rating, ReleaseDate, urlPoster
startActivity(intent);
then pull them out in the onCreate of the other activity with
Intent startingIntent = getIntent();
String title = startingIntent.getStringExtra("title"); // or whatever.
In response to the comment below:
I'm not 100% sure how you implemented it, but it looks like you have onclick handlers that pass a position and a view reference, right? Adapt it as you like, but basically...:
public void onClick(View v, int position){
Movie m = movies.get(position);
Intent intent = new Intent(v.getContext(), AnotherActivity.class);
intent.putExtra("my_movie_foo_key", m.getFoo());
intent.putExtra("my_movie_bar_key", m.getBar());
// etc.
v.getContext().startActivity(intent);
}
As long as you have a valid context reference (and they couldn't click on a view without a valid context), you can start an activity from wherever you like.
