RecyclerView not shows all items

RecyclerView not shows all items - java

I create a RecyclerView to show some test post for my app. But when i run my app i can see only the username and not the test post imageView when i have create on my resource file. I start learning today about RecyclerView and i have a lot of problems with this view.
NOTE: i don't want to show any image from any url for now, but only the image when i already save in my drawable folder. And i know when is not reason to add the getImageUrl method in the model but maybe i will need it in the production, and that's the reason when i don't remove this method
HomeActivity code:
public class HomeActivity extends AppCompatActivity {
public Uri imguri;
DatabaseReference mRef;

final FirebaseUser user = mAuth.getCurrentUser();
final ImageButton new_post = findViewById(R.id.new_post_btn);

ref.putFile(imguri)

public PostModel(String name, String imgUrl) {
this.name = name;
this.imgUrl = imgUrl;
}
public String getName() {
return name;
}
public String getImgUrl() {
return imgUrl;
}
}

Change tools:srcCompat to app:scrCompat because tools namespace is used only to preview the content in the Android studio preview tab and when you run the app, attributes with tools namespace is removed from the xml file
Check the official docs for more information on tools ns

My problem is I can access name data but image cannot be displayed.
How can I access the selected photo? I take the photos in mysql database and with the url recyclerview.

Perhaps you can pass the image as a Base64 in the Intent and create in the new Activity a Imagefile from this String.
Create as Base64 String:

RecyclerView in Android Studio shows some empty lists along with the required lists. The recycler view should display all available audio in the phone

I am trying to make a musicplayer project in Android Studio. I used RecyclerView to display all the audio files present in the phone with a music icon along with the song's name as an item. The problem is the output on certain devices change in the sense that the recycler view shows empty lists with only the music icon on the screen(that are not playable) and upon scrolling, the audio files present in the phone are displayed in the successive lists with the empty lists still at the top. Why are the empty lists displayed and that too only on some devices?

I think that if you try these modifications your lists will display properly, first add this method to your adapter:
public void updateSongs(List<Songs> newSongsList) {
this.allSongs = newSongsList;
this.notifyDataSetChanged();
}
Then in the main activity:
public class MainActivity extends AppCompatActivity implements SongsAdapter.SongsViewHolder.OnSongListener {
List<Songs> songs;
//keep reference to your adapter here, instantiate in onCreate()
SongsAdapter songsAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView recyclerView = findViewById(R.id.recyclerView);
//instantiate adapter with an empty list, update when you have data
songsAdapter = new SongsAdapter(Collections.emptyList(),MainActivity.this,MainActivity.this);
recyclerView.setLayoutManager(new LinearLayoutManager(MainActivity.this));
recyclerView.setAdapter(songsAdapter);
Dexter.withContext(this)
.withPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
.withListener(new PermissionListener() {
#RequiresApi(api = Build.VERSION_CODES.Q)
#Override
public void onPermissionGranted(PermissionGrantedResponse permissionGrantedResponse) {
songs= Songs.getSongs(getApplicationContext());
//now just update your list
songsAdapter.updateSongs(songs);
}
#Override
public void onPermissionDenied(PermissionDeniedResponse permissionDeniedResponse) {
android.os.Process.killProcess(android.os.Process.myPid());
}
#Override
public void onPermissionRationaleShouldBeShown(PermissionRequest permissionRequest, PermissionToken permissionToken) {
permissionToken.continuePermissionRequest();
}
})
.check();
}
#Override
public void onSongClick(int position) {
Songs currentSong = songs.get(position);
Intent intent = new Intent(MainActivity.this,PlaySongsActivity.class);
intent.putExtra("SongName",currentSong.getSongName());
intent.putExtra("Uri",currentSong.getUri());
MainActivity.this.startActivity(intent);

Check user online or offline icons

I have chat app and i have fragment and show in it my friends , and currently i think to add online and offline feature next to user name in my friend fragment, I wrote the code and it working without problem , But i need to add icon online or offline next to The Full name of users, In layout i added the icons but i can't control these in code, I want if user online.. online icon set visibilty visible and offline icon set visibilty invisible and i want if user offline.. online icon set invisible and offline icon set visible.. this is my problem just!
Note: The icons is ImageView...
I wrote comment above my problems in fisrt class and in layout xml..

you can use intent to pass url to other activity
like this paste belowe code where you click in cardview or in which click event your want go to other activity
Intent i = new Intent(MainActivity.this, LoginActivity.class);
i.putExtra("url", your_image_usr);
startActivity(i);
and recieve image url in your other activity like this means your imageview activity
Intent i =getIntent();
String url = i.getStringExtra("url");
and open image using this glide library to show image
compile this in your gradle file file
compile 'com.github.bumptech.glide:glide:4.0.0-RC0'
load image like this
ImageView imageView = (ImageView) findViewById(R.id.my_image_view);
GlideApp
.with(this)
.load(url)
.centerCrop()
.placeholder(R.drawable.loading_spinner)
.into(imageView);

Here is the code where i put it
class ViewHolder extends RecyclerView.ViewHolder{
public TextView ImageTitleNameView;
public TextView YearView;
public NetworkImageView networkImageView ;
public ViewHolder(View itemView) {
super(itemView);
ImageTitleNameView = (TextView) itemView.findViewById(R.id.textView_item) ;
YearView = (TextView) itemView.findViewById(R.id.textView_item1) ;
networkImageView = (NetworkImageView) itemView.findViewById(R.id.VollyNetworkImageView1) ;
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), SecondPage.class);
intent.putExtra("path", networkImageView);
startActivity(intent);
Toast.makeText(v.getContext(), "Image not found", Toast.LENGTH_SHORT).show();
}
});
}

Button located in ListView row always fired in the last row

I have a listview (not recyclerView) in which each row has a buttons,couple of textviews and an EditText.
Once I click on the specific button("editTremp") I want the EditText to go into edit mode.
My problem is: every time I press the button (no matter in wich row) it fired only on the last row in the listview, and not in the specific row where the button is located. I've seen a lot of answers but no one works for me.
how can i fix it?
this is the layout for listview_row

UPDATE:
the solution with ViewHolder works great!!
this is the new adapter code with the ViewHolder. if you have any suggestion for improvmment it will be great!
public class personalZoneAdapter extends ArrayAdapter<TrempData> {

you can use Recycleview and set custom adapter:
Adapter:
public class TestAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
Context ctx;
public ArrayList<String> mListItem;
ArrayList<String> item;
public TestAdapter(Context ctx, ArrayList<String> mListItem) {
this.ctx = ctx;
this.mListItem = mListItem;
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
final View view = LayoutInflater.from(ctx).inflate(R.layout.row_watch_company, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
ViewHolder mViewHolder = (ViewHolder)holder;
mViewHolder.button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//do your task
}
});
}
#Override
public int getItemCount() {
return 10;
}
class ViewHolder extends RecyclerView.ViewHolder {
Button button;
public ViewHolder(View rowView) {
super(rowView);
button = (Button)rowView.findViewById(R.id.button);
}
}
}
Recyclerview in fragment / activity:
rvAdvisor = (RecyclerView) view.findViewById(R.id.rvAdvisor);
rvAdvisor.setLayoutManager(new LinearLayoutManager(getActivity()));
rvAdvisor.setAdapter(new TestAdapter (getActivity());//pass data here

RecyclerView not shows all items - java

Change tools:srcCompat to app:scrCompat because tools namespace is used only to preview the content in the Android studio preview tab and when you run the app, attributes with tools namespace is removed from the xml file Check the official docs for more information on tools ns
