How to fix TextView being rendered blank on new Activity

How to fix TextView being rendered blank on new Activity - java

I'm trying to start another activity after clicking on a CardView inside a RecyclerView. The new activity renders after the click on any of the items inside the RecyclerView (It does the transition and changes the title TextView), but it does not show any of the TextView's inside the CardView on the layout.
The OnClick method is being set as an interface and being implemented in the first Activity.
Here is my first activity. I'm loading the data here from a SQLite database, but it's not relevant for the question to show the code from it.
public class MainActivity extends AppCompatActivity implements RecipeAdapterMain.OnCardListener {
private TextView tv;
ArrayList<RecipeObject> recipes = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView rv = findViewById(R.id.recipeListMain);
LinearLayoutManager llm = new LinearLayoutManager(this);
rv.setLayoutManager(llm);
RecipeAdapterMain adapter = new RecipeAdapterMain(recipes, this);
rv.setAdapter(adapter);
tv = findViewById(R.id.title);
}
#Override
public void onCardClick(int position) {
Intent intent = new Intent(this, RecipeActivity.class);
startActivity(intent);
}
}
This is my Adapter.
public class RecipeAdapterMain extends RecyclerView.Adapter<RecipeAdapterMain.RecipeListViewHolder> {
RecyclerView mRecyclerView;
ArrayList<RecipeObject> recipeList;
private OnCardListener mOnCardListener;
public RecipeAdapterMain(Context context, ArrayList<RecipeObject> recipeList, OnCardListener onCardListener) {
this.mOnCardListener = onCardListener;
this.recipeList = recipeList;
}
#Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
mRecyclerView = recyclerView;
super.onAttachedToRecyclerView(recyclerView);
}
#Override
public RecipeListViewHolder onCreateViewHolder(ViewGroup parent, int i) {
View layoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_recipe_main, parent, false);
RecipeListViewHolder rcv = new RecipeListViewHolder(layoutView, mOnCardListener);
return rcv;
}
#Override
public void onBindViewHolder(#NonNull RecipeListViewHolder holder, int position) {
holder.mName.setText(recipeList.get(position).getName());
}
#Override
public int getItemCount(){
return recipeList.size();
}
public class RecipeListViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
public TextView mName;
OnCardListener onCardListener;
public RecipeListViewHolder(final View view, OnCardListener onCardListener) {
super(view);
mName = view.findViewById(R.id.textViewTitle);
this.onCardListener = onCardListener;
view.setOnClickListener(this);
}
#Override
public void onClick(View v) {
onCardListener.onCardClick(getAdapterPosition());
}
}
public interface OnCardListener {
void onCardClick(int position);
}
}
My second activity:
public class RecipeActivity extends AppCompatActivity {
#Override
public void onCreate(#Nullable Bundle savedInstanceState, #Nullable PersistableBundle persistentState) {
super.onCreate(savedInstanceState, persistentState);
setContentView(R.layout.layout_recipe);
}
}
This is the layout from the second activity. (layout_recipe):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/textViewName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is a test"
android:textColor="#1A1A1A"
android:textSize="18sp" />
<TextView
android:id="#+id/textViewIngr"
android:layout_width="wrap_content"

android:text="This is a test"
android:textColor="#1A1A1A"
android:textSize="18sp" />
</LinearLayout>
</androidx.cardview.widget.CardView>
</LinearLayout>
And this is the layout from the first activity (activity_main):
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"

<androidx.recyclerview.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/recipeListMain"
android:scrollbars="vertical">
</androidx.recyclerview.widget.RecyclerView>
<com.google.android.material.floatingactionbutton.FloatingActionButton

android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:layout_margin="16dp"
android:layout_marginBottom="16dp"
android:contentDescription="#string/submit"

app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:onClick="openActivityCreate"/>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
From clicking in a Card on the MainActivity, I expected to render the second activity with it's TextViews (This is a test), but it's rendering a blank page instead.

try removing #Nullable PersistableBundle persistentState from onCreate on your second activity

Add ArrayLIst to Recyclerview

I have an AlertDialog in it there used to be a ListView in which the contents of the ArrayList were displayed. For beauty, I decided to replace it with Recyclerview, Card and the problems started.
Items are added to ArrayList <String> mainListWord during the work and they should be included in the Recyclerview cards. The problem is that either the entire list falls into one card at once, or each next card contains the previous elements + 1. For example: the first card: 1 element, the second card: 2 elements, etc.
How to implement it so that when a new element is added to the array, it will be placed in its own card?

Widget layout from Activity still appear after fragment add transaction

I have a problem with fragments. I add fragments dynamically without removing old fragments so they can be recalled when I return. But when I applied the following snippet I found that some of the views that came from the activity did not disappear, such as the Button, TextView, and so on. The results I get are overlapping views
MainActivity.Java
public class MainActivity extends AppCompatActivity implements BlankFragment.OnFragmentInteractionListener {

unbinder = ButterKnife.bind(this);
fragmentManager = this.getSupportFragmentManager();
}
public void openFragment(View view) {
BlankFragment fragment = BlankFragment.newInstance("Test 1");
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_right, R.anim.enter_from_right, R.anim.exit_to_right);
transaction.addToBackStack(null);
transaction.add(R.id.dynamic_fragment_frame, fragment, "BLACK_FRAGMENT");
transaction.commit();
}
#Override

Everything went smoothly but the result of my Mainactivity layout still appeared on fragment. Please help me
Result as shows as below:

here 2

In activity_reading, the fragment container view (dynamic_fragment_frame) is declared first, so the button and the text view will be displayed on top of it. If you move the fragment container to the bottom, the fragments will be displayed correctly, so the layout should look something like this:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"
android:text="Ini Judul"

<FrameLayout
android:id="#+id/dynamic_fragment_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#00d9ff"
tools:context=".MainActivity">
<FrameLayout
android:id="#+id/dynamic_fragment_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<TextView
android:id="#+id/title_read_news"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Ini Judul"
android:textAppearance="#style/TextAppearance.AppCompat.Large"
android:layout_gravity="center"
android:paddingBottom="5dp"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:onClick="openFragment"
android:text="Open"

</RelativeLayout>
With the above layout, Imagine that the TextView and Button are over the FragmeLayout. So when you add a Fragment to the FrameLayout, the TextView and Button are still over the FragmeLayout. To hide these views, you should use TextView.setVisibility(View.GONE) and Button.setVisibility(View.GONE) when adding a Fragment

android recyclerview show data only at first time

I have a problem ,I create recyclerview and its work fine at the first search data from api , it display fine but when I try to search with new data ( second time ) it is not display anything i try to test and debug every every thing work fine and new data enter to adapter and get the result fine and set adapter to recyclerview but it is not showing any thing

Try to create an adapter once and then update items
Add next code to your adapter class
ArrayList<DeliveryReportResource> listDeliveryReport = new ArrayList<DeliveryReportResource>();
public DeliveryReportAdapter(Context context) {
this.context = context;
}
public void updateItems(List<DeliveryReportResource> list) {
listDeliveryReport.clear();
listDeliveryReport.addAll(list);
notifyDataSetChanged();
}
Then create adapter once in onCreate() and place it as global variable
And now you should call adapter.updateItems(...) every time you want to change data

RecyclerView create views with x amount of rows

I want to create dynamic views with x number of rows for each CardView that gets created. To help illustrate my idea this image shows what I essentially want to do.
For each CardView I want to be able to put any amount of TableRows into the CardView. So one CardView could have 4 rows whereas the next CardView could have 2 rows and so on.
EDIT: Implementation
Essentially this view is replicated several times, I would like to minimise having to write seperate layouts for each CardView with x amount of rows like in the Card Storage implemenation which is more reusable than what I currently have. As I hit the limit here, I have posted a pastebin of the current layout with rows that I have

If number of rows per card view is less then you can inflate edit text and add it to linear layout.
Note : It's a bad practice to add scroll view inside a scroll view
