Display buttons dynamically in recyclerview android studio

I am working on a student tracker app and I am trying to display dynamic buttons that get created under each of my students. I will paste an image below of what I hope for it to look like.
At the moment, I am hardcoding the buttons for the first image. I am getting the picture of the student and their name from my firbase db. Now my questions is how can I generate the checkBox for each of the student's and make sure it's directly under their picture and name like above.
In my mind, I am thinking the algorithm would be something like
Loop through my Students ArrayList
Generate the checkBox for each student
Place them onto my recyclerView.
I will paste relevant code down below.

Change the code of your student_item.xml to this :
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
</androidx.cardview.widget.CardView>
<RelativeLayout

android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5dp"
tools:layout_editor_absoluteX="0dp"
tools:layout_editor_absoluteY="52dp">
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_marginTop="50dp"
android:paddingTop="20dp"
android:scaleType="centerCrop" />
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/imageView"
android:layout_margin="10dp"
android:textSize="16sp" />
<CheckBox
android:id="#+id/passc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/textView"
android:text="pass" />
<CheckBox
android:id="#+id/failc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/textView"
android:layout_toRightOf="#+id/passc"
android:text="fail" />
</RelativeLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
and control the behaviour of the checkboxes from RecyclerAdapter.class

Try this:
<CheckBox
android:id="#+id/checkBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="PASS"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="#+id/recyclerView"
app:layout_constraintHorizontal_bias="0.046"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.499"
android:visibility="gone" />
<CheckBox
android:id="#+id/checkBox2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="FAIL"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.261"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.499"
android:visibility="gone" />
and
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, int position) {
//TextView
holder.textView.setText(studentsArrayList.get(position).getName());
Glide.with(mContext).load(studentsArrayList.get(position).getImageUrl()).into(holder.imageView);
if (studentsArrayList.get(position).displayButtons()) { //check if you need the buttons or not
holder.checkBox.setVisibility(View.VISIBLE);
holder.checkBox2.setVisibility(View.VISIBLE);
} else {
holder.checkBox.setVisibility(View.GONE);
holder.checkBox2.setVisibility(View.GONE);
}
}

Step 1: Add the recyclerview in one xml file.
Step 2: The elements that must be inside a reecyclerview in another xml file (Here add a button that you need).
Step 3: Link these two xml files.
Thus after each insertion dynamically a button will be added.
Hope you will find the solution.

Add Check Boxes in student_item.xml instead daily_grading.xml

How to limit the height of a RecyclerView inside a NestedScrollView

Within my current Android application, I have a screen that displays an android.support.v4.app.DialogFragment.
This DialogFragment view contains the following UI components
HEADING
== Sub Heading
== NestedScrollView
==== RecyclerView
==== RadioGroup
==== Spinner
==== EditText
==== Action Buttons
The DialogFragment is configured to be Full Screen using Style as follows:-
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NO_TITLE, R.style.AppDialogTheme);
}
My dialog style is
<!-- Define your custom dialog theme here extending from base -->
<style name="AppDialogTheme" parent="Theme.AppCompat.Light.Dialog">
<!-- Define color properties as desired -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#000</item>
<item name="android:textColorHighlight">#color/background_url</item>
<item name="colorAccent">#color/dark_grey</item>
<item name="colorControlNormal">#color/colorPrimaryDark</item>
<!-- Define window properties as desired -->
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowBackground">#android:color/white</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowCloseOnTouchOutside">false</item>
</style>
The reason I employ a NestedScrollView is so that the View will work in both Portrait and Landscape mode.
I wish to limit the height of the RecyclerView
The closest I have got is using the layout below.

By using weightSum on the inner LinearLayout of the NestedScrollView I can limit the height of the Recyclerview. However the NestedScrollView height is far too large, with more than half its height being blank.
How can I limit the height of my RecyclerView and get NestedScrollView to wrap_content?
I've tried NestedScrollView with height wrap_content but this has no effect.
How can I achieve the desired UI? Thanks in advance!

Instead of having a NestedRecyclerView, I would like to suggest to have a header and a footer added to your RecyclerView which will nicely place the overall content as far as I have seen your layout. I want to provide you a link to my answer here where you can find how to add a footer and a header along with your RecyclerView.
Hence, I would like to suggest to create a view with headline_literal and the divider and use this as a header whereas the RadioGroup, EditText and the Button will be in the footer. Let me know if you face any problem with it.
I have tried to implement the behavior that you want by myself and let me know if the following implementation works for you. I have added this in Github as well.
Let us first declare an adapter for adding a header and a footer to the RecyclerView.
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import java.util.ArrayList;
public class RecyclerViewWithHeaderFooterAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private static final int FOOTER_VIEW = 1;
private static final int HEADER_VIEW = 2;
private ArrayList<String> data; // Take any list that matches your requirement.
private Context context;
// Define a constructor
public RecyclerViewWithHeaderFooterAdapter(Context context, ArrayList<String> data) {
this.context = context;
this.data = data;
}
// Define a ViewHolder for Header view
public class HeaderViewHolder extends ViewHolder {
public HeaderViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Do whatever you want on clicking the item
}
});
}
}
// Define a ViewHolder for Footer view
public class FooterViewHolder extends ViewHolder {
public FooterViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Do whatever you want on clicking the item
}
});
}
}
// Now define the ViewHolder for Normal list item
public class NormalViewHolder extends ViewHolder {
public NormalViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Do whatever you want on clicking the normal items
}
});
}
}
// And now in onCreateViewHolder, you have to pass the correct view
// while populating the list item.
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v;
if (viewType == FOOTER_VIEW) {
v = LayoutInflater.from(context).inflate(R.layout.list_item_footer, parent, false);
FooterViewHolder vh = new FooterViewHolder(v);
return vh;
} else if (viewType == HEADER_VIEW) {
v = LayoutInflater.from(context).inflate(R.layout.list_item_header, parent, false);
HeaderViewHolder vh = new HeaderViewHolder(v);
return vh;
}
// Otherwise populate normal views
v = LayoutInflater.from(context).inflate(R.layout.list_item_normal, parent, false);
NormalViewHolder vh = new NormalViewHolder(v);
return vh;
}
// Now bind the ViewHolder in onBindViewHolder
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
try {
if (holder instanceof NormalViewHolder) {
NormalViewHolder vh = (NormalViewHolder) holder;
vh.bindView(position);
} else if (holder instanceof FooterViewHolder) {
FooterViewHolder vh = (FooterViewHolder) holder;
} else if (holder instanceof HeaderViewHolder) {
HeaderViewHolder vh = (HeaderViewHolder) holder;
}
} catch (Exception e) {
e.printStackTrace();
}
}
// Now the critical part. You have return the exact item count of your list
// I've only one footer. So I returned data.size() + 1
// If you've multiple headers and footers, you've to return total count
// like, headers.size() + data.size() + footers.size()
#Override
public int getItemCount() {
if (data == null) {
return 0;
}
if (data.size() == 0) {
// Return 1 here to show nothing
return 1;
}
// Add extra view to show the header view
// Add another extra view to show the footer view
// So there are two extra views need to be populated
return data.size() + 2;
}
// Now define getItemViewType of your own.
#Override
public int getItemViewType(int position) {
if (position == 0) {
// This is where we'll add the header.
return HEADER_VIEW;
} else if (position == data.size() + 1) {
// This is where we'll add a footer.
return FOOTER_VIEW;
}
return super.getItemViewType(position);
}
// So you're done with adding a footer and its action on onClick.
// Now set the default ViewHolder for NormalViewHolder
public class ViewHolder extends RecyclerView.ViewHolder {
// Define elements of a row here
public ViewHolder(View itemView) {
super(itemView);
// Find view by ID and initialize here
}
public void bindView(int position) {
// bindView() method to implement actions
}
}
}
Now let us define the layouts one by one. Here is the list_item_normal.xml.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/normal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="This is a text to be displayed in each item in the RecyclerView"
android:textSize="16sp"
android:textStyle="normal" />
</LinearLayout>
And the list_item_footer.xml should look like the following.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:orientation="vertical">
<RadioGroup
android:id="#+id/myRadioGroup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="10dp"
android:checkedButton="#+id/sound">
<RadioButton
android:id="#+id/sound"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Sound" />
<RadioButton
android:id="#+id/vibration"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Vibration" />
<RadioButton
android:id="#+id/silent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Silent" />
</RadioGroup>
<EditText
android:id="#+id/notes"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Notes" />
<LinearLayout
android:id="#+id/buttons"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="10dp">
<TextView
android:id="#+id/cancel_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="Cancel" />
<TextView
android:id="#+id/submit_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="Submit" />
</LinearLayout>
</LinearLayout>
Finally, the list_item_header.xml should have the following.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/sub_headline_literal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="10dp"
android:text="Some long texts having a long size so that it takes multiple lines in the view to replicate the real-life app use case. This is important to have 3-4 lines this textview so that we can see if the views are being populated correctly. Hope this sentence is long enough to replicate the real-life scenario of this TextView content. Thank you."
android:textSize="16sp"
android:textStyle="normal" />
</LinearLayout>
Now you have divided the components of your original layout into parts. Hence the main layout should look like the following.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/headline_literal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:gravity="center"
android:padding="10dp"
android:text="Heading"
android:textSize="20sp"
android:textStyle="bold" />
<View
android:id="#+id/divider"
android:layout_width="fill_parent"
android:layout_height="2dp"
android:layout_marginTop="5dp"
android:background="#c0c0c0" />
<android.support.v7.widget.RecyclerView
android:id="#+id/dummy_rv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:padding="10dp" />
</LinearLayout>
Hence, I am sharing one sample Activity to run this code which will show the overall implementation.
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
private RecyclerView mRecyclerView;
private ArrayList<String> data = new ArrayList<String>();
private RecyclerViewWithHeaderFooterAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initializeData();
initializeRecyclerView();
}
private void initializeRecyclerView() {
mRecyclerView = findViewById(R.id.dummy_rv);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
adapter = new RecyclerViewWithHeaderFooterAdapter(this, data);
mRecyclerView.setAdapter(adapter);
}
private void initializeData() {
for (int i = 0; i < 10; i++) data.add("Position :" + i);
}
}
Hope that helps!

Customize Recycler view to set maxHeight.
public class MaxHeightRecyclerView extends RecyclerView {
private int mMaxHeight;
public MaxHeightRecyclerView(Context context) {
super(context);
}
public MaxHeightRecyclerView(Context context, AttributeSet attrs) {
super(context, attrs);
initialize(context, attrs);
}
public MaxHeightRecyclerView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
initialize(context, attrs);
}
private void initialize(Context context, AttributeSet attrs) {
TypedArray arr = context.obtainStyledAttributes(attrs, R.styleable.MaxHeightScrollView);
mMaxHeight = arr.getLayoutDimension(R.styleable.MaxHeightScrollView_maxHeight, mMaxHeight);
arr.recycle();
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (mMaxHeight > 0) {
heightMeasureSpec = MeasureSpec.makeMeasureSpec(mMaxHeight, MeasureSpec.AT_MOST);
}
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
n attrs.xml
<declare-styleable name="MaxHeightScrollView">
<attr name="maxHeight" format="dimension" />
</declare-styleable>
set RecyclerView height wrap_content in xml and maxHeight to fixwidth in dp.
The RecyclerView will consume height wrap_content till fixWidth which you set, after reaching to maxHeight, the RecyclerView will scrollable.

If you also need to limit the size of your NestedScrollView by makeing a custom NestedScrollView:
public class CustomNestedScrollView extends NestedScrollView {
private int maxHeight;
private final int defaultHeight = 200;
public CustomNestedScrollView(Context context) {
super(context);
}
public CustomNestedScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
if (!isInEditMode()) {
init(context, attrs);
}
}
public CustomNestedScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
if (!isInEditMode()) {
init(context, attrs);
}
}
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
public CustomNestedScrollView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
if (!isInEditMode()) {
init(context, attrs);
}
}
private void init(Context context, AttributeSet attrs) {
if (attrs != null) {
TypedArray styledAttrs = context.obtainStyledAttributes(attrs, R.styleable.CustomNestedScrollView);
//200 is a defualt value
maxHeight = styledAttrs.getDimensionPixelSize(R.styleable.CustomNestedScrollView_maxHeight, defaultHeight);
styledAttrs.recycle();
}
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
heightMeasureSpec = MeasureSpec.makeMeasureSpec(maxHeight, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
attr.xml
<declare-styleable name="CustomNestedScrollView">
<attr name="maxHeight" format="dimension" />
</declare-styleable>
example layout for custom NestedScrollView:
<your.package.CustomNestedScrollView
android:layout_weight="1"
app:maxHeight="90dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<!--Child view with RecyclerView here-->
</your.package.CustomNestedScrollView>
Along with this custom NestedScrollView if you apply the customization of your RecyclerView then it will work exactly how you want. I hope this helps!

Android: onItemClick and onItemLongClick do not respond

My Android app is composed of an SQLite database which populates individual ListView items with data user saves. Those items are available for display in activity_main.xml.
I have a class called RecordsListFragment which contains the two problematic methods: onItemClick and onItemLongClick. Here is the class in its entirety:

I haven't found a definite answer to my question, so I'm asking for a bit of help here.

You need set OnItemClickListener and OnLongItemClickListener to ListView, I edited your method in the initializing variable ListView:
private void findViewsById(View view) {
recordsListView = (ListView) view.findViewById(R.id.list_records);
recordsListView.setOnItemClickListener(this);
recordsListView.setOnItemLongClickListener(this);
}

Change your code in
#Override
public CardViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = (LayoutInflater) parent.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.R.layout.client_info_fragment_revision_layout, parent, false);
CardViewHolder holder = new CardViewHolder (view);
}

It's just for debug purpose:
If you are using Android studio then open your R.java under folder
build->generated->source->r->debug->yourpackagename->R.java
Then search 0x7f0d00aa in the file; It will be like
public static final int TextView01=0x7f0d00aa;
Search the corresponding ID in xml files under resources folder. Then check the XML content syntax,naming,source etc.
