Add many CardViews with onclick method programmatically

I'm still new to the Android and I want to add a CardView to the activity each time a button is clicked. The CardView has text on it and a background image. I already have the XML file that can add this, but because I want to be able to add more than one, I can't use <include.>. The first image is when the button is clicked once and the second is when the button is clicked 3 times. I already have the onClick for the TextView that says "Click To Add Block" and the XML for the CardView, but I can't make it so that you can add them and change the text in the TextView in each and every one of them. I also can't seem to find a way to programmatically add an onClick listener to the programmatically created CardView. Later down the line, I would also like to be able to delete the CardView from a click of a button too.
Here is the CardView XML file (Before it was inside a Relative Layout)
<androidx.cardview.widget.CardView
android:id="#+id/cardviewClassesBlock1"
android:layout_width="330dp"
android:layout_height="75dp"
android:layout_marginTop="90dp"
android:layout_centerHorizontal="true"
app:cardCornerRadius="10dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/ic_launcher_background">
<TextView
android:id="#+id/textviewClassesBlock1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="10dp"
android:layout_marginTop="3dp"
android:textSize="22sp"
android:fontFamily="#font/amiko_semibold"
android:textColor="#color/white"
android:text="Block A"/>
<ImageView
android:layout_width="60dp"
android:layout_height="6dp"
android:layout_marginStart="10dp"
android:layout_below="#+id/textviewClassesBlock1"
android:background="#drawable/rounded_corner_edittext" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:layout_marginEnd="5dp"
android:textColor="#color/white"
android:text="P - 0 | T - 0 | A - 0"/>
</RelativeLayout>
</androidx.cardview.widget.CardView>

I have created a sample project for You.
First You have to create a layout for Your CardView. In res/layout create card_base.xml. In this layout add:
<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/cardviewClassesBlock1"
android:layout_width="wrap_content"
android:layout_height="75dp"
android:layout_centerHorizontal="true"
app:cardCornerRadius="10dp"
android:layout_margin="10dp"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/ic_launcher_background"
>
<TextView
android:id="#+id/textviewClassesBlock1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="10dp"
android:layout_marginTop="3dp"
android:text="Block A"
android:textSize="22sp"
/>
<ImageView
android:layout_width="60dp"
android:layout_height="6dp"
android:layout_below="#+id/textviewClassesBlock1"
android:layout_marginStart="10dp"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentBottom="true"
android:layout_marginEnd="5dp"
android:text="P - 0 | T - 0 | A - 0"
/>
</RelativeLayout>
</androidx.cardview.widget.CardView>
This is basically Your CardView with small changes.
Next, in Your activity_main.xml add this:
<?xml version="1.0" encoding="utf-8"?>
<androidx.appcompat.widget.LinearLayoutCompat xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity"
>
<Button
android:id="#+id/butAdd"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Add New Card"
/>
<Button
android:id="#+id/butDoSth"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Do something"
/>
<androidx.appcompat.widget.LinearLayoutCompat
android:id="#+id/cards"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<include
android:id="#+id/includedLayoutFirst"
layout="#layout/card_base"
/>
</androidx.appcompat.widget.LinearLayoutCompat>
</androidx.appcompat.widget.LinearLayoutCompat>
This is a starter (very simple) look of Your app. It has one button and one CardView which is already inserted.
Now in Your MainActivity.java paste this:
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.LinearLayoutCompat;
import androidx.cardview.widget.CardView;
public class MainActivity extends AppCompatActivity
{
private int starter = 66; //ASCII code for `B`
LinearLayoutCompat cards;
Button buttonAdd;
Button buttonDoSth;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
cards = findViewById(R.id.cards);
buttonAdd = findViewById(R.id.butAdd);
buttonDoSth = findViewById(R.id.butDoSth);
buttonAdd.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
CardView newCard = new CardView(MainActivity.this);
getLayoutInflater().inflate(R.layout.card_base, newCard);
TextView t = newCard.findViewById(R.id.textviewClassesBlock1);
String current = Character.toString((char) starter++);
t.setText("Block " + current);
newCard.setTag(current); //
cards.addView(newCard);
}
});
buttonDoSth.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
findBlockAndDoSomething("B");
}
});
}
private void findBlockAndDoSomething(String name)
{
Log.d("MyTAG", "CLICK");
for (int i = 0; i < cards.getChildCount(); i++)
{
CardView selected = (CardView) cards.getChildAt(i);
if (selected.getTag() != null && selected.getTag().toString().equals(name))
{
// do something. E.g change block name
TextView textViewClassesBlock1 = selected.findViewById(R.id.textviewClassesBlock1);
textViewClassesBlock1.setText("Block XXX");
return;
}
}
}
}
Result (starter code and with adding new CardView):

Input of symbols in EditText

There's an EditText in fragment. User should input a number here (format of input is numeric). But there's a problem: nothing is shown in editText. User can input, but doesn't see the number. What's the matter?
Xml of fragment:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

nHeight = Integer.parseInt(eHeight.getText().toString());
if (nWeight-nHeight<100) {
textView.setText("Normal weight");
}
}
});
return v;
}
}
UPDATE
styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

</resources>
Actually I think that emulator can cause this problem, because when I input numbers, I can change the position of cursor, that's why there's something here. But it's not shown. But at the same time when I try to parse to int information from this editTexts, it cause an error as there's nothing here.

I have tested the codes you've provided, there was a problem with the layout. Just add this line to your EditText xml block: android:layout_height="wrap_content" instead of hard fixing it to 20dp, which is not considered as a good dimension of height for EditText field.
As per Google Android developer suggestions, the minimum height for an EditText should be 50dp. So you may also consider changing the height of EditText to 50dp also instead of "wrap_content"
Thus the modified xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

Link CheckBox with Checkable Interface for a ListView

For my Android application I have implemented a ListView that is populated by a Custom Adapter from BaseAdapter and a custom Layout for the rows.
Now i would like to make entries checkable by using the corresponding methods from ListView, like setItemChecked() or getCheckedItemCount().
I created a custom Layout class for the row layout that imlpements Checkable interface and retrieved the Button using findViewById to be able to access it inside the overridden methods from Checkable.
When long clicking on an entry in the list, the methods get invoked, but I get a NullpointerException, saying the CheckBox is referencing null:
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.CompoundButton.setChecked(boolean)' on a null object reference
What is the appropriate way to link the checkbox of each entry inside a checkable Layout?
The checkable Layout class looks like this:
package com.lastname.name.arcadaobjecttracker;
import android.content.Context;
import android.support.annotation.Nullable;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.CheckBox;
import android.widget.Checkable;
import android.widget.LinearLayout;
//extend the Layout for the row view (each element in the listView) to add support for checkable rows (called by the listView methods like setItemChecked() etc.)
public class CheckableRowLayout extends LinearLayout implements Checkable
{
View view;
CheckBox checkBox;
public CheckableRowLayout(Context context)
{
super(context);
init(context);
}
public CheckableRowLayout(Context context, #Nullable AttributeSet attrs)
{
super(context, attrs);
init(context);
}
public CheckableRowLayout(Context context, #Nullable AttributeSet attrs, int defStyleAttr)
{
super(context, attrs, defStyleAttr);
init(context);
}
private void init(Context context)
{
checkBox = (CheckBox) findViewById(R.id.checkBox);
}
#Override
public void setChecked(boolean checked)
{
checkBox.setChecked(checked);
}
#Override
public boolean isChecked()
{
return checkBox.isChecked();
}
#Override
public void toggle()
{
checkBox.toggle();
}
}
The Layout consists of the following xml file with checkbox:
<?xml version="1.0" encoding="utf-8"?>
<com.lastname.name.arcadaobjecttracker.CheckableRowLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"

Scrollview is not scrolling in AbsoluteLayout

I'm trying to make an Activity which allows the user to press a button and when he presses it, it generates an EditText and a spinner. The problem is that the scroll view does not scroll. The page stays as is.
XML:
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_order_items"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.example.nir.nestleapp.OrderItemsActivity">
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentStart="true">
<AbsoluteLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:layout_width="70dp"
android:layout_height="40dp"
android:layout_y="58dp"
android:inputType="phone"
android:ems="10"
android:id="#+id/Quantity"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:hint="quantity"
android:layout_x="11dp" />
<Spinner
android:layout_width="174dp"
android:layout_height="48dp"
android:layout_x="148dp"
android:layout_y="58dp"
android:id="#+id/ItemSpinner" />
</AbsoluteLayout>
</ScrollView>
<Button
android:text="add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_x="133dp"
android:layout_y="431dp"
android:id="#+id/Generate" />
</AbsoluteLayout>
Java:
package com.example.nir.nestleapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AbsListView;
import android.widget.AbsoluteLayout;
import android.widget.Button;
import android.widget.EditText;
import android.widget.RelativeLayout;
import android.widget.Spinner;
public class OrderItemsActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_order_items);
final AbsoluteLayout layout = (AbsoluteLayout) findViewById(R.id.activity_order_items);
final Spinner Items=(Spinner)findViewById(R.id.ItemSpinner);
final Button Generate=(Button)findViewById(R.id.Generate);
final EditText Quantity=(EditText)findViewById(R.id.Quantity);
final float[] yPlacement = {280};
Generate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Spinner GeneratedSpinner=new Spinner(OrderItemsActivity.this);
EditText GeneratedQuantity=new EditText(OrderItemsActivity.this);
layout.addView(GeneratedSpinner);
GeneratedSpinner.setX(Items.getX());
yPlacement[0] =yPlacement[0]+200;
GeneratedSpinner.setY(yPlacement[0]);
layout.addView(GeneratedQuantity);
GeneratedQuantity.setX(Quantity.getX());
GeneratedQuantity.setY(yPlacement[0]);
GeneratedQuantity.setHint("quantity");
GeneratedQuantity.setWidth(300);
}
});
}

You can change your Absolute layout, use as child LinearLayout
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentStart="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:layout_width="70dp"
android:layout_height="40dp"
android:layout_y="58dp"
android:inputType="phone"
android:ems="10"
android:id="#+id/Quantity"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:hint="quantity"
android:layout_x="11dp" />
<Spinner
android:layout_width="174dp"
android:layout_height="48dp"
android:layout_x="148dp"
android:layout_y="58dp"
android:id="#+id/ItemSpinner" />
</LinearLayout>
</ScrollView>

Changing AbsoluteLayout into a LinearLayout is the best way to get rid from this issue.

You can't use a Spinner or an EditText in a Widget. That's because every Widget layout must be based on RemoteViews. Following every layout that is supported:
Layout classes
FrameLayout
LinearLayout
RelativeLayout
GridLayout
Widget classes
AnalogClock
Button
Chronometer
ImageButton
ImageView
ProgressBar
TextView
ViewFlipper
ListView
GridView
StackView
AdapterViewFlipper
Read more about it in the Docs.

The problem is your layout contains an EditText which is not supported by widgets on Android.
For a complete list of views you may use see: http://developer.android.com/guide/topics/appwidgets/
