Dyanamically adding RemoteViews in custom notification in for loop, issue in setting pendingintent

I am creating a custom notification and adding buttons dynamically using this code:

RemoteViews remoteViews = new RemoteViews(this.getPackageName(), R.layout.custom_notification);

for (int i = 0; i < 100; i++) {

Intent mybuttonsIntent = new Intent(this, NotifyActivityHandler.class);
RemoteViews rv = new RemoteViews(this.getPackageName(), R.layout.button_layout);
Bundle b = new Bundle();
b.putInt("abcd", i);
mybuttonsIntent.putExtras(b);
rv.setOnClickPendingIntent(R.id.button, PendingIntent.getActivity(this, 0, mybuttonsIntent, PendingIntent.FLAG_UPDATE_CURRENT));
remoteViews.addView(R.id.rlMainNotification, rv);
}
Intent intent = new Intent(this, MainActivity.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentIntent(pIntent)
.setContent(remoteViews);
NotificationManager notificationmanager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
notificationmanager.notify(0, builder.build());


Here's button_layout.xml:

<Button xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:id="@+id/button"
android:layout_height="wrap_content"
android:layout_weight="1" />


In NotifyActivityHandler, I am using this code to get Int:

Bundle extras = getIntent().getExtras();
if (extras != null) {
int level = extras.getInt("abcd");
Toast.makeText(this, "testing" + level, Toast.LENGTH_LONG).show();


But the problem is that every button passes the same Int i.e 99
If instead of using R.id.button I use rv.getLayoutId() then the buttons do not respond. I want that every button should pass the value assigned to it respectively in the for loop.

Edit: on request of a commenter, here's the xml of custom_notification

<?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="match_parent"
android:weightSum="10">

<LinearLayout
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent">

<ImageView
android:id="@+id/autoIcon"
android:tint="@color/themeColor"
android:layout_gravity="center"
android:scaleType="fitCenter"
android:src="@drawable/ic_brightness_medium_white_48dp"
android:layout_width="wrap_content"
android:layout_height="match_parent"/>
</LinearLayout>

<LinearLayout
android:id="@+id/rlMainNotification"
android:layout_width="0dp"
android:gravity="center_vertical"
android:layout_gravity="center_vertical"
android:orientation="horizontal"
android:layout_height="match_parent"
android:paddingRight="4dp"
android:paddingLeft="2dp"
android:layout_weight="9"
>

</LinearLayout>

</LinearLayout>

Answer

change this line to:

  rv.setOnClickPendingIntent(R.id.button, PendingIntent.getActivity(this, 0, mybuttonsIntent, PendingIntent.FLAG_UPDATE_CURRENT));

to

  rv.setOnClickPendingIntent(R.id.button, PendingIntent.getActivity(this, i, mybuttonsIntent, PendingIntent.FLAG_UPDATE_CURRENT));

basically change 0 to i.
