How to show a snakbar with Lottie animation in start from a recycler view adapter

I am making a chat app and I want to add a feature like telegram to copy links ,phone numbers and etc.. from long clicking on an auto link.I used this library to add long click listeners on a auto link.I implemented it successfully.But when I do this, i want to show a Lottie animation in the start like this but on long click of a link.
I tried many answer but I get an exception.I already made the layout for custom snakbar.It is given below
<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="56dp"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_margin="#dimen/_3sdp"
android:backgroundTint="#color/snakbar_background"
app:cardCornerRadius="#dimen/_4sdp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical">
<com.airbnb.lottie.LottieAnimationView
android:id="#+id/lottieSnakbar"
android:layout_width="35dp"
android:layout_height="35dp"
android:layout_marginStart="#dimen/_5sdp"
android:layout_marginEnd="#dimen/_10sdp"
app:lottie_rawRes="#drawable/copy"
app:lottie_autoPlay="true"
app:lottie_loop="false"/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="Text copied to clipboard"
android:gravity="center_vertical"
android:theme="?snackbarTextViewStyle"
tools:ignore="HardcodedText" />
</LinearLayout>
</androidx.cardview.widget.CardView>
Now how can I achieve this?

You can use an interface in the adapter. And receive and show snakbar from activity

You could use localBroadcast and broadcast a local signal from the adapter and let the other Activity(probably receiver) handle snakbar.
AdapterClass{
LocalBroadcastManager localBroadcastManager = null;
void sendB(parms){
if(localBroadcastManager != null){
localBroadcastManager.sendBroadcast(Intent("NOTIFICATION_RECEIVER"))
}
onCreateViewHolder(){
localBroadcastManager = LocalBroadcastManager.getInstance(applicationContext)
}
onBindViewHolder(){
if(someCondition){
sendB(parms);
}
}
then receive it from an activity then call snakBar

How to show a notification icon in android studio

I am building an android application where I am letting the users to sign in using google also. When they sign in using google and do not register themselves using the registration page then there are certain information which are left out.I also have a screen which updates the profile information of the user.
I want to set an icon on the home screen(kind of a bell icon) which displays that there are some notification and when the user click on that the button it tells that some information are left to be added and it redirects them to the update profile page.
The icon I want is like the notification icon(bell) in youtube.
Is there any way I can do this?

}
Note: I am not using any custom toolbar, neither am I using any toolbar, my theme for the application is: NoActionBar

There are three ways to get that notification icon depending upon the theme you are using in your Activity.
1. No.ActionBar Theme: If you're not using any ActionBar or toolbar in your activity then you can create a View(ImageView or Button) in your Activity's layout file with Height and Width as same as the notification icon which is around 28dp and then position it at the top right corner of the screen. You can change the background image of the view according to the state you want.
2. Create your own toolbar: You can create your own toolbar and set the menu item in it. While creating the menu item make sure that you select showAsAction="always" this way your icon is always visible. here is a link for the reference
3.ActionBar Theme: If you're using the action bar theme then you can create a menu file with one item like in Option 2 and then override the onCreateOptionsMenu and inflate then inflate your menu in it.

Notification notification = new Notification.Builder(this)
.setContentTitle(title)
.setContentText(text)
.setSmallIcon(R.drawable.ic_notification)
.setContentIntent(pIntent)
.setDefaults(Notification.DEFAULT_SOUND|Notification.DEFAULT_LIGHTS|Notification.DEFAULT_VIBRATE)
.setAutoCancel(true)
.build();

BottomAppBar raises while using soft keyboard

I'm trying to hide BottomAppBar behind keyboard but when I change focus to another EditText the part of BottomAppBar start to appear like in photo . Also I have already tried change windowSoftInputMode but I really need adjustPan.
<com.google.android.material.bottomappbar.BottomAppBar
android:id="#+id/bottom_appbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
app:backgroundTint="#color/colorAccent"
app:fabCradleMargin="#dimen/fab_margin"
app:fabCradleRoundedCornerRadius="#dimen/fab_corner_radius"
app:hideOnScroll="false"
app:layout_scrollFlags="scroll|enterAlways"
android:transitionName="bottom_appbar"
style="#style/Widget.MaterialComponents.BottomAppBar" />
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/bottom_fab"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:clickable="true"
app:tint="#color/colorPrimary"
android:tint="#color/colorPrimary"
app:backgroundTint="#color/floatButtonColor"
app:rippleColor="#color/colorAccent"
app:layout_anchor="#id/bottom_appbar"/>

try adding this to your <activity> tag in the manifest
android:windowSoftInputMode="adjustPan|stateHidden"

How to fix the layout in OnConfigurationChanged when i do not want the activity to restart

So i fixed my activity restart on changing orientation (i needed to do that for client requirement) but now i am having issues fixing the display layouts.I have tried a lot of combinations of layout_height and layout_weight but failed.
I just need some guidance in how to fix this.
My layout xml:

The relevant code which i use in onConfigurationChanged:
RelativeLayout.LayoutParams params = (android.widget.RelativeLayout.LayoutParams) new RelativeLayout.LayoutParams(
android.widget.RelativeLayout.LayoutParams.MATCH_PARENT,
android.widget.RelativeLayout.LayoutParams.MATCH_PARENT);
scrollView.setLayoutParams(params);
sessionView.setLayoutParams(new FrameLayout.LayoutParams(android.widget.FrameLayout.LayoutParams.MATCH_PARENT,
android.widget.FrameLayout.LayoutParams.MATCH_PARENT, Gravity.CENTER));
scrollView.requestLayout();
sessionView.requestLayout();
Screenshot when initially in Portrait:
Screenshot when in landscape:
thanks.

Try this
LayoutParams p = scrollView.getLayoutParams();
LayoutParams p1 = sessionView.getLayoutParams();
DisplayMetrics outMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(outMetrics);
p.width = outMetrics.widthPixels;
p.height = outMetrics.heightPixels
p1.width = outMetrics.widthPixels;
p1.height = outMetrics.heightPixels

your view may be filling the screen with fill_parent. But the portrait aspect ratio image will not fit in as background in landscape layout.
use a different image of landscape width and height and use it in drawable-land folder (name of the image should be same)
image from drawable-land will be automatically picked for landscape layout

findViewById Returns An Error

findViewById gives out an error, I think it's because it's returning null. My app is forced to close.
SensorManager sensorManager=null;
TextView x= null;
TextView y= null;
TextView z= null;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
setContentView(R.layout.main);
x= (TextView) findViewById(R.id.tv1);
y= (TextView) findViewById(R.id.tv2);
z= (TextView) findViewById(R.id.tv3);
}
XML:
<TextView
android:id="#+id/tv1"
android:layout_x="10px"
android:layout_y="550px"
android:text="#string/x"
/>
<TextView
android:id="#+id/tv2"
android:layout_x="100px"
android:layout_y="550px"
android:text="#string/y"
/>
<TextView
android:id="#+id/tv3"
android:layout_x="200px"
android:layout_y="550px"
android:text="#string/z"
/>
Can someone please tell me what I'm doing wrong?
SOLVED!
I used the XML given by Sunny at the bottom! Thank you to all!

That's simple.... tv* is not in your layout!
Please post the layout, I am 100% sure it doesn't contain:
<TextView android:id="#+id/tv1"/>
<TextView android:id="#+id/tv2"/>
<TextView android:id="#+id/tv3"/>
Please also learn how to get a logcat before going further in android development! ;-)
Window -> Show View -> Logcat

yes above code working fine and xml file should be like this.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="#+id/tv1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<TextView
android:id="#+id/tv2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<TextView>
android:id="#+id/tv3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
</LinearLayout>

yes that problem and if with xml is not done then
You import android.R;
so that it will give error if xml you have
remove that
and import PACKAGENAME.R;

First : Verify that your TextView Are present on your layout : main.xml :
<TextView android:id="#+id/tv1" .../>
<TextView android:id="#+id/tv2" .../>
<TextView android:id="#+id/tv3" .../>
Second : reBuild your project by following this steps : Project ==> Clean ==> Select your project and click OK .

The reason why this happens is :
findViewById() will search for the TextViews in the View hierarchy established by setContentView(R.layout.main). So if the TextViews aren't in main.xml you will get a null
