Why my GridView cuts off at The End?

Why my GridView cuts off at The End? - java

In the above picture, the item at the bottom is cut off like a red arrow.
Perhaps the size of the Gridview is the entire screen, and NavigationBottomView seems to cover part of the GridView. I want to specify the height of the GridView from the top of the screen to the top of the BottomNavigationView.
Below is my xml code.
1> Home screen xml code with NavigationBottomView(home.xml)

//switching fragment
if (fragment != null) {
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.fragment_container, fragment).commit();
return true;
}
return false;
}
}
I would be grateful if you could read the questions I have made and give them some advice.

Its happening because you have set the FrameLayout height 520dp in xml
set the frameLayout height match and also use android:layout_above="#+id/navigation"
try this code
<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:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/navigation"
android:orientation="horizontal">
<OtherViews.../>
</FrameLayout>
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="?android:attr/windowBackground"
app:menu="#menu/navigation">
</android.support.design.widget.BottomNavigationView>
</RelativeLayout>

Cannot see widgets in tab layout in android studio

I am facing the problem of cannot see widgets in tab layouts. I have created textview and button in Overview Fragment but I cannot see them when run code. Is it right to initialize textviews and buttons in oncreateview() of fragment which we don't want to transfer to another tab. I have searched a lot about my problem but cannot get any hint. Code is given below:

How to avoid the softkeyboard overlapping the EditText in fragment?

I try both methods addling line android:windowSoftInputMode="adjustPan" in manifest or adding getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);on Fragment onCreateView but still facing the same issue.

How do i reset a Card Stack or get the Previous Card?

So, I have followed this tutorial (https://www.youtube.com/watch?v=cS5l_hPwC10) on how to do a card stack and it works fine even with 2 cardstacks at the same time. now I want to add a button so i can reset both stacks and/or a button to get to the previous card
Here is all the code I have related to the card stack. Tell me if you need more since this is the first time I am trying to programm something

}

Just keep handles to CardStack instead:
private CardStack cardStack01;
private CardStack cardStack02;
And let the Fragment implement getters and setters for these.

I wanna have same fab transformation behavior as shown in
Material Website in Full Screen (or morph) section.

For the FabTransformationSheetBehavior to work, you need to change the isExpanded value.
on change of this value, expand and collapse animation will be called and visibility of the linearlayout and fab button will be handled automatically. Don't change visibility manually as this would block transformation animation.
Use back button to transform back to FAB.
val fab: FloatingActionButton = findViewById<FloatingActionButton>(R.id.fab)
fab.setOnClickListener { fab.isExpanded = !fab.isExpanded } // this sets isExpanded as true
val back = findViewById<ImageButton>(R.id.back)
back.setOnClickListener{ fab.isExpanded = !fab.isExpanded } // this sets isExpanded as false
