Layout Params not working in Custom Dialog Fragment

I am trying to set my custom dialog fragment to use the full width of the screen. The one solution is to set LayoutParams on view. But they are not working.
Things I Tried
Changing parent Layout
using getLayoutParams().getClass() which returns null
Layout Validator shows correct layout so no prob here, here is my Layout
<?xml version="1.0" encoding="utf-8"?>

Here is my DialogFragment class
public class AdLoadFragment extends DialogFragment {

#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
AskHintDialogBinding binding=AskHintDialogBinding.inflate(inflater,container,false);
View view=binding.getRoot();
return view;
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
MyUtilsApp.showLog(String.valueOf(view.getClass()));
view.setLayoutParams(new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,
FrameLayout.LayoutParams.MATCH_PARENT));
}
}

Recyclerview doesn't show or scroll in fragment

I have found some questions regarding this issue here but none of them helped to solve my problem. Recycler view works fine but there is issue in lollipop version. It works perfectly in an activity but doesn't show or scroll when used inside fragment. My fragment screen appears blank but the tap listeners in recycler view's adapter is working. When I migrated my fragment code to an activity, it worked fine. I am using 28.0.0 Here is my xml code.

God Damn! After being stuck in this issue for 2 whole days, I finally found the solution. It was because I was using FragmentTransaction.TRANSIT_FRAGMENT_FADE when adding fragment inside activity. Removing the transition solved my problem

Fragment is not appearing on the hosting activity

I am adding a fragment to an activity as shown below in the code. but at run time i found that the fragment is never shown.
i examined the fragment layout and the its viewgroup in the main layout.
please let me know why it is not showing.

The reason that it is not showing it is because in your onCreate method, you have not done setContentView and that is why it is empty and not showing.
Add the following line:
setContentView(R.layout.mainLayout);
This should allow the fragment to be shown.

I used this way and it worked with me
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v=inflater.inflate(R.layout.fragment_1_layout, container, false);
return v;}

I want current layout to be changed so that I can scroll entire layout.

Now, I set layout for title on the top. Then, a Imageview, a textview and a listview follow below this layout, and only 1 textview is inside listview.
listview can vary in size.
The problem is, if the size of the listview is very big, I can only scroll the screen assigned to listview.
But, I want scroll the entire screen.
To solve this problem, I added scrollview outside of the first linearlayout.
However, It didn't work.(the imageview disappeared)
What can I do?

you can make your listview addheaderview,and put your imageview and textview into headerview

DialogFragment with transparent background

I'm trying to create a fullscreen (but status bar has to still be visible) Dialog with custom transparent (same as this answer https://stackoverflow.com/a/29482234), but my background is not transparent.
I've wasted 2 days trying all solution, but it just won't work. My goal is to show a dialog with custom dim color (instead of default black). The answer above looked like what I needed but I can't get it to work. Any suggestions?
My code:
<style name="CustomDialogTheme2" parent="#android:style/Theme.Dialog">
<item name="android:windowIsFloating">false</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
