BringToFront of the custom view inside a coordinator layout - android

Actually there is already similar question
BringToFront doesn't work inside a coordinator layout
However no of suggestions helped me to make bringToFront work within a coordinatorlayout.
Here is the layout-xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="#layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/main_content_container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<fragment
android:id="#+id/navigation_drawer_container"
android:name="..."
android:layout_width="#dimen/navigation_drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"/>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/..."
android:clickable="true"
android:layout_gravity="bottom|end"
android:layout_marginRight="20dp"
android:layout_marginBottom="60dp"
app:borderWidth="0dp"/>
<CustomView
android:id="#+id/customview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentBottom="true"
android:orientation="vertical"
android:visibility="gone"
app:layout_behavior="..."/>
</android.support.design.widget.CoordinatorLayout>
The custom view is inherited from FrameLayout. It can change its height.
To bring the custom view to the front first I tried to add:
mCustomView.bringToFront();
Then
mCustomView.requestLayout();
mCustomView.invalidate();
Finally also
((View)mCustomView.getParent()).requestLayout();
But without success. The button is still on the top.
Did I missed anything?
Maybe there other possibilities to bring the custom view to front or to put the button under custom view?
I also tried to add a behaviour to the button, but since it's visibility depends not only on the custom view I thrown this approach away.
Thank you for any help in advance.

I finally found a workaround - if I set setEnabled(false) on the AppBar, it goes to the background and I can draw other stuff over it regardless of API level.

Why does picture-in-picture show invisible content?

I have something very strange:
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<DrawerLayout
android:id="#+id/rootLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/frameLayoutRoot"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:baselineAligned="false"
android:orientation="vertical"
android:visibility="invisible"
android:layout_margin="10dp">
<fragment
android:id="#+id/fooFragment"
android:name="net.mydomain.android.FooFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</FrameLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigationView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end"
android:fitsSystemWindows="false"
app:itemBackground="#drawable/layout_background"
app:menu="#menu/activity_single_view" />
</DrawerLayout>
</layout>
Please note android:visibility="invisible" of FrameLayout. The normal screen is exactly as expected - nothing shows:
However, picture-in-picture shows the following:
It shows the content (the fragment) outside of FrameLayout that is supposed to be invisible.
Could anyone shed some light on this?
The picture-in-picture is done by following the official guideline. Nothing special.
[Edit] 2019-08-26:
I added
android:layout_margin="10dp"
to the invisible FrameLayout. The result is exactly the same. This means the gray box is the root layout.

how to navigation bar at the bottom

I have tied using this code..
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="?android:attr/windowBackground" />
//parent views are Relative Layout then ScrollView
It is moving with the scrolling of the screen but I want navigation bar to be fixed, even after scrolling the screen, any can help me ??
Just like the Messenger app, I want it to be fixed!
-you can use following code or something like that....
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
</RelativeLayout>
</ScrollView>
<com.google.android.material.bottomnavigation.BottomNavigationView
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
<android.support.design.widget.BottomNavigationView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="?android:attr/windowBackground"/>
I got it! It's fixed and not affecting with scrolling root layout is Relative Layout.
Thanks for your help Mr Amit Ghoswani

Scrollview doesnt work with framelayout

I have an activity layout that includes my fragment container this way,
<include
layout="#layout/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/background_container" />
and my fragment container is compose of linearlayout and a framelayout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/transparent"
android:padding="10dp">
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/transparent" />
</LinearLayout>
The problem is that I have to add my scrollable fragment in this container but the scroll doesnt seem to work. My layout goes like this
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
...
...
</LinearLayout>
</ScrollView>
I have tried several answer like
Using NestedScrollView
Adding minimum height to framelayout
Using fillViewport="true"
etc.
But nothing seems to work. Any idea what I've been doing wrong? Any help would be appreciated. Thanks in advance! Cheers!
Edit:
My activity layout contains navigation drawer, i dont know if it matter. And i add the view using
ft.replace(R.id.fragment_container, myFragment).commit();
i also dont know if fragment replace messes with my view. Please help. Thanks
it seems my fragment container's LinearLayout is missing orientation and also frameLayout
android:layout_height should be match_parent
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/transparent"
android:orientation="vertical" // orientation
android:padding="10dp">
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" // match_parent
android:background="#android:color/transparent" />
</LinearLayout>

RecyclerView is not working in NestedScrollView

I am using NestedScrollView in tab layout and when I implemented RecyclerView in NestedScrollView 2 problems occur:
Toolbar is not hiding.
RecyclerView in not scrolling smoothly.
Here is my Code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:fillViewport="true"
xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout
android:layout_width="match_parent"
android:background="#fff"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:layout_below="#+id/toolbar"
android:id="#+id/recyclerView"
android:background="#fafafa"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
<ProgressBar
android:id="#+id/progressBar1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
</RelativeLayout>
</android.support.v4.widget.NestedScrollView>
use recylerView.setNestedScrollingEnabled(false); to make your scrolling smoother.
Create separate layout files for views and try. And include those into the list view.
<LinuearLayout ..>
<include layout="#layout/cv1"/>
<include layout="#layout/rv1"/>
<include layout="#layout/rv2"/>
<include layout="#layout/rv3"/>
</LinearLayout>
This is just a clue to you. I did solve similar issues long back in past. Please try experimenting with this clue.

Two scroll views for two-sided navigation drawer hides toggle

I have spent a lot of hours trying to find the problem with ActionBarDrawerToggle, but the problem is in my main layout.
Let me show what the problem is.
Here is example, how it looks like initally after application start.
As you can see hamburger is present but not shown right now.
Than if swipe drawer menu it appears.
It looks as it should look like, but it can disappear suddenly, when for example invalidateOptionsMenu() was called.
So I have tried to find the problem with toggle, but it is in my layout
Here is my layout xml file.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/navigation_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linear_layout_main_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_main"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:visibility="gone"
app:theme="#style/MainAppTheme.ToolbarMain"
app:titleTextAppearance="#style/MainAppTheme.Toolbar.Title" />
</LinearLayout>
<ViewStub
android:id="#+id/stub_progress_bar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:inflatedId="#+id/progress_bar_buttons"
android:layout="#layout/view_stub_progressbar_bg" />
</FrameLayout>
<ScrollView
android:id="#+id/frame_layout_drawer_left"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fillViewport="true">
</ScrollView>
<ScrollView
android:id="#+id/frame_layout_drawer_right"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_gravity="end"
android:fillViewport="true" />
</android.support.v4.widget.DrawerLayout>
The problem is in the last ScrollView, without last/right scroll view everything works fine. By the way this layout works fine with two drawers, but only hamburger is missed in this case.
I guess the problem is that navigation drawer toogle conflicts with two navgiation drawer view.
Because it doesn't matter what kind of view is with gravity end, it will not show hamburger in this case (if view with gravity end is present)
Please help to solve this problem, cause I have no idea how to deal with it, I need two drawers anyway.
Any help will be highly appreciated, thanks.
This is a pretty interesting issue but I think I have a solution. Well 2 solutions,
Have you creating a Frame Layout that houses two separate android.support.v4.widget.DrawerLayout layouts?
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.DrawerLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--your content -->
<ScrollView
android:id="#+id/frame_layout_drawer_left"
android:layout_width="0dp"
android:layout_height="match_parent"/>
</android.support.v4.widget.DrawerLayout>
<android.support.v4.widget.DrawerLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:id="#+id/frame_layout_drawer_right"
android:layout_width="0dp"
android:layout_height="match_parent"/>
</android.support.v4.widget.DrawerLayout>
</FrameLayout>
the imbed the second drawer layout inside of the root
android.support.v4.widget.DrawerLayout.
sample xml
<android.support.v4.widget.DrawerLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--your content -->
<ScrollView
android:id="#+id/frame_layout_drawer_left"
android:layout_width="0dp"
android:layout_height="match_parent"/>
<android.support.v4.widget.DrawerLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:id="#+id/frame_layout_drawer_right"
android:layout_width="0dp"
android:layout_height="match_parent"/>
</android.support.v4.widget.DrawerLayout>
</android.support.v4.widget.DrawerLayout>
