Content going behind Navigation Bar

I am facing a problem with android 5.0 and above. Whenever I align any view to parent bottom, Content is getting hidden behind the soft navigation button.

Here is the example screen

Above attached is the screenshot of the screen generated after creating new project from Android Studio 1.5. I just added an edit text at the bottom of the fragment.

as you can see, half of the edit text is behind the navigation bar.

Though codes are auto generated by Android Studio, I am still posting the codes below.

P.S. If removing or replacing the drawable is part of your solution, then I have already tried it. And I couldnt find any proper solution in Android guidelines too.

Any solution here? I have a similar issue...Iciness
@Iciness problem is with scroll flags of toolbar. It pushes the UI down to pull it up while scrolling toolbar. You can turn it off to make the UI niormal.Preternatural

android:fitsSystemWindows="true"

This worked for me. The view no longer overlaps with soft navigation.

I don't have a off-the-shelve solution, but this might be of help. The activity_main.xml root element states it should fit the system window: android:fitsSystemWindows="true".

I guess you'll have to find a way to detect whether the bottom navbar is on screen, and if true, add extra margin-bottom to your activity layout.

That tag doesn't make any difference, It re size the screen whenever keyboard pops up.Preternatural

android:fitsSystemWindows="true" did not solve on my layout. I had to add respective attributes to the partially hidden top and bottom views.

android:paddingTop="?android:attr/actionBarSize" android:paddingBottom="?android:attr/actionBarSize"

E.g on top:

<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:id="@+id/myid"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        android:paddingTop="?android:attr/actionBarSize">

This work around is not efficient. May be you need to debug a bit more to figure out why that flag did not work for you.Preternatural
