Scroll not working if activity is full screen

Question

I have a login screen with scroll view and I'm setting the layout the full screen like so

if (VERSION.SDK_INT >= 21) {
        getWindow().setStatusBarColor(Color.TRANSPARENT);
        getWindow().getDecorView().setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}

The problem is I'm not able to scroll when the keyboard pops up even though I have a scroll view. Here's my layout

<ScrollView
android:id="@+id/scrollView"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/ooru"
android:fitsSystemWindows="false"
tools:context=".android.LoginActivity">


<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <ImageView
        android:id="@+id/branding_login"
        android:layout_width="170dp"
        android:layout_height="35dp"
        android:layout_centerHorizontal="true"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="55dp"
        android:scaleType="centerInside"
        android:src="@drawable/branding"/>

    <ImageView
        android:id="@+id/logged_in_icon"
        android:layout_width="54dp"
        android:layout_height="54dp"
        android:layout_below="@id/branding_login"
        android:layout_centerHorizontal="true"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="42dp"
        android:scaleType="centerCrop"
        android:src="@drawable/ic_fan_icon"/>

    .... //More views

</RelativeLayout>

</ScrollView>

I tried searching about the problem and some suggested adding android:windowSoftInputMode="adjustResize", it doesn't work for me.

P.S: The parent theme for this activity is Theme.AppCompat.Light.NoActionBar

add "android:fillViewport="true" " to your scroll view and set relative layout height as match_parent — Sachchidanand, Jun 07 '16 at 12:27

Setting fillViewPort and adding match_parent did not work, and @SunilSharma I had already tried doing it as shown in that answer — Shashank Udupa, Jun 07 '16 at 12:32
If problem is in above lollipop then try `android:fitsSystemWindows="true"` — Sunil Sharma, Jun 07 '16 at 12:36
Did that as well, actually I tried removing View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN) flag, the scroll works fine then, but it will show the status bar and that's not what I want — Shashank Udupa, Jun 07 '16 at 12:38
If nothing is working then try using view tree observer and scrollY parameter in scrollview — Sunil Sharma, Jun 07 '16 at 12:55

Try

1. Add KeyboardUtil class to your code.

2. Add following line to onCreate method of activity

new KeyboardUtil(this, contentView) //inflate layout and assign it to contentView object

KeyboardUtil.java

The main problem is that you set the screen to fullscreen mode.

View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN

if you set fullscreen as

View.SYSTEM_UI_FLAG_FULLSCREEN

with

android:windowSoftInputMode="adjustResize".

However, one problem is that it will show up actionbar.

the layout you made is not perfect, we need scroll there, where view is large and your view is two small and not perfect that's why isn't scrolling,you can hide you keyboard when login launch and on edit ext click keyboard will show. – rachna Oct 23 '19 at 12:27

For those who came here expecting a solution.

If you want a login screen without SupportActionBar, hide it dynamically, no need for FullScreen theme.

@Override
protected void onCreate(Bundle savedInstanceState){ 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_yours);
    if (getSupportActionBar() != null)
        getSupportAction().hide();

    ...
        your onCreate code here
    ...
}

Hope it helps.
