<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

        android:layout_alignParentBottom="true"
        android:layout_below="@+id/image"

            android:padding="5dp"
            android:text="please God forgive me for all my mistakes i have ever done in my life please God forgive me for all my mistakes i have ever"
            android:textAppearance="?android:attr/textAppearanceSmall"
            android:textColor="#ffffff"

            />

    </ScrollView>
</RelativeLayout>

this is my xml file and scrollview is not scrolling.

Can anyone please suggest a solution?

I am using a custom view for a listview using a custom adapter

Answer 1

It is not recommended to use multiple Scrollable view inside one another. You are using ScrollView inside List View and that you should not do. It is a bad practice.

Instead you use Dynamic Layout Addition via view.add()

Answer 2

Height of your scroll view is 200dp. Since 200dp fits in the screen there is nothing to scroll. You can try setting the height to

android:layout_height="match_parent"

or

android:layout_height="wrap_content"

if height of your UI items are larger then screen size.
