Answer 1

Add android:fillViewport in your ScrollView.

<ScrollView     
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/scrollviewdb"     
    android:fillViewport="true"
    android:layout_width="match_parent"    
    android:layout_height="wrap_content" >  
    <LinearLayout    
      xmlns:android="http://schemas.android.com/apk/res/android" 
      android:orientation="vertical"    
      android:layout_width="match_parent"    
      android:layout_height="wrap_content">    
         <TextView        
            android:layout_width="match_parent"   
            android:layout_height="wrap_content"         
            android:textSize="15sp"  
            android:padding="5dp"     
            android:id="@+id/ghavaed_text"/> 
    </LinearLayout>
</ScrollView>

As @Ironman explained, The reason behind this is ScrollView would become useless if its content was always as tall as itself. To work around this, you need to use the ScrollView attribute called android:fillViewport. When set to true, this attribute causes the scroll view’s child to expand to the height of the ScrollView if needed. When the child is taller than the ScrollView, the attribute has no effect

Answer 2

I faced the same issue and solved it by adding :android:layout_gravity="top" to the LinearLayout inside the ScrollView.

Answer 3

You can add marginBottoom with minus value on scrollview.

Also in my case, I found that the background height takes more space on the bottom. solution: I have moved the background from the relative layout to the scroll view and it has been solved this problem.

<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"
tools:context=".MainActivity"
android:fillViewport="true"
android:background="@drawable/bg" //i move this background here from realative 
    layout
android:overScrollMode="never"
>
 <RelativeLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
  </RelativeLayout>
  </ScrollView>

hope this solves your problem
