'Scroll View not showing all the views in android

I am unable to see the top most views under ScrollView. I had placed the scrollview under Relative layout. ScrollView has a child layout i.e. Linear layout which has some series of buttons. Problem is that i am unable to see the top most views which are present in the ScrollView.

Below is the layout xml code.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

    android:orientation="vertical" >

    <RelativeLayout
        android:layout_width="fill_parent"

        <Button

Solution 2:^[2]

Just change the LinearLayout inside the ScrollView

<LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="top|center"
        android:background="#fff"
        android:orientation="vertical" >

Give the android:layout_gravity="top|center" instead of android:layout_gravity="center"

Hope it helps.

Solution 3:^[3]

This values helped me solve a similar problem: Set android:fillViewport="true" on the ScrollView and use android:gravity instead of android:layout_gravity on the ScrollView child, in my case a LinearLayout with all weights cleared.

Solution 4:^[4]

Try changing the parent layout to Linear. It might work. Don't know how and why, but for me it worked in a similar situation. Give it a try.

Solution 5:^[5]

Give a top padding of 50dp

 <LinearLayout
            android:id="@+id/linearLayout"
            android:paddingTop="50dp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" />

Solution 6:^[6]

use android:layout_gravity="center" in LinearLayout

Solution 7:^[7]

it's work 100% 

 1. LinearLayout ->
    2. ScrollView-> 

<androidx.appcompat.widget.LinearLayoutCompat
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center"
    tools:context=".sales.CustomerDetailListActivity">
       <ScrollView
            android:id="@+id/layoutCard"
            app:layout_constraintTop_toBottomOf="@+id/subtitle_of_page"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginRight="4dp"
            android:layout_marginLeft="4dp"
            android:fillViewport="false"
            android:fadingEdge="none">
