ScrollView is not scrolling in fragment or not working properly

I'm pretty new in android and I'm developing an app but I have an error that's driving me crazy. The thing is that it doesn't scroll completely, it leaves a button out of the screen so it cant be seen. Scrollview works fine in every activity but doesn't work in tabbed activity. this code android:layout_height="match_parent" is giving problem if i change the height match-parent to 500dp or to any integer value it works fine. I want to know that why match-parent is not working.

i have tried every suggested edit to this question but still no edit works.

here is my XML file

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

The standard ScrollView need to be used as parent. I think you are using ToolBar in your activity. So in that case you can use NestedScrollView with the attribute app:layout_behavior="@string/appbar_scrolling_view_behavior"

So replace your ScrollView with:---

<NestedScrollView
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:fillViewport="true"
  app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

  {Your Child View}

</android.support.v4.widget.NestedScrollView>

You not need to take Scroll View as Root Layout not required. But you may need to add more properties to Scroll View like android:scrollbars="vertical" and android:fillViewport="true". Also you can use approach like you take Button outside of Scroll View and only scroll other content so your Button always will be visible on screen only your content will scroll.

Like 

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:background="@mipmap/ic_launcher"
    android:paddingBottom="10dp"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:paddingTop="5dp">

    <ScrollView
        android:layout_above="@+id/donate"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fillViewport="true"
        android:scrollbars="vertical">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <TextView
                android:id="@+id/name"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Welcome,"
                android:textColor="#000000"
                android:textSize="20sp" />

            <ImageView
                android:id="@+id/imageView"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentLeft="true"
                android:layout_alignParentStart="true"
                android:layout_alignParentTop="true"
                app:srcCompat="@android:drawable/ic_menu_share" />

            <TextView
                android:id="@+id/desc"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_below="@+id/imageView"
                android:gravity="center"
                android:text="Description DescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescription"
                android:textAlignment="gravity"
                android:textColor="@color/colorPrimary"
                android:textSize="17sp" />

            <TextView

                android:layout_below="@+id/desc"
                android:layout_marginTop="40dp"

        </LinearLayout>
    </ScrollView>

    <Button
        android:id="@+id/donate"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="10dp"
        android:background="@color/colorPrimary"
        android:text="I want to Donate Blood"
        android:textColor="@color/colorPrimary"
        android:textSize="18sp" />
</RelativeLayout>

Inside Fragment you can try this property android:isScrollContainer="false" inside Scroll View.

If that not work try with NestedScrollView in Fragment.

<android.support.v4.widget.NestedScrollView
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:fillViewport="true"
     app:layout_behavior="@string/appbar_scrolling_view_behavior" >


</android.support.v4.widget.NestedScrollView>

your scrollview must be the MATCHPARENT height

 <ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
