Use This 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.oss.myapplication.MainActivity">

    <ScrollView
        android:id="@+id/src"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:layout_editor_absoluteX="8dp"
        tools:layout_editor_absoluteY="8dp">

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

            <RelativeLayout
                android:id="@+id/layout"
                android:layout_width="match_parent"
                android:layout_height="0dp">

            </RelativeLayout>

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="bottom"
                android:orientation="vertical"
                android:layout_below="@+id/layout">

                <TextView
                    android:id="@+id/textView"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_weight="1"
                    android:text="@string/content" />
            </LinearLayout>

        </RelativeLayout>

    </ScrollView>

</RelativeLayout>

You have to remove android:layout_gravity="bottom".

To get to the bottom of your ScrollView, add android:id="@+id/scrollView" to your ScrollView xml tag and simply add the below code to your onCreate function or any other place where you need it after you've set the text.

final ScrollView scrollView = ((ScrollView) findViewById(R.id.scrollView));
        scrollView.postDelayed(new Runnable() {
            @Override
            public void run() {
                scrollView.fullScroll(ScrollView.FOCUS_DOWN);
            }
        },100);

You can try to use post() instead of postDelayed() like this:

final ScrollView scrollView = ((ScrollView) findViewById(R.id.scrollView));
        scrollView.post(new Runnable() {
            @Override
            public void run() {
                scrollView.fullScroll(ScrollView.FOCUS_DOWN);
            }
        });

It does not have a delay, but this can lead to problems in some circumstances.

See this 

ScrollView scr = (ScrollView) findViewById(R.id.scr);
scr.setNestedScrollingEnabled(true);
