Android scrollview inside another scrollview doesn't scroll

Question

I'm trying to put a ScrollView inside another ScrollView and I tried the answers found on this site but it still doesn't seems to work completely. Here is the XML:

 <ScrollView
    android:id="@+id/scrollView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:focusableInTouchMode="false" >

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

        <TextView
            android:id="@+id/textViewDirectoryDetailName"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Name"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:textColor="@color/red" />

        <LinearLayout
            android:id="@+id/linearLayoutDirectoryDetailContainImage"
            android:layout_width="300dp"
            android:layout_height="200dp"
            android:layout_gravity="center_vertical|center_horizontal"
            android:background="@drawable/general_image"
            android:gravity="center"
            android:orientation="vertical" >
        </LinearLayout>

        <ScrollView
            android:id="@+id/scrollView2"
            android:layout_width="match_parent"
            android:layout_height="100dp"
            android:focusableInTouchMode="false" >

            <TextView
                android:id="@+id/textViewDirectoryDescription"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginTop="10dp"
                android:autoLink="phone"
                android:text="098 123 45 678"
                android:textAppearance="?android:attr/textAppearanceLarge" />
        </ScrollView>

And here is the Java code:

parentScrollView = (ScrollView) findViewById(R.id.scrollView1);
    childScrollView = (ScrollView) findViewById(R.id.scrollView2);

    parentScrollView.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View p_v, MotionEvent p_event) {
            childScrollView.getParent().requestDisallowInterceptTouchEvent(
                    false);
            // We will have to follow above for all scrollable contents
            return false;
        }
    });
    childScrollView.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View p_v, MotionEvent p_event) {
            // this will disallow the touch request for parent scroll on
            // touch of child view
            p_v.getParent().requestDisallowInterceptTouchEvent(true);
            return false;
        }
    });
    // We will have to follow above for all child scrollable contents

What seems to happen is this: when I have text in the TextView it doesn't seem to let me scroll it at all. It just scrolls the parent. But when I have no text and I touch the child ScrollView it doesn't scroll the parent so I guess it's working then. But do you have any ideas why it doesn't work when I have text?

You should use NestedScrollView.

<android.support.v4.widget.NestedScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            >
            <!-- -->
</android.support.v4.widget.NestedScrollView>
