Android - scrolling ScrollView in Fragment is impossible

Question

I have a Fragment in ViewPager which can be scrolled right and left. But every has ScollView with TextView. This TextView can have a lot of text (code-generated), so I want to be able to scroll it vertically, but if I toutch the device, fragments are more important, so I can only swipe it horizontally. Is any way to fix it? my layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:id="@+id/colectionday_relative_main"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#123456"
    android:orientation="vertical"
    tools:context="${relativePackage}.${activityClass}" >

    <RelativeLayout
        android:id="@+id/colectionday_relative_top"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/rounded_layout_top" >

        <TextView

What do you mean by "Fragment can be scrolled right and left"? Is the `Fragment` inside a `ViewPager`? — PPartisan, Nov 07 '15 at 19:06
It's possible the `ViewPager` is intercepting all swipe events in that case. You could test this by creating your own `ViewPager` class, overriding `onInterceptTouchEvent()`/`onTouchEvent()` and see what happens with up and down swipes. I'll test it myself when I get the chance. — PPartisan, Nov 07 '15 at 19:28
@PPartisan it isn't thuth, in another place I have viewpager that contains fragment, every of them contains gridview, and this can be simply scrolled vertically, either viewpager can be horizontally. Problem isn't occurring — Andret2344, Nov 07 '15 at 20:08
It's happen in all devices snd SDK's? what wrap the fragment itself? — blay, Feb 16 '16 at 09:28

try this code if run rewrite some parameters for your own.

<ScrollView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/scrollView2"
            android:scrollIndicators="right">

            <FrameLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:paddingRight="8dp">

                <FrameLayout
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:paddingTop="20dp"
                    android:scrollIndicators="right">


                <FrameLayout>

                </FrameLayout>

            </FrameLayout>
        </ScrollView>

edit :

you must modify scrollview height. wrap_content -> match_parent and you can add this attributes

android:focusable="true"
android:focusableInTouchMode="true"
android:descendantFocusability="beforeDescendants"

edit2:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:id="@+id/colectionday_relative_main"
android:layout_width="match_parent"
android:layout_height="match_parent" // edit
android:focusable="true" // add
android:focusableInTouchMode="true" // add
android:descendantFocusability="beforeDescendants" // add
android:orientation="vertical"
tools:context="${relativePackage}.${activityClass}" >

// ... 

</LinearLayout>

`fragmentScrollView` means object of class that extends Fragment, FragmentAdapter of just ViewPager object? And `childScrollView` is this scrollview that I want to scroll? – Andret2344 Nov 07 '15 at 19:26
your root element of layout is LinearLayout – LEETAEJUN Nov 07 '15 at 19:45
Again - nothing has changed. – Andret2344 Nov 07 '15 at 20:01
what is "android:layout_above="@+id/colectionday_button_share" ? show all layout code – LEETAEJUN Nov 07 '15 at 20:12
I've added it, look up. – Andret2344 Nov 07 '15 at 20:19
