Android, LinearLayout won't scroll

Question

I am relatively new to android programing. Can anybody tell me why my ScrollView won't scroll?

My activity has implemented OnGestureListener for getting some touch information. But, I tried to disable onGestureListener and it still won't work.

It works outside of the SlidingDrawer. Is it possible to get it work inside of the SlidingDrawer?

I solved it by giving to ScrollView ID and then put that ID in SlidingDrawer android:content="@+id/content".

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="right"
        android:background="@drawable/pozadina_touchpad"
        android:orientation="vertical" >

        <LinearLayout
            android:layout_width="100dp"
            android:layout_height="match_parent"
            android:layout_gravity="right"
            android:orientation="vertical" >

            <SlidingDrawer
                android:id="@+id/prosirenje"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="horizontal"
                android:content="@+id/content"
                android:handle="@+id/handle" >

                <Button

                    android:background="@drawable/gumb_slider"
                     />

                <ScrollView

Answer 1

give some value to scrollView's width and height and try like this

<ScrollView
    android:id="@id/content"
    android:layout_width="300dp"
    android:layout_height="300dp"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="15dp">
    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >
    </LinearLayout>
</ScrollView>

please change scrollview id like this:

android:id="@id/content"

please change handle button id like this:

android:id="@id/handle"
