Android: ScrollView is not scrolling

Question

I am trying to create a layout with a header, a banner below it, and then a couple of ListView under the banner. I want the the complete screen to be scrollable except the header. Now I know that ListView does not scroll within a ScrollView so I have set the height of the ListView big enough to show all the items. The problem is that, even after these changes, I see that the ListView is scrolling independently and the complete screen is not scrollable.

Answer 1

Change height of scroll view from match_parent to wrap_content. Because scroll view only enable scrolling if its total height is more than the height of parent view. i.e. replace

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

with this code:

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fillViewport="true">

I've used the following method several times on several apps. I use a special subclass of ListView:

package com.yourcompany.appname.views;

import android.content.Context;
import android.util.AttributeSet;
import android.view.ViewGroup;
import android.widget.ListView;

public class NonScrollableListView extends ListView {
    public NonScrollableListView(Context context) {
        super(context);
    }

    public NonScrollableListView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public NonScrollableListView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int heightMeasureSpec_custom = MeasureSpec.makeMeasureSpec(
                Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
        ViewGroup.LayoutParams params = getLayoutParams();
        params.height = getMeasuredHeight();
    }
}

Then in your layout, instead of using 's, use something like this:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">
    <com.yourcompany.appname.views.NonScrollableListView
        android:id="@+id/listId"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />
</LinearLayout>

Hope this helps!
