I am facing two issue here.
1. If I create HorizontalScrollView and add custom view using
HorizontalScrollView.addview() the application did not crash but
my custom view is not display. It onDraw never gets called.
2. In other approach if I use XML and specify my custom view as child
of HorizontalScrollView then the application crashes.
And I could not figure out how to provide agrument if to custom
view constructor when using XML approach.
Regards,
Yasir

You need to make the view that is a child of the scroll view actually
larger in size than the scroll view so there is something to scroll.
Further questions on this would best be asked on android-developers or
StackOverflow.

I have a custom view derived from View class. Where I am drawing a

horizontally bigger then screen.
I want to make is scrollable horizontally. The custom take sevaral
argument it it constructor. I tried various option
Like make layout xml and
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<HorizontalScrollView android:id="@+id/scroll"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">
<com.yasir.canvasTest.GraphView
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</HorizontalScrollView >
</LinearLayout>
then
in onCreate of Activity
setContentView(R.layout.horscroll);
Question :- How will I specify argument to the contructor of my
custom view.
I also tried creating HorizontalScrollView and adding custom view
using HorizontalScrollView.addview() the application did not crash but
my custom view is not display. It onDraw never gets called.
Please suggest me how to solve this issue.
