I created a custom layout where I have a couple of LinearLayout in a ScrollView. Problem is when I set my layout in setContentView() to my custom layout (when the application starts), the emulator gives an error and force closes! I don't know why. I have tried with another custom layout or set it to main and it seems to work fine.

Any ideas what could be wrong?


Yes, I meant to say the app is crashing. Here is the xml code for the custom layout: (too many spinners!)

<?xml version="1.0" encoding="utf-8"?>

The problem is that you're specifying a view without including a required attribute (layout_width).

<View android:layout_height="5dp"/>

It's up to you to define the expected behavior for width, but here's one example that will fix your problem:

<View android:layout_height="5dp" layout_width="fill_parent" />

The Android developer documentation indicates these fields are required (source: http://developer.android.com/guide/topics/resources/layout-resource.html).
