How to make an alert dialog fill 90% of srceen size?

Question

Hi,

I can create and display a custom alert dialog just fine but even so I have android:layout_width/height="fill_parent" in the dialog xml it is only as big as the contents.

What I want is dialog that fills the entire screen except maybe a padding of 20 pixel. Then the image that is part of the dialog would automatically stretch to the full dialog size with fill_parent.

Thanks a lot, Fabian

Set android:minWidth and android:minHeight in your custom view xml. These can force the alert not to just wrap content size. Using a view like this should do it:

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:minWidth="300dp" 
  android:minHeight="400dp">
  <ImageView
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:background="@drawable/icon"/>
</LinearLayout>
