Resize AlertDialog to fit image exactly

Related searches

I have the following AlertDialog with an image inside it:

As you can see there is a small gap just above and just below the image. I'd like to remove that gap.

My layout xml looks like:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/alert_thumb_root"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content" >

  <ImageView android:id="@+id/thumb"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content" />
</LinearLayout>

Unless you create the whole dialog by your self, it's really difficult to control those kind of things. However, if you don't mind resizing the image, you could try something like:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/alert_thumb_root"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content" >

  <ImageView android:id="@+id/thumb"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:scaleType="fitXY"/>
</LinearLayout>

  • It works but like you said it does resize the image. I can't understand why Android just doesn't make it the same size as the image... what's the reason for making it bigger?
  • I'm facing the same challenge. Have you perhaps found an answer?
  • +1 Thank you ! Helped me with a similar issue, that android:scaleType="fitXY" worked, in combination with wrap_content when rendering a bitmap to a custom Dialog.
