Question

I am trying to display a GridView in a Dialog. Despite all my efforts, the GridView width grows to the entire screen, instead of wrapping to the columns. The layout and an image depicting the issue are below (I set a background color for the GridView to illustrate the issue).

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/colorgridview"
    android:background="#FF00CCBB"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:numColumns="4"
    android:verticalSpacing="5dp"
    android:horizontalSpacing="5dp"
    android:columnWidth="70dp"
    android:stretchMode="none"
/>

I know that this post is a bit outdated. But if someone needs a solution to this, this answer may come in handy.

It is possible to set the view’s width after screen measurement.

To do this:

Let your class implement the OnGlobalLayoutListener.
The screen is measured when the onGlobalLayout method is called. We can do our magic here.
GridView.getLayoutParams().width = ….

edit:
I wasn’t very clear on how to add the onGlobalLayoutListener. See plugmind’s post, he shows how to add it.
Can't figure out how to get view/layout width/height

Kind regards,
