GridView filling parent despite wrap_content

Question

I have a gridlayout like this in the main layout xml of my activity:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:id="@+id/parentLayout"
    android:layout_gravity="right">

    <GridView 
        android:id="@+id/gridview"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:background="#AAAAAA"
        android:columnWidth="90dp"
        android:numColumns="3"
        android:verticalSpacing="10dp"
        android:horizontalSpacing="10dp"
        android:stretchMode="none"
        />

</LinearLayout>

I populate it with 6 icons by inflating the following:

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

What I want is that the gridlayout is right aligned in the linear layout and that it just wraps its content. I am testing this by giving it a different coloured background. The layout_height="wrap_content" works fine, but the width seems to have no effect. The result is this:

Screenshot of wrap_content not working as I expect

Any ideas?

Thanks in advance, Stephen

use android:gravity="right" in LinearLayout instead-of LinearLayout ..............

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

    android:gravity="right"> //<-----------------------

android:gravity sets the gravity of the content of the View its used on.
android:layout_gravity sets the gravity of the View or Layout in its parent.

for test try

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

    android:gravity="right">

    <TextView android:id="@+id/gridview" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:background="#AAAAAA"
        android:text="ewewqe" />

</LinearLayout>

also see this not the answer but see

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal"
    android:id="@+id/parentLayout"
    android:layout_gravity="right"
    android:gravity="right" android:weightSum="1">

    <GridView
        android:id="@+id/gridview"
        android:layout_height="wrap_content"
        android:layout_width="0dp"
        android:background="#AAAAAA"
        android:columnWidth="90dp"
        android:numColumns="3"
        android:verticalSpacing="10dp"
        android:horizontalSpacing="10dp"
        android:stretchMode="none"
        android:layout_weight=".5" />

</LinearLayout>

Last two lines are from [this answer](http://stackoverflow.com/a/3482757/379693) :) – Paresh Mayani Jun 23 '12 at 12:33
yes these are just to make the thing clear .....answer is above that... I confirmed because after seeing your answer I was in doubt...... as you set android:gravity="right" in GridView – Dheeresh Singh Jun 23 '12 at 12:37
Makes no difference. The right align is one part, but I am more concerned about getting the GridView to actually wrap the contents width. – steprobe Jun 23 '12 at 12:43
please make it clear first, so now grid goes to right or not? – Dheeresh Singh Jun 23 '12 at 12:51
I tried the same code for Textview instead of grid and that is working – Dheeresh Singh Jun 23 '12 at 12:54
I am sure it works for you with a textview, but it doesn't help me with the GridView unfortunately. – steprobe Jun 23 '12 at 13:02

ohh please update android:layout_weight=".5" in new sample code – Dheeresh Singh Jun 23 '12 at 13:12
My question was how to wrap the content in the grid view, not how to get it to take 50% of the screen. – steprobe Jun 23 '12 at 13:17
I know that, I already said that this in not a solution.... but looks width should be there other wise it will take parent width – Dheeresh Singh Jun 23 '12 at 13:37

I tried various combinations of gravity and none of them worked. The problem seems to be that the width of the content, from the perspective of the LinearLayout is full screen. – steprobe Jun 23 '12 at 12:43
