Here is my answer:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@id/linearLayout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal">
    <GridView
        android:id="@+id/gridView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:columnWidth="100dip"
        android:gravity="center"
        android:numColumns="3"
        android:stretchMode="spacingWidthUniform"
        android:verticalSpacing="10dip" />
</LinearLayout>

Don't use padding or horizontalSpacing if you don't need it as it may cause problems with other views.

Note also that fill_parent is already deprecated.

I hope this will solve your problem:

  <LinearLayout
        android:layout_gravity="center_horizontal"
        android:gravity="center"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >
    <GridLayout
        android:id="@+id/gridlayou4x3"
        android:rowCount="4"
        android:columnCount="3"
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="80"
        android:minWidth="25px"
        android:minHeight="25px" />
  </LinearLayout>

Answer 3

Issue occurred when I updated the gridview adapter from:

        gridView = inflater.inflate(R.layout.mobile, null);

to

        gridView = inflater.inflate(R.layout.mobile, parent, false);

so I just reversed back using a try catch if the old (null) version failed.

Answer 4

well, in case you are using a custom adapter thing to inflate single rowview inside your gridview then try to add android:gravity="center" to the layout of your single_row.. this will do the trick hopefully :) i.e,

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/ivClrBlock"
        android:layout_width="88dp"
        android:layout_height="88dp"
        android:layout_marginBottom="5dp"
        android:layout_marginTop="5dp"
        />

    <TextView
        android:id="@+id/tvClrName"
        android:layout_width="88dp"
        android:layout_height="wrap_content"
        android:layout_marginBottom="5dp"
        android:layout_marginTop="5dp"
        android:gravity="center"
        android:text="@string/color_name"
        android:textSize="15sp" />

</LinearLayout>

Answer 5

Here is what I did to get the items in the gridview to center (notice the stretchmode, columnwidth, gravity and horizontal and vertical spacing):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:padding="5dp" >
    <GridView
        android:id="@+id/gridview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:columnWidth="100dp"
        android:gravity="center"
        android:horizontalSpacing="10dp"
        android:numColumns="3"
        android:stretchMode="spacingWidthUniform"
        android:verticalSpacing="10dp" />
</LinearLayout>

It took me a while to figure it out, but messing with those different values I was able to get them to center.

Answer 6

Need to set the following attributes:

android:stretchMode="columnWidth"

...and...

android:gravity="center"
