Java – Android GridView spacing and centering issues

<?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:background="#FFFFFF"
    android:layout_gravity="center"
    android:padding="5dip" >
    <GridView
        android:id="@+id/homeGridView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:columnWidth="200dip"
        android:adjustViewBounds="true" 
        android:layout_gravity="center"
        android:gravity="center"
        android:horizontalSpacing="0dip"
        android:numColumns="2"
        android:stretchMode="spacingWidthUniform"
        android:verticalSpacing="10dip" />
</LinearLayout>

1. I have four icons in my GridView, but the spacing between them is
   Too much. I want to reduce it.
2. I also want the GridView to be the hub of the device, but it always is
   Stay ahead of the curve.

You should use dimensions to solve this problem.
Simply define the dimensions for each density screen.

• values-ldpi
• Value – mdpi
• HDPI value
• Value – xhdpi
• Large value

values-ldpi/dimesion.xml

<resources>
  <dimen name="grid_vertical_space">15dp</dimen>
</resources>

Value – MDPI/Dimes Ion .xml

<resources>
  <dimen name="grid_vertical_space">20dp</dimen>
</resources>

Value – hdpi/dimesion .xml

<resources>
  <dimen name="grid_vertical_space">30dp</dimen>
</resources>

Like the wise men…

Try it this way

<?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:background="#FFFFFF"
    android:layout_gravity="center"
    android:padding="5dip" >
    <GridView
        android:id="@+id/homeGridView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:columnWidth="200dip"
        android:adjustViewBounds="true" 
        android:layout_gravity="center"
        android:gravity="center"
        android:horizontalSpacing="0dip"
        android:numColumns="2"
        android:stretchMode="columnWidth"
        android:verticalSpacing="@dimen/grid_vertical_space" />
</LinearLayout>
