This example shows custom Grid View, have a ImageView and TextView in each grid like this:
1) Create a folder /res/drawable to hold the different pictures.
2) Modify main.xml to have a GridView :
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" Now,
3) Implement mygrid.xml in folder /res/layout/, it's the layout of individual grid.
Next,
4) Modify the main Java code in src/<Packge-Name>/mygridActivity.java.
1) Create a folder /res/drawable to hold the different pictures.
2) Modify main.xml to have a GridView :
<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:id="@+id/gridView1"
android:layout_height="fill_parent"
android:horizontalSpacing="5px"
android:verticalSpacing="5px"
android:stretchMode="columnWidth"
android:columnWidth="60px"
android:numColumns="3"
android:gravity="center"
/>3) Implement mygrid.xml in folder /res/layout/, it's the layout of individual grid.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical">
<ImageView
android:layout_height="100px"
android:id="@+id/imageView1"
android:layout_width="100px"
android:background="#444444"></ImageView>
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:textStyle="bold"
android:layout_gravity="center"
android:textColor="#669966"></TextView>
</LinearLayout>
4) Modify the main Java code in src/<Packge-Name>/mygridActivity.java.
