Implementation of Android jiugongge

1. xml code:

Copy codeThe Code is as follows: <? Xml version = "1.0" encoding = "UTF-8"?>
<LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android"
Android: orientation = "vertical"
Android: layout_width = "fill_parent"
Android: layout_height = "fill_parent"
Android: layout_weight = "1.0"
Android: background = "@ drawable/yellow"
>
<ImageView android: id = "@ + id/ImageView01"
Android: layout_width = "100sp"
Android: layout_height = "100sp"
Android: layout_gravity = "center_vertical"
Android: background = "@ drawable/a"> </ImageView>
<GridView
Android: id = "@ + id/gridview"
Android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"
Android: numColumns = "3"
Android: verticalSpacing = "30dip"
Android: horizontalSpacing = "10dip"
Android: columnWidth = "90dip"
Android: stretchMode = "columnWidth"
Android: gravity = "center"
Android: listSelector = "@ drawable/c"
>
</GridView>
</LinearLayout>

Android: numColumns = "3" indicates automatic when the number of columns in the nine cells is auto_fit.

2. Implementation Code

Copy codeThe Code is as follows: public class MainActivity extends Activity {

/** Called when the activity is first created .*/

@ Override
Protected void onCreate (Bundle savedInstanceState ){
// TODO Auto-generated method stub
Super. onCreate (savedInstanceState );
// Set no screen title
This. requestWindowFeature (Window. FEATURE_NO_TITLE );
// Remove the title bar
This. getWindow (). setFlags (WindowManager. LayoutParams. FLAG_FULLSCREEN,
WindowManager. LayoutParams. FLAG_FULLSCREEN );
SetContentView (R. layout. activity_main );

GridView gridview = (GridView) findViewById (R. id. gridview );
// Create an array list object
ArrayList <HashMap <String, Object> lstImageItem = new ArrayList <HashMap <String, Object> ();

/**
* Add content for each grid
*/
For (int I = 1; I <10; I ++ ){
HashMap <String, Object> map = new HashMap <String, Object> (); // create a hashmap Object

If (I = 1 ){
Map. put ("ItemImage", R. drawable. g11 );

LstImageItem. add (map );
}

/**

){
HashMap <String, Object> item = (HashMap <String, Object>) arg0
. GetItemAtPosition (arg2 );
If (item. get ("ItemText"). equals (
