Using GridView and Simpleadapter to implement the common nine Gongge of mobile interface

The first is two XML interfaces:

<?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:orientation="Vertical"> <GridView Android:id="@+id/mygridview"Android:layout_alignparenttop="true"Android:layout_width="wrap_content"Android:layout_height="wrap_content"Android:stretchmode="ColumnWidth"Android:numcolumns="3"/></linearlayout>

<?xml version="1.0"encoding="Utf-8"? ><linearlayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="Vertical"Android:layout_width="match_parent"Android:layout_height="match_parent"> <ImageView Android:id="@+id/itemimageview"Android:layout_width="wrap_content"Android:layout_height="wrap_content"Android:paddingleft="10DP"android:layout_gravity="Center"/> <TextView Android:id="@+id/itemtextview"Android:layout_width="fill_parent"Android:layout_height="wrap_content"android:gravity="Center"/></linearlayout>

Then the Java implementation Program:

1 Package com.example.zhoushasha.myapplication;2 3 import android.support.v7.app.AppCompatActivity;4 import Android.os.Bundle;5 import Android.view.View;6 import Android.view.Window;7 import Android.view.WindowManager;8 import Android.widget.AdapterView;9 import Android.widget.GridView;Ten import Android.widget.SimpleAdapter; One import Android.widget.Toast; A  - import java.util.ArrayList; - import Java.util.HashMap; the import java.util.List; -  -  Public classMainactivity extends Appcompatactivity { -     PrivateGridView Mgridview; +  -  +  A     Private int[] Imageres ={r.drawable.tu1, R.DRAWABLE.TU2, at R.DRAWABLE.TU3,R.DRAWABLE.TY4,R.DRAWABLE.TU5,R.DRAWABLE.TU6,R.DRAWABLE.TU7,R.DRAWABLE.TU8,R.DRAWABLE.TU9} ; -  -  -  -     PrivateString[] ItemName = {"Figure 1","Figure 2","Figure 3","Figure 4","Figure 5", -  in             "Figure 6","Figure 7","Figure 8","Figure 9"  }; -  to @Override +  -      Public voidonCreate (Bundle savedinstancestate) { the  * super.oncreate (savedinstancestate); $ Setcontentview (r.layout.activity_main);Panax Notoginseng  -  the  +Mgridview =(GridView) Findviewbyid (R.id.mygridview); A  thelistNewArraylist(); +  -         intLength =itemname.length; $  $          for(inti =0; i < length; i++) { -  -hashmap<string, object> map =NewHashmap<string, object>(); the  -Map.put ("Itemimageview", Imageres[i]);Wuyi  theMap.put ("Itemtextview", Itemname[i]); -  Wu data.add (map); -  About         } $  -         //add an adapter for Itme.xml -  -Simpleadapter Simpleadapter =NewSimpleadapter (mainactivity.
