Simple Grouping in Android ListView (title with picture)

Idea: Add a simpleadapter,simpleadapter in the ListView to dynamically add headlines and headings under the headline, followed by ideas.

First step: Create a ListView layout file List.xml

1<linearlayout xmlns:android= "Http://schemas.android.com/apk/res/android"2Xmlns:tools= "Http://schemas.android.com/tools"3Android:layout_width= "Match_parent"4android:layout_height= "Match_parent"5android:orientation= "Horizontal"6Tools:context= ". Mainactivity ">7<ListView8Android:id= "@+id/list"9Android:layout_width= "Fill_parent"Tenandroid:layout_height= "Wrap_content" > One</ListView> A</LinearLayout>

Step two: Build the List_items_menu.xml layout file

<?xml version= "1.0" encoding= "Utf-8"? ><relativelayout xmlns:android= "Http://schemas.android.com/apk/res/android"Android:id= "@+id/relativelayout01"Android:layout_width= "Fill_parent"Android:layout_height= "Wrap_content"Android:paddingbottom= "4SP"Android:paddingleft= "12SP"Android:paddingright= "12SP" > <LinearLayout android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"android:orientation= "Vertical" > <TextView Android:id= "@+id/itemtitle"Android:layout_width= "Wrap_content"Android:layout_height= "Match_parent"android:layout_gravity= "Left"Android:layout_marginbottom= "4DP"Android:layout_margintop= "7DP"Android:text= "title"/> </LinearLayout> <LinearLayout android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"android:orientation= "Horizontal" > <ImageView Android:id= "@+id/itemimage"Android:layout_width= "40SP"Android:layout_height= "40sp"/> <TextView Android:id= "@+id/xiaoitemtitle"Android:layout_width= "Fill_parent"Android:layout_height= "Wrap_content"Android:text= "Small title"android:textsize= "15sp"/> </LinearLayout></RelativeLayout>

Step three: Building activity classes

 PackageCom.example.test_menu;Importjava.util.ArrayList;ImportJava.util.HashMap;ImportCom.example.test_menu. R;Importandroid.app.Activity;ImportAndroid.content.Context;ImportAndroid.os.Bundle;ImportAndroid.view.LayoutInflater;ImportAndroid.view.View;ImportAndroid.view.Window;ImportAndroid.view.WindowManager;ImportAndroid.view.ViewGroup.LayoutParams;ImportAndroid.widget.AdapterView;ImportAndroid.widget.ListView;Importandroid.widget.RelativeLayout;ImportAndroid.widget.SimpleAdapter;ImportAndroid.widget.TextView;ImportAndroid.widget.AdapterView.OnItemClickListener;ImportAndroid.widget.Toast; Public  classTestextendsActivity {ArrayListListItem; HashMap<string, object>map;    Simpleadapter Listitemadapter;    ListView list; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate); //The Settings screen has no title         This. Requestwindowfeature (Window.feature_no_title); //Remove title bar         This. GetWindow (). SetFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLS        Creen);                        Setcontentview (r.layout.list); //bind the ListView inside the layoutList =(ListView) Findviewbyid (r.id.list); //generating dynamic arrays, adding dataListItem =NewArraylist(); String[] a={"Pipe network dynamic", "Construction daily", "notice announcement"}; String[] B={"Operation Management", "Operation Monitoring", "Path simulation optimization", "material Move Job", "Valve switch Management"}; String[] C={"Patrol Management", "Inspection Plan", "Patrol Record", "Patrol monitoring"}; String[] D={"Special Management", "Field station management", "Pipeline management", "Pipe Gallery Management", "Valve management"}; //icon in front of a small title        int[] Image_a={R.drawable.ic_launcher,r.drawable.lcmn,r.drawable.lct,r.drawable.ic_launcher};        Map (a,image_a);        Map (b,image_a);        Map (c,image_a);         Map (d,image_a); Listitemadapter=NewSimpleadapter ( This, ListItem,//Data SourceR.layout.list_items_menu,//XML implementation of ListItem//the children of the dynamic array corresponding to the Imageitem                NewString[] {"Itemtitle", "Itemimage", "Xiaoitemtitle" },                //a Imageview,textview ID in the imageitem XML file                New int[] {r.id.itemtitle,r.id.itemimage, r.id.xiaoitemtitle}); //Add and showList.setadapter (Listitemadapter); //Add Menu clickList.setonitemclicklistener (NewOnitemclicklistener () {@Override Public voidOnitemclick (adapterview<?> arg0, View arg1,intArg2,LongArg3) {                 for(inti = 0; I < listitem.size (); i++) {                                    if(Arg2 = =i) {Toast.maketext (Getapplicationcontext (), Listitem.get (ARG2). Get ("Xiaoitemtitle") + "" +arg2, Toast.length_short). Show ();            }                }            }        }); }     Public voidMap (string[] A,int[] Image) {             for(inti=0;i<a.length;i++) {Map=NewHashmap<string, object>();  for(intj=0;j<image.length;j++){                                if(i==0) {Map.put ("Itemtitle", a[0]); }Else if(i== (j+1) {map.put ("Itemimage", Image[j]);//ID of the image resourceMap.put ("Xiaoitemtitle", A[i]);        }} listitem.add (map); }            }      }

The effect is as follows:
