Recently encountered a need to dynamically add pictures in the ListView display ad

Using Horizontalscrollview to add on a ListView

Java code:

Package Com.baozi.bzhorizontalscrollview;import Java.util.arraylist;import Android.app.activity;import Android.content.intent;import Android.net.uri;import Android.os.bundle;import Android.text.TextUtils;import Android.view.layoutinflater;import Android.view.view;import Android.view.view.onclicklistener;import Android.widget.arrayadapter;import Android.widget.imageview;import Android.widget.linearlayout;import Android.widget.listview;public class Mainactivity extends Activity {private ListView lv;private View headerview;private LinearLayout Header_ll; arraylist<string> ArrayList = new arraylist<string> (), @Overrideprotected void OnCreate (Bundle Savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (r.layout.activity_main); LV = (ListView) Findviewbyid (r.id.lv); Headerview = Layoutinflater.from (this). Inflate (R.layout.item_home_header, null); Header_ll = ( LinearLayout) Headerview.findviewbyid (R.ID.HEADER_LL); for (int i = 0; i <; i++) {View Coupon_home_ad_item = Layoutinflater.from (This). Inflate (R.layout.home_item, null); ImageView icon = (ImageView) coupon_home_ad_ Item.findviewbyid (R.ID.COUPON_AD_IV);//Take this line of icon to set the picture final String href = "HTTP://WWW.BLOG.CSDN.NET/AAAWQQQ"; Textutils.isempty (href)) {Coupon_home_ad_item.setonclicklistener (new Onclicklistener () {// The Click event for each item is added here @overridepublic void OnClick (View v) {uri uri = uri.parse (href); Intent Intent = new Intent (intent.action_v Iew,uri); startactivity (intent);});} Header_ll.addview (Coupon_home_ad_item);} Lv.addheaderview (Headerview);//The header is added to the//ListView test data for (int i = 0; i <) through the Addheaderview method of the ListView 20; i++) {Arraylist.add (i + "-------------" + System.currenttimemillis ());} Arrayadapter adapter = new Arrayadapter (this, r.layout.item,r.id.textview1, arrayList); Lv.setadapter (adapter);}}

XML code:

Activity_main.xml

<relativelayout xmlns:android= "http://schemas.android.com/apk/res/android"    xmlns:tools= "http// Schemas.android.com/tools "    android:layout_width=" match_parent "    android:layout_height=" Match_parent "    android:background= "#f4f4f4"    android:paddingbottom= "@dimen/activity_vertical_margin"    android: paddingleft= "@dimen/activity_horizontal_margin"    android:paddingright= "@dimen/activity_horizontal_margin"    android:paddingtop= "@dimen/activity_vertical_margin"    tools:context= " Com.baozi.bzhorizontalscrollview.MainActivity ">    <listview        android:id=" @+id/lv "        android: Layout_width= "Fill_parent"        android:layout_height= "fill_parent" >    </listview></ Relativelayout>

Item_home_header.xml

<?xml version= "1.0" encoding= "UTF-8"? >

Home_item.xml
<?xml version= "1.0" encoding= "UTF-8"? ><framelayout xmlns:android= "http://schemas.android.com/apk/res/ Android "xmlns:ptr=" Http://schemas.android.com/apk/res-auto "android:id=" @+id/coupon_home_ad_ll "Android:layout_w Idth= "Wrap_content" android:layout_height= "wrap_content" android:layout_marginbottom= "10DP" Android:layout_margin left= "5DP" android:layout_marginright= "5DP" android:layout_margintop= "10DP" android:gravity= "center" android:o        rientation= "Horizontal" > <imageview android:id= "@+id/coupon_ad_iv" android:layout_width= "120DP"        android:layout_height= "90DP" android:layout_margin= "4DP" android:background= "@drawable/ic_launcher" Android:scaletype= "Centercrop"/> <textview android:layout_width= "Wrap_content" Android:layout_        height= "wrap_content" android:layout_gravity= "center" android:text= "Point Me" android:textcolor= "#000000" Android:textsize= "20sp"/>   <view android:layout_width= "1DP" android:layout_height= "90DP" android:background= "#000000"/&gt ;</framelayout>


Steps:
Load Header First
Headerview = Layoutinflater.from (this). Inflate (r.layout.  Item_home_header,null);
header_ll = (linearlayout) Headerview. Findviewbyid (r.id.  Header_ll);

Get the LinearLayout inside the header

ImageView the server gets through the For loop add to LinearLayout on the header
Add Click events, etc.

Please correct me for the shortcomings.
