Android dynamically adds controls and implements click events for each child control

Requirements: We want to click into a shop, according to different stores, showing the sub-items of different numbers such as: disinfection room, washing room, etc... These are more or less, so you need to add them dynamically:

First, customize view (LinearLayout):

Package Cn.qust.fang.widget;import Io.vov.vitamio.mediaplayer;import Io.vov.vitamio.widget.mediacontroller;import Io.vov.vitamio.widget.videoview;import Android.app.activity;import Android.content.contentresolver;import Android.content.contentvalues;import Android.content.context;import Android.net.uri;import Android.util.attributeset;import Android.view.layoutinflater;import Android.view.view;import Android.widget.edittext;import Android.widget.linearlayout;import Android.widget.textview;import Android.widget.toast;import Cn.qust.fang.changliang.changliang;import Cn.qust.fang.db.dbmanager;import Cn.qust.fang.domain.shop;import Cn.qust.fang.main.mvplayactivity123;import Cn.qust.fang.main.r;public Class Righttopchildslayouts extends LinearLayout {shop shop=null;private TextView Text_name_sub,textview_mvurl;    View view;    MvplayActivity123 currentactivity;    /** * The disinfection between the dishes between what the * * String zi_name; /** * Video URL for disinfection between the dishes */String zi_mvurl;public RighttopchildslayOuts (context context, AttributeSet Attrs,int Defstyle) {Super (context, attrs, defstyle);//TODO auto-generated Constructor stub}//Custom Constructor public righttopchildslayouts (MvplayActivity123 context,shop shop,string zi_name,string zi_ Mvurl) {super (context); view = Layoutinflater.from (context). Inflate (r.layout.sub_right_top, null); Text_name_sub= ( TextView) View.findviewbyid (r.id.textview1)/** * Save Mv_url */textview_mvurl= (TextView) View.findviewbyid ( R.id.textview_gone);//load the acquired view into this control addview (view); this.currentactivity=context;this.shop=shop;this.zi_mvurl= Zi_mvurl;this.zi_name=zi_name;text_name_sub.settext (Zi_name); Textview_mvurl.settext (Zi_mvurl); View.setonclicklistener (New Onclicklistener () {//click event @overridepublic void OnClick (View v) {//TODO auto-generated Method Stubif (!getzi_mvurl (). Equals ("collect")) {//If not favorites, switch video System.out.println ("Click =====righttopchildslayouts== zi_name======== "+getzi_name ()); Videoview Mvideoview =currentactivity.getmvideoview (); Mvideoview.pause (); Uri uri = Uri.parse (geTzi_mvurl ()); Mvideoview.setvideouri (URI); Mvideoview.start ();} else {/** * is collected here if collection shows Favorites */system.out.println ("click = Favorites ====righttopchildslayouts==zi_name========" +getzi_name ()) ; if (getshop () = null) Toast.maketext (GetContext (), "collection Failed", Toast.length_short). Show (); New DBManager (GetContext ()). Exits (Getshop (). getshop_id ()))) {save2db (Getshop ());} else {//toast.maketext (context, " Collection ", Toast.length_short). Show (); Text_name_sub.settext (r.string.haven_collected);}});} private void save2db (Shop shop) {Contentresolver resolver = GetContext (). Getcontentresolver (); Contentvalues values = new Contentvalues (),//System.out.println ("Baocun11 ago--------"), Values.put ("Shop_name", Shop.getshopname ()); Values.put ("Address", shop.getaddress ()), Values.put ("Mv_url", Shop.getmv_url ()); Values.put (" Logo_url ", Shop.getlogo_url ()); Values.put (" Msg ", shop.getmsg ()); Values.put (" shop_id ", shop.getshop_id ());             Values.put ("Shop_phone", Shop.getshop_phone ()); Uri url = uri.parse ("Content://fang. ContentprOvider. mycontentprovider_media/"+ changliang.table); Resolver.insert (URL, values);//System.out.println (" Baocun11 successfully-----------"),//toast.maketext (GetContext ()," collection succeeded ", Toast.length_short). Show (); Public Shop getshop () {return shop;} public void Setshop (shop shop) {this.shop = shop;} Public String Getzi_name () {return zi_name;} public void Setzi_name (String zi_name) {this.zi_name = Zi_name;} Public String Getzi_mvurl () {return zi_mvurl;} public void Setzi_mvurl (String zi_mvurl) {this.zi_mvurl = Zi_mvurl;} This might not be appropriate. @overridepublic void Setonclicklistener (Onclicklistener l) {//TODO auto-generated method Stubsuper.setonclicklistener (l);//this.currentactivity.finish (); Videoview Mvideoview =currentactivity.getmvideoview (); Mvideoview.pause (); Uri uri = Uri.parse (zi_name); Mvideoview.setvideouri (URI); Mvideoview.start (); Mvideoview.setonpreparedlistener (new Mediaplayer.onpreparedlistener () {@Overridepublic void onprepared (MediaPlayer MediaPlayer) {//optional need Vitamio 4.0mediaplayer.setplaybackspeeD (1.0f);}});}} 

The sub_right_top.xml used above are as follows:

<pre name= "code" class= "HTML" ><relativelayout xmlns:android= "Http://schemas.android.com/apk/res/android" xmlns:tools= "Http://schemas.android.com/tools" android:id= "@+id/container" android:layout_width= "Match_parent" an droid:layout_height= "Match_parent" tools:context= "com.example.aaaa.MainActivity" tools:ignore= "Mergerootframe" ><linearlayout android:layout_width= "match_parent" android:layout_height= "wrap_content" > <!- -<imageview android:id= "@+id/imageview1" android:layout_width= "Wrap_content" Android:layout_heigh t= "Wrap_content" android:layout_gravity= "center_vertical" android:layout_marginleft= "8DP" android:src = "@drawable/mm_title_btn_compose_normal"/>--<textview android:id= "@+id/textview1" Android:la Yout_width= "Wrap_content" android:layout_height= "wrap_content" android:padding= "8DP" android:text= "wash vegetables Room "android:textcolor=" #fff "       Android:textsize= "18sp"/> <textview android:id= "@+id/textview_gone" Android:layout_wid        Th= "Wrap_content" android:layout_height= "wrap_content" android:padding= "8DP" android:text= "hidden"                    Android:textcolor= "#fff" android:textsize= "18sp" android:visibility= "Gone"/> </LinearLayout> </RelativeLayout>

Here's the dynamically added code: Start adding dynamically when their parent layout is loaded:

public class Maintoprightdialog extends Activity {//private mydialog dialog;private linearlayout layout;@ overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview ( R.layout.main_top_right_dialog);//Dialog=new Mydialog (this); layout = (LinearLayout) Findviewbyid (r.id.main_dialog_ Layout); Shop SHOP1 = (shop) getintent (). Getserializableextra ("Shop_inmvplayer"); MvplayActivity123 mvplayActivity123 = Mvplayactivity123.getinstance (); list<map<string, object>> mv_urls_list = null; String mv_urls = Shop1.getmv_url (); if (!mv_urls.equals ("null") && mv_urls! = null &&!mv_urls.equals ("") {try {mv_urls_list = (list<map<string, object>>) New Parsejson2list (). Parsejson2list (Shop1.getmv_url (). toString ());} catch (Jsonexception e) {//TODO auto-generated catch Blocke.printstacktrace ();}} else {mv_urls_list = Null;return;} Righttopchildslayouts layout_childs = null;/** * According to the Zi_mvurl distinguish is the URL or collection if the collection is collect */righTtopchildslayouts layout_collect = null; for (int i = 0; i < mv_urls_list.size (); i++) {layout_childs = new righttopchildslayouts (mvplayActivity123, SHOP1,MV _urls_list.get (i). Get ("_skey"). ToString (), Mv_urls_list.get (i). Get ("_svalue"). ToString ()); if (layout_childs! = NULL) {/* android:layout_width= "wrap_content" android:layout_height= "Wrap_content" Android:layout_alignpare Ntright= "true" android:layout_alignparenttop= "true" */layout.addview (layout_childs,130, LinearLayout.LayoutParams.WRAP_CONTENT);}} /** * Add a favorite if you have a favorite display */layout_collect=new righttopchildslayouts (mvplayActivity123, SHOP1, (new DBManager (this). Exits ( SHOP1.GETSHOP_ID ())? " Collection ":"), "collect"); Layout.addview (layout_collect,130,linearlayout.layoutparams.wrap_content);/* Layout.setonclicklistener (New Onclicklistener () {@Overridepublic void OnClick (View v) {//TODO auto-generated method Stubtoast.maketext (Getapplicationcontext (), "Hint: Click outside the window to close the window!" ", Toast.length_short). Show ();}}); */} @Overridepublic boOlean Ontouchevent (Motionevent event) {finish (); return true;}} 

This layout file (Main_dialog_layout) is as follows:

<?xml version= "1.0" encoding= "UTF-8"? ><relativelayout xmlns:android= "http://schemas.android.com/apk/res/       Android "Android:layout_width=" Fill_parent "android:layout_height=" fill_parent "> <relativelayout                     Android:layout_width= "Fill_parent" android:layout_height= "fill_parent" android:layout_margintop= "46DP" > <linearlayout android:id= "@+id/main_dialog_layout" android:layout_width = "Wrap_content" android:layout_height= "Wrap_content" android:layout_alignparentright= "true" android:l Ayout_alignparenttop= "true" android:orientation= "vertical" android:background= "@drawable/title_function_bg"         > <!--<linearlayout android:layout_width= "match_parent" android:layout_height= "Wrap_content"        android:layout_marginbottom= "3DP" > <textview android:layout_width= "wrap_content" Android:layout_height= "Wrap_conteNT "android:padding=" 8DP "android:text=" collection "android:textcolor=" #fff "android:textsize=" 18SP " /> </LinearLayout> </LinearLayout> </re Lativelayout></relativelayout>
