Android dynamically adds controls and implements click events for each sub-control

Requirement: Click to enter a shop. Different sub-entries are displayed for different stores, such as disinfection room and washing room... These are more or less, so you need to dynamically Add:

First, customize the 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; impo Rt 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_su B, textview_mvurl; View view; MvplayActivity123 currentactivity;/*** the disinfection room of the food center */String zi_name; /** \ * video url of the disinfection room of the food center */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) {s Uper (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 obtained view to 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.setTex T (zi_mvurl); view. setOnClickListener (new OnClickListener () {// Click Event @ Overridepublic void onClick (View v) {// TODO Auto-generated method stubif (! GetZi_mvurl (). equals ("collect") {// if it is not a favorite, switch to the 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 {/*** add to favorites here. If you have added a favorite to your favorites, add it to favorites */System. out. println ("Click = favorites ==== RightTopChildsLayouts = zi_name ======" + getZi_name (); I F (getShop () = null) Toast. makeText (getContext (), "failed to add to Favorites", Toast. LENGTH_SHORT). show (); if (! (New DBManager (getContext ()). exits (getShop (). getShop_id () {save2db (getShop ();} else {// Toast. makeText (context, "added to Favorites", 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 before --------"); 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 successful -----------"); // Toast. makeText (getContext (), "successfully added to Favorites", 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 may be inappropriate @ 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 is as follows:

  
       
        
             
                        
       
  



The following code is dynamically added: when their parent layout is loaded, the code is dynamically added:
Public class MainTopRightDialog extends Activity {// private MyDialog dialog; private LinearLayout; @ 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
  
   
> 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
   
    
>) 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; /*** use zi_mvurl to identify the url or favorites as collect */RightTopChildsLayouts layout_collect = null; // for (int I = 0; I <mv_urls_list.size (); I ++) {layout_childs = new RightTopC HildsLayouts (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_alignParentRight = "true" android: layout_alignParentTop = "true" */layout. addView (layout_childs, 130, LinearLayout. layoutParams. WRAP_CONTENT) ;}}/*** Add a favorite item if it has been added to favorites */layout_collect = new RightTopChildsLayouts (mvplayActivity123, shop1, (new DBManager (this ). exits (shop1.getShop _ id ())? "Added to Favorites": "added to Favorites"), "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 (), "prompt: Click the window to close the window! ", Toast. LENGTH_SHORT). show () ;}}); * //} @ Overridepublic boolean onTouchEvent (MotionEvent event) {finish (); return true ;}}
   
  
The layout file main_dialog_layout is as follows:
