First, the GetView method of rewriting Baseadapter

1 @Override2  PublicView GetView (intposition, View Convertview, ViewGroup parent) {3 view view;4     if(Convertview = =NULL) {5View = View.inflate (Getapplicationcontext (), R.layout.item_phone,NULL);6}Else {7View =Convertview;8     }9TextView name =(TextView) View.findviewbyid (r.id.tv_name);TenTextView phone =(TextView) View.findviewbyid (r.id.tv_phone); One  A Name.settext (personlist.get (position). GetName ()); - Phone.settext (personlist.get (position). Getphone ()); -  the     returnview; -}

Second, arrayadapter structure

1 // Parameters 2 // Context    The current context. 3 // Resource    The resource ID for a layout file containing a TextView to use when instantiating views (only one TextView layout resource). 4 // Objects    The objects to represent in the ListView. 5  Public int resource, list<t> objects)

1 @Override2 protected voidOnactivityresult (intRequestcode,intResultCode, Intent data) {3     if(ResultCode = = 10) {4Et_phone.settext (Data.getstringextra ("Phone"));5}Else if(ResultCode = = 20) {6Et_content.settext (Data.getstringextra ("content"));7     }8}

Iv. Sending SMS

1  Public voidbtnsendmsg (View v) {2String content =Et_content.gettext (). toString (). Trim ();3String phone =Et_phone.gettext (). toString (). Trim ();4 5Smsmanager sender =Smsmanager.getdefault ();6Arraylist<string> msglist =sender.dividemessage (content);7 8      for(intI=0;i<msglist.size (); i++){9Sender.sendtextmessage (Phone,NULL, Msglist.get (i),NULL,NULL);Ten     } One}
