android - generate main.xml inside onCreate() -

-

is possible generate main.xml inside oncreate()? such as:

package avm.project;  import java.io.bufferedwriter; import java.io.file; import java.io.filewriter; import java.lang.reflect.field;  import android.app.activity; import android.content.res.resources; import android.os.bundle; import android.util.log; import android.view.view; import android.widget.button; import android.widget.viewflipper;   public class avmordersystemactivity extends activity {        viewflipper flipper;         @override        public void oncreate(bundle icicle) {          super.oncreate(icicle);          //file[] listoffiles = folder.listfiles();          /*for (int = 0; < listoffiles.length; i++) {             if (listoffiles[i].isfile()) {                 log.i("xml generator","file " + listoffiles[i].getname());             } else if (listoffiles[i].isdirectory()) {                 log.i("xml generator","directory " + listoffiles[i].getname());             }         }*/         string xml="";         xml=xml+"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n";          xml=xml+"<relativelayout xmlns:android=\"http://schemas.android.com/apk/res/android\"\n"+                 "android:layout_width=\"fill_parent\" android:layout_height=\"wrap_content\"\n"+                 "android:orientation=\"horizontal\" android:padding= \"5px\">\n";         xml=xml+"<viewflipper android:id=\"@+id/adflipper\"\n"+                 "android:inanimation=\"@android:anim/fade_in\" android:outanimation=\"@android:anim/slide_out_right\"\n"+                 "android:paddingleft=\"15px\" android:layout_width=\"fill_parent\"\n"+                 "android:layout_height=\"fill_parent\" android:autostart=\"true\"\n"+                 "android:flipinterval=\"5000\">";          resources a=this.getresources();         try         {             (int i=0x7f020000 ;i<0x7f020020;i++)             {                 string name=a.getresourcename(i);                 xml=xml+"<imageview android:layout_width=\"fill_parent\" android:src=\"@"+name.substring(name.indexof(':')+1)+"\"\n"+                     "android:layout_height=\"fill_parent\"></imageview>\n";             }         }         catch(exception e)         {             log.i("resoruces","exception");             e.printstacktrace();         }         xml=xml+"</viewflipper>\n</relativelayout>";         xml=xml+"<!--xxx-->";           try{             // create file              filewriter fstream = new filewriter("res/layout/main.xml");             bufferedwriter out = new bufferedwriter(fstream);             out.write(xml);             //close output stream             out.close();         }catch (exception e){//catch exception if             log.i("xml write","exception");             e.printstacktrace();         }          setcontentview(r.layout.main);           flipper=(viewflipper)findviewbyid(r.id.adflipper);          button btn=(button)findviewbyid(r.id.restbutton);           btn.setonclicklistener(new view.onclicklistener() {            public void onclick(view view) {              flipper.shownext();           }          });        }      }

i have implemented code , can project drawables generate main.xml accordingly not working (i got exception: file not found res/layout/main.xml). (my aim generate main.xml according varying number of png images) doing wrong, possible on or there other solution?

thanks.

you can change src of imageview dynamically without having generate xml.

imageview imageview = (imageview) findviewbyid(r.id.your_image_view); imageview.setimagedrawable(getresources().getdrawable(r.drawable.your_png));

and can add more creating them dynamically , adding them parent relativelayout:

for (int i=0x7f020000 ;i<0x7f020020;i++)     imageview imageview = new imageview(this);     imageview.setbackgroundresource(r.drawable.your_png_reference);     relativelayout ll = (relativelayout) findviewbyid(r.id.your_relative_layout_id);     ll.addview(imageview); }

actionscript 3 - TweenLite does not work with object -

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
