i new android , having trouble playing animated .gif file in background of layout. when run application background single frame of animated .gif, picture. have done research in 2 areas:
the link below got help.
the link below makes me think errors receiving have classes being set private, public, or protected.
and here's code -------------------------------------------------------------------------------------------------------------------
errors denoted :: error # :: full descriptions below code.
import java.io.inputstream; import android.os.bundle; import android.app.activity; import android.graphics.canvas; import android.graphics.color; import android.graphics.movie; import android.view.menu; import android.view.view; public class mainactivity extends activity { @override public void oncreate(bundle savedinstancestate){ super.oncreate(savedinstancestate); setcontentview(new mygifview()); :: error 1 :: } } private class mygifview extends view{ :: error 2 :: movie movie,movie1; inputstream is=null , is1=null; long moviestart; public gifview(context context) { :: error 3 :: super(context); :: error 4 :: is=context.getresources().openrawresource(r.drawable.swing); movie=movie.decodestream(is); } @override protected void ondraw(canvas canvas) { canvas.drawcolor(color.white); super.ondraw(canvas); long now=android.os.systemclock.uptimemillis(); system.out.println("now="+now); if (moviestart == 0) { // first time moviestart = now; } system.out.println("\tmoviestart="+moviestart); int reltime = (int)((now - moviestart) % movie.duration()) ; system.out.println("time="+reltime+"\treltime="+movie.duration()); movie.settime(reltime); movie.draw(canvas,this.getwidth()/2-20,this.getheight()/2-40); this.invalidate(); } } :: errors list :: errors list :: errors list :: errors list :: errors list :: errors list ::

i have created animation list = res/drawable-hdpi/progress_animation.xml
<?xml version="1.0" encoding="utf-8"?> <animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/selected" android:oneshot="false"> <item android:drawable="@drawable/frame02" android:duration="50" /> <item android:drawable="@drawable/frame03" android:duration="50" /> <item android:drawable="@drawable/frame04" android:duration="50" /> <item android:drawable="@drawable/frame05" android:duration="50" /> <item android:drawable="@drawable/frame06" android:duration="50" /> <item android:drawable="@drawable/frame07" android:duration="50" /> <item android:drawable="@drawable/frame08" android:duration="50" /> <item android:drawable="@drawable/frame09" android:duration="50" /> <item android:drawable="@drawable/frame10" android:duration="50" /> ......................................... <item android:drawable="@drawable/frame57" android:duration="50" /> <item android:drawable="@drawable/frame58" android:duration="50" /> </animation-list> .
.
i have created layout file host image view = res/layout/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: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=".mainactivity" > <imageview android:id="@+id/swing_play" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </relativelayout> .
java class activity call imageview , animationdrawable = com.example.apptwo/mainactivity.java
.
package com.exampleone.apptwo; import android.os.bundle; import android.app.activity; import android.graphics.drawable.animationdrawable; import android.view.menu; import android.widget.imageview; public class mainactivity extends activity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.acivity_main); imageview img = (imageview)findviewbyid(r.id.swing_play); img.setbackgroundresource(r.drawable.progress_animation); animationdrawable frameanimation = (animationdrawable) img.getbackground(); frameanimation.start(); } } .
the ide not flag errors in code. however, when run application emulator displays white background message "unfortunately, apptwo has stopped."
the errorlog reads = "unhandled event loop exception"

as martin says, android not support gifs. workaround, android offers animation list/animationdrawable. need convert gif individual frames [.png files]. use gimp conversion
this gif can broken down frames:
save them frame01.png, frame02.png, , on, , create animation-list xml file, say, progress_animation.xml
<animation-list android:id="@+id/selected" android:oneshot="false"> <item android:drawable="@drawable/frame01" android:duration="50" /> <item android:drawable="@drawable/frame02" android:duration="50" /> <item android:drawable="@drawable/frame03" android:duration="50" /> .... <item android:drawable="@drawable/framen" android:duration="50" /> to begin animation, need cast image animationdrawable, , call start() on it
animationdrawable progressanimation = (animationdrawable) yourimageview.getbackground(); progressanimation.start();
