夜深也是無聊，翻看以前的老代碼，發現那個我們經常用的菊花圈，原來是幀動畫做的，有點意思。突然感覺幀動畫做的東西效果不錯啊，至少看起來聽耐看的。開工上代碼：

先是布局檔案：

<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:background="@drawable/login_bg" >   <ProgressBar       android:layout_width="24dip"       android:layout_height="24dip"       android:layout_alignParentBottom="true"       android:layout_centerHorizontal="true"       android:layout_marginBottom="100dip"       android:indeterminate="true"       android:indeterminateDrawable="@drawable/progress_animation" /></RelativeLayout>

<?xml version="1.0" encoding="utf-8"?><animation-list xmlns:android="http://schemas.android.com/apk/res/android"    android:oneshot="false" >    <item        android:drawable="@drawable/pull_ref_pb_1"        android:duration="80"/>    <item        android:drawable="@drawable/pull_ref_pb_2"        android:duration="80"/>    <item        android:drawable="@drawable/pull_ref_pb_3"        android:duration="80"/>    <item        android:drawable="@drawable/pull_ref_pb_4"        android:duration="80"/>    <item        android:drawable="@drawable/pull_ref_pb_5"        android:duration="80"/>    <item        android:drawable="@drawable/pull_ref_pb_6"        android:duration="80"/>    <item        android:drawable="@drawable/pull_ref_pb_7"        android:duration="80"/>    <item        android:drawable="@drawable/pull_ref_pb_8"        android:duration="80"/>    <item        android:drawable="@drawable/pull_ref_pb_9"        android:duration="80"/>    <item        android:drawable="@drawable/pull_ref_pb_10"        android:duration="80"/>    <item        android:drawable="@drawable/pull_ref_pb_11"        android:duration="80"/>    <item        android:drawable="@drawable/pull_ref_pb_12"        android:duration="80"/></animation-list>

package com.woyou.frameanimation;import java.util.Timer;import java.util.TimerTask;import android.content.Intent;import android.os.Bundle;import android.support.v7.app.ActionBarActivity;/** * 菊花圈布局 * @author Administrator *  */public class FrameActivity extends ActionBarActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.login_main);Timer timer = new Timer();timer.schedule(new TimerTask() {@Overridepublic void run() {Intent intent = new Intent(FrameActivity.this, LoginActivity.class);startActivity(intent);finish();}}, 5000);}}

定時久點在讓他跳轉過去吧...
