目前我的工作方式如下：
[animation_image.xml]
<?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/artistes"
android:duration="5000"/>
<item
android:drawable="@drawable/couple1"
android:duration="5000"/>
<item
android:drawable="@drawable/couple2"
android:duration="5000"/>
<item
android:drawable="@drawable/couple3"
android:duration="5000"/>
<item
android:drawable="@drawable/enfant"
android:duration="5000"/>
<item
android:drawable="@drawable/manege"
android:duration="5000"/>
<item
android:drawable="@drawable/manege2"
android:duration="5000"/>
<item
android:drawable="@drawable/metropolitain"
android:duration="5000"/>
<item
android:drawable="@drawable/panoramique"
android:duration="5000"/>
<item
android:drawable="@drawable/sacrecoeur"
android:duration="5000"/>
<item
android:drawable="@drawable/velo"
android:duration="5000"/>
</animation-list>
[MainActivity.java]
ImageView mImageAnimation = (ImageView) findViewById(R.id.images);
AnimationDrawable mAnimationDrawableImages = (AnimationDrawable) mImageAnimation.getDrawable();
mAnimationDrawableEq.start();

我最终创建了一个Scheduler类：
public class Scheduler {
private OnScheduleTimeListener mListener;
private Handler mHandler;
private int mInterval; // Between each executions in milli
private static final int DELAY = 100; // before first execution
private boolean mIsTimerRunning;
private int mCount = 0;
private int mCountMax = 1;
private Mode mMode;
public static enum Mode {
ASC, // count
DESC, // decount
}
public static interface OnScheduleTimeListener {
public void onScheduleTime(int count);
}
/**
* @param interval
* time interval between each loop in milli second
* @param countMax
* maximum of itteration (-1 for infinite)
* @param mode
* either ASC or DESC order
*/
public Scheduler(int interval, int countMax, Mode mode) {
super();
if (countMax == -1) {
mCountMax = Integer.MAX_VALUE;
} else {
if (mode.equals(Mode.DESC)) {
mCount = countMax;
}
mCountMax = countMax;
}
mMode = mode;
mInterval = interval;
mHandler = new Handler();
}
private final Runnable mRunnable = new Runnable() {
@Override
public void run() {
// Do stuff
mListener.onScheduleTime(mCount);
if (mMode.equals(Mode.ASC)) {
mCount++;
} else {
if (mCount == 0) {
stopTimer();
return;
}
mCount--;
}
// Repeat
mHandler.postDelayed(mRunnable, mInterval);
}
};
public void setOnScheduleTimeListener(OnScheduleTimeListener listener) {
mListener = listener;
}
public void startTimer() {
mIsTimerRunning = true;
mHandler.postDelayed(mRunnable, DELAY);
}
public void stopTimer() {
mIsTimerRunning = false;
mHandler.removeCallbacks(mRunnable);
}
public boolean isTimerRunning() {
return mIsTimerRunning;
}
}

不要使用xml来创建动画。创建一个将按需加载图像的视图。
例如（简单而不预取）：
//I just wrote this here so there might be some errors
static int images[] = new int[] {R.drawable.artistes, R.drawable.couple1, R.drawable.couple2}; //ETC intialize
ImageView view; //initialize
Handler handler; //initialize
int index = 0;
Runnable updater = new Runnable() {
public void run() {
if(index == images.length) {
//animation is done
}
else {
view.setImageResource(images[index++]);
handler.postDelayed(this, 5000);
}
}
};
private void startAnimation() {
handler.post(updater);
}
