想做一個逐幀動畫，用了一百來張圖片，結果記憶體溢位了，找了半天最後算是解決了。

本來是在drawable裡面寫一個animation-list，設定ImageView的backgroud，

然後在Activity裡面

animationDrawable = (AnimationDrawable)mImageView.getBackground();

animationDrawable.start();

最後採用的解決辦法是這個http://www.kankanews.com/ICkengine/archives/86482.shtml

稍微改動了一下。

裡面有三個構造方法，和兩個播放的方法，直接構造就可以播放動畫了

package com.example.animationoom;

import android.os.Handler;
import android.widget.ImageView;

public class SceneAnimation  {
	private ImageView mImageView;
	private int[] mFrameRess;// 圖片
	private int[] mDurations;
	private int mDuration;
	
	private Handler handler = new Handler();
	Runnable mRunnable;

	private int mLastFrameNo;
	private long mBreakDelay;
	
	//引數包括pDurations陣列，執行播放play(1);
	public SceneAnimation(ImageView pImageView, int[] pFrameRess, int[] pDurations) {
		mImageView = pImageView;
		mFrameRess = pFrameRess;
		mDurations = pDurations;
		mLastFrameNo = pFrameRess.length - 1;

		mImageView.setBackgroundResource(mFrameRess[0]);
		play(1);
	}
	
	//引數包括一個int 的執行時間 pDuration， 執行迴圈播放playConstant(1);
	public SceneAnimation(ImageView pImageView, int[] pFrameRess, int pDuration) {
		mImageView = pImageView;
		mFrameRess = pFrameRess;
		mDuration = pDuration;
		mLastFrameNo = pFrameRess.length - 1;

		mImageView.setBackgroundResource(mFrameRess[0]);
		playConstant(1);
	}
	
	//引數包括一個int的pDuration，一個long的pBreakDelay，表示每次播放的間隔，執行迴圈播放playConstant(1);
	public SceneAnimation(ImageView pImageView, int[] pFrameRess,int pDuration, long pBreakDelay) {
		mImageView = pImageView;
		mFrameRess = pFrameRess;
		mDuration = pDuration;
		mLastFrameNo = pFrameRess.length - 1;
		mBreakDelay = pBreakDelay;

		mImageView.setBackgroundResource(mFrameRess[0]);
		playConstant(1);
	}

	private void play(final int pFrameNo) {
		
		mRunnable = new Runnable() {
			public void run() {
				mImageView.setBackgroundResource(mFrameRess[pFrameNo]);
				if (pFrameNo == mLastFrameNo)
					play(0);
				else
					play(pFrameNo + 1);
			}
		};
		handler.postDelayed( mRunnable, mDurations[pFrameNo]);
	}

	private void playConstant(final int pFrameNo) {
		Handler handler = new Handler();
		handler.postDelayed(new Runnable() {
			public void run() {
				mImageView.setBackgroundResource(mFrameRess[pFrameNo]);

				if (pFrameNo == mLastFrameNo)
					playConstant(0);
				else
					playConstant(pFrameNo + 1);
			}
		}, pFrameNo == mLastFrameNo && mBreakDelay > 0 ? mBreakDelay : mDuration);
	}
	

};
 

而且目前是不能實現單詞播放的，還需要做些改動。
