加载本地缓存图片

 

List<String> imgList = new ArrayList<String>();        imgList.add("本地图片地址");      imgList.add("本地图片地址");        for (int i = 0; i < imgList.size(); i++) {//路径地址变转变成 //Drawable            Drawable drawable = getDrawable(imgList.get(i));            if (drawable != null) {//添加到动画对象中                anim.addFrame(drawable, 200);            }        }        anim.setOneShot(false);        imageView.setImageDrawable(anim);        anim.start();

  工具类

 

    public Drawable getDrawable(String filePath) {        Bitmap bitmap = readBitMap(filePath);        if (bitmap != null) {            BitmapDrawable bitmapDrawable = new BitmapDrawable(getResources(), bitmap);            return bitmapDrawable;        }        return null;    }    public static Bitmap readBitMap(String filePath) {        BitmapFactory.Options opt = new BitmapFactory.Options();        opt.inPreferredConfig = Bitmap.Config.RGB_565;        opt.inPurgeable = true;        opt.inInputShareable = true;        return decodeBmp(filePath, opt);    }    public static Bitmap decodeBmp(String imgPath, BitmapFactory.Options opts) {        Bitmap dstBmp = null;        FileInputStream fis;        try {            fis = new FileInputStream(imgPath);            dstBmp = BitmapFactory.decodeStream(fis, null, opts);        } catch (FileNotFoundException e) {            e.printStackTrace();        } catch (OutOfMemoryError e) {            opts.inSampleSize += 1;            opts.inPreferredConfig = Bitmap.Config.RGB_565;            opts.inPurgeable = true;            opts.inInputShareable = true;            opts.inJustDecodeBounds = false;            dstBmp = decodeBmp(imgPath, opts);        }        return dstBmp;    }
