android 图片内存溢出

我的代码如下     is = new FileInputStream(new File(baseMagazinePath + this.bookId + "/" + fileList[currentImgNo] + ".png"));     iv.setImageDrawable(Drawable.createFromStream(is, "myStream")); 有时候出现内存溢出 改为     is = new FileInputStream(new File(baseMagazinePath + this.bookId + "/" + fileList[currentImgNo] + ".png"));     BitmapFactory.Options opts = new BitmapFactory.Options();     opts.inSampleSize = 4;     Bitmap bitmap = BitmapFactory.decodeStream(is, null, opts);     iv.setImageBitmap(bitmap); 就好了。
