Android imageView drawable lag

Question

我使用https://github.com/apl-devs/AppIntro repo为我的Android APP制作介绍。

我在/drawable/文件夹中添加了3张图片。

1. 1024x768 - 123 892个八位字节 - JPG
2. 1024x768 - 98 304个八位字节 - JPG
3. 1024x1024 - 585 728个八位字节 - PNG

但是当我用我的片段切换时，这已经滞后了很多。如果我删除这个可绘制的图片，那就行了......

你可以试着帮我解决吗？

 addSlide(AppIntroFragment.newInstance("Welcome!",
                "This is a demo of the AppIntro library.",
                R.drawable.logov2_intro2,
                Color.parseColor("#616161")));

        addSlide(AppIntroFragment.newInstance("Clean App Intros",
                "This library offers developers the ability to add clean app intros at the start of their apps.",
                R.drawable.tuto1_jpg,
                Color.parseColor("#1565c0")));

        addSlide(AppIntroFragment.newInstance("Simple, yet Customizable",
                "The library offers a lot of customization, while keeping it simple for those that like simple.",
                R.drawable.tuto2_jpg,
                Color.parseColor("#1976d2")));

        addSlide(AppIntroFragment.newInstance("Explore",
                "Feel free to explore the rest of the library demo!",
                R.drawable.logov2_intro2,
                Color.parseColor("#616161")));
