Java Android ImageLoader，如何将ViewPager中的图像设置为壁纸

嗨，我正在使用nostra13/Android通用图像加载器库

我想做的是，当图像加载到ViewPager时，它会将其设置为壁纸

我现在的问题是。当我加载图像2时。图像1设置为墙纸，有时设置为ramdom图像

这是我的密码：

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.i(TAG, "onCreate");

        options = new DisplayImageOptions.Builder()
                .showImageForEmptyUri(R.drawable.ic_empty)
                .showImageOnFail(R.drawable.ic_error)
                .resetViewBeforeLoading(true)
                .cacheOnDisk(true)
                //.imageScaleType(ImageScaleType.EXACTLY)
                .imageScaleType(ImageScaleType.EXACTLY_STRETCHED)
                .bitmapConfig(Bitmap.Config.RGB_565)
                .considerExifParams(true)
                .displayer(new FadeInBitmapDisplayer(300))
                .build();

你说的壁纸是指手机的背景还是仅仅是一个布局背景？PageAdapter来自框架？因为我在使用FragmentStateAdapter时看不到onCreateView。手机墙纸-我已经更新了我的代码我也有同样的问题，
