Android获取壁纸名称

Question

我正在为我们公司开发一个 Android 应用程序，每次启动手机时都会将墙纸设置为特定的公司墙纸。最好检查壁纸是否已更改，而不是运行代码来更改壁纸。

有没有办法从当前壁纸中获取识别信息(例如文件名等)？

WallpaperManager wallpaperManager = WallpaperManager.getInstance(context);
WallpaperInfo wallpaperInfo = wallpaperManager.getWallpaperInfo();

为 wallpaperInfo 返回 null。

壁纸更改代码:

public static void setWallpaper(Context context) {

    // Has wallpaper changed?
    if (/*--wallpaperNotChanged--*/) {
        return;
    }

    try {

        // Setup
        Drawable drawable = context.getResources().getDrawable(R.drawable.test);
        DisplayMetrics displayMetrics = new DisplayMetrics();
        WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
        WallpaperManager wallpaperManager = WallpaperManager.getInstance(context);

        // Get display sizes
        windowManager.getDefaultDisplay().getMetrics(displayMetrics);

        // Create Bitmap
        Bitmap unscaledWallpaper = BitmapFactory.decodeResource(context.getResources(), R.drawable.test);
        Bitmap wallpaper = Bitmap.createScaledBitmap(unscaledWallpaper, displayMetrics.widthPixels, displayMetrics.heightPixels, true);

        // Set wallpaper
        wallpaperManager.setBitmap(wallpaper);

    } catch (Exception e){
        Toast.makeText(context, e.getMessage(), Toast.LENGTH_LONG).show();
    }
}
