我正在开发一个使用 aapt 从 apk 文件中获取一些信息的 Winform 应用程序。我得到了应用程序图标的路径，如下所示： *res/drawable-mdpi/app_icon.png* 我想从其路径中获取图标并将其推送到 ImageList。我该怎么做？感谢先进！

从 APK 文件中获取图标：

File file = new File("/mnt/sdcard/thinkandroidsimple/pam.apk");
String sourcePath = file.getPath();

if (sourcePath.endsWith(".apk")) {
        PackageInfo packageInfo = context.getPackageManager()
                   .getPackageArchiveInfo(filePath, PackageManager.GET_ACTIVITIES);
        if(packageInfo != null) {
            ApplicationInfo appInfo = packageInfo.applicationInfo;
            if (Build.VERSION.SDK_INT >= 8) {
                appInfo.sourceDir = sourcePath;
                appInfo.publicSourceDir = sourcePath;
            }
            Drawable icon = appInfo.loadIcon(context.getPackageManager());
            Bitmap bmpIcon = ((BitmapDrawable) icon).getBitmap();
        }
    }

看下面的代码可能对你有帮助

   public Drawable getFullResDefaultActivityIcon() {
            return getFullResIcon(Resources.getSystem(), android.R.mipmap.sym_def_app_icon);
        }

public Drawable getFullResIcon(Resources resources, int iconId) {
    Drawable d;
    try {
        ActivityManager activityManager = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);
        int iconDpi = activityManager.getLauncherLargeIconDensity();
        d = resources.getDrawableForDensity(iconId, iconDpi);
    } catch (Resources.NotFoundException e) {
        d = null;
    }

    return (d != null) ? d : getFullResDefaultActivityIcon();
}

public Drawable getFullResIcon(String packageName, int iconId) {
    Resources resources;
    try {
        resources = mContext.getPackageManager().getResourcesForApplication(packageName);
    } catch (PackageManager.NameNotFoundException e) {
        resources = null;
    }
    if (resources != null) {
        if (iconId != 0) {
            return getFullResIcon(resources, iconId);
        }
    }
    return getFullResDefaultActivityIcon();
}

public Drawable getFullResIcon(ResolveInfo info) {
    return getFullResIcon(info.activityInfo);
}

public Drawable getFullResIcon(ActivityInfo info) {
    Resources resources;
    try {
        resources = mContext.getPackageManager().getResourcesForApplication(info.applicationInfo);
    } catch (PackageManager.NameNotFoundException e) {
        resources = null;
    }
    if (resources != null) {
        int iconId = info.getIconResource();
        if (iconId != 0) {
            return getFullResIcon(resources, iconId);
        }
    }
    return getFullResDefaultActivityIcon();
}

private Drawable getAppIcon(ResolveInfo info) {
    return getFullResIcon(info.activityInfo);
}

使用 WinRar/WinZip 或等效软件打开 apk 文件（就像打开 .zip 文件一样）并从该路径中提取文件。
