我想让我的Android应用程序的用户在他们想要的时候隐藏/取消隐藏它。我已经有了执行hide/unhide操作的代码，隐藏工作正常。但是现在我如何调用unhide方法来让应用返回呢？我的意思是，如果应用程序是隐藏的，用户可以在哪里，让我们说，“点击一个按钮”，调用方法，使应用程序取消隐藏？
下面是我的hide/unhide代码：

// method to hide the app icon
 public static void hideAppIcon(final Context context)
    {
     PackageManager p = context.getPackageManager();
     // activity which is first time open in manifest file which is declare as <category android:name="android.intent.category.LAUNCHER" />
     ComponentName componentName = new ComponentName(context, SplashActivity.class);
     p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
    }

 // method to unhide the app icon
 public static void unhideAppIcon(final Context context)
    {
     PackageManager p = context.getPackageManager();
     // activity which is first time open in manifest file which is declare as <category android:name="android.intent.category.LAUNCHER" />
     ComponentName componentName = new ComponentName(context, SplashActivity.class);
     p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
    }
