如何使用导航组件创建固定快捷方式？

Question

所以我关注了 Chet Haase 的文章。

文章：https://medium.com/androiddevelopers/navigating-with-deep-links-910a4a6588c

在本文中，他解释了如何使用带有导航组件的深层链接。固定的快捷方式构建器需要一个 Intent，但 findNavController 辅助方法 returns PendingIntent 的对象。

文章中获取pendingIntent的方法。

 val pendingIntent = navController
        .createDeepLink()
        .setDestination(R.id.donutEntryDialogFragment)
        .setArguments(arg)
        .createPendingIntent()

ShortcutInfoBuilder 方法

val pinShortcutBuilder = ShortcutInfo.Builder(
                              requireContext(),
                              "id"
                              )
pinShortcutBuilder
     .setShortLabel("someLabel")
     .setIntent(intent)  // takes an object of Intent

那么，如何创建固定快捷方式？

Answer 1

我们使用 URI 创建深层链接，Intent 构造函数的参数之一是 URI。我们可以直接将 URI 传递给构造函数并将 activity 设置为 MainActity（因为单个 activity 范例）。

val intent = Intent(
                      Intent.ACTION_VIEW,
                      "myapp://navdonutcreator.com/donutcreator".toUri(),
                      requireContext(),
                      MainActivity::class.java
                    )

现在在您要打开的片段中使用相同的 URI。

<fragment
    android:id="@+id/targetFragment"
    android:name="com.example.myapp.ui.TargetFragment"
    tools:layout="@layout/fragment_target">
    <deepLink
        android:id="@+id/deepLink"
        app:uri="myapp://navdonutcreator.com/donutcreator" />
</fragment>

现在把所有东西缝合起来，

 val shortcutManager = ContextCompat.getSystemService(
                        requireContext(),
                        ShortcutManager::class.java
                    )

                    if (shortcutManager != null && shortcutManager.isRequestPinShortcutSupported) {

                        val intent = Intent(
                            Intent.ACTION_VIEW,
                            "myapp://navdonutcreator.com/donutcreator".toUri(),
                            requireContext(),
                            MainActivity::class.java
                        )

                        val pinShortcutBuilder =
                            ShortcutInfo.Builder(
                                requireContext(),
                                "someId"
                            )
                        pinShortcutBuilder.setShortLabel("someLabel)
                            .setIntent(intent)

                        val pinShortcutInfo = pinShortcutBuilder.build()

                        // Create the PendingIntent object only if your app needs to be notified
                        // that the user allowed the shortcut to be pinned. Note that, if the
                        // pinning operation fails, your app isn't notified. We assume here that the
                        // app has implemented a method called createShortcutResultIntent() that
                        // returns a broadcast intent.
                        val pinnedShortcutCallbackIntent =
                            shortcutManager.createShortcutResultIntent(pinShortcutInfo)

                        // Configure the intent so that your app's broadcast receiver gets
                        // the callback successfully.For details, see PendingIntent.getBroadcast().
                        val successCallback = PendingIntent.getBroadcast(
                            requireContext(), 0,
                            pinnedShortcutCallbackIntent, 0
                        )

                        shortcutManager.requestPinShortcut(
                            pinShortcutInfo,
                            successCallback.intentSender
                        )
                    }
