[英]Using Serializable as deep link argument with Android Navigation Component
[英]Android navigation component passing argument with safeArgs and deep link
我有一个导航 xml 的功能如下 -
<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/navigation_featureB.xml"
app:startDestination="@id/FragmentB">
<fragment
android:id="@+id/FragmentB"
android:name="FragmentB"
android:label="FragmentB">
<deepLink app:uri="App://FragmentB" />
</fragment>
</navigation>
在我的FeatureA
片段中,我执行以下操作 -
val uri = Uri.parse("App://FragmentB")
findNavController().navigate(uri)
我知道如何在没有深度链接的情况下使用safeArgs
。 如何通过深度链接将数据传递给其他功能?
您可以执行以下操作
首先在navigation.xml
中添加参数。xml
<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/navigation_featureB.xml"
app:startDestination="@id/FragmentB">
<fragment
android:id="@+id/FragmentB"
android:name="FragmentB"
android:label="FragmentB">
<argument
android:name="yourarg"
android:defaultValue="Argument Default Value"/>
<deepLink app:uri="App://FragmentB/{yourarg}" />
</fragment>
</navigation>
然后你可以这样称呼它
val args = Bundle()
args.putString("yourarg", "Argument Value")
val deeplink = findNavController().createDeepLink()
.setDestination(R.id.FragmentB)
.setArguments(args)
.createPendingIntent()
val builder = NotificationCompat.Builder(
context, "deeplink")
.setContentTitle("Deep link with data")
.setContentText("Deep link with data to Android")
.setSmallIcon(R.drawable.ic_android)
.setContentIntent(deeplink)
.setAutoCancel(true)
val notificationManager =
context?.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.notify(0, builder.build())

无通知
首先,在navigation.xml中添加参数
<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/navigation_featureB.xml"
app:startDestination="@id/FragmentB">
<fragment
android:id="@+id/FragmentB"
android:name="FragmentB"
android:label="FragmentB">
<argument
android:name="yourarg"
android:defaultValue="Argument Default Value"/>
<deepLink app:uri="App://FragmentB/{yourarg}" />
</fragment>
</navigation>
然后你可以这样称呼它
val uri = Uri.parse("App://FragmentB/yourarghere")
findNavController().navigate(uri)
然后您可以使用此代码获取参数
val argument = arguments?.getString("yourarg")
// Or with Safe Args
val safeArgs: FragmentBArgs by navArgs()
val yourarg = safeArgs.yourarg

以上答案显示了如何使用字符串数据类型。 但是如果你想传递自定义对象,safe-args 也很有效;
<fragment
android:id="@+id/verification_fragment"
android:name="com.appname.ui.verification.VerificationFragment"
android:label="VerificationFragment">
<argument
android:name="verificationType"
android:defaultValue="PHONE"
app:argType="com.appname.core.model.VerificationType" />
<deepLink app:uri="android-app://com.appname/verification_fragment?verificationType={verificationType}" />
</fragment>
将自定义属性传递给深度链接;
val request = NavDeepLinkRequest.Builder
.fromUri("android-app://appname/verification_fragment?verificationType=${VerificationType.MAIL}".toUri())
.build()
findNavController().navigate(request)
从目标片段中读取属性;
private val args: VerificationFragmentArgs by navArgs()
args.verificationType
