Anda dapat menambahkan tindakan ke
Snackbar
agar pengguna dapat merespons pesan Anda. Saat Anda melakukannya, Snackbar akan menempatkan tombol di samping teks pesan, dan pengguna dapat
memicu tindakan Anda dengan mengetuk tombol. Misalnya, aplikasi email mungkin menempatkan
tombol urungkan pada pesan "email diarsipkan". Jika pengguna mengetuk
tombol urungkan, aplikasi akan mengembalikan email ke luar arsip.
Gambar 1.Snackbar dengan tombol tindakan urungkan yang
memulihkan item yang dihapus.
Untuk menambahkan tindakan ke pesan Snackbar, tentukan objek pemroses
yang mengimplementasikan
antarmuka
View.OnClickListener. Sistem akan memanggil metode
onClick()
pemroses jika pengguna mengetuk tindakan pesan. Misalnya, cuplikan ini menampilkan
pemroses untuk tindakan urungkan:
Kotlin
classMyUndoListener:View.OnClickListener{funonClick(v:View){// Code to undo the user's last action.}}
Java
publicclassMyUndoListenerimplementsView.OnClickListener{@OverridepublicvoidonClick(Viewv){// Code to undo the user's last action.}}
Gunakan salah satu metode
setAction()
untuk menyematkan pemroses ke Snackbar. Lampirkan pemroses sebelum Anda memanggil show(), seperti yang ditunjukkan dalam contoh kode ini:

Learn how to add notifications in Compose. \n[Snackbar →](/develop/ui/compose/components/snackbar) \n\nYou can add an action to a\n[Snackbar](/reference/com/google/android/material/snackbar/Snackbar)\nto let the user respond to your message. When you do this, the\n`Snackbar` puts a button next to the message text, and the user can\ntrigger your action by tapping the button. For example, an email app might put\nan *undo* button on its \"email archived\" message. If the user taps the\n*undo* button, the app takes the email back out of the archive.\n**Figure 1.** A `Snackbar` with an undo action button that restores a removed item.\n\nTo add an action to a `Snackbar` message, define a listener object\nthat implements the\n[View.OnClickListener](/reference/android/view/View.OnClickListener)\ninterface. The system calls your listener's\n[onClick()](/reference/android/view/View.OnClickListener#onClick(android.view.View))\nmethod if the user taps the message action. For example, this snippet shows a\nlistener for an undo action: \n\n### Kotlin\n\n```kotlin\nclass MyUndoListener : View.OnClickListener {\n\n fun onClick(v: View) {\n // Code to undo the user's last action.\n }\n}\n```\n\n### Java\n\n```java\npublic class MyUndoListener implements View.OnClickListener {\n\n @Override\n public void onClick(View v) {\n\n // Code to undo the user's last action.\n }\n}\n```\n\nUse one of the\n[setAction()](/reference/com/google/android/material/snackbar/Snackbar#setAction(int, android.view.View.OnClickListener))\nmethods to attach the listener to your `Snackbar`. Attach the\nlistener before you call\n[show()](/reference/com/google/android/material/snackbar/BaseTransientBottomBar#show()),\nas shown in this code sample: \n\n### Kotlin\n\n```kotlin\nval mySnackbar = Snackbar.make(findViewById(R.id.myCoordinatorLayout),\n R.string.email_archived, Snackbar.LENGTH_SHORT)\nmySnackbar.setAction(R.string.undo_string, MyUndoListener())\nmySnackbar.show()\n```\n\n### Java\n\n```java\nSnackbar mySnackbar = Snackbar.make(findViewById(R.id.myCoordinatorLayout),\n R.string.email_archived, Snackbar.LENGTH_SHORT);\nmySnackbar.setAction(R.string.undo_string, new MyUndoListener());\nmySnackbar.show();\n```\nIf you are using [Jetpack Compose](/jetpack/compose), you can show a [SnackbarHost](/reference/kotlin/androidx/compose/material/package-summary#SnackbarHost(androidx.compose.material.SnackbarHostState,androidx.compose.ui.Modifier,kotlin.Function1)), as shown in the following example: \n\n### Kotlin\n\n```kotlin\n override fun onCreate(savedInstanceState: Bundle?) {\n\n super.onCreate(savedInstanceState)\n\n setContent {\n DACPlaygroundTheme {\n val snackbarHostState = remember { SnackbarHostState() }\n val scope = rememberCoroutineScope()\n Scaffold(\n snackbarHost = { SnackbarHost(snackbarHostState) },\n content = { padding -\u003e\n Button(\n modifier = Modifier.padding(padding),\n onClick = {\n scope.launch {\n snackbarHostState.showSnackbar(\n message = \"1 item removed\",\n actionLabel = \"UNDO\",\n duration = SnackbarDuration.Short\n ).run {\n when (this) {\n Dismissed -\u003e Log.d(\"SNACKBAR\", \"Dismissed\")\n ActionPerformed -\u003e Log.d(\"SNACKBAR\", \"UNDO CLICKED\")\n }\n }\n }\n }\n ) { Text(\"Show snackbar\") }\n }\n )\n }\n }\n }\n \n```\n| **Note:** A `Snackbar` automatically goes away after a short time, so the user might not see the message or have a chance to tap the button. For this reason, offer other ways to perform `Snackbar` actions."]]
