Toast messages are commonly seen in Android apps. Toasts are useful for showing a short and straightforward feedback message to the users. Let’s learn how to create and show toast messages in Android using Jetpack Compose.
Let’s show a toast message when a button is pressed. You need to pass the context, text, and duration to show the toast message.
val context = LocalContext.current
Button(onClick = { Toast.makeText(context,"This a simple toast tutorial!", Toast.LENGTH_LONG).show() }) {
Text("Click here to show toast!")
}Following is the output.
Following is the complete example to show Android toast.
package com.example.myapplication
import android.os.Bundle
import android.widget.Toast
import androidx.activity.ComponentActivity
import androidx.activity.compose.setContent
import androidx.compose.foundation.layout.*
import androidx.compose.material.*
import androidx.compose.runtime.*
import androidx.compose.ui.Modifier
import androidx.compose.ui.platform.LocalContext
import androidx.compose.ui.tooling.preview.Preview
import androidx.compose.ui.unit.dp
import com.example.myapplication.ui.theme.MyApplicationTheme
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
MyApplicationTheme {
Surface(
color = MaterialTheme.colors.background,
modifier = Modifier.padding(20.dp)
) {
ToastExample()
}
}
}
}
}
@Composable
fun ToastExample() {
val context = LocalContext.current
Button(onClick = { Toast.makeText(context,"This a simple toast tutorial!", Toast.LENGTH_LONG).show() }) {
Text("Click here to show toast!")
}
}
@Preview(showBackground = true)
@Composable
fun DefaultPreview() {
MyApplicationTheme {
ToastExample()
}
}I hope this Jetpack Compose tutorial is helpful for you.
