Alerter - An Android Alerter Library, now in Jetpack Compose!

This library aims to overcome the limitations of Toasts and Snackbars, while reducing the complexity of your layouts.

This library originated from Tapado Alerter and modified to make proper usage for Jetpack Compose.

General

With simplicity in mind, the Alerter employs the builder pattern to facilitate easy integration into any app. A customisable Alert View is dynamically added to the Decor View of the Window, overlaying all content.

Install

Include the JitPack.io Maven repo in your project's build.gradle file

allprojects {
 repositories {
    maven { url "https://jitpack.io" }
 }
}

Then add this dependency to your app's build.gradle file

dependencies {
    implementation 'com.github.akardas16:Alerter:1.0.6'
}

Usage

Basic Usage

 var showAlert by remember { mutableStateOf(false) }

 Alerter(isShown = showAlert, onChanged = {showAlert = it}) {

                //Your Custom Content

            }

• Use modifier = Modifier.iconPulse() for icon pulse effect

Alerter with icon, title and message

 var showAlert by remember { mutableStateOf(false) }

 Alerter(isShown = showAlert, onChanged = {showAlert = it},
                backgroundColor = Color(0xFFF69346)) {
                Row(modifier = Modifier
                    .fillMaxWidth()
                    .fillMaxHeight(),
                    horizontalArrangement = Arrangement.Start,
                    verticalAlignment = Alignment.CenterVertically) {

                    Icon(imageVector = Icons.Rounded.Notifications, contentDescription = "",
                        tint = Color.White, modifier = Modifier.padding(start = 12.dp).iconPulse())

                    Column(modifier = Modifier.padding(horizontal = 12.dp)) {
                        Text(text = "Alert Title", color = Color.White, fontWeight = FontWeight.SemiBold, fontSize = 16.sp)
                        Text(text = "Alert text...", color = Color.White, fontSize = 14.sp)

                    }
                }
            }

• backgroundColor = Color.Transparent will seperate UI from status bar.
• By default value is backgroundColor = Color.Transparent (see below example)

Alerter with Coil image library

 var showAlert by remember { mutableStateOf(false) }

 Alerter(isShown = showAlert, onChanged = { showAlert = it }, backgroundColor = Color.Transparent) {

                Row(modifier = Modifier.fillMaxWidth().fillMaxHeight()
                        .background(Color(0xFFE2E1E1),shape = RoundedCornerShape(15.dp))
                        .padding(vertical = 16.dp),
                    horizontalArrangement = Arrangement.Start, verticalAlignment = Alignment.CenterVertically) {

                    //Coil
                    AsyncImage(model = "image url",
                        contentDescription = "person", contentScale = ContentScale.Crop,
                        modifier = Modifier.padding(start = 24.dp)
                            .size(48.dp).clip(CircleShape))

                    Column(modifier = Modifier.padding(horizontal = 12.dp)) {

                        Text(text = "Jane Clark",
                            color = Color.Black.copy(0.7f), fontWeight = FontWeight.SemiBold)

                        Text(text = "You have new message",
                            color = Color.Black.copy(0.7f), fontSize = 14.sp)

                    }

                }
            }

 var showAlert by remember { mutableStateOf(false) }

 Alerter(isShown = showAlert, onChanged = {showAlert = it}, backgroundColor = Color.Transparent) {

                Row(modifier = Modifier.fillMaxWidth().fillMaxHeight()
                    .background(Color(0xFF9499FF), shape = RoundedCornerShape(18.dp))
                    .padding(vertical = 16.dp),
                    horizontalArrangement = Arrangement.Start, verticalAlignment = Alignment.CenterVertically) {

                    Icon(painter = painterResource(id = R.drawable.gift_icon), contentDescription = "",
                        tint = Color.Unspecified, modifier = Modifier.padding(start = 24.dp).size(48.dp))

                    Column(modifier = Modifier.padding(horizontal = 12.dp)) {
                        Text(text = "Gift", color = Color.White, fontWeight = FontWeight.SemiBold)
                        Text(text = "Claim your gift!", color = Color.White, fontSize = 14.sp)
                    }

                    Spacer(modifier = Modifier.weight(1f))
                    Button(onClick = { showAlert4 = !showAlert4 },
                        shape = RoundedCornerShape(8.dp), colors = ButtonDefaults.buttonColors(
                            containerColor = Color(0xFF4C52C7), contentColor = Color.White),
                        modifier = Modifier.padding(end = 24.dp)) {
                        Text(text = "Claim")
                    }
                }
            }
