Pull-to-refresh functionality is commonly used in Android applications to enhance the user experience. It allows users to refresh content by simply pulling down on the screen. Implementing pull-to-refresh with Android Jetpack Compose is straightforward. In this article, you’ll learn how to add this feature to your Android app step by step.

Compose is a powerful tool for building user interfaces, and adding pull-to-refresh functionality is easy. Here are the steps to implement it:

First, you need to add the material library to your project. This library contains you to quickly implement pull-to-refresh functionality. To complete this step, add the necessary dependency to your project’s build.gradle file. I also used faker in order to show random data while pulling refresh.

dependencies {
    // Other dependencies
    implementation("androidx.compose.material:material:1.5.1")
    implementation("io.github.serpro69:kotlin-faker:1.15.0-rc.1")
}
@OptIn(ExperimentalMaterialApi::class)
    @Composable
    fun PullRefresh() {
        val faker = Faker()
        val refreshScope = rememberCoroutineScope()
        var refreshing by remember { mutableStateOf(false) }

        fun refresh() = refreshScope.launch {
            refreshing = true
            delay(1000)
            refreshing = false
        }

        val state = rememberPullRefreshState(refreshing, ::refresh)

        Box(Modifier.pullRefresh(state)) {
            LazyColumn(Modifier.fillMaxSize()) {
                if (!refreshing) {
                    items(100) {
                       Text(
                           modifier = Modifier
                               .padding(10.dp),
                           text = faker.name.name(),
                       )
                    }
                }
            }

            PullRefreshIndicator(refreshing, state, Modifier.align(Alignment.TopCenter))
        }
    }


As can be seen, it is quite easy to use. Here, while refreshing, you can reissue your API requests. For more information click here
