Progress indicators are very useful UI elements to show the progress of any kind of action. In this blog post, let’s learn how to add a circular progress indicator in Jetpack Compose.
CircularProgressIndicator composable helps to show circular progress indicators in Jetpack Compose. Following is the code snippet of the indeterminate circular progress indicator.
@Composable
fun ProgressIndicator(){
Column{
CircularProgressIndicator(
modifier = Modifier
.size(100.dp),
color = Color.Red,
strokeWidth = 10.dp
)
}
}You can also make the progress indicator determinate using the progress parameter.
Following is the complete code.
package com.example.example
import android.os.Bundle
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.graphics.Color
import androidx.compose.ui.tooling.preview.Preview
import androidx.compose.ui.unit.dp
import com.example.example.ui.theme.ExampleTheme
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
ExampleTheme {
// A surface container using the 'background' color from the theme
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colors.background
) {
ProgressIndicator()
}
}
}
}
}
@Preview(showBackground = true)
@Composable
fun ProgressIndicator(){
Column{
CircularProgressIndicator(
modifier = Modifier
.size(100.dp),
color = Color.Red,
strokeWidth = 10.dp
)
}
}
@Preview(showBackground = true)
@Composable
fun DefaultPreview() {
ExampleTheme {
ProgressIndicator()
}
}Following is the output.
That’s how you add a circular progress indicator in Jetpack Compose.
