1. Add the required dependencies to your project's build.gradle
file:
In root Project gradle file
buildFeatures {
compose true
}
In app module gradle file
dependencies {
implementation 'androidx.core:core-ktx:1.7.0'
implementation 'androidx.compose.ui:ui:1.0.4'
implementation 'androidx.compose.material:material:1.2.1'
implementation 'androidx.compose.ui:ui-tooling:1.0.4'
}
2. Create a new Composable function in your activity or fragment
package com.rajeshvijayakumr.jetpackcompose
import android.os.Bundle
import androidx.activity.ComponentActivity
import androidx.activity.compose.setContent
import androidx.compose.foundation.layout.*
import androidx.compose.foundation.lazy.LazyColumn
import androidx.compose.foundation.lazy.items
import androidx.compose.material3.Text
import androidx.compose.runtime.Composable
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp
class ListViewActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val items = listOf("Item 1", "Item 2", "Item 3","Item 4", "Item 5",
"Item 6","Item 7", "Item 8", "Item 9")
setContent {
MyScreen(items)
}
}
}
@Composable
fun MyScreen(items: List<String>) {
LazyColumn {
items(items) { item ->
ListItem(item = item)
}
}
}
@Composable
fun ListItem(item: String) {
Column(
modifier = Modifier
.padding(16.dp)
.fillMaxWidth()
) {
Text(text = item)
// Add other custom content for each item
}
}
In the above example, MyScreen
is a composable that takes a list of items and creates a LazyColumn
with items
to iterate over the list. For each item, it calls the ListItem
composable, passing the item as a parameter.
ListItem
is a custom composable that represents each item in the list. You can define the content and layout for each item inside this composable. In this example, it's a Column
with a Text
component displaying the item's text. You can add additional custom content for each item as needed.
In the MainActivity
, the list of items is provided to the MyScreen
composable, which sets the content view of the activity using setContent
.
When you run the app, you should see a list of items displayed vertically, and you can customize the content and layout of each item in the ListItem
composable based on your requirements.
