IME (Input Method Action) Action Button

In the below image, you can see the different types of actions that can be displayed in the IME Action Button on the Soft Keyboard.

So in this article, we will show you how you could implement IME Action Buttons in Soft Keyboard in Android using Jetpack Compose. Follow the below steps once the IDE is ready.

Step by Step Implementation

Step 1: Create a New Project in Android Studio

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. While choosing the template, select Empty Compose Activity. If you do not find this template, try upgrading the Android Studio to the latest version. We demonstrated the application in Kotlin, so make sure you select Kotlin as the primary language while creating a New Project.

Step 2: Working with the MainActivity.kt file

Go to the MainActivity.kt file and refer to the following code. Below is the code for the MainActivity.kt file. Comments are added inside the code to understand the code in more detail.

Kotlin




package com.geeksforgeeks.jcimeactions
  
import android.os.Bundle
import androidx.activity.ComponentActivity
import androidx.activity.compose.setContent
import androidx.compose.foundation.layout.Arrangement
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.foundation.text.KeyboardOptions
import androidx.compose.material.*
import androidx.compose.runtime.*
import androidx.compose.runtime.saveable.rememberSaveable
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.graphics.Color
import androidx.compose.ui.text.input.ImeAction
import androidx.compose.ui.tooling.preview.Preview
import com.geeksforgeeks.jcimeactions.ui.theme.JCImeActionsTheme
  
class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            // Calling the composable function to
            // display element and its contents
            MainContent()
        }
    }
}
  
// Creating a composable 
// function to display Top Bar
@Composable
fun MainContent() {
    Scaffold(
        topBar = { TopAppBar(title = { Text("GFG | IME Actions", color = Color.White) }, backgroundColor = Color(0xff0f9d58)) },
        content = { MyContent() }
    )
}
  
// Creating a composable function
// to create a TextField
// Calling this function as content
// in the above function
@Composable
fun MyContent(){
  
    // declaring a string variable to 
    // store the TextField input value
    var mInput by remember { mutableStateOf("") }
  
    Column(Modifier.fillMaxSize(), horizontalAlignment = Alignment.CenterHorizontally, verticalArrangement = Arrangement.Center) {
  
        // Creating a textField
        // setting keyboard options 
        // IME action as Done
        TextField(
            value = mInput,
            onValueChange = { mInput = it },
            label = { Text("Enter Input") },
            keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done)
        )
    }
}
  
// For displaying preview in the 
// Android Studio IDE emulator
@Preview(showBackground = true)
@Composable
fun DefaultPreview() {
    MainContent()
}


Output:

You can see that we are able to change the IME Action Button on the soft-keyboard to Done.
