AlertDialogDsl

A simple Kotlin DSL layer above AlertDialog.Builder

Add it to your project

Add JitPack in your root build.gradle at the end of repositories:

repositories {
    maven { url 'https://jitpack.io' }
}

Add the dependency:

dependencies {
    implementation 'com.github.datikaa:AlertDialogDsl:0.0.6'
}

Enjoy! 😉

Basic usage

For Activity and Fragment there are extension functions that will use the available Context object, so you don't have to provide it:

class SampleActivity : AppCompatActivity() {
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_sample)
        
        alertDialog { 
            title("Title goes here")
            message("Resources can be used too just like for the buttons")
            positiveButton("Yes") { dialogInterface, which ->
                Toast.makeText(this@SampleActivity, "Yes clicked", Toast.LENGTH_SHORT).show()
            }
            negativeButton("No")  { dialogInterface, which ->
                Toast.makeText(this@SampleActivity, "No clicked", Toast.LENGTH_SHORT).show()
            }
            show()
        }
    }
}

In case you want to use it elsewhere, you need to pass a Context object to a globally available function:

alertDialog(context) {
    title("Title goes here")
    message("Resources can be used too just like for the buttons")
    positiveButton(R.string.ok) { dialogInterface, which ->
        // handle your click event here for positive button
    }
    show()
}

All the AlertDialog.Builder functions are there, and there is also a Single/Multi choice item builder:

alertDialog {
    title("Title goes here")
    multiChoiceItems {
        item("Item 1", false)
        item("Item 2", false)
        item("Item 3", true)
        item("Item 4", false)
        onItemClick { dialogInterface, which, isChecked ->
            Toast.makeText(this@MainActivity, "${items[which].first} is ${if (isChecked) "checked." else "not checked."}", Toast.LENGTH_LONG).show()
        }
    }
    positiveButton("Accept") { dialogInterface, which ->
        Toast.makeText(this@MainActivity, "Selection accepted", Toast.LENGTH_LONG).show()
    }
    show()
}

Please note that the Dialog won't show automatically, you either have to call create() or show().
