ScreenShot

Setup

The simplest way to use AlertDialog is to add the library as dependency to your build.

Gradle

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

allprojects {
	repositories {
		...
        mavenCentral()
		maven { url 'https://jitpack.io' }
	}
}

Step 2. On your root build.gradle, add mavenCentral() to the allprojects section. On your module build.gradle, add

dependencies {
      implementation 'io.github.tutorialsandroid:kalertdialog:20.6.15'
      implementation 'io.github.tutorialsandroid:progressx:7.0.5' //required for kalertdialog lib
}

⚠️ Important: compileSdk Requirement

Starting from the latest versions of KAlertDialog and ProgressX, this library is built with the latest Android SDK.

If you are using:

implementation 'io.github.tutorialsandroid:kalertdialog:20.6.15'
implementation 'io.github.tutorialsandroid:progressx:7.0.5'

your app must compile against Android API 37 or higher.

Required configuration

In your app-level build.gradle, make sure your compileSdk is set to 37 or higher:

android {
    compileSdk 37

    defaultConfig {
        minSdk 23
        targetSdk 36
    }
}

For Kotlin DSL:

android {
    compileSdk = 37

    defaultConfig {
        minSdk = 23
        targetSdk = 36
    }
}

Why is this required?

If your project is using an older compileSdk, for example:

compileSdk 36

you may see an error like this:

Dependency 'io.github.tutorialsandroid:kalertdialog:20.6.15' requires libraries and applications
that depend on it to compile against version 37 or later of the Android APIs.

:app is currently compiled against android-36.1.

This happens because the latest version of KAlertDialog and ProgressX is compiled with Android API 37.

Important note

Updating compileSdk is safe and different from updating targetSdk or minSdk.

• compileSdk allows your app to compile with the latest Android APIs.
• targetSdk controls which Android runtime behavior changes your app opts into.
• minSdk controls the minimum Android version your app can be installed on.

So you can update only compileSdk to 37 while keeping your existing targetSdk and minSdk.

Solution

Update your app-level Gradle file:

android {
    compileSdk 37
}

Then sync the project again in Android Studio.

If Android Studio asks to install Android API 37, install it from:

Tools > SDK Manager > Android SDK

After updating compileSdk, the AAR metadata error should be resolved.

Usage

Show material progress

KAlertDialog pDialog = new KAlertDialog(this, KAlertDialog.PROGRESS_TYPE);
pDialog.getProgressHelper().setBarColor(Color.parseColor("#A5DC86"));
pDialog.setTitleText("Loading");
pDialog.setCancelable(false);
pDialog.show();

You can customize progress bar dynamically with materialish-progress methods via KAlertDialog.getProgressHelper():

• resetCount()
• isSpinning()
• spin()
• stopSpinning()
• getProgress()
• setProgress(float progress)
• setInstantProgress(float progress)
• getCircleRadius()
• setCircleRadius(int circleRadius)
• getBarWidth()
• setBarWidth(int barWidth)
• getBarColor()
• setBarColor(int barColor)
• getRimWidth()
• setRimWidth(int rimWidth)
• getRimColor()
• setRimColor(int rimColor)
• getSpinSpeed()
• setSpinSpeed(float spinSpeed)

A basic message：

new KAlertDialog(this)
    .setTitleText("Here's a message!")
    .show();

A title with a text under：

new KAlertDialog(this)
    .setTitleText("Here's a message!")
    .setContentText("It's pretty, isn't it?")
    .show();

A title with gravity changed：

new KAlertDialog(this, KAlertDialog.NORMAL_TYPE)
    .setTitleText("Lorem Ipsum")
    .setTitleTextLayoutGravity(Gravity.START); //you can specify your own gravity
    .setContentText("Lorem Ipsum is simply dummy text of the printing and typesetting industry.")
    .setConfirmClickListener("OK", null)
    .show();

new KAlertDialog(this, KAlertDialog.ERROR_TYPE)
    .setTitleText("Oops...")
    .setContentText("Something went wrong!")
    .show();

A warning message：

new KAlertDialog(this, KAlertDialog.WARNING_TYPE)
    .setTitleText("Are you sure?")
    .setContentText("Won't be able to recover this file!")
    .setConfirmClickListener("Yes,delete it!", null)
    .show();

A success message：

new KAlertDialog(this, KAlertDialog.SUCCESS_TYPE)
    .setTitleText("Good job!")
    .setContentText("You clicked the button!")
    .show();

A message with a custom icon：

new KAlertDialog(this, KAlertDialog.CUSTOM_IMAGE_TYPE)
    .setTitleText("Sweet!")
    .setContentText("Here's a custom image.")
    .setCustomImage(R.drawable.custom_img)
    .show();

A message with a custom vector drawable with tint option in dark mode:

new KAlertDialog(this, KAlertDialog.CUSTOM_IMAGE_TYPE)
    .setTitleText("Sweet!")
    .setContentText("Here's a custom image.")
    .setCustomImage(R.drawable.vector_drawable)
    .setDrawableTintOnNightMode(true, R.color.red) //it will work only if your app is running in night mode
    .show();

A message with a custom image URL

displayType - KAlertDialog.IMAGE_BIG - For full size image
displayType - KAlertDialog.IMAGE_CIRCLE - For Circle Crop image

Note: This feature is still in development

new KAlertDialog(this, KAlertDialog.URL_IMAGE_TYPE)
                .setTitleText("KAlertDialog")
                .setContentText("Here's a custom image.")
                .setURLImage("put your image url", displayType)
                .setConfirmClickListener("OK", null)
                .show();

A dialog with input-field

KAlertDialog dialog = new KAlertDialog(this, KAlertDialog.INPUT_TYPE);
dialog.setInputFieldHint("Write message");
dialog.setInputFieldText("Hello World!"); //If you want to set default text in input field
dialog.setTitleText("Edit Text");
dialog.setConfirmClickListener("OK", kAlertDialog -> {
    kAlertDialog.dismissWithAnimation();
    kAlertDialog.getInputText(); //you get the input text by calling thi`s
    Toast.makeText(this, kAlertDialog.getInputText(), Toast.LENGTH_SHORT).show();
});
dialog.show();
//below this line is necessary to show keyboard when using input-field
dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
        |WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM); //this will allow to show keyboard

Custom drawable to confirm button and cancel button (*NEW UPDATED 19-05-2026)

  new KAlertDialog(this, KAlertDialog.NORMAL_TYPE, true)
   .setTitleText("Lorem Ipsum")
   .setContentText("Lorem Ipsum is simply dummy text of the printing and typesetting industry.")
   .setConfirmClickListener("OK", null)
   .setCancelClickListener("Cancel", null)
   .confirmButtonDrawable(R.drawable.red_button_background)
   .cancelButtonDrawable(R.drawable.button_background)
   .show();

To Hide Cancel And Confirm Button：

new KAlertDialog(this, KAlertDialog.CUSTOM_IMAGE_TYPE)
    .setTitleText("Sweet!")
    .setContentText("Here's a custom image.")
    .setCustomImage(R.drawable.custom_img)
    .showConfirmButton(false) //to hide the confirm button set it to false
    .showCancelButton(false) //to hide the cancel button set it to false
    .show();

To Change the font of only title：

To apply custom downloaded fonts you have place your font file in "assest/fonts" folder or under "res/font" folder. Below 
is the screen-shot for reference about how to place your font file in assest folder

new KAlertDialog(this, KAlertDialog.NORMAL_TYPE)
    .setTitleText("Lorem Ipsum")
    .setTitleFontAssets("fonts/os.ttf")
    .setContentText("Lorem Ipsum is simply dummy text of the printing and typesetting industry.")
    .setConfirmClickListener("OK", null)
    .show();

To Change the font of only content：

To apply custom downloaded fonts you have place your font file in "assest/fonts" folder or under "res/font" folder. Below 
is the screen-shot for reference about how to place your font file in assest folder

kAlertDialog.setContentFontAssets("fonts/poppins_regular.ttf");

You can also have font in the res/font folder and apply directly.

new KAlertDialog(this, KAlertDialog.NORMAL_TYPE)
    .setTitleText("Lorem Ipsum")
    .setContentText("Lorem Ipsum is simply dummy text of the printing and typesetting industry.")
    .setContentFont(R.font.sf)
    .setConfirmClickListener("OK", null)
    .show();

To Change the color of title and content

.setTitleColor(R.color.yourColorName)
.setContentColor(R.color.yourColorName)

To Change the font weight of title and content

.setTitleFontWeight(Typeface.BOLD)
.setContentFontWeight(Typeface.ITALIC)

To Change the content textAlignment

//Text alignment start
.setContentTextAlignment(View.TEXT_ALIGNMENT_VIEW_START, Gravity.START)

or

//Text alignment center
.setContentTextAlignment(View.TEXT_ALIGNMENT_CENTER, Gravity.CENTER)    

Bind the listener to confirm button：

new KAlertDialog(this, KAlertDialog.WARNING_TYPE, 0)
    .setTitleText("Are you sure?")
    .setContentText("Won't be able to recover this file!")
    .setConfirmClickListener("Yes,delete it!",new KAlertDialog.KAlertClickListener() {
        @Override
        public void onClick(KAlertDialog sDialog) {
            sDialog.dismissWithAnimation();
        }
    })
    .show();

Show the cancel button and bind listener to it：

new KAlertDialog(this, KAlertDialog.WARNING_TYPE, 0)
    .setTitleText("Are you sure?")
    .setContentText("Won't be able to recover this file!")
    .setConfirmClickListener("Yes,delete it!", null)
    .showCancelButton(true)
    .setCancelClickListener("No,cancel plx!", new KAlertDialog.KAlertClickListener() {
        @Override
        public void onClick(KAlertDialog sDialog) {
            sDialog.cancel();
        }
    })
    .show();

Customizing the alert dialog

//if your app is night mode then you can tint your vector drawable to specific color you want
.setDrawableTintOnNightMode(true, R.color.white)

// you can change the color of confirm button
.confirmButtonColor(R.color.colorPrimary)

// you can change the color of cancel button
.cancelButtonColor(R.color.colorAccent) 

//you can change the color of button text
.setConfirmClickListener("OK", R.color.black, clickListener) 

//you can change the color of button text 
.setCancelClickListener("CANCEL", R.color.black, clickListener)

// you can change the content text size
.setContentTextSize(50) 

//you can use html in title text and same in content text
.setTitleText("<h2>Title</h2><br><p>Description here</p>")

And if you want to change the button corners with color create a drawable file

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_pressed="true">
            <shape android:shape="rectangle">
                <solid android:color="#FF5474" />
                <corners android:radius="6dp"/>
            </shape>
        </item>
        <item>
            <shape android:shape="rectangle">
                <solid android:color="#FF1744" />
                <corners android:radius="6dp"/>
            </shape>
        </item>
    </selector>

And then call this method when you create drawable

  .confirmButtonColor(R.drawable.button_background) // you can change border and color of button

And if you want to hide Title Text and Content Text of alert dialog

.setTitleText("Are you sure?") //just don't write this line if you want to hide title text
.setContentText("Won't be able to recover this file!") // don't write this line if you want to hide content text

And if you want to hide Title Text and Content Text on alert type change

new KAlertDialog(this, KAlertDialog.WARNING_TYPE)
    .setTitleText("Are you sure?")
    .setContentText("Won't be able to recover this file!")
    .showCancelButton(true)
    .setCancelClickListener("No,cancel plx!", sDialog -> 
        sDialog.setTitleText(null)
            .setContentText("Your imaginary file is safe :)")
            .showCancelButton(false)
            .setConfirmClickListener("OK", null)
            .changeAlertType(KAlertDialog.ERROR_TYPE))
    .setConfirmClickListener("Yes,delete it!",sDialog -> 
        sDialog.setTitleText("Deleted!")
            .showCancelButton(false)
            .setContentText(null)
            .setConfirmClickListener("OK",null)
            .changeAlertType(KAlertDialog.SUCCESS_TYPE))
    .show();

Change the dialog style upon confirming：

new KAlertDialog(this, KAlertDialog.WARNING_TYPE, 0)
    .setTitleText("Are you sure?")
    .setContentText("Won't be able to recover this file!")
    .setConfirmText("Yes,delete it!")
    .setConfirmClickListener(new KAlertDialog.KAlertClickListener() {
        @Override
        public void onClick(KAlertDialog sDialog) {
            sDialog
                .setTitleText("Deleted!")
                .setContentText("Your imaginary file has been deleted!")
                .setConfirmClickListener("OK", null)
                .changeAlertType(KAlertDialog.SUCCESS_TYPE);
        }
    })
    .show();
