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:20.4.8'
      implementation 'com.github.TutorialsAndroid:progressx:v6.0.19' //required for kalertdialog lib
}

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")
    .setTitleTextGravity(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();

A error message：

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 this
    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

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

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 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();
