FlexibleAlertDialog

FlexibleAlertDialog is an easily customizable, flexible Android Library, that helps you to show Alert Dialog inside any View (FrameLayout) not just in fullscreen.

Getting Started

Installing

Step 1. Add it in your root build.gradle at the end of repositories:

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

OR In Android Studio Bumblebee (2021.1.1) version add it settings.gradle.

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

Step 2. Add the dependency

dependencies {
    implementation 'com.github.hasanaga:FlexibleAlertDialog:0.0.2'
}

Usage

After importing the library you can use FlexibleAlertDialog to show alert dialog.

Add the FrameLayout where you want to display the Alert Dialog.

<FrameLayout
    android:id="@+id/frame_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Sample 1. Simple Alert Dialog with single message and buttons.

FlexibleAlertDialog.Builder(requireContext())
    .setTitle("Title")
    .setMessage("Message")
    .setParent(R.id.frame_layout)
    .setFragmentManager(childFragmentManager)
    .setNegativeButton {
        it.dismiss()
    }
    .setPositiveButton {
        it.dismiss()
    }
    .show()

Sample 2. Alert Dialog with custom view and operation.

Create R.layout.uppercase_layout.

FlexibleAlertDialog.Builder(requireContext())
    .setTitle("Make Uppercase")
    .setParent(R.id.frame_layout)
    .setFragmentManager(childFragmentManager)
    .setView(R.layout.uppercase_layout)
    .setPositiveButton {
        it.dismiss()
    }
    .setEvent {
    
        onCreate = {
        }

        onCreateView = { view ->
        }

        onPause = {
        }
        onDestroy = {
        }

        onResume = {
        }
        
        onClickButton = { buttonType, view ->

            if(buttonType == FlexibleAlertDialog.ButtonType.PositiveButton){

                view?.findViewById<EditText>(R.id.edit_text)?.text?.let {
                    resultTextView.text = it.toString().uppercase()
                }
            }
        }

    }
    .show()

Sample 3. Simple Calculator with custom view and operation. Create R.layout.custom_layout.

FlexibleAlertDialog.Builder(requireContext())
            .setTitle("Calculator with custom View")
            .setParent(R.id.frame_layout)
            .setFragmentManager(childFragmentManager)
            .setPositiveButton("Close") {
                it.dismiss()
            }
            .setView(R.layout.custom_layout)
            .setEvent {

                var lastResult = ""

                fun calculate(param1: String, param2: String, operation: Char): String {

                    if (param1.isEmpty() || param2.isEmpty()) return "Invalid params";

                    val intParam1: Int = try {
                        param1.toInt()
                    } catch (e: NumberFormatException) {
                        return "Invalid Param1"
                    }
                    val intParam2: Int = try {
                        param2.toInt()
                    } catch (e: NumberFormatException) {
                        return "Invalid Param2"
                    }

                    return when (operation) {
                        '+' -> "${intParam1.toFloat() + intParam2}"
                        '-' -> "${intParam1.toFloat() - intParam2}"
                        '*' -> "${intParam1.toFloat() * intParam2}"
                        '/' -> "${if (intParam2 == 0) 0F else intParam1.toFloat() / intParam2}"
                        else -> ""
                    }
                }

                onCreateView = {

                    val num1: EditText = it.findViewById(R.id.number1);
                    val num2: EditText = it.findViewById(R.id.number2);
                    val result: TextView = it.findViewById(R.id.result);

                    it.findViewById<Button>(R.id.addition).setOnClickListener {
                        lastResult = calculate(num1.text.toString(), num2.text.toString(), '+')
                        result.text = lastResult
                    }

                    it.findViewById<Button>(R.id.subtraction).setOnClickListener {
                        lastResult = calculate(num1.text.toString(), num2.text.toString(), '-')
                        result.text = lastResult
                    }

                    it.findViewById<Button>(R.id.division).setOnClickListener {
                        lastResult = calculate(num1.text.toString(), num2.text.toString(), '/')
                        result.text = lastResult
                    }

                    it.findViewById<Button>(R.id.multiplication).setOnClickListener {
                        lastResult = calculate(num1.text.toString(), num2.text.toString(), '*')
                        result.text = lastResult
                    }

                }

                onClickButton = { buttonType, _ ->

                    if (buttonType == FlexibleAlertDialog.ButtonType.PositiveButton) {
                        resultTextView.text = lastResult
                    }
                }


            }
            .show()
