Android-Prompter

Android library that facilitates input validation

Simple wrap your view with

Prompter.showWithClick(yourView, supportFragmentManager)

and enjoy nice UX flow

All properties like inputType, hint/text, message or title will be taken from yourView or you can specify them manualy with

Prompter.showWithClick(etPage, supportFragmentManager)
        .title("Jump to page")
        .message("Enter page you would like to jump to")
        .inputType(InputType.TYPE_CLASS_NUMBER)
        .showValue { book.currentPosition.toString() } 
        .hintMode() //Current value will be displayed as hint
        .validate("Please enter page in range of [1, ${book.size}]"){ it.toInt() in 1..book.size }

By default empty values won’t pass validation process but you can change this with .allowEmpty()

You can even customize whole callback method (callbacks are called only when validation pass or is not specified)

Prompter.showWithClick(etPage, supportFragmentManager)
        .setOnValueChangeListener {
            if (it.toInt() in 0..100)
                etPage.setText(newInt.toString())
        }

It’s worth to mention that setOnValueChangeListener overrides all listeners whereas addOnValueChangeListener appends to current list of listeners.
So:

Prompter.showWithClick(etDouble, supportFragmentManager)
        .addOnValueChangeListener {
            Log.d(TAG, "A")
        }
        .addOnValueChangeListener {
            Log.d(TAG, "B")
        }
        .setOnValueChangeListener {
            Log.d(TAG, "C")
        }

will print only
D/Prompter: C

Sometimes you may want specify different View that prompt the dialog. In this case use Prompter.on() and trigger manually .show()

val prompter = Prompter.on(tvPage, supportFragmentManager)
        .title("Jump to page")
        .validate("Please enter page in range of [1, ${book.size}]") {
            it.toInt() in 1..book.size
        }
button1.setOnClickListener { prompter.show() }
button2.setOnClickListener { prompter.show() }
button3.setOnClickListener { prompter.show() }
container.setOnClickListener { prompter.show() }
