How to create material dialog Fragment?

MaterialDialogFragments

Common dialog fragments based on https://github.com/afollestad/material-dialogs

Features

• handles fragments save/restore states for you automatically
• includes mechanism to handle dialog events (even after screen restoration) inside activity and/or fragments
• includes some special dialogs (extracted in own modules) like e.g. a custom color dialog, text and number dialogs, multi text and number dialogs, a fast adapter recycler view dialog, an ads dialog - maybe even more to come
• also supports to show dialogs as dialog or bottom sheet
• easily extendable - create you own dialogs, simply check out the extension modules

Gradle (via JitPack.io)

1. add jitpack to your project s build.gradle:

repositories {

  maven {
 url "https://jitpack.io" 
}
 
}

2. add the implementation statement(s) to your module s build.gradle:

dependencies {
  	// -------- 	// core - DialogInfo, DialogList, DialogProgress 	// -------- 	 	implementation "com.github.MFlisar.MaterialDialogFragments:dialogs:<LATEST-VERSION>" 	 	// -------- 	// optional 	// -------- 	 	// input - DialogInput, DialogNumber, DialogNumberPicker 	implementation "com.github.MFlisar.MaterialDialogFragments:dialogs-input:<LATEST-VERSION>" 	 	// specials	 	implementation "com.github.MFlisar.MaterialDialogFragments:dialogs-datetime:<LATEST-VERSION>" 	implementation "com.github.MFlisar.MaterialDialogFragments:dialogs-fastadapter:<LATEST-VERSION>"	 	implementation "com.github.MFlisar.MaterialDialogFragments:dialogs-color:<LATEST-VERSION>" 	implementation "com.github.MFlisar.MaterialDialogFragments:dialogs-frequency:<LATEST-VERSION>" 	implementation "com.github.MFlisar.MaterialDialogFragments:dialogs-ads:<LATEST-VERSION>"  	// -------- 	// alternatively, to include ALL modules at once 	// -------- 	 	// implementation  com.github.MFlisar:MaterialDialogFragments:<LATEST-VERSION>  
}

Usage

Usage is very simply, you only need to do following:

• Activities or Fragments using the dialog fragments must implement the simple DialogFragmentCallback interface:

    interface DialogFragmentCallback {
  
  	fun onDialogResultAvailable(event: BaseDialogEvent): Boolean
  
  }
   

• you create a dialog with the corresponding setup class like e.g.:

    DialogInfo(
  	1, // ID - this allows you to identify dialog events in the callback
  	"Info Title".asText(),
  	"Some info label".asText()
  )
  		.create()
  		.show(this) 

• in the DialogFragmentCallback you can handle the result now like following:

    override fun onDialogResultAvailable(event: BaseDialogEvent): Boolean {
  
   return when (event) {
  
  		is DialogInfoEvent -> {
  
  			Toast.makeText(this, "Info dialog closed - ID = ${
  event.id
  }
  ", Toast.LENGTH_SHORT).show()
  			true
  		
  }
   else false
  	
  }
  
  }
   

That s all. Optionally you can set up some global settings like following, preferably in your application class once only:

DialogSetup.SEND_CANCEL_EVENT_BY_DEFAULT = true 

The DialogSetup offers some other settings as well.
