I will also stream sometimes when developing at https://www.twitch.tv/tomgrill and write a blog article from time to time at http://tomgrill.de

Version

Current stable: 1.3.0 (Snapshot versions are no longer provided)

##Supported Platforms Android, iOS, iOS-MOE, Desktop (kinda) Desktop show Java UI Dialogs which usually dont fit very well in desktop game. I added Desktop support mainly to make testing while developing easier.

##Requirements libGDX 1.9.3+, Android API 9+, ios 6+, ios-moe 9+

##Currently available dialog types

ButtonDialog: shows a dialog with 1-3 buttons for the user to click.
ProgressDialog: Shows dialog with a progress wheel. Not cancelable by the user.
TextPrompt: On screen display with text input.

Installation

Core

Add this to your build.gradle core dependencies

compile "de.tomgrill.gdxdialogs:gdx-dialogs-core:1.3.0"

Android

Add this to your build.gradle android dependencies

compile "de.tomgrill.gdxdialogs:gdx-dialogs-android:1.3.0"

Copy the /gdx-dialogs-android/res folder from this project to your android project. Keep the directory structure.

You can edit the /gdx-dialogs-android/res/values-v11/styles.xml if you want use another theme like Holo.Light

If your project already has styles.xml file make sure you merge what you need from both files.

iOS

Add this to your robovm.xml

<forceLinkClasses>
    ....
    <pattern>de.tomgrill.gdxdialogs.ios.IOSGDXDialogs</pattern>
</forceLinkClasses>

Add this to your build.gradle ios dependencies

compile "de.tomgrill.gdxdialogs:gdx-dialogs-ios:1.3.0"

iOS-MOE

Add this to your build.gradle ios-moe dependencies

compile "de.tomgrill.gdxdialogs:gdx-dialogs-ios-moe:1.3.0"

Desktop

Add this to your build.gradle desktop dependencies

compile "de.tomgrill.gdxdialogs:gdx-dialogs-desktop:1.3.0"

HTML(GWT)

Add this to your build.gradle html dependencies

compile "de.tomgrill.gdxdialogs:gdx-dialogs-html:1.3.0"
compile "de.tomgrill.gdxdialogs:gdx-dialogs-core:1.3.0:sources"
compile "de.tomgrill.gdxdialogs:gdx-dialogs-html:1.3.0:sources"

Add this to your GdxDefinition.gwt.xml

<inherits name='de.tomgrill.gdxdialogs.html.gdx_dialogs_html' />
<inherits name="de.tomgrill.gdxdialogs.core.gdx_dialogs_core" />

Usage

View the gdx-dialogs sample app https://github.com/TomGrill/gdx-dialogs-app

Enable

GDXDialogs dialogs = GDXDialogsSystem.install();

ButtonDialog

GDXButtonDialog bDialog = dialogs.newDialog(GDXButtonDialog.class);
bDialog.setTitle("Buy a item");
bDialog.setMessage("Do you want to buy the mozarella?");

bDialog.setClickListener(new ButtonClickListener() {

	@Override
	public void click(int button) {
		// handle button click here
	}
});

bDialog.addButton("No");
bDialog.addButton("Never");
bDialog.addButton("Yes, nomnom!");

bDialog.build().show();

ProgressDialog

GDXProgressDialog progressDialog = dialogs.newDialog(GDXProgressDialog.class);

progressDialog.setTitle("Download");
progressDialog.setMessage("Loading new level from server...");

progressDialog.build().show();

TextPrompt

GDXTextPrompt textPrompt = dialogs.newDialog(GDXTextPrompt.class);

textPrompt.setTitle("Your name");
textPrompt.setMessage("Please tell me your name.");

textPrompt.setCancelButtonLabel("Cancel");
textPrompt.setConfirmButtonLabel("Save name");

textPrompt.setTextPromptListener(new TextPromptListener() {

	@Override
	public void confirm(String text) {
	  // do something with the user input
	}

	@Override
	public void cancel() {
	  // handle input cancel
	}
});

textPrompt.build().show();

Open GL Context

Sometimes you want to call a method within one of your listeners which requires OpenGL context from the libgdx main thread. Since all dialogs run in their own thread (without OpenGL context) you have to make sure your method runs in the main thread by wrapping as postRunnable:

dialog.setClickListener(new ButtonClickListener() {
    @Override
    public void click(int button) {
        Gdx.app.postRunnable(new Runnable() {
            @Override
            public void run() {
                // call the a method which requires OpenGL context.
            }
        });
    }
});

Create your own dialogs.

In case you require are certain dialog (F.e. DatePicker, ProgressBar, ....) which is not supported by gdx-dialogs yet you can write your own dialog.

Create a interface like this (in core project): GDXButtonDialog
Create the implementation for Android like this (in android project): AndroidGDXButtonDialog
Create the implementation for Desktop like this (in desktop project): DesktopGDXButtonDialog
Create the implementation for iOS like this (in ios project): IOSGDXButtonDialog
Create a fallback implementation with empty methods (in core project): FallbackGDXButtonDialog

If your dialog is written register it like this:

if(Gdx.app.getType() == ApplicationType.Android) {
	dialogs.registerDialog("package.for.your.dialog.interface.GDXButtonDialog", "package.for.your.dialog.os.specific.implementation.AndroidGDXButtonDialog");
}

else if(Gdx.app.getType() == ApplicationType.Desktop) {
	dialogs.registerDialog("package.for.your.dialog.interface.GDXButtonDialog", "package.for.your.dialog.os.specific.implementation.DesktopGDXButtonDialog");
}

else if(Gdx.app.getType() == ApplicationType.iOS) {
	dialogs.registerDialog("package.for.your.dialog.interface.GDXButtonDialog", "package.for.your.dialog.os.specific.implementation.IOSGDXButtonDialog");
}

else {
	dialogs.registerDialog("package.for.your.dialog.interface.GDXButtonDialog", "package.for.your.dialog.os.specific.implementation.FallbackGDXButtonDialog");
}

Use your own dialog:

dialogs.newDialog(GDXButtonDialog.class); // Use your dialog interface here

Note: Every platform specific implementation must have constructor even if it is empty. Android implementations must have a contructor accepting Activity parameter.

Increase your karma points :) Share your dialog with us, add it to this repository and make a Pull Request.
