Adding a button to activity

[NemesisMate]

This is a pure java understanding problem. You may look at the javadocs or the source itself. Just call that method on a button object with an action as parameter.
eg:

myButton.addClickCommands(ButtonAction.Click,
myCommand );

You have the method Button.addClickCommands(Command) too

Also, here’s most of Lemur’s glass style, written in Java:

public static void loadGlassStyle(Application app) {
GuiGlobals.initialize(app);

////

Styles styles = GuiGlobals.getInstance().getStyles();
Attributes attrs;

TbtQuadBackgroundComponent gradient = TbtQuadBackgroundComponent.create(
		app.getAssetManager().loadTexture("/com/simsilica/lemur/icons/bordered-gradient.png"),
		1f, 1, 1, 126, 126,
		1f, false);

TbtQuadBackgroundComponent bevel = TbtQuadBackgroundComponent.create(
		app.getAssetManager().loadTexture("/com/simsilica/lemur/icons/bevel-quad.png"),
		1f, 1, 1, 126, 126,
		1f, false);

TbtQuadBackgroundComponent border = TbtQuadBackgroundComponent.create(
		app.getAssetManager().loadTexture("/com/simsilica/lemur/icons/border.png"),
		1f, 1, 1, 126, 126,
		1f, false);

TbtQuadBackgroundComponent border2 = TbtQuadBackgroundComponent.create(
		app.getAssetManager().loadTexture("/com/simsilica/lemur/icons/border.png"),
		1f, 1, 1, 126, 126,
		1f, false);

QuadBackgroundComponent doubleGradient = new QuadBackgroundComponent(new ColorRGBA(.5f, .75f, .85f, .5f));
doubleGradient.setTexture(app.getAssetManager().loadTexture("/com/simsilica/lemur/icons/double-gradient-128.png"));

attrs = styles.getSelector("glass");
attrs.set("fontSize", 24);

attrs = styles.getSelector("label", "glass");
attrs.set("insets", new Insets3f(2, 2, 0, 2));
attrs.set("color", new ColorRGBA(0.5f, 0.75f, 0.75f, 0.85f));

attrs = styles.getSelector("container", "glass");
TbtQuadBackgroundComponent gradient_clone_container = gradient.clone();
gradient_clone_container.setColor(new ColorRGBA(.25f, .5f, .5f, .5f));
attrs.set("background", gradient_clone_container);

Command<Button> pressedCommand = new Command<Button>() {
	@Override
	public void execute(Button source) {
		if(source.isPressed()) {
			source.move(1, -1, 0);
		} else {
			source.move(-1, 1, 0);
		}
	}
};

Map<ButtonAction, List<Command<? super Button>>> stdButtonCommands = new HashMap<>();
List<Command<? super Button>> listButtonCommands = new ArrayList<>();
listButtonCommands.add(pressedCommand);
stdButtonCommands.put(ButtonAction.Down, listButtonCommands);
stdButtonCommands.put(ButtonAction.Up, listButtonCommands);

// selector( “title”, “glass” ) {
// color = color(0.8, 0.9, 1, 0.85f)
// highlightColor = color(1, 0.8, 1, 0.85f)
// shadowColor = color(0, 0, 0, 0.75f)
// shadowOffset = new com.jme3.math.Vector3f(2, -2, -1);
// background = new QuadBackgroundComponent( color(0.5, 0.75, 0.85, 0.5) );
// background.texture = texture( name:“/com/simsilica/lemur/icons/double-gradient-128.png”,
// generateMips:false )
// insets = new Insets3f( 2, 2, 2, 2 );
//
// buttonCommands = stdButtonCommands;
// }

attrs = styles.getSelector("title", "glass");

attrs = styles.getSelector("button", "glass");
TbtQuadBackgroundComponent gradient_clone_button = gradient.clone();
gradient_clone_button.setColor(new ColorRGBA(0, .75f, .75f, .5f));
attrs.set("background", gradient_clone_button);
attrs.set("color", new ColorRGBA(.8f, .9f, 1f, .85f));
attrs.set("insets", new Insets3f(2, 2, 2, 2));
attrs.set("buttonCommands", stdButtonCommands);

////

styles.setDefaultStyle("glass");

}

… I wrote this a while back ago, but it should work

Works! excellent. Thanks!

Now I have Lemur up & running and can start focusing on my application development.
Just one thing - Lemur & Lemur proto are generate some kind of duplicate file error which needs the following statement in the gradle file in order to resolve it:
packagingOptions {
exclude ‘com/simsilica/lemur/style/base/glass-styles.groovy’
}
It looks like a quick & dirty solution but it works…

[pspeed]

It’s not really a duplicate file… this is the other unfortunate thing about android with respect to Lemur’s built in styles.

In a normal Java application, these style files will all live in their separate jars. When loading the glass style, Lemur will look for all of them and run them all. This means that add-ons can extend the existing styles to include things for the new add on components.

Unfortunately, because I guess an android app collapses all of the jars, these show up as duplicates and ignoring the extra ones is basically breaking the style resources… which is ok because they don’t work anyway because they require groovy.

Something I will have to figure out if/when the groovy support starts working on android and/or someone figures out the magic incantations to make it work.

[adi.barda]

I’m not a Java expert and really don’t know what Groovy is but it looks like there is a support for Android since 2015

https://github.com/groovy/groovy-android-gradle-plugin

What do you say?

[pspeed]

I say “I don’t do android development” so I have no idea why others can’t get it working.

If someone figures it out then I’m sure a bunch of people would love to know it here. And then we can work on fixing the duplicate resource problem.

[adi.barda]

I’ll do my best to figure it out and when I succeed, I’ll post it here or make a pull request to JME
BTW, what is the main target for JME applications? Desktop/WEB?

[Pesegato]

@adi.barda

what is the main target for JME applications? Desktop/WEB?

Do the tutorials and you’ll find out by yourself, I won’t spoil the surprise.
Don’t want to do the tutorials? You’re in the wrong place my friend.
