Scoops

Android library for managing and applying multiple defined R.style.Theme.... themes at runtime for dyanically changing the look and feel of your application

Demo

Installation

Add this line to your gradle/dependencies group:

compile 'com.52inc:scoops:1.0.0'

Then you will need to initialize the singleton in your Application subclass like this:

Scoop.waffleCone()
        .addFlavor("Default", R.style.Theme_Scoop, true)
        .addFlavor("Light", R.style.Theme_Scoop_Light)
        .addDayNightFlavor("DayNight", R.style.Theme_Scoop_DayNight)
        .addFlavor("Alternate 1", R.style.Theme_Scoop_Alt1)
        .addFlavor("Alternate 2", R.style.Theme_Scoop_Alt2, R.style.Theme_Scoop_Al2_Dialog)
        .setSharedPreferences(PreferenceManager.getDefaultSharedPreferences(this))
        .initialize();

Use

Basic usage is to call the .apply(...) method in your activities before you call setContentView(R.layout.some_layout) like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Apply Scoop to the activity
    Scoop.getInstance().apply(this);

    // Set the activity content
    setContentView(R.layout.activity_main);

    ...
}

You can also use .applyDialog(...) to apply the specified dialog theme resource to an activity (to make an activity appear as a dialog with the correct theme)

Advanced Use

There are a few custom attributes you can use to make sure your application has the correct styling when switching themes. These are:

<attr name="toolbarTheme" format="reference" />
<attr name="toolbarPopupTheme" format="reference" />
<attr name="toolbarItemTint" format="reference|color" />

Then in your layouts, apply the toolbar themes like so:

<android.support.v7.widget.Toolbar
        ...
        
        android:theme="?attr/toolbarTheme"
        app:popupTheme="?attr/toolbarPopupTheme"
        
        />

Then define the attribute in your themes like this:

<style name="Theme.Scoop" parent="Theme.AppCompat.NoActionBar">
	...
    <item name="toolbarTheme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
    <item name="toolbarPopupTheme">@style/ThemeOverlay.AppCompat.Light</item>
    <item name="toolbarItemTint">#fff</item>
</style>

You can also apply the toolbarItemTint color to all the icons in the toolbar by calling .apply(Context, Menu)

Settings Menu

This library provides a built in theme chooser settings screen to use called ScoopSettingsActivity that you can use by utilizing one of it's static Intent factories:

ScoopSettingsActivity.createIntent(Context);
ScoopSettingsActivity.createIntent(Context, R.string.some_title_to_use);
ScoopSettingsActivity.createIntent(Context, "Some title to use");

Dynamic color property changing

This is the ability to have a view or attribute update it's color (background, src, text, etc) whenever the user/developer chnages the color for a defined property, or Topping. Please refer to Sample App for actual code references.

Installation

buildscript {
    repositories {
       jcenter()
    }
    dependencies {
	 	...
    	classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}

compile 'com.52inc:scoops:1.0.0'
apt 'com.52inc:scoops-compiler:1.0.0'

Manual Implementation

This does not require the compiler dependency to use.

Toolbar mAppBar;

@Override
public void onCreate(Bundle savedInstanceState){
	super.onCreate(savedInstanceState);
	setContentView(R.layout.some_layout);
	
	Scoop.getInstance().bind(this, Toppings.PRIMARY, mAppBar)
					 .bindStatusBar(this, Toppings.PRIMARY_DARK);
}

@Override
public void onDestroy(){
	super.onDestroy();
	Scoop.getInstance().unbind(this);
}	

void onSomeEvent(){
	Scoop.getInstance().update(Toppings.PRIMARY, someColorInt) 
 					 .update(Toppings.PRIMARY_DARK, someDarkColorInt);
}

Annotated Implementation

There are two annotations to use to binding views and the like to color properties that can be dynamically updated (i.e. palette, etc) which are @BindTopping() and @BindToppingStatus().

@BindTopping()

This annotation is for binding View's to certain color properties, aka Topping, so that when you later update that color property say after running Palette on an image, or for whatever reason, the view you binded will be automatically updated. The topping Id is the value required for the annotation but you can optionally define a ColorAdapter (Used to determine how the color change is applied to your View) you want to use and an Interpolator to customize the color change animation.

@BindToppingStatus()

This annotation is used to bind an Activities status bar color to a color property so you can dynamically change the color the window's status bar. Like @BindTopping() you can also define an Interpolator to use in the animation, however a ColorAdapter is not an option here since there is only one way to apply color to a status bar.

Example

@BindToppingStatus(Toppings.PRIMARY_DARK)
public class MainActivity extends AppCompatActivity {

    @BindTopping(Toppings.PRIMARY)
    @BindView(R.id.appbar)
    Toolbar mAppBar;

    @BindTopping(
            value = Toppings.ACCENT,
            adapter = FABColorAdapter.class,
            interpolator = AccelerateInterpolator.class
    )
    @BindView(R.id.fab)
    FloatingActionButton mFab;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Bind ButterKnife
        ButterKnife.bind(this);

        // Bind Scoops
        Scoop.getInstance().bind(this);
		
		...
    }

    @Override
    protected void onDestroy() {
        Scoop.getInstance().unbind(this);
        super.onDestroy();
    }
}
