Installation

Add this line to your gradle/dependencies group:

compile 'com.52inc:scoops:0.1.0'

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");
