Installation

Add jitpack to your maven sources

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

Add Colorful as a dependency to your build.gradle

dependencies {
    compile 'com.github.garretyoder:Colorful:1.1'
}

Usage

In your Application class, you must initialize Colorful

public class SampleApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        Colorful.init(this);
    }
}

Any Activity you wish to be themed must extend from CActivity

public class MainActivity extends CActivity

Alternatively you can call the following method after super.onCreate(savedInstanceState); and before setContentView();

Colorful.applyTheme(Activity activity);

You can also use Colorful.applyTheme(Activity activity, Boolean overrideBase); where overrideBase defines whether you want Colorful to override your base theme as well, or simply set the primary and accent colors. This allows you to use Colorful with your own pre-defined style, but will break light/dark functionality.

You can set the default theme colors Colorful will use with the defaults() method

public class SampleApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        Colorful.defaults()
                .primaryColor(Colorful.ThemeColor.RED)
                .accentColor(Colorful.ThemeColor.BLUE)
                .translucent(false)
                .dark(true);
        Colorful.init(this);
    }
}

You can set the colors at any time using the config method

Colorful.config(this)
                .primaryColor(Colorful.ThemeColor.RED)
                .accentColor(Colorful.ThemeColor.BLUE)
                .translucent(false)
                .dark(true)
                .apply();

After which you must call apply(); to save your changes

Colorful will handle saving and loading your theme preferences for you.

Color Chooser

Colorful has a inbuilt color chooser dialog that will return a ThemeColor object you can pass directly to Colorful

public class MainActivity extends CActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        setSupportActionBar(((Toolbar) findViewById(R.id.toolbar)));

        ColorPickerDialog dialog = new ColorPickerDialog(this);
        dialog.setOnColorSelectedListener(new ColorPickerDialog.OnColorSelectedListener() {
            @Override
            public void onColorSelected(Colorful.ThemeColor color) {
                //TODO: Do something with the color
            }
        });
        dialog.show();
    }
}

Preference Item

Colorful has a inbuilt preference item that will automatically set Colorful's colors.

Use colorpicker:primary_color and colorpicker:accent_color to tell Colorful which value to set.

        <org.polaric.colorful.ColorPickerPreference
            android:title="@string/primary_color"
            android:summary="@string/primary_color_desc"
            colorpicker:primary_color="true"/>

        <org.polaric.colorful.ColorPickerPreference
            android:title="@string/accent_color"
            android:summary="@string/accent_color_desc"
            colorpicker:accent_color="true"/>
