Import

1. To use this lib you need add jitpack.io repository to your root build.gradle:

    allprojects {
        repositories {
            jcenter()
            maven { url 'https://jitpack.io' } // add this line
        }
    }
   

   Note: don't add the jitpack.io repository under buildscript closure.

2. Add SunriseSunsetView dependency in your module build.gradle:

    // ...
    // if Android Gradle Plugin after v3.0
    implementation 'com.github.tianma8023:SunriseSunsetView:0.0.2' 
    // if Android Gradle Plugin before v3.0
    // compile 'com.github.tianma8023:SunriseSunsetView:0.0.2'
   

Usage

1. SunriseSunsetView can be placed in layout xml file:

    <com.github.tianma8023.ssv.SunriseSunsetView
        android:id="@+id/ssv"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:layout_width="match_parent"
        app:ssv_label_text_color="@color/colorAccent"
        app:ssv_label_text_size="16sp"
        app:ssv_label_horizontal_gap="12dp"
        app:ssv_label_vertical_gap="2dp"
        app:ssv_shadow_color="@color/lightGreen"
        app:ssv_sun_color="@color/amber"
        app:ssv_sun_radius="10dp"
        app:ssv_track_color="@color/teal"
        app:ssv_track_width="1.5dp"
    />
   

2. You need to set sunrise and sunset time before starting animation:

    mSunriseSunsetView = (SunriseSunsetView) findViewById(R.id.ssv);
    // ...
    mSunriseSunsetView.setSunriseTime(new Time(sunriseHour, sunriseMinute));
    mSunriseSunsetView.setSunsetTime(new Time(sunsetHour, sunsetMinute));
    // start animation
    mSunriseSunsetView.startAnimate();
   

Custom attributes are supported:

attribute	format	default	description
ssv_track_color	color\	reference	#FFFFFF	track color
ssv_track_width	dimension	4px	track width
ssv_sun_radius	dimension	20px	sun radius

Other api:

// fotmat label by set label formatter
mSunriseSunsetView.setLabelFormatter(new SunriseSunsetLabelFormatter() {
    @Override
    public String formatSunriseLabel(@NonNull Time sunrise) {
        return formatLabel(sunrise);
    }

    @Override
    public String formatSunsetLabel(@NonNull Time sunset) {
        return formatLabel(sunset);
    }

    private String formatLabel(Time time) {
        return String.format(Locale.getDefault(), "%02dh %02dm", time.hour, time.minute);
    }
});
