Horizontal Picker

What is this?

HorizontalPicker is a custom-build Android View used for choosing dates (similar to the native date picker) but draws horizontally into a vertically narrow container. It allows easy day picking using the horizontal pan gesture.

Too see it in action, download the demo app to try it out.

This is what it looks like.

Features

• Date selection using a smooth swipe gesture
• Date selection by clicking on a day slot
• Date selection from code using the HorizontalPicker java object
• Month and year view
• Today button to jump to the current day
• Localized day and month names
• Configurable number of generated days (default: 120)
• Configurable number of offset generated days before the current date (default: 7)
• Customizable set of colors, or themed through the app theming engine

Note: This library uses the JodaTime library to work with days.

Requirements

• Android 4.1 or later (Minimum SDK level 16)
• Android Studio (to compile and use)
• Eclipse is not supported

Getting Started

In your app module's Gradle config file, add the following dependency:

dependencies {
    compile 'com.github.jhonnyx2012:horizontal-picker:1.0.6'
}

Then to include it into your layout, add the following:

<com.github.jhonnyx2012.horizontalpicker.HorizontalPicker
    android:id="@+id/datePicker"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

In your activity, you need to initialize it and set a listener, like this:

public class MainActivity extends AppCompatActivity implements DatePickerListener {
    @Override
    protected void onCreate(@Nullable final Bundle savedInstanceState) {
        // setup activity
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // find the picker
        HorizontalPicker picker = (HorizontalPicker) findViewById(R.id.datePicker);

        // initialize it and attach a listener
        picker
            .setListener(this)
            .init();
    }

    @Override
    public void onDateSelected(@NonNull final DateTime dateSelected) {
        // log it for demo
        Log.i("HorizontalPicker", "Selected date is " + dateSelected.toString());
    }
}

Finally, you can also configure the number of days to show, the date offset, or set a date directly to the picker. For all options, see the full configuration below.

    // at init time
    picker
        .setListener(listner)
        .setDays(20)
        .setOffset(10)
        .setDateSelectedColor(Color.DKGRAY)
        .setDateSelectedTextColor(Color.WHITE)
        .setMonthAndYearTextColor(Color.DKGRAY)
        .setTodayButtonTextColor(getColor(R.color.colorPrimary))
        .setTodayDateTextColor(getColor(R.color.colorPrimary))
        .setTodayDateBackgroundColor(Color.GRAY)
        .setUnselectedDayTextColor(Color.DKGRAY)
        .setDayOfWeekTextColor(Color.DKGRAY)
        .setUnselectedDayTextColor(getColor(R.color.textColor))
        .showTodayButton(false)
        .init();

    // or on the View directly after init was completed
    picker.setBackgroundColor(Color.LTGRAY);
    picker.setDate(new DateTime().plusDays(4));
