An easy way to pick date and time on Android using RxJava2

To use this library your minSdkVersion must be >= 16.

In your build.gradle :

dependencies {
    implementation 'com.salah.rxdatetimepicker:rxdatetimepicker:1.0.1'
}

Kotlin :

RxDateTimePicker
        .with(this)
        .show()
        .subscribe { date -> Log.d("Date",date.toString()) }

Java :

RxDateTimePicker
        .with(this)
        .show()
        .subscribe(new Consumer<Date>() {
            @Override
            public void accept(@NonNull Date date) throws Exception {
                Log.d("Date",date.toString());
            }
        });

By default both date and time picker dialog will show. You can specify date only or time only picker as shown below

RxDateTimePicker
        .with(this)
        .pickTimeOnly() // or .pickDateOnly()
        .show()
        .subscribe { date -> Log.d("Date",date.toString()) }

Be default Java Date object are being emitted. You can convert this to String in required format.

Kotlin :

RxDateTimePicker
        .with(this)
        .pickDateOnly()
        .show()
        .flatMap { date -> RxDateConverters.toString(date,"dd-MM-yyyy") }
        .subscribe { date -> Log.d("Date",date) }

Java :

RxDateTimePicker
        .with(this)
        .pickTimeOnly()
        .is24HourView(false)
        .show()
        .flatMap(new Function<Date, MaybeSource<String>>() {
            @Override
            public MaybeSource<String> apply(@NonNull Date date) throws Exception {
                return RxDateConverters.toString(date,"mm-hh");
            }
        })
        .subscribe(new Consumer<String>() {
            @Override
            public void accept(@NonNull String date) throws Exception {
                Log.d("Date",date);
            }
        });

Converting to Calender object

RxDateTimePicker
        .with(this)
        .show()
        .flatMap { date -> RxDateConverters.toCalender(date) }
        .subscribe { calender -> Log.d("Date",calender.getDisplayName(Calendar.MONTH, LONG,Locale.US)) }
