The Android-PickerView libray provides a flexible solution for implementing time selection functionality in Android apps. With over 10k GitHub stars, this framework offers extensive customizasion options including dialog positioning, item count, button text, and color schemes.

Dependency Setup

implementation 'com.contrarywind:Android-PickerView:4.1.9'

Time Picker Implementation

// Initialize calendar instances
Calendar currentDate = Calendar.getInstance();
Calendar minDate = Calendar.getInstance();
Calendar maxDate = Calendar.getInstance();
minDate.set(2020, Calendar.JANUARY, 1);

TimePickerView timeSelector = new TimePickerBuilder(context, (selectedDate, view) -> {
    long timestamp = selectedDate.getTime();
    String formattedDate = SimpleDateFormat.getDateTimeInstance().format(selectedDate);
    timeDisplay.setText(formattedDate);
})
    .setDisplayType(new boolean[]{true, true, true, false, false, false}) // Show year/month/day
    .setCancelText("Dismiss")
    .setSubmitText("Confirm")
    .setTitleText("Select Date")
    .setTitleColor(ContextCompat.getColor(context, R.color.primary))
    .setRangeDate(minDate, maxDate)
    .setCyclicScroll(true)
    .setDialogStyle(true)
    .build();

Displaying the Picker

timeSelector.show();

Implementation Notes When implementing time range selection, validate that end dates ocurr after start dates by comparing timestamps. Store the initial selection timestamp and verify subsequent selections meet this constraint.
