JarCastingdtpreference
Library Info
This library contains a date preference, time preference and date and time preference library for Android, allowing users to choose a specific date for DatePreference, a specific time for TimePreference, and a specific date and time for DateTimePreference.
The time value for DatePreference would be at midnight of the selected date, while the date value for the TimePreference would be the current date.
All the values for the preference are stored in the form of a long variable representing the number of milliseconds since the epoch, which can be easily converted to a Calendar object through Calendar.setTimeInMills(long millis).
Installation
This library is available in Maven Central and a backup is available on my personal repository. To install, you would need to include the following into your project/build.gradle:
implementation 'com.pcchin.dtpreference:dtpreference:1.1.3'
You may also need to include the following in your build.gradle:
buildscript {
...
}
allprojects {
...
repositories {
...
// Use this if Maven Central is not working
// maven { url "https://nexus.pcchin.com/repository/maven-releases/" }
mavenCentral()
}
}
Usage
For the layout XML, simply include the preference without any additional changes. e.g.:
<com.pcchin.dtpreference.DatePreference
android:title="Date Preference"
android:key="pref_date"
/>
For your preference fragment, you would to need to override the onDisplayPreferenceDialog function as shown below in order to display their respective dialogs:
public class PreferenceFragment extends PreferenceFragmentCompat {
@Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
// ... add your preferences here
}
@Override
public void onDisplayPreferenceDialog(Preference preference) {
// Use instanceof to check if the preference is one of
// DatePreference, TimePreference or DateTimePreference
DialogFragment dialogFragment = null;
if (preference instanceof TimePreference) {
// If it is, then set the dialog fragment to their respective Dialog classes as shown below
dialogFragment = TimePreferenceDialog.newInstance(preference.getKey());
} else if (preference instanceof DatePreference) {
dialogFragment = DatePreferenceDialog.newInstance(preference.getKey());
// Alternatively, you can specify the minimum date and maximum date as well
dialogFragment = DatePreferenceDialog.newInstance(preference.getKey(), minDate, maxDate);
} else if (preference instanceof DateTimePreference) {
dialogFragment = DateTimePreferenceDialog.newInstance(preference.getKey());
// You can also specify the minimum and maximum date here
dialogFragment = DateTimePreferenceDialog.newInstance(preference.getKey(), minDate, maxDate);
}
if (dialogFragment != null) {
// If it is one of our preferences, show it
dialogFragment.setTargetFragment(this, 0);
dialogFragment.show(getFragmentManager(), "YOUR TAG HERE");
} else {
// Let super handle it
super.onDisplayPreferenceDialog(preference);
}
}
}
The following functions are available for each Dialog:
setInitialTime(long time): Sets the initial time displayed by the TimePicker.
setInitialDate(long date): Sets the initial date displayed by the DatePicker.
setInitialDateTime(long dateTime): Sets the initial date and time displayed by both the TimePicker and the DatePicker.
