SimplePreferences
A simple library to work with SharedPreferences.
How add it
On your build.gradle
add the maven repository from jitpack.io
repositories {
maven {
url "https://jitpack.io"
}
}
On your project level ( app/build.gradle
) add the androidSimplePreferences dependency.
dependencies {
compile 'com.github.brunodles:AndroidSimplePreferences:{
latest version
}
'
}
Now, you just need to run a GradleSync.
Choosing how to work with it
The first thing you need to do is create a new class.
There is two options, use it as a ActiveRecord
where the object can save \ load \ clean itself. The problem is that you need to extend our class to make it work.
The other option, you can use a DAO to save many objects, this way you don't need to extend any class from the lib.
Using it as ActiveRecord
To use as an active record you just need to
- Create your data class
- Make it extends
ActivePreferences
- Annotate your persistant fields with
@Property
This class is intent to be used when you have only one of this kind, like the current user data, the user preferences or even the app preferences.
Apply \ Reload \ Clean
To save the data as an activePreferences you just need to call apply()
.
To load the data you just need to call load()
.
To clean the data you just need to call clean()
.
That simple.
Fast sample
public class CurrentUser extends ActivePreferences {
@Property public String name;
@Property public boolean isJedi = false;
}
CurrentUser user = new CurrentUser()
user.name = "Anakin Skywalker";
// to save the current object on a preferences
user.apply();
// Reload the object
user.reload();
// Clean the preferences data.
user.clean();
Using it as Data Access Object
To use the DAO is simple too, you need to:
- Create your data class
- Annotate the persistant fields with
@Property
Saving \ Loading \ Cleaning
To save the data with a Dao you just need to call dao.save(object, key)
.
To load the data you just need to call dao.load(emptyObject, key)
.
To clean the data you just need to call dao.clean(key)
.
Fast sample
public class Person{
@Property public String name;
@Property public boolean isJedi = false;
}
Person person = new Person()
person.name = "Anakin Skywalker";
// to save the current object on a preferences
// "this" is a context
DaoPreferences dao = new DaoPreferences(this)
// save the person with the key "anakin"
dao.save(person, "anakin");
// load the person
person = dao.load(person, "anakin");
// clean the data
dao.clean("anakin");
Sample
You can see it in "pratice", it have some explanations too. On the sample you will see how to
- Create a data class
- Save data
- load data
