Favor

A easy way of using Android SharedPreferences.

How to use this library

• Using Gradle

 compile 'com.cocosw:favor:0.2.0@aar'

• Using Maven

<dependency>
  <groupId>com.cocosw</groupId>
  <artifactId>favor</artifactId>
  <version>0.2.0</version>
  <type>apklib</type> </dependency>

API

1 Define a interface.

@AllFavor public interface Account {

  @Default("No Name")
  String getUserName();

  String setPassword(String password);
 
}

2 The FavorAdapter class generates an implementation of the interface.

account = new FavorAdapter.Builder(getContext()).build().create(Account.class);
 account.setPassword("Passw0rd");
 String username = account.getUserName();

API Declaration

@AllFavor

@AllFavor public interface Account {

  @Default("No Name")
  String getUserName();

  String getPassword();
 
}

@Favor

 @Favor("city")
  @Default("Sydney")
  String city();

equals

 PreferenceManager.getDefaultSharedPreferences(context).getString("city","Sydney");

And you can simplify it, Favor will extract the key from the method name

 @Favor
  @Default("Sydney")
  String city();

@Default

 @Default("18")
  int age();

 @Default("true")
  boolean alive();

@Commit

By default, Favor will call editor.apply() (>api9), but you can force it to use editor.commit() by @Commit

 @Favor
  @Commit
  void setAddress(String address);

RxPreference

You are a RxJava fan, easy! (rx-preferences dependency is required)

 @Favor
  @Default("No Name")
  Preference<String> name();

Advanced usage

Favor support put/get all primitive types, including int/long/float/String/bool, String set is also supported for API>=11. From 0.2.0, Favor (Experimentally) supports Serializable object saving/loading.

 public class Image implements Serializable {

  ....
  
}

@Favor
  Image image();

@Favor
  void setImage(Image image);

There is one limitation that you can't set default value for Serializable preference item.
