It supports storing objects other than the standard primitives while decreasing the boiler plate code. It also enables listening for changes on specific keys on a SharedPreference with RxJava support. 8 | 9 | How to Use 10 | ------- 11 | 12 | 13 | #### Gradle Configuration 14 | 15 | Add the following line to the gradle dependencies for your module. 16 | 17 | ```groovy 18 | compile 'com.tramsun.libs:prefcompat:0.9.4' 19 | ``` 20 | 21 | #### Usage 22 | 23 | First initialize the PrefCompat library in your Application class. 24 | 25 | ```java 26 | public class Application extends android.app.Application { 27 | @Override 28 | public void onCreate() { 29 | super.onCreate(); 30 | Pref.init(this); 31 | } 32 | } 33 | ``` 34 | 35 | Then, use the Pref class to store and access data in SharedPreferences. 36 | 37 | ```java 38 | public class MainActivity extends Activity { 39 | 40 | @Override public void onCreate(Bundle inState) { 41 | // Default SharedPreferences 42 | Pref.putString("name", "Tushar"); 43 | Pref.putDouble("weight", 79.24); 44 | Pref.putObject("dependents", new Dependent("Radhika", 62.24)); 45 | 46 | Double weight = Pref.getDouble("weight"); 47 | Dependent mom = Pref.getObject("dependents", Dependent.class); 48 | 49 | // Named SharedPreferences can also be used 50 | Pref.from("Scores").putIntList("level_1", [60, 20, 80, 25, 30]); 51 | 52 | List scores = Pref.from("Scores").getIntList("level_1"); 53 | } 54 | } 55 | ``` 56 | 57 | Listen on changes to specific key in a SharedPreference 58 | 59 | ```java 60 | // Listen on a key in default SharedPreferences 61 | Pref.listenOn("age").subscribe(new Action1() { 62 | @Override 63 | public void call(String key) { 64 | Log.d(TAG, "1. Value of " + key + " changed to " + Pref.getInt(key)); 65 | } 66 | }); 67 | 68 | // Listen on a key in named SharedPreferences 69 | Pref.from("scores").listenOn("user1").subscribe(new Action1() { 70 | @Override 71 | public void call(String key) { 72 | Log.d(TAG, "2. Scores of " + key + " changed to " + Pref.from(SP_SCORES).getDoubleList(key).toString()); 73 | } 74 | }); 75 | ``` 76 | 77 | Do note that these subscriptions are standard RxJava subscriptions, hence they need to be unsubscribed, failing which will lead to leaking of subscriptions 78 | 79 | 80 | License 81 | ------- 82 | 83 | Copyright 2015 - 2016 Tushar Acharya 84 | 85 | Licensed under the Apache License, Version 2.0 (the "License");
