EasySharedPreference
an easy to use SharedPreference library. You can read/write your object to SharedPreference easily with few lines of code.
Installing
Use Gradle:
compile 'com.kingfisherphuoc:easy_sharedpreference_library:1.3'How to use?
Before you do anything with SharedPreference, you have to initialize the library first. You can do it in your Application class or in your first Activity's OnCreate:
/** * You have to initialize all your preference when open app. * * @param context * @param createDefaultPreference : true if we want to create default {
@link SharedPreferences
}
* @param names
: list of custom {
@link SharedPreferences
}
*/ SharedPreferencesManager.init(this, true, "Pre1","Pre2");
// or using default sharedpreference name only SharedPreferencesManager.init(this, true);
After doing first config, you can use the SharedPreferencesManager at anywhere you want. You can check the sample project for more detail:
// Primitive type SharedPreferencesManager.getInstance().putValue("Test", 1);
// save to default sharedPreference SharedPreferencesManager.getInstance().getValue("Test", Integer.class);
// get from default // you can get default value if the key is not used before. SharedPreferencesManager.getInstance().getValue("TestNotSavedBefore", Integer.class,100);
// return 100 if key does exist // Save your custom object: SharedPreferencesManager.getInstance().putValue("testData", testGun);
Gun gun = SharedPreferencesManager.getInstance().getValue("testData", Gun.class);
// Save list object to another SharedPreference SharedPreferencesManager.getInstance(AnotherPreferenceName).putValue("guns", guns);
List<Gun> datas = SharedPreferencesManager.getInstance(AnotherPreferenceName).getValues("guns", Gun[].class);
// get list object // remove/clear value from sharedPreferences: SharedPreferencesManager.getInstance().clear();
//SharedPreferencesManager.getInstance().remove("test");
// Print the log of all saved value from SharedPreferences: SharedPreferencesManager.getInstance().printAllKeyValues();
//get All keys from SharedPreferences Map<String, ?> allEntries = SharedPreferencesManager.getInstance().getAllKeys();
for (Map.Entry<String, ?> entry : allEntries.entrySet()) {
if (entry == null || entry.getValue() == null) continue;
Log.e("SharedPreferenceManager", entry.getKey() + ": " + entry.getValue().toString());
}
// you can also get the SharedPreference to use if you want to interact directly with it SharedPreferencesManager.getInstance().getSharedPreference();
