Simple Android SharedPreferences wrapper.

Last update: Nov 11, 2022

Overview

Prefs

Simple Android SharedPreferences wrapper.

Repository

Add this in your root build.gradle file (not your module build.gradle file):

allprojects {
	repositories {
		...
		maven { url "https://jitpack.io" }
	}
}

Dependency

Add this to your module's build.gradle file (make sure the version matches the JitPack badge above):

dependencies {
	...
	compile 'com.github.GrenderG:Prefs:1.3'
}

Usage

This is the basic usage, you can read values (specifying a default value or not) and write values like so:

  Prefs.with(yourContext).readInt(YOUR_KEY_VALUE);
  Prefs.with(yourContext).readInt(YOUR_KEY_VALUE, defaultValue);
  
  Prefs.with(yourContext).writeInt(YOUR_KEY_VALUE, valueToStore);

You can also specify a custom name for the preferences' name:

  Prefs.with(yourContext, "CUSTOM_NAME").readInt(YOUR_KEY_VALUE);

And force the re-instantiation of the Prefs instance:

  Prefs.with(yourContext, true).readInt(YOUR_KEY_VALUE);
  Prefs.with(yourContext, "CUSTOM_NAME", true).readInt(YOUR_KEY_VALUE);

You can also set and retrieve ordered String sets and unordered String sets.

Customize preferences file name

I notice by default this library handles preferences with the name 'preferences' but I think it would be cool to specify the name of the Shared Preference file the user wants to access.

Basically creating a call like: Prefs.with(yourContext, "FILE NAME").readInt(YOUR_KEY_VALUE); having the second parameter optional, defaulting to the what the library does now.

I used below code for shared prefs. My friend suggested not use static methods. He advised me to use the class like you have implemented. Can you please suggest with which way we can improve performance.

    public static void saveStringPref(Context context, String key, String value) {

        SharedPreferences sharedPref = context.getSharedPreferences(
                "Pref-Values", Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPref.edit();
        editor.putString(key, value);
        editor.commit();
    }

    public static String getStringPref(Context context, String key,
                                       String defaultValue) {
        SharedPreferences sharedPref = context.getSharedPreferences(
                "Pref-Values", Context.MODE_PRIVATE);
        return sharedPref.getString(key, defaultValue);
    }

    public static void saveIntPref(Context context, String key, int value) {

        SharedPreferences sharedPref = context.getSharedPreferences(
                "Pref-Values", Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPref.edit();
        editor.putInt(key, value);
        editor.commit();
    }

    public static int getIntPerf(Context context, String key,
                                 int defaultValue) {
        SharedPreferences sharedPref = context.getSharedPreferences(
                "Pref-Values", Context.MODE_PRIVATE);
        return sharedPref.getInt(key, defaultValue);
    }

    public static void saveBooleanPref(Context context, String key, boolean value) {

        SharedPreferences sharedPref = context.getSharedPreferences(
                "Pref-Values", Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPref.edit();
        editor.putBoolean(key, value);
        editor.commit();
    }

    public static boolean getBooleanPerf(Context context, String key,
                                         boolean defaultValue) {
        SharedPreferences sharedPref = context.getSharedPreferences(
                "Pref-Values", Context.MODE_PRIVATE);
        return sharedPref.getBoolean(key, defaultValue);
    }

    public static void deletePref(Context context, String key) {
        SharedPreferences sharedPref = context.getSharedPreferences(
                "Pref-Values", Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPref.edit();
        editor.remove(key);
        editor.commit();
    }
