前言
听说腾讯的mmkv很牛皮,可以替代SharedPreferences,主要用来保存设置,比如串口号、波特率、摄像头预览角度等等,来试一下哈O(∩_∩)O哈哈~
1.依赖引入,app build.gradle
implementation 'com.tencent:mmkv-static:1.0.23'
2.封装类
import android.content.Context; import com.tencent.mmkv.MMKV; public class SharedPreferencesManager { private static MMKV kv; public static void init(Context context) { String rootDir = MMKV.initialize(context); System.out.println("mmkv root: " + rootDir); kv = MMKV.defaultMMKV(); } public static void putBoolean(String key, boolean value) { kv.encode(key, value); } public static Boolean getBoolean(String key) { return kv.decodeBool(key, false); } public static Boolean getBoolean(String key, boolean defValue) { return kv.decodeBool(key, defValue); } public static void putInteger(String key, int value) { kv.encode(key, value); } public static int getInteger(String key) { return kv.decodeInt(key, 1); } public static int getInteger(String key, int defValue) { return kv.decodeInt(key, defValue); } public static void putString(String key, String value) { kv.encode(key, value); } public static String getString(String key) { return kv.decodeString(key, ""); } public static String getString(String key, String defaultValue) { return kv.decodeString(key, defaultValue); } }
3.在自定义的application中初始化
public class XXApplication extends Application { @Override public void onCreate() { super.onCreate(); /*初始化SharedPreferences*/ SharedPreferencesManager.init(this); } }
4.尽情使用吧
String mcuPath = SharedPreferencesManager.getString(Constants.SP_KEY_COM_MCU, Constants.DEFAULT_COM_MCU); SharedPreferencesManager.putString(Constants.SP_KEY_COM_MCU, mcuPath);
