用SharedPreferences写的存储工具类

读写更方便

    public class PersistenceUtil {  
        private Context context;  
      
        public Context getContext() {  
            return context;  
        }  
      
        public void setContext(Context context) {  
            this.context = context;  
        }  
      
        public PersistenceUtil(Context context) {  
            this.context = context;  
        }  
      
        public void savePersistence(String name, String key, Integer value) {  
            SharedPreferences sharedPreferences = context.getSharedPreferences(  
                    name, Context.MODE_PRIVATE);  
            Editor editor = sharedPreferences.edit();  
            editor.putInt(key, value);  
            editor.commit();  
        }  
      
        public void savePersistence(String name, String key, String value) {  
            SharedPreferences sharedPreferences = context.getSharedPreferences(  
                    name, Context.MODE_PRIVATE);  
            Editor editor = sharedPreferences.edit();  
            editor.putString(key, value);  
            editor.commit();  
        }  
      
        public void savePersistence(String name, String key, Boolean value) {  
            SharedPreferences sharedPreferences = context.getSharedPreferences(  
                    name, Context.MODE_PRIVATE);  
            Editor editor = sharedPreferences.edit();  
            editor.putBoolean(key, value);  
            editor.commit();  
        }

        }

            Boolean value = sharedPreferences.getBoolean(key, false);  
            return value;  
        }  
      
        public Integer getPersistenceInteger(String name, String key) {  
            SharedPreferences sharedPreferences = context.getSharedPreferences(
