Android常用工具類封裝---SharedPreferencesUtil

標籤：android sharedprefer

SharedPreferences常用於儲存一些簡單的資料，如記錄使用者操作的配置等，使用簡單。

public class SharedPreferencesUtil {//儲存的sharedpreferences檔案名稱private static final String FILE_NAME = "save_file_name";/** * 儲存資料到檔案 * @param context * @param key * @param data */public static void saveData(Context context, String key,Object data){String type = data.getClass().getSimpleName();SharedPreferences sharedPreferences = context.getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);Editor editor = sharedPreferences.edit();if ("Integer".equals(type)){editor.putInt(key, (Integer)data);}else if ("Boolean".equals(type)){editor.putBoolean(key, (Boolean)data);}else if ("String".equals(type)){editor.putString(key, (String)data);}else if ("Float".equals(type)){editor.putFloat(key, (Float)data);}else if ("Long".equals(type)){editor.putLong(key, (Long)data);}editor.commit();}/** * 從檔案中讀取資料 * @param context * @param key * @param defValue * @return */public static Object getData(Context context, String key, Object defValue){String type = defValue.getClass().getSimpleName();SharedPreferences sharedPreferences = context.getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);//defValue為為預設值，如果當前擷取不到資料就返回它if ("Integer".equals(type)){return sharedPreferences.getInt(key, (Integer)defValue);}else if ("Boolean".equals(type)){return sharedPreferences.getBoolean(key, (Boolean)defValue);}else if ("String".equals(type)){return sharedPreferences.getString(key, (String)defValue);}else if ("Float".equals(type)){return sharedPreferences.getFloat(key, (Float)defValue);}else if ("Long".equals(type)){return sharedPreferences.getLong(key, (Long)defValue);}return null;}}
