Android 如何从SharedReference中获取此作为响应对象？

我已经创建了如下代码所示的本地数据

public class LocalDataSource {

private SharedPreferences mSharedPreferences;
private static LocalDataSource sLocalRepository;

private LocalDataSource() {
    mSharedPreferences = PreferenceManager.getDefaultSharedPreferences(App.getApp());
}

public static LocalDataSource getInstance() {
    if (sLocalRepository == null) {
        sLocalRepository = new LocalDataSource();
    }
    return sLocalRepository;
}

public void saveResponse(Context ctx, String object, String key) {
    mSharedPreferences.edit().putString(key, object).apply();
}

public String getResposne(String key) {
    return mSharedPreferences.getString(key, "");
}

}

@Override
        public void onSuccess(LoadLookUpResponse body) {
            super.onSuccess(body);

            if (body.responseCode != CommonResponse.Code.SUCCESS) {

                PopupErrorDialog.newInstance(body.responseMessage.header, body.responseMessage.message, body.responseMessage.btnText1, null, null, null).show(getSupportFragmentManager(), "popup_error");

            } else {
                mData = body.data;

                LocalDataSource.getInstance().saveResponse(getApplicationContext(), mData.toString(), "data");


            }
        }

然后我将对象另存为SharedReferences中的字符串，如下代码所示

public class LocalDataSource {

private SharedPreferences mSharedPreferences;
private static LocalDataSource sLocalRepository;

private LocalDataSource() {
    mSharedPreferences = PreferenceManager.getDefaultSharedPreferences(App.getApp());
}

public static LocalDataSource getInstance() {
    if (sLocalRepository == null) {
        sLocalRepository = new LocalDataSource();
    }
    return sLocalRepository;
}

public void saveResponse(Context ctx, String object, String key) {
    mSharedPreferences.edit().putString(key, object).apply();
}

public String getResposne(String key) {
    return mSharedPreferences.getString(key, "");
}

}

@Override
        public void onSuccess(LoadLookUpResponse body) {
            super.onSuccess(body);

            if (body.responseCode != CommonResponse.Code.SUCCESS) {

                PopupErrorDialog.newInstance(body.responseMessage.header, body.responseMessage.message, body.responseMessage.btnText1, null, null, null).show(getSupportFragmentManager(), "popup_error");

            } else {
                mData = body.data;

                LocalDataSource.getInstance().saveResponse(getApplicationContext(), mData.toString(), "data");


            }
        }

现在我可以得到这个对象字符串，当我调用这个

LocalDataSource.getInstance().getResposne("data");

现在，如何将其作为响应对象（LoadLookUpResponse.Data）在特定类中访问？因为，它正在返回字符串。但我的回答是字符串和数组

提前谢谢

您可以将其以JSON字符串的形式保存在SharedReferences中。然后，在获取时，您可以在类中获取它。

您可以将类中的值转换为字符串

我没有得到。请用exampleOk详细说明，您可以将JSON响应转换为GSON，为此，您可以使用完整的类。你可以参考这个链接

public class PreferenceUtil {
    public static void saveToPreferences(Context context, String preferenceName, String preferenceValue) {
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context.getApplicationContext());
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putString(preferenceName, preferenceValue);
        editor.apply();
    }

    public static void saveToPreferences(Context context, String preferenceName, boolean preferenceValue) {
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context.getApplicationContext());
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putBoolean(preferenceName, preferenceValue);
        editor.apply();
    }

    public static String readFromPreferences(Context context, String preferenceName, String defaultValue) {
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context.getApplicationContext());
        return sharedPreferences.getString(preferenceName, defaultValue);
    }

    public static boolean readFromPreferences(Context context, String preferenceName, boolean defaultValue) {
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context.getApplicationContext());
        return sharedPreferences.getBoolean(preferenceName, defaultValue);
    }
}

// Use this class to write preference and read preference
// Create instance of PreferenceUtil class in your Activity
private PreferenceUtil mPreferenceUtil;
mPreferenceUtil.saveToPreferences(contex, prefKey, prefValue);
