试试这个最好的方法:

PreferenceConnector.java

import android.content.Context;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;

public class PreferenceConnector {
    public static final String PREF_NAME = "ENUMERATOR_PREFERENCES";
    public static final String PREF_NAME_REMEMBER = "ENUMERATOR_REMEMBER";
    public static final int MODE = Context.MODE_PRIVATE;


    public static final String name = "name";


    public static void writeBoolean(Context context, String key, boolean value) {
        getEditor(context).putBoolean(key, value).commit();
    }

    public static boolean readBoolean(Context context, String key,
            boolean defValue) {
        return getPreferences(context).getBoolean(key, defValue);
    }

    public static void writeInteger(Context context, String key, int value) {
        getEditor(context).putInt(key, value).commit();

    }

    public static int readInteger(Context context, String key, int defValue) {
        return getPreferences(context).getInt(key, defValue);
    }

    public static void writeString(Context context, String key, String value) {
        getEditor(context).putString(key, value).commit();

    }

    public static String readString(Context context, String key, String defValue) {
        return getPreferences(context).getString(key, defValue);
    }

    public static void writeLong(Context context, String key, long value) {
        getEditor(context).putLong(key, value).commit();
    }

    public static long readLong(Context context, String key, long defValue) {
        return getPreferences(context).getLong(key, defValue);
    }

    public static SharedPreferences getPreferences(Context context) {
        return context.getSharedPreferences(PREF_NAME, MODE);
    }

    public static Editor getEditor(Context context) {
        return getPreferences(context).edit();
    }

}

写入值:

PreferenceConnector.writeString(this, PreferenceConnector.name,"Girish");

并获得价值使用:

String name= PreferenceConnector.readString(this, PreferenceConnector.name, "");

如果你想存储你从响应中得到的整个对象，它可以通过这样做来实现，

首先，在util类中创建一个将JSON转换为字符串的方法，如下所示。

 public static <T> T fromJson(String jsonString, Class<T> theClass) {
    return new Gson().fromJson(jsonString, theClass);
}

然后在共享偏好类中执行如下操作，

 public void storeLoginResponse(yourResponseClass objName) {

    String loginJSON = UtilClass.toJson(customer);
    if (!TextUtils.isEmpty(customerJSON)) {
        editor.putString(AppConst.PREF_CUSTOMER, customerJSON);
        editor.commit();
    }
}

然后为getPreferences创建一个方法

public Customer getCustomerDetails() {
    String customerDetail = pref.getString(AppConst.PREF_CUSTOMER, null);
    if (!TextUtils.isEmpty(customerDetail)) {
        return GSONConverter.fromJson(customerDetail, Customer.class);
    } else {
        return new Customer();
    }
}

然后只是调用第一个方法时，你得到的响应和 其次，当你需要从分享偏好中获取数据时

String token = SharedPrefHelper.get().getCustomerDetails().getAccessToken();

这是所有。

希望对你有所帮助。

快乐的编码();

我知道这个帖子有点旧了。 但我还是要把这个贴出来，希望它能帮助到一些人。 通过将对象序列化为String，可以将任何Object的字段存储为共享首选项。 这里我使用GSON存储共享首选项的任何对象。

保存对象到首选项:

public static void saveObjectToSharedPreference(Context context, String preferenceFileName, String serializedObjectKey, Object object) {
    SharedPreferences sharedPreferences = context.getSharedPreferences(preferenceFileName, 0);
    SharedPreferences.Editor sharedPreferencesEditor = sharedPreferences.edit();
    final Gson gson = new Gson();
    String serializedObject = gson.toJson(object);
    sharedPreferencesEditor.putString(serializedObjectKey, serializedObject);
    sharedPreferencesEditor.apply();
}

从首选项检索对象:

public static <GenericClass> GenericClass getSavedObjectFromPreference(Context context, String preferenceFileName, String preferenceKey, Class<GenericClass> classType) {
    SharedPreferences sharedPreferences = context.getSharedPreferences(preferenceFileName, 0);
    if (sharedPreferences.contains(preferenceKey)) {
        final Gson gson = new Gson();
        return gson.fromJson(sharedPreferences.getString(preferenceKey, ""), classType);
    }
    return null;
}

注意:

记得在gradle的dependencies中添加compile 'com.google.code.gson:gson:2.6.2'。

例子:

//assume SampleClass exists
SampleClass mObject = new SampleObject();

//to store an object
saveObjectToSharedPreference(context, "mPreference", "mObjectKey", mObject);

//to retrive object stored in preference
mObject = getSavedObjectFromPreference(context, "mPreference", "mObjectKey", SampleClass.class);

更新:

正如@Sharp_Edge在评论中指出的那样，上述解决方案不适用于List。

稍微修改一下getSavedObjectFromPreference()的签名——从Class<GenericClass> classType到Type classType将使这个解决方案一般化。修改后的函数签名

public static <GenericClass> GenericClass getSavedObjectFromPreference(Context context, String preferenceFileName, String preferenceKey, Type classType)

用于调用,

getSavedObjectFromPreference(context, "mPreference", "mObjectKey", (Type) SampleClass.class)

编码快乐!

在SharedPreferences中存储Model的数组列表

Add this dependency implementation 'com.google.code.gson:gson:2.8.8' Then after you convert your Model Class into JSON using Gson. Gson gson = new Gson(); String json = gson.toJson(chModelArrayList); //here chModelArrayList is a ArrayList<Model> of Model Class Then after you can add this string to SharedPreferences SharedPreferences preferences; //Create Object of SharedPreferences SharedPreferences.Editor editor; //Create Object of SharedPreferences.Editor //initialize SharedPreferences preferences = activity.getPreferences(Context.MODE_PRIVATE); editor = preferences.edit(); //Add-In SharedPreferences editor.putString(key, json); editor.commit(); for your list from SharedPreferences String json = preferences.getString(key, defVal); Gson gson = new Gson(); //Pass Your Model ArrayList in TypeToken Type type = new TypeToken<ArrayList<ChModel>>() {}.getType(); //here you get your list ArrayList<ChModel> switchGroup1 = gson.fromJson(json, type);

如果你的对象很复杂，我建议序列化/XML/JSON，并将这些内容保存到SD卡。你可以在这里找到关于如何保存到外部存储的其他信息: http://developer.android.com/guide/topics/data/data-storage.html#filesExternal

要添加到@MuhammadAamirALi的答案，您可以使用Gson保存和检索对象列表

保存用户定义对象的列表到SharedPreferences

public static final String KEY_CONNECTIONS = "KEY_CONNECTIONS";
SharedPreferences.Editor editor = getPreferences(MODE_PRIVATE).edit();

User entity = new User();
// ... set entity fields

List<Connection> connections = entity.getConnections();
// convert java object to JSON format,
// and returned as JSON formatted string
String connectionsJSONString = new Gson().toJson(connections);
editor.putString(KEY_CONNECTIONS, connectionsJSONString);
editor.commit();

从SharedPreferences获取用户定义对象的列表

String connectionsJSONString = getPreferences(MODE_PRIVATE).getString(KEY_CONNECTIONS, null);
Type type = new TypeToken < List < Connection >> () {}.getType();
List < Connection > connections = new Gson().fromJson(connectionsJSONString, type);
