您可以创建自定义的SharedPreference类

public class YourPreference {   
    private static YourPreference yourPreference;
    private SharedPreferences sharedPreferences;

    public static YourPreference getInstance(Context context) {
        if (yourPreference == null) {
            yourPreference = new YourPreference(context);
        }
        return yourPreference;
    }

    private YourPreference(Context context) {
        sharedPreferences = context.getSharedPreferences("YourCustomNamedPreference",Context.MODE_PRIVATE);
    }

    public void saveData(String key,String value) {
        SharedPreferences.Editor prefsEditor = sharedPreferences.edit();
        prefsEditor .putString(key, value);
        prefsEditor.commit();           
    }

    public String getData(String key) {
        if (sharedPreferences!= null) {
           return sharedPreferences.getString(key, "");
        }
        return "";         
    }
}

你可以像这样获得你的偏好实例:

YourPreference yourPrefrence = YourPreference.getInstance(context);
yourPreference.saveData(YOUR_KEY,YOUR_VALUE);

String value = yourPreference.getData(YOUR_KEY);

SharedPreferences mPref;
SharedPreferences.Editor editor;

public SharedPrefrences(Context mContext) {
    mPref = mContext.getSharedPreferences(Constant.SharedPreferences, Context.MODE_PRIVATE);
    editor=mPref.edit();
}

public void setLocation(String latitude, String longitude) {
    SharedPreferences.Editor editor = mPref.edit();
    editor.putString("latitude", latitude);
    editor.putString("longitude", longitude);
    editor.apply();
}

public String getLatitude() {
    return mPref.getString("latitude", "");
}

public String getLongitude() {
    return mPref.getString("longitude", "");
}

public void setGCM(String gcm_id, String device_id) {
     editor.putString("gcm_id", gcm_id);
    editor.putString("device_id", device_id);
    editor.apply();
}

public String getGCMId() {
    return mPref.getString("gcm_id", "");
}

public String getDeviceId() {
    return mPref.getString("device_id", "");
}


public void setUserData(User user){

    Gson gson = new Gson();
    String json = gson.toJson(user);
    editor.putString("user", json);
    editor.apply();
}
public User getUserData(){
    Gson gson = new Gson();
    String json = mPref.getString("user", "");
    User user = gson.fromJson(json, User.class);
    return user;
}

public void setSocialMediaStatus(SocialMedialStatus status){

    Gson gson = new Gson();
    String json = gson.toJson(status);
    editor.putString("status", json);
    editor.apply();
}
public SocialMedialStatus getSocialMediaStatus(){
    Gson gson = new Gson();
    String json = mPref.getString("status", "");
    SocialMedialStatus status = gson.fromJson(json, SocialMedialStatus.class);
    return status;
}

Initialise here..
 SharedPreferences msharedpref = getSharedPreferences("msh",
                    MODE_PRIVATE);
            Editor editor = msharedpref.edit();

store data...
editor.putString("id",uida); //uida is your string to be stored
editor.commit();
finish();


fetch...
SharedPreferences prefs = this.getSharedPreferences("msh", Context.MODE_PRIVATE);
        uida = prefs.getString("id", "");

在“偏好”中设置值:

// MY_PREFS_NAME - a static String variable like: 
//public static final String MY_PREFS_NAME = "MyPrefsFile";
SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit();
 editor.putString("name", "Elena");
 editor.putInt("idName", 12);
 editor.apply();

从首选项检索数据:

SharedPreferences prefs = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE); 
String name = prefs.getString("name", "No name defined");//"No name defined" is the default value.
int idName = prefs.getInt("idName", 0); //0 is the default value.
