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", "");

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);

如何初始化?

// 0 - for private mode`
SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0); 

Editor editor = pref.edit();

如何在共享偏好中存储数据?

editor.putString("key_name", "string value"); // Storing string

OR

editor.putInt("key_name", "int value"); //Storing integer

别忘了申请:

editor.apply();

如何从共享首选项检索数据?

pref.getString("key_name", null); // getting String

pref.getInt("key_name", 0); // getting Integer

希望这对你有帮助:)

您还可以看看我过去为这个目的编写的示例项目。我在本地保存一个名称，并在用户请求或应用程序启动时检索它。

但是，此时最好使用commit(而不是apply)来持久化数据。更多信息请点击这里。

共享偏好是如此容易学习，所以看看这个 关于共享偏好的简单教程

import android.os.Bundle;
import android.preference.PreferenceActivity;

    public class UserSettingActivity extends PreferenceActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

      addPreferencesFromResource(R.xml.settings);

    }
}

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.
