如何保存TextView的价值观共享preferences [英] How to save TextView Values in SharedPreferences

问题描述

如何保存TextView的价值观共享preferences，见下面我的code，让我知道如何存储到共享preferences和检索的onCreate（..）

How to save TextView values in SharedPreferences, see my code below and let me know how to store to SharedPreferences and retrieve in onCreate(..)

我的code是这样的：

my code looks like this:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        txtOperative = (TextView) findViewById(R.id.currentOperative);
        txtEvent = (TextView) findViewById(R.id.currentEvent);

        intent = getIntent();
        strEventName = intent.getStringExtra("eventName");
        strOperativeName = intent.getStringExtra("operativeName");

        txtEvent.setText(strEventName);
        txtOperative.setText(strOperativeName);         
    }

我想在TextViews，每当用户回来到这个活动始终显示这些值

推荐答案

可以方便地使用这种对于保存在共享preference你的TextView值

Simple use this for save your TextView value in sharedpreference

 SharedPreferences sp = getSharedPreferences("key", 0);
 SharedPreferences.Editor sedt = sp.edit();
 sedt.putString("textvalue", txtEvent.getText().toString());
 sedt.putString("txtopertaive", txtOperative.getText().toString());
 sedt.commit();

现在以后找回随时随地在你的Activity类或任何其它活动由

Now after that retrieve it anywhere in your Activity class or any other Activity by

 SharedPreferences sp = getSharedPreferences("key", 0);
 String tValue = sp.getString("textvalue","");
 String tOperative = sp.getString("txtopertaive","");
