这是我用来在首选项中创建和存储值的代码。传出是字符串变量。

SharedPreferences sp = getSharedPreferences(outgoing, Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();                
editor.putString("PhoneNo","Hi");
editor.commit();

这是从 SharedPreference 获取值的代码。

SharedPreferences sp 
=getSharedPreferences(outgoing,Activity.MODE_PRIVATE);
String calln = sp.getString("PhoneNo","0");
Toast.makeText(mContext, "SHARED"+calln,Toast.LENGTH_LONG).show();
