在loginactivity中用sharedpreference保存的用户信息，怎样在其他activity和fragment中读取

Question

loginactivity中的代码

SharedPreferences.Editor editor = getSharedPreferences("token",MODE_PRIVATE).edit();

editor.putString("name",responseData.data.user.getUsername() );


editor.putString("jwt",responseData.data.getJwt());
    editor.commit();

能够成功保存

其他地方读取

SharedPreferences preferences;

preferences = ContextApplication.getAppContext().getSharedPreferences("toke",Context.MODE_PRIVATE);

String token = preferences.getString("jwt","null");
String appId = preferences.getString("name","null");
Log.d("MentalitydataAcitvity:","username========"+appId);
Log.d("MentalitydataAcitvity:","jwt======"+token);

不报错 但是打印的数据为空 怎样解决

Answer 1

SharedPreferences.Editor editor = getSharedPreferences("token",MODE_PRIVATE).edit();
preferences = ContextApplication.getAppContext().getSharedPreferences("toke",Context.MODE_PRIVATE);
为什么上面是token，下面变成了toke，
String token = preferences.getString("jwt","null");<-----是null不是"null"
