我使用了以下命令:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.tcyonline.android.myapplication.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<ImageButton
android:id="@+id/ntn"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_gravity="right"
android:layout_marginRight="15dp"
android:layout_marginTop="25dp"
android:background="@android:color/transparent"
android:elevation="10dp"
android:src="@drawable/calendar" />
<include layout="@layout/content_main" />
</FrameLayout>
事实证明,不知怎的,我得到了根&#39; @&#39; XXXXX-aspire&#39; root&#39; @&#39; localhost&#39;和&#39; root&#39; @&#39;%&#39;。
当我删除&#39; root&#39; @&#39; XXXXX-aspire&#39;时,我可以use mysql;
select User, Host from user;
轻松登录。

试试这个SUDO 然后尝试不使用sudo登录
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost';
FLUSH PRIVILEGES;
