百度地图sdk怎么用

配置文件 

meta里加上key

        <meta-data
            android:name="com.baidu.lbsapi.API_KEY"
            android:value="Tdu6i8odfOHqiQ7Cm8zAV6qdmRQLE76X" />
        <service
            android:name="com.baidu.location.f"
            android:enabled="true"
            android:process=":remote"></service>

在application里

 SDKInitializer.initialize(this)

布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextView
        android:id="@+id/tv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <com.baidu.mapapi.map.MapView
        android:id="@+id/mv"
        android:layout_width="match_parent"
        android:layout_height="match_parent"></com.baidu.mapapi.map.MapView>
</LinearLayout>
