安卓中百度地图的使用
1.导入到程序中
2.一些权限配置
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="demo.jq.com.lbstest">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value="Uvo2IDT7i6KFtdeoH1gr7TUrGy6WkvPg"
/>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name="com.baidu.location.f" android:enabled="true" android:process=":remote">
</service>
</application>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
</manifest>
3.定义显示空间
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/position_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"
/>
<com.baidu.mapapi.map.MapView
android:id="@+id/bmapView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
/>
</LinearLayout>
4.实现功能
