首先介绍如何导入百度地图
步骤(其实官方文档写的很清楚了)http://developer.baidu.com/map/index.php?title=androidsdk/guide/introduction
1.注册开发者账号
2.注册你的应用,登陆控制台,然后输入数字签名和包名,得到开发Id
3. 下载android sdk进行配置,我用的是Android studio,配置步骤是,在app底下的libs下导入,没有的话新建,在src/main/目录下新建jniLibs目录,放下那些搜文件,arm64-v8a,armeabi,armeabi-v7a,x86,x86_64,一共5个文件,这个版本目前是这样,参考网址http://developer.baidu.com/map/index.php?title=androidsdk/guide/buildproject
4.在Manifest添加标签
<application>
<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value="开发者 key" />
</application>5.添加所需权限
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_SETTINGS" />6.在布局中加入这个控件
<com.baidu.mapapi.map.MapView
android:id="@+id/bmapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true" />7.在类中初始化代码
public class MainActivity extends Activity {
MapView mMapView = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//在使用SDK各组件之前初始化context信息，传入ApplicationContext
//注意该方法要再setContentView方法之前实现
SDKInitializer.initialize(getApplicationContext());
setContentView(R.layout.activity_main);
//获取地图控件引用
mMapView = (MapView) findViewById(R.id.bmapView);
}
@Override
protected void onDestroy() {
super.onDestroy();
//在activity执行onDestroy时执行mMapView.onDestroy()，实现地图生命周期管理
mMapView.onDestroy();
}
@Override
protected void onResume() {
super.onResume();
//在activity执行onResume时执行mMapView. onResume ()，实现地图生命周期管理
mMapView.onResume();
}
@Override
protected void onPause() {
super.onPause();
//在activity执行onPause时执行mMapView. onPause ()，实现地图生命周期管理
mMapView.onPause();
}
}!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
我写了一个demo,实现了查看卫星地图,实时路况,以及定位和基于android传感器的方向导航
