Android 百度地图 - 初步集成

说明：

集成百度地图，如果你看着开发文档集成，那么机会走很多弯路，百度地图的开发文档写的太简单，考虑的情况太少了。

因为百度第一的版本太多了，并且现在实行了定位、热力、全景的分包形式，所以如果你按照了开发文档说的下载了全量BaiduLBS_AndroidSDK同时又看了开发文档下载了定位sdk locSDK_6.13 那么你的项目必定冲突无法编译成功。

我的做法是：下载百度地图demo，完全按照demo进行开发。

百度地图Demo:

Demo地址：http://lbsyun.baidu.com/index.php?title=androidsdk/sdkandev-download

如果是AndroidStudio开发：建议参考demo中的 BaiduMap_AndroidSDK_v4.3.1_Sample-BaiduMapsApiASDemo 包名有可能根据实际情况二改变。

注意：

libs的jar包一定和.so包对应。例如：locSDK_6.13.jar 一定 要对应 liblocSDK6a.so 否则 无法实现定位成功。
秘钥填写：发布版SHA1 和 开发版SHA1都要对应填写，否则直接用AndroidStudio运行的项目无法定位。
以上都会造成定位错误，定位会定位在非洲的海洋中。

参考Demo开发后的个人扩展代码记录：

1、配置秘钥AndroidManifest.xml

<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
<!-- 这个权限用于进行网络定位 -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<!-- 这个权限用于访问GPS定位 -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<!-- OpenGLES 2.0 -->
<uses-feature android:glEsVersion="0x00020000" android:required="true" />

<supports-screens
android:anyDensity="true"
android:largeScreens="true"
android:normalScreens="false"
android:resizeable="true"
android:smallScreens="true" />

<!--baidu-->
<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value="你的key 或者 AK" />

<service
android:name="com.baidu.location.f"
android:enabled="true"
android:process=":remote" >
</service>

2、导入.jar包和.so包



3、考入LocationDemo.java代码

package baidumapsdk.demo.map;

group.setOnCheckedChangeListener(radioButtonListener);

// 地图初始化

if (Math.abs(x - lastX) > 1.0) {
mCurrentDirection = (int) x;
locData = new MyLocationData.Builder()

super.onDestroy();
}

}


4、考入布局代码

1、参考BaiduMap_AndroidSDK_v4.3.1_Sample-BaiduMapsApiASDemo 的LocationDemo.java类实现了简单的定位。

2、不显示缩放控件activity_location.xml；主要的是MapView

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

<com.baidu.mapapi.map.MapView
android:id="@+id/bmapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true" />

<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginTop="80dip"
android:background="#D000"
android:minWidth="100dip"
android:orientation="vertical"
android:padding="2dp" >

<RadioGroup
android:id="@+id/radioGroup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="定位icon" >

<RadioButton
android:id="@+id/defaulticon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="默认图标" >
</RadioButton>

<RadioButton
android:id="@+id/customicon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="自定义图标" >
</RadioButton>
</RadioGroup>
</LinearLayout>

<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginRight="25dp"
android:layout_marginTop="10dip" />

</RelativeLayout>

5、调试运行。
6、控件控制

mMapView.showZoomControls(false);//是否显示缩放控件
