android利用GPS和高德地图获取定位案例

一、main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <EditText        android:id="@+id/text_location"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:editable="false" /></LinearLayout>

五、小结

1、导入高德地图的jar包（Android_Location_V1.2.0）。

2、用了一个手机卡的旧手机测试，GPS虽然打开，但获取数据为空，改用从网络获取。

3、上述引用，注意在androidmainfest.xml中配置高德地图的相关meta、权限等。

（具体配置参考官网:http://lbs.amap.com/api/android-location-sdk/guide/project/）
