GPS定位+经纬度定位

1、从高德地图下载sdk并放入相应的包

2、权限+key：

<meta-dataandroid:name="com.amap.api.v2.apikey"android:value="key" />

key放自己的！！！

<uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.CHANGE_CONFIGURATION" /><uses-permission android:name="android.permission.WRITE_SETTINGS" />

3、简单的xml布局

<LinearLayout xmlns:android="/apk/res/android"xmlns:tools="/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"tools:context="com.example.dyw.testgps.TestLocation"><LinearLayoutandroid:orientation="horizontal"android:layout_width="match_parent"android:layout_height="wrap_content"android:gravity="center_horizontal"><TextViewandroid:text="经度"android:layout_width="wrap_content"android:layout_height="wrap_content" /><EditTextandroid:id="@+id/lng"android:layout_width="85dp"android:layout_height="wrap_content"android:text="118.899714"android:inputType="numberDecimal"/><TextViewandroid:text="纬度"android:layout_width="wrap_content"android:layout_height="wrap_content" /><EditTextandroid:id="@+id/lat"android:layout_width="85dp"android:layout_height="wrap_content"android:text="31.90397"android:inputType="numberDecimal"/><Buttonandroid:id="@+id/loc"android:text="定位"android:layout_width="0dp"android:layout_height="wrap_content"android:layout_weight="4"/></LinearLayout><LinearLayoutandroid:orientation="horizontal"android:layout_width="match_parent"android:layout_height="wrap_content"android:gravity="center_horizontal"><RadioGroupandroid:id="@+id/rg"android:orientation="horizontal"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_weight="1"><RadioButtonandroid:id="@+id/manual"android:text="手动定位"android:checked="true"android:layout_width="wrap_content"android:layout_height="wrap_content" /><RadioButtonandroid:id="@+id/gps"android:text="GPS定位"android:layout_width="wrap_content"android:layout_height="wrap_content" /></RadioGroup></LinearLayout><com.amap.api.maps.MapViewandroid:id="@+id/map1"android:layout_width="match_parent"android:layout_height="match_parent"></com.amap.api.maps.MapView></LinearLayout>

4、Java：
