使⽤AndroidStudio开发地图案例之⼀(基本地图功能)1.⾸先看实现效果
打开⾸页如下
3.点击开发⽂档--->Android地图SDK--->获取密钥--->创建应⽤ 如下图所⽰
4.选中所有 编写开发版SHA1和发布版SHA1  获取的⽅法⽹上很多 可以到
5.填写包名需要注意,⾃⼰在AS中创建的应⽤的包名必须与此相同,否则地图只会出现⽹格 没有地图
6.填写完毕后 AK码如下
7.在AS创建应⽤,功能清单⽂件所需权限如下
<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" />
<!-- 访问精确位置的权限 -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!-- 这个权限⽤于进⾏⽹络定位-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <!-- 获取运营商信息,⽤于⽀持提供运营商信息相关的接⼝-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> 8.在application标签⾥加meta-data标签
<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value="s8hW5T2eC0IT1M9Cyzsh3zqPFQ6dQ3eH" />
value的值为你刚刚在百度地图开放平台创建应⽤得到的AK值
9.创建包,此处包⼀定要跟在开放平台创建的包名⼀致,
10.创建案例(页⾯直接创建在Java代码中)代码如下
package ylf.baidumap;
import android.app.Activity;
t.Context;
t.Intent;
aphics.Color;
import android.os.Bundle;
import android.view.ViewGroup;
import android.widget.FrameLayout;

import android.widget.RadioButton;
import android.widget.RadioGroup;
import com.baidu.mapapi.map.BaiduMapOptions;
import com.baidu.mapapi.map.MapStatus;
import com.baidu.mapapi.map.MapView;
import com.del.LatLng;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
/**
/**
* 演⽰MapView的基本⽤法
*/
public class BaseMapDemo extends Activity {
@SuppressWarnings("unused")
private static final String LTAG = SimpleName();
private MapView mMapView;
FrameLayout layout;
private boolean mEnableCustomStyle = true;
private static final int OPEN_ID = 0;
android radiogroupprivate static final int CLOSE_ID = 1;
//⽤于设置个性化地图的样式⽂件
// 精简为1套样式模板:
// "custom_config_dark.json"
private static String PATH = "custom_config_dark.json";
private static int icon_themeId = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
MapStatus.Builder builder = new MapStatus.Builder();
LatLng center = new LatLng(39.915071, 116.403907); // 默认天安门
float zoom = 11.0f; // 默认 11级
/* 该Intent是OfflineDemo中查看离线地图调起的 */
Intent intent = getIntent();
if (null != intent) {
mEnableCustomStyle = BooleanExtra("customStyle", true);
center = new DoubleExtra("y", 39.915071),
zoom = FloatExtra("level", 11.0f);
}
builder.target(center).zoom(zoom);

**
* MapView (TextureMapView)的
* {@link MapView.setCustomMapStylePath( String customMapStylePath)}
* ⽅法⼀定要在MapView(TextureMapView)创建之前调⽤。
* 如果是setContentView⽅法通过布局加载MapView(TextureMapView), 那么⼀定要放置在
* MapView.setCustomMapStylePath⽅法之后执⾏,否则个性化地图不会显⽰
