一：百度地图开发必须要到百度开发平台android开发api下载相应的库，已经申请百度地图开发key，在这个博客里面有详细的说明和演示，（如果不懂得请看此文章） http://104zz.iteye.com/blog/1680781
二：新建项目baidumaplocation.设计main.xml文件这里注意的是MapView控件必须使用来自百度库封装好的com.baidu.mapapi.MapView 。设计代码如下：
Xml代码
<?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" >
<FrameLayout
android:id="@+id/map_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<!-- 百度MapView控件 -->
<com.baidu.mapapi.MapView
android:id="@+id/map_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:apiKey="0Mg_koWoyZUiYLfZxmPfp4LKInB5LqTnagYueaw"
android:clickable="true"
android:enabled="true" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="vertical"
android:paddingBottom="105dip" >
<!-- 地址信息显示TextView -->
<TextView
android:id="@+id/map_bubbleText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/location_tips"
android:gravity="left|center"
android:maxEms="12"
android:paddingLeft="12dip"
android:paddingRight="10dip"
android:text="@string/load_tips"
android:textColor="#cfcfcf"
android:textSize="14sp" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="vertical" >
<!-- 位置指标显示ImageView -->
<ImageView
android:id="@+id/point_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginBottom="30dip"
android:src="@drawable/point_start" />
</LinearLayout>
</FrameLayout>
</LinearLayout>
三：创建覆盖整个地图捕捉触控事件的MyMapOverlay继承Overlay
Java代码
import android.view.MotionEvent;
import com.baidu.mapapi.GeoPoint;
import com.baidu.mapapi.MapView;
import com.baidu.mapapi.Overlay;
//覆盖整个地图捕捉触控事件的OverLay
public abstract class MyMapOverlay extends Overlay{
private int point_X;
private int point_Y;
private GeoPoint newPoint;
public MyMapOverlay(int x,int y){
point_X = x;
point_Y = y;
}
boolean flagMove=false;
//这里实现根据地图移动时重新获取屏幕中心点的经纬度坐标
@Override
public boolean onTouchEvent(MotionEvent event, MapView mapView) {
System.out.println("X->"+event.getX()+":"+point_X);
System.out.println("Y->"+event.getY()+":"+point_Y);
if(event.getAction() == MotionEvent.ACTION_DOWN){
changePoint(newPoint,1);
}else if(event.getAction() == MotionEvent.ACTION_UP){
newPoint = mapView.getProjection().fromPixels(point_X,point_Y);
changePoint(newPoint,2);
}
return false;
}
public abstract void changePoint(GeoPoint newPoint,int type);
}
四：LocationActivity类继承百度库的MapActivity以及实现LocationListener接口，代码如下：
package com.location.activity;
Java代码
import java.io.IOException;

mapView.setClickable(true);
mMapCtrl = mapView.getController();
point_X = this.getWindowManager().getDefaultDisplay().getWidth() / 2;
point_Y = this.getWindowManager().getDefaultDisplay().getHeight() / 2;
mOverlay = new MyMapOverlay(point_X, point_Y) {
@Override
public void changePoint(GeoPoint newPoint, int type) {
if (type == 1) {
mHandler.sendEmptyMessage(MSG_GONE_ADDRESSNAME);
} else {
locPoint = newPoint;
mHandler.sendEmptyMessage(MSG_VIEW_LONGPRESS);
}
}
};
mapOverlays = mapView.getOverlays();
if (mapOverlays.size() > 0) {
mapOverlays.clear();
}
mapOverlays.add(mOverlay);
mMapCtrl.setZoom(20);
}
private void initMap() {

}
private Handler mHandler = new Handler() {
@Override

switch (msg.what) {

{
if (null == locPoint)
return;

五：在AndroidManifest.xml住添加相关的访问权限
<!-- 访问网络的权限 -->
Xml代码
<uses-permission android:name="android.permission.INTERNET" />
<!-- 访问精确位置的权限 -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!-- 访问网络状态的权限 -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!-- 访问WIFI网络状态的权限 -->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<!-- 改变WIFI网络状态的权限 -->
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<!-- 读写存储卡的权限 -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!-- 读取电话状态的权限 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
六：运行结果如下图：

}五：在AndroidManifest.xml住添加相关的访问权限
<!-- 访问网络的权限 -->
Xml代码
<uses-permission android:name="android.permission.INTERNET" />
<!-- 访问精确位置的权限 -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!-- 访问网络状态的权限 -->
