（全部源码地址：&&)&
&上篇把界面画出来了， 接下来就是显示里面的功能了，那这篇内容就比较丰富了。
主要有这么几道菜：
1、在地图上弹出泡泡显示信息，并且能相应泡泡的点击时间
2、自动定位当前位置（也就是我的位置） --添加了 GPS定位和基站定位。
3、获取经纬度对应的接到地址名称
那下面就开始代码把，理论知识能讲多少是多少。
一 、 地图弹出泡泡的制作
1 、overlay_popup.xml &直接把layout放出来
&?xml version=&1.0& encoding=&UTF-8&?&
&RelativeLayout xmlns:android=&/apk/res/android&
android:background=&@drawable/bubble_background& android:layout_height=&wrap_content&
android:layout_width=&wrap_content& android:id=&@+id/map_bubblebtn&
android:clickable=&true& android:focusable=&true& android:paddingTop=&5dp&
android:paddingLeft=&5dp& android:paddingRight=&5dp&
android:paddingBottom=&10dp&&
&LinearLayout android:orientation=&vertical& android:id=&@+id/popuptext&
android:layout_width=&wrap_content& android:layout_height=&wrap_content&&
&TextView android:id=&@+id/map_bubbleTitle&
android:ellipsize=&marquee&
android:textSize=&17sp&
android:textColor=&#000000&
android:layout_width=&wrap_content&
android:layout_height=&wrap_content&
android:singleLine=&true&
android:id=&@+id/map_bubbleText&
android:textSize=&14sp&
android:textColor=&#000000&
android:layout_width=&wrap_content&
android:layout_height=&wrap_content&
android:layout_below=&@id/map_bubbleTitle&
&/LinearLayout&
&TextView android:layout_toRightOf=&@id/popuptext& android:layout_width=&wrap_content&
android:layout_height=&wrap_content&
android:background=&@drawable/expander_ic_minimized&
&/RelativeLayout&&
还有泡泡的效果图 ，很多同学做项目都是时间很紧张的，别人贴出来代码都觉得不够直观，有截图是王道，
顺应大部分懒人的习惯，我编截图边发：
看到了吧， 泡泡上有title ,有 desc ,还有一个小icon。我把整个layout 设置成：
android:clickable=&true& android:focusable=&true&
这样这个layout就相当余一个button了，可以点击。
2、那代码怎么实现呢？ FzMapActivity里加入下面代码
private void initPopView(){
if(null == popView){
popView = getLayoutInflater().inflate(R.layout.overlay_popup, null);
mapView.addView(popView, new MapView.LayoutParams(
MapView.LayoutParams.WRAP_CONTENT,
MapView.LayoutParams.WRAP_CONTENT, null,
MapView.LayoutParams.BOTTOM_CENTER));
popView.setVisibility(View.GONE);
在进入主界面是 初始化一下view。
private View popV当然这个变量定义也不能少。
3、自定义&itemizedOverlay & & MyItemizedOverlay
好把，先把代码放出来，光描述怎么写太费劲了。
package com.android.fzmap.
import java.util.ArrayL
import java.util.L
import android.content.C
import android.graphics.C
import android.graphics.drawable.D
import android.util.L
import android.view.KeyE
import android.view.V
import android.view.View.OnClickL
import android.widget.RelativeL
import android.widget.TextV
import com.android.fzmap.FzMapA
import com.android.fzmap.R;
import com.google.android.maps.GeoP
import com.google.android.maps.ItemizedO
import com.google.android.maps.MapC
import com.google.android.maps.MapV
import com.google.android.maps.OverlayI
import com.google.android.maps.ItemizedOverlay.OnFocusChangeL
@SuppressWarnings(&rawtypes&)
public class MyItemizedOverlay extends ItemizedOverlay implements OnFocusChangeListener,OnClickListener{
private static final String TAG = &MyItemizedOverlay&;
private List&OverlayItem& overlays = new ArrayList&OverlayItem&();
private FzMapActivity mC
private GeoPoint point =
private String desc = &&;
private String car_title = &&;
private int layout_x = 0; // 用于设置popview 相对某个位置向x轴偏移
private int layout_y = -30; // 用于设置popview 相对某个位置向x轴偏移
private MapView mMapV
private MapController mMapC
private View mPopV
private Drawable itemD
private Drawable itemSelectD
private OverlayItem selectI
private OverlayItem lastI
public void setItemSelectDrawable(Drawable itemSelectDrawable) {
this.itemSelectDrawable = itemSelectD
public MyItemizedOverlay(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
public MyItemizedOverlay(Drawable defaultMarker, Context context, MapView mapView, View popView, MapController mapCtrl) {
super(boundCenterBottom(defaultMarker));
itemDrawable = defaultM
itemSelectDrawable = defaultM
mContext = (FzMapActivity)
setOnFocusChangeListener(this);
layout_x = itemDrawable.getBounds().centerX();
layout_y = - itemDrawable.getBounds().height();
mMapView =
mPopView = popV
mMapCtrl = mapC
protected OverlayItem createItem(int i) {
return overlays.get(i);
public int size() {
return overlays.size();
public void addOverlay(OverlayItem item) {
overlays.add(item);
populate();
public void removeOverlay(int location) {
overlays.remove(location);
public boolean onTap(GeoPoint p, MapView mapView) {
return super.onTap(p, mapView);
protected boolean onTap(int index) {
return super.onTap(index);
public void draw(Canvas canvas, MapView mapView, boolean shadow) {
super.draw(canvas, mapView, shadow);
public void onFocusChanged(ItemizedOverlay overlay, OverlayItem newFocus) {
Log.d(TAG , &item focus changed!&);
if (null != newFocus) {
Log.d(TAG , &centerY : & + itemDrawable.getBounds().centerY() + &; centerX :& + itemDrawable.getBounds().centerX());
Log.d(TAG , & height : & + itemDrawable.getBounds().height());
MapView.LayoutParams params = (MapView.LayoutParams) mPopView.getLayoutParams();
params.x = this.layout_x;//Y轴偏移
params.y = this.layout_y;//Y轴偏移
point = newFocus.getPoint();
params.point =
mMapCtrl.animateTo(point);
TextView title_TextView = (TextView) mPopView.findViewById(R.id.map_bubbleTitle);
title_TextView.setText(newFocus.getTitle());
TextView desc_TextView = (TextView) mPopView.findViewById(R.id.map_bubbleText);
if(null == newFocus.getSnippet() || &&.equals(newFocus.getSnippet())){
desc_TextView.setVisibility(View.GONE);
this.desc = newFocus.getSnippet();
desc_TextView.setText(this.desc);
desc_TextView.setVisibility(View.VISIBLE);
RelativeLayout button = (RelativeLayout) mPopView.findViewById(R.id.map_bubblebtn);
button.setOnClickListener(this);
mMapView.updateViewLayout(mPopView, params);
mPopView.setVisibility(View.VISIBLE);
selectItem = newF
public void onClick(View v) {
switch (v.getId()) {
主要是继承 &OnFocusChangeListener &监听地图层的变化， 为了方便监听button事件也继承了OnClickListener。
下面这方法监听这个层改变的时间，把泡泡弹出来。&
public void onFocusChanged(ItemizedOverlay overlay, OverlayItem newFocus) {
Log.d(TAG , &item focus changed!&);
if (null != newFocus) {
Log.d(TAG , &centerY : & + itemDrawable.getBounds().centerY() + &; centerX :& + itemDrawable.getBounds().centerX());
Log.d(TAG , & height : & + itemDrawable.getBounds().height());
MapView.LayoutParams params = (MapView.LayoutParams) mPopView.getLayoutParams();
params.x = this.layout_x;//Y轴偏移
params.y = this.layout_y;//Y轴偏移
point = newFocus.getPoint();
params.point =
mMapCtrl.animateTo(point);
TextView title_TextView = (TextView) mPopView.findViewById(R.id.map_bubbleTitle);
title_TextView.setText(newFocus.getTitle());
TextView desc_TextView = (TextView) mPopView.findViewById(R.id.map_bubbleText);
if(null == newFocus.getSnippet() || &&.equals(newFocus.getSnippet())){
desc_TextView.setVisibility(View.GONE);
desc = newFocus.getSnippet();
desc_TextView.setText(desc);
desc_TextView.setVisibility(View.VISIBLE);
RelativeLayout button = (RelativeLayout) mPopView.findViewById(R.id.map_bubblebtn);
button.setOnClickListener(this);
mMapView.updateViewLayout(mPopView, params);
mPopView.setVisibility(View.VISIBLE);
selectItem = newF
二、长按地图获取地图位置并弹出泡泡显示信息
它的继承关系 &LongPressOverlay extends Overlay implements OnDoubleTapListener
LongPressOverlay这个层主要是用来接收长按事件 和双击地图界面的
package com.android.fzmap.
import android.os.H
import android.view.GestureD
import android.view.GestureDetector.OnDoubleTapL
import android.view.GestureDetector.OnGestureL
import android.view.MotionE
import com.android.fzmap.FzMapA
import com.google.android.maps.MapC
import com.google.android.maps.MapV
import com.google.android.maps.O
public class LongPressOverlay extends Overlay implements OnDoubleTapListener,OnGestureListener{
private FzMapActivity mC
private MapView mMapV
private Handler mH
private MapController mMapC
private GestureDetector gestureScanner = new GestureDetector(this);
private int level = 0;
public LongPressOverlay(FzMapActivity context, MapView mapView, Handler handler,MapController mapCtrl){
mContext =
mMapView = mapV
mHandler =
mMapCtrl = mapC
public boolean onTouchEvent(MotionEvent event, MapView mapView) {
return gestureScanner.onTouchEvent(event);
public boolean onSingleTapConfirmed(MotionEvent e) {
public boolean onDoubleTap(MotionEvent e) {
public boolean onDoubleTapEvent(MotionEvent e) {
if(++level % 3 == 0){
mMapCtrl.zoomIn();
level = 0;
public boolean onDown(MotionEvent e) {
public void onShowPress(MotionEvent e) {
public boolean onSingleTapUp(MotionEvent e) {
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
float distanceY) {
public void onLongPress(MotionEvent e) {
mContext.locPoint = mMapView.getProjection().fromPixels((int) e.getX(),
(int) e.getY());
mHandler.sendEmptyMessage(mContext.MSG_VIEW_LONGPRESS);
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
float velocityY) {
&@Override
public void onLongPress(MotionEvent e) {
mContext.locPoint = mMapView.getProjection().fromPixels((int) e.getX(),
(int) e.getY());
mHandler.sendEmptyMessage(mContext.MSG_VIEW_LONGPRESS);
}接收到长按事件后给主界面发消息，由主界面处理。
三、FzLocationManager 这个类用来做gps,基站定位
package com.android.fzmap.
import android.content.C
import android.location.L
import android.location.LocationL
import android.location.LocationM
import android.os.B
import android.util.L
* @author why
public class FzLocationManager {
private final String TAG = &FzLocationManager&;
private static Context mC
private LocationManager gpsLocationM
private LocationManager networkLocationM
private static final int MINTIME = 2000;
private static final int MININSTANCE = 2;
private static FzLocationM
private Location lastLocation =
private static LocationCallBack mC
public static void init(Context c , LocationCallBack callback) {
mContext =
mCallback =
private FzLocationManager() {
// Gps 定位
gpsLocationManager = (LocationManager) mContext
.getSystemService(Context.LOCATION_SERVICE);
Location gpsLocation = gpsLocationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
gpsLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
MINTIME, MININSTANCE, locationListener);
// 基站定位
networkLocationManager = (LocationManager) mContext
.getSystemService(Context.LOCATION_SERVICE);
Location networkLocation = gpsLocationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
networkLocationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER, MINTIME, MININSTANCE,
locationListener);
public static FzLocationManager getInstance() {
if (null == instance) {
instance = new FzLocationManager();
private void updateLocation(Location location) {
lastLocation =
mCallback.onCurrentLocation(location);
private final LocationListener locationListener = new LocationListener() {
public void onStatusChanged(String provider, int status, Bundle extras) {
public void onProviderEnabled(String provider) {
public void onProviderDisabled(String provider) {
public void onLocationChanged(Location location) {
Log.d(TAG, &onLocationChanged&);
updateLocation(location);
public Location getMyLocation() {
return lastL
private static int ENOUGH_LONG = 1000 * 60;
public interface LocationCallBack{
* 当前位置
* @param location
void onCurrentLocation(Location location);
public void destoryLocationManager(){
Log.d(TAG, &destoryLocationManager&);
gpsLocationManager.removeUpdates(locationListener);
networkLocationManager.removeUpdates(locationListener);
public interface LocationCallBack{
* 当前位置
* @param location&
void onCurrentLocation(Location location);
定义一个接口 ，当监听到位置变化时，回调主界面
//locationListener注册监听器到位置服务管理里
networkLocationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER, MINTIME, MININSTANCE,
locationListener);
//位置信息变化回调
private void updateLocation(Location location) {
lastLocation =
mCallback.onCurrentLocation(location);
四、主界面逻辑

部分注释写在代码里了
最后再上一张截图，在室内通过基站定位到我的位置：
五、通过经纬度获取地址
这个单独拷贝出来让大家看看。这个方法获取地址有时候获取不到的，google好像对这个接口有限制。说白了就这这个接口不靠谱。
大家可以尝试用别的方法或手段获取地址
我的代码里加了个死循环去获取位置，这样的方案是不可取的，不过暂时用一下看看效果也好。
*&通过经纬度获取地址
* @param point
private String getLocationAddress(GeoPoint point){
String add = &&;
Geocoder geoCoder = new Geocoder(getBaseContext(),
Locale.getDefault());
List&Address& addresses = geoCoder.getFromLocation(
point.getLatitudeE6() / 1E6, point.getLongitudeE6() / 1E6, 1);
Address address = addresses.get(0);
int maxLine = address.getMaxAddressLineIndex();
if(maxLine &= 2){
add = &address.getAddressLine(1) + address.getAddressLine(2);
add = address.getAddressLine(1);
} catch (IOException e) {
e.printStackTrace();
好了，以上是所有代码， &AndroidManifest.xml 在 &(一)里有。
用google的api获取到的位置放到他的地图上是有偏差的，而且偏差还比不小，大家可以观察一下，这个问题没有很好的免费解决方案。
如果有哪位有什么好建议可以发出来，谢谢。
用基站和gps定位，也没有处理那个是更好的定位的问题。
欢迎大家提建议
