这是我的主要活动类：
public class MyActivity extends MapActivity implements LocationListener, OnClickListener{
private MapView mapView;
private MyItemizedOverlay itemizedOverlay;
Button route;
Drawable drawableDot;
static GeoPoint src;
static GeoPoint des;
Canvas canvas;
Paint paint;
boolean shadow;
private LocationManager locManager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
route = (Button) findViewById(R.id.cmd_submit);
route.setOnClickListener(this);
//fetch the map view from the layout
mapView = (MapView) findViewById(R.id.myMapView);
//make available zoom controls
mapView.setBuiltInZoomControls(true);
//latitude and longitude of Rome
double lat = 41.889882;
double lon = 12.479267;
//create geo point
GeoPoint point = new GeoPoint((int)(lat * 1E6), (int)(lon *1E6));
//get the MapController object
MapController controller = mapView.getController();
//animate to the desired point
controller.animateTo(point);
//set the map zoom to 13
// zoom 1 is top world view
controller.setZoom(13);
//invalidate the map in order to show changes
mapView.invalidate();
// Use the location manager through GPS
locManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
0, this);
//get the current location (last known location) from the location manager
Location location = locManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
//if location found display as a toast the current latitude and longitude
if (location != null) {
Toast.makeText(
this,
"Current location:nLatitude: " + location.getLatitude()
+ "n" + "Longitude: " + location.getLongitude(),
Toast.LENGTH_LONG).show();
point = new GeoPoint((int)(location.getLatitude()*1E6),(int)(location.getLongitude() *1E6));
controller.animateTo(point);
} else {
Toast.makeText(this, "Cannot fetch current location!",
Toast.LENGTH_LONG).show();
}
//when the current location is found – stop listening for updates (preserves battery)
locManager.removeUpdates(this);
// fetch the drawable - the pin that will be displayed on the map
Drawable drawable = this.getResources().getDrawable(R.drawable.marker);
// create and add an OverlayItem to the MyItemizedOverlay list
OverlayItem overlayItem = new OverlayItem(point, "", "");
itemizedOverlay = new MyItemizedOverlay(drawable,this);
itemizedOverlay.setGestureDetector(new GestureDetector(new MyGestureDetector()));
itemizedOverlay.addOverlay(overlayItem);
// add the overlays to the map
mapView.getOverlays().add(itemizedOverlay);
mapView.invalidate();
//when the current location is found – stop listening for updates (preserves battery)
locManager.removeUpdates(this);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
class MyGestureDetector extends SimpleOnGestureListener implements OnClickListener{
ArrayList<GeoPoint> points =new ArrayList<GeoPoint>();
@Override
public boolean onSingleTapConfirmed(MotionEvent event) {
// fetch the correspondent point from the map
Log.d("A condition", "d5al l methodaaya");
GeoPoint p = mapView.getProjection().fromPixels((int) event.getX(),(int) event.getY());
points.add(p);
// create an overlay item and clear all others
OverlayItem o = new OverlayItem(p, null, null);
// itemizedOverlay.clear();
itemizedOverlay.addOverlay(o);
// add the overlay item
//mapView.getOverlays().clear();
mapView.getOverlays().add(itemizedOverlay);
mapView.invalidate();
Geocoder geoCoder = new Geocoder(getBaseContext(),
Locale.getDefault());
// get the address based on the coordinates
try {
List<Address> addresses = geoCoder.getFromLocation(p.getLatitudeE6() / 1E6, p.getLongitudeE6() / 1E6, 1);
String addressString = "";
if (addresses.size() > 0) {
for (int i = 0; i < addresses.get(0)
.getMaxAddressLineIndex(); i++)
addressString += addresses.get(0).getAddressLine(i)
+ " - ";
}
Toast.makeText(getBaseContext(), addressString,
Toast.LENGTH_SHORT).show();
//Add action item
ActionItem addAction = new ActionItem();
addAction.setTitle("Add");
addAction.setIcon(getResources().getDrawable(R.drawable.marker));
//Accept action item
ActionItem accAction = new ActionItem();
accAction.setTitle("Accept");
accAction.setIcon(getResources().getDrawable(R.drawable.marker));
//Upload action item
ActionItem upAction = new ActionItem();
upAction.setTitle("Upload");
upAction.setIcon(getResources().getDrawable(R.drawable.marker ));
final QuickAction mQuickAction = new QuickAction(getBaseContext());
mQuickAction.addActionItem(addAction);
mQuickAction.addActionItem(accAction);
mQuickAction.addActionItem(upAction);
现在的问题是，如果我尝试下面的带有路由的OnClickListener（这是一个按钮），它可以很好地工作，但如果我尝试整个地图，它绝对不会起任何作用。（如果有另一种完全不同的方式为引脚实现setOnClickListener，那就太棒了！）
// mapView.setOnClickListener(new View.OnClickListener() {
// @Override
// public void onClick(View v) {
// mQuickAction.show(v);
// }
// });
route.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mQuickAction.show(v);
}
});
//setup the action item click listener
mQuickAction.setOnActionItemClickListener(new QuickAction.OnActionItemClickListener() {
public void onItemClick(int pos) {
if (pos == 0) { //Add item selected
Toast.makeText(MyActivity.this, "Add item selected", Toast.LENGTH_SHORT).show();
} else if (pos == 1) { //Accept item selected
Toast.makeText(MyActivity.this, "Accept item selected", Toast.LENGTH_SHORT).show();
} else if (pos == 2) { //Upload item selected
Toast.makeText(MyActivity.this, "Upload items selected", Toast.LENGTH_SHORT).show();
}
}
@Override
public void onItemClick(QuickAction source, int pos,
int actionId) {
if (pos == 0) { //Add item selected
Toast.makeText(MyActivity.this, "Add item selected", Toast.LENGTH_SHORT).show();
} else if (pos == 1) { //Accept item selected
Toast.makeText(MyActivity.this, "Accept item selected", Toast.LENGTH_SHORT).show();
} else if (pos == 2) { //Upload item selected
Toast.makeText(MyActivity.this, "Upload items selected", Toast.LENGTH_SHORT).show();
}
}
});
} catch (IOException e) {
e.printStackTrace();
}
return true;
}
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
float velocityY) {
return super.onFling(e1, e2, velocityX, velocityY);
}
@Override
public boolean onDown(MotionEvent e) {
return false;
}
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
}
}
}
此外，我尝试了这里的建议，但没有奏效。Android为谷歌地图上的标记设置侦听器如有任何帮助，我们将不胜感激，提前感谢！
如果你想在用户点击标记时打开弹出菜单，那么首先删除以下代码：
itemizedOverlay.setGestureDetector(new GestureDetector(new MyGestureDetector()));
我想你不知道ItemizedOverlay中的onTap（）方法，所以使用它而不是使用手势检测器，因为我认为你不能为不是视图的Android类使用手势检测器（我提供了下面的代码），你必须在你的MyItemizedOverlay类中使用以下代码：
@Override
public boolean onTap(int index)
{
//Put the code for the creation of a pop-up menu, I'd suggest using a custom Dialog
//box and putting options in it. However, you seem to be using ActionItems, I'm
//not sure what they are.
}
