在我的 Android 应用程序中,我想在 map 上标记一个位置(我知道该位置的地址)。当我在 map 上标记它时,我也想显示位置名称。我该怎么做?
我有这个:OverlayItem(p ,"Kaufland", "Magic Kingdom"),但在 map 上只出现点,没有名称。
这是我的代码:
package com.ShoppingList.Shops;
import java.io.IOException;
import java.util.List;
import java.util.Locale;
import com.ShoppingList.R;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
import java.util.ArrayList;
import android.graphics.Canvas;
import android.graphics.drawable.Drawable;
import android.location.Address;
import android.location.Geocoder;
import android.os.Bundle;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;
public class ShowMap extends MapActivity {
private MapView mapView;
MapController mc;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.showmap);
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
mapView.setClickable(true);
Drawable marker=getResources().getDrawable(R.drawable.pushpin);
marker.setBounds(0, 0, marker.getIntrinsicWidth(),
marker.getIntrinsicHeight());
InterestingLocations funPlaces = new InterestingLocations(marker);
mapView.getOverlays().add(funPlaces);
GeoPoint pt = funPlaces.getCenter(); // get the first-ranked point
mapView.getController().setCenter(pt);
mapView.getController().setZoom(15);
}
@Override
protected boolean isLocationDisplayed() {
return false;
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
class InterestingLocations extends ItemizedOverlay {
private List locations = new ArrayList();
private Drawable marker;
String adresa;
public InterestingLocations(Drawable marker)
{
super(marker);
this.marker=marker;
// create locations of interest
Bundle bundle = getIntent().getExtras();
adresa = bundle.getString("adress");
Geocoder geoCoder = new Geocoder(ShowMap.this, Locale.getDefault());
try {
List addresses = geoCoder.getFromLocationName(adresa, 5);
String add = "";
if (addresses.size() > 0) {
GeoPoint p = new GeoPoint((int) (addresses.get(0).getLatitude() * 1E6),
(int) (addresses.get(0).getLongitude() * 1E6));
locations.add(new OverlayItem(p ,"Kaufland", "Magic Kingdom"));
}
} catch (IOException e) {
e.printStackTrace();
}
populate();
}
@Override
public void draw(Canvas canvas, MapView mapView, boolean shadow) {
super.draw(canvas, mapView, shadow);
boundCenterBottom(marker);
}
@Override
protected OverlayItem createItem(int i) {
return locations.get(i);
}
@Override
public int size() {
return locations.size();
}
}
}
最佳答案
我不敢相信没有更简单的方法,但它看起来并不像有。这是一种方法: http://binwaheed.blogspot.com/2011/05/android-display-title-on-marker-in.html
此外,我强烈建议您使用抗锯齿,除非您想要难看的文本:
TextPaint paintText = new TextPaint(Paint.ANTI_ALIAS_FLAG);
