获取当前位置 [英] get current location

问题描述

我完成了创建一个向某个位置添加标记的android程序。
但我需要在MAP中显示CURRENT MY LOCATION。我知道这是通过基于位置的服务完成的，但我不知道如何将它合并到我的程序中。

这是我的onCreate命令
<$ p $
public void onCreate（Bundle savedInstanceState）
{
super.onCreate（savedInstanceState）;
setContentView（R.layout.main）;

  // map 
 mapView =（MapView）findViewById （R.id.mapView）; 
 
 // zoom 
 LinearLayout zoomLayout =（LinearLayout）findViewById（R.id.zoom）; 
查看zoomView = mapView.getZoomControls（）; 
 
 zoomLayout.addView（zoomView，
 LinearLayout.LayoutParams（
 LayoutParams.WRAP_CONTENT，
 LayoutParams.WRAP_CONTENT））; 
 mapView.displayZoomControls（true）; 
 
 //菲律宾坐标
 mc = mapView.getController（）; 
字符串坐标[] = {10.952566007，121.78921587}; 
 double lat = Double.parseDouble（coordinates [0]）; 
 double lng = Double.parseDouble（coordinates [1]）; 
 
 p = new GeoPoint（（int）（lat * 1E6），（int）（lng * 1E6））; 
 
 mc.animateTo（p）; 
 mc.setZoom（6）; 
 
 mapOverlay =新的MapOverlay（）; 
 listOfOverlays = mapView.getOverlays（）; 
 listOfOverlays.clear（）; 
 listOfOverlays.add（mapOverlay）; 
 
 mapView.invalidate（）; 
} 
  

我有一个放置标记的onTouchEvent。所以没问题，
问题是我需要在程序开始时显示我的位置。它应该显示一个标记，上面写着你在这里或类似的东西。

p.s：我想我需要将硬编码点改为当前的位置点，但我不知道该怎么做：

解决方案

为了获得手机的当前位置，我使用

< blockquote>

LocationManager locationManager =（LocationManager）this.getSystemService（LOCATION_SERVICE）;

Criteria criteria = new Criteria（）;
criteria.setAccuracy（Criteria.ACCURACY_COARSE）;
String bestProvider = locationManager.getBestProvider（criteria，true）;
location loc = locationManager.getLastKnownLocation（bestProvider）;

在AndroidManifest.xml中为这些$ b定义使用权限

$ b（使用其他地方的优惠地点）

在我的应用程序中，我想将参数传递给地图意图，以便地图显示标记，但是找不到它。按Rick（不是Fred）的建议创建位置叠加层可能是要走的路

I'm done creating an android program that adds a marker to a location. But I need to show CURRENT MY LOCATION in the MAP. I know this is done thru location based services but I don't know how to incorporate it into my program

Here is my onCreate command

  public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    //map
    mapView = (MapView) findViewById(R.id.mapView);

    //zoom
    LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom);  
    View zoomView = mapView.getZoomControls(); 

    zoomLayout.addView(zoomView, 
        new LinearLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, 
            LayoutParams.WRAP_CONTENT)); 
    mapView.displayZoomControls(true);

    //Philippines coordinate
    mc = mapView.getController();
    String coordinates[] = {"10.952566007", "121.78921587"};
    double lat = Double.parseDouble(coordinates[0]);
    double lng = Double.parseDouble(coordinates[1]);

    p = new GeoPoint((int) (lat * 1E6), (int) (lng * 1E6));

    mc.animateTo(p);
    mc.setZoom(6); 

    mapOverlay = new MapOverlay();
    listOfOverlays = mapView.getOverlays();
    listOfOverlays.clear();
    listOfOverlays.add(mapOverlay);  

    mapView.invalidate();
}

I have an onTouchEvent that places the marker. So no problem there, the problem is I need to display my location at the start of the program. It should show a mark that says, "You are here" or something like that in the map.

p.s: I think I need to change the hardcoded point to my current location point, but i don't know how to do that :|

解决方案

In order to get the current location of your phone I use

LocationManager locationManager = (LocationManager)this.getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_COARSE); String bestProvider= locationManager.getBestProvider(criteria, true); Location loc = locationManager.getLastKnownLocation(bestProvider);

define uses-permissions in the AndroidManifest.xml for these (use the fine location for other stuff)

ref. http://code.google.com/p/android-bluetooth-on-motion/source/browse/trunk/BluetoothOnMotion/src/com/elsewhat/android/onmotion/BluetoothOnMotionService.java

In my application I would like to pass a paramter to the maps intent in order for maps to show a marker, but have found no way of doing it. Creating a location overlay as suggested by Rick (who is not Fred) is probably the way to go
