点圈

Question

这是我的代码，允许用户在地图上绘制圆圈以标记某个区域，然后保存它但我想获得圆形线的点，就像在我的图片中一样，因为我想保存这些点但我不知道采用圆点的方法是什么。

public class Map extends  Activity implements OnMapClickListener{

final int RQS_GooglePlayServices = 1;
private GoogleMap myMap;

Circle myCircle;

@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_map);

 TabHost th = (TabHost) findViewById (R.id.tabhost);
 th.setup();

 TabSpec ts = th.newTabSpec("tag1");
 ts.setContent(R.id.tab2);
 ts.setIndicator("Draw Boundary");
 th.addTab(ts);

 ts = th.newTabSpec("tag2");
 ts.setContent(R.id.tab1);
 ts.setIndicator("Map");
 th.addTab(ts);

 ts = th.newTabSpec("tag3");
 ts.setContent(R.id.tab3);
 ts.setIndicator("Sign out");
 th.addTab(ts);

 FragmentManager myFragmentManager = getFragmentManager();
 MapFragment myMapFragment = (MapFragment)myFragmentManager.findFragmentById(R.id.map);
 myMap = myMapFragment.getMap();
 myMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
 myMap.setOnMapClickListener(this);
 myMap.setMyLocationEnabled(true);
 myMap.getCameraPosition();
}

@Override
public void onMapClick(LatLng point) {
 CircleOptions circleOptions = new CircleOptions()
 .center(point)   //set center
 .radius(500)   //set radius in meters
 .fillColor(Color.TRANSPARENT)  //default
 .strokeColor(Color.BLUE)
 .strokeWidth(5);

 myCircle = myMap.addCircle(circleOptions);

}
}

Answer 1

我认为单程是

private ArrayList<CircleOptions> points = new ArrayList<CircleOptions>

@Override
public void onMapClick(LatLng point) {
 CircleOptions circleOptions = new CircleOptions()
 .center(point)   //set center
 .radius(500)   //set radius in meters
 .fillColor(Color.TRANSPARENT)  //default
 .strokeColor(Color.BLUE)
 .strokeWidth(5);

 myCircle = myMap.addCircle(circleOptions);
 points.add(circleOptions);

}
