Question

我想在活动中使用Map。

enter image description here 现在我解释整个问题。我有一个活动，在其中我想显示两种类型的地图

按钮橙色映射活动顶部的任何位置
按钮蓝色在活动顶部的两个点之间绘制折线

我完成了两项任务，但

按钮1 可以通过扩展带有活动的课程来显示任何位置的bsz地图

   public class Map_current_Location extends Activity { 
            // Google Map
            private GoogleMap googleMap;
            @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

    try {
        // Loading map
        initilizeMap();

        googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        // Showing / hiding your current location
        googleMap.setMyLocationEnabled(true);

        // Enable / Disable zooming controls
        googleMap.getUiSettings().setZoomControlsEnabled(false);

        // Enable / Disable my location button
        googleMap.getUiSettings().setMyLocationButtonEnabled(true);

        // Enable / Disable Compass icon
        googleMap.getUiSettings().setCompassEnabled(true);

        // Enable / Disable Rotate gesture
        googleMap.getUiSettings().setRotateGesturesEnabled(true);

        // Enable / Disable zooming functionality
        googleMap.getUiSettings().setZoomGesturesEnabled(true);

        double latitude = 31.510586;
        double longitude = 74.341245;

            // Adding a marker
            MarkerOptions marker = new MarkerOptions().position(
                    new LatLng(latitude, longitude))
                    .title("Hello Maps ");


            // changing marker color

                marker.icon(BitmapDescriptorFactory
                        .defaultMarker(BitmapDescriptorFactory.HUE_ROSE));


            googleMap.addMarker(marker);

            // Move the camera to last position with a zoom level

                CameraPosition cameraPosition = new CameraPosition.Builder()
                .target(new LatLng(latitude,
                        longitude)).zoom(30).build();

                googleMap.animateCamera(CameraUpdateFactory
                        .newCameraPosition(cameraPosition));



    } catch (Exception e) {
        e.printStackTrace();
    }

}

@Override
protected void onResume() {
    super.onResume();
    initilizeMap();
}

/**
 * function to load map If map is not created it will create it for you
 * */
private void initilizeMap() {
    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMap();

        // check if map is created successfully or not
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
        }
    }
}

但不能使用第二个按钮，因为折线和距离只能通过使用

public class Maps extends FragmentActivity实现OnClickListener

请建议我如何在一个活动中完成两个任务请告诉我是否可以通过子类来完成..

整个活动的XML

Answer 1

您好请扩展FragmentActivity，因为它也是扩展Activity。

使用一个xml进行两项活动
