android Google map使用总结

<uses-feature
        android:glEsVersion="0x00020000"
        android:required="true"/>

@Override
public void onCameraChange(CameraPosition arg0) {
	// TODO Auto-generated method stub
	zoom = arg0.zoom;
}

MarkerOptions markerOpt = new MarkerOptions();  
markerOpt.position(new LatLng(geoLat, geoLng));  
markerOpt.draggable(false);  
markerOpt.visible(true);  
markerOpt.anchor(0.5f, 0.5f);//设为图片中心  
markerOpt.icon(BitmapDescriptorFactory  
	.fromResource(R.drawable.sos_location_38x53));  
mMap.addMarker(markerOpt);  
//将摄影机移动到指定的地理位置  
cameraPosition = new CameraPosition.Builder()  
.target(new LatLng(geoLat, geoLng))              // Sets the center of the map to ZINTUN  
	.zoom(zoom)                  // 缩放比例  
	.bearing(0)                // Sets the orientation of the camera to east  
	.build();                  // Creates a CameraPosition from the builder  
mMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

6.实现地图圆角效果：使用圆角.9图片，中间透明，圆角四周不透明<br>
详细可以看这个提问：[Is there a way to implement rounded corners to a Mapfragment?](http://stackoverflow.com/questions/14469208/is-there-a-way-to-implement-rounded-corners-to-a-mapfragment)

7.去掉google地图自带的蓝色圆点
GoogleMap.setMyLocationEnabled(false);

8.解决mapview与scrollview嵌套滑动的问题：
思路就是使用getParent().requestDisallowInterceptTouchEvent(true);方法，让子类接收到touch事件

~~~ Java
public class MyMapView extends MapView {
    private ViewParent mViewParent;

    public MyMapView(Context context) {
        super(context);
    }

    public MyMapView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyMapView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public MyMapView(Context context, GoogleMapOptions options) {
        super(context, options);
    }


    public void setViewParent(@Nullable final ViewParent viewParent) { //any ViewGroup
        mViewParent = viewParent;
    }

    @Override
    public boolean onInterceptTouchEvent(final MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                if (null == mViewParent) {
                    //设置父类不拦截touch事件，子view可以接收到touch事件
                    getParent().requestDisallowInterceptTouchEvent(true);
                } else {
                    mViewParent.requestDisallowInterceptTouchEvent(true);
                }
                break;
            case MotionEvent.ACTION_UP:
                if (null == mViewParent) {
                    //让父类拦截touch事件
                    getParent().requestDisallowInterceptTouchEvent(false);
                } else {
                    mViewParent.requestDisallowInterceptTouchEvent(false);
                }
                break;
            default:
                break;
        }

        return super.onInterceptTouchEvent(event);
    }
}

@Override
public void onProviderDisabled(String provider) {
    isLocatedSuccess = false;
    if (provider.equals("network")) //跳到位置服务设置页面
        startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
}
