ArcGIS For Android 之客户端添加要素（130412）

ArcGIS Android 中提供了一个客户端的要素图层GraphicsLayer 。今天就把，那些添加不同要素的范例或者Api进行归纳一下。（技术声明：由于本人技术有限，有疏漏和错误的地方请留言纠正！）



1 . 首先做一个给地图图层增加一个点：

代码范例是在设置地图单击监听中进行实现：

final GraphicsLayer graphicsLayer = new GraphicsLayer();
mMapView.addLayer(graphicsLayer);
mMapView.setOnSingleTapListener(new OnSingleTapListener() {
public void onSingleTap(float x, float y) {
// TODO Auto-generated method stub
//实现点击地图，添加一个红色的点
Graphic graphic = new Graphic(mMapView.toMapPoint(x, y),
new SimpleMarkerSymbol(Color.RED, 15, STYLE.CIRCLE));
graphicsLayer.addGraphic(graphic);
Log.v(TAG, "add simpleMarker");

}
});

实现的效果图：



2.然后用PictureMakerSymbol给图增加图片：

代码范例是在设置地图单击监听中进行实现：

final GraphicsLayer graphicsLayer = new GraphicsLayer();
mMapView.addLayer(graphicsLayer);
mMapView.setOnSingleTapListener(new OnSingleTapListener() {
public void onSingleTap(float x, float y) {
// TODO Auto-generated method stub

Resources res = getResources();
Drawable drawable = res.getDrawable(R.drawable.jtjq_01);
Graphic graphic = new Graphic(mMapView.toMapPoint(x, y),
new PictureMarkerSymbol(drawable));
graphicsLayer.addGraphic(graphic);
Log.v(TAG, "add simpleMarker");

}
});
