我在尝试像Android Java中的setTimeout()这样的动画时遇到了一些问题。我有一个几何列表,我想一次一个地绘制到地图上:
public void getDirection(Event eventModel, final Context context) {
String eventX = eventModel.getEventX();
String eventY = eventModel.getEventY();
//Code to get data geometry data from API and store in pathGeometries
final Drawable d = EventDrawableImage.resizeCurrentLocImage("current_loc",
context);
for (int iii = 0; iii < pathGeometries.size(); iii++) {
final int counter = iii ;
EventDetail.handler.postDelayed(new Runnable()
{
private long time = 0;
public void run()
{
time += 1000;
EventDetail.handler.postDelayed(this, 1000);
moveNext(pathGeometries.get(counter).getX(),
pathGeometries.get(counter).getY(), 0, d);
}
}, 1000);
}
}
public static void moveNext(double coordx, double coordy, int k, Drawable d){
//EventMain.mMapView.removeAll();
// Set center
Point p = new Point(coordx, coordy);
EventMain.mMapView.zoomToResolution(p, 1);
// Add marker
PictureMarkerSymbol graphicIcon;
graphicIcon = new PictureMarkerSymbol(d);
Symbol symbol = graphicIcon;
HashMap<String, Object> attrMap = new HashMap<String, Object>();
attrMap.put("currentLoc", "User Current location");
EventMain.graphicsLayer.addGraphic(new Graphic(p, symbol, attrMap));
}
我现在遇到的问题是路径几何传递到moveNext()的每个点,它在移动到另一个点之前不会保持20秒。相反,它只是一直循环直到结束,而不是在每个点停止。
有什么想法吗?提前谢谢。

不确定我是否理解正确的意图,但尝试这样的事情:
long time = 0;
for (int iii = 0; iii < pathGeometries.size(); iii++) {
final int counter = iii;
time += 1000;
EventDetail.handler.postDelayed(new Runnable() {
@Override
public void run() {
moveNext(pathGeometries.get(counter).getX(),
pathGeometries.get(counter).getY(), 0, d);
}
}, time);
}

也许循环并使用循环索引来建立延迟时间。
for (int iii = 0; iii < pathGeometries.size(); iii++) {
EventDetail.handler.postDelayed(new Runnable()
{
public void run()
{
moveNext(pathGeometries.get(counter).getX(),
pathGeometries.get(counter).getY(), 0, d);
}
}, 1000 *(iii+1));
}
