我创建了2个onTapEvent监听器，通过单击不同的按钮将不同图标的标记添加到我的地图中。但是，我只能添加1种类型的标记，第二个按钮（添加人群）会在我点击它之后崩溃我的应用程序。
以下是我的按钮代码示例：
设定目的地：
private void initAddDestinationButton() {
m_setDetinationButton = (Button) findViewById(R.id.setDestinationButton);
m_setDetinationButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
/*
* Clear map if previous results are still on map,otherwise proceed to creating
* route
*/
if (map != null && m_mapRoute != null) {
map.removeMapObject(m_mapRoute);
m_mapRoute = null;
} else
{
addDestination();
}
}
});
}
private void addDestination() {
if (destinationMarker == null) {
image = new Image();
try {
image.setImageResource(R.drawable.letterx);
} catch (final IOException e) {
e.printStackTrace();
}
}
mapFragment.getMapGesture().removeOnGestureListener(addCrowdListener2);
mapFragment.getMapGesture().addOnGestureListener(setDestinationListener2, 1, true);
}
添加人群：
private void initAddCrowdButton() {
m_addCrowdButton = (Button) findViewById(R.id.addCrowdButton);
m_addCrowdButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view2) {
if (map != null && m_mapRoute != null) {
map.removeMapObject(m_mapRoute);
m_mapRoute = null;
} else
{
addCrowd();
}
}
});
}
private void addCrowd() {
if (blocked == null) {
image2 = new Image();
try {
image.setImageResource(R.drawable.marker);
} catch (final IOException e) {
e.printStackTrace();
}
}
mapFragment.getMapGesture().removeOnGestureListener(setDestinationListener2);
mapFragment.getMapGesture().addOnGestureListener(addCrowdListener2, 10, true);
}
以下是我声明的2个onTapEvent侦听器：
private MapGesture.OnGestureListener addCrowdListener2 = new MapGesture.OnGestureListener.OnGestureListenerAdapter() {
@Override
public boolean onTapEvent(PointF pointF) {
GeoCoordinate e = map.pixelToGeo(pointF);
MapMarker b = new MapMarker(e, image2);
blockList.add(b);
b.setAnchorPoint(new PointF(image.getWidth()/2, image.getHeight()));
map.addMapObject(b);
blocked = blockList.get(blockList.size() - 1);
blockedPath = blocked.getCoordinate();
blockedRoad = RoadElement.getRoadElement(blockedPath, "eng" );
return super.onTapEvent(pointF);
}
};
private MapGesture.OnGestureListener setDestinationListener2 = new MapGesture.OnGestureListener.OnGestureListenerAdapter() {
@Override
public boolean onTapEvent(PointF pointF) {
GeoCoordinate endpoint = map.pixelToGeo(pointF);
MapMarker m = new MapMarker(endpoint,image);
markerList.add(m);
m.setAnchorPoint(new PointF(image.getWidth()/2, image.getHeight()));
map.addMapObject(m);
destinationMarker = markerList.get(markerList.size() - 1);
destination = destinationMarker.getCoordinate();
return super.onTapEvent(pointF);
}
};
我已经在OnEngineInitiaizatioCompleted()内宣布了按钮。到目前为止，只有Set Destination按钮正常运行。单击Add Crowd将使我的应用程序崩溃（在单击Set Destination之前和之后单击它，单击时崩溃应用程序）
这是崩溃的堆栈跟踪：

我认为您的资源R.drawable.marker无法由SDK呈现。它是什么样的图像资源？仅支持位图资源。
