核心代码
1.步行路线规划结果解析
JAVA
/**
* 设置路线数据。
*
* @param line 路线数据
*/
public void setData(WalkingRouteLine line) {
mRouteLine = line;
}
@Override
public final List<OverlayOptions> getOverlayOptions() {

return null;
}

&& mRouteLine.getAllStep().size() > 0) {
for (WalkingRouteLine.WalkingStep step: mRouteLine.getAllStep()) {

if (step.getEntrance()!= null) {
overlayList.add((new MarkerOptions()).position(step.getEntrance().getLocation())
.rotate((360 - step.getDirection())).zIndex(10).anchor(0.5f, 0.5f)
.extraInfo(b)
.icon(BitmapDescriptorFactory.fromAssetWithDpi("Icon_line_node.png")));
}
// 最后路段绘制出口点

// starting

// poly line list

public final void addToMap() {
if (mBaiduMap == null) {
return;
}
List<OverlayOptions> overlayOptions = getOverlayOptions();
if (overlayOptions!= null) {
mOverlayOptionList.addAll(getOverlayOptions());
}
for (OverlayOptions option: mOverlayOptionList) {

3.将步行路线调整到地图显示的最佳视野范围内
JAVA
/**
* 将步行路线调整到地图显示的最佳视野范围内
*/
public void zoomToSpanPaddingBounds(int paddingLeft, int paddingTop, int paddingRight,
int paddingBottom) {
if (mBaiduMap == null) {
return;
}
if (mOverlayList.size() > 0) {
LatLngBounds.Builder builder = new LatLngBounds.Builder();
for (Overlay overlay: mOverlayList) {
// polyline 中的点可能太多，只按marker 缩放
if (overlay instanceof Marker) {
builder.include(((Marker) overlay).getPosition());
}
}
mBaiduMap.setMapStatus(MapStatusUpdateFactory
.newLatLngBounds(builder.build(), paddingLeft, paddingTop, paddingRight,
paddingBottom));
}
