先讲一下路径规划的主要函数：

说明：city为待查公交线路所在城市，start和end分别是起点和终点

驾车路线搜索：mMKSearch.drivingSearch(null, start, null, end)；

步行线路搜索：mMKSearch.walkingSearch(null, start, null, end)；

公交线路搜索的方法：transitSearch(String city, MKPlanNode start, MKPlanNode end)，city；

另外，公交和驾车的策略：

其他的可以看百度官网。

我的应用代码实例如下：（以公交方式为例）

if (mBtnTransit.equals(v)) {
			//单击搜索后，关闭软键盘
			InputMethodManager imm=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
			imm.hideSoftInputFromWindow(editEn.getWindowToken(), 0);
			
			if(stNode.name.equals("")){
				Toast toast=Toast.makeText(RoutePlan.this, "您的起点输入为空！", Toast.LENGTH_LONG);
    			toast.setGravity(Gravity.CENTER, 0, 0);
    			toast.show();
			}else if(enNode.name.equals("")){
				Toast toast=Toast.makeText(RoutePlan.this, "您的终点输入为空！", Toast.LENGTH_LONG);
    			toast.setGravity(Gravity.CENTER, 0, 0);
    			toast.show();
			}else{
				mBtnDrive.setClickable(false);
				mBtnDrive.setTextColor(Color.GRAY);
				mBtnWalk.setClickable(false);
				mBtnWalk.setTextColor(Color.GRAY);
				bus_mintime.setVisibility(View.VISIBLE);
		    	bus_minexchange.setVisibility(View.VISIBLE);
		    	bus_minwalk.setVisibility(View.VISIBLE);
		        
		    	bus_mintime.setOnClickListener(new OnClickListener(){
					@Override    //公交时间优先
					public void onClick(View arg0) {
						mSearch.setTransitPolicy(MKSearch.EBUS_TIME_FIRST);
						mSearch.transitSearch("赣州市", stNode, enNode);
						Log.i("bus search","EBUS_TIME_FIRST");
						dialog.show();
						
						bus_mintime.setVisibility(View.GONE);
				    	bus_minexchange.setVisibility(View.GONE);
				    	bus_minwalk.setVisibility(View.GONE);
				    	mBtnDrive.setClickable(true);
						mBtnDrive.setTextColor(Color.BLUE);
						mBtnWalk.setClickable(true);
						mBtnWalk.setTextColor(Color.BLUE);
					}
		    	});
		    	bus_minexchange.setOnClickListener(new OnClickListener(){
					@Override    //公交最少换乘
					public void onClick(View arg0) {
						mSearch.setTransitPolicy(MKSearch.EBUS_TRANSFER_FIRST);
						mSearch.transitSearch("赣州市", stNode, enNode);
						Log.i("bus search","EBUS_TRANSFER_FIRST");
						dialog.show();
						
						bus_mintime.setVisibility(View.GONE);
				    	bus_minexchange.setVisibility(View.GONE);
				    	bus_minwalk.setVisibility(View.GONE);
				    	mBtnDrive.setClickable(true);
						mBtnDrive.setTextColor(Color.BLUE);
						mBtnWalk.setClickable(true);
						mBtnWalk.setTextColor(Color.BLUE);
					}
		    	});
		    	bus_minwalk.setOnClickListener(new OnClickListener(){
					@Override    //公交最少步行
					public void onClick(View arg0) {
						mSearch.setTransitPolicy(MKSearch.EBUS_WALK_FIRST);
						mSearch.transitSearch("赣州市", stNode, enNode);
						Log.i("bus search","EBUS_WALK_FIRST");
						dialog.show();
						
						bus_mintime.setVisibility(View.GONE);
				    	bus_minexchange.setVisibility(View.GONE);
				    	bus_minwalk.setVisibility(View.GONE);
				    	mBtnDrive.setClickable(true);
						mBtnDrive.setTextColor(Color.BLUE);
						mBtnWalk.setClickable(true);
						mBtnWalk.setTextColor(Color.BLUE);
					}
		    	});
			}

效果如图：
