以下代码可帮助您在内置MAP中显示路线：

String fullAddress = "Your full address";

//Using address
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?f=d&daddr=" + fullAddress));

//Using Latitude,Longitude
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?f=d&daddr=51.448,-0.972"));

intent.setComponent(new ComponentName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity"));

startActivity(intent);

您可以在图像视图中使用两个地理点之间路线的地图截图。这是在两个地理点之间绘制路线的一个很好的示例 http://wptrafficanalyzer.in/blog/drawing-driving-route-directions-between-two-locations-using-google-directions-in-google-map-android-api-v2/
