Android开中高德SDK通过经纬度实现路径规划

时间：2016-01-21 编辑：简简单单来源：一聚教程网

先看一下效果图:

1、刚进入时：

，默认为北京

2、点击“bus”按钮:

3、点击”car”按钮:

4、点击”walk”按钮

好了，接下来开始实现吧!

布局：

android:layout_width=”match_parent”

android:layout_height=”match_parent”

android:orientation=”vertical”>

android:layout_width=”match_parent”

android:layout_height=”wrap_content”>

android:id=”@+id/btn_bus”

android:layout_width=”0dp”

android:layout_height=”wrap_content”

android:layout_weight=”1″

android:onClick=”doClick”

android:text=”bus” />

android:id=”@+id/btn_car”

android:layout_width=”0dp”

android:layout_height=”wrap_content”

android:layout_weight=”1″

android:onClick=”doClick”

android:text=”car” />

android:id=”@+id/btn_walk”

android:layout_width=”0dp”

android:layout_height=”wrap_content”

android:layout_weight=”1″

android:onClick=”doClick”

android:text=”walk” />

ps.MapView

android:id=”@+id/map”

android:layout_width=”match_parent”

android:layout_height=”match_parent”>

功能:

好了，over，觉得有用的点个赞吧~

上一个： Android开发中EditText只能输入金额
下一个： Android通过滑动控制ListView的高度
