安卓部分编译器使用AS进行开发
使用友好的流线式布局进行开发
布局代码如下:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="10dp" android:paddingLeft="10dp" android:paddingRight="10dp" android:paddingTop="30dp" android:orientation="vertical" tools:context=".MainActivity" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="请选择站点线路起点线" /> <LinearLayout android:layout_width="match_parent" android:layout_height="141dp" android:layout_gravity="center" android:orientation="vertical"> <Spinner android:id="@+id/spinner1" android:layout_width="match_parent" android:layout_height="50dp" /> <Spinner android:id="@+id/spinner2" android:layout_width="match_parent" android:layout_height="50dp" android:layout_marginTop="20dp" /> </LinearLayout> <TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="请选择站点线路终点线" /> <LinearLayout android:layout_width="match_parent" android:layout_height="141dp" android:layout_gravity="center" android:orientation="vertical"> <Spinner android:id="@+id/spinner3" android:layout_width="match_parent" android:layout_height="50dp" /> <Spinner android:id="@+id/spinner4" android:layout_width="match_parent" android:layout_height="50dp" android:layout_marginTop="20dp" /> </LinearLayout> <Button android:id="@+id/searchButton" android:layout_width="match_parent" android:layout_height="40dp" android:text="搜索最短路线"> </Button> <TextView android:id="@+id/showShortestPath" android:layout_width="match_parent" android:layout_height="match_parent" android:text=""> </TextView> </LinearLayout>对与spinner（下拉框的集联操作使用xml进行了储存）
当选中相应的station值时进行选择第二个spinner中的应该显示的值
格式如下
<?xml version="1.0" encoding="utf-8"?> <resources> <string-array> <item>-站点线路-</item> <item>1</item> <item>2</item> <item>3</item> <item>5</item> <item>6</item> <item>9</item> </string-array> <string-array> <item>-站点-</item> <item>刘园</item> <item>西横堤</item> <item>果酒厂</item> <item>本溪路</item> <item>勤俭道</item> <item>洪湖里</item> <item>西站</item> <item>西北角</item> <item>西南角</item> <item>二纬路</item> <item>海光寺</item> <item>鞍山道</item> <item>营口道</item> <item>小白楼</item> <item>下瓦房</item> <item>南楼</item> <item>土城</item> <item>陈塘庄</item> <item>复兴门</item> <item>华山里</item> <item>财经大学</item> <item>双林</item> <item>李楼</item> </string-array> ...... </resources>
