android 实践项目四
本周主要是开发android baidumap实现公交的查询
1、权限的取得和对屏幕的支持
<uses-permission android:name="android.permission.BAIDU_LOCATION_SERVICE" >
</uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" >
</uses-permission>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" >
</uses-permission>
<uses-permission android:name="android.permission.INTERNET" >

<!-- SDK1.5需要android.permission.GET_TASKS权限判断本程序是否为当前运行的应用? -->
<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.CAMERA" >
</uses-permission>

</uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

3、布局的实现.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" > <LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" > <TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="在" /> <EditText
android:id="@+id/city"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="北京" /> <TextView
android:layout_width="wrap_content"

android:id="@+id/searchkey"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="" /> <TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="公交车" /> <LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" > <Button
android:id="@+id/search"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="2dip"
android:layout_marginRight="2dip"
android:layout_weight=""
android:background="@drawable/button_style"
android:onClick="searchButtonProcess"
android:text="开始" /> <Button
android:id="@+id/nextline"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="2dip"
android:layout_marginRight="2dip"
android:layout_weight=""
android:background="@drawable/button_style"
android:onClick="SearchNextBusline"
android:text="下一条" />
</LinearLayout>
</LinearLayout> <RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" > <fragment
android:id="@+id/bmapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
class="com.baidu.mapapi.map.SupportMapFragment"
android:clickable="true" /> <LinearLayout

android:layout_alignParentBottom="true"
android:layout_alignWithParentIfMissing="false"
android:layout_centerHorizontal="true"
android:layout_centerVertical="false"
android:layout_marginBottom="10dip" > <Button
android:id="@+id/pre"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="2dip"
android:layout_marginRight="2dip"
android:layout_weight="1.0"
android:background="@drawable/pre_"
android:onClick="nodeClick" /> <Button
android:id="@+id/next"
android:layout_width="fill_parent"

android:layout_marginLeft="2dip"
android:layout_marginRight="2dip"
android:layout_weight="1.0"
android:background="@drawable/next_"
android:onClick="nodeClick" />
</LinearLayout>
</RelativeLayout> </LinearLayout>
4、默认的是北京83路公交
