百度安卓地圖學習（三）

讀完後http://blog.csdn.net/woshishuoshuoa/article/details/9858417，接著看看這篇博文吧，這篇文章是將前倆篇的搜尋和定位進行了簡單地整合，並在點擊搜尋到的標誌處可以簡單地顯示所在位置的名稱。註：這裡的給出的代碼都是在之前的項目上新增的哦~~~

建立linemap.xml檔案：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <LinearLayout      android:layout_width="match_parent"    android:layout_height="wrap_content"    android:orientation="horizontal" >    <EditText         android:id="@+id/edit_linemap"         android:layout_width="wrap_content"         android:layout_height="match_parent"         android:layout_weight="1" />    <Button         android:id="@+id/btn1_linemap"        android:text="搜尋"         android:layout_width="wrap_content"         android:layout_height="match_parent"/>     <Button          android:id="@+id/btn2_linemap"         android:text="定位"         android:layout_width="wrap_content"         android:layout_height="match_parent"/></LinearLayout><LinearLayout     android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:orientation="horizontal"     >    <RadioButton        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="鹽城"       android:id="@+id/radio1"        />    <RadioButton         android:layout_width="match_parent"        android:layout_height="wrap_content"         android:text="上海"       android:id="@+id/radio2"        />    <RadioButton         android:layout_width="match_parent"       android:layout_height="wrap_content"        android:text="南京"       android:id="@+id/radio3"        /></LinearLayout><com.baidu.mapapi.map.MapView android:id="@+id/linemap_bmapsView"                      android:layout_width="fill_parent"                      android:layout_height="fill_parent"                      android:clickable="true" />  </LinearLayout>

建立pop_window_text.xml檔案：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:background="@drawable/popup" >    <TextView         android:id="@+id/tv_pop_window_item"        android:layout_width="wrap_content"        android:layout_height="39px"        android:text="Text"        android:textSize="16dp"        android:gravity="center"        android:background="#383838"        android:textColor="#fff"        /></LinearLayout>

建立activity代碼如下：

本文的例子比較小，存在一些小錯誤，還有待完善。。。不過會持續更新的哦~~~歡迎喜歡安卓的親們提出你們的寶貴意見哦~~~
