前頁:這裏用到的sdk包就不介紹了在百度api裏面去下載就好了,然後就正式看對mapview的使用以及拖動地圖控件時候對地圖中間的紅色箭頭的處理。
1.先看下當前頁面的佈局文件:R.layout.activity_more_address,由一個mapview和listview組成,上面的編輯框是由AutoCompleteTextView自動提示輸入框組成。
<?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:background="@color/white"
android:clipToPadding="false"
android:fitsSystemWindows="true"
android:orientation="vertical" >
<RelativeLayout
android:id="@+id/rl_search"
android:layout_width="match_parent"
android:layout_height="45dp"
android:background="@color/tab" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="30dp"
android:layout_centerInParent="true"
android:layout_marginLeft="6dp"
android:layout_marginRight="12dp"
android:layout_marginTop="6dp"
android:layout_toRightOf="@+id/iv_left"
android:background="@color/bg_mine" >
<ImageView
android:id="@+id/iv_search"
android:layout_width="26dp"
android:layout_height="26dp"
android:layout_centerVertical="true"
android:layout_marginLeft="6dp"
android:paddingRight="6dp"
android:src="@drawable/search_icon_blac" />
<AutoCompleteTextView
android:id="@+id/et_search"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_toRightOf="@+id/iv_search"
android:background="@color/bg_mine"
android:gravity="center_vertical"
android:hint="請輸入您的收貨地址"
android:paddingLeft="2dp"
android:singleLine="true"
android:textColor="@color/black"
android:textSize="14sp" />
</RelativeLayout>
<ImageView
android:id="@+id/iv_left"
style="@style/head_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="6dp"
android:padding="14dp"
android:src="@drawable/arrow_left" />
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="280dp"
android:orientation="vertical"
android:visibility="visible" >
<com.baidu.mapapi.map.MapView
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white"
android:onClick="true" >
</com.baidu.mapapi.map.MapView>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="@color/transparent"
android:src="@drawable/gps_red" />
</RelativeLayout>
<ListView
android:id="@+id/lv_near_address"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:cacheColorHint="#00000000"
android:descendantFocusability="beforeDescendants"
android:fastScrollEnabled="true"
android:scrollbars="none" />
</LinearLayout>
2.然後就是拖動的地址活動界面MoreAddressActivity，拖動地圖的時候中間的紅色gps箭頭指向當前的地址，下面的listview會根據當前經緯度反地理編碼拿到附近的地址列表，第一個當然顯示的是gps箭頭所指向位置，點擊listview中的item之後，會返回所要拿到的地圖位置。
