Android百度地圖應(yīng)用之創(chuàng)建顯示地圖

 更新時(shí)間：2016年06月13日 15:45:33   作者：rainmj  
這篇文章主要為大家詳細(xì)介紹了Android百度地圖應(yīng)用之創(chuàng)建顯示地圖，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文是在完成了Android百度地圖應(yīng)用開(kāi)發(fā)基礎(chǔ)知識(shí)的基礎(chǔ)上繼續(xù)實(shí)現(xiàn)的。

本文實(shí)例為大家分享了Android如何顯示地圖，并為后續(xù)內(nèi)容做準(zhǔn)備，供大家參考，具體內(nèi)容如下

 1、運(yùn)行效果
 本章共有25個(gè)示例，在x86模擬器中運(yùn)行的效果如下：

 

下面介紹主要設(shè)計(jì)步驟。

 2、添加資源
 （1）drawable-hdpi 
Resources/ drawable-hdpi下的文件：將下載的示例對(duì)應(yīng)文件夾下的文件全部拖放到該文件夾下，并將所有【生成操作】屬性全部設(shè)置為“AndroidResource”。 
（2）layout 
Resources/layout下的文件：該文件夾下的所有文件的【生成操作】屬性全部為“AndroidResource”。后續(xù)的各節(jié)示例中再逐步向該文件夾下添加文件，這是為了讓你明白每個(gè)例子對(duì)應(yīng)的是哪個(gè)布局文件。
（3）raw 
Resources/raw下的文件：將下載的示例對(duì)應(yīng)文件夾下的文件全部拖放到該文件夾下，并確認(rèn)【生成操作】屬性設(shè)為“AndroidResource”。 
（4）values
 Resources/values下的文件：將下載的示例對(duì)應(yīng)文件夾下的文件全部拖放到該文件夾下，并將所有【生成操作】屬性全部設(shè)為“AndroidResource”。 

3、在layout下添加HelloBdMap.axml文件
 在layout文件夾下添加該文件，將其改為下面的代碼：

<?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">
 <com.baidu.mapapi.map.TextureMapView
 android:id="@+id/bmapView"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:clickable="true" />
</LinearLayout>

4、在根目錄下添加HelloBaiduMap.cs文件
 將該文件改為下面的代碼： 

using Android.App;
using Android.Content.PM;
using Android.OS;
using Com.Baidu.Mapapi.Map;

namespace BdMapV371Demos
{
 [Activity(Label = "BdMapV371Demos", MainLauncher = false,
 ConfigurationChanges = ConfigChanges.Orientation,
 ScreenOrientation = ScreenOrientation.Sensor,
 Icon = "@drawable/icon")]
 public class HelloBaiduMap : Activity
 {
 private TextureMapView mMapView;
 protected override void OnCreate(Bundle bundle)
 {
  base.OnCreate(bundle);
  SetContentView(Resource.Layout.HelloBdMap);
  mMapView = FindViewById<TextureMapView>(Resource.Id.bmapView);
 }

 protected override void OnPause()
 {
  base.OnPause();
  mMapView.OnPause();
 }

 protected override void OnResume()
 {
  base.OnResume();
  mMapView.OnResume();
 }

 protected override void OnDestroy()
 {
  base.OnDestroy();
  mMapView.OnDestroy();
 }
 }
}

5、修改Main.axml文件
 將該文件改為下面的內(nèi)容： 

<?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="wrap_content"
 android:orientation="vertical">
 <TextView
 android:id="@+id/text_Info"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:textSize="14sp" />
 <View
 android:layout_width="fill_parent"
 android:layout_height="1dip"
 android:background="?android:attr/listDivider" />
 <ListView
 android:id="@+id/listView"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content" />
</LinearLayout>

6、添加DemoApplication.cs文件
 在項(xiàng)目的根文件夾下添加該文件。 

using System;
using Android.App;
using Android.Runtime;
using Com.Baidu.Mapapi;
namespace BdMapV371Demos
{
 [Application]
 public class DemoApplication : Application
 {
 public DemoApplication(IntPtr javaReference, JniHandleOwnership transfer)
  : base(javaReference, transfer)
 {
 }

 public override void OnCreate()
 {
  base.OnCreate();
  // 在使用 SDK 各組間之前初始化 context 信息，傳入 ApplicationContext
  SDKInitializer.Initialize(ApplicationContext);
 }
 }
}

7、添加SDKReceiver.cs文件
 在項(xiàng)目的根文件夾下添加該文件。 

using Android.Content;
using Android.Graphics;
using Android.Util;
using Android.Widget;
using Com.Baidu.Mapapi;
namespace BdMapV371Demos
{
 /// <summary>
 /// 廣播監(jiān)聽(tīng)類(lèi)，監(jiān)聽(tīng) SDK key 驗(yàn)證以及網(wǎng)絡(luò)異常廣播
 /// </summary>
 [BroadcastReceiver]
 public class SDKReceiver : BroadcastReceiver
 {
 private static readonly string LTAG = nameof(MainActivity);
 private MainActivity bMapApiDemoMain;

 public SDKReceiver()
 {
 }

 public SDKReceiver(MainActivity bMapApiDemoMain)
  : base()
 {
  this.bMapApiDemoMain = bMapApiDemoMain;
 }

 public override void OnReceive(Context context, Intent intent)
 {
  string s = intent.Action;
  Log.Debug(LTAG, "action: " + s);
  TextView text = bMapApiDemoMain.FindViewById<TextView>(Resource.Id.text_Info);
  text.SetTextColor(Color.Red);
  switch(s)
  {
  case SDKInitializer.SdkBroadtcastActionStringPermissionCheckError:
   text.Text = "key 驗(yàn)證出錯(cuò)! 請(qǐng)?jiān)?AndroidManifest.xml 文件中檢查 key 設(shè)置";
   break;
  case SDKInitializer.SdkBroadtcastActionStringPermissionCheckOk:
   text.Text += ",key驗(yàn)證成功!";
   text.SetTextColor(Color.Yellow);
   break;
  case SDKInitializer.SdkBroadcastActionStringNetworkError:
   text.Text = "網(wǎng)絡(luò)出錯(cuò)";
   break;
  }
 }
 }
}

8、修改String.xml文件

10、運(yùn)行 
按<F5>調(diào)試運(yùn)行，在主界面中單擊【Hello BaiduMap】，觀察效果。
 注意：本章后面介紹的所有例子都是在這一節(jié)例子的基礎(chǔ)上繼續(xù)修改完成的。這樣做的目的是為了在同一個(gè)項(xiàng)目中演示多個(gè)示例，而不是一個(gè)項(xiàng)目?jī)H包含一個(gè)示例，這樣可避免必須申請(qǐng)多個(gè)密鑰的麻煩。
 要確保該例子在你的模擬器上運(yùn)行沒(méi)問(wèn)題，才能繼續(xù)學(xué)習(xí)后續(xù)的demo。

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
