百度地图:建立百度地图开发环境)

今天开始写安卓的博客啦，这次给大家带来的是安卓版本的百度地图的开发

在正式开始之前先请大家注意，在转载博客的时候注意说明出处 

在做百度地图开发的时候第一步肯定是要搭建好安卓的开发环境，由于面向的并不是刚入门，或者说是还没有入门的初级开发者，所以这里的环境搭建我就不跟大家细说了

安卓环境搭建请移步-->百度文库

下面就正式开始写在安卓上面如何利用百度地图开发应用

第一步：下载百度的官方文档-->移步百度API文档下载这次教程使用的版本为《Android SDKv1.3.5（栅格地图版）全部文档下载》

第二步：到百度的官方网站申请百度不用于商业用途的KEY-->移步申请KEY

第三步：等我们的KEY和文档都下载好了以后就可以正式开始编写我们的代码了（建立如下的项目）

第四步：在上图项目中的资源定义文件中（AndroidManifest.xml）加入如下代码

<!-- 添加百度API的授权信息 -->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
    <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
    <uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

<!-- 添加百度API的授权信息 -->
	<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
	<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
	<uses-permission android:name="android.permission.INTERNET"></uses-permission>
	<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
	<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>  
	<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission> 
	<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
	<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

第五步：添加百度地图对屏幕的支持同样是在资源定义文件中

<!-- 添加百度地图对屏幕的支持 -->
     <supports-screens android:largeScreens="true"
        android:normalScreens="false" android:smallScreens="true"
        android:resizeable="true" android:anyDensity="true"/>

<!-- 添加百度地图对屏幕的支持 -->
	 <supports-screens android:largeScreens="true"
	    android:normalScreens="false" android:smallScreens="true"
	    android:resizeable="true" android:anyDensity="true"/>

资源：资源定义文件全部内容如下

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.shuaiyin.baidu"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="10" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".BaiDu_SuYiActivity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <!-- 添加百度API的授权信息 -->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

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

     <!-- 添加百度地图对屏幕的支持 -->
     <supports-screens android:largeScreens="true"
        android:normalScreens="false" android:smallScreens="true"
        android:resizeable="true" android:anyDensity="true"/>
</manifest>

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.shuaiyin.baidu"
    android:versionCode="1"

    <uses-sdk android:minSdkVersion="10" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".BaiDu_SuYiActivity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
	<!-- 添加百度API的授权信息 -->
	<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
	<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
	<uses-permission android:name="android.permission.INTERNET"></uses-permission>
	<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

	<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
	<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>
	
	 <!-- 添加百度地图对屏幕的支持 -->
	 <supports-screens android:largeScreens="true"
	    android:normalScreens="false" android:smallScreens="true"
	    android:resizeable="true" android:anyDensity="true"/>
</manifest>

第六部：把百度地图的JAR包全部导入到项目当中

在百度官方给出的示例文档《BaiduMapApi_Sample_Android_1.3.5》中复制如下图给出的文件注意要在Jar包上点击右键Build Path --> Add to Build Path

第七步：在main.xml中定义显示百度地图控件的MAP

<!-- 添加显示百度地图的控件 -->
     <com.baidu.mapapi.MapView
        android:id="@+id/bmapView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"/>

<!-- 添加显示百度地图的控件 -->
     <com.baidu.mapapi.MapView 
        android:id="@+id/bmapView"
		android:layout_width="fill_parent" 
		android:layout_height="fill_parent" 
		android:clickable="true"/>

    资源:main.xml中全部的代码

<?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" >

    <!-- 添加显示百度地图的控件 -->
     <com.baidu.mapapi.MapView
        android:id="@+id/bmapView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"/>

</LinearLayout>

<?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" >

    <!-- 添加显示百度地图的控件 -->
     <com.baidu.mapapi.MapView 
        android:id="@+id/bmapView"
		android:layout_width="fill_parent" 
		android:layout_height="fill_parent" 
		android:clickable="true"/>

</LinearLayout>

第八步：这样环境就基本搭建好了，下面就开始写代码了主要在BaiDu_SuYiActivity.java中间完成

1.让  BaiDu_SuYiActivity  继承百度地图提供的   MapActivity  (com.baidu.mapapi.MapActivity)

2.添加对百度地图相关控件的定义

<SPAN style="WHITE-SPACE: pre"> </SPAN>//添加百度地图的相关控件
<SPAN style="WHITE-SPACE: pre"> </SPAN>private MapView mapView;
<SPAN style="WHITE-SPACE: pre"> </SPAN>//加载百度地图的引起
<SPAN style="WHITE-SPACE: pre"> </SPAN>private BMapManager bMapManager;
<SPAN style="WHITE-SPACE: pre"> </SPAN>//定义百度地图的KEY
<SPAN style="WHITE-SPACE: pre"> </SPAN>private String key = "*我对KEY做了处理*729DD94B0429A4BEE30797E04D91B0211C4";
<SPAN style="WHITE-SPACE: pre"> </SPAN>//在百度地图上添加相应的控件
<SPAN style="WHITE-SPACE: pre"> </SPAN>private MapController mapController;

	//添加百度地图的相关控件
	private MapView mapView;
	//加载百度地图的引起
	private BMapManager bMapManager;
	//定义百度地图的KEY
	private String key = "*我对KEY做了处理*729DD94B0429A4BEE30797E04D91B0211C4";
	//在百度地图上添加相应的控件
	private MapController mapController;

3.在继承MapActivity时要实现他下面的一个方法

<SPAN style="WHITE-SPACE: pre"> </SPAN>@Override
    protected boolean isRouteDisplayed() {
        return false;
    }

	@Override
	protected boolean isRouteDisplayed() {
		return false;
	}

4.在onCreate方法中写入如下代码

<SPAN style="WHITE-SPACE: pre"> </SPAN>//首先实例化mapView
        mapView = (MapView) this.findViewById(R.id.bmapView);
        bMapManager = new BMapManager(BaiDu_SuYiActivity.this);
        //调用百度地图加载KEY
        bMapManager.init(key, new MKGeneralListener() {

            @Override
            public void onGetPermissionState(int arg0) {
                if(arg0 == 300){
                    Toast.makeText(BaiDu_SuYiActivity.this, "您输入的KEY有问题,请核实", 2).show();
                }
            }

            @Override
            public void onGetNetworkState(int arg0) {

            }
        });

        this.initMapActivity(bMapManager);
        //表示可以设置缩放功能
        mapView.setBuiltInZoomControls(true);
        mapController = mapView.getController();
        //在百度地图上标注一个中心点
        GeoPoint geoPoint = new GeoPoint((int)(39.915*1E6),(int)(116.404*1E6));
        //给地图对象设置一个中心点
        mapController.setCenter(geoPoint);
        //设置地图的缩放级别
        mapController.setZoom(12);

	//首先实例化mapView
        mapView = (MapView) this.findViewById(R.id.bmapView);
        bMapManager = new BMapManager(BaiDu_SuYiActivity.this);
        //调用百度地图加载KEY
        bMapManager.init(key, new MKGeneralListener() {
			
			@Override
			public void onGetPermissionState(int arg0) {
				if(arg0 == 300){
					Toast.makeText(BaiDu_SuYiActivity.this, "您输入的KEY有问题,请核实", 2).show();
				}
			}
			
			@Override
			public void onGetNetworkState(int arg0) {
				
			}
		});
        
        this.initMapActivity(bMapManager);
        //表示可以设置缩放功能
        mapView.setBuiltInZoomControls(true);
        mapController = mapView.getController();
        //在百度地图上标注一个中心点
        GeoPoint geoPoint = new GeoPoint((int)(39.915*1E6),(int)(116.404*1E6));
        //给地图对象设置一个中心点
        mapController.setCenter(geoPoint);
        //设置地图的缩放级别
        mapController.setZoom(12);

5.最后实现

onDestroy()-->onResume()-->onPause()方法

@Override
    protected void onDestroy() {
        super.onDestroy();
        if(bMapManager != null){
            bMapManager.destroy();
            bMapManager = null;
        }
    }
    @Override
    protected void onResume() {
        super.onResume();
        if(bMapManager != null){
            bMapManager.start();
        }
    }
    @Override
    protected void onPause() {
        super.onPause();
        if(bMapManager != null){
            bMapManager.stop();
        }
    }

@Override
    protected void onDestroy() {
    	super.onDestroy();
    	if(bMapManager != null){
    		bMapManager.destroy();
    		bMapManager = null;
    	}
    }
    @Override
    protected void onResume() {
    	super.onResume();
    	if(bMapManager != null){
    		bMapManager.start();
    	}
    }
    @Override
    protected void onPause() {
    	super.onPause();
    	if(bMapManager != null){
    		bMapManager.stop();
    	}
    }

<SPAN style="WHITE-SPACE: pre"></SPAN>

模拟器中运行的结果

最后，这样就完成了，是不是用百度地图开发APP是一件很简单的事情呢！只要肯努力就没有什么搞不定的。跟我一起走向移动开发把。
