安卓调用百度地图实现

本文将讲述安卓调用百度地图的实现方法，刚接触百度地图的童鞋可以作为参考，先看效果图：

 

 

再看工程文件：

注意，该项目所用百度sdk为最新版，需用最新密钥，再次声明，那些在调用百度地图时老是不正常的童鞋，一定要根据你的sdk版本申请对应密钥，这个我已经在上一篇文章中讲过了，大家可以去参考下。

首先看，主界面布局：

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <FrameLayout        android:layout_width="fill_parent"        android:layout_height="fill_parent" >        <com.byl.testbaidumap.MyLocationMapView            android:id="@+id/bmapView"            android:layout_width="fill_parent"            android:layout_height="fill_parent"            android:clickable="true" />        <RelativeLayout            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:layout_marginLeft="10dp"            android:layout_marginRight="10dp"            android:layout_marginTop="10dp"            android:background="@drawable/edit_bg_all" >            <EditText                android:id="@+id/txtAddr"                android:layout_width="fill_parent"                android:layout_height="40dp"                android:layout_centerVertical="true"                android:layout_marginRight="2dp"                android:layout_toLeftOf="@+id/btOk"                android:background="@drawable/edit_bg_all"                android:completionThreshold="2"                android:drawableLeft="@drawable/qz_icon_seabar_search"                android:hint="请输入搜索关键字" />            <TextView                android:id="@+id/btOk"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_centerVertical="true"                android:layout_marginRight="2dp"                android:layout_toLeftOf="@+id/s2"                android:text="搜索"                android:textSize="18sp" />            <ImageView                android:id="@+id/s2"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_centerVertical="true"                android:layout_marginRight="2dp"                android:layout_toLeftOf="@+id/btget"                android:src="@drawable/slide_center" />            <TextView                android:id="@+id/btget"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_alignParentRight="true"                android:layout_centerVertical="true"                android:text="定位"                android:textSize="18sp" />        </RelativeLayout>    </FrameLayout></RelativeLayout>

注意，密钥是在aplication中声明的：

package com.byl.testbaidumap;import android.app.Application;import android.content.Context;import android.widget.Toast;import com.baidu.mapapi.BMapManager;import com.baidu.mapapi.MKGeneralListener;import com.baidu.mapapi.map.MKEvent;public class MyApplication extends Application {    private static MyApplication mInstance = null;    public boolean m_bKeyRight = true;    public BMapManager mBMapManager = null;    public static final String strKey = "58byjGtcTxxOBRBCYBGCj8dt";@Override    public void onCreate() {    super.onCreate();mInstance = this;initEngineManager(this);}public void initEngineManager(Context context) {        if (mBMapManager == null) {            mBMapManager = new BMapManager(context);        }        if (!mBMapManager.init(strKey,new MyGeneralListener())) {            Toast.makeText(MyApplication.getInstance().getApplicationContext(), "BMapManager  初始化错误!", Toast.LENGTH_LONG).show();        }}public static MyApplication getInstance() {return mInstance;}// 常用事件监听，用来处理通常的网络错误，授权验证错误等    public static class MyGeneralListener implements MKGeneralListener {                @Override        public void onGetNetworkState(int iError) {            if (iError == MKEvent.ERROR_NETWORK_CONNECT) {                //Toast.makeText(DemoApplication.getInstance().getApplicationContext(), "您的网络出错啦！",Toast.LENGTH_LONG).show();            }            else if (iError == MKEvent.ERROR_NETWORK_DATA) {                Toast.makeText(MyApplication.getInstance().getApplicationContext(), "输入正确的检索条件！",Toast.LENGTH_LONG).show();            }            // ...        }        @Override        public void onGetPermissionState(int iError) {        //非零值表示key验证未通过            if (iError != 0) {                //授权Key错误：//                Toast.makeText(DemoApplication.getInstance().getApplicationContext(), //                        "请在 DemoApplication.java文件输入正确的授权Key,并检查您的网络连接是否正常！error: "+iError, Toast.LENGTH_LONG).show();//                DemoApplication.getInstance().m_bKeyRight = false;                MyApplication.getInstance().m_bKeyRight = true;            }            else{            MyApplication.getInstance().m_bKeyRight = true;            //Toast.makeText(DemoApplication.getInstance().getApplicationContext(), "key认证成功", Toast.LENGTH_LONG).show();            }        }    }}

当然，不要忘了在清单文件中配置aplication：

<application        android:name="com.byl.testbaidumap.MyApplication"

还有调用百度地图相关的权限都已在清单文件中写的很清楚，以及代码中注释也比较详细，大家可以下载我的源码作为参考：
