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"
android:completionThreshold="2"

<TextView

android:layout_width="wrap_content"

android:layout_centerVertical="true"
android:layout_marginRight="2dp"
android:layout_toLeftOf="@+id/s2"
android:text="搜索"
android:textSize="18sp" />
<ImageView

<TextView
android:id="@+id/btget"

android:layout_alignParentRight="true"

android:text="定位"

</RelativeLayout>
</FrameLayout>
</RelativeLayout>

注意，密钥是在aplication中声明的：

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：

}
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：
