百度地图Android SDK v2.0.0的简单使用

百度官方的开发指南：http://developer.baidu.com/map/sdkandev-2.htm

今天搞了一下午，总报错error inflating class com.baidu.mapapi.map.MapView

后来翻看开发指南才解决了问题：要在setContentView前初始化BMapManager对象，否则会报错

貌似刚好碰上开发指南的更新。。几个钟就这样没了。。

而且今天申请的key貌似也用不了。。用以前的就可以。。还有就是我的key列表上所有的key都没了。。

浪费了我这么多时间。。

简单的demo：

package my.daokantushuo;

import com.baidu.mapapi.BMapManager;
import com.baidu.mapapi.MKGeneralListener;
import com.baidu.mapapi.map.MKEvent;
import com.baidu.mapapi.map.MapController;
import com.baidu.mapapi.map.MapView;
import com.baidu.platform.comapi.basestruct.GeoPoint;

import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.view.Menu;
import android.view.Window;
import android.widget.Toast;

public class MyMapActivity extends Activity {
    private BMapManager mBMapMan=null;
    private MapView mMapView=null;
    private static final String BMAPKEY = "你的key";
    private static Context mapContext;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //去掉标题
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        
        mBMapMan = new BMapManager(getApplication());
        mBMapMan.init(BMAPKEY, new MyGeneralListener());
        
        //注意：请在用使用setContentView前初始化BMapManager对象，否则会报错
        setContentView(R.layout.activity_my_map);
        
        mapContext = getApplicationContext();
        mMapView = (MapView) findViewById(R.id.bmapsView);
        mMapView.setBuiltInZoomControls(true); //设置启用内置的缩放控件
         
        MapController mMapController = mMapView.getController(); // 得到mMapView的控制权,可以用它控制和驱动平移和缩放
        GeoPoint point = new GeoPoint((int) (39.915 * 1E6), (int) (116.404 * 1E6)); //用给定的经纬度构造一个GeoPoint，单位是微度 (度 * 1E6)
        mMapController.setCenter(point); //设置地图中心点
        mMapController.setZoom(12); //设置地图zoom级别
        //双击地图放大
        mMapView.setDoubleClickZooming(true);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_my_map, menu);
        return true;
    }
    
    @Override
    protected void onDestroy() {
        mMapView.destroy();
        if (mBMapMan != null) {
            mBMapMan.destroy();
            mBMapMan = null;
        }
        super.onDestroy();
    }
    
    @Override
    protected void onPause() {
        mMapView.onPause();
        if (mBMapMan != null) {
            mBMapMan.stop();
        }
        super.onPause();
    }
    
    @Override
    protected void onResume() {
        mMapView.onResume();
        if (mBMapMan != null) {
            mBMapMan.start();
        }
        super.onResume();
    }
    
    // 常用事件监听，用来处理通常的网络错误，授权验证错误等
    static class MyGeneralListener implements MKGeneralListener {
        
        @Override
        public void onGetNetworkState(int iError) {
            if (iError == MKEvent.ERROR_NETWORK_CONNECT) {
                Toast.makeText(mapContext, "您的网络出错啦！", Toast.LENGTH_LONG).show();
            }
            else if (iError == MKEvent.ERROR_NETWORK_DATA) {
                Toast.makeText(mapContext, "输入正确的检索条件！", Toast.LENGTH_LONG).show();
            }
            // ...
        }

        @Override
        public void onGetPermissionState(int iError) {
            if (iError ==  MKEvent.ERROR_PERMISSION_DENIED) {
                //授权Key错误：
                Toast.makeText(mapContext, "授权Key错误", Toast.LENGTH_LONG).show();
            }
        }
    }
}

布局文件activity_my_map.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">    
    <com.baidu.mapapi.map.MapView 
        android:id="@+id/bmapsView"
        android:layout_width="match_parent" 
        android:layout_height="match_parent"
        android:clickable="true" />
</LinearLayout>
