百度地图的环境搭建(基于百度地图1.3.3)

1、AndroidManifest.xml

在AndroidManifest.xml中加上以下代码:

<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>

    <supports-screens
        android:anyDensity="true"
        android:largeScreens="true"
        android:normalScreens="true"
        android:resizeable="true"
        android:smallScreens="true" />

2、Main.xml

在里面加上以下代码:

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

3、在lib目录下导入相应的jar包(这个可以在官方文档中的标称里面找)

4、MainAcitivity

package com.njupt.bmap_helloworld;

import com.baidu.mapapi.BMapManager;
import com.baidu.mapapi.GeoPoint;
import com.baidu.mapapi.MKGeneralListener;
import com.baidu.mapapi.MapActivity;
import com.baidu.mapapi.MapController;
import com.baidu.mapapi.MapView;

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

public class MainActivity extends MapActivity {

	private MapView mapView;//百度地图的相关控件
	private BMapManager bMapManager;//加载地图的引擎
	private String keyString = "04763B1D8C925195965E838C6E59DB767DAE4BA7";//百度地图的key
	private MapController mapController;//在百度地图上添加一些控件,比如放大或缩小控件
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		
		mapView = (MapView) findViewById(R.id.bmapView);
		bMapManager = new BMapManager(MainActivity.this);
		
		//必须要加载key
		bMapManager.init(keyString, new MKGeneralListener() {
			
			@Override
			public void onGetPermissionState(int arg0) {
				if(arg0 == 300){
					Toast.makeText(MainActivity.this, "输入的key有误,请核实...", 1).show();
				}
			}
			
			@Override
			public void onGetNetworkState(int arg0) {
				// TODO Auto-generated method stub
				
			}
		});
		
		initMapActivity(bMapManager);
		mapView.setBuiltInZoomControls(true);//表示可以设置缩放功能.需要注意的是,这一句一定要放在initMapActivity之后才会起作用
		mapController = mapView.getController();
		GeoPoint geoPoint = new GeoPoint((int)(39.915*1E6), (int)(116.404*1E6));//定义经纬度
	    
		mapController.setCenter(geoPoint);//设置一个中心点
		mapController.setZoom(12);//设置缩放级别
	}

	@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 boolean isRouteDisplayed() {
		// TODO Auto-generated method stub
		return false;
	}
	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

}
