編寫簡單的百度地图(Baidu Map)應用程序

完成前文的準備工作, 現在我們可以動手編寫百度地图應用程序.

- 修改 main.xml, 加入 com.baidu.mapapi.MapView, 這是百度地图的視圖.

<?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" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />
    <com.baidu.mapapi.MapView 
        android:id="@+id/bmapsView"
  android:layout_width="fill_parent" 
  android:layout_height="fill_parent"
  android:clickable="true" />

</LinearLayout>

- 修改活動的主要 Java 代碼, 注意它是擴展 MapActivity, 不是 Activity. MY_KEY字串須使用你自己的密鑰, 參考前文"準備工作".

package com.BaiduMap;

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

import android.os.Bundle;

public class BaiduMapActivity extends MapActivity {
 
 //使用你自己的密鑰
 //參考準備工作 http://goo.gl/j6HkK
 final static String MY_KEY = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
 
 BMapManager mBMapMan;
 
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        mBMapMan = new BMapManager(getApplication());
        mBMapMan.init(MY_KEY, null);
        super.initMapActivity(mBMapMan);
         
        MapView mMapView = (MapView) findViewById(R.id.bmapsView);
        mMapView.setBuiltInZoomControls(true);
         
        MapController mMapController = mMapView.getController();
        GeoPoint point = new GeoPoint((int) (39.915 * 1E6),
                (int) (116.404 * 1E6));
        mMapController.setCenter(point);
        mMapController.setZoom(12);
    }

 @Override
 protected boolean isRouteDisplayed() {
  // TODO Auto-generated method stub
  return false;
 }

 @Override
 protected void onDestroy() {
  if (mBMapMan != null) {
         mBMapMan.destroy();
         mBMapMan = null;
     }
  super.onDestroy();
 }

 @Override
 protected void onPause() {
  if (mBMapMan != null) {
         mBMapMan.stop();
     }
  super.onPause();
 }

 @Override
 protected void onResume() {
  if (mBMapMan != null) {
         mBMapMan.start();
     }
  super.onResume();
 }
 
}
