百度地圖__載入最簡單的地圖

Hello的例子

加入jar包

         

修改Manifest.xml

        根據百度lbs的那個Hello例子寫，增加網絡權限什麼的和開發的KEY。

增加到Main.xml       

   <!-- 只寫成MapView編譯通過 但運行肯定會出錯 找不到MapView -->
    <com.baidu.mapapi.map.MapView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/mapView" />
  

Activity.java中

public class MainActivity extends Activity {
    private MapView mapView;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		SDKInitializer.initialize(getApplicationContext());//必須寫在setContentView前
		setContentView(R.layout.activity_main);
		mapView=(MapView)findViewById(R.id.mapView);
	}
}

引入控制類BaiduMap

public class MainActivity extends Activity {
    private MapView mapView;
    private BaiduMap baiduMap;//引入控制器類
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		SDKInitializer.initialize(getApplicationContext());//必須寫在setContentView前
		setContentView(R.layout.activity_main);
		mapView=(MapView)findViewById(R.id.mapView);
		baiduMap=mapView.getMap();//獲取地圖的控制
		baiduMap.setMapType(BaiduMap.MAP_TYPE_SATELLITE);//setMapType設置爲衛星地圖
	}
}

增加覆蓋物OverlayOptions 

		baiduMap=mapView.getMap();//獲取地圖的控制
		LatLng point = new LatLng(39.963175, 116.400244); //插入位置 
		BitmapDescriptor bitmapDescripter=BitmapDescriptorFactory.fromResource(R.drawable.icon_gcoding);//圖標
		OverlayOptions imgOption=new MarkerOptions()//圖標Options=MarkerOptions 文字=TextOptions 幾何=PolygonOptions
		.position(point)
		.icon(bitmapDescripter);		
		baiduMap.addOverlay(imgOption);
		//圖標 文字 幾何都是用addOverlay(OverlayOptions option) 然後有按鈕彈出用showInfoWindow(InfoWindow infoWindow)

簡單--彈出框覆蓋物

 

        LatLng point=new LatLng(39.86923, 116.397428);     //1.LatLng 位置
		Button button=new Button(getApplicationContext()); //2.Button
		button.setBackgroundResource(R.drawable.popup);
		button.setText("click here");
		button.setTextColor(android.graphics.Color.BLACK);
		OnInfoWindowClickListener listener=new OnInfoWindowClickListener(){//3.OnInfoWindowClickListener監聽器
			@Override
			public void onInfoWindowClick() {
                Intent intent =new Intent(MainActivity.this,b.class);//跳轉到另一個頁面 記得mainfest.xml中多加個<Activity />
                MainActivity.this.startActivity(intent);
			}			
		};
		InfoWindow infoWindow=new InfoWindow(button,point,listener);//新建InfoWindow
		baiduMap.showInfoWindow(infoWindow);//顯示 這裏不用addOverlay了	

複雜點的--彈出覆蓋物
