KS系列之百度地圖基本功能的實現（二）

之前只是簡單集成百度地圖，但是並沒有實現我們平時想要的功能。
譬如點擊獲取定位，切換路況交通圖，衛星圖，對地圖的縮放等

佈局

   <RelativeLayout
        android:id="@+id/fl_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

            android:padding="@dimen/padding_10"
            android:src="@drawable/ic_map_my_location" />

    </RelativeLayout>

獲取定位

   isFirstLoc = true;
// 開啓定位圖層
//mBaiduMap.setMyLocationEnabled(true);
//// 定位初始化
mLocClient = new LocationClient(this);
mLocClient.registerLocationListener(myListener);
LocationClientOption option = new LocationClientOption();
option.setOpenGps(true); // 打開gps
option.setCoorType("bd09ll"); // 設置座標類型
option.setScanSpan(1000);
mLocClient.setLocOption(option);
mLocClient.start();

定位監聽函數

   /**
 * 定位SDK監聽函數
 */
public class MyLocationListenner implements BDLocationListener {

@Override
public void onReceiveLocation(BDLocation location) {
// map view 銷燬後不在處理新接收的位置
if (location == null || bdMapView == null) {
return;
}
mCurrentLat = location.getLatitude();
mCurrentLon = location.getLongitude();
mCurrentAccracy = location.getRadius();
locData = new MyLocationData.Builder()
.accuracy(300)
//.accuracy(location.getRadius())
// 此處設置開發者獲取到的方向信息，順時針0-360
.direction(mCurrentDirection).latitude(location.getLatitude())
.longitude(location.getLongitude()).build();
mBaiduMap.setMyLocationData(locData);
if (isFirstLoc) {
isFirstLoc = false;
LatLng ll = new LatLng(location.getLatitude(),
location.getLongitude());
MapStatus.Builder builder = new MapStatus.Builder();
builder.target(ll).zoom(18.0f);
mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build()));
}
}

切換路況交通圖

   if (!isTrafficOpen) {
showToast("實時路況打開");
mBaiduMap.setTrafficEnabled(true);
ivTraffic.setImageResource(R.drawable.ic_map_traffic_open);
isTrafficOpen = !isTrafficOpen;
} else {
showToast("實時路況關閉");
mBaiduMap.setTrafficEnabled(false);
ivTraffic.setImageResource(R.drawable.ic_map_traffic_close);
isTrafficOpen = !isTrafficOpen;
}

切換衛星圖

if (!isViewcSwitch) {
                showToast("切換衛星視圖");
                mBaiduMap.setMapType(BaiduMap.MAP_TYPE_SATELLITE);
                isViewcSwitch = !isViewcSwitch;
            } else {
                showToast("衛星視圖關閉");
                mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);
                isViewcSwitch = !isViewcSwitch;

            }

縮放

if (mCurrentZoomLevel < 7) {
                ivMinus.setEnabled(false);
                ivMinus.setImageResource(R.drawable.ic_map_minus_gray);
            } else {
                mBaiduMap.setMapStatus(MapStatusUpdateFactory.zoomOut());
                ivPlus.setEnabled(true);
                ivPlus.setImageResource(R.drawable.ic_map_plus);
                ivMinus.setEnabled(true);
                ivMinus.setImageResource(R.drawable.ic_map_minus);
            }

修改自定義marker

 // 修改爲自定義marker
    mCurrentMarker = BitmapDescriptorFactory
            .fromResource(R.drawable.ic_map_location);
    mBaiduMap.setMyLocationConfiguration(new MyLocationConfiguration(
            mCurrentMode, true, mCurrentMarker,
            getMyColor(R.color.mapColor), getMyColor(R.color.mapColor)));
