[Android]百度地图之地图标注

上一篇博文我们探讨了百度地图的SDK的环境集成与搭建，这篇文章将介绍如何在百度地图上进行标注。

1、在activity_main.xml中新建bmapView

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
    <!-- 添加百度地图控件 -->
    <com.baidu.mapapi.map.MapView
    android:id="@+id/bmapView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:clickable="true" />
</LinearLayout>

2、在MainActivity.java中获取mapView并进行标注。

package com.example.baidu_demo_2;

import com.baidu.mapapi.BMapManager;
import com.baidu.mapapi.SDKInitializer;
import com.baidu.mapapi.map.BaiduMap;
import com.baidu.mapapi.map.BitmapDescriptor;
import com.baidu.mapapi.map.BitmapDescriptorFactory;
import com.baidu.mapapi.map.MapView;
import com.baidu.mapapi.map.MarkerOptions;
import com.baidu.mapapi.map.OverlayOptions;
import com.baidu.mapapi.model.LatLng;

import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.os.Build;

public class MainActivity extends ActionBarActivity {
    private MapView mapView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        SDKInitializer.initialize(getApplicationContext());
        setContentView(R.layout.activity_main);
        mapView = (MapView)this.findViewById(R.id.bmapView);

        // 设置地图类型
        BaiduMap mBaiduMap  = mapView.getMap();

        // 普通地图
        mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);

        // 卫星地图
//        mBaiduMap.setMapType(BaiduMap.MAP_TYPE_SATELLITE);

        //实时交通地图
//        mBaiduMap.setTrafficEnabled(true);

        // 地图标注
        LatLng point = new LatLng(39.963175, 116.400244);
        BitmapDescriptor bitmapDescriptor = BitmapDescriptorFactory.fromResource(R.drawable.icon_marka);
        OverlayOptions overlayOptions = new MarkerOptions().position(point).icon(bitmapDescriptor);
        mBaiduMap.addOverlay(overlayOptions);
    }
}
