百度地图3.1.0(二)基于MapFragment的基本地图

基于Fragment的百度Map也很简单

直接看例子吧：

AndroidManifest.xml的配置：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.testbaidu_v_3_1"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />

    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.USE_CREDENTIALS" />
    <uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />
    <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.BROADCAST_STICKY" />
    <uses-permission android:name="android.permission.WRITE_SETTINGS" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <meta-data
            android:name="com.baidu.lbsapi.API_KEY"
            android:value="your key" />
        
        <activity
            android:name=".MapFragment"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

MapFragment类：

package com.example.testbaidu_v_3_1;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.widget.Toast;

import com.baidu.mapapi.SDKInitializer;
import com.baidu.mapapi.map.BaiduMapOptions;
import com.baidu.mapapi.map.MapStatus;
import com.baidu.mapapi.map.SupportMapFragment;

public class MapFragment extends FragmentActivity{

    private SupportMapFragment map;
    private SDKReceiver mReceiver;
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        // 在使用SDK各组件之前初始化context信息，传入ApplicationContext
                // 注意该方法要再setContentView方法之前实现
                SDKInitializer.initialize(getApplicationContext());
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fragment);
        MapStatus ms = new MapStatus.Builder().overlook(-20).zoom(15).build();
        //overlook 设置地图俯仰角
        //zoom 设置地图缩放级别
        BaiduMapOptions bo = new BaiduMapOptions().mapStatus(ms)
                .compassEnabled(false).zoomControlsEnabled(false);
        //compassEnabled 设置是否允许指南针，默认允许
        //zoomControlsEnabled 设置是否显示缩放控件
        map = SupportMapFragment.newInstance(bo);
        FragmentManager manager = getSupportFragmentManager();
        manager.beginTransaction().add(R.id.map, map, "map_fragment").commit();
        
        IntentFilter iFilter = new IntentFilter();
        iFilter.addAction(SDKInitializer.SDK_BROADTCAST_ACTION_STRING_PERMISSION_CHECK_ERROR);
        iFilter.addAction(SDKInitializer.SDK_BROADCAST_ACTION_STRING_NETWORK_ERROR);
        mReceiver = new SDKReceiver();
        registerReceiver(mReceiver, iFilter);
    }

    protected void onDestroy() {
        super.onDestroy();
        // 在activity执行onDestroy时执行mMapView.onDestroy()，实现地图生命周期管理
        unregisterReceiver(mReceiver);
    }
    
    public class SDKReceiver extends BroadcastReceiver {
        public void onReceive(Context context, Intent intent) {
            String s = intent.getAction();
            if (s.equals(SDKInitializer.SDK_BROADTCAST_ACTION_STRING_PERMISSION_CHECK_ERROR)) {
                Toast.makeText(MapFragment.this,
                        "key 验证出错! 请在 AndroidManifest.xml 文件中检查 key 设置",
                        Toast.LENGTH_SHORT).show();
                ;
            } else if (s
                    .equals(SDKInitializer.SDK_BROADCAST_ACTION_STRING_NETWORK_ERROR)) {
                Toast.makeText(MapFragment.this, "网络出错", Toast.LENGTH_SHORT)
                        .show();
            }
        }
    }
}

activity_fragment.xml文件：

<?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" >

    <FrameLayout
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>
