GoogleMap-------manifest文件配置

前言：在使用GoopleMap之前需要配置manifest文件　　

  1.这个可有可无，com.xhm.meishi是项目的包名

    <!-- 声明调用这个应用需要的权限 -->
    <permission
        android:name="com.xhm.meishi.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

permission的意义可参考如下文章：http://blog.csdn.net/aomandeshangxiao/article/details/6940941撒地方
2.申请权限和GLE

<!-- 申请权限 -->
    <uses-permission android:name="com.xhm.meishi.permission.MAPS_RECEIVE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <!-- 申请glE特性 -->
    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

3.配置API_KEY

<meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyAB8aPMVDw036l87RutL6jkwDeEgLrQEaY" />

4.XML布局

<fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

这里建议使用SupportMapFragment，而不MapFragment
5.Activity文件，在布局中使用SupportMapFragment时，这个文件要继承FragmentActivity，而不是Activity

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.page_layout);
    }

　全部代码如下：

　　Manifest：

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

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />
    <!-- 声明调用这个应用需要的权限 -->
    <permission
        android:name="com.xhm.meishi.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />
    <!-- 申请权限 -->
    <uses-permission android:name="com.xhm.meishi.permission.MAPS_RECEIVE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <!-- 申请glE特性 -->
    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.xhm.meishi.Page_Activity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyAB8aPMVDw036l87RutL6jkwDeEgLrQEaY" />
    </application>

</manifest>

　　xml布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".Page_Activity" >

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

　　activity文件

package com.xhm.meishi;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;

public class Page_Activity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.page_layout);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.page_, menu);
        return true;
    }

}
