phoneGap平台的运用
phoneGap是一款让你轻松实现web与Android应用的结合一个开发平台，使用JS+HTML5,直接运行web app.
下面我就给出一个小例子实现Google地图。
首先要下载jar包：
http://www.phonegapcn.com/
然后将phonegap.jar和phonegap.js包导入Android工程中即可，如图所示：
下一步就是加入权限：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.hello"
android:versionCode="1"
android:versionName="1.0" >
<supports-screens
android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:resizeable="true"
android:anyDensity="true"
/>
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:configChanges="orientation|keyboardHidden"
android:name="com.example.hello.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.hello.DroidGap"
android:label="@string/app_name"
android:configChanges="orientation|keyboardHidden"
>
<intent-filter>
</intent-filter>
</activity>
</application>
</manifest>
看看主窗口：
package com.example.hello;
import android.os.Bundle;
import android.view.Menu;
import com.phonegap.DroidGap;
public class MainActivity extends DroidGap {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.loadUrl("file:///android_asset/www/index.html");
}
}
将setContentView 换成super.loadUrl，index文件存放在assets目录下，然后我们来看看HTML+JS的魅力吧：
index.html
<html>
<head>
<title>Map鐨勬樉绀哄拰瀹氫綅</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<style>
html, body, #map_canvas {
margin: 0;
padding: 0;
height: 100%;
}
</style>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script>
function initialize() {
var mapOptions = {
zoom: 15,
// 瀹氫綅鍒版矆闃崇櫨鑴戞眹
center : new google.maps.LatLng(41.764998, 123.427109),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
new google.maps.Map(document.getElementById('map_canvas'),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map_canvas"></div>
</body>
</html>
最后记得在AndroidManifest.xml注册，代码已经贴上了，最后我们来看看运行结果：
