JQuery Mobile入门——多种类型的网格布局

1、JQuery Mobile 提供的CSS样式ui-grid可以实现内容的网格布局，该样式有4种预设的配置布局：ui-grid-a、ui-grid-b、ui-grid-c、ui-grid-d，分别对应为两列、三列、四列、五列的网格布局形式。使用网格布局时，整个宽度为100%，无任何padding，margin及背景颜色，因此不会影响到其他元素放入网格中的位置。

2、示例代码：

<HTML>
 <HEAD>
  <TITLE> New Document </TITLE>
  <meta name="viewport" content="width=device-width,initial-scale=1"/>
  <link href="/blog_article/Css/jquery.mobile-1.2.0.min.css" rel="Stylesheet" type="text/css"/>
  <script src="/blog_article/Js/jquery-1.8.3.min.js" type"text/javascript"></script>
  <script src="/blog_article/Js/jquery.mobile-1.2.0.min.js" type="text/javascript"></script>
 </HEAD>
 <BODY>
    <div data-role="page">
 <div data-role="header"><h1>头部栏标题</h1></div>
 <div >
   <div >
 <div >A</div>

[2] Notification中Intent携带数据重复有关问题
    来源: 互联网  发布时间: 2014-02-18
Notification中Intent携带数据重复问题

Notification中多个Intent使用putExtra方法携带数据，在目的activity中通过getIntent方法取出传递数据时，有时候会发现取出来的数据都是第一次putExtra中放入的数据。

下面看下代码，比较简单：

package com.example.notificationdemo;

import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;


public class FirstActivity extends Activity {
	
	private Button mButton;
	
	private NotificationManager mNotificationManager;
	private Intent mIntent;
	private PendingIntent mPendingIntent;
	Notification mNotification;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.first);	
		
		mNotification = new Notification();
		mIntent = new Intent(FirstActivity.this, MainActivity.class);
		mIntent.putExtra("hello", "first");
		Log.v("@@@@@@", "this is put in intent first....");
		mNotificationManager = 
				(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
		//主要在于PendingIntent的getActivity方法中的参数
		mPendingIntent = PendingIntent.getActivity(FirstActivity.this, 0, mIntent, PendingIntent.FLAG_UPDATE_CURRENT);
		//如果使用下面注释掉的代码，将会出现上面说讲到的问题,当然在SecondActivity中也必须做修改
		//mPendingIntent = PendingIntent.getActivity(FirstActivity.this, 0, mIntent, 0);
		mButton = (Button)findViewById(R.id.first_button);
		mButton.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View view) {
				showNotification();
			}
		});
	}
	
	private void showNotification() {  
		
		mNotification.icon = R.drawable.message;
		mNotification.defaults = Notification.DEFAULT_SOUND; 
		mNotification.flags |= Notification.FLAG_AUTO_CANCEL;
		mNotification.tickerText = "第一个";
		mNotification.setLatestEventInfo(FirstActivity.this, "第一个",
				"第一个", mPendingIntent);
		mNotificationManager.notify(0, mNotification);
	}
}

第二个Activity：

package com.example.notificationdemo;

import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class SecondActivity extends Activity {
	
	private Button mButton;	
	private NotificationManager mNotificationManager2;
	private Intent mIntent;
	private PendingIntent mPendingIntent2;
	Notification mNotification2;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.second);
		
		mNotification2 = new Notification();
		mIntent = new Intent(SecondActivity.this, MainActivity.class);
		mIntent.putExtra("hello", "second");
		Log.v("@@@@@@", "this is doing in second activity");
		mNotificationManager2 = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
		mPendingIntent2 = PendingIntent.getActivity(SecondActivity.this, 1, mIntent, PendingIntent.FLAG_UPDATE_CURRENT);
		//如果使用下面注释掉的代码，将会出现上面说讲到的问题,当然在FirstActivity中也必须做修改（把上面代码注释掉，使用下面行代码，就会重现）
		//mPendingIntent2 = PendingIntent.getActivity(SecondActivity.this, 0, mIntent, 0);
		
		mButton = (Button) findViewById(R.id.second_button);		
		mButton.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View view) {
				showNotification();
			}
		});	
	}
	
	private void showNotification() {    			
		
		mNotification2.icon = R.drawable.message2;
		mNotification2.defaults = Notification.DEFAULT_SOUND; 
		mNotification2.flags |= Notification.FLAG_AUTO_CANCEL;
		mNotification2.tickerText = "第二个";
		
		Log.v("@@@@@@", "intent put second ...");
		mNotification2.setLatestEventInfo(SecondActivity.this, "第二个", "第二个", mPendingIntent2);
		Log.v("@@@@@@", "do shownotification in second activity");
		mNotificationManager2.notify(0, mNotification2);
		
	}	
}

在MainActivity中接受两个Activity中的Notification传过来的数据：

package com.example.notificationdemo;

import android.os.Bundle;
import android.app.TabActivity;
import android.content.Intent;
import android.graphics.Color;
import android.util.Log;
import android.view.Menu;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.RadioGroup.OnCheckedChangeListener;
import android.widget.TabHost;

public class MainActivity extends TabActivity implements OnCheckedChangeListener{

	private TabHost mTabHost;
	private RadioGroup mRadioGroup;
	private RadioButton mFirstRadio, mSecondRadio;
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        mTabHost = getTabHost();
		mTabHost.addTab(mTabHost.newTabSpec("first").setIndicator("First").setContent(new Intent(this, FirstActivity.class)));
		mTabHost.addTab(mTabHost.newTabSpec("second").setIndicator("Second").setContent(new Intent(this, SecondActivity.class)));
        
        mRadioGroup = (RadioGroup) findViewById(R.id.radiogroup);
		mRadioGroup.setOnCheckedChangeListener(this);
		mFirstRadio = (RadioButton)findViewById(R.id.first_radio);
		mSecondRadio = (RadioButton) findViewById(R.id.second_radio);
		
		Log.v("@@@@@@", "this is doing  in onCreate");
        ChangeChecked(true);
        String str = getIntent().getStringExtra("hello");
    	Log.v("@@@@@@", "the str is " + str);
    	if (str != null && str.equals("first")) {
    		ChangeChecked(true);
    		mTabHost.setCurrentTabByTag("first");
    	} else if (str != null && str.equals("second")) {
    		ChangeChecked(false);
    		mTabHost.setCurrentTabByTag("second");
    	}
        
    }
    
    @Override
    protected void onNewIntent(Intent intent) {    	
    	String str = intent.getStringExtra("hello");
    	if (str != null && str.equals("first")) {
    		ChangeChecked(true);
    		mTabHost.setCurrentTabByTag("first");
    	} else if (str != null && str.equals("second")) {
    		ChangeChecked(false);
    		mTabHost.setCurrentTabByTag("second");
    	}
    	super.onNewIntent(intent);
    	
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

	@Override
	public void onCheckedChanged(RadioGroup group, int checkedId) {
		switch (checkedId) {
		case R.id.first_radio:
			mTabHost.setCurrentTabByTag("first");
			ChangeChecked(true);
			break;
		case R.id.second_radio:
			mTabHost.setCurrentTabByTag("second");
			ChangeChecked(false);
			break;
		default :
			break;
		}
		
	}
	
	private void ChangeChecked(boolean bool) {
		if (bool) {
			mFirstRadio.setTextColor(Color.RED);
			mFirstRadio.setBackgroundResource(R.drawable.tab_front_bg);
			mSecondRadio.setTextColor(Color.BLACK);
			mSecondRadio.setBackgroundColor(Color.TRANSPARENT);
		} else {
			mSecondRadio.setTextColor(Color.RED);
			mSecondRadio.setBackgroundResource(R.drawable.tab_front_bg);
			mFirstRadio.setTextColor(Color.BLACK);
			mFirstRadio.setBackgroundColor(Color.TRANSPARENT);
		}
	}
}

问题主要出自：

mPendingIntent2 = PendingIntent.getActivity(SecondActivity.this, 1, mIntent, PendingIntent.FLAG_UPDATE_CURRENT);
		//如果使用下面注释掉的代码，将会出现上面说讲到的问题,当然在FirstActivity中也必须做修改（把上面代码注释掉，使用下面行代码，就会重现）
		//mPendingIntent2 = PendingIntent.getActivity(SecondActivity.this, 0, mIntent, 0);

看一下getActivity方法：

 PendingIntent android.app.PendingIntent.getActivity(Context context, int requestCode, Intent intent, int flags)


Retrieve a PendingIntent that will start a new activity, like calling Context.startActivity(Intent). Note that the activity will be started outside of the context of an existing activity, so you must use the Intent.FLAG_ACTIVITY_NEW_TASK launch flag in the Intent.

Parameters:
context The Context in which this PendingIntent should start the activity.
requestCode Private request code for the sender (currently not used).
intent Intent of the activity to be launched.
flags May be FLAG_ONE_SHOT, FLAG_NO_CREATE, FLAG_CANCEL_CURRENT, FLAG_UPDATE_CURRENT, or any of the flags as supported by Intent.fillIn() to control which unspecified parts of the intent that can be supplied when the actual send happens.
Returns:
Returns an existing or new PendingIntent matching the given parameters. May return null only if FLAG_NO_CREATE has been supplied.


参数requestCode用于区分Intent，如果flag为FLAG_UPDATE_CURRENT会即使更新intent中数据。

关于该方法的详细概述，敬请查看后面关于notification的源码解析，打算在周末的时候看一下notification源码，那个时候再详细分析下。



    
[3] unity StreamingAssets途径
    来源: 互联网  发布时间: 2014-02-18
unity StreamingAssets路径

  我们在读写例如XML和TXT文件的时候，在电脑上和手机上路径不一致，造成了很多麻烦，其实有个简单的方法，在项目工程中新建一个StreamingAssets文件夹，把你的XML和TXT文件放到这里。

using UnityEngine; 
using System.Collections; 
using System.Xml; 
using System.Xml.Serialization; 
using System.IO; 
using System.Text; 
 
public class Reward  
 { 
   public int taskNo;
   
   public Task[] task = new Task[15];
   public Attribute attribute; 
   public Reward () {} 
   public struct Task
   { 
	  [XmlAttribute("taskReward")] 
	  public string taskReward{ get; set;} 
	  public Id id1; 
	  public Id id2;
      public Id id3;
   }
   public struct Id
   {
	  [XmlAttribute("flag")] 
	  public bool flag{ get; set;} 
	  [XmlAttribute("name")] 
	  public string name{ get; set;}
	  [XmlText()]
	  public string description{get;set;}
		
   }  
}

public class AchievementManager: MonoBehaviour { 
   Reward reward ; 
   FileInfo fileInfo;
   string _data; 
	
   void Start () 
   {   
      reward = new Reward();
	  LoadXML();
   } 
   void LoadXML() 
   { 
	  if(Application.platform == RuntimePlatform.IPhonePlayer)
	  {
		 fileInfo = new FileInfo(Application.dataPath + "/Raw/" + "Achievement.xml"); 
		  StreamReader r = fileInfo.OpenText(); 
         _data = r.ReadToEnd(); 
         r.Close(); 
	  }
	  else if(Application.platform == RuntimePlatform.Android)
	  {
		 fileInfo = new FileInfo(Application.streamingAssetsPath+"/Achievement.xml");
	     StartCoroutine("LoadWWW");
	  }
	  else
	  {
		 fileInfo = new FileInfo(Application.dataPath + "/StreamingAssets/"+ "Achievement.xml"); 
		 StreamReader r = fileInfo.OpenText(); 
         _data = r.ReadToEnd(); 
         r.Close(); 
      }	  
	  if(_data.ToString() != "") 
      { 
         reward = (Reward)DeserializeObject(_data);              
      } 
   }
   void OnGUI()
   {
	   GUI.Label(new Rect(0,0,Screen.width,Screen.height),"data:"+_data);	 
	   if(Input.GetKey(KeyCode.Space))
		{
			Application.Quit(); 
		}
   }
	
	IEnumerator LoadWWW()
	{
		WWW www = new WWW(Application.streamingAssetsPath+"/Achievement.xml");
		yield return www;
		_data =www.text;
	}
   public void Save()
   {     
      _data = SerializeObject(reward);
	  StreamWriter writer; 
      fileInfo.Delete();    
	  writer = fileInfo.CreateText(); 
      writer.Write(_data);
      writer.Close(); 
   }
   string UTF8ByteArrayToString(byte[] characters) 
   {      
      UTF8Encoding encoding = new UTF8Encoding(); 
      string constructedString = encoding.GetString(characters); 
      return (constructedString); 
   } 
 
   byte[] StringToUTF8ByteArray(string pXmlString) 
   { 
      UTF8Encoding encoding = new UTF8Encoding(); 
      byte[] byteArray = encoding.GetBytes(pXmlString); 
      return byteArray; 
   } 
 
   // Here we serialize our Reward object of reward 
   string SerializeObject(object pObject) 
   {
	  string XmlizedString = null; 
      MemoryStream memoryStream = new MemoryStream(); 
      XmlSerializer xs = new XmlSerializer(typeof(Reward)); 
      XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8); 
      xs.Serialize(xmlTextWriter, pObject); 
      memoryStream = (MemoryStream)xmlTextWriter.BaseStream; 
      XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray()); 
      return XmlizedString; 
   } 
 
   // Here we deserialize it back into its original form 
   object DeserializeObject(string pXmlizedString) 
   { 
      XmlSerializer xs = new XmlSerializer(typeof(Reward)); 
      MemoryStream memoryStream = new MemoryStream(StringToUTF8ByteArray(pXmlizedString)); 
      XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8); 
      return xs.Deserialize(memoryStream); 
   } 
}


注：其实每个平台的路径都可以是Application.streamingAssetsPath+"/Achievement.xml"。但是android平台必须要用WWW加载，其他的平台貌似也可以的，自己试试哈，呵呵~~~
