HTC Desire 的雙向錄音功能的點殘缺

用一陣子，才想到要錄音的功能，所以在Market 找了兩三套來試，都有想同的問題，就是另一方通話的聲音太小了，在想不會那麼巧吧!，所以在網站爬了一下。原來問題在 Android 不知道Google 什麼會改善。

AS3 Singleton Pattern

為了確保類別的實體化不會有第二次，不論系統內何處實體化都是相同的物件，可以用來當做全域變數的實體物件

SingletonTest.as

package
{
import flash.display.Sprite;
public class SingletonTest extends Sprite
{
public function SingletonTest()
{
var initialSingleton:Singleton = Singleton.getInstance();
var subsequentSingleton:Singleton = Singleton.getInstance();
}
}
}

Singleton.as

package
{
public class Singleton
{
private static var _instance:Singleton;
public function Singleton(pvt:PrivateClass) {
}
public static function getInstance():Singleton
{
if(Singleton._instance == null)
{
Singleton._instance=new Singleton(new PrivateClass());
trace("Singleton instantiated");
}
else
{
trace("Sorry--already have a Singleton instantiated")
}
return Singleton._instance;
}
}
}

class PrivateClass
{
public function PrivateClass() {
trace("Private class is up");
}
}

建立文字盒 TextField

import flash.text.*;

var label1:TextField ;

label1 = createCustomTextField(100, 500, 400, 20);
label1.text = "Webco.TW";

private function createCustomTextField(x:Number, y:Number, width:Number, height:Number):TextField {

var result:TextField = new TextField();
   result.x = x; result.y = y;
   result.width = width; result.height = height;
   addChild(result);

var my_fmt:TextFormat = new TextFormat();
my_fmt.color = 0xFFFFFF;
result.defaultTextFormat = my_fmt;

   return result;
}

建議從國小課程之各階段開始，如此可復習並增加耳語聽力習慣！
點選進入國小課程，並從初級選項開始！
進入初級選項後，點選藍色顯示項目「馬上練習」。每日選擇一項即可，把該項之三十個單字(每一項目量皆同)嚐試過後即可休息，很輕鬆吧^^，如此日日練習即可見功效。
練習時，請跟著外籍女士所錄製的純正語音發音，念出來之後，再選擇該單字的正確意思。如此，可加強印象並校正口語腔調。養成習慣，出國不亂！^^
