一、背景
1、最近在做一個android端播放flash的應用，android裝置沒有螢幕，顯示需通過HDMI串連。需要用到javascript與java之間的互動，android端接收flash傳過來的fscommand
2、希望通過WebView載入html實現
二、遇到問題
1、通過html載入之後的動畫，無論按哪個按鍵，swf檔案都接收不到按鍵訊息，既不能實現它本身的一些操作性功能
2、傳過來的命令接收不到（有時間再分析這個，已經解決）
三、嘗試方法
1、發現如果直接通過電腦端使用瀏覽器開啟該html，直接敲鍵盤也是沒有效果的，可滑鼠點擊一下，按鍵卻有效果了
2、沒有收到命令，通過添加flash安全沙箱路徑即可，當然，你得安裝flash player
3、通過猜測覺得應該是WebView開始的時候沒有擷取到焦點，所以按鍵事件一直沒有捕捉
四、成功解決
1、html載入main.swf
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" "http://www.wapforum.org/DTD/xhtml-mobile10.dtd "><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><script language="JavaScript" type="text/JavaScript">var str1 = "hello";var InternetExplorer = navigator.appName.indexOf("Microsoft") != -1;function myFlash_DoFSCommand(command, args) { var myFlashObj = InternetExplorer ? myFlash : document.myFlash; if(command == "back"){//alert(command);doFromCommand(command); }else{alert(command); }}if (navigator.appName && navigator.appName.indexOf("Microsoft") != -1 && navigator.userAgent.indexOf("Windows") != -1 && navigator.userAgent.indexOf("Windows 3.1") == -1) { document.write('<SCRIPT LANGUAGE=VBScript\> \n'); document.write('on error resume next \n'); document.write('Sub myFlash_FSCommand(ByVal command, ByVal args)\n'); document.write(' call myFlash_DoFSCommand(command, args)\n'); document.write('end sub\n'); document.write('</SCRIPT\> \n');} function doFromCommand(command){ window.myjs2.runJs2Activity(command);//調用android的函數 }</script></head> <body><OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=11,0,0,0" WIDTH="100%" HEIGHT="100%" id="myFlash"> <PARAM NAME=movie VALUE="main.swf"> <PARAM NAME=quality VALUE=high> <PARAM NAME=bgcolor VALUE=#CCCCCC> <param name="allowScriptAccess" value="always" /> <param name="allowNetworking" value="all"> <param name="allowFullScreen" value="true"> <EMBED src="main.swf" quality=high bgcolor=#CCCCCC WIDTH="100%" HEIGHT="100%" NAME="myFlash" swLiveConnect="true" allowScriptAccess="always" allownetworking="all" TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/go/getflashplayer"></EMBED></OBJECT> <div id="show" style="color:#000000;font-size:30px;margin-left:50px" ></div></body></html>
WIDTH="100%" HEIGHT="100%"這個是根據裝置撐滿螢幕，針對在不同解析度不同螢幕大小的裝置來說，該屬性是必不可少的
2、類比點擊事件，可在html載入成功之後加入下面代碼
mWebView.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(),MotionEvent.ACTION_DOWN, mWebView.getLeft() + 5,mWebView.getTop() + 5, 0));mWebView.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(),MotionEvent.ACTION_UP, mWebView.getLeft() + 5,mWebView.getTop() + 5, 0));
