Android 之WebView
WebView类有2个方法装载HTML代码
1-publicvoidloadData(Stringdata,StringmimeType,Stringencoding);
2-publicvoidloadDataWithBaseURL(StringbaseURL,Stringdata,StringmimeType,
Stringencoding,StringfailUrl);
其中LoadData参数含义如下：(包含中文的HTML代码会出现乱码)
data:HTML代码
mimeType:Mime类型一般为text/html
encoding:HTML代码的编码
loadDataWidthBaseURL方法的参数含义如下：（建议使用该方法装载HTML代码）
baseUrl:获取相对路径的根URL如果设为null默认值是about:blank
failUrl:如果HTML代码装载失败或为Null时，WebView控件会装载这个参数指定的URL
打开JavaScript功能
webView.getSettings().setJavaScriptEnabled(true);
设置处理JavaScript的引擎
webView.setWebChromeClient(newWebChromeClient);
public class Main extends Activity
{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WebView webView = (WebView) findViewById(R.id.webview);
String html = "<html>"
+ "<body>"
+ "图书封面<br>"
+ "<table width='200' border='1' >"
+ "<tr>"
+ "<td><a onclick='alert(\"Java Web开发速学宝典\")' ><img style='margin:10px' src='http://images.china-pub.com/ebook45001-50000/48015/cover.jpg' width='100'/></a></td>"
+ "<td><a onclick='alert(\"大象--Thinking in UML\")' ><img style='margin:10px' src='http://images.china-pub.com/ebook125001-130000/129881/zcover.jpg' width='100'/></td>"
+ "</tr>"
+ "<tr>"
+ "<td><img style='margin:10px' src='http://images.china-pub.com/ebook25001-30000/27518/zcover.jpg' width='100'/></td>"

+ "</tr>" + "</table>" + "</body>" + "</html>";
webView.loadDataWithBaseURL("图书名", html, "text/html", "utf-8", null);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient());
