在 上一篇博客中[url]http://serryzhao.iteye.com/blog/873896 [/url] 动态生成了个很丑的页面，怎么让人家客户看啊
为了UI漂亮些，于是今天写了半天用WebView来实现了。
buf = new StringBuffer();
buf.append("<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'>");
buf.append("<html xmlns='http://www.w3.org/1999/xhtml'>");
buf.append("<head><meta http-equiv='Content-Type' content='text/html; charset=utf-8' /><title>tab</title>" +
"<style type='text/css'>table.tab { border-collapse:collapse; border-spacing:0; width:100%; color:#000; font-size:18px;}" +
"table.tab input{width:200px; height:25px; font-size:16px;} table.tab th { text-align:right; padding:3px 0;}table.tab td { text-align:left; padding:3px 0;}</style></head>");
buf.append("<script language='javascript'> function send2Android(){ " +
" var car_type = ''; var car_ad = ''; var car_ads = ''; var engine_no = ''; var car_no = ''; var car_discern = ''; var record_no = ''; var driver_no = '';" +
" if(null!= document.getElementById('car_type')){ car_type = document.getElementById('car_type').value; }" +
" if(null != document.getElementById('car_ad')){ " +
" var temp = document.getElementById('car_ad'); " +
" car_ad = document.getElementById('car_ad').value;" +
" car_ads = temp[temp.selectedIndex].innerText; }" +
" if(null != document.getElementById('car_no')){ car_no = document.getElementById('car_no').value; }" +
" if( null != document.getElementById('engine_no')){ engine_no = document.getElementById('engine_no').value; }" +

" window.myjs.runOnAndroidJavaScript(car_type,car_ad,car_ads,car_no,engine_no,car_discern,record_no,driver_no) } </script> ");
buf.append("<body><table class='tab'>");
for(int i = 0; i<list.size();i++){
String flag = list.get(i).getFlg();
if("1".equals(flag)){
buf.append("<tr><th>类型：</th>");
buf.append("<td><select id='car_type'>");
List<SelectBean> selectList = list.get(i).getList();
for(int i1=0;i1<selectList.size();i1++){
buf.append("<option value='" + selectList.get(i1).getId()+
"'>"+selectList.get(i1).getName()+"</option>");
}
buf.append("</select></td></tr>");
}else if("2".equals(flag)){
buf.append("<tr><th>前缀：</th>");
buf.append("<td><select id='car_ad'>");
List<SelectBean> selectList = list.get(i).getList();
for(int i1=0;i1<selectList.size();i1++){
buf.append("<option value='" + selectList.get(i1).getId()+
"'>"+selectList.get(i1).getName()+"</option>");
}
buf.append("</select></td></tr>");
}else if("3".equals(flag)){
buf.append("<tr><th>号：</th>");
buf.append("<td><input type='text' name='textfield' id='car_no' /></td></tr>");
}else if("4".equals(flag)){
buf.append("<tr><th>号：</th>");
buf.append("<td><input type='text' name='textfield2' id='engine_no' /></td></tr>");
}else if("5".equals(flag)){
buf.append("<tr><th>码：</th>");
buf.append("<td><input type='text' name='textfield3' id='car_discern' /></td></tr>");
}else if("6".equals(flag)){
buf.append("<tr><th>号：</th>");
buf.append("<td><input type='text' name='textfield4' id='record_no' /></td></tr>");
}else if("9".equals(flag)){
buf.append("<tr><th>号：</th>");
buf.append("<td><input type='text' name='textfield5' id='driver_no' /></td></tr>");
}
}
buf.append("</table></body></html>");
webView.loadDataWithBaseURL(null, buf.toString(), "text/html", "UTF-8", null); class runJavaScript{
public void runOnAndroidJavaScript(final String car_type,final String car_ad,final String car_ads,final String car_no,
final String engine_no,final String car_discern,final String record_no,final String driver_no){
myHandler3.post( new Runnable() {
@Override
public void run() {
}
});
}
}当然还有和java相互交互，我这里是用android的button控件来调用的js，然后在handler.post中对变量赋值
注意：js中window.myjs.runOnAndroidJavaScript这个方法是调用Activity中 webView.addJavascriptInterface(new runJavaScript(), "myjs");方法中的
runJavaScript这个类中的一个方法，myjs这个名字要js和acitivy中的相互对应
webView.requestFocus();要有不然html 中的text 不能输入
webView.getSettings().setJavaScriptEnabled(true); webView可以执行js
还有写js的时候要细心，避免低级失误。
