如何使用textview和android

我想创建一个对话框,其中包含我的网站(在android上)的链接,并希望手机的浏览器打开时,用户点击链接。我现在有:

@Override 
protected Dialog onCreateDialog (int id){
Dialog dialog = new Dialog(MyActivity.this);                                                

dialog.setContentView(R.layout.custom_dialog);
dialog.setTitle("MyTittle");
ImageView image = (ImageView)dialog.findViewById(R.id.image); 

image.setImageResource(R.drawable.launcher_icon);
TextView lblClickable = (TextView)findViewById(R.id.text); 
String htmlText = "Link to my <a HREF='http://www.rainbowbreeze.it'>site</a>"; 
 lblClickable.setText(Html.fromHtml(htmlText));
//needed to enable click on the link     
lblClickable.setMovementMethod(LinkMovementMethod.getInstance());
return dialog; }

上面的代码在包含 lblClickable.setText(Html.fromHtml(htmlText));
