Android（java）学习笔记90：TextView 添加超链接(两种实现方式)

LinearLayout layout = new LinearLayout(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT);
TextView textView = new TextView(this);
String html = "有问题：\n";
html +="<a href='http://www.baidu.com'>百度一下</a>";//注意这里必须加上协议号，即http://
//public static Spanned fromHtml(String source):这里返回的是Spanned,由于这个Spanned是继承自CharSequence
//所以,可以不经过类型转化直接用CharSequence接收Spanned类型
CharSequence charSequence = Html.fromHtml(html);
textView.setText(charSequence);
//设置该句使文本TextView的超连接起作用,LinkMovementMethod.getInstance():返回一个MovementMethod实例
textView.setMovementMethod(LinkMovementMethod.getInstance());
layout.addView(textView);
this.setContentView(layout,params);

LinearLayout layout = new LinearLayout(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT);
TextView textView = new TextView(this);
String html = "有问题：\n";
html+="www.baidu.com";//这里即使不加协议HTTP;也能自动被系统识别出来
textView.setText(html);
//这里即使不加协议好HTTP；也能自动被系统识别出来
textView.setAutoLinkMask(Linkify.ALL);
//设置该句使文本TextView的超连接起作用
textView.setMovementMethod(LinkMovementMethod.getInstance());
layout.addView(textView);
this.setContentView(layout,params);
