textView 超链接 textView 添加超链接(两种实现方式)

public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout layout = new LinearLayout(this);
LayoutParams params = new 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://。

//否则，系统会以为该链接是activity，而实际这个activity不存在，程序就崩溃。
CharSequence charSequence = Html.fromHtml(html);

textView.setText(charSequence);

textView.setMovementMethod(LinkMovementMethod.getInstance());
layout.addView(textView);
this.setContentView(layout,params);
}

public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout layout = new LinearLayout(this);
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT);
TextView textView = new TextView(this);
String html = "有问题：\n";
html+="www.baidu.com";//这里即使不加协议好HTTP；也能自动被系统识别出来。
textView.setText(html);
textView.setAutoLinkMask(Linkify.ALL);
textView.setMovementMethod(LinkMovementMethod.getInstance());
layout.addView(textView);
this.setContentView(layout,params);
}
