android - 设置自动链接属性

Question

当我点击需要打开页面的 TextView 时，我在数组中有一些 url，但我收到错误，我的代码是

LinearLayout l = new LinearLayout(this);
    l.setOrientation(LinearLayout.VERTICAL);
    String[] textArray={"www.google.co.in","www.gmail.com","www.facebook.com"};
    int length=textArray.length;
    LinearLayout layout = new LinearLayout(this);
    setContentView(layout);
    layout.setOrientation(LinearLayout.VERTICAL);        
    for(int i=0;i<length;i++)
    {
        TextView tv=new TextView(getApplicationContext());
        tv.setText(textArray[i]);
        layout.addView(tv);
       Linkify.addLinks(tv, Linkify.WEB_URLS);
       tv.setMovementMethod(LinkMovementMethod.getInstance())

LogCat output

Answer 1

另外:如果你在 fragment 中显示适配器中的链接，不要这样创建

    adapter = new ListAdapter(getActivity().getApplicationContext(),mStrings,dispWidth,dispHeight);

而是调用

    adapter = new ListAdapter(getActivity(),mStrings,dispWidth,dispHeight);

适配器在这两种情况下都能正常工作，但链接仅在最后一种情况下有效。
