单击TextView中的HTML链接会触发奇怪的AndroidRunTimeException

Question

我正从我的网站检索一些HTML并将其放入TextView.此HTML可能包含指向网页,电子邮件等的锚标记.我试图使这些链接可点击,以便当用户点击它时,默认浏览器打开网页.我按照此答案的说明进行此操作 - 如何在TextView中单击链接？以及其他一些在线资源.

所以我的代码是这样的:

TextView para=new TextView(getApplicationContext());    
LayoutParams lpfortext=new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
lpfortext.setMargins(10, 10, 10, 10);
para.setText(Html.fromHtml(e.html()));
para.setMovementMethod(LinkMovementMethod.getInstance());
para.setLinksClickable(true); //error exists on removing this
para.setAutoLinkMask(Linkify.ALL);  //error exists on removing this
para.setLayoutParams(lpfortext);

但是,当我实际点击应用程序中的链接时(在ICS手机上,尚未在模拟器上进行测试),我收到以下错误(堆栈跟踪的快照,最后的全文):

11-18 13:17:51.503: E/AndroidRuntime(6010): android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity  context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

11-18 13:17:51.503: E/AndroidRuntime(6010):     at android.text.method.LinkMovementMethod.onTouchEvent(LinkMovementMethod.java:212)

什么可能导致错误的想法以及如何修复它？

Answer 1

您似乎TextView使用非Activity上下文初始化para 对象,该上下文需要Intent.FLAG_ACTIVITY_NEW_TASK在Intent启动Activity的上下文中设置.

这样可以解决问题

TextView para = new TextView(this);这指的是Activity背景

Answer 2

如果从XML中扩展TextView,请确保使用"getActivity().getLayoutInflater()"扩展包含TextView的布局.这解决了我.
