设置自动连接属性

Question

我有数组的一些网址，当我点击文本查看它需要打开网页，但即时得到错误我的代码是

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的输出

Answer 1

嗨，我想你应该使用WebView打开任何链接。你可以从这里得到一个想法，如何处理WebView的简单示例。链接如下： - WebView Example。 我希望这可以帮助你很多。

我觉得在你的logcat你的问题的解决方案可以通过以下链接满足： - Your Logcat Issue

Answer 2

看来你已经开始从出侧Activity

简单简短的回答的上下文的Activity你的代码，你开始的活动确保该背景下，启动它是一个Activity否则应确保其用意标志设置为Intent.FLAG_ACTIVITY_NEW_TASK

例如

Intent intent = new Intent(mContext, SomeActivity.class); 
intent.setFlag(Intent.FLAG_ACTIVITY_NEW_TASK); 
.. 
... 
.. 

mContext.startActivity(intent); 

Answer 3

检查Nammari's响应，或者如果有一个getView（）方法中的代码，以避免该异常

“从一个活动上下文之外调用startActivity（）需要 的FLAG_ACTIVITY_NEW_TASK标志。这真的是你想要的“

可能你需要：

LinearLayout l = new LinearLayout(parent.getContext()); 
... 
... 
LinearLayout layout = new LinearLayout(parent.getContext()); 

，而不是

LinearLayout l = new LinearLayout(this); 
... 
... 
LinearLayout layout = new LinearLayout(this); 

Answer 4

另外：如果你表现出在片段适配器链接，不要创建它像这样

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

改为致电

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

适配器在这两种情况下工作正常，但链接只在最后一个工作。

Answer 5

变化LinearLayout l = new LinearLayout(this);到LinearLayout l = new LinearLayout(getParent.getApplicationContext());
