我需要当用户选择在警告对话框中的项目启动活动。我如何获得上下文传递给意向构造以下code ...

I need to start an activity when the user chooses an item in an alert dialog. How do I get the context to pass to the intent constructor in the following code...

builder.setItems(items, new DialogInterface.OnClickListener() {

        public void onClick(DialogInterface dialog, int item) {

                Intent i = new Intent(<WHAT DO I PUT HERE?>, <new activity>.class);    
                startActivity(i);

      }

});

它是采用内部类的？有什么想法？

Is it the use of the inner class?? Any thoughts?

推荐答案

您可以检索你传递给 AlertDialog.Builder 与 getBaseContext上下文（）。 查看文档here.

You can retrieve the context you have passed to AlertDialog.Builder with getBaseContext(). See the doc here.

所以，这应该工作：

Intent i = new Intent(getBaseContext(), <new activity>.class);    
startActivity(i);
