Android:如何从警报对话框启动 Activity

问题描述

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);

      }

});

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

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

So this should work:

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