Question

case R.id.button_next_question:
         if ((this.question_number > -1 + this.total_question) || (this.question_number == -1 + this.total_question))
            {
            new AlertDialog.Builder(getActivity().getApplicationContext()).setTitle("Thank you").show();

}

我想在项目完成问题列表时显示对话框，但是如果执行后如果执行则会出现以下错误

Thank for your reply

finally i  got the solution & its working


if ((this.question_number > -1 + this.total_question) || (this.question_number == -1 + this.total_question))
            {
             LayoutInflater inflater = (LayoutInflater)getActivity().getSystemService
                      (Context.LAYOUT_INFLATER_SERVICE);
             View v1 =inflater.inflate(R.layout.dialog_layout, null);
            new AlertDialog.Builder(getActivity()).setTitle("Thank you")
            .setView(v1)        
            .show();
}

在片段中添加alertdialog框时出错
