"使用popupwindow避免将null作为视图根"传递

Question

所以,我的程序运行正常.我只留下三个警告(每个弹出窗口一个),它让我很烦恼,我一直在寻找一个能满足我需求的解决方案,但我似乎无法找到一个.

这是我的代码(其他两个popupwindows相似)

else if(id == R.id.action_resetstats){
        LayoutInflater layoutInflater  = (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
        View popupView = layoutInflater.inflate(R.layout.resetpop, null);
        final PopupWindow popupWindow = new PopupWindow(popupView,LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

        Button yesDismiss = (Button)popupView.findViewById(R.id.yesDismiss);
        yesDismiss.setOnClickListener(new Button.OnClickListener(){
            @Override
            public void onClick(View v){
                SharedPreferences prefs = getSharedPreferences(savedData, Context.MODE_PRIVATE);
                Editor editor = prefs.edit();
                editor.clear();
                editor.commit();

                counterW = 0;
                counterL = 0;
                counterT = 0;
                counterTot = 0;
                timerTime = 3;

                popupWindow.dismiss();
            }
        });    

        popupWindow.showAsDropDown(yeDismiss, 50, 50);


        Button noDismiss = (Button)popupView.findViewById(R.id.noDismiss);
        noDismiss.setOnClickListener(new Button.OnClickListener(){
            @Override
            public void onClick(View v){
                popupWindow.dismiss();
            }
        });    

        popupWindow.showAsDropDown(naDismiss, 50, 50);

</RelativeLayout>

</RelativeLayout>

问题在于解决问题:

View popupView = layoutInflater.inflate(R.layout.resetpop, null);

警告说:

Avoid passing null as the view root (needed to resolve layout parameters on the inflated layout's root element)

任何想法如何解决这个最好的方法？提前致谢!

Answer 1

你可以使用:

context = popupView.getContext();
inflater.inflate(R.layout.resetpop, new LinearLayout(context), false);

那应该解决警告.
