当我在弹出窗口中单击微调器时，活动完成

Question

大家好，我在弹出窗口中单击微调框时，我的活动结束了。但我没有针对小米和htc的三星手机出现此错误。我无法理解为什么我只有小米和htc出现此错误。我尝试解决了它，但没有解决。我发现了诸如this之类的问题 但是它没有解决这个问题。他使用对话框屏幕ı不想使用对话框屏幕。 这是我的源代码：

public void popup_show(){
    inflater = (LayoutInflater) anaurun.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    layout = inflater.inflate(R.layout.adet_popup, (ViewGroup) findViewById(R.id.adet_layout));
    adet_spin = layout.findViewById(R.id.adet_spin);

    DisplayMetrics displayMetrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
    int height = displayMetrics.heightPixels;
    int width = displayMetrics.widthPixels;
    popWin = new PopupWindow(layout, width, height, true);
    popWin.showAtLocation(layout, Gravity.CENTER, 0, 0);
    adapter = new spinner_adapter(this, adet);
    adet_spin.setAdapter(adapter);
    adet_spin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            secili_adet=Integer.valueOf(adet.get(position));
            Log.d("adet",secili_adet+"");
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });
}

并且我有这样的错误：
