Question

我创建了我的popUp窗口

 public void myPopUp()
    {

        LinearLayout myView = new LinearLayout(getApplicationContext());
         pw = new PopupWindow(getApplicationContext());
         pw.setContentView(myView);
         myView.setBackgroundColor(Color.WHITE);
         pw.setWidth(curWidth-100);
         pw.setHeight(curHeight-100);
         pw.showAtLocation(background, Gravity.CENTER, 0, 0);
   }

并且压倒了backButton被迫解散

public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_BACK) {
            getNewWH();
               middle.removeView(bb);
            if(statusBG==2)
            {
                 log("statusBG = "+statusBG);
                 showFeed();
                 statusBG=1;
            }
            else
            if(statusBG==1)
                { 
                    finish();
                }
            else
            if (pw.isShowing()) {
                 log("here again");
                pw.dismiss();
                log("here");

            }
          return true;  
        }
        return super.onKeyDown(keyCode, event);
    }

你可以理解我 - 当我按下backButton但我现在得到以下错误时，我想要dissmis / hide popupwindow :(

当我按下backButton时，任何人都可以帮助我并告诉我如何纠正dismis弹出窗口吗？

P.S。抱歉我的英语不好，希望你能理解我。问候，彼得。

Answer 1

用于解除PopupWIndow而不是root活动或者通过backpress查看是设置焦点。 popupWindow.setFocusable（真）;

弹出窗口没有焦点，所以当按下后面时，它会关闭主要活动，因为焦点在主要活动上。

Answer 2

请勿使用getApplicationContext（）代替传递上下文或此。

LinearLayout myView = new LinearLayout（context or this）;

无法解雇popUpWindow
