不能忽视popUpWindow

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);
   }

并为dissmis按下被覆盖的backButton

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);
    }

正如你所理解的-当我按下backButton时，我想显示/隐藏弹出窗口，但现在我得到了下面的错误:(

有没有人可以帮助我，告诉我当我按下backButton时，如何纠正弹出的错误？

附注：很抱歉我的英语不好，希望你能理解我。打招呼，彼得。

Answer 1

不要使用getApplicationContext()代替传递context或this。

LinearLayout myView =新的上下文(LinearLayout or this)；

Answer 2

取消PopupWIndow而不是根活动或视图的方法是设置焦点。PopupWindow.setFocusable(真)；

弹出窗口没有焦点，所以当按back时，它会关闭主活动，因为焦点在主活动上。
