android - 通过后退按钮关闭弹出窗口

Question

我想通过单击弹出窗口外部或后退按钮来关闭弹出窗口，但是当单击后退按钮时我的应用程序退出，而不是退出应用程序我想关闭弹出窗口。

这是我的代码，

ivmainmenu.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

        LayoutInflater layoutInflater = (LayoutInflater)getBaseContext()
                .getSystemService(LAYOUT_INFLATER_SERVICE);  
        View popupView = layoutInflater.inflate(R.layout.popupwindow, null);  
        final PopupWindow popupWindow = new PopupWindow(popupView,LayoutParams.FILL_PARENT,
                LayoutParams.WRAP_CONTENT);  
        popupWindow.showAsDropDown(ivmainmenu, 0,14);
        popupView.setPadding(0, 0, 0, 10);
        popupWindow.showAsDropDown(ivmainmenu);

        popupWindow.setBackgroundDrawable(new BitmapDrawable());
        popupWindow.setOutsideTouchable(false);

        TextView tvpopupwork = (TextView)popupView.findViewById(R.id.tvpopupwork);
        TextView tvpopupabout = (TextView)popupView.findViewById(R.id.tvpopupabout);
        TextView tvpopupservices = (TextView)popupView.findViewById(R.id.tvpopupservices);
        TextView tvpopupcontact = (TextView)popupView.findViewById(R.id.tvpopupcontact);

        Typeface typeFace2 =  Typeface.createFromAsset(getAssets(),"fonts/arboriaboldregular.ttf");
        tvpopupwork.setTypeface(typeFace2);
        tvpopupabout.setTypeface(typeFace2);
        tvpopupservices.setTypeface(typeFace2);
        tvpopupcontact.setTypeface(typeFace2);

        tvpopupwork.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent intent = new Intent(Home.this,Ourwork.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                startActivity(intent);
            }
        });

        tvpopupabout.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent intent = new Intent(Home.this,Aboutus.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                startActivity(intent);  
            }
        });

        tvpopupservices.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                Intent intent = new Intent(Home.this,Services.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                startActivity(intent);
            }
        });

        tvpopupcontact.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                Intent intent = new Intent(Home.this,Contact.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                startActivity(intent);
            }
        });

        ivmainmenu.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                popupWindow.dismiss();
            }
        });
    }
});

它给了我想要的结果，但是当我关闭菜单时，它不会再次打开，我想再次打开它，我该怎么办？谢谢。

替换

popupWindow.setOutsideTouchable(false);

有了这个

popupWindow.setOutsideTouchable(true);
popupWindow.setFocusable(true);
