Question

我希望用同一个PopupWindow关闭Button，但是当我再次点击Button时，它会重新打开PopupWindow而不是关闭它，也应该当我点击PopupWindow以外的任何地方时，关闭PopupWindow，有人可以帮助我吗？

这是我的代码，

ivmainmenu.setOnClickListener(new OnClickListener() {

         @SuppressWarnings("null")
            @Override
            public void onClick(View v) {

             if(isShowing)
                {
                     PopupWindow popupWindow = null;
                    popupWindow.dismiss();
                     isShowing=false;
                }
                else
                {
                 isShowing=true;
                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.setBackgroundDrawable(new BitmapDrawable());
                        popupWindow.setOutsideTouchable(true);
                        popupWindow.setFocusable(true);

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

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

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

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

                }
         }
            });

当我尝试这段代码时，当我再次点击同一个按钮时出现错误，这是我得到的logcat错误，

任何人都可以帮忙解决这个错误吗？谢谢。

按照我的方式：

    int x=1;
    ivmainmenu.setOnClickListener(new OnClickListener() {

         @SuppressWarnings("null")
            @Override
            public void onClick(View v) {
           if((x%2)!=0){ 
            //Dismiss PopUp
           }else{
            //Show PopUp
           }
           x++;   
       }
    });

并且还全局定义了您的popupWindow并制作了

popupWindow.setOutsideTouchable(false);
popupWindow.setCanceledOnTouchOutside(false)

<强>更新

PopupWindow popupWindow = null;
Boolean isShowing=false;
ivmainmenu.setOnClickListener(new OnClickListener() {

     @SuppressWarnings("null")
        @Override
        public void onClick(View v) {

         if(isShowing)
            {
              if(popupWindow != null && popupWindow.isShowing()){
                 popupWindow.dismiss();
                 }
                isShowing=false;
            }

更改onClick()方法如下：

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


                        if(popupWindow != null && popupWindow.isShowing()){
                           popupWindow.dismiss();
                        }

                    }

如果您想要使用相同的按钮关闭弹出窗口并单击外部的任何位置，则必须实现

触摸拦截器并在操作 MotionEvent.ACTION_OUTSIDE 时关闭弹出窗口。
使用 setFocusable（true）

可聚焦

设置可聚焦功能可确保弹出可以抓取外部触摸事件，因为它还会捕获菜单项或按钮上的点击，它确保弹出窗口如果已经显示则不会再次启动。

要将上述逻辑放在代码中，您必须执行以下操作。

 final MenuItem popupMenu= menu.findItem(R.id.action_open_popup);
    popupMenu.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
        @Override
        public boolean onMenuItemClick(MenuItem item) {
            if (window == null) {
                View contentView = getLayoutInflater(null).inflate(R.layout.popup_menu, null);
                window = new PopupWindow(contentView, ActionBar.LayoutParams.WRAP_CONTENT, ActionBar.LayoutParams.WRAP_CONTENT);
                window.setBackgroundDrawable(new BitmapDrawable(getResources(), ""));
                window.setOutsideTouchable(true);
                window.setFocusable(true);
                window.setTouchInterceptor(new View.OnTouchListener() {
                    @Override
                    public boolean onTouch(View v, MotionEvent event) {
                        if(event.getAction()==MotionEvent.ACTION_OUTSIDE){
                            window.dismiss();
                            return true;
                        }
                        return false;
                    }
                });
            }
            //anchor as the menuitem this is in fragment so.
            window.showAsDropDown(getActivity().findViewById(R.id.action_open_popup));
            return true;
        }
    });

popupwindow通过相同的按钮关闭问题
