Question

我想通过相同的按钮关闭弹出按钮但是当我再次点击按钮时，它重新打开窗口而不是关闭它，当我在窗口外面任何地方点击时也应该关闭窗口，任何人都可以帮助我吗？

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

                            // TODO Auto-generated method stub

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

                    });

                }
         }
            });

请帮助我，我没有得到任何解决方案，谢谢。

Answer 1

制作一个类似showDialog的布尔标志。 showDialog = false第一次

if(!showDialog){
display popup
showDialog=true
}else{
popup.dismiss();
showDialog=false;
}

Answer 2

尝试将变量isShowing设为全局静态变量，并将其置于onClickListener之外，因为在您的代码中，每次单击View时，它都会再次重新初始化值false所以你永远不会做所需的行为

public class ClassName .....{

                 boolean isShowing = false;
                 ...
                 ...
                 ...
                 ivmainmenu.setOnClickListener(new OnClickListener() {

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

        if(isShowing)
        {
             PopupWindow popupWindow = null;
            popupWindow.dismiss();
             isShowing=false;
        }
        else
        {
         isShowing=true;
                 ...
                 ...
                 ...

//添加isShowing = true;你的其他部分代码中的陈述

ivmainmenu.setOnClickListener（new OnClickListener（）{

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

        boolean isShowing = false;
        if(isShowing)
        {
             PopupWindow popupWindow = null;
            popupWindow.dismiss();
             isShowing=false;
        }
        else
        {

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

                isShowing=true; //This statement will solve your problem.

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