Question

在我的项目中，我必须在应用程序的不同部分使用对话框，并且缺点是用于创建和显示每次使用的Dialog的相同代码！所以我决定创建一个创建和显示对话框的功能，无论我需要什么，我只需要调用它，

问题是，我的Dialog上有2个按钮，在重构onClickListener之前我可以轻松使用

dialog.dismiss();
// more codes ...

setOnClickListener中的

但现在使用传入的OnClickListener对象，我无法控制对话框实例... 这是我写的功能

    public static void warningAndErrorDialog(Activity activity, int titleResourceId, int iconResourceId, int contentResourceId
        , HashMap<CustomDialogButton, View.OnClickListener> buttons) {

    Typeface iranSansFont = setFont(activity, FontStyle.IRAN_SANS_REGULAR);
    final Dialog dialog = new Dialog(activity);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.dialog);

    CustomFontTextView cftvTitle = (CustomFontTextView)
            dialog.findViewById(R.id.txtViwDialogTitle);
    if(activity.getString(titleResourceId) != null)
         cftvTitle.setText(titleResourceId);
    else cftvTitle.setText(" ");

    CustomFontTextView cftvContent = (CustomFontTextView)
            dialog.findViewById(R.id.txtViwDialogContent);
    if(activity.getString(contentResourceId) != null)
        cftvContent.setText(contentResourceId);
    else cftvTitle.setText(" ");

    ImageView imgViwDialogTitle = dialog.findViewById(R.id.imgViwDialogTitle);
    imgViwDialogTitle.setImageResource(iconResourceId);


    Button btnYes = null;
    Button btnNo = null;

    for (Map.Entry<CustomDialogButton, View.OnClickListener> button : buttons.entrySet())
        switch (button.getKey()) {
            case YES:
                if (btnYes != null) break;
                btnYes = dialog.findViewById(R.id.btnYes);
                btnYes.setTypeface(iranSansFont);
                if (button.getValue() != null)
                    btnYes.setOnClickListener(button.getValue());
                break;
            case NO:
                if (btnNo != null) break;
                btnNo = dialog.findViewById(R.id.btnNo);
                if (button.getValue() != null) {
                    btnNo.setTypeface(iranSansFont);
                    btnNo.setOnClickListener(button.getValue());
                } else
                    btnNo.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                            dialog.dismiss();
                        }
                    });
                break;
            case OK:
                btnYes = dialog.findViewById(R.id.btnYes);
                btnYes.setText(R.string.ok);
                if (button.getValue() != null) btnYes.setOnClickListener(button.getValue());
                else
                    btnYes.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                            dialog.dismiss();
                        }
                    });
                btnNo = dialog.findViewById(R.id.btnNo);
                btnNo.setVisibility(View.INVISIBLE);
                return;
        }


        dialog.show();
}

案件通知是：我从传递给函数的onClickListener中设置了按钮setOnClickListener。所以我无法控制其内容。 now如何添加语句dialog.dismiss（）; ？我唯一能想到的是找到一种方法将OnClickListener数组传递给setOnCLickListener方法。

一个用于解除对话框，另一个用于设置按钮的实际工作...

ps：我尝试使用setOnTouchListener解除对话框，但正如我所料，这不起作用......： - ？

那我该怎么办？

最终编辑：有人建议

btnYes.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                for (View.OnClickListener callback : callbacks)
                    if (callback != null)
                        callback.onClick(view);
            }
        });

（回调是View.OnClickListener对象的List），这就是＆＃34;如何在单个Button上添加多个onClickListener的确切答案＆＃34;问题

但@greenapps解决方案是最适合我需要的解决方案，谢谢：）

所以我分享了可能涉及的代码的最终版本：D：

Answer 1

btnYes.setOnClickListener(button.getValue());

更改为：

btnYes.setOnClickListener(new View.OnClickListener() { 
   @Override public void onClick(View view) { 
       dialog.dismiss(); 
       button.getValue().onClick(view); 
   }
});

单个按钮上的多个onClickListener
