AlertDialog.dismiss() 不起作用 [英] AlertDialog.dismiss() not working

问题描述

我没有使用否定和肯定按钮.我需要关闭对话框，但 dialog.dismiss() 没有效果.

I am not using the negative and positive buttons. I need to close the dialog but dialog.dismiss() has no effect.

        final AlertDialog.Builder alert = new AlertDialog.Builder(this);
        alert.setView(view);
        alert.setCancelable(false);
        dialog = alert.create();
        goButton.setOnClickListener(new View.OnClickListener() { //goButton is inside view which is inflated inside the dialog

            @Override
            public void onClick(View view) {
                age = (String)spinner.getSelectedItem();
                if(gender == null){
                    Utils.makeToast(context, "Select your gender");
                }else if(age == null || age.toLowerCase().contains("age") || age.equals("")){
                    spinner.performClick();
                }else{
                    Utils.makeToast(context, (String)spinner.getSelectedItem() + " - gender: " +gender);
                    editor.putInt("age", Utils.getIntOrZero(age));
                    editor.putString("gender", gender);
                    editor.commit();
                    dialog.dismiss(); // called but not working
                }
            }
        });

        alert.show();

推荐答案

它不会被关闭，因为您正在调用 AlertDialog.dismiss 的 AlertDialog 不是显示的相同.换句话说，您正在调用 alert.show() 并使用 dialog.dismiss().要修复它，请调用 dialog.show().

It isn't dismissing because the AlertDialog you're calling AlertDialog.dismiss on isn't the same one that's shown. In other words, you're calling alert.show() and using dialog.dismiss(). To fix it call dialog.show().
