Question

我正在尝试做一些简单的事情，以前在许多变种中曾经多次被问过，但在我的情况下，我无法做到这一点。

我正在尝试这种情况：

我有一个弹出警告对话框窗口（某个项目），其中有一个删除按钮，如果你按下删除按钮，它会弹出另一个警告对话框“你确定要删除”，是/否的按钮。

如果按是，则会删除该项目，然后我希望关闭这两个对话框。

yes / no对话框本身是关闭的，因为我按下了按钮，但是项目对话框没有关闭，我也无法关闭它...

这是我的代码：

private void popupItem(final int item_id) {

        //setup popup window
        final AlertDialog.Builder builder = new AlertDialog.Builder(
                new ContextThemeWrapper(getActivity(), android.R.style.Holo_Light_ButtonBar_AlertDialog));

        LayoutInflater inflater = getActivity().getLayoutInflater();
        final View dialoglayout = inflater.inflate(R.layout.template_popup_item_alert, null);

        builder.setView(dialoglayout);
        builder.setTitle(getString(R.string.edit_item));

        final AlertDialog item_alert = builder.create();


        //setup delete button
        final ImageButton deleteImageButton = (ImageButton) dialoglayout.findViewById(R.id.template_popup_item_delete);
        deleteImageButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                clickDeleteItem(item_id, item_alert);
            }
        });


        builder.show();

    }

这是删除功能：

private void clickDeleteItem(final int item_id, final AlertDialog item_alert) {
        // create (another) popup delete for "are you sure? yes/no"
        AlertDialog.Builder alert_yesno = new AlertDialog.Builder(getActivity());

        alert_yesno.setTitle(getString(R.string.want_to_remove));

        alert_yesno.setPositiveButton(getString(R.string.yes), new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {

                // ... deleting the item(id)..

                dialog.dismiss(); // close yes/on dialog (redundant - it is closed by itself anyway)
                item_alert.dismiss(); // close the previous popup dialog //~~ NOT WORKING!

            }
        });

        alert_yesno.setNegativeButton(getString(R.string.no), new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                // Canceled.
            }
        });

        alert_yesno.show();
    }

正如你所看到的，我将项目对话框指针传递给yes / no对话框，以便它可以关闭它，但是这行不起作用..

当我到达该行时，调试器上的所有内容都正常运行：

item_alert.dismiss();

它正确指向项目对话框，但此命令不会关闭它.. 我也尝试了.close();命令，但同样的事情，没有任何反应。

我错过了什么？谢谢你！

您正在致电

builder.show();

而不是

item_alert.show();

感谢Nishant Paradamwar，这是正确答案：

public class Popup{
    AlertDialog item_alert; // *creating class object of it*

    private void popupItem(final int item_id) {

            //setup popup window
            final AlertDialog.Builder builder = new AlertDialog.Builder(
                    new ContextThemeWrapper(getActivity(), android.R.style.Holo_Light_ButtonBar_AlertDialog));

            LayoutInflater inflater = getActivity().getLayoutInflater();
            final View dialoglayout = inflater.inflate(R.layout.template_popup_item_alert, null);

            builder.setView(dialoglayout);
            builder.setTitle(getString(R.string.edit_item));




            //setup delete button
            final ImageButton deleteImageButton = (ImageButton) dialoglayout.findViewById(R.id.template_popup_item_delete);
            deleteImageButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    clickDeleteItem(item_id); // *removed 2nd argument*
                }
            });

            item_alert = builder.create(); // *moved the create to bottom so it will contain all parts*
            item_alert.show(); // *calling the alert not builder*

        }

        private void clickDeleteItem(final int item_id) { // *removed second argument, its in class now*
            // create (another) popup delete for "are you sure? yes/no"
            AlertDialog.Builder alert_yesno = new AlertDialog.Builder(getActivity());

            alert_yesno.setTitle(getString(R.string.want_to_remove));

            alert_yesno.setPositiveButton(getString(R.string.yes), new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {

                    // ... deleting the item(id)..

                    item_alert.dismiss(); // close the previous popup dialog //~~ *WORKING NOW!

                }
            });

            alert_yesno.setNegativeButton(getString(R.string.no), new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                    // Canceled.
                }
            });

            alert_yesno.show();
        }
}
