Android 尝试以编程方式关闭警报对话框

我正在尝试做一些简单的事情，这在很多变体中被多次询问，但在我的案例中我无法做到

我正在尝试这样的场景：

我有一个弹出警报对话框窗口（某些项目），其中有一个删除按钮，如果您按下删除按钮，它将弹出另一个警报对话框“您确定要删除吗”和是/否按钮

如果您按yes（是），它将删除该项，然后我希望两个对话框都关闭

“是/否”对话框是自动关闭的，因为我按下了按钮，但“项目”对话框没有关闭，我无法以任何方式将其关闭

这是我的密码：

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();

    }

以下是删除功能：

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();
    }

如您所见，我正在将项对话框指针传递到yes/no对话框中，以便它可以关闭它，但该行不起作用

当我到达以下行时，调试器上的一切都正常运行：

item_alert.dismiss();

它正确地指向“项”对话框，但此命令无法关闭它。。 我尝试了

.close（）命令，但同样的事情，什么也没发生

我错过了什么？
谢谢你
 你在打电话吗

builder.show（）

而不是

item_alert.show（）
感谢Nishant Paradamwar，以下是正确答案：

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();
        }
}

设置所有标题、setPositiveButton、setNegativeButton和消息，然后调用builder.create（）；它将返回AlertDialog对象，您可以显示/取消该对象，但请记住，在构建器之后无法操作构建器。create（）被称为doh nice，我这次做对了！我需要将答案与您之前创建类对象的答案结合起来。。非常感谢你！！我为此挣扎了几天！
