android - 单击即可弹出多个对话框

Question

我有以下代码来生成对话框。流程是这样的

测试结束 -> 用户选择保存或删除 -> 如果用户选择删除，则弹出另一个对话框要求确认删除。

该程序运行良好。但是偶尔会弹出超过 1 个删除对话框。我在某个地方犯了错误吗？

谢谢。

private void buildEndTestDialog(){

    alert = new AlertDialog.Builder(getActivity());
    alert.setTitle("End of Test");
    alert.setCancelable(false);


    alert.setNegativeButton("Save", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            //Save
            alert.dismiss();
        }
    });

    alert.setPositiveButton("Delete", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            buildDeleteDialog();
        }
    });

    alert.show(); 
}

private void buildDeleteDialog() {

    alert = new AlertDialog.Builder(getActivity());
    alert.setTitle("Delete");
    alert.setCancelable(false);
    alert.setMessage("Are you sure you want to delete this result?");
    alert.setNegativeButton("Yes", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            //delete result
        }
    });

    alert.setPositiveButton("No", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {

            dialog.dismiss();
        }
    });

    alert.show(); 
}

尝试..

    private void buildEndTestDialog(){
               ///rest of code
        alert.setPositiveButton("Delete", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                dialog.dismiss();
                buildDeleteDialog();
            }
        });

        alert.show(); 
    }

    private void buildDeleteDialog() {

        ///rest of code

        alert.setPositiveButton("No", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {

                dialog.dismiss();
               buildEndTestDialog();
            }
        });

        alert.show(); 
    }
