Question

好的，所以我一直在努力学习android对话框，这就是我想要做的。我有一个自定义的xml布局用于我想要显示的对话框，我需要在事件触发时更改该布局。这里的问题是，每当我想要改变对话框布局中的任何视图时，窗口每次都会结束，我似乎无法保持它的参数......

以下是我创建对话框的方法：

final Dialog dialog = new Dialog(getActivity());
                        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                        dialog.setContentView(R.layout.dialog_game_details);
                        dialog.setCancelable(false);
                        dialog.show();
                        dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
                        dialog.getWindow().setGravity(Gravity.TOP);

如何访问主要布局元素以添加/删除视图：

final LinearLayout ll_dialog_root_view = (LinearLayout) dialog.findViewById(R.id.ll_dialog_game_root_view);
            final LinearLayout ll_dialog_container_view = (LinearLayout) dialog.findViewById(R.id.ll_dialog_game_body_container);

xml布局文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ll_dialog_game_root_view"

一些左侧字段建议，但您是否考虑过使用PopupWindow而不是对话框？它可能适合您的目的。基本上，您可以将其设置为特定大小，然后根据需要更改其显示的内容。见Android doc - Popupwindow
