Question

这是来自同一question in Spanish的翻译，由于我认为您可以提供比我们的小社区更多的信息，因此我将其发布在这里。

我从出生起就一直是盲人，我正在大学里学习系统工程的职业。

我想知道如何在Android Studio中对应用程序的图形界面进行编程。我搜索了教程，发现其中一些教程，例如，添加一个按钮，将其拖到您想要的位置，然后它会自动添加到其中。

在我看来，这是不可能的，因为我的屏幕阅读器没有资格进行此类工作。因此，我的问题是如何在看不见的情况下对android图形界面进行编程？

Answer 1

您可以使用XML对布局进行编码。用XML编写使您可以完全控制如何编码布局。我也有视觉障碍，而且多年来我都在用XML编码布局。在tutorialpoint上有一个很好的教程可以帮助您。另外，我将从我的应用程序粘贴布局的xml代码示例之一，以供您参考。您可以在链接下面找到代码：教程： https://www.tutorialspoint.com/android/android_user_interface_layouts

XML布局示例：

Traceback (most recent call last):
  File "/home/pata/venvs/lib/python3.6/site-packages/mongoengine/document.py", line 389, in save
    object_id = self._save_create(doc, force_insert, write_concern)

pymongo.errors.DuplicateKeyError: E11000 duplicate key error collection: test_db.search_word index: word_1 dup key: { : "word" }

During handling of the above exception, another exception occurred:
