约束布局延伸到屏幕边缘

Question

here is the image of the pic i want without the space on the right我有一个嵌套的约束布局。 我正在尝试使用drawable作为约束布局的背景。唯一的问题是它不会延伸到屏幕的边缘。我想要的是将drawable放在屏幕边缘，以便它可以成为屏幕边缘的一部分。

如您所见，我真的不想要那里的空间，只需要将其粘贴在屏幕的右边缘即可。如何确定所有电话中的电话都是scalable。我使用了填充，但是它不显示在屏幕上，因此不建议这样做。我应该添加什么约束以用drawable背景填充屏幕右侧的空间。
