Quite hard to understand if you have doubts about button design and states or button position. If it's a design issue, you should create your button states on your favorite software, as example, photoshop. Then, in your android layouts you point your button background src to a drawable XML containing all button states.
如果您对按钮设计和状态或按钮位置有疑问，则很难理解。如果是设计问题，您应该在您喜欢的软件（例如 photoshop）上创建按钮状态。然后，在您的 android 布局中，您将按钮背景 src 指向包含所有按钮状态的可绘制 XML。
Example XML for button:
按钮的 XML 示例：
<Button android:id="@+id/back"
android:layout_width="184px" android:layout_height="44px"
android:background="@+drawable/back" />
After this, you need your custom picture for the button, and the button XML on your drawables folder, here's the XML you need for your button:
在此之后，您需要按钮的自定义图片，以及 drawables 文件夹中的按钮 XML，这是按钮所需的 XML：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="@drawable/button_pressed" /> <!-- pressed -->
<item android:state_focused="true"
android:drawable="@drawable/button_focused" /> <!-- focused -->
<item android:drawable="@drawable/button_normal" /> <!-- default -->
</selector>
