android - 按钮状态可绘制按下触发多个按钮

Question

将一些按钮的背景设置为可绘制的 custom_button.xml。选择器应该在按下、禁用和默认时更改可绘制对象。出于某种原因，当我按下 View 中的任何按钮时，布局中的最后一个按钮也将其可绘制对象设置为 rounded_corner_pressed。这都是通过选择器完成的。我试过添加 state_focus 无济于事。有任何想法吗？

自定义按钮.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_pressed="true" f
        android:drawable="@drawable/rounded_corner_pressed" />
    <item
        android:state_enabled="false"
        android:drawable="@drawable/rounded_corner_disabled" />
    <item
        android:drawable="@drawable/rounded_corner" />
</selector>

rounded_corner.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@android:color/white"/>

您可以简化您的布局。 对于您的按钮，只需使用 MaterialButton在Material Components library .

类似于:

<com.google.android.material.button.MaterialButton
    android:text="BUTTON"
    app:cornerRadius="8dp"
    app:strokeWidth="1dp"
    app:strokeColor="@color/myColor"
    android:backgroundTint="@color/myselector"
    ../>

对于 TextView，您可以使用 TextInputLayout .

类似于:

<com.google.android.material.textfield.TextInputLayout
    app:hintEnabled="false"
    style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
    app:boxCornerRadiusBottomStart="8dp"
    app:boxCornerRadiusBottomEnd="8dp"
    app:boxCornerRadiusTopEnd="8dp"
    app:boxCornerRadiusTopStart="8dp"
    ...>

    <com.google.android.material.textfield.TextInputEditText
        android:text="Text"
        .../>

</com.google.android.material.textfield.TextInputLayout>
