设置com.google.android.material.chip.Chip所选颜色

问题描述

如何设置选定的com.google.android.material.chip.Chip颜色?我不希望它是默认的灰色.这是一个单选芯片组.

How do I set the selected com.google.android.material.chip.Chip color? I don't want it to be the default gray. This is a single selection chip group.

<com.google.android.material.chip.ChipGroup
    android:id="@+id/chipgroup"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginStart="16dp"
    android:layout_marginTop="16dp"
    android:layout_marginEnd="16dp"
    app:checkedChip="@+id/chip_program"
    app:chipSpacingHorizontal="32dp"
    app:chipSpacingVertical="8dp"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/detailText"
    app:singleSelection="true">

    <com.google.android.material.chip.Chip
        android:id="@+id/chip_program"
        style="@style/Widget.MaterialComponents.Chip.Choice"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Program"
        app:chipEndPadding="16dp"
        app:chipStartPadding="16dp" />

    <com.google.android.material.chip.Chip
        android:id="@+id/chip_normal"
        style="@style/Widget.MaterialComponents.Chip.Choice"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/program_normal"
        app:chipEndPadding="16dp"
        app:chipStartPadding="16dp" />
</com.google.android.material.chip.ChipGroup>

推荐答案

只需设置属性 app:chipBackgroundColor 并将颜色状态列表传递给它:

Just set an attribute app:chipBackgroundColor and pass a color state list to it:

<android.support.design.chip.Chip
    android:id="@+id/test"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checkable="true"
    android:clickable="true"
    android:focusable="true"
    app:chipBackgroundColor="@color/bg_chip_state_list"
    app:chipText="Test" />

bg_c​​hip_state_list 看起来像这样:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/colorSecondaryLight" android:state_checked="true" />
    <item android:color="@color/colorPrimaryDark" />
</selector>

不过，我还必须将 android:clickable 设置为 true 才能使这项工作

However I also had to set android:clickable to true to make this work
