Android学习-第53天

今天的任务为改变主题、添加主题颜色以及覆盖主题属性、修改按钮属性，代码如下：

styles.xml:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/red</item>
        <item name="colorPrimaryDark">@color/dark_red</item>
        <item name="colorAccent">@color/gray</item>

        <item name="android:windowBackground">@color/soothing_blue</item>
        <item name="buttonStyle">@style/BeatBoxButton</item>
    </style>

    <style name="BeatBoxButton">
        <item name="android:background">@color/dark_blue</item>
    </style>

</resources>

list_item_sound.xml:

<?xml version="1.0" encoding="utf-8"?>
<layout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">
    <data>
        <variable
            name="viewModel"
            type="com.bignerdranch.android.beatbox.SoundViewModel"/>
    </data>
    <Button
        android:layout_width="match_parent"
        android:layout_height="120dp"
        android:onClick="@{() -> viewModel.onButtonClicked()}"
        android:text="@{viewModel.title}"
        tools:text="Sound name"/>
</layout>
