Android seekbar - 没有颜色色调参数

Question

看图中安装了什么

模拟器设置为 4.4.2。 MinSDK 设置为 16。

错误:找不到与给定名称匹配的资源:attr 'android:progressBackgroundTint' 等

Seekbar 没有以下参数:colorControlActivated、progressbackgroundtint、progresstint、thumbtint

如何改变搜索栏的颜色？

Main.axml 搜索栏样式:

<SeekBar
    p1:layout_width="250dp"
    p1:layout_height="wrap_content"
    ... />

How to change color of seekbar?

Android SeekBar自定义 Material 样式，可引用:

http://www.zoftino.com/android-seekbar-and-custom-seekbar-examples

创建自定义 SeekBar 样式:

<style name="MySeekBar" parent="Widget.AppCompat.SeekBar">
    <item name="android:progressBackgroundTint">#f4511e</item>
    <item name="android:progressTint">#388e3c</item>
    <item name="android:colorControlActivated">#c51162</item>
</style>

在你的 axml 中使用它:

<SeekBar
    android:id="@+id/mySeekBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    style="@style/MySeekBar"
    />

效果:

更新:

请确保您已在 axml 中添加 xmlns:android="http://schemas.android.com/apk/res/android，如果您已将此添加到您的 axml 中，请发布完整的 axml 文件。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <SeekBar
        android:id="@+id/mySeekBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        style="@style/MySeekBar"
        />
</LinearLayout>
