改变轨道和拇指绘制的色调颜色。

switch.getThumbDrawable().setTint(ContextCompat.getColor(this,R.color.colorAccent));

switch.getTrackDrawable().setTint(ContextCompat.getColor(this,R.color.colorAccent));

派对来晚了，但我就是这么做的

风格

 <style name="SCBSwitch" parent="Theme.AppCompat.Light">
        <!-- active thumb & track color (30% transparency) -->
        <item name="colorControlActivated">#46bdbf</item>

        <!-- inactive thumb color -->
        <item name="colorSwitchThumbNormal">#f1f1f1
        </item>

        <!-- inactive track color (30% transparency) -->
        <item name="android:colorForeground">#42221f1f
        </item>
    </style>

颜色

布局

<android.support.v7.widget.SwitchCompat
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:checked="false"
    android:theme="@style/SCBSwitch" />

结果

请参见颜色变化的启用和禁用开关

<androidx.appcompat.widget.SwitchCompat
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                app:thumbTint="@color/white"
                app:trackTint="@drawable/checker_track"/>

在checker_track.xml中:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/lightish_blue" android:state_checked="true"/>
    <item android:color="@color/hint" android:state_checked="false"/>
</selector>

创建一个自定义Switch并覆盖setChecked来改变颜色:

  public class SwitchPlus extends Switch {

    public SwitchPlus(Context context) {
        super(context);
    }

    public SwitchPlus(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public SwitchPlus(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public void setChecked(boolean checked) {
        super.setChecked(checked);
        changeColor(checked);
    }

    private void changeColor(boolean isChecked) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            int thumbColor;
            int trackColor;

            if(isChecked) {
                thumbColor = Color.argb(255, 253, 153, 0);
                trackColor = thumbColor;
            } else {
                thumbColor = Color.argb(255, 236, 236, 236);
                trackColor = Color.argb(255, 0, 0, 0);
            }

            try {
                getThumbDrawable().setColorFilter(thumbColor, PorterDuff.Mode.MULTIPLY);
                getTrackDrawable().setColorFilter(trackColor, PorterDuff.Mode.MULTIPLY);
            }
            catch (NullPointerException e) {
                e.printStackTrace();
            }
        }
    }
}

到目前为止，最好从AppCompat中使用SwitchCompat。v7图书馆。然后，您可以使用简单的样式来更改组件的颜色。

values/themes.xml:

<style name="Theme.MyTheme" parent="Theme.AppCompat.Light">
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">@color/my_awesome_color</item>

    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/my_awesome_darker_color</item>

    <!-- colorAccent is used as the default value for colorControlActivated,
         which is used to tint widgets -->
    <item name="colorAccent">@color/accent</item>

    <!-- You can also set colorControlNormal, colorControlActivated
         colorControlHighlight, and colorSwitchThumbNormal. -->

</style>

参考:Android开发者博客

编辑:

它应该正确应用的方式是通过android:theme="@style/ theme。MyTheme” 这也可以应用到父样式，如EditTexts, RadioButtons, Switches, CheckBoxes和ProgressBars:

<style name="My.Widget.ProgressBar" parent="Widget.AppCompat.ProgressBar">

<style name="My.Widget.Checkbox" parent="Widget.AppCompat.CompoundButton.CheckBox">

Android Studio 3.6解决方案:

yourSwitch.setTextColor(getResources().getColor(R.color.yourColor));

更改颜色XML文件定义值(yourColor)中的文本颜色。
