最简单的方法是定义轨迹色调，并将色调模式设置为src_over以删除30%的透明度。

android:trackTint="@drawable/toggle_style"
android:trackTintMode="src_over"

toggle_style.xml

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

这是为我工作(需要Android 4.1):

Switch switchInput = new Switch(this);
int colorOn = 0xFF323E46;
int colorOff = 0xFF666666;
int colorDisabled = 0xFF333333;
StateListDrawable thumbStates = new StateListDrawable();
thumbStates.addState(new int[]{android.R.attr.state_checked}, new ColorDrawable(colorOn));
thumbStates.addState(new int[]{-android.R.attr.state_enabled}, new ColorDrawable(colorDisabled));
thumbStates.addState(new int[]{}, new ColorDrawable(colorOff)); // this one has to come last
switchInput.setThumbDrawable(thumbStates);

注意，需要最后添加“default”状态，如下所示。

我看到的唯一问题是，开关的“拇指”现在看起来比背景或开关的“轨道”更大。我认为这是因为我仍然在使用默认的轨道图像，它周围有一些空白空间。然而，当我尝试使用这种技术定制轨道图像时，我的开关似乎有一个1像素的高度，只有一段开/关文本出现。肯定有解决办法，但我还没找到……

Android 5更新

在Android 5中，上面的代码使开关完全消失。我们应该能够使用新的setButtonTintList方法，但对于开关，这似乎被忽略了。但这是可行的:

ColorStateList buttonStates = new ColorStateList(
        new int[][]{
                new int[]{-android.R.attr.state_enabled},
                new int[]{android.R.attr.state_checked},
                new int[]{}
        },
        new int[]{
                Color.BLUE,
                Color.RED,
                Color.GREEN
        }
);
switchInput.getThumbDrawable().setTintList(buttonStates);
switchInput.getTrackDrawable().setTintList(buttonStates);

更新Android 6-7

As Cheruby stated in the comments, we can use the new setThumbTintList and that worked as expected for me. We can also use setTrackTintList, but that applies the color as a blend, with a result that's darker than expected in dark color themes and lighter than expected in light color themes, sometimes to the point of being invisible. In Android 7, I was able to minimize that change that by overriding the track tint mode, but I couldn't get decent results from that in Android 6. You might need to define extra colors that compensate for the blending. (Do you ever get the feeling that Google doesn't want us to customize the appearance of our apps?)

ColorStateList thumbStates = new ColorStateList(
        new int[][]{
                new int[]{-android.R.attr.state_enabled},
                new int[]{android.R.attr.state_checked},
                new int[]{}
        },
        new int[]{
                Color.BLUE,
                Color.RED,
                Color.GREEN
        }
);
switchInput.setThumbTintList(thumbStates);
if (Build.VERSION.SDK_INT >= 24) {
    ColorStateList trackStates = new ColorStateList(
            new int[][]{
                    new int[]{-android.R.attr.state_enabled},
                    new int[]{}
            },
            new int[]{
                    Color.GRAY,
                    Color.LTGRAY
            }
    );
    switchInput.setTrackTintList(trackStates);
    switchInput.setTrackTintMode(PorterDuff.Mode.OVERLAY);
}

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>

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">

可能有点晚了，但是对于开关按钮，toogle按钮不是答案，你必须改变开关xml参数中的drawable:

 android:thumb="your drawable here"

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();
            }
        }
    }
}

作为现有答案的补充:您可以在res/color文件夹中使用选择器自定义拇指和跟踪，例如:

switch_track_selector

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

switch_thumb_selector

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

使用这些选择器自定义轨道和拇指色调:

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

请记住，如果你使用标准Switch和android命名空间的这些属性，它将只适用于API 23和以后，所以使用SwitchCompat与应用命名空间xmlns:app="http://schemas.android.com/apk/res-auto"作为通用解决方案。

结果:
