Question

我尝试使用以下链接更改SwitchCompat的颜色：

How to change the color of a SwitchCompat

请注意我的开关中的低对比度：

The SwitchCompat

但是在更改所有相关颜色值后，SwitchCompat的轨道（更亮的灰色）保持不变。除了颜色，我不想改变外观。拇指是粉红色的，我希望轨道有一些对比。我错过了在styles.xml中定义一个值吗？

我尝试了这些值（随机非白色）：

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/first</item>
    <item name="colorPrimaryDark">@color/second</item>
    <item name="colorAccent">@color/third</item>
   ...
    <item name="colorControlActivated">@color/first</item>
    <item name="colorControlHighlight">@color/first</item>
    <item name="colorControlNormal">@color/second</item>
    <item name="colorSwitchThumbNormal">@color/second</item>
    <item name="colorButtonNormal">@color/second</item>
...>

Answer 1

我有同样的问题并解决了它。

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
   ...
   <!-- Active thumb color & Active track color(30% transparency) -->
   <item name="colorControlActivated">@color/theme</item>
   <!-- Inactive thumb color -->
   <item name="colorSwitchThumbNormal">@color/grey300</item>
   <!-- Inactive track color(30% transparency) -->
   <item name="android:colorForeground">@color/grey600</item>
   ...
</style>

我阅读了app compat代码，并了解它。

android.support.v7.internal.widget.TintManager.java

private ColorStateList getSwitchTrackColorStateList() {
    if (mSwitchTrackStateList == null) {
        final int[][] states = new int[3][];
        final int[] colors = new int[3];
        int i = 0;

        // Disabled state
        states[i] = new int[] { -android.R.attr.state_enabled };
        colors[i] = getThemeAttrColor(android.R.attr.colorForeground, 0.1f);
        i++;

        states[i] = new int[] { android.R.attr.state_checked };
        colors[i] = getThemeAttrColor(R.attr.colorControlActivated, 0.3f);
        i++;

        // Default enabled state
        states[i] = new int[0];
        colors[i] = getThemeAttrColor(android.R.attr.colorForeground, 0.3f);
        i++;

        mSwitchTrackStateList = new ColorStateList(states, colors);
    }
    return mSwitchTrackStateList;
}

Answer 2

以下是针对特定 SwitchCompat 更改曲目和拇指颜色以编程方式的 AppCompat 方式。对于此示例，我已将thumbColor硬编码为红色。理想情况下，您可以通过第二个方法参数设置颜色。

请注意，选中开关时，会显示纹波。下面的代码不会改变波纹颜色。

public static void setSwitchColor(SwitchCompat v) {
    // thumb color of your choice
    int thumbColor = Color.RED;

    // trackColor is the thumbColor with 30% transparency (77)
    int trackColor = Color.argb(77, Color.red(thumbColor), Color.green(thumbColor), Color.blue(thumbColor));

    // setting the thumb color
    DrawableCompat.setTintList(v.getThumbDrawable(), new ColorStateList(
            new int[][]{
                    new int[]{android.R.attr.state_checked},
                    new int[]{}
            },
            new int[]{
                    thumbColor,
                    Color.WHITE
            }));

    // setting the track color
    DrawableCompat.setTintList(v.getTrackDrawable(), new ColorStateList(
            new int[][]{
                    new int[]{android.R.attr.state_checked},
                    new int[]{}
            },
            new int[]{
                    trackColor,
                    Color.parseColor("#4D000000") // full black with 30% transparency (4D)
            }));
}

Answer 3

 Here is Switch Layout
 -Adding theme to your switch to change the color of track.Check the style given below:-.

**Switch Compact**
  <android.support.v7.widget.SwitchCompat
                android:id="@+id/goOnlineBtn"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                app:theme="@style/Switch_style/>


**Switch_style**
   <style name="Switch_style" parent="Theme.AppCompat.Light">
        <!-- active thumb & track color (30% transparency) -->
        <item name="colorControlNormal">@android:color/white</item>
        <item name="colorControlActivated">@android:color/blue</item>
        <item name="colorSwitchThumbNormal">@android:color/white</item>
        <item name="trackTint">@color/white</item>
   </style>

trackTint将改变曲目颜色

Answer 4

如果您要对轨道的颜色进行夸张。可以使用此解决方案。

track selector.xml

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

其中“ checked_color”和“ unchecked_color”是您选择的颜色。

styles.xml

<style name="mySwitchStyle" parent="@style/Widget.AppCompat.CompoundButton.Switch">
       <!-- do here for additional costumization on thumb, track background,text appearance -->


    </style>


<style name="mySwitchTheme" parent="ThemeOverlay.AppCompat.Light">
        <item name="switchStyle">@style/mySwitchStyle</item>
        <item name="colorControlActivated">@color/red</item>
        <item name="colorControlNormal">@color/colorAccent</item>
        <item name="trackTint">@color/track_selector</item>
    </style>

布局文件

<android.support.v7.widget.SwitchCompat
        android:theme="@style/mySwitchTheme"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />

Answer 5

如果您想在一个活动中使用多种颜色的更多开关，您可以使用此解决方案（基于@Konifar的主题）：

<style name="CustomSwitchTheme" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
    <!-- Active thumb color & Active track color(30% transparency) -->
    <item name="colorControlActivated">@color/custom</item>
    <!-- Inactive thumb color -->
    <item name="colorSwitchThumbNormal">#E0E0E0</item>
    <!-- Inactive track color(30% transparency) -->
    <item name="android:colorForeground">#757575</item>
</style>

其中@color/custom是激活开关时的拇指颜色。

然后以这种方式将此主题应用于SwitchCompat：

<android.support.v7.widget.SwitchCompat
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/CustomSwitchTheme" />

Answer 6

我遇到了同样的问题。最后用这个Kotlin代码以编程方式解决了它

fun tintSwitchButton(sw: SwitchCompat, resolvedColor: Int) {
    val states = arrayOf(
            intArrayOf(-android.R.attr.state_pressed),
            intArrayOf(android.R.attr.state_pressed)
    )

    DrawableCompat.setTintList(sw?.trackDrawable, ColorStateList(
            states,
            intArrayOf(resolvedColor, resolvedColor)
    ))

    DrawableCompat.setTintList(sw?.thumbDrawable, ColorStateList(
            states,
            intArrayOf(Color.WHITE, Color.WHITE)
    ))
}

函数调用是

tintSwitchButton(switchCompat, Color.rgb(214, 0, 0))

您还可以创建扩展功能：

fun SwitchCompat.tint(resolvedColor: Int) {
    val states = arrayOf(
        intArrayOf(-android.R.attr.state_pressed),
        intArrayOf(android.R.attr.state_pressed)
    )

    DrawableCompat.setTintList(trackDrawable, ColorStateList(
        states,
        intArrayOf(resolvedColor, resolvedColor)
    ))

    DrawableCompat.setTintList(thumbDrawable, ColorStateList(
        states,
        intArrayOf(Color.WHITE, Color.WHITE)
    ))
}

所以电话会更容易

switchCompat.tint(Color.rgb(214,0,0))

Answer 7

只需使用colorControlActivated设置SwitchCompat的轨道和拇指的颜色。

如果未设置，默认的colorControlActivated颜色将使用colorAccent。（从经验来看，仍未找到源代码中的位置）。

源代码发生了变化，但仍然不喜欢@Ovidiu说。但仍然感谢他让我知道从源代码中找到答案。

mThumbDrawable = a.getDrawable(R.styleable.SwitchCompat_android_thumb);

最终将调用以下方法。

/frameworks/support/v7/appcompat/src/android/support/v7/widget/AppCompatDrawableManager.java

private ColorStateList createSwitchTrackColorStateList(Context context) {
    final int[][] states = new int[3][];
    final int[] colors = new int[3];
    int i = 0;

    // Disabled state
    states[i] = ThemeUtils.DISABLED_STATE_SET;
    colors[i] = getThemeAttrColor(context, android.R.attr.colorForeground, 0.1f);
    i++;

    states[i] = ThemeUtils.CHECKED_STATE_SET;
    colors[i] = getThemeAttrColor(context, R.attr.colorControlActivated, 0.3f);
    i++;

    // Default enabled state
    states[i] = ThemeUtils.EMPTY_STATE_SET;
    colors[i] = getThemeAttrColor(context, android.R.attr.colorForeground, 0.3f);
    i++;

    return new ColorStateList(states, colors);
}

private ColorStateList createSwitchThumbColorStateList(Context context) {
    final int[][] states = new int[3][];
    final int[] colors = new int[3];
    int i = 0;

    final ColorStateList thumbColor = getThemeAttrColorStateList(context,
            R.attr.colorSwitchThumbNormal);

    if (thumbColor != null && thumbColor.isStateful()) {
        // If colorSwitchThumbNormal is a valid ColorStateList, extract the default and
        // disabled colors from it

        // Disabled state
        states[i] = ThemeUtils.DISABLED_STATE_SET;
        colors[i] = thumbColor.getColorForState(states[i], 0);
        i++;

        states[i] = ThemeUtils.CHECKED_STATE_SET;
        colors[i] = getThemeAttrColor(context, R.attr.colorControlActivated);
        i++;

        // Default enabled state
        states[i] = ThemeUtils.EMPTY_STATE_SET;
        colors[i] = thumbColor.getDefaultColor();
        i++;
    } else {
        // Else we'll use an approximation using the default disabled alpha

        // Disabled state
        states[i] = ThemeUtils.DISABLED_STATE_SET;
        colors[i] = getDisabledThemeAttrColor(context, R.attr.colorSwitchThumbNormal);
        i++;

        states[i] = ThemeUtils.CHECKED_STATE_SET;
        colors[i] = getThemeAttrColor(context, R.attr.colorControlActivated);
        i++;

        // Default enabled state
        states[i] = ThemeUtils.EMPTY_STATE_SET;
        colors[i] = getThemeAttrColor(context, R.attr.colorSwitchThumbNormal);
        i++;
    }

    return new ColorStateList(states, colors);
}

Answer 8

SwitchCompat是“材料设计”小部件。当我的活动扩展 AppCompatActivity 并且android：theme =“ @ style / mySwitch”正常工作时。

Answer 9

开发人员可以通过以下方式更改SwitchCompat的可绘制轨迹：
首先，在根目录布局中，写xmlns:SwitchCompat="http://schemas.android.com/apk/res-auto"
然后：

    <android.support.v7.widget.SwitchCompat
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="30dp"
        android:thumb="@drawable/your_switch_thumb"
        SwitchCompat:track="@drawable/your_switch_track_selector" 
        />

your_switch_track_selector可以位于的位置：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/switch_ios_track_on" android:state_checked="true" />
    <item android:drawable="@drawable/switch_ios_track_off" android:state_checked="false" />
</selector>

1.switch_ios_track_on:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    >
    <solid android:color="#4EDA62" />
    <corners android:radius="20dp" />
</shape>

2.switch_ios_track_off:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    >
    <solid android:color="#E3E3E3" />
    <corners android:radius="20dp" />
</shape>

简单容易..

Answer 10

使用材料组件库提供的 MaterialSwitch 。

使用 materialThemeOverlay 属性覆盖Switch的应用颜色。

  <style name="CustomWidget.MaterialComponents.CompoundButton.Switch" parent="Widget.MaterialComponents.CompoundButton.Switch">
    <item name="materialThemeOverlay">@style/CustomCompoundButton_Switch</item>
  </style>
  <style name="CustomCompoundButton_Switch" >
    <item name="colorSurface">@color/yellow</item>
    <item name="colorOnSurface">@color/orange</item>
    <item name="colorControlActivated">@color/blue</item>
  </style>

在布局中：

<com.google.android.material.switchmaterial.SwitchMaterial
    style="@style/Widget.MaterialComponents.CompoundButton.Switch"
    ../>

使用style属性：

  <style name="CustomStyleWidget.MaterialComponents.CompoundButton.Switch"
         parent="Widget.MaterialComponents.CompoundButton.Switch">
    <item name="useMaterialThemeColors">false</item>
    <item name="trackTint">@color/track_selector</item>
    <item name="thumbTint">@color/thumb_selector</item>
  </style>

使用thumb_selector：

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

和track_selector：

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

在布局中：

<com.google.android.material.switchmaterial.SwitchMaterial
    style="@style/CustomStyleWidget.MaterialComponents.CompoundButton.Switch"
    ../>
