如何更改SwitchCompat的轨道颜色 [英] How to change the track color of a SwitchCompat

问题描述

我使用下面的链接继续改变SwitchCompat的颜色尝试：

如何改变的SwitchCompat <颜色/ P>

注意低constrast在我的开关：

但改变所有相关的颜色值后SwitchCompat的音轨（亮灰色）保持不变。我不想改变除了颜色的外观。拇指是粉红色的，和我想要的轨道有一定的反差。我错过在我的styles.xml定义值？

我想这些值（随机非白两种颜色）：

 ＆LT;样式名称=AppTheme父=Theme.AppCompat.Light.NoActionBar＆GT;
    ＆LT;项目名称=colorPrimary＆GT; @色/第一＆LT; /项目＆GT;
    ＆LT;项目名称=colorPrimaryDark＆GT; @色/秒＆LT; /项目＆GT;
    ＆LT;项目名称=colorAccent＆GT; @色/第三＆LT; /项目＆GT;
   ...
    ＆LT;项目名称=colorControlActivated＆GT; @色/第一＆LT; /项目＆GT;
    ＆LT;项目名称=colorControlHighlight＆GT; @色/第一＆LT; /项目＆GT;
    ＆LT;项目名称=colorControlNormal＆GT; @色/秒＆LT; /项目＆GT;
    ＆LT;项目名称=colorSwitchThumbNormal＆GT; @色/秒＆LT; /项目＆GT;
    ＆LT;项目名称=colorButtonNormal＆GT; @色/秒＆LT; /项目＆GT;
...＆GT;
 

解决方案

我有同样的probrem并解决它。

 ＆LT;样式名称=AppTheme父=Theme.AppCompat.Light.NoActionBar＆GT;
   ...
   ＆LT;！ - 活动拇指颜色和放大器;活动轨迹的颜色（30％的透明度） - ＆GT;
   ＆LT;项目名称=colorControlActivated＆GT; @色彩/主题＆LT; /项目＆GT;
   ＆LT;  - ！不活跃的拇指颜色 - ＆GT;
   ＆LT;项目名称=colorSwitchThumbNormal＆GT; @色/ grey300＆LT; /项目＆GT;
   ＆LT;！ - 不活动轨迹的颜色（30％的透明度） - ＆GT;
   ＆LT;项目名称=机器人：colorForeground＆GT; @色/ grey600＆LT; /项目＆GT;
   ...
＆LT; /风格＆GT;
 

我读应用程序兼容性code和理解。

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

 私人ColorStateList getSwitchTrackColorStateList（）{
    如果（mSwitchTrackStateList == NULL）{
        最终诠释[] []状态=新的INT [3] [];
        最终诠释[]颜色=新INT [3];
        INT I = 0;

        //禁用状态
        国家[我] =新的INT [] {-​​android.R.attr.state_enabled};
        颜色[I] = getThemeAttrColor（android.R.attr.colorForeground，0.1F）;
        我++;

        国家[我] =新的INT [] {android.R.attr.state_checked};
        颜色[I] = getThemeAttrColor（R.attr.colorControlActivated，0.3f）;
        我++;

        //默认启用状态
        态[I] =新INT [0];
        颜色[I] = getThemeAttrColor（android.R.attr.colorForeground，0.3f）;
        我++;

        mSwitchTrackStateList =新ColorStateList（州，颜色）;
    }
    返回mSwitchTrackStateList;
}
 

I've tried using the following link to change the color of a SwitchCompat:

How to change the color of a SwitchCompat

Notice the low constrast in my switch:

But after changing all relevant color values the track (the brighter grey) of the SwitchCompat remains the same. I don't want to change the appearance except the color. The thumb is in pink, and I want the track to have some contrast. Did I miss to define a value in my styles.xml?

I tried these values (random non-white colors):

<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>
...>

解决方案

I had same probrem and solved it.

<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>

I read app compat code, and understand it.

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;
}
