如何在android Studio中使用AppCompat类更改通知栏的颜色？

Question

<?xml version="1.0" encoding="utf-8" ?>
<resources>
  <style name="MyTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
    !-- All customizations that are NOT specific to a particular API-level can go here. -->
    <item name="windowNoTitle">true</item>
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">@color/primary</item>
    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/primary_dark</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. -->
     <item name="android:textColorPrimary">@color/primary_text</item>
     <item name="android:textColorSecondary">@color/secondary_text</item>

  </style>

  <!-- Application theme. -->
  <style name="MyTheme" parent="MyTheme.Base">
  </style>

  <style name="MyTheme.ToolBar" parent="MyTheme.Base">
    <item name="android:textColorPrimary">@android:color/white</item>
    <item name="android:textColorSecondary">@android:color/white</item>
  </style>

  <style name="MyTheme.NavMenu" parent="MyTheme.Base">
    <item name="android:textColorPrimary">@color/gray</item>
  </style>

  <style name="MyTheme.RightMenu" parent="MyTheme.Base">
    <item name="android:textColorPrimary">@color/black</item>
  </style>
</resources>

<?xml version="1.0" encoding="UTF-8" ?>
<resources>
    <style name="MyTheme" parent="MyTheme.Base">
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@color/primary_dark</item>
        <item name="android:windowContentTransitions">true</item>
        <item name="android:windowAllowEnterTransitionOverlap">true</item>
        <item name="android:windowAllowReturnTransitionOverlap">true</item>
        <item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
        <item name="android:windowSharedElementExitTransition">@android:transition/move</item>
    </style>
</resources>

这是我的颜色文件：

<resources>
  <color name="primary">#3F51B5</color>
  <color name="primary_dark">#303F9F</color>
  <color name="primary_light">#C5CAE9</color>
  <color name="accent">#FFC107</color>
  <color name="primary_text">#212121</color>
  <color name="secondary_text">#727272</color>
  <color name="icons">#FFFFFF</color>
  <color name="divider">#B6B6B6</color>
</resources>

我的样式有什么问题，为什么不改变状态栏的颜色？？

Answer 1

状态栏颜色可以通过colorPrimaryDark设置，

在您的值-v21/styles.xml中添加

<resources>
<style name="AppTheme" parent="AppTheme.Base">
    <item name="android:colorPrimaryDark">@color/colorPrimary</item>
<item name="android:colorPrimaryDark">@color/colorPrimayDark</item>
</style></resources>
