安卓 8

我的styles.xml 文件是这样的

My styles.xml file look like this

<resources xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto">
<style name="DropitTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>


    <style name="MyThemeOverlay_Toolbar" parent="ThemeOverlay.MaterialComponents.Toolbar.Primary">
        <!-- color used by navigation icon and overflow icon -->
        <item name="colorOnPrimary">@color/colorPrimary</item>
    </style>

    <style name="Toolbar_text_style" parent="TextAppearance.Widget.AppCompat.Toolbar.Title">
        <!-- color used by navigation icon and overflow icon -->
        <item name="android:textSize">@dimen/textSizeHuge</item>
    </style>
</resources>

清单

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.app">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/DropitTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <meta-data
            android:name="preloaded_fonts"
            android:resource="@array/preloaded_fonts" />
    </application>

</manifest>

最后是 themes.xml

and last the themes.xml

<resources xmlns:tools="http://schemas.android.com/tools">
    <!-- Base application theme. -->
    <!-- Base application theme. -->
    <style name="Theme.Dropit" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
        <!-- Primary brand color. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryVariant">@color/colorSecondary</item>
        <item name="colorOnPrimary">@color/white</item>
        <!-- Secondary brand color. -->
        <item name="colorSecondary">@color/colorSecondary</item>
        <item name="colorSecondaryVariant">@color/colorSecondaryLight</item>
        <item name="colorOnSecondary">@color/white</item>
        <!-- Status bar color. -->
        <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
        <!-- Customize your theme here. -->
    </style>
</resources>

正如您在清单中看到的，我使用的是样式主题而不是主题主题.那么我该如何解决这个问题?

As you can see in the Manifest I'm using the styles theme not the themes theme. So how can i fix this problem?

推荐答案

我遇到了同样的问题并找到了这个解决方案.

I had the same problem and find out this solution.

val controller = requireActivity().window.insetsController
        controller?.systemBarsBehavior = BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
        controller?.hide(WindowInsets.Type.statusBars())

如果从 Activity 调用，则不需要 requireActivity().我遇到了一些问题，在某些片段上它开始重置为标准状态栏，所以我在每个 onCreate() 上调用它并修复它.

If you call it from Activity requireActivity() is not needed. I had some problems where on some fragments it started to reset to the standard status bar, so I called it on every onCreate() and it fixed it.
