Android P 启动页适配适配刘海屏

需求: app 启动页全屏，延伸到刘海屏的状态栏和底部的导航栏，操作步骤如下:

app 的 build.gradle 配置

注意 compileSdkVersion、buildToolsVersion、targetSdkVersion 都是 30

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.2"

    defaultConfig {
        applicationId "com.toys.testimmersionbar"
        minSdkVersion 21
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.3.2'
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    api 'com.gyf.barlibrary:barlibrary:2.3.0'
    implementation 'com.google.android.material:material:1.1.0-alpha05'
}

启动页 SplashActivity 代码

注意: SplashActivity 不需要 setContentView( )

class SplashActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
//        setContentView(R.layout.activity_splash3)
        supportRequestWindowFeature(Window.FEATURE_NO_TITLE)

        StatusBarCompat.setTranslucentDiff(this)
        StatusBarCompat.setNavigationBarTransparent(this)

        Handler().postDelayed({
            startActivity(Intent(this, MainActivity::class.java))
        }, 3000)
    }
}

AndroidManifest.xml 配置

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.toys.testimmersionbar">

    <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/AppTheme"
        >
        <activity android:name=".activity.MainActivity" />
        <activity
            android:name=".activity.SplashActivity3"
            android:screenOrientation="portrait"
            android:theme="@style/AppTheme.Splash">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <!-- 华为刘海屏区域使用 -->
            <meta-data
                android:name="android.notch_support"
                android:value="true" />
        </activity>
    </application>

</manifest>

styles.xml

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="AppTheme.Splash" parent="Theme.MaterialComponents.Light.NoActionBar">
        <item name="colorPrimary">@color/white</item>
        <item name="colorPrimaryDark">@color/white</item>
        <item name="colorAccent">@color/white</item>
        <item name="android:windowTranslucentStatus">false</item>
        <item name="android:windowTranslucentNavigation">true</item>
        <item name="android:windowBackground">@drawable/splash_logo_bg</item>
<!--        <item name="android:windowAnimationStyle">@style/ActivityAnimationFadeIn</item>-->
        <item name="android:windowFullscreen">false</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
    </style>

</resources>

splash_logo_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:opacity="opaque">

    <item android:drawable="@color/bg_splash" />

    <!--顶部 girl-->
    <item
        android:top="227dp">
        <bitmap
            android:gravity="top"
            android:src="@drawable/mc_forum_face234" />
    </item>

</layer-list>

splash_logo_bg.xml 的预览效果如下:
