android - 如何在 Splashscreen API 中删除我的启动画面图标周围的圆形 mask ？

Question

我有一个单一的 Activity 应用程序，我正在使用 SplashScreen API。我为我的图标使用了一个可绘制的图层列表，但它周围似乎有一个圆形框架。我试过只使用图标的 png 文件，但我仍然遇到同样的问题。
样式.xml

<style name="Theme.App.Starting" parent="Theme.SplashScreen">
        // Set the splash screen background, animated icon, and animation duration.
        <item name="windowSplashScreenBackground">@color/sailor_blue</item>

        // Use windowSplashScreenAnimatedIcon to add either a drawable or an
        // animated drawable. One of these is required.
        <item name="windowSplashScreenAnimatedIcon">@drawable/splash_screen_layer_list</item>

        // Set the theme of the Activity that directly follows your splash screen.
        <item name="postSplashScreenTheme">@style/Theme.SimpleCrypto.NoActionBar</item>
    </style>

splash_screen_layer_list.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/sailor_blue" />
    <item
        android:drawable="@drawable/simple_crypto_logo"
        android:gravity="center" />
</layer-list>

安卓 list

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

    <uses-permission android:name="android.permission.INTERNET" />

    <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/Theme.SimpleCrypto"
        android:name=".SimpleCryptoApplication">
        <activity
            android:name=".MainActivity"
            android:exported="true"
            android:label="@string/app_name"
            android:windowSoftInputMode="adjustResize"
            android:resizeableActivity="true"
            android:theme="@style/Theme.App.Starting"
            tools:targetApi="24" >
            <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>

这是我的 MainActivity 文件
MainActivity.kt

class MainActivity : AppCompatActivity() {

    private lateinit var appBarConfiguration: AppBarConfiguration
    private lateinit var binding: ActivityMainBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        // Handle the splash screen transition.
        val splashScreen = installSplashScreen()

        binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)
        setSupportActionBar(binding.appBarMain.toolbar)

        val navController = findNavController(R.id.nav_host_fragment_content_main)
        binding.navView?.let {
            appBarConfiguration = AppBarConfiguration(
                setOf(
                    R.id.nav_home, R.id.nav_converter, R.id.nav_wallet, R.id.nav_settings
                ),
                binding.drawerLayout
            )
            setupActionBarWithNavController(navController, appBarConfiguration)
            it.setupWithNavController(navController)
        }

        binding.appBarMain.contentMain.bottomNavView?.let {
            appBarConfiguration = AppBarConfiguration(
                setOf(
                    R.id.nav_home, R.id.nav_converter, R.id.nav_wallet
                )
            )
            setupActionBarWithNavController(navController, appBarConfiguration)
            it.setupWithNavController(navController)
        }

        onDestinationChangedListener()
    }

Answer 1

这并不理想，但我使用 Asset Studio 将初始屏幕图形导入为自适应图标。在 Asset Studio 中，我将图标缩小到显示的安全区域内，然后它在我的初始屏幕上看起来正确。我搜索了同样的东西，但找不到改变图标形状或大小以使其更大的方法。虽然我没有看到谷歌对此的任何明确声明，但共识似乎是目标是为所有应用程序提供一致的启动屏幕体验，因此 Android 不支持圆形掩码之外的图标。他们确实声明here但是，图标前景的 1/3 被遮盖了。
