飞溅屏幕内部变窄

Question

我使用了一张图像作为启动屏幕的背景，它已经根据不同的像素密度调整了大小：

hdpi-480x800mdpi-320x480xhdpi-768x1280xxhdpi-1080x1920xxxhdpi-1440x2560

splash_screen.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="@drawable/launcher"/>
</layer-list>

styles.xml

<style name="AppTheme.Launcher" parent="BaseAppTheme">
<item name="android:windowBackground">@drawable/splash_screen</item>
<item name="colorPrimaryDark">@color/grey_light</item>
</style>

它在模拟器上运行良好，但在三星Galaxy M20、A7、S9等(分辨率2340x1080，屏幕密度xhdpi(上，它看起来内部变窄了。有什么解决方案吗？

阅读关于Support different pixel densities的官方指南。

在具有不同像素的设备上提供良好的图形质量密度，您应该在app——每个密度桶一个，分辨率相应。

drawable-ldpi        //240x320
drawable-mdpi        //320x480
drawable-hdpi        //480x800
drawable-xhdpi       //720x1280
drawable-xxhdpi      //1080X1920
drawable-xxxhdpi     //1440X2560

并将其添加到您的清单中

<supports-screens
android:anyDensity="true"
android:largeScreens="true"
android:normalScreens="true"
android:resizeable="true"
android:smallScreens="true"
android:xlargeScreens="true" />
