我在Flutter中包含了我的android应用程序的启动图像。但是,此图像太模糊或太大。当我在硬盘上查看图像时,图像很清晰。如何保持图像清晰?
/ res / drawable / launch_background.xml:
<?xml version="1.0" encoding="utf-8"?>
<!-- Modify this file to customize your launch splash screen -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/background" />
<item>
<bitmap
android:gravity="center"
android:src="@drawable/icon_transparent_256" />
</item>
</layer-list>
/ res / values / styles.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
<!-- Show a splash screen on the activity. Automatically removed when
Flutter draws its first frame -->
<item name="android:windowBackground">@drawable/launch_background</item>
</style>
</resources>
当前结果:screenshot
实际图像:logo
[正如@Michael Dougan指出的,图像尺寸太小,最好将图像保存为不同的尺寸(例如/res/drawable/
),而不是将启动图像的一个版本保存在/res/mipmap-xxxhdpi
中]]
