颤振启动画面
Flutter Spash Screen
android:src="@drawable/grouptop" />
如何自定义启动画面图像的图像大小。我知道通过图像编辑设置它的像素大小。
但是有什么方法可以自定义尺寸(长度,宽度)?
在 drawable 文件夹中像这样制作启动器背景
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@android:color/white" />
<item
android:width="200dp"
android:height="100dp"
android:gravity="center"
android:drawable="@drawable/splash">
</item>
</layer-list>
使用这个style.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>
<item name="android:windowDisablePreview">true</item>
</style>
</resources>
在清单文件中定义
<activity
android:name=".MainActivity"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
android:hardwareAccelerated="true"
android:launchMode="singleTop"
android:theme="@style/LaunchTheme"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
