Question

使用constrainLayout时支持不同屏幕尺寸的最佳方法是什么？

问题：

当我将设备更改为屏幕尺寸小于4.7的任何设备时，底部的按钮往往低于屏幕的下边缘。我已经固定按钮，我认为所有视图都将是缩小以适应其余部分。

我的代码：

Answer 1

我认为所有观点都会缩小以适应其他观点。

没有。你必须设计它<IfModule mod_rewrite.c> RewriteEngine On RewriteRule ^$ index [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 [L] </IfModule>。这不仅仅针对Dim HTMLDoc As HTMLDocument Dim MyBrowser As InternetExplorer Sub MyGmail() Dim MyHTML_Element As IHTMLElement Dim MyURL As String On Error GoTo Err_Clear MyURL = "https://www.gmail.com" Set MyBrowser = New InternetExplorer MyBrowser.Silent = True MyBrowser.navigate MyURL MyBrowser.Visible = True Do Loop Until MyBrowser.readyState = READYSTATE_COMPLETE Set HTMLDoc = MyBrowser.document HTMLDoc.all.identifierId.Value = "testaddress@gmail.com" '''Enter your email idhere '''this where I'm stuck, I can't figure out how to '''select for the Next button on GMAIL! Err_Clear: If Err <> 0 Then Err.Clear Resume Next End If End Sub，而是supports a certain minimum screen size或任何其他布局。

请参阅supporting different screen sizes。

在您的情况下，您可以使用ScrollView，以便内容在超出屏幕大小时滚动。

Answer 2

每当遇到此时，我都将ConstraintLayout包裹在ScrollView中。大多数设计都考虑到了一种屏幕尺寸，我认为您的最小屏幕尺寸不必这么大。

希望这会有所帮助。
