谢谢,
当我在 xCode 中存档我的 iOS 应用程序以上传到 Apple 应用程序商店时,它停止获取正确的版本号和内部版本号:
我的 pubspec.yaml 有正确的数字:
version: 1.0.9+11

它在 xCode 中看起来是正确的,但一旦存档就不行了:
如您所知,我们可以windowLightStatusBar
通过以下代码设置from xml.

我需要通过编程方式将此属性true更改为false或false更改为true.有没有办法实现它?
我使用的是1.14.2版本的 go。我试图加我的项目go.mod
部署Heroku的使用go mod init <dependecyname>
。之后,我尝试go run main.go

我试图将上边距设置为我的顶部元素(这是scrollview的第一项).它并没有适用于所有设备.
此外,我试图将所有matarialedittext更改为本机edittext.那仍然不起作用:/
谢谢,

Run Code Online (Sandbox Code Playgroud) 我有一个edittext
in 片段 A,用于类别列表中的静态搜索。当我用片段 B 替换片段 A 并单击后退按钮时,edittext
仍然显示我在替换片段之前编写的内容。这是我尝试过的 FragmentAoncreateview
和onactivitycreated
. 但这不起作用(我想在调用edit text
时将值设置为空字符串):popbackstack
if (customTextWatcher == null)
{
customTextWatcher = new CustomTextWatcher();
searchET.addTextChangedListener(customTextWatcher);
}
else {
searchET.removeTextChangedListener(customTextWatcher);

我想实现设置文本宽度和高度其父尺寸。这是我尝试过的,但它不起作用:
