我试图将嵌套的子片段添加到父片段中。
一切正常但是..。
首先,我的代码:
public class FragmentDatasheetWithHeader extends Fragment {
private long mRowId;
private String mSid;
@Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container, final Bundle savedInstanceState) {
final Scro
我正在尝试在项目中添加'@progress/kendo-scrollview'包。我得到了以下错误
错误:(SystemJS) XHR错误(404)加载错误: XHR错误(404)加载 at XMLHttpRequest.wrapFn () at ZoneDelegate.invokeTask () at Zone.runTask () at ZoneTask.invokeTask at invokeTask () at XMLHttpRequest.globalZoneAwareCallback ()将加载为“@progress/kendo角”-scrollview: a
我创建了一个函数,它在调用ScrollView时将它滚动到一个设置的位置(接近顶部)。我希望从react-navigation选项卡栏调用该函数。调用该函数很容易,但我很难让它从屏幕组件中与scrollRef通信。
这是我的零食:
您将在App.js中找到这个函数,当按下选项卡栏时会调用该函数:
const onTabPress = () => {

y: 0,
animated: tru
在我的mounted = useRef()和return () => mounted.current = false开始时,我尝试过使用useEffect和return () => mounted.current = false,但是我仍然收到以下错误消息:

我使用将react原生版本从0.61.0升级到0.65.0。
在对package.json文件进行更改、运行npm、清除android中的build文件夹之后,构建就会成功,应用程序将以一个错误的屏幕启动。

我正在尝试动态创建stackLayouts并将它们添加到现有的scrollView中,但得到了一个错误:
JS ERROR TypeError: scrollView.addChild is not a function. (In 'scrollView.addChild(stackLayout)', 'scrollView.addChild' is undefined)
但是,通过使用console.log,它可以看到这两种情况:
StackLayout(10) ScrollView<dates>@diary/diary-page.xml:4:7;
试图通过理解错误转储来更好地了解如何进行调试。例如,我有一个引用错误如下:

一个实现样式组件和Scroll视图的原生react应用程序正在工作,但给出了以下警告:
