Nativescript Vue Android 键盘覆盖 TextView 或键盘覆盖操作栏

Question

在用户可以发送文本的 NativeScript Vue 类聊天应用程序中打开键盘时，页面内容会覆盖 ActionBar。如果用户关闭应用程序并再次打开它，键盘输入会覆盖 TextView 组件。

我期待有类似“Fb Messenger 聊天”行为的结果：打开键盘时聊天向上滚动，但 ActionBar 和 TextField 组件中的“标题”保持固定在那里。 The actual result can be also seen from the attached image.

为了解决这个问题，我已经尝试过： "Stop keyboard overlay when interacting with TextField in a NativeScript application"

Template Flow:

ScrollView
  > StackLayout
    > GridLayout
      > SomeElement
    > GridLayout
      > TextField

我也尝试过（来自同一指南）

Android Soft Input Mode:

    android:windowSoftInputMode="stateHidden | adjustPan">

这是我的代码：

                    </StackLayout>
            </GridLayout>
    </StackLayout>
</ScrollView>
</Page>

还补充道：

import * as app from "application"
export default {
    created() {
        var window = app.android.startActivity.getWindow();
            window.setSoftInputMode(android.view.WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

但它不起作用，因为使用 ScrollView 我将所有content of the page resized（附加屏幕截图）放在一行中，或者仍然与我使用 DockLayout 时的结果相同。

I'm also attaching the difference of code between the one I wrote and the changes I made.

我遇到过这种问题，这里有一些解决方法，你可以试试，希望对你有帮助

首先，您将所有列表包装在<page> 中，它支持在页面加载后发出的loaded 事件，此时您可以获得一个事件数据，即您的Page 对象，它是可观察的数据，所以它有点帮助您的页面在软键盘出现时收听视图变化。

获得Page 后，您可以检查它是否为android 并将setFitsSystemWindows 设置为true

我放了一些代码给你试试：

   <template>
      <Page @loaded="pageLoaded">
      <ActionBar title="HHHH" class="action-bar header">
        <StackLayout orientation="horizontal" height="38" alignItems="left"
            class="actionBarContainer">
            <StackLayout class="HLeft" style="margin-top:10;" @tap="$navigateBack">
                <Label :text="back" style="font-size:27;color:#fff;"
                    class="font-awesome" />
            </StackLayout>
            <StackLayout class="HMidEdited" alignItems="left">
                <Label textWrap="true" class = "action-bar-title" :text="chatRoom.chatroomName" paddingTop = "7.5%" color="white" id="searchField"></Label>

还有这个

import { EventData } from "tns-core-modules/data/observable";
import { Page } from "tns-core-modules/ui/page";

export default {
    methods: {
      pageLoaded(args: EventData) {
       let page = <Page>args.object;
       if (page.android) {
         page.android.setFitsSystemWindows(true);
       }
     },
