android - Flutter - 当键盘出现在android上时文本字段不显示

Question

我的问题是，当我专注于文本字段时，键盘会出现，但布局不会调整大小以将其保留在视图中。这个问题只存在于 android 而不是 iOS：这里是我的意思的截图：

在android上之前和之后：

iOS 之前和之后：

这是我的课：

class PlayerSelectionPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    int itemCount = Provider.of<PlayerProvider>(context).getPlayerList.length;
    SystemChrome.setPreferredOrientations([
      DeviceOrientation.portraitUp,
    ]);
    return Scaffold(
      appBar: AppBar(
        title: Text(AppLocalizations.of(context).translate('player_selection_page_title')),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: (){
          HapticFeedback.mediumImpact();
          Navigator.push(context, MaterialPageRoute(builder: (context) => HomePage(), settings: RouteSettings(name: 'Home page')));
        },
        child: Icon(
          Icons.chevron_right,
          size: 30,
          color: Colors.white,
        ),
      ),
      body: itemCount > 0 ? ListView.builder(
          itemCount: itemCount,
          itemBuilder: (context, index) {
            return Column(
              children: [
                PlayerDismissible(index),
                Divider(
                  height: 0,
                )
              ],
            );
          }) : Container(
          padding: EdgeInsets.all(20),
          alignment: Alignment.topCenter,
          child: Text(AppLocalizations.of(context).translate('player_selection_page_empty_text'), textAlign: TextAlign.center, style: Theme.of(context).textTheme.subtitle2)
      ),
      bottomSheet: BottomPlayerBar(),
    );
  }
}

这是我的 BottomPlayerBar() ：

class BottomPlayerBar extends StatefulWidget{
  @override
  _BottomPlayerBarState createState() => _BottomPlayerBarState();
}

class _BottomPlayerBarState extends State<BottomPlayerBar> {
  String playerName;
  FocusNode myFocusNode;


  @override
  void initState() {
    super.initState();
    myFocusNode = FocusNode();
    SchedulerBinding.instance.addPostFrameCallback((_) {
      if (ModalRoute.of(context).isCurrent) {
        myFocusNode.requestFocus();
      }
    });
  }

  @override
  Widget build(BuildContext context) {
    return Container(
        height: 80, color: Theme.of(context).primaryColor,
        padding: EdgeInsets.only(top: 20, bottom: 25, left: 20, right: 70),
        child: TextField(
          focusNode: myFocusNode,
          textCapitalization: TextCapitalization.words,
          onChanged: (val) => playerName = val.trim(),
          onSubmitted: (val) {
            if (playerName != null && playerName != '') {
              Provider.of<PlayerProvider>(context, listen: false).addPlayer(playerName);
              HapticFeedback.lightImpact();
              myFocusNode.requestFocus();
            } else {
              myFocusNode.unfocus();
            }
          },
          maxLength: 19,
          autocorrect: false,
          decoration: new InputDecoration(
              counterText: "",
              border: new OutlineInputBorder(
                borderSide: BorderSide.none,
                borderRadius: const BorderRadius.all(
                  const Radius.circular(30.0),
                ),
              ),
              filled: true,
              contentPadding: EdgeInsets.symmetric(vertical: 0, horizontal: 20),
              hintStyle: GoogleFonts.rubik(color: Colors.grey[500], fontWeight: FontWeight.bold),
              hintText: AppLocalizations.of(context).translate('player_selection_page_hint'),
              fillColor: Colors.white),
        )
    );
  }

  @override
  void dispose() {
    super.dispose();
    myFocusNode.dispose();
  }
}

您可以使用 Transform Widget 包装您的 BottomPlayerBar 小部件，如下所示。

Transform.translate(
    offset: Offset(0.0, -1 * MediaQuery.of(context).viewInsets.bottom),
    child: BottomPlayerBar(),
    );
