底板景观问题

在横向模式下显示底部对话框时,我的行为有误.问题发生在24. +版本的设计库中.根据下图,底片仅在横向上无法正确显示.我正在使用BottomSheetDialog类,我正在按照本教程:http://www.skholingua.com/blog/bottom-sheet-android,在我发布的应用程序中也会出现问题.

我测试了25. +版本,问题没有解决.

错误在横向24,25 +库中

23. + Library中的相同示例

    //For your bottom sheet to be displayable, you need to create a BottomSheetBehavior.
    //This is created by getting a reference to the container view and calling BottomSheetBehavior.from() on that container.
    mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);

这是一个解决方法.(注意:此代码在活动中)

View sheetView;//class level variable

private void setUpBottomSheetDialog() {

    bottomSheetDialog = new BottomSheetDialog(this);

    LayoutInflater inflater = LayoutInflater.from(this);
     sheetView = inflater.inflate(R.layout.bottom_sheet_image_source, (ViewGroup) this.getWindow().getDecorView().getRootView(), false);

    bottomSheetDialog.setContentView(sheetView);

    BottomSheetBehavior mBehavior = BottomSheetBehavior.from((View) sheetView.getParent());

    bottomSheetDialog.setOnShowListener(dialogInterface -> {
        mBehavior.setPeekHeight(sheetView.getHeight());//get the height dynamically
    });
}

Google员工已按预期完成了此操作，这是一种解决方法

屏幕高度比例有一个不可思议的常数，似乎是min（actualwidth，themewidth），这显然不适用于手机环境，因此将其覆盖更大的值

My personal choice to solve this problem is, after onCreateView, you already have the main view of the BottomSheetDialogFragment

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    mainLayout = inflater.inflate(R.layout.fragment_auction_bottom_sheet_dialog, container, false);
    return mainLayout;
}

And the onStart will be executed after you have the View created, so you can play with the behaviour:

@Override
public void onStart() {
    super.onStart();
    //this expands the bottom sheet even after a config change
    bottomSheetBehavior = BottomSheetBehavior.from((View) mainLayout.getParent());
    bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
}

Then you will always have the Bottom Sheet expanded
