如何在 bottomsheet 对话框片段中将 scrim 更改为不可见？

Question

我使用 bottomsheetdialogfragment 实现了 bottomsheet。但默认它具有调光效果（稀松布）。如何移除调光效果（稀松布）或将其更改为不可见，以便我可以清楚地看到其他 UI 元素。

这是我使用的布局。

fragment_bottom_sheet_queue.xml

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

BottomSheetFragment.java

public class BottomSheetFragment extends BottomSheetDialogFragment {

private BottomSheetBehavior mBehavior;

    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        BottomSheetDialog dialog = (BottomSheetDialog) super.onCreateDialog(savedInstanceState);

        View view = View.inflate(getContext(), R.layout.fragment_bottom_queue_sheet, null);
        activity = getActivity();

        dialog.setContentView(view);
        mBehavior = BottomSheetBehavior.from((View) view.getParent());
        return dialog;
    }

有暗淡效果 (SCRIM)

不调用底部sheet时

Answer 1

您可以更改 Window 标志和暗淡量来实现此效果。

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    BottomSheetDialog dialog = super.onCreateDialog(savedInstanceState);

    Window window = dialog.getWindow();
    window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
    window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
    return dialog;
}

Answer 2

现在 2021 年可以通过简单的方法更改暗淡量。只需在对话框的 window:

上使用 setDimAmount()

val dialog = BottomSheetDialog(context)
...
dialog.window?.setDimAmount(0f) // remove any dim
