使用支持库中的BottomSheet时如何调暗背景？

Question

背景如何变暗,就像它在这里显示的一样？

我通常使用CoordinatorLayout和设置它BottomSheetBehavior.

Answer 1

这将简单地显示一个底部工作表。

public class MyBottomSheet extends BottomSheetDialogFragment {
    private static final String TAG = "MyBottomSheet";

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

        final View view = View.inflate(getContext(), R.layout.my_custom_view, null);

        dialog.setContentView(view);
        behavior = BottomSheetBehavior.from((View) view.getParent());

        return dialog;
    }

    public void show(final FragmentActivity fragmentActivity) {
        show(fragmentActivity.getSupportFragmentManager(), TAG);
    }
}

像正常调用一样关闭对话框close()。
