在支持库中使用BottomSheet时如何调暗背景?

问题描述

如何像显示背景一样将背景变暗这里?

How can the background be dimmed just like it is shown here?

我通常使用CoordinatorLayout和BottomSheetBehavior对其进行设置.

I've set it up normally using the CoordinatorLayout and the BottomSheetBehavior.

推荐答案

这将仅显示一个底页.

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);
    }
}

要像平常一样直接调用close()来关闭对话框.

To close the dialog simply as normal call close().
