Question

我正在尝试BottomSheetDialogFragment建立一个模态底页，但正如您在屏幕截图中看到的那样，它不是在导航栏后面滑动，而是在它的前面。这是向上滑动的方向。当它完全启动时，它位于导航栏上方。但它出现时看起来很难看。

知道如何解决这个问题吗？

BottomSheet类代码：

public class ExampleBottomSheetDialog extends BottomSheetDialogFragment {
private BottomSheetListener mListener;

public interface BottomSheetListener {
    void onButton1Clicked();
    void onButton2Clicked();
}

@Override
public void onAttach(Context context) {
    super.onAttach(context);

    mListener = (BottomSheetListener) context;
}

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.bottom_sheet_layout, container);

    Button button1 = v.findViewById(R.id.button1);
    Button button2 = v.findViewById(R.id.button2);

    button1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mListener.onButton1Clicked();
            dismiss();
        }
    });

    button2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mListener.onButton2Clicked();
            dismiss();
        }
    });

    return v;
}
}

在MainActivity中打开BottomSheet：

Button buttonOpenBottomSheet = findViewById(R.id.button_open_bottom_sheet);
    buttonOpenBottomSheet.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            ExampleBottomSheetDialog bottomSheet = new ExampleBottomSheetDialog();
            bottomSheet.show(getSupportFragmentManager(), "exampleBottomSheet");
        }
    });

Modal BottomSheet面向导航栏
