在Nexus设备上发出底部对话框问题

Question

这是一个问题。我创建了一个从下到上显示的对话框，并保持在屏幕的底部。定制aosp或LG股票roms是可以的，但在Nexus设备上，它在没有对话框内容的地方显示奇怪的人工制品。

一些代码：

public class BottomDialog extends DialogFragment implements MiniFragmentsCallback {

    public enum DialogType {SHIPPING, BILLING}

    private static final String DIALOG_TYPE = "dialog_type";

    private DialogType dialogType;
    @Setter
    private DataListener dataListener;

    public static BottomDialog newInstance(DialogType type, DataListener listener) {
        BottomDialog dialog = new BottomDialog();
        Bundle b = new Bundle();
        b.putSerializable(DIALOG_TYPE, type);
        dialog.setArguments(b);
        dialog.setDataListener(listener);
        return dialog;
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        return dialog;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setStyle(DialogFragment.STYLE_NORMAL, R.style.FullScreenDialog);
    }

    @Override
    public void onStart() {
        super.onStart();
        Dialog dialog = getDialog();
        if (dialog != null) {
            Window window = dialog.getWindow();
            if (window != null) {
                window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
                window.setLayout(WindowManager.LayoutParams.MATCH_PARENT,
                        WindowManager.LayoutParams.MATCH_PARENT);
            }
        }
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        Window window = getDialog().getWindow();
        WindowManager.LayoutParams wl = window.getAttributes();
        wl.x = 0;
        wl.y = getActivity().getWindowManager().getDefaultDisplay().getHeight();
        wl.width = ViewGroup.LayoutParams.MATCH_PARENT;
        wl.height = ViewGroup.LayoutParams.WRAP_CONTENT;
        return View.inflate(getActivity(), R.layout.bottom_dialog_layout, container);
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        getChildFragmentManager().beginTransaction()
                .replace(R.id.container, getDialogType()).commit();
    }
}

风格：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    android:orientation="vertical"
    android:paddingTop="56dp">

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal" />
</LinearLayout>

主题：

<style name="FullScreenDialog">
    <item name="android:windowAnimationStyle">@style/DialogAnimationStyle</item>
    <item name="android:windowTranslucentStatus" tools:targetApi="kitkat">true</item>
</style>
