Question

如图所示DialogFragment除了按钮之外全是白色。我尝试了各种布局parrams和ConstraintLayout设置，但白色背景感觉就像是一个z次序，

请指教

这就是ANdroid Studio布局编辑器的样子

我的xml：

更新
这是DialogFragment

public class GooglePlaceDetailsDialogFragment extends DialogFragment {

    private View mRootView;
    private BasePlace place;
    private Unbinder unbinder;
    RequestResponse requestResponse;
    private PlaceDetails placeDetails;

    public interface ShowPlaceListener {
        void onShowPlace(BasePlace item);
    }

    private ShowPlaceListener mShowPlaceListener;

    public static GooglePlaceDetailsDialogFragment newInstance(BasePlace item) {
        GooglePlaceDetailsDialogFragment fragment = new GooglePlaceDetailsDialogFragment();
        fragment.setPlace(item);
        return fragment;
    }

    // Called to do initial creation of a fragment.  This is called after onAttach and before onCreateView
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        try {
            mShowPlaceListener = (ShowPlaceListener) getTargetFragment();
        } catch (ClassCastException e) {
            throw new ClassCastException("Calling fragment must implement Callback ShowPlaceListener");
        }
    }

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

        ImageView imageViewStreet = mRootView.findViewById(R.id.imageView_street);
        // Just unpack the details to make it smoother
        this.requestResponse = place.requestResponse;
        this.placeDetails = place.requestResponse.placeDetails;
        unbinder = ButterKnife.bind(this, mRootView);
        getDialog().setTitle("lkjkjlkj ");
        if (placeDetails.url.equals("")) {
            if (LogManager.isDebugable()) {
                Picasso.with(getActivity()).setIndicatorsEnabled(true);
            }
            Picasso.with(getActivity())
                    .load(R.drawable.anon_user_48dp)
                    .transform(new CircleTransformation())
                    .into(imageViewStreet);

        } else {
            if (LogManager.isDebugable()) {
                Picasso.with(getActivity()).setIndicatorsEnabled(true);
            }
            Picasso.with(getActivity())
                    .load(placeDetails.url)
                    .transform(new CircleTransformation())
                    .into(imageViewStreet);
        }
        return mRootView;
    }

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

    }

    @Override
    public void onResume() {
        super.onResume();
    }

    @OnClick(R.id.btn_place_dialog_ok)
    public void onSearchClicked() {
        if (mShowPlaceListener != null) {
            mShowPlaceListener.onShowPlace(place);
        }
        dismiss();
    }

    @OnClick(R.id.btn_place_dialog_cancel)
    public void onCancelClicked() {
        dismiss();
    }

    private void setPlace(BasePlace place) {
        this.place = place;
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        unbinder.unbind();
    }
}

这是创作

 GooglePlaceDetailsDialogFragment dialog = GooglePlaceDetailsDialogFragment.newInstance(item);
            dialog.setTargetFragment(this, 0);
            DialogUtils.showDialogFragment(getFragmentManager(), dialog);

的Util ..

public class DialogUtils {

    private static String showDialogFragment(FragmentManager fragmentManager, DialogFragment dialogFragment,
                                             String fragmentTag, boolean onlyIfNotDuplicate) {

        // If only showing non duplicates dialogs, make sure the fragment isn't already in the manager
        boolean doesFragmentExist = fragmentManager.findFragmentByTag(fragmentTag) != null;
        if (!(onlyIfNotDuplicate && doesFragmentExist)) {
            dialogFragment.show(fragmentManager, fragmentTag);
        }

        return fragmentTag;
    }

    public static String showDialogFragment(FragmentManager fragmentManager, DialogFragment dialogFragment,
                                            boolean onlyIfNotDuplicate) {
        return showDialogFragment(fragmentManager, dialogFragment, generateFragmentTag(dialogFragment), onlyIfNotDuplicate);
    }

    private static String showDialogFragment(FragmentManager fragmentManager, DialogFragment dialogFragment,
                                             String fragmentTag) {
        return showDialogFragment(fragmentManager, dialogFragment, fragmentTag, true);
    }

    public static String showDialogFragment(FragmentManager fragmentManager, DialogFragment dialogFragment) {
        return showDialogFragment(fragmentManager, dialogFragment, generateFragmentTag(dialogFragment));
    }

    private static String generateFragmentTag(Fragment fragment) {
        return fragment.getClass().getName();
    }
}

Answer 1

当我用app替换srcCompat:src=时：srcCompat =`图片显示，奇怪AS没有抱怨这个错误

DialogFragment只显示按钮，即使布局有更多
