android - 底部片断内存泄漏

问题描述

我正在使用leakcanary，它说你的底部片断正在泄漏。但我看不出问题出在哪里。

我怎样才能解决这个泄漏？

public class TokensExplainedFragment extends BottomSheetDialogFragment implements HasSupportFragmentInjector {

    private static final String TAG = "TokensExplainedFragment";
    private View mainView;

    @Inject
    DispatchingAndroidInjector<Fragment> childFragmentInjector;

    @Inject
    SessionManager sessionManager;

    @Inject
    ViewModelProviderFactory providerFactory;

    public TokensExplainedFragment() {
    }

    @Override
    public void onAttach(Context context) {
        AndroidSupportInjection.inject(this);
        super.onAttach(context);
    }

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        mainView = inflater.inflate(R.layout.fragment_tokens_explained, container, false);
        return mainView;
    }

    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
    }

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


        dialog.setOnShowListener(new DialogInterface.OnShowListener() {
            @Override
            public void onShow(DialogInterface dialog) {
                BottomSheetDialog d = (BottomSheetDialog) dialog;

                FrameLayout bottomSheet = (FrameLayout) d.findViewById(com.google.android.material.R.id.design_bottom_sheet);
                BottomSheetBehavior.from(bottomSheet).setState(BottomSheetBehavior.STATE_EXPANDED);
            }
        });

        return dialog;
    }

    @Override
    public AndroidInjector<Fragment> supportFragmentInjector() {
        return childFragmentInjector;
    }
}

这就是我开始的方式：

TokensExplainedFragment bottomSheetFragment = new TokensExplainedFragment();
bottomSheetFragment.show(getActivity().getSupportFragmentManager(), bottomSheetFragment.getTag());

泄漏痕迹：

getSupportFragmentManager并且getFragmentManager都是顶级 Activity 的片段管理器。用于管理片段级别内的片段使用getChildFragmentManager

bottomSheetFragment.show(getChildFragmentManager(), bottomSheetFragment.getTag());
