如何修复On resume方法不会在Webview中被调用为Fragment导航抽屉中的片段

Question

我有一个webview作为片段，它在我的片段导航抽屉中扩展片段类。我想检测这个片段的背压。 下面是用于检测片段

上的背压的代码

getView().setFocusableInTouchMode(true);
        getView().requestFocus();
        getView().setOnKeyListener(new View.OnKeyListener() {
            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event) {
                if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK){
                    // handle back button

                 getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.container,new MyFragment()).commit();
                    return true;
                }
                return false;
            }
        });

在我的webview中，每次按下按钮

时都不会调用此方法

public class WebViewFragment extends Fragment {
    static View view;
    private WebView webView;
    private String url;
    static int count = 0;
    LinearLayout llayout;
    MyProgressDialog progressDialog;


    public WebViewFragment() {

    }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
        if (view != null) {
            ViewGroup parent = (ViewGroup) view.getParent();
            if (parent != null)
                parent.removeView(view);
        }

        try {
            ((AdvancedActivity) getActivity()).getSupportActionBar().hide();
            view = inflater.inflate(R.layout.activity_play_lesson, container, false);
            //Get webview
            webView = (WebView) view.findViewById(R.id.web_view_play_lesson);

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                webView.setWebContentsDebuggingEnabled(true);
            }
            llayout = (LinearLayout) view.findViewById(R.id.linearLayout);







            getActivity().getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
            getActivity().getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
            url = getResources().getString(R.string.myurl);

            url = "http://myurl//88";
            System.out.println("url for myplay is "+url);
            startWebView(url);

        } catch (InflateException e) {

        }
        return view;
    }
