在Webview中键入键盘时如何隐藏底部导航栏

如何解决在Webview中键入键盘时如何隐藏底部导航栏

在片段之一的WebView中键入键盘时，如何隐藏底部导航栏？

这是我的片段：

    public class chatFragment extends Fragment {
        LinearLayout eLinearLayout_chat;
        WebView webView_chat;
        ProgressBar mProgressBar_chat;
        BottomNavigationView nav;
        //SwipeRefreshLayout swipeRefreshLayout_chat;
        // Firebase instance variables
        //private FirebaseAuth mFirebaseAuth;
        //private FirebaseUser mFirebaseUser;
        //private String mUsername;
        //private String mPhotoUrl;
    
    
        public chatFragment() {
            // Required empty public constructor
        }
    
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
    
        }
    
        @Override
        public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
            // Inflate the layout for this fragment
            View v = inflater.inflate(R.layout.fragment_chat,container,false);
            webView_chat = (WebView) v.findViewById(R.id.webview_chat);
            eLinearLayout_chat = (LinearLayout) v.findViewById(R.id.LinearWebView_chat);
            mProgressBar_chat = (ProgressBar) v.findViewById(R.id.progressBar_chat);
            nav = (BottomNavigationView) v.getRootView().findViewById(R.id.bottom_navigation);
            //swipeRefreshLayout_chat = (SwipeRefreshLayout) v.findViewById(R.id.swipeweb_chat);
            webView_chat.loadUrl("https://drriyadh-lab.xyz/track/");
            webView_chat.getSettings().setJavaScriptEnabled(true);
            webView_chat.getSettings().setUseWideViewPort(true);
            webView_chat.getSettings().setDomStorageEnabled(true);
            webView_chat.getSettings().setSupportZoom(false);
            webView_chat.getSettings().setAppCacheEnabled(true);
            webView_chat.getSettings().setDatabaseEnabled(true);
            webView_chat.getSettings().setAllowFileAccess(true);
            webView_chat.getSettings().setAllowContentAccess(true);
            webView_chat.getSettings().setSupportMultipleWindows(true);
            webView_chat.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
            webView_chat.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
            webView_chat.getSettings().setLoadWithOverviewMode(true);
    
    
            webView_chat.setWebViewClient(new WebViewClient() {
    
    
                @Override
                public void onPageStarted(WebView view,String url,Bitmap favicon) {
                    super.onPageStarted(view,url,favicon);
                    //mProgressBar_chat.setVisibility(View.VISIBLE);
    
                }
    
                @Override
                public void onPageFinished(WebView view,String url) {
                    super.onPageFinished(view,url);
                    mProgressBar_chat.setVisibility(View.GONE);
    
                }
    
                @Override
                public void onReceivedError(WebView view,WebResourceRequest request,WebResourceError error) {
                    super.onReceivedError(view,request,error);
                    eLinearLayout_chat.setVisibility(View.VISIBLE);
                    view.setVisibility(View.GONE);
                }
    
                @Override
                public boolean shouldOverrideUrlLoading(WebView view,String url) {
                    if (url.contains("https://www.tidio.com/powered-by-tidio/live-chat/?platform=others&project=dc71bf5k0ncictpdhdyhujy2hzf9zn7x&device=mobile&utm_source=plugin_ref&utm_medium=widget_v4&utm_campaign=plugin_ref&utm_referrer=drriyadh-lab.xyz")) {
                        Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse(url));
                        startActivity(intent);
                        return true;
                    }
                    if (url.startsWith("tel:") || url.startsWith("whatsapp:")) {
                        Intent intent = new Intent(Intent.ACTION_VIEW);
                        intent.setData(Uri.parse(url));
                        startActivity(intent);
                        return true;
                    }
                    // all the rest open in Webview // make it false to fisable button of powered by tidio (still but not work in webview) make it to false to make whatsapp link opened,make it true to disbale whatsapp link and enable powered by tidio link work but in external browser
                    return false;
                }
    
            });
    
            return v;
        }
    
    }

我尝试了很多想法，但是没有找到任何解决方案，并且底部导航位于MainActivity中，底部导航栏中有3个片段。片段之一是WebView（如上所示）。当我输入键盘时，底部的导航键会向上移动键盘。我想在输入键盘时将其隐藏。

解决方法

我已经解决了问题 首先制作View v = inflater.inflate(R.layout.fragment_track,container,false); 使其最终 像这样

final View v = inflater.inflate(R.layout.fragment_track,false);

（用您的布局名称替换布局名称） 添加

BottomNavigationView nav;

给你 片段类

之后添加

nav = (BottomNavigationView) getActivity().findViewById(R.id.bottom_navigation);

to your `public class (fragment name) extends Fragment`


 public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
}

在activity_main中用底部导航ID替换ID

这一切之后 添加

v.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                Rect r = new Rect();
                //r will be populated with the coordinates of your view that area still visible.
                v.getWindowVisibleDisplayFrame(r);
                int orgnal = Resources.getSystem().getDisplayMetrics().heightPixels;
                int heightDiff = orgnal - v.getHeight();
                if (heightDiff > 500) { // if more than 100 pixels,its probably a keyboard...
                    nav.setVisibility(View.GONE);
                } else {

                    nav.setVisibility(View.VISIBLE);
                }
            }
        });

之后

final View v = inflater.inflate(R.layout.your layout name,false);

并且在return v;

之前

它应该工作 谢谢大家
