Question

我在带有导航抽屉的Android应用程序上工作，但是当我将抽屉的代码添加到现有代码（webview和底栏）时，工具栏不会显示。抽屉有效。

这是我的代码：

MainActivity.java

package julians.de.test;

import android.content.res.Configuration;
import android.support.design.widget.CoordinatorLayout;
import android.support.v4.widget.DrawerLayout;
import android.support.v4.widget.SwipeRefreshLayout;

    private CoordinatorLayout coordinatorLayout;
    private SwipeRefreshLayout swipeContainer;

    Toolbar toolbar;

    DrawerLayout drawerLayoutgesamt;
    ActionBarDrawerToggle drawerToggle;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        toolbar = (Toolbar) findViewById(R.id.toolbar1);
        setSupportActionBar(toolbar);

        coordinatorLayout = (CoordinatorLayout) findViewById(R.id.three_buttons_activity);
        swipeContainer = (SwipeRefreshLayout) findViewById(R.id.swipeContainer);

        drawerLayoutgesamt = (DrawerLayout) findViewById(R.id.drawerlayoutgesamt);
        drawerToggle = new ActionBarDrawerToggle(MainActivity.this,drawerLayoutgesamt,R.string.auf, R.string.zu);
        drawerLayoutgesamt.setDrawerListener(drawerToggle);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        drawerToggle.syncState();

        swipeContainer.setColorSchemeResources(android.R.color.holo_blue_bright,
                android.R.color.holo_green_light,
                android.R.color.holo_orange_light,
                android.R.color.holo_red_light);


        final WebView myWebView = (WebView) findViewById(R.id.webview);
        myWebView.setWebViewClient(new WebViewClient());

        myWebView.getSettings().setUseWideViewPort(true);
        myWebView.getSettings().setBuiltInZoomControls(true);
        myWebView.getSettings().setDisplayZoomControls(true);
        myWebView.loadUrl("http://www.apple.com");

        swipeContainer.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                myWebView.reload();
                swipeContainer.setRefreshing(false);
            }
        });

        BottomBar bottomBar = BottomBar.attach(this, savedInstanceState);
        bottomBar.setItemsFromMenu(R.menu.three_buttons_menu, new OnMenuTabSelectedListener() {
            @Override
            public void onMenuItemSelected(int itemId) {
                switch (itemId) {
                    case R.id.recent_item:
                        myWebView.getSettings().setLoadWithOverviewMode(true);
                        myWebView.getSettings().setUseWideViewPort(true);
                        myWebView.getSettings().setBuiltInZoomControls(true);
                        myWebView.getSettings().setDisplayZoomControls(true);
                        myWebView.loadUrl("http://www.apple.com");
                        break;
                    case R.id.favorite_item:
                        myWebView.getSettings().setLoadWithOverviewMode(false);
                        myWebView.getSettings().setUseWideViewPort(false);
                        myWebView.getSettings().setBuiltInZoomControls(false);
                        myWebView.getSettings().setDisplayZoomControls(false);
                        myWebView.loadUrl("http://www.apple.com");
                        break;
                    case R.id.location_item:

                        break;
                }
            }
        });

        bottomBar.setActiveTabColor("#C2185B");
        bottomBar.useDarkTheme(true);


    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();



        if (drawerToggle.onOptionsItemSelected(item)) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }


    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        drawerToggle.syncState();
    }

    @Override

        super.onConfigurationChanged(newConfig);

感谢您的帮助！

Answer 1

您是否尝试过使用android studio提供的导航抽屉模板，如果是这样，请使用片段作为主要活动代替活动

Answer 2

DrawerLayout充当窗口内容的顶级容器...要使用DrawerLayout，请将主要内容视图定位为具有match_parent的宽度和高度且没有layout_gravity的第一个子视图

你应该试试这个结构

var express = require('express');
var siteRoutes = express.Router();
var path = require('path');
var passport = require(path.resolve(__dirname, '..', '..', './config/passport.js'));

/*====  /AUTH/GOOGLE  ====*/

siteRoutes.route('/auth/google') 
    .get(function(req, res){
        console.log('Google Auth triggered');
        passport.authorize('google', { scope : ['profile'] })
    });

/*====  /AUTH/GOOGLE/CALLBACK  ====*/

siteRoutes.route('/auth/google/callback') 
    .get(function(req, res){
        passport.authorize('google', {
            successRedirect : '/app',
            failureRedirect : '/login',
            failureFlash: 'Invalid Google credentials.'
        });
    });

Android App不显示工具栏
