Question

应用程序应该有一个从左侧拉出来并显示各种活动的导航抽屉，但是一旦导航栏添加到XML activity_homescreen doc，应用程序就会在启动后立即崩溃。

HomeScreen.java

package com.t99sdevelopment.centralized;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.widget.Toolbar;

public class HomeScreen extends AppCompatActivity {

    /*
    Intent intentHome = new Intent(this, HomeScreen.class);
    Intent intentAnnouncements = new Intent(this, AnnouncementsScreen.class);
    Intent intentSchedule = new Intent(this, ScheduleScreen.class);
    Intent intentCalendar = new Intent(this, CalendarScreen.class);
    Intent intentContactBook = new Intent(this, ContactBookScreen.class);
    Intent intentSportsSchedule = new Intent(this, SportsScheduleScreen.class);
    Intent intentFrontAndCentral = new Intent(this, FrontAndCentralScreen.class);
    Intent intentMap = new Intent(this, MapScreen.class);
    Intent intentAccount = new Intent(this, AccountScreen.class);
    */

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_homescreen);
        setTheme(R.style.AppTheme);
    }

    /*
    private void goToHome(View view){ startActivity(intentHome ); }
    private void goToAnnouncements(View view){ startActivity(intentAnnouncements ); }
    private void goToSchedule(View view){ startActivity(intentSchedule); }
    private void goToCalendar(View view){ startActivity(intentCalendar); }
    private void goToContactBook(View view){ startActivity(intentContactBook); }
    private void goToSportsSchedule(View view){ startActivity(intentSportsSchedule); }
    private void goToFrontAndCentral(View view){ startActivity(intentFrontAndCentral); }
    private void goToMap(View view){ startActivity(intentMap); }
    private void goToAccount(View view){ startActivity(intentAccount); }
    */
}

使用这些文件，应用程序崩溃，但如果我更改activity_homescreen.xml如下（注释掉导航视图小部件）...

除了导航抽屉没有包含/工作之外，一切正常。有没有人有这个问题，甚至更好，有谁知道如何解决它？我需要导航抽屉工作，但它似乎崩溃我的应用程序。

logcat溢出了最大字符数，所以这里是github gist。

Answer 1

肯定是你的logcat缺少一个方法的问题：

Caused by: android.view.InflateException: Couldn't resolve menu item onClick handler goToHome in class com.t99sdevelopment.centralized.HomeScreen
Caused by: java.lang.NoSuchMethodException: goToHome [interface android.view.MenuItem]

错误膨胀类android.support.design.widget.NavigationView [启动时崩溃]
