如在此和在Android应用程序开发一个新手，我怎么能有呢？我在这里错过了什么？

Toolbar.xml

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"

    app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

MainActivity.java

package com.android.demo; 

import android.support.v4.widget.DrawerLayout; 
import android.support.v7.app.ActionBarDrawerToggle;

import android.os.Bundle; 
import android.support.v7.widget.Toolbar; 
import android.view.Menu; 
import android.view.MenuInflater; 
import android.view.MenuItem; 

public class Main extends AppCompatActivity { 

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

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

     // Drawer 
     DrawerLayout drawer = (DrawerLayout) findViewById(R.id.main); 
     ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_open, R.string.navigation_close); 
     drawer.addDrawerListener(toggle); 
     toggle.syncState(); 
    } 

    ... 
}

访问的OnDrawerSlide方法，你可以选择覆盖在ActionBarDrawerToggle类implimented的方法，示例如下所示

drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, 
      getToolbar(), R.string.open, R.string.close) { 

     @Override 
     public void onDrawerSlide(View drawerView, float slideOffset) { 
      super.onDrawerSlide(drawerView, slideOffset); 
     } 
    };
