【中文标题】Android在抽屉布局中膨胀导航视图给出异常【英文标题】：Android inflating a Navigation view in drawer layout giving exception 【发布时间】：2015-10-31 19:32:53 【问题描述】：我正在尝试在带有导航抽屉的 android 中实现滑动菜单。但在扩展导航视图时，它给了我一个例外。为什么我会收到此异常？
这是我的代码：
MainActivity.java
package com.works.vipul.navigationview;
import android.support.design.widget.NavigationView;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity
private Toolbar toolbar;
private NavigationView navigationView;
private DrawerLayout drawerLayout;
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar); // Attaching the layout to the toolbar object
setSupportActionBar(toolbar);
//Initializing NavigationView
navigationView = (NavigationView) findViewById(R.id.navigation_view);
//Setting Navigation View Item Selected Listener to handle the item click of the navigation menu
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener()
// This method will trigger on item Click of navigation menu
@Override
public boolean onNavigationItemSelected(MenuItem menuItem)
//Checking if the item is in checked state or not, if not make it in checked state
if (menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);
//Closing drawer on item click
drawerLayout.closeDrawers();
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId())
//Replacing the main content with ContentFragment Which is our Inbox View;
case R.id.inbox:
Toast.makeText(getApplicationContext(), "Inbox Selected", Toast.LENGTH_SHORT).show();
ContentFragment fragment = new ContentFragment();
android.support.v4.app.FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.frame, fragment);
fragmentTransaction.commit();
return true;
// For rest of the options we just show a toast on click
case R.id.starred:
Toast.makeText(getApplicationContext(), "Stared Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.sent_mail:
Toast.makeText(getApplicationContext(), "Send Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.drafts:
Toast.makeText(getApplicationContext(), "Drafts Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.allmail:
Toast.makeText(getApplicationContext(), "All Mail Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.trash:
Toast.makeText(getApplicationContext(), "Trash Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.spam:
Toast.makeText(getApplicationContext(), "Spam Selected", Toast.LENGTH_SHORT).show();
return true;
default:
Toast.makeText(getApplicationContext(), "Somethings Wrong", Toast.LENGTH_SHORT).show();
return true;
);
// Initializing Drawer Layout and ActionBarToggle
drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.openDrawer, R.string.closeDrawer)
@Override
public void onDrawerClosed(View drawerView)
// Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank
super.onDrawerClosed(drawerView);
@Override
public void onDrawerOpened(View drawerView)
// Code here will be triggered once the drawer open as we dont want anything to happen so we leave this blank
super.onDrawerOpened(drawerView);
;
//Setting the actionbarToggle to drawer layout
drawerLayout.setDrawerListener(actionBarDrawerToggle);
//calling sync state is necessay or else your hamburger icon wont show up
actionBarDrawerToggle.syncState();
@Override
public boolean onCreateOptionsMenu(Menu menu)
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return 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();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings)
return true;
return super.onOptionsItemSelected(item);
ContentFragment.java
package com.works.vipul.navigationview;
import android.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
/**

public class ContentFragment extends android.support.v4.app.Fragment
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
View v = inflater.inflate(R.layout.content_fragment,container,false);
return v;

导航视图出现异常的原因是什么？
【问题讨论】：
【参考方案1】："InflateException: Binary XML file line #28: Error inflating class android.support.design.widget.NavigationView" ，意味着它在其代码域中找不到导航视图，因此无法对其进行膨胀。
可能是您这边的参考链接错误。请检查您的 gradle 文件。 您可能需要单独的 NavigationView 库，仅包括 android 支持 v7 是不够的。或者你可以检查here
【讨论】：
我也使用过 'com.android.support:design:22.2.0 库 这是我的 gradle: dependencies compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:22.2.0'编译'de.hdodenhof:circleimageview:1.3.0' 编译'com.android.support:design:22.2.0' 【参考方案2】：它的原因
Caused by: java.lang.OutOfMemoryError
检查 de.hdodenhof.circleimageview.CircleImageView 中的位图
