本文主要是介绍Android Studio官方版DrawerLayout侧滑菜单解析，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
效果图如下
这是使用android Studio新建的一个DrawerLayout项目跑出来后的效果(没有Android Studio的盆友赶紧去下载个吧)。
生成后的代码有点混乱，稍微整理一下，那么先看布局文件
activity_main.xml:
<?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:fitssystemWindows="true" tools:openDrawer="start"> <include layout="@layout/app_bar_main" android:layout_width="match_parent" android:layout_height="match_parent" /> <android.support.design.widget.NavigationView android:id="@+id/nav_view" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="start" android:fitsSystemWindows="true" app:headerLayout="@layout/nav_header_main" app:menu="@menu/activity_main_drawer" /> </android.support.v4.widget.DrawerLayout>
如上在DrawerLayout中引用了app_bar_main.xml，在NavigationView控件中heraderLayout代表的是示例图中侧滑菜单绿色的部位，menu则表示菜单项。
app_bar_main.xml:
<?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" tools:context="com.lg.slidingmenudemo.MainActivity"> <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/AppTheme.AppBarOverlay"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" app:popupTheme="@style/AppTheme.PopupOverlay" /> </android.support.design.widget.AppBarLayout> <include layout="@layout/content_main" /> </android.support.design.widget.CoordinatorLayout>
app_bar_main.xml中可以在Toolbar中设置顶部标题，感觉引用content_main.xml麻烦的话可以直接在里边写布局，删掉content_main.xml即可。
MainActivity:
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); //控制侧滑菜单 DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); ActionBarDrawerToggle toggle = new ActionBarDrawerToggle( this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); drawer.setDrawerListener(toggle); toggle.syncState(); //设定NavigationView菜单的选择事件 NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); navigationView.setNavigationItemSelectedListener(this); } //后退键 @Override public void onBackPressed() { DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); if (drawer.isDrawerOpen(GravityCompat.START)) { drawer.closeDrawer(GravityCompat.START); } else { super.onBackPressed(); } } @SuppressWarnings("StatementWithEmptyBody") @Override public boolean onNavigationItemSelected(MenuItem item) { int id = item.getItemId(); if (id == R.id.nav_camera) { } else if (id == R.id.nav_gallery) { } else if (id == R.id.nav_slideshow) { } else if (id == R.id.nav_manage) { } else if (id == R.id.nav_share) { } else if (id == R.id.nav_send) { } //关闭侧滑菜单 DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); drawer.closeDrawer(GravityCompat.START); return true; }
}自己也可以自定义侧滑菜单的menu
<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <group android:checkableBehavior="single"> <item android:id="@+id/nav_camera" android:icon="@drawable/ic_menu_camera" android:title="Import" /> <item android:id="@+id/nav_gallery" android:icon="@drawable/ic_menu_gallery" android:title="Gallery" /> <item android:id="@+id/nav_slideshow" android:icon="@drawable/ic_menu_slideshow" android:title="Slideshow" /> <item android:id="@+id/nav_manage" android:icon="@drawable/ic_menu_manage" android:title="Tools" /> </group> <item android:title="Communicate"> <menu> <item android:id="@+id/nav_share" android:icon="@drawable/ic_menu_share" android:title="Share" /> <item android:id="@+id/nav_send" android:icon="@drawable/ic_menu_send" android:title="Send" /> </menu> </item> </menu>
item中的icon为菜单项图标资源ID，title则是菜单项标题(菜单项显示的文本)，可以根据需求自定义
