Android(安卓)之NavigationView&Toolbar&DrawerLayout

gradle

apply plugin: 'com.android.application'android {    compileSdkVersion 26    buildToolsVersion "26.0.0"    defaultConfig {        applicationId "com.example.jony.aircondemo1"        minSdkVersion 15        targetSdkVersion 26        versionCode 1        versionName "1.0"        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }}dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {        exclude group: 'com.android.support', module: 'support-annotations'    })    compile 'com.android.support:appcompat-v7:26.+'    compile 'com.android.support.constraint:constraint-layout:1.0.2'    testCompile 'junit:junit:4.12'    compile 'com.android.support:design:26.+'}

注：包的版本需要注意，design版本需要高于appcompat版本
header_layout.xml

<?xml version="1.0" encoding="utf-8"?>

两个menu文件
toolbar.xml

<?xml version="1.0" encoding="utf-8"?>

nav_menu.xml

<?xml version="1.0" encoding="utf-8"?>

注：需要在主题样式中去掉系统的ActionBar
styles.xml

main界面布局

<?xml version="1.0" encoding="utf-8"?>
