先来看看效果图

当你点击菜单可以更改图标，例如点击happy，首页就会变一个笑脸，这个实现的过程超级简单

你需要使用ToolBar与DrawableLayout两个比较新的控件

首先要写三个xml布局文件，我这里的布局文件是使用了include标签嵌入的，代码如下

headbar_toolbar.xml

<?xml version="1.0" encoding="utf-8"?><android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/tbHeadBar" android:layout_width="match_parent" android:layout_height="50dp" android:background="@color/red"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:text="@string/emotion" android:textColor="@color/white" android:textSize="16sp" /></android.support.v7.widget.Toolbar>

my_drawablelayout.xml

<?xml version="1.0" encoding="utf-8"?><android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/dlMenu" android:layout_width="match_parent" android:layout_height="match_parent"> <LinearLayout android:id="@+id/llContent" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/white" android:gravity="center" android:orientation="vertical"> <ImageView android:id="@+id/ivContent" android:layout_width="100dp" android:layout_height="100dp" android:src="@drawable/angry" /> </LinearLayout> <!--android:layout_gravity="start"属性使这部分作为侧滑部分--> <!--一定要放在下面！！！关于控件的层次性如果不知道的同学去百度！哦不去谷歌--> <LinearLayout android:id="@+id/llMenu" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_gravity="start" android:background="@color/white" android:orientation="vertical"> <!--用于设置菜单项--> <ListView android:id="@+id/lvMenu" android:layout_width="match_parent" android:layout_height="match_parent" android:divider="@null" /> </LinearLayout></android.support.v4.widget.DrawerLayout>

main_activity.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.demo.usher.demo_slidingmenu.MainActivity"> <!--头部--> <include layout="@layout/headbar_toolbar" /> <!--主布局--> <include layout="@layout/my_drawablelayout" /></LinearLayout>

如何应用在java文件中【一个文件搞定】

package com.demo.usher.demo_slidingmenu;import android.os.Bundle;import android.support.v4.widget.DrawerLayout;import android.support.v7.app.ActionBarDrawerToggle;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.Toolbar;import android.view.View;import android.widget.AdapterView;import android.widget.ArrayAdapter;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.ListView;import java.util.ArrayList;import java.util.List;import butterknife.BindView;import butterknife.ButterKnife;public class MainActivity extends AppCompatActivity { @BindView(R.id.tbHeadBar) Toolbar mTbHeadBar; @BindView(R.id.llMenu) LinearLayout mLlMenu; @BindView(R.id.lvMenu) ListView mLvMenu; @BindView(R.id.ivContent) ImageView mIvContent; @BindView(R.id.dlMenu) DrawerLayout mMyDrawable; ActionBarDrawerToggle mToggle; private List<String> lvMenuList = new ArrayList<String>() {{ add("angry"); add("happy"); add("sad"); add("embarrassed"); }}; private List<Integer> imageList = new ArrayList<Integer>() {{ add(R.drawable.angry); add(R.drawable.happy); add(R.drawable.sad); add(R.drawable.embarrassed); }}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ButterKnife.bind(this); initToolBarAndDrawableLayout(); mLvMenu.setAdapter(new ArrayAdapter(this, android.R.layout.simple_expandable_list_item_1, lvMenuList)); mLvMenu.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { mIvContent.setImageResource(imageList.get(position)); mMyDrawable.closeDrawers(); } }); } private void initToolBarAndDrawableLayout() { setSupportActionBar(mTbHeadBar); getSupportActionBar().setHomeButtonEnabled(true); getSupportActionBar().setDisplayHomeAsUpEnabled(true); getSupportActionBar().setDisplayShowTitleEnabled(false); mToggle = new ActionBarDrawerToggle(this, mMyDrawable, mTbHeadBar, R.string.open, R.string.close) { @Override public void onDrawerOpened(View drawerView) { super.onDrawerOpened(drawerView); //Toast.makeText(MainActivity.this, R.string.open, Toast.LENGTH_SHORT).show(); } @Override public void onDrawerClosed(View drawerView) { super.onDrawerClosed(drawerView); //Toast.makeText(MainActivity.this, R.string.close, Toast.LENGTH_SHORT).show(); } }; mMyDrawable.addDrawerListener(mToggle); mToggle.syncState(); }}

关于butterknife注解与样式

butterknife直接在gradle文件中配置好如下【缺什么就补什么】

apply plugin: 'com.android.application'apply plugin: 'android-apt'android { compileSdkVersion 24 buildToolsVersion "24.0.2" defaultConfig { applicationId "com.demo.usher.demo_slidingmenu" minSdkVersion 15 targetSdkVersion 24 versionCode 1 versionName "1.0" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } }}buildscript { repositories { mavenCentral() } dependencies { classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8' }}dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:24.2.0' compile 'com.jakewharton:butterknife:8.4.0' apt 'com.jakewharton:butterknife-compiler:8.4.0' compile 'com.android.support:support-v4:24.2.0'}

style【关于返回键的颜色样式等在style文件中修改】

<resources> <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <item name="drawerArrowStyle">@style/AppTheme.DrawerArrowToggle</item> </style> <style name="AppTheme.DrawerArrowToggle" parent="Base.Widget.AppCompat.DrawerArrowToggle"> <item name="color">@android:color/white</item> </style></resources>

总结

其实很多时候我们在使用第三方控件的时候往往不知道背后是怎么实现的，使用原生控件可以让我们更好的理解一个交互或者说实现一个功能的原理，有利于做出性能与交互都非常优秀的APP，以上就是这篇文章的全部内容，希望对大家的工作或学习带来一定的帮助。
