一丶概述

Android侧滑效果实现有很多种，这里先说说，Android系统5.0后自带的DrawerLayout + NavigationView。

二丶效果图

三丶看代码

DrawerLayout + NavigationView  xml布局

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/blue_bg">

            <com.example.jinboy.codertodeveloperbytcler.java_demo.appdemo.ui.view.CircleImageView
                android:id="@+id/iv_mine_avatar"
                android:layout_width="50dp"
                android:layout_height="50dp"
                android:layout_marginTop="5dp"
                android:layout_marginBottom="5dp"
                android:layout_below="@+id/title_bar"
                android:layout_marginStart="10dp"
                android:src="@drawable/mine_me"/>
            
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerInParent="true"
                android:text="CSDN 博客"
                android:textColor="@android:color/black"
                android:textSize="20sp"
                android:textStyle="bold" />

        </RelativeLayout>
        
    </LinearLayout>

    <android.support.design.widget.NavigationView
        android:id="@+id/navigationView"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header"
        app:menu="@menu/activity_main_drawer" />

</android.support.v4.widget.DrawerLayout>

NavigationView里的headerLayout 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/bg_evenings"
    android:orientation="vertical">
    
    <com.example.jinboy.codertodeveloperbytcler.java_demo.appdemo.ui.view.CircleImageView
        android:id="@+id/iv_mine_avatar"
        android:layout_width="70dp"
        android:layout_height="70dp"
        android:layout_below="@+id/title_bar"
        android:layout_centerHorizontal="true"
        android:layout_marginStart="10dp"
        android:layout_marginTop="50dp"
        android:src="@drawable/mine_me"/>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="20dp"
        android:layout_marginEnd="10dp"
        android:layout_marginStart="10dp"
        android:layout_marginTop="20dp"
        android:text="我的博客地址：\nhttp://blog.csdn.net/dt235201314"
        android:textColor="@color/white"
        android:textSize="15sp"
        android:textStyle="bold" />

</LinearLayout>

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_csdn"
            android:icon="@mipmap/mine_about_icon"
            android:title="CSDN" />
        <item
            android:id="@+id/nav_jianshu"
            android:icon="@mipmap/mine_about_icon"
            android:title="简书" />
    </group>

</menu>

分别对应

属性设置注意点：

1.android:layout_gravity="left"或者“star”表示从左边弹出，这里跟后面java代码关闭相关

drawerLayout.closeDrawer(GravityCompat.START);

2.app:itemIconTint="@color/blue" 设置菜单选项图片颜色，不写默认为无色（灰色），如需要现实为图片原本颜色java代码设置

navigationView.setItemIconTintList(null);

Activity java代码

public class MyCsdnActivity extends Activity implements NavigationView.OnNavigationItemSelectedListener {

    private DrawerLayout drawerLayout;
    private CircleImageView circleImageView;

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

    private void initView() {
        drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        circleImageView = (CircleImageView) findViewById(R.id.iv_mine_avatar);
        NavigationView navigationView = (NavigationView) findViewById(R.id.navigationView);
        navigationView.setNavigationItemSelectedListener(this);
        navigationView.setItemIconTintList(null);
        circleImageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                drawerLayout.openDrawer(GravityCompat.START);
            }
        });
    }

    /**
     * 菜单点击响应函数
     *
     * @param item 菜单
     * @return boolean
     */
    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
        drawerLayout.closeDrawer(GravityCompat.START);
        switch (item.getItemId()) {
            case R.id.nav_csdn:
                WebViewActivity.startWebViewActivity(this,"http://my.csdn.net/dt235201314");
                break;
            case R.id.nav_jianshu:
                WebViewActivity.startWebViewActivity(this,"http://www.jianshu.com/u/905c7de5ae83");
                break;
            default:
        }
        return false;
    }

    /**
     * 重写返回键响应函数
     */
    @Override
    public void onBackPressed() {
        if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
            drawerLayout.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }
    }
}

3.NavigationView头部布局的id

NavigationView navigationView = (NavigationView) findViewById(R.id.navigationView);
View headerView = navigationView.getHeaderView(0);
tv_name = (TextView) headerView.findViewById(R.id.tv_name);
tv_originalArticleNumber = (TextView) headerView.findViewById(R.id.tv_originalArticleNumber);
tv_visitNumber = (TextView) headerView.findViewById(R.id.tv_visitNumber);
