1、首先导包
- compile 'com.android.support:design:26.1.0'
首先在主布局文件中使用DrawerLayout作为外包装，里面包含一个主页面和侧滑的菜单页面，而侧滑菜单页面用NavigationView实现，drawerLayout中包含了主页面和侧滑的菜单页面：

import android.support.design.widget.NavigationView;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.AppCompatActivity;
import android.view.MenuItem;
import android.view.View;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
private DrawerLayout drawerLayout;
private NavigationView navigationView;

LinearLayout contentView ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
drawerLayout = (DrawerLayout) findViewById(R.id.activity_na);
navigationView = (NavigationView) findViewById(R.id.nav);
menu= (ImageView) findViewById(R.id.main_menu);
View headerView = navigationView.getHeaderView(0);//获取头布局
menu.setOnClickListener(this);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {

//item.setChecked(true);
Toast.makeText(MainActivity.this,item.getTitle().toString(),Toast.LENGTH_SHORT).show();

return true;
}
});
//为DrawerLayout控件添加监听器
drawerLayout.addDrawerListener(new DrawerLayout.SimpleDrawerListener() {
//当侧滑菜单正在滑动时触发的方法
/**
第一个参数：正在滑动的侧滑菜单
第二个参数：菜单滑动的宽度的百分比
**/
@Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, slideOffset);
//获得侧滑菜单的宽度
int drawerViewWidth = drawerView.getMeasuredWidth();
//根据滑动百分比计算内容部分应该向右边移动的距离
int marginLeft = (int)(drawerViewWidth * slideOffset) ;
//获得内容部分的View对象（内容View对象是第一个，所以是0）
contentView = (LinearLayout) drawerLayout.getChildAt(0);
//修改内容部分的左边距
contentView.setLeft(marginLeft);
//解决DrawerLayout不能全屏滑动的问题,displayWidthPercentage传 1，即可实现全屏滑动。
// 如果你想让右侧菜单也是全屏，只要将对应的 "mLeftDragger" 改为 "mRightDragger"
setDrawerLeftEdgeSize(MainActivity.this,drawerLayout,1);
}
});
}
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.main_menu://点击菜单，跳出侧滑菜单
if (drawerLayout.isDrawerOpen(navigationView)){

drawerLayout.openDrawer(navigationView);

drawerLayout.getClass().getDeclaredField("mLeftDragger");//Right
leftDraggerField.setAccessible(true);
ViewDragHelper leftDragger = (ViewDragHelper) leftDraggerField.get(drawerLayout);
// 找到 edgeSizeField 并设置 Accessible 为true
Field edgeSizeField = leftDragger.getClass().getDeclaredField("mEdgeSize");
edgeSizeField.setAccessible(true);
int edgeSize = edgeSizeField.getInt(leftDragger);
// 设置新的边缘大小
Point displaySize = new Point();
activity.getWindowManager().getDefaultDisplay().getSize(displaySize);

displayWidthPercentage)));

}
} 思考如何关闭手势滑动？NavigationView的确没有相关关闭侧滑手势的属性，但是别忘了，drawerLayout却可以，通过以下属性可以关闭滑动手势操作：
在android抽屉开发中，需要关闭手势滑动，来滑出弹出框
mDrawer_layout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED)//关闭手势滑动
mDrawer_layout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);//打开手势滑动
NavigationView Item图标不显示原始颜色解决办法：
navigationView.setItemIconTintList(null);
