1.布局要注意的就是 
Android:layout_gravity=”right”

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

 

2.Java代码 
这个是设置toolbar里左上角menu按钮的点击事件

toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (!drawer.isDrawerOpen(setDrawerGravity())) {
                    drawer.openDrawer(setDrawerGravity());
                }
            }
        });

3.这里只有4个属性可用 

Gravity.LEFT to move the left drawer or Gravity.RIGHT for the right.GravityCompat.START or GravityCompat.END may also be used.

private int setDrawerGravity() {
        return Gravity.RIGHT;
    }

 

4.返回键处理

@Override
    public void onBackPressed() {
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        if (drawer.isDrawerOpen(setDrawerGravity())) {
            drawer.closeDrawer(setDrawerGravity());
        } else {
            super.onBackPressed();
        }
    }

5.NavigationView 的item点击处理

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener(){
            @Override
            public boolean onNavigationItemSelected(MenuItem item) {
                // Handle navigation view item clicks here.
                DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
                drawer.closeDrawer(setDrawerGravity());
                int id = item.getItemId();

                if (id == R.id.nav_camera) {
                    // Handle the camera action
                }
                return true;
            }
        });
