res string资源：
<string name="navigation_drawer_open">Open navigation drawer</string>
<string name="navigation_drawer_close">Close navigation drawer</string>
代码中：
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
}
private void init() {
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
//执行这行代码，菜单栏的标题会显示
//setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
//推荐使用，设置菜单滑动监听（原来的drawer.setDrawerListener废弃）
drawer.addDrawerListener(new DrawerLayout.DrawerListener() {
@Override
public void onDrawerSlide(View drawerView, float slideOffset) {
}
@Override
public void onDrawerOpened(View drawerView) {
}
@Override
public void onDrawerClosed(View drawerView) {
}
@Override
public void onDrawerStateChanged(int newState) {
}
});
}
@Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
补充：
1、必须指定侧滑菜单布局的android:layout_gravity属性，从左向右滑出菜单：android:layout_gravity = "start"；从右向左滑出菜单：android：layout_gravity = "end"时，不建议使用left和right！（该属性定义菜单的位置，主布局不用写该属性）
2、侧滑菜单的宽度可以直接设置，以dp为单位，不建议超过320dp，通常设置为240dp
3、常用设置
打开侧拉菜单：
mDrawerLayout.openDrawer(Gravity.LEFT);
关闭侧拉菜单：
mDrawerLayout.closeDrawer(menu_layout);
菜单是否开启，开启返回true，关闭返回false：
mDrawerLayout.isDrawerOpen(menu_layout);
