public class MainActivity extends BaseActivity{

private DrawerLayout drawerLayout ;
private Toolbar toolbar;
private NavigationView navigationView;
private View navigationHeaderView;
private ImageView ivCloseSlideMenu;
private ImageView ivDownArrow;

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

private void initView(){
toolbar = (Toolbar) findViewById(R.id.toolbar_activity_main);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout_activity_main);
navigationView = (NavigationView) findViewById(R.id.drawer_navigation);
navigationHeaderView = navigationView.getHeaderView(0);
ivCloseSlideMenu = navigationHeaderView.findViewById(R.id.img_close_slidemenu);
ivDownArrow = navigationHeaderView.findViewById(R.id.iv_down_arrow);
setSupportActionBar(toolbar);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawerLayout.setDrawerListener(toggle);

}

private void handleEvent(){
//侧滑菜单item点击事件处理：
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch(item.getItemId()){
case R.id.myExercises://我的练习
showToast("我的练习");
