Android上的导航抽屉滞后

您可以通过这种方式来避免抽屉滞后，更改 onItemClick ：

layoutDrawer.closeDrawer(linearDrawer);setLastPosition(posicao);new Handler().postDelayed(new Runnable() {        @Override        public void run() { setFragmentList(lastPosition);        }    }, 200);

编辑：
首选方式应该是在DrawerLayout上设置DrawerListener，然后

onDrawerClosed

Fragment mFragmentToSet = null;@Overridepublic boolean onNavigationItemSelected(@NonNull MenuItem item) {    // Handle navigation view item clicks here.    switch (item.getItemId()) {        case R.id.nav_home: mFragmentToSet = HomeFragment.newInstance();  break;    }    mDrawerLayout.closeDrawer(GravityCompat.START);    return true;}

mDrawerLayout.addDrawerListener(new DrawerLayout.DrawerListener() {        @Override public void onDrawerSlide(View drawerView, float slideOffset) {}        @Override public void onDrawerOpened(View drawerView) {}        @Override public void onDrawerStateChanged(int newState) {}        @Override        public void onDrawerClosed(View drawerView) {          //Set your new fragment here          if (mFragmentToSet != null) { getSupportFragmentManager()       .beginTransaction()       .replace(FRAGMENT_CONTAINER_ID, mFragmentToSet)       .commit(); mFragmentToSet = null;          }        }    });
