@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {

int id = menuItem.getItemId();

switch (id) {
case R.id.nav_setting:
Toast.makeText(this, "夜间模式", Toast.LENGTH_LONG).show();
if (isNightMode) {
uiManager.enableCarMode(0);
uiManager.setNightMode(UiModeManager.MODE_NIGHT_YES);
isNightMode = !isNightMode;
} else {
uiManager.disableCarMode(0);
uiManager.setNightMode(UiModeManager.MODE_NIGHT_NO);
isNightMode = !isNightMode;
}
