我在我的应用程序中使用导航抽屉,你可以在android工作室添加,我在Nav抽屉中添加了一些菜单条目(参见代码块)。如果我按下第一个项目(nav_home)或第二个项目,导航抽屉会突出显示当前按下的项目。
如果我按下“nav_information”按钮或其他项目,则会显示新的(单击的)片段opend并且不会突出显示(主页或第二项仍然突出显示)
很快,只有第一项显示所选项目的突出显示。

@Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
Fragment myFragment = null;
if (id == R.id.nav_home) {
drawer.setSelected(true);
myFragment = new MainScreen();
}else if (id == R.id.nav_greetings){
myFragment = new Greetings();
} else if (id == R.id.nav_information) {
myFragment = new Aktuelles();
} else if (id == R.id.nav_directions) {
myFragment = new Anfahrt();
} else if (id == R.id.nav_basilika) {
myFragment = new Rundabout();
} else if (id == R.id.nav_download) {
myFragment = new Downloads();
} else if (id == R.id.nav_history) {
myFragment = new History();
}else if(id == R.id.nav_hauptwallfahrt){
myFragment = new Hauptwallfahrt();
}else if (id == R.id.nav_themenwallfahrt){
myFragment = new Themenwallfahrt();
}else if (id == R.id.nav_pilgergruppen){
myFragment = new Pilgergruppen();
}else if (id ==R.id.nav_wallfahrtgodi){
myFragment = new Wallfahrtsgottesdienste();
}
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction ft = fragmentManager.beginTransaction();
// Replace the requestet Fragment
ft.replace(R.id.container, myFragment) ;
ft.commit();
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
这就是我处理片段打开的方式。

有没有办法“启用”突出显示?
