Kode saya berfungsi dengan baik: setiap kali item di Navigasi Drawer diklik item dipilih.
Tentu saja saya ingin memulai aplikasi dengan fragmen default (home), tetapi Navigasi Drawer tidak memiliki item yang dipilih. Bagaimana saya bisa memilih item itu secara terprogram?
public class BaseApp extends AppCompatActivity {
//Defining Variables
protected String LOGTAG = "LOGDEBUG";
protected Toolbar toolbar;
protected NavigationView navigationView;
protected DrawerLayout drawerLayout;
private DateManager db = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.base_layout);
navigationView = (NavigationView) findViewById(R.id.navigation_view);
// set the home/dashboard at startup
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.frame, new DashboardFragment());
fragmentTransaction.commit();
setNavDrawer();
}
private void setNavDrawer(){
// Initializing Toolbar and setting it as the actionbar
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//Initializing NavigationView
//Setting Navigation View Item Selected Listener to handle the item click of the navigation menu
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
// This method will trigger on item Click of navigation menu
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
//Checking if the item is in checked state or not, if not make it in checked state
// I THINK THAT I NEED EDIT HERE...
if (menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);
//Closing drawer on item click
drawerLayout.closeDrawers();
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId()) {
//Replacing the main content with ContentFragment
case R.id.home:
DashboardFragment dashboardFragment = new DashboardFragment();
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.frame, dashboardFragment,"DASHBOARD_FRAGMENT");
fragmentTransaction.commit();
return true;
[...]Saya pikir saya perlu mengedit di sini:
if (menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);Atau di onCreate Startup aplikasi dengan FragmentTransaction.
Terima kasih atas dukungan Anda.
