How to check menu item in Android Navigation Drawer Template?

I'm using 'com.android.support:appcompat-v7:24.2.1' in my application; therefore, I generated a Navigation Drawer selecting it in the UI.
However, when I click in one item of the menu, it is not getting checked. Below is my code!
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
Fragment fragment = new PainelFragment();
replaceFragment(fragment);
navigationView.getMenu().getItem(0).setChecked(true);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
Fragment fragment = null;
if (id == R.id.nav_painel) {
// Handle the painel action
fragment = new PainelFragment();
} else if (id == R.id.nav_modelos) {

}

}

drawer.closeDrawer(GravityCompat.START);
return true;

Implementing back navigation with ToolBar and AppCompatActivity

I'm trying to change the Navigation drawer icon back arrow and use it as a back button. But when I getSupportActionBar().setDisplayHomeAsUpEnabled(true); nothing happens.
MainActivity.java
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
ActionBarDrawerToggle toggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
toggle = new ActionBarDrawerToggle(
this, drawer, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
#Override
public void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
//getSupportActionBar().setDisplayShowHomeEnabled(true);
toggle.syncState();
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(toggle.onOptionsItemSelected(item)) {
return true;
}
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_camera) {
// Handle the camera action
} else if (id == R.id.nav_gallery) {
} else if (id == R.id.nav_slideshow) {
} else if (id == R.id.nav_manage) {
} else if (id == R.id.nav_share) {
} else if (id == R.id.nav_send) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
When I change the constructor of the ActionBarDrawerToggle to
toggle = new ActionBarDrawerToggle(this, drawer, **toolbar**, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
the icon does change to back arrow, but it functions like a drawer toggle and not like a back button (because the onOptionsItemSelected is not called).
What is the correct way to make it work?
try this,
toggle.setDrawerIndicatorEnabled(false);
Happy Coding..

Using Navigation Bar Activity on different Activities with each Activity's content

I am trying to extend other activities into Navigation Bar Activity, I want to use content of the Activity with Navigation Drawer, but when I use setcontentView, Navigation Bar does not work.
This is my Navigation Bar Activity :
:
public class navigationdrawer extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigationdrawer);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.navigationdrawer, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_dashboard) {
Intent i = new Intent(navigationdrawer.this, dashboard.class);
startActivity(i);
// Handle the camera action
} else if (id == R.id.nav_community) {
} else if (id == R.id.nav_recipes) {
Intent i = new Intent(navigationdrawer.this, Recipe.class);
startActivity(i);
} else if (id == R.id.nav_leaderboard) {
} else if (id == R.id.nav_upload) {
} else if (id == R.id.nav_mypics) {
} else if (id == R.id.nav_myvideos) {
} else if (id == R.id.nav_settings) {
} else if (id == R.id.nav_contactus) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
This is my Second Activity :
public class Recipe extends navigationdrawer{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(new View(this));
// Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
// setSupportActionBar(toolbar);
}
}
I have commented setcontentview statement as I know that setcontentview is getting called in the Navigation Drawer Activity but I want Navigation Drawer and the content both. How to achieve this task?
Use fragment instead of activities
Fragment is an part of activity. so, if you want to use singledrawer throughout the app then it is better to use fragment inside your navigationbar activity
note :
use fragment view inside your navigation drawer activity
like
if (id == R.id.nav_dashboard) {
// write code for fragment replacement
}

How to change selected Item in the navigation drawer depending on the activity/view?

I have a Navigation Drawer Activity and different activities in which I get. I want the Items in the nav drawer being selected depending on the activity or view whatever.
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(view.getContext(), MainAddMedActivity.class);
/*EditText editText = (EditText) findViewById(R.id.search_medicament);
String medicament_search = editText.getText().toString();*/
/*intent.putExtra(EXTRA_MESSAGE, medicament_search);*/
startActivity(intent);
}
});
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.getMenu().getItem(0).setChecked(true);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
/*navigationView.getMenu().getItem(0).setChecked(true);*/
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_healthdiary) {
} else if (id == R.id.nav_appointment) {
} else if (id == R.id.nav_physician) {
} else if (id == R.id.nav_protocol) {
} else if (id == R.id.nav_share) {
} else if (id == R.id.nav_send) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
For example, I get into the MainAddMedActivity and Press back. Then I want some code to check in which view or activity I am and select the item in the navigation drawer.
Seems like you have not yet implemented the switching of the content area. I suggest you use fragments for this.
So, if you use fragments, override onAttachFragment of your activity like:
#Override
public void onAttachFragment(Fragment fragment) {
super.onAttachFragment(fragment);
int id;
if(fragment instanceof HealthDiaryFragment) id = R.id.nav_healthdiary;
else
if(fragment instanceof AppointmentFragment) id = R.id.nav_appointment;
...
else return;
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setCheckedItem(id);
}
Also, modify your onBackPressed:
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
if(getFragmentManager().getBackStackEntryCount()>1) {
getFragmentManager().popBackStack();
}
else {
super.onBackPressed();
}
}
/*navigationView.getMenu().getItem(0).setChecked(true);*/
}
This is assuming that in your handling of drawer selection you replace fragments with pushing them on the back stack.
