How to change activity when click drawer menu item? - android

I have a drawer menu which by Android Studio.
My menu's code:
//Menü kodları//
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);
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.setItemIconTintList(null);
}
#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 onNavigationItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.menu_fbdown) {
} else if (id == R.id.menu_instadown) {
} else if (id == R.id.menu_twitdown) {
} else if (id == R.id.menu_privacy) {
} else if (id == R.id.menu_about) {
} else if (id == R.id.menu_contact) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
I want to make clicktable this menu. I tired this code:
Intent i = new Intent(FBDownActivity.this, FBDownActivity.class);
startActivity(i);
Like this:
#Override
public boolean onNavigationItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.menu_fbdown) {
Intent i = new Intent(FBDownActivity.this, FBDownActivity.class);
startActivity(i);
} else if (id == R.id.menu_instadown) {
Intent i = new Intent(FBDownActivity.this, FBDownActivity.class);
startActivity(i);
} else if (id == R.id.menu_twitdown) {
} else if (id == R.id.menu_privacy) {
} else if (id == R.id.menu_about) {
} else if (id == R.id.menu_contact) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
But it's didn't work. Still can't click to item.
What Can I do about it?
Thanks.

You are trying to start the same activity as you are. Change the code bellow:
#Override
public boolean onNavigationItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.menu_fbdown) {
Intent i = new Intent(YourCurrentActivty.this, ActivityToOpen.class);
startActivity(i);
} else if (id == R.id.menu_instadown) {
Intent i = new Intent(YourCurrentActivty.this, ActivityToOpen.class);
startActivity(i);
} else if (id == R.id.menu_twitdown) {
} else if (id == R.id.menu_privacy) {
} else if (id == R.id.menu_about) {
} else if (id == R.id.menu_contact) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}

You don't need the OnClickListener of the TextView. Just do:
else if (id == R.id.nav_login) {
Intent i=new Intent(MainActivity.this, LoginActivity.class);
startActivity(i);
}

NavigationView click listener not working

I am trying to handle NavigationView click listener for back button but it is not working.
navigationView.setOnClickListener may be enough but may be it's due to some other reason that's why added full class

Answer found by Mike M Comment:
remove navigation.setOnClickListener and replace it to
toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (getSupportFragmentManager().getBackStackEntryCount() > 0)
onBackPressed();
}
});

Switching and clicking on fragments inside navigation drawer

I have made navigation drawer in Android Studio.
Right now each fragment from drawer is leading to nowhere.
I need to know how can I switch between fragments and click on each one
I know i need to make new fragment, but what method to use so I can click on Settings from navigation drawer so it lead me to fragment Share?
Here 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);
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);
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);
}
#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();
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;
}
}
You are in the right direction. Just add the Fragment class in each of the Navigation items like below
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
Fragment fragment = null;
FragmentManager fragmentManager = getSupportFragmentManager();
if (id == R.id.nav_camera) {
// Handle the camera action
fragment = new DefaultFragment();
fragmentManager.beginTransaction().replace(R.id.first_container, fragment).commit();
} else if (id == R.id.nav_gallery) {
fragment = new ItemListFragment();
fragmentManager.beginTransaction().replace(R.id.first_container, fragment).commit();
}
}
at the end of onCreate(Bundle savedInstanceState)method, you can set the default Fragment to open on Activity load.
FragmentManager fragmentManager = getSupportFragmentManager();
DefaultFragment fragment = new DefaultFragment();
fragmentManager.beginTransaction().replace(R.id.first_container, fragment).commit();
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.`enter code here`
int id = item.getItemId();
FragmentManager fragmentManager =getSupportFragmentManager();
GoogleMap googleMap =getSupportFragmentManager();
if (id == R.id.alarme){
} else if (id == R.id.map) {
fragmentManager.beginTransaction().replace(R.id.contenedor,new mapposta()).commit();
} else if (id == R.id.parametre) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;

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.
