I have a navigation drawer activity with fragments and I will send each fragment to an activity. I have a problem if I select option 3 of my menu that is a fragment that will send me to an activity, but when I return with the Back button, it sends me to option 1, what I want is that I return to option 3.
How can I change this?
I tried to do it by parentActivity but it did not work
Thank you.
My navigation drawer activitywithfragments
When I click on the button, it sends me to an activity that is this
And in the activity I have a toolbar to return and what I want is to return to option 3 and not to 1.
What do I need to do in my code or what can I place?
My fragment code option 3
public class Mis_Aliados extends Fragment {
Button boton;
public Mis_Aliados() { }
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.persona_mi_perfil, container, false);
boton=view.findViewById(R.id.buton);
boton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getActivity(), ActividadEx.class);
startActivity(intent);
}
});
return view;
}
}
My activity code
public class ActividadEx extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.pruebaactividad);
Toolbar toolbarback=findViewById(R.id.include);
setSupportActionBar(toolbarback);
getSupportActionBar().setTitle("Activity");
ActionBar actionBar=getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
}
}
In your ActividadEx add this method to handle toolbar back button press
I'm putting 1 intent extra to make sure you want to open Option 3 when you are back to Navigation drawer Activity
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
Intent intent = new Intent(this, NavgationDrawerActivity.class);
intent.putExtra("openOption3", true);
startActivity(intent);
}
return super.onOptionsItemSelected(item);
}
On NavigationDrawerActivty inside onCreate()
you can check if Bundle has data or not. If its empty you can open Option1 fragment.
If it has data check it. and open Option3 Fragment.
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
if (bundle.getBoolean("openOption3", false)) {
//Use Fragment Transaction to Open Option 3 Fragment
} else {
//Open Option 1 Fragment Or any other Fragment
}
} else {
//Open Option 1 Fragment Or any other Fragment
}
Feel free to comment if you've any queries.
I have the following Activity code:-
public class legislator_info extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_legislator_info);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle("Legislator Info");
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Intent i = getIntent();
String bioguide = i.getExtras().getString("Person");
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// click on 'up' button in the action bar, handle it here
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
So basically I have a fragment which has a list view displayed in it. On click of a list Item I start this activity and I want to go back to the previous fragment on the back button click. I tried the above code but I am not able to travel back. Am pretty new at this any help is appreciated.
I have added my fragment in the following way:-
android.support.v4.app.FragmentManager fm = getSupportFragmentManager();
android.support.v4.app.FragmentTransaction ft = fm.beginTransaction();
LegislatorFragment lf = new LegislatorFragment();
ft.replace(R.id.fragment_container,lf);
ft.addToBackStack(null);
ft.commit();
I am still not clear what you want to achieve but you can try this
#Override
public void onBackPressed() {
super.onBackPressed();
finish();
}
EDIT:
case android.R.id.home:
//call onBackPressed here
onBackPressed();
return true;
You have to override onOptionsItemSelected because you are trying with Action bar's back button.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
onBackPressed();
return true;
}
return super.onOptionsItemSelected(item);
}
Then override BackPressed -
#Override
public void onBackPressed()
{
FragmentManager fm = getSupportFragmentManager();
if (fm.getBackStackEntryCount() > 0) {
fm.popBackStack();
}
else {
super.onBackPressed();
}
}
I've just followed answers from this site and but they doesn't work for me. I am gonna have few activities and I want to have a back button on the action bar but it doesn't seems to appear. I am using API 16 for minimum sdk and I've set the parent Activity to the secondary activity.
Here's my code.
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
}
if (id == R.id.action_options) {
Intent i = new Intent(this, Settings.class);
startActivity(i);
return true;
}
return super.onOptionsItemSelected(item);
}
}
You probably meant setDisplayHomeAsUpEnabled, not setDefaultDisplayHomeAsUpEnabled. Not sure what the latter is anyway.
You missed setting setDisplayShowHomeEnabled(true). setDisplayHomeAsUpEnabled(true) is not enough.
final ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayShowHomeEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(true);
}
I have problem with the back button in action bar to fragment
my code fragment:
public class Server extends Fragment {
View view;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
view = inflater.inflate(R.layout.activity_server, container, false);
Button server = (Button) view.findViewById(R.id.status);
/** Button Check Status Server **/
server.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
Intent myIntent = new Intent(view.getContext(), ServerStatus.class);
startActivityForResult(myIntent, 0);
getActivity().finish();
}
});
return view;
}
}
my code in activity:
public class ServerStatus extends ActionBarActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_server_status);
}
}
My code in Fragment
#Override
public void onNavigationDrawerItemSelected(int position) {
Fragment objFragment = null;
switch (position) {
case 0:
objFragment = new Account();
break;
case 1:
objFragment = new AllNews();
break;
case 2:
objFragment = new Server();
break;
case 3:
objFragment = new Account();
break;
case 4:
objFragment = new Account();
break;
case 5:
objFragment = new Account();
break;
case 6:
objFragment = new About();
break;
}
// update the main content by replacing fragments
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container,objFragment)
.commit();
}
Every time I click the back button, the program always closes. I already tried to use:
getActionBar().setDisplayHomeAsUpEnabled(true);
and this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// Respond to the action bar's Up/Home button
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
}
return super.onOptionsItemSelected(item);
}
Can anyone help me to fix my program?
EDIT: Concerning cross-activity-navigation, you should not use startActivityForResult() in that way. Try to use startActivity() instead. If you start an activity for a result, the calling activity waits for the onActivityResult() callback and should not be finished.
In the manifest file you should declare the fragment's activity as parent activity of ServerStatus to enable back navigation. You should not need NavUtils.
If you want to enable fragment navigation within an activity, you have to add your fragment transactions to the backstack:
getFragmentManager().beginTransaction().addToBackStack(null).replace(...).commit();
Then you have to call getFragmentManager().popBackStack() in onOptionsItemSelected() to enable back navigation for the action bar:
#override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// Respond to the action bar's Up/Home button
case android.R.id.home:
getFragmentManager().popBackStack();
return true;
}
return super.onOptionsItemSelected(item);
}
You may have to override onBackPressed() to enable back navigation for the back button:
#override
public void onBackPressed() {
if (getFragmentManager().getBackStackEntryCount() >= 1) {
getFragmentManager().popBackStack(); // return to previous fragment
}
else {
super.onBackPressed(); // Exit application when no fragment is on the backstack
}
}
with the help of these Android Docs.I am trying to do a action bar Back button.I get an Action Bar Back Button like these below image:
Output:
But My problem is After watching the Gallery images I press the action bar back button.
Then it is not working.But it have to go back to previous page.
Listed below are the codings.
GalleryActivity.java:
import android.app.ActionBar;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.NavUtils;
import android.view.MenuItem;
import com.fth.android.R;
public class GalleryActivity extends FragmentActivity {
private int position;
private static String id;
private static String name;
private DemoCollectionPagerAdapter mDemoCollectionPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gallery);
position = getIntent().getExtras().getInt("position");
id = getIntent().getExtras().getString("id");
name = getIntent().getExtras().getString("name");
mDemoCollectionPagerAdapter = new DemoCollectionPagerAdapter(getSupportFragmentManager());
// Set up action bar.
final ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
// getActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_HOME|ActionBar.DISPLAY_USE_LOGO|ActionBar.DISPLAY_HOME_AS_UP);
// Set up the ViewPager, attaching the adapter.
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mDemoCollectionPagerAdapter);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
Intent upIntent = new Intent(this, HomeActivity.class);
upIntent.putExtra("position", position);
if (NavUtils.shouldUpRecreateTask(this, upIntent)) {
TaskStackBuilder.from(this)
.addNextIntent(upIntent)
.startActivities();
finish();
} else {
NavUtils.navigateUpTo(this, upIntent);
}
return true;
}
return super.onOptionsItemSelected(item);
}
}
GalleryDetailFragment.java:
import com.sit.fth.model.GalleryDetail;
import com.sit.fth.util.APIServiceHandler;
import com.sit.fth.util.AppConstants;
import com.sit.fth.util.AppPromoPager;
public class GalleryDetailFragment extends BaseFragment implements
PromoPagerListener {
private TextView countView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
this.setHasOptionsMenu(true);
id = getArguments().getString("id");
name = getArguments().getString("name");
View view = inflater.inflate(R.layout.app_pager, null);
return view;
}
}
Anybody can help me if you know how to solve these.Thank You.
I solved these problem by adding the below coding in GalleryActivity.
ActionBar actionBar;
actionBar=getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
onBackPressed();
return true;
}
return super.onOptionsItemSelected(item);
}
In MainActivity:
Previously,
public class HomeActivity extends BaseActivity
Then I change into
public class HomeActivity extends FragmentActivity
In GalleryFragment:
I use Intent to pass it to the GalleryActivity.
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Gallery gallery = (Gallery) arg0.getAdapter().getItem(arg2);
Intent intent = new Intent(getActivity(), GalleryActivity.class);
intent.putExtra("position", position);
intent.putExtra("id", gallery.getGalId());
intent.putExtra("name", gallery.getAlbumTitle());
startActivity(intent);
// mCallback.OnGalItemSelected(gallery.getGalId(),gallery.getAlbumTitle());
}
Please read this
you should have something like this:
<activity
android:name="com.sit.fth.activity.HomeActivity"
android:screenOrientation="portrait">
</activity>
<activity
android:name="com.sit.fth.activity.GalleryActivity"
android:screenOrientation="portrait"
android:parentActivityName="com.sit.fth.activity.HomeActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.sit.fth.activity.HomeActivity"/>
</activity>
then calling NavUtils.navigateUpFromSameTask(this) will cause navigating to parent activity (HomeActivity).
You need to call setDisplayHomeAsUpEnabled(true) method in the onCreate method and override onSupportNavigateUp() and call onBackPressed() in it as below. That's it. done :)
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_help);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onSupportNavigateUp() {
onBackPressed();
return true;
}
You have just to add the following line to the activity in the manifest.xml. The parent activity is the activity to which you want to go back.
android:parentActivityName=".activities.MainActivity"
Try like
First of all you need to use addToBackStack() before commit() for Fragments
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// Respond to the action bar's Up/Home button
case android.R.id.home:
if(getSupportFragmentManager().getBackStackEntryCount()>0)
getSupportFragmentManager().popBackStack();
return true;
}
return super.onOptionsItemSelected(item);
}
Best and easy answer is add the parent activity name in Manifest file, so Actionbar back button will work.
For that under that Activity tag of Manifest File use
android:parentActivityName=".MyCustomParentActivity"
if the home button is shown. you should add an action to the home button through onOptionItemSelected fun (arrow in your case) by default there's no action. so it's totally normal that it's not working. Please add this fun to your activity :
override fun onOptionsItemSelected(item: MenuItem): Boolean {
return when {
item.itemId == android.R.id.home -> {
finish()
true
}
else -> super.onOptionsItemSelected(item)
}
}
None of the answers provided here worked for me. I had to put the switch inside the onMenuItemSelected method. I'm aware this is not what is stated in the Android documentation, but still, it worked, so I just thought I'd leave this here for people who run into the same issue. My problem involved an Activity instead of a Fragment though, but that should be pretty much the same.
class FooActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// ...
getActionBar().setHomeButtonEnabled(true);
getActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
}
return false;
}
}
To me, I had to set mDrawerToggle.setToolbarNavigationClickListener(...) to a listener that triggers the back action. Otherwise it does nothing. This is what the source code of ActionBarDrawerToggle looks like:
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mDrawerIndicatorEnabled) {
toggle();
} else if (mToolbarNavigationClickListener != null) {
mToolbarNavigationClickListener.onClick(v);
}
}
});
So the default behaviour is actually to call our listener, and not do any magic on its own.
Use on SupportNavigateUp() method and call onBackPressed in this method.
onCreate
{
...
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
resetActionBar();
...
}
public void resetActionBar()
{
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
#Override
public void onBackPressed() {
FragmentManager fm = getSupportFragmentManager();
int count = fm.getBackStackEntryCount();
if(count == 0) {
// Do you want to close app?
showDialog();
}else{
super.onBackPressed();
}
}
#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();
Log.i("coming", "comming");
//noinspection SimplifiableIfStatement
if(id==android.R.id.home){
if (getSupportFragmentManager().getBackStackEntryCount() > 0)
onBackPressed();
else
drawerLayout.openDrawer(navigationView);
return true;
}
return super.onOptionsItemSelected(item);
}
Here is one more thing to check for in case the other answers here (or here or here or here) don't work.
I had copied some code from another activity that disabled the menu. Deleting this method (and applying the solutions given in the others answers) allowed the up button to work.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// hide the menu
return false;
}
In my case I had overridden the onCreateOptionsMenu method and I forgot to call super at the end.
Tool bar enable back button for Kotlin binding
setSupportActionBar(binding.toolbar)
