I am trying to add click functionality on the Actionbar back button. I have tried the below things till now, but unable to get the desired result.
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Observed that the onClick method is not being called when i click on the back button in the action bar
toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close) {
};
drawer.setDrawerListener(toggle);
drawer.post(new Runnable() {
#Override
public void run() {
toggle.syncState();
}
});
toggle.setDrawerIndicatorEnabled(true);
toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onKeyDown(4, null);
}
});
Use the updated code
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
switch (item.getItemId()) {
case android.R.id.home:
showToast("Test");
return true;
}
you can try like this
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayShowHomeEnabled(true);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
});
use following code inside your Activity :
//for going back or finish current activity.
#Override
public boolean onSupportNavigateUp() {
finish();
startActivity(new Intent(ResultActivity.this, MainActivity.class));
return true;
}
Below code are for actionBar menu.
#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, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.logout) {
// toast Here
return true;
}
if (id == R.id.home) {
// toast Here
return true;
}
return super.onOptionsItemSelected(item);
}
onCreateOptionsMenu() is used for creating your menu & setting your menu.xml
onOptionsItemSelected() is used for selection of menu items & actions.
This question already has answers here:
When toolbar back button is pressed
(4 answers)
Closed 6 years ago.
how can I create a code for my android app where When I pressed the back button on the toolbar (Action Bar) some code will happening.
I tried but it does not work.
Added in main activity. onbackpress method
#Override
public void onBackPressed() {
super.onBackPressed();
stopActivityTask();
}
You can Try this way..
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// this takes the user 'back', as if they pressed the left-facing
triangle icon on the main android toolbar.
// if this doesn't work as desired, another possibility is to call
stopActivityTask(); // finish() here.
getActivity().onBackPressed();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
If Not Work
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
// Title and subtitle
toolbar.setTitle(R.string.about_toolbar_title);
toolbar.setNavigationIcon(R.drawable.ic_action_back);
toolbar.setNavigationOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
stopActivityTask();
finish();
}
});
private Toolbar toolbar;
Then add this in your onCreate method
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Then you add these lines :
#Override
public boolean onOptionsItemSelected(MenuItem item) {
/*
ADD WHAT YOU WANT TO DO WHEN ARROW IS PRESSED
*/
return super.onOptionsItemSelected(item);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
// click on icon to go back
//triangle icon on the main android toolbar.
if (id == android.R.id.home) {
//your code
return true;
}
return super.onOptionsItemSelected(item);
}
I am working on an android webview app, i have added share action on action bar which works fine when showAsAction is 'never, but stop working as soon as i change it to 'always' or 'ifRoom'`
my code is:
private ShareActionProvider mShareActionProvider;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public final boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_item_share:
shareURL();
}
return super.onOptionsItemSelected(item);
}
private void shareURL() {
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT, mWebView.getUrl());
startActivity(Intent.createChooser(shareIntent, "Share This!"));
}
if someone could help, thank you.
Remove the android:actionProviderClass="android.widget.ShareActionProvider" and add the android:icon="#drawable/image-name"
Are you sure you actually have space to display it?
You could try disabling the title to see is that created enough room:
ActionBar actionBar = getActionBar();
actionBar.setDisplayShowTitleEnabled(false);
Update:
Can you try using:
public void setOnMenuItemClickListener (Toolbar.OnMenuItemClickListener listener)
I believe the toolbar has a separate listener than the dropdown menu.
The code could look something like:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar tb = (Toolbar) findViewById(R.id.toolbar_id);
tb.inflateMenu(R.menu.menu);
tb.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
// Menu item should be returned here (the one you tap on the toolbar)
return false;
}
});
}
I used Toolbar component in AppCompat library instead of Default Actionbar.
Compile time: I get compile-error that cannot find symbol android.R.id.home
public void setupActionBar() {
// Set a Toolbar to replace the ActionBar.
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if(id == R.id.action_help) {
showHelp();
return true;
}else if(id == android.R.id.home){
Log.d(TAG, "Back Button clicked!");
this.finish();
return true;
}
return super.onOptionsItemSelected(item);
}
android.R.id.home was introduced in API level 11.

add this to your activity.
#Override
public void onBackPressed() {
// your code.
this.finish();
}
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.
