For some reason the overflow dots do not appear on my tablet for my master detail application when I select a list item but yet they do on my handset. I'm not sure why is occurring despite using the necessary code. Does anyone there is any code missing or that shouldn't be there?
MainActivity.java
public class MainActivity extends ActionBarActivity {
private boolean mTwoPane;
#Override
protected void onCreate(Bundle savedInstanceState) {
try {
ViewConfiguration config = ViewConfiguration.get(this);
Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
if (menuKeyField != null) {
menuKeyField.setAccessible(true);
menuKeyField.setBoolean(config, false);
}
}
catch (Exception e) {
e.printStackTrace();
}
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionBar = getSupportActionBar();
actionBar.setTitle(getResources().getString(R.string.greeting));
FragmentMainList newFragment = new FragmentMainList();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.master_container, newFragment);
transaction.commit();
if (findViewById(R.id.detail_container) != null) {
mTwoPane = true;
}
}
}
Activity Class
public class MyProductActivity extends ActionBarActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_fragment);
if (savedInstanceState == null) {
FragmentProduct newFragment = new FragmentProduct();
FragmentTransaction transaction = this.getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.detail_container, newFragment);
transaction.commit();
}
ActionBar actionBar = getSupportActionBar();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.my_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
final Intent intent = NavUtils.getParentActivityIntent(this);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
NavUtils.navigateUpTo(this, intent);
return true;
}
return super.onOptionsItemSelected(item);
}
}
Fragment Class
public class FragmentProduct extends android.support.v4.app.Fragment {
public FragmentProduct() {}
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_product, container, false);
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
return v;
}
#Override

return true;
}
int id = item.getItemId();
if (id == R.id.action_options) {
}
return super.onOptionsItemSelected(item);
}
}
The dots will be shown only for devices which don't have hardware Menu button. For devices with a hardware Menu button no overflow dots are shown since tapping on the menu button will do the same.
For more here
Edit
If for some reason you really want to show it, you can add below code in your Application.onCreate() or main (launcher) activity onCreate()
// force show actionbar 'overflow' button on devices with hardware menu button
try {
ViewConfiguration config = ViewConfiguration.get(this);
Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
if (menuKeyField != null) {
menuKeyField.setAccessible(true);
menuKeyField.setBoolean(config, false);
}
}
catch (Exception e) {
e.printStackTrace();

Basically my project have to have different toolbars, one for each fragment switched by the bottom navigation bar.
The fragment toolbars items are clickable, when I long press, shows the title item etc, but they don't perform the action. For example, When I set to show a toast when click on that item, he'll not perform. Any Suggestion? Thanks.
public class FeedFragment extends Fragment {
public static final String TAG = "Tag Free";
DialogFragment mDialog;
FloatingActionButton fab;
RevealFrameLayout reveal;
FrameLayout frame;
private ConstraintLayout layoutDialog;
boolean isOpen = false;
public FeedFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_feed, container, false);
/** Toolbar **/
Toolbar myToolbar = (Toolbar) view.findViewById(R.id.my_toolbar);
((AppCompatActivity) getActivity()).setSupportActionBar(myToolbar);
ActionBar ab = ((AppCompatActivity) getActivity()).getSupportActionBar();
ab.setDisplayHomeAsUpEnabled(false);
// navigation bottom
fab = getActivity().findViewById(R.id.fab_button);
fab.setImageDrawable(getResources().getDrawable(R.drawable.ic_pencil_black_24dp));
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
FragmentTransaction ft = getFragmentManager().beginTransaction().setCustomAnimations(R.anim.hold, R.anim.slide_down);
Fragment prev = getFragmentManager().findFragmentByTag("dialog");
if (prev != null) {
ft.remove(prev);
}
ft.addToBackStack(null);

case R.id.action_personProfile:
Toast.makeText(getActivity(),"not responding",Toast.LENGTH_SHORT).show();

startActivity(intent);
return true;
case R.id.action_settings:
Toast.makeText(getActivity(),"not responding",Toast.LENGTH_SHORT).show();
return true;
default:
// If we got here, the user's action was not recognized.
// Invoke the superclass to handle it.
return super.onOptionsItemSelected(item);
}
}
}
You are not chaining to the superclass in the activity methods.
Refactor your code as below :
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.appbar_feed, menu);
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_personProfile:
Toast.makeText(getActivity(),"not responding",Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getActivity(), MyUserProfileActivity.class);
startActivity(intent);
break;
case R.id.action_settings:
Toast.makeText(getActivity(),"not responding",Toast.LENGTH_SHORT).show();
break;
default:
// If we got here, the user's action was not recognized.
// Invoke the superclass to handle it.
break;
}
return super.onOptionsItemSelected(item);
}
Hope now your code will work fine.

Thanks,

Try using setTitle():
public boolean setSelected(int selected) {
switch (selected){
case R.id.welcome:
toolbar.setTitle("Welcome");
......
}
.....
}
Try using:
getSupportActionBar().setTitle("title");
in the switch-case
I think you could use something like this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuItem item = menu.add(Menu.NONE, ID, POSITION, TEXT);
item.setIcon(R.drawable.drawable_resource_name);
item.setShowAsAction(MenuItem.SHOW_AS_ACTION_WITH_TEXT);
return true;
}
Also this link might help: Here
Hope it helps ;)
btw your app looks great!
I have this called on my Fragment
#Override
public boolean onOptionsItemSelected(MenuItem item) {
Toast.makeText(getActivity(), "otem: " + item.getItemId(), Toast.LENGTH_SHORT).show();
switch (item.getItemId()) {
case android.R.id.home:
getFragmentManager().popBackStack();
((ActionBarActivity)getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(false);
return true;
}
return super.onOptionsItemSelected(item);
}
What the code above tries to do is to actually go to the previous intent when the back button (home button) at the actionbar is being clicked, instead of displaying the navigation drawer. But it seems everything inside the onOptionsItemSelected in the fragment isn't being executed. (Because if it is, it would display a toast.. I also put a linebreak there) Why?

Did you call this.setHasOptionsMenu(true); in onCreate()?
Report that this fragment would like to participate in populating the options menu by receiving a call to onCreateOptionsMenu(Menu, MenuInflater) and related methods.

So i've just started doing some android programing, and I'm already stuck! My problem is; I want want my fragment, from MainActivity, to NOT be a part of my new Activity. I want the activity to be all blank, the fragment from MainActivity should be gone, buuut it's not.
The content from the "fragmentz" xml document, which is "linked" in the Fragment Class. Should NOT appear in the second Activity... Where in the SecondActivity have I associated it with the Fragment Class? This is getting frustrating :D
So here is my MainActivity code:
public class MainActivity extends ActionBarActivity {
FragmentManager manager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}
manager= getSupportFragmentManager();
ArticleFragment frag = new ArticleFragment();
FragmentTransaction transaction = manager.beginTransaction();
transaction = manager.beginTransaction();
transaction.add(R.id.fragmentet,frag,"tagg");
transaction.commit();
// here the Fragment should be added to my MainActiviy
}
public void WalkForward(View view)
{
ArticleFragment frag = (ArticleFragment) manager.findFragmentByTag("tagg");
FragmentTransaction transaction = manager.beginTransaction();
transaction.remove(frag);
transaction.commit();
// Here, the fragment should disappear before the new activity start
Intent intenten = new Intent(this, SecondActivity.class);
startActivity(intenten);
// Start new activity
finish();
// I've tried this finish method, and also onDestroy and so on... But that work either. I thought the Fragments should
// disappear with its activity?
}
#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;
}

if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()

#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.second, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will

int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**

public static class PlaceholderFragment extends Fragment {
public PlaceholderFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_second,

I hope you understand what I mean :P Is there anything I can do? Thanks in advance!
Remove this
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}
from your Second Activity. And why are you extending MainActivity? Some Reason?
I am using Action Bar Sherlock fragments for my application. I need to go to fragment from activity. But sliding menu is not working when I goes to fragment by using this code.
Activity Code
Intent notificationIntent = new Intent(context,FragmentOpenActivity.class);
FragmentOpenActvity is like
public class FragmentOpenActivity extends SherlockFragmentActivity {
private Bundle i_fragment;
private String messages = null;
private String coupons = null;
private String yo = null;
private String invitation = null;
private String loyalty = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
if (savedInstanceState == null) {
// getSupportFragmentManager().beginTransaction()
// .add(android.R.id.content, new MessagesFragment()).commit();
i_fragment = getIntent().getExtras();
if (i_fragment == null) {
getSupportFragmentManager().beginTransaction()
.add(android.R.id.content, new ProfileEditorFragment())
.commit();
} else {
messages = i_fragment.getString("Message");
coupons = i_fragment.getString("Coupon");
}
if (messages != null && messages.equalsIgnoreCase("Message")) {
getSupportFragmentManager().beginTransaction()
.add(android.R.id.content, new MessagesFragment())
.commit();
} else if (coupons != null && coupons.equalsIgnoreCase("Coupon")) {
getSupportFragmentManager().beginTransaction()
.add(android.R.id.content, new CouponsFragment())
.commit();
} else {
getSupportFragmentManager().beginTransaction()
.add(android.R.id.content, new ProfileEditorFragment())
.commit();
}
}
}
/**
* #return Displaying Action Bar Button with Image
*/
#Override
public boolean onCreateOptionsMenu(Menu menu) {
return true;
}
/**
* #return Click Events for Action Bar Buttons
*/
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
startActivity(new Intent(this, FragmentChangeActivity.class));
break;
}
return true;
}
/**
* #return Handling Back button
*/
public void onBackPressed() {
startActivity(new Intent(this, FragmentChangeActivity.class));
finish();
}
}
Please refer the following code for fragment
public class CouponsFragment extends SherlockFragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
getSherlockActivity().getSupportActionBar().setDisplayOptions(
ActionBar.DISPLAY_SHOW_CUSTOM);
getSherlockActivity().getSupportActionBar().setDisplayHomeAsUpEnabled(
true);
return inflater.inflate(R.layout.listview_refreshable, null);
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
public void onStart() {
super.onStart();
}
}
Normally sliding menu works perfectly but when i came from FragmentOpenActivity it is not responding. Please try to find me a solution
