I am trying to get an action button to appear in my action bar, however I am only able to get the action overflow to show up instead of the drawable. Here is what I see.
Here is my menu_friends.xml source:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:binder="http://schemas.android.com/apk/res-auto" >
<!-- action_friends should appear as action button -->
<item android:id="#+id/action_friends"
android:icon="#drawable/ic_account_plus_grey600_24dp"
android:title="#string/menu_edit_friends_label"
binder:showAsAction="always" />
</menu>
Here is the fragment where I am inflating the menu:
public class FriendsFragment extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setHasOptionsMenu(true);
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_friends, container, false);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
menu.clear();
inflater.inflate(R.menu.menu_friends, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_friends:
navigateToEditFriends();
}
return super.onOptionsItemSelected(item);
}
private void navigateToEditFriends() {
Intent myIntent = new Intent(FriendsFragment.this.getActivity(), EditFriendsActivity.class);
startActivity(myIntent);
}
}
Here is my MainActivity code:
public class MainActivity extends FragmentActivity {
private static final String TAG = MainActivity.class.getSimpleName();
private PagerSlidingTabStrip tabs;

Put the setHasOptionsMenu() in your Fragments onCreate methode and not in onCreateView() methode. That should do the trick.

There is some information that I want to display in the NavigationDrawer. This information is entered by the user in a previous activity. I use an intent to send the information to the Main Activity for the Drawer.

I have a specific layout for the navigation drawer and it contains a textview which I want to update with the String test. This is the fragment code and the xml for it.

I have managed to update the list in the drawer with Icons, Labels and a Header. I have done so by using a RecyclerViewAdapter.
The problem that I am having is that these details were from the resources (strings.xml).
How can I update a textview on a NavigationFragment when it has been created? How can I send a value to the fragment so that it will be used during OnCreateView of the fragment?
I was looking too much into it. The solution was quite simple...Even though it took me 3 hrs to figure this out :/
In the NavigationFragment, I created a method to update a textview with a string. In the MainActivity where I get the information from the intent, I just called the method like this:
drawerFragment.setUserTextView(info);
This is why taking breaks are important... ^^
I have a really interesting problem with my Navigator menu.
I have no idea why... But I can click on any item from my menu, I don't want to say I click and nothing happened. I really want to say I can't click on any item, all my menu it's like a big image.
I've try to make a new project witch already have Navigation Drawer Activity, of course it works.. but when I've try to copy that code and put on mine.. I have the same problem and vice versa, I've try to put my code into a new project with Navigation Drawer Activity, but again... I can't click on any item.
Here it's one image with my aplication.

I want to implement Left & Right Side Slider Menu so I have set Right Side Slider in NavigationDrawerSlider which already have Left Side Slider by Default.
I am using ActionBarSherLock for this to support Application from Api 8. Slider is working fine but issue is that ActionBar is not showing Title.
Please help me to solve this issue. One more thing, When I Click on ImageView, It also fires ActionBarDrawerToggle. So, how to prevent this also ?

I have figured out that It is not showing title because of
actionBar_Right = getSupportActionBar();
actionBar_Right.setCustomView(R.layout.right_menu);
actionBar_Right.setDisplayShowTitleEnabled(true);
actionBar_Right.setDisplayShowCustomEnabled(true);
What to do for this ?
For showing the title in the ActionBar setTitle must be overridden:
#Override
public void setTitle(CharSequence title)
{
this.title = title;
getSupportActionBar().setTitle(title);
}
I have a Main Drawer activity which loads my fragments when a drawer item is selected. The fragment that is laoded contains a tabhost which hosts multiple fragments so you can switch to via tabs.
Before Tabs I had a fragment with a bunch of butons that when clicked, replaced the current fragment with a new fragment. The fragments all have listviews in them, and when you click an item replaced the current listview fragment with another fragment.
My problem is when I placed all my fragments into a tabhost the ArticleOnSelected no longer works, and force closes my app when ever an item is actually selected form the list view. Here is an example of one of the FC errors:

I see the problem is with the view, and I think it can not access the main framelayout from the layout which holds all the fragments with the navigation drawer.
My MainDrawer2 class is what opens first and is where the drawer and fragments are loaded into. The code is:
public class MainDrawer2 extends FragmentActivity
{
private static final String EXTRA_NAV_ITEM = "extraNavItem";
private static final String STATE_CURRENT_NAV = "stateCurrentNav";
private ActionBarDrawerToggle mDrawerToggle;
private DrawerLayout mDrawerLayout;
private NavDrawerListAdapter mDrawerAdapter;
private ListView mDrawerList;
private CharSequence mTitle;
private CharSequence mDrawerTitle;
private MainNavItem mCurrentNavItem;
public static Intent createLaunchFragmentIntent(Context context, MainNavItem navItem)

.putExtra(EXTRA_NAV_ITEM, navItem.ordinal());
}

mDrawerList = (ListView)findViewById(R.id.drawer);
getActionBar().setDisplayHomeAsUpEnabled(true);
enableHomeButtonIfRequired();
mDrawerAdapter = new NavDrawerListAdapter(getApplicationContext());
mDrawerList.setAdapter(mDrawerAdapter);
mDrawerList.setOnItemClickListener(new ListView.OnItemClickListener()
{
#Override

displayNavFragment((MainNavItem)parent.getItemAtPosition(position));

//go to search page
Fragment Fragment_one;
FragmentManager man= getSupportFragmentManager();
FragmentTransaction tran = man.beginTransaction();
Fragment_one = new Search();
tran.replace(R.id.main, Fragment_one);//tran.
tran.addToBackStack(null);
tran.commit();
}
}
The default fragment which is loaded is the fragment which holds my tabhost and creates the tabs:
public class StatisticsTab extends Fragment {
private FragmentTabHost mTabHost;
//Mandatory Constructor
public StatisticsTab() {
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_tabs,container, false);
mTabHost = (FragmentTabHost)rootView.findViewById(android.R.id.tabhost);
mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("Basic").setIndicator("Basic"),
StatisticsPage.class, null);
mTabHost.addTab(mTabHost.newTabSpec("Brewery").setIndicator("Brewery"),
BreweryStatistics.class, null);
mTabHost.addTab(mTabHost.newTabSpec("Style").setIndicator("Style"),
StyleStatistics.class, null);
mTabHost.addTab(mTabHost.newTabSpec("Taste").setIndicator("Taste"),
TasteStatisticsPage.class, null);
return rootView;
}
}
If I click on an item in my tab and bring up the listview like this:
It gives me the FC I posted above. The code for this fragment is:
public class BreweryStatistics extends Fragment implements GetBreweryStatisticsJSON.OnArticleSelectedListener {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.brewery_statistics_layout, container, false);
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getActivity());
String userName = prefs.getString("userName", null);
String userID = prefs.getString("userID", null);
String url = "myURL";
//async task to get beer taste tag percents
GetBreweryStatisticsJSON task = new GetBreweryStatisticsJSON(getActivity());
task.setOnArticleSelectedListener(this);
task.execute(url);
// Inflate the layout for this fragment
return v;
}
#Override
public void onArticleSelected(String bID){
//code to execute on click
Fragment Fragment_one;
FragmentManager man= getFragmentManager();
FragmentTransaction tran = man.beginTransaction();
Fragment_one = new BreweryPage2();
final Bundle bundle = new Bundle();
bundle.putString("breweryIDSent", bID);
Fragment_one.setArguments(bundle);
tran.replace(R.id.main, Fragment_one);//tran.
tran.addToBackStack(null);
tran.commit();
}
}
And when that onArticleSelected above is executed it does not load the new fragment. In theory what should happen the Fragment that holds the tabhost StatisticsTab should be replaced with the new Fragment in the OnArticleSelected
Right now I have it not force closing but the keyboard pops up without the search box openning up, like in this picture:
My Search Fragment activity looks like:
public class Search extends Fragment implements SearchView.OnQueryTextListener, ReadJSONResult.OnArticleSelectedListener {
private ListView lv;

//get user information
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getActivity());
String userName = prefs.getString("userName", null);
String userID = prefs.getString("userID", null);
//ActionBar actionBar = getActivity().getActionBar();
// Inflate the layout for this fragment
return v;
}
#Override
public void onCreateOptionsMenu (Menu menu, MenuInflater inflater) {
// Inflate the menu; this adds items to the action bar if it is present.
searchView = (SearchView) menu.findItem(R.id.menu_search2).getActionView();
searchView.setOnQueryTextListener(this);
searchView.setIconified(false);
}
public boolean onQueryTextSubmit (String query) {
//toast query
//make json variables to fill
// url to make request
String url = "myURL";
try {
query = URLEncoder.encode(query, "UTF-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String jsonUrl = url + query;
//todo: get json
ReadJSONResult task = new ReadJSONResult(getActivity());
task.setOnArticleSelectedListener(this);
task.execute(jsonUrl);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
// TODO Auto-generated method stub
return false;
}
#Override
public void onArticleSelected(String b, String brewery){
//code to execute on click
Fragment Fragment_one;
FragmentManager man= getFragmentManager();
FragmentTransaction tran = man.beginTransaction();
Fragment_one = new BeerPage();
final Bundle bundle = new Bundle();
bundle.putString("beerIDSent", b);
bundle.putString("breweryIDSent", brewery);
Fragment_one.setArguments(bundle);
tran.replace(R.id.main, Fragment_one);//tran.
tran.addToBackStack(null);
tran.commit();
}
}

"searchView" has not been initialized properly yet, because before you create the field, but didn't assign any view for it:
SearchView searchView;
So in your onCreateView you should find your View by Id first before calling methods of searchView:
searchView = (SearchView) findViewById(R.id.the_view_id_here);
