I am pretty new to the Google Maps API v2 and would like to integrate a map available via this base link: https://tiles.guildwars2.com/{continent_id}/{floor}/{zoom}/{x}/{y}.jpg. My problem is, well everything, but let's get started with the following:
1) How can I set the map sizes that there is no grey space at any side?
2) How can I move the map correctly because I have obviously 4 parameters while I can change only 3 at a time with getTileUrl?
3) Why are the tiles mixed and not shown in their correct order?
The map documentation is available here:

Ok, after having a looooong break because of school I figured everything out except the first thing.
My fault with the wrong tiles was that I did not have the correct order of params.
The other thing with the to much params, I will program myself a workaround in the near future.
So I will close the thread and open a new one just before I smash the display because sth doesn't work.

try change your code inside onNavigationItemSelected to this:
switch (item.getItemId()){
case R.id.nav_alarm:
//do stuff
Intent goToNextActivity = new Intent(getApplicationContext(), Main2Activity.class);
startActivity(goToNextActivity);
break;
}
FragmentTransaction ft =getSupportFragmentManager().beginTransaction();
ft.replace(R.id.content_main,fragment);
ft.addToBackStack(null);
ft.commit();
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
You should check your onNavigationItemSelected(MenuItem item) method because while replacing the fragment you initailized you fragment null like Fragment fragment = null; .So, for replace the fragment you need to take actual fragment instead of null fragmnet.
You may go through about the fragments here.
`
Change the flow of the code as below:
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
item.setCheckable(false);
Fragment fragment=null;
switch (item.getItemId()) {
case R.id.navigation_home:
fragment = new HomeFragment();
break
}
loadHomeFragment(fragment);
mDrawerLayout.closeDrawer(GravityCompat.START);
return true;
}
private void loadHomeFragment(Fragment fragment) {
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.setCustomAnimations(android.R.anim.fade_in,
android.R.anim.fade_out);
fragmentTransaction.replace(R.id.frame, fragment);
fragmentTransaction.commitAllowingStateLoss();
}

Closed 6 years ago.
I am currently trying to program a small app, now I am trying to use a Navigation Drawer in my app. This does not work with the reason that I get a NPE at drawer.addDrawerListener(toggle);. Everything else seems to be fine as far as I can say and the app worked correctly till adding the drawer. Thx in advance.

First change this part
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
toolbar = (Toolbar) findViewById(R.id.toolbar);
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
navigationView = (NavigationView) findViewById(R.id.nav_view);
setSupportActionBar(toolbar);
setContentView(R.layout.activity_main);
to this
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
navigationView = (NavigationView) findViewById(R.id.nav_view);
setSupportActionBar(toolbar);
Because you are not set layout to Actiivty before that you have to access it inner element so that the Studio can't find it and it give you NullpointerExeception.

Here is one of my fragment :
import android.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.asd.k4c.R;
public class SearchCoachingFragment extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootview = inflater.inflate(R.layout.fragment_search_coaching,container,false);
return rootview;
}
} //Update code formatting
Suppose I want to call resultsfragment from the above fragment on the click
of a button whose id is btn_search, then what should I do?
I tried some already existing answers here, no luck!
P.S: I'm a starter to the world of android dev.
For doing a fragment transaction.Please do the following.
Eg..
A and B are fragments.
Currently A is visible to the User. If you want to do a transaction.
Just create as like below
B b = new B();
((YourActivity)getActivity).setnewFragment(b,true);
public void setNewFragment(Fragment fragment,boolean addbackstack) {
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.fragment_content, fragment);
if (addbackstack)
transaction.addToBackStack(title);
transaction.commit();
}
Use an interface to communicate between fragments. For example
public YourFirstFragment extends Fragment {
public interface FragmentCallBack {
void callBack();
}
private FragmentCallBack fragmentCallBack;
public void setFragmentCallBack(FragmentCallBack fragmentCallBack) {
this.fragmentCallBack = fragmentCallBack;
}
private void callThisWhenYouWantToCallTheOtherFragment(){
fragmentCallBack.callBack();
}
}
Then in You activity
private void setCallToFragment{
yourFirstFragment.setFragmentCallBack(new FragmentCallBack(){
void callBack(){
yourSecondFragment.doWhatEver();
}})
}
First you need to create an interface which defines methods that will be used by your fragment to invoke code from the respective activity it is attached to
public interface OnFragmentInteractionlistener {
// the method that you call from your fragment,
// add whatever parameter you need in the implementation of this
// method.
void onClickOfMyView();
}
once you have created the interface, implement it any and all activities that use this fragment.
public class MainActivity extends AppCompatActivity
implements OnMyFragmentInteractionListener {
#Override
public void onClickOfMyView() {
// DO your on click logic here, like starting the transaction
// to add/replace another fragment.
}
}
Then in the onAttach of your fragment to an activity be sure to check if the attaching activity implements this interface, else throw a RunTimeException like so
#Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof OnMyFragmentInteractionListener) {
mListener = (OnMyFragmentInteractionListener) context;
} else {
throw new RuntimeException(context.toString()
+ " must implement OnMyFragmentInteractionListener");
}
}
Here mListener is a interface reference you hold in your fragment class through which you invoke the onClickOfMyView() method when actually the click happens
Your fragment class where the view's click code is there.
myView.setOnClickListener(new View.OnClickListener(){

You should create some method in your activity. Supposedly it will look like this :
public void startFragment(Fragment fragment) {
fm.beginTransaction().replace(R.id.content_frame,new fragment).commit();
}
As you already done in youronNavigationItemSelected
Then, from your fragment, you can call
((MainActivity)getActivity()).startFragment(new SearchConsultanciesFragment())
for example
Create a method switchFragment in your MainActivity
FragmentTransaction ft;
public void switchFrag() {
try {
ft = getActivity().getFragmentManager().beginTransaction();
ft.replace(R.id.frame_container, new Your_Fragment.class);
ft.commit();
} else {
Log.e("test", "else part fragment ");
}
} catch (Exception e) {
e.printStackTrace();
}
}
Now from your current Fragment you can call this MainActivity's funciton throught the below code:
((MainActivity)getActivity()).switchFrag();
Let me know if this works for you! :)
I have a navigation drawer that when an Item is selected, it loads the new fragment but never closes the drawer. My navigation drawer code looks like this:

Add this to your onItemClick method of the mDrawerList
if(mDrawerLayout.isDrawerOpen(mDrawerList)) {

I can't find where are you loading fragment in your code but you are probably missing mDrawerToggle.onDrawerClosed(mDrawerLayout); before you replace your fragments.
I currently have a menu that I load into my Toolbar which looks like this:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_search"
android:icon="#android:drawable/ic_menu_search"
app:showAsAction="always|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"
android:onClick="goToSearch"
android:title="Search"/>
<item android:id="#+id/action_barcode"
android:icon="#drawable/bar"
android:title="barcode"
app:showAsAction="ifRoom"
android:onClick="scanBarcode"/>
</menu>
When you click the barcode icon, it loads my barcode scanning fragment. I want to clean up my toolBar and not have multiple icons up there. Essentially I want my search icon, that opens up when clicked to have two functions.
When clicked open the search bar.
When long pressed, open my barcode scan fragment.
Currently Number one works, looking at how to employ number 2.
This is what my code looks liek for launching the barcode scan fragment and search.

The action bar concept doesn't count on this requirement, so using built-in functionality you'll never be able to achieve what you need.
You can, however, introduce your own custom layout in stock action bar and do whatever you want there. See an example here:
