I'm trying to handle the back button in a fragment. I want it to go back to the fragment it came from, but the #Override I've doesn't override from its superclass, but I don't why. Futhermore the method onBackPressed() is never used. I think it's weird as it works in my activities.
public class RateFrag extends Fragment implements View.OnClickListener {
private RatingBar ratingBar;
private Button rateknap;
private Forslag forslag;
#Override
public View onCreateView(LayoutInflater i, ViewGroup container, Bundle savedInstanceState) {
View rod = i.inflate(R.layout.activity_rate, container, false);
setHasOptionsMenu(true);
forslag = ((AnnonceDisplay) this.getActivity()).getForslag();
getActivity().setTitle(forslag.getTitle());
ratingBar = (RatingBar) rod.findViewById(R.id.ratingBar);
rateknap = (Button) rod.findViewById(R.id.rateknap);
rateknap.setOnClickListener(this);
return rod;
}
#Override
public void onClick(View v) {
if (v == rateknap) {
AlertDialog alert = new AlertDialog.Builder(getActivity())
.setMessage("Vil du give " + ratingBar.getRating() + " stjerner?")
.setPositiveButton("Ja", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
launchintent();
}
}
)
.setNegativeButton("Nej", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
}
).show();
}
}
private void launchintent() {
FragmentManager fm = getFragmentManager();
Fragment f = fm.findFragmentById(R.id.fragment);
if(fm.getBackStackEntryCount() > 0){
fm.popBackStack();
} else{
getActivity().finish();
}
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_main, menu);
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.Forside) {
Intent intent = new Intent(this.getActivity(), Forside.class);
startActivity(intent);
}
else if (id == R.id.Logud){
Intent intent = new Intent(this.getActivity(), LogInd.class);
startActivity(intent);
}
return true;
}
#Override //Method does not override method from its superclass
public void onBackPressed() { //Method onBackPressed is never used
if (getFragmentManager().getBackStackEntryCount() == 0) {
getActivity().finish();
} else {
getFragmentManager().popBackStack();
}
return;
}
}
Before anyone says it's a possible duplicate, I've searched here on Stackoverflow and Google. I actually got this Override from here, so please tell me what is wrong, and how I fix it.
Thanks :)
Override the onBackPress on your Activity like this
#Override
public void onBackPressed() {
int count = getFragmentManager().getBackStackEntryCount();
if (count == 0) {
super.onBackPressed();
} else {
getFragmentManager().popBackStack();
}
}

Here in ProductFragment iam going to add values to text view. When i was coming from ReportFragment the view values are going to be cleared in ProductFragment.
I would consider doing that in two steps:
save fragment instance instead of re-creating a new one every time
private ProductFragment productFragment;
private ReportsFragment reportsFragment;
private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener = new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.nav_home:
if(productFragment == null)
productFragment = new ProductFragment();
loadFragment(productFragment);
break;
case R.id.nav_profile:
if(reportsFragment == null)
reportsFragment = new ReportsFragment();
loadFragment(reportsFragment);
break;
case R.id.nav_logout:
LogOut();
return true;
}
return true;
}
};
referring to this question/answer, you should implement in your fragment both void onSaveInstanceState(final Bundle outState) and void onActivityCreated(Bundle savedInstanceState)
In that way you will surely keep the instance of your fragment instead of creating a new one every time (new MyFragment() will always re-create it). In addition, saving your views state in onSaveInstanceState and restoring it in your onActivityCreate, will allow you to keep your views/values.
I wrote that by hand without a compiler, so it might not be perfect.
let me know if you need further information.
Good luck
I am using this solution and it works for me.
You should see my detailed answer to a similar question. I hope it will solve your problem.
I have an Android app with a navigation drawer with menu items.This menu contains entry to multiple fragments. One of the fragments has a listview in it with names of websites. My aim is that whenever a name of website is clicked from that list the link associated with the listview item saved in stringarray in strings.xml file is opened in new fragment with webview which opens the site.
So far I have implemented this code for the fragment with listview
class AtlasListFragment extends android.support.v4.app.ListFragment implements AdapterView.OnItemClickListener {
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.atlas_list_fragment, container, false);
return view;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
ArrayAdapter adapter = ArrayAdapter.createFromResource(getActivity(),
R.array.tut_titles, android.R.layout.simple_list_item_1);
setListAdapter(adapter);
getListView().setOnItemClickListener(this);
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,long id) {
Toast.makeText(getActivity(), "Item: " + position, Toast.LENGTH_SHORT).show();
}}
And the code which launches the fragment from navigation drawer is below
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
android.support.v4.app.Fragment fragment = null;
if (id == R.id.home) {
fragment = frag;
else if (id == R.id.settings) {
fragment=new Settings();
} else if (id == R.id.about_us) {
fragment=new AboutUc();
}
else if(id == R.id.atlas){
fragment = new AtlasListFragment();
}
else{
}
if (fragment!=null)
{
FragmentManager fragmentManager=getSupportFragmentManager();
FragmentTransaction ft=fragmentManager.beginTransaction();
ft.replace(R.id.fragmentview,fragment);
ft.commit();
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
By this mehod you can open a webview in where you want use WebView layout and use this method in your activity
public void openWebView(String url){
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
}
Hope it works for you
First of all you will need broadcast so you can send your clicked
URL from adapter to your fragment, and in your main fragment when you
receive the url you can use intent or webview
1- CREATE BroadcastHelper CLASS :
public class BroadcastHelper {
public static final String BROADCAST_EXTRA_METHOD_NAME = "INPUT_METHOD_CHANGED";
public static final String ACTION_NAME = "hassan.hossam";
private static final String UPDATE_LOCATION_METHOD = "updateLocation";
public static void sendInform(Context context, String method) {
Intent intent = new Intent();
intent.setAction(ACTION_NAME);
intent.putExtra(BROADCAST_EXTRA_METHOD_NAME, method);
try {
context.sendBroadcast(intent);
} catch (Exception e) {
e.printStackTrace();
}
}
public static void sendInform(Context context, String method, Intent intent) {
intent.setAction(ACTION_NAME);
intent.putExtra(BROADCAST_EXTRA_METHOD_NAME, method);
try {
context.sendBroadcast(intent);
} catch (Exception e) {
e.printStackTrace();
}
}
}
2- Send intent from your adapter
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent url = new Intent("url");
url ("url_adapter",item.get(position).getURL());
BroadcastHelper.sendInform(context,"url",url);
}
});
3- in your fragment this use :
Receiver receiver;
boolean isReciverRegistered = false;
#Override
public void onResume() {
super.onResume();
if (receiver == null) {
receiver = new Receiver();
IntentFilter filter = new IntentFilter(BroadcastHelper.ACTION_NAME);
getActivity().registerReceiver(receiver, filter);
isReciverRegistered = true;
}
}
#Override
public void onDestroy() {
if (isReciverRegistered) {
if (receiver != null)
getActivity().unregisterReceiver(receiver);
}
super.onDestroy();
}
private class Receiver extends BroadcastReceiver {
#Override
public void onReceive(Context arg0, Intent arg1) {
Log.v("r", "receive " + arg1.getStringExtra(BroadcastHelper.BROADCAST_EXTRA_METHOD_NAME));
String methodName = arg1.getStringExtra(BroadcastHelper.BROADCAST_EXTRA_METHOD_NAME);
if (methodName != null && methodName.length() > 0) {
Log.v("receive", methodName);
switch (methodName) {
case "url":
String url_adapter = arg1.getStringExtra("url_adapter");
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url_adapter));
startActivity(i);
break;
default:
break;
}
}
}
}
i hope this helped

What has to be changed to solve this and what more has to be changed to covert it into a Fragment. I am beginner so detailed help would be appreciated.
Thanks
Method signature in fragment should be as below
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
The problem is with the return type of the method, make it void and error will be gone as the super-type returns void.
I actually have an aplication with multiple activitys (on for each icon of my toolbar), also I would like to have the possibility to show the last fragment of these activitys from the stack if the user already open it before.
As you can see in my BaseActivity class below (which I extend for all my activitys), I already add fragments to the stack.
This is my class :
public class BaseActivity extends AppCompatActivity {
private final String TAG = "BaseActivity";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_base);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
return false;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}

You can get current fragment(last one added) in the FrameLayout using:
Fragment fragment = getSupportFragmentManager().findFragmentById(layoutId); //layoutId is id of FrameLayout

.setPositiveButton("Yes", new DialogInterface.OnClickListener() {

It takes the app two back presses (and two confirmations) to exit. What explains this behaviour and is there any way to resolve this?
Remove below snippet from onBackPress() Method. It will handle by SlideMenu only.
if (menu.isMenuShowing()) {
menu.showContent();
}
Code from SlidingFragmentActivity call onBackPress:
#Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
boolean b = mHelper.onKeyUp(keyCode, event);
if (b) return b;
return super.onKeyUp(keyCode, event);
}
mHelper.onKeyUp(keyCode, event) will call a Method of SlidingActivityHelper:
public boolean onKeyUp(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK && mSlidingMenu.isMenuShowing()) {
showContent(); //Close the SlidingMenu and show the content view.
return true;
}
return false;
}
super.onBackPressed(); will do what ever you want,just include super.onBackPressed(); instead of System.exit(0);,because it will call the onBackpressed method of Activity.So,onDestroy method get call properly.
new AlertDialog.Builder(this).setIcon(android.R.drawable.ic_dialog_alert).setTitle("Exit")
.setMessage("Are you sure you want to exit?")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
finish();
super.onBackPressed();
}
}).setNegativeButton("No", null).show();
