I was trying to go to another page using button, but it always fail.


button



Here is my First Class with its XML:


public class FindPeopleFragment extends Fragment
public FindPeopleFragment()

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)

View rootView = inflater.inflate(R.layout.fragment_home, container, false);
return rootView;


public void goToAttract(View v)

Intent intent = new Intent(getActivity().getApplication(), MainActivityList.class);
startActivity(intent);




Here is my XML:


<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerInParent="true"
android:layout_marginBottom="48dp"
android:onClick="goToAttract"
android:text="Button" /></RelativeLayout>

Intent() need an activity instance, and a class, so GetActivity() for the instance and ClassName.class for the class. Getapplication() return an instance of the Application variable.

Try this code once-


public class FindPeopleFragment extends Fragment

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
View rootView = inflater.inflate(R.layout.fragment_home,
container, false);
Button button = (Button) rootView.findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
updateDetail();

);
return rootView;


public void updateDetail()
Intent intent = new Intent(getActivity(), MainActivityList.class);
startActivity(intent);




And as suggested by Raghunandan remove below code from your fragment_home.xml-


fragment_home.xml


android:onClick="goToAttract"





your code, try to intend it correctly it does not look well

Remove this


android:onClick="goToAttract"



Then


View rootView = inflater.inflate(R.layout.fragment_home, container, false);
Button b = (Button)rootView.findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener()

public void onClick(View v)

Intent intent = new Intent(getActivity(), MainActivityList.class);
startActivity(intent);



);
return rootView;



The error says you need to public void goToAttract(View v) in Activity class


public void goToAttract(View v)


Could not find method goToAttract(View) in the activity class



Reason pls check the answer by PareshMayani @



Android app crashing (fragment and xml onclick)



Edit:


Caused by: java.lang.OutOfMemoryError



I guess you have a image that is too big to fit in and it needs to be scaled down. Hence the OutOfMemoryError.


OutOfMemoryError





are you sure that i dont need to do this "Button b = (Button) rootView.findViewById(R.id.button1);" i get error without that and after running with that i get this error link

@user3138250 yess you need to cast it to button. it was a typo error
– Raghunandan
Dec 30 '13 at 8:58





@user3138250 pls post the stack trace instead of posting links to snap shots. No way we can guess what's happenning without seeing the stacktrace. If you keep posting links i don't think i willwaste my time looking at snap shots

in your receiving intent use as


Intent intent = getActivity().getIntent();
((TextView)view.findViewById(R.id.hello)).setText(intent.getStringExtra("Hello"));



and in your send intent


Intent intent = new Intent(getActivity(),Main2Activity.class);
intent.putExtra("Hello","Nisar");
getActivity().startActivity(intent);



remember both are in fragments



You need to use getActivity() method from fragment for Intents.


Intent intent = new Intent(getActivity(), SecondActivity.class);
startActivity(intent);


FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame, new MySchedule()).commit();



MySchedule is the name of my java class.



For Kotlin you can use...


val myIntent = Intent(activity, your_destination_activity::class.java)
startActivity(myIntent)

Hystrix command on request collapser fallback

Clash Royale CLAN TAG #URR8PPP Hystrix command on request collapser fallback I have a scenario where I want to apply hystrix on the fallback (and process one-by-one) of a hystrix request collapser's batch method. The fallback method ( processEntryBatch_fallback ) is invoked. But the hystrix command ( processEntryBackup ) in turn the fallback invokes is not reported (doesn't even appear on dashboard). And the fallback method ( finalFallback ) is not invoked either. I would like to know what am I missing here ?
