Intent from Fragment to Activity

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

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>

Here is my stacktrace..this is the result when i used onclicklistener

You can use any of these:

Intent i = new Intent(getActivity().getApplication(),SecondActivity.class);

or

Intent i = new Intent(getActivity(),SecondActivity.class);

use getContext() instead of MainActivity.this

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

For Kotlin you can use

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

public class OneWayFragment extends Fragment {

    ImageView img_search;


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


        View view = inflater.inflate(R.layout.one_way_fragment, container, false);
        img_search = (ImageView) view.findViewById(R.id.search);


        img_search.setOnClickListener(new View.OnClickListener() {
            @Override`enter code here`
            public void onClick(View v) {
                Intent displayFlights = new Intent(getActivity(), SelectFlight.class);
                startActivity(displayFlights);
            }
        });

If you can get a View in that fragment, you can access the context from there:

view.getContext().startActivity(intent);

Hope this code will help

public class ThisFragment extends Fragment {

public Button button = null;
Intent intent;

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

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

    intent = new Intent(getActivity(), GoToThisActivity.class);
    button = (Button) rootView.findViewById(R.id.theButtonid);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            startActivity(intent);
        }
    });
    return rootView;
}

You can use this code, make sure you change "ThisFragment" as your fragment name, "yourlayout" as the layout name, "GoToThisActivity" change it to which activity do you want and then "theButtonid" change it with your button id you used.

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

MySchedule is the name of my java class.

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

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

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

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-

android:onClick="goToAttract"

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

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.

use this 

public void goToAttract(View v)
{
    Intent intent = new Intent(getActivity(), MainActivityList.class);
    startActivity(intent);
}

be sure you've registered MainActivityList in you Manifest
