Intent from Fragment to Activity

Question

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

Answer 1

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

Answer 2

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"

Answer 3

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 .

Answer 4

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

Answer 5

use getContext() instead of MainActivity.this

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

Answer 6

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.

Answer 7

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

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

Answer 8

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

MySchedule is the name of my java class.

Answer 9

For Kotlin you can use

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

Answer 10

如果您可以在该片段中获得一个View ，则可以从那里访问上下文：

view.getContext().startActivity(intent);

Answer 11

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);
            }
        });

Answer 12

You can use any of these:

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

or

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