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

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.
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);
}
});
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
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
If you can get a View
in that fragment, you can access the context from there:
view.getContext().startActivity(intent);
You need to use getActivity() method from fragment for Intents.
Intent intent = new Intent(getActivity(), SecondActivity.class);
startActivity(intent);
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"
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame, new MySchedule()).commit();
MySchedule is the name of my java class.
use getContext() instead of MainActivity.this
Intent intent = new Intent(getContext(), SecondActivity.class);
startActivity(start);
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
.
For Kotlin you can use
val myIntent = Intent(activity, your_destination_activity::class.java)
startActivity(myIntent)
