Android Intent Cannot resolve constructor
AndroidAndroid IntentAndroid Problem Overview
I have a first class extending Fragment, and a second class extending Activity.
My Fragment is working fine, and my code for the Intent in the Fragment is :
ImageButton button= (ImageButton) getView().findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent myIntent = new Intent(MyFragment.this, MyClass.class);
MyFragment.this.startActivity(myIntent); }
});
My class MyClass code is :
public class MyClass extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// The activity is being created.
}
@Override
protected void onStart() {
super.onStart();
setContentView(R.layout.MyClass);
}
}
The error is :
Gradle: cannot find symbol constructor Intent(com.xxxx.xxxx.MyFragment,java.lang.Class<com.xxxx.xxxx.MyClass>)
I don't know where I went wrong.

Solution 1 - Android
Use
Intent myIntent = new Intent(v.getContext(), MyClass.class);
or
Intent myIntent = new Intent(MyFragment.this.getActivity(), MyClass.class);
to start a new Activity. This is because you will need to pass Application or component context as a first parameter to the Intent Constructor when you are creating an Intent for a specific component of your application.
Solution 2 - Android
Or you can simply start the activity as shown below;
startActivity( new Intent(currentactivity.this, Tostartactivity.class));
Solution 3 - Android
You may use this:
Intent intent = new Intent(getApplicationContext(), ClassName.class);
Solution 4 - Android
> Using .getActivity()
solves this issue:
For eg.
Intent i= new Intent(MainActivity.this.getActivity(), Next.class);
startActivity(i);
Hope this helps.
Cheers.

You Can not Use the Intent's Context
for Creating Intent. So You need to use your Fragment's
Parent Activity
Context
Intent intent = new Intent(getActivity(),MyClass.class);
Solution 6 - Android
Same Error was coming with my code in Activity but not in Fragment. Showing constructor error for different line like new Intent( From.this, To.class) and new ArrayList<> etc.
Fixed using closing Android Studio and moving the repository to other location and opening the the project once again. Fixed the problem.
Seems like Android Studio building problem.

this work for me
ncharacters.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent openncharacter = new Intent(getApplicationContext(),ncharacters.class);
startActivity(openncharacter);
}
});
