Hi, Why we pass "this" to the first parameter of the Intent object and not this.MainActivity?, the context is our MainActivity so why not add the name of the file? I understand that "this" refer to the current activity but i want to know if they both valid.
instead of :
Intent intent = new Intent(this, StoryActivity.class);
we should use:
Intent intent = new Intent(MainActivity.this, StoryActivity.class);

However, if you move all the code from the startStory() method to the onClick() method in the anonymous OnClickListener inner class, you would need to call MainActivity.this, as you would now be in an inner class.
startButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String name = nameField.getText().toString();
Intent intent = new Intent(MainActivity.this, StoryActivity.class);
Resources resources = getResources();
String key = resources.getString(R.string.key_name);
intent.putExtra(key, name);
startActivity(intent);
}
});
I hope that makes sense :)

17,036 PointsLauren Moineau Thanks for the answer! :D I understand that so i only would call MainActivity.this if its in the onClick method, if its on its own method i would call this?
