public class MainActivity extends AppCompatActivity implements
TopSectionFragment.TopSectionListener {
When I try to implement the TopSectionFragment the writing goes red and, then it says Cannot resolve symbol when my mouse goes over it.
This is all happening in Android Studio.
My MainActivity.java looks like this:
package com.example.danielhunter.fragments;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;`
public class MainActivity extends AppCompatActivity
implements TopSectionFragment.TopSectionListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
My TopSectionFragment.java looks liks this:
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.view.ViewGroup;
import android.view.View;
import android.view.LayoutInflater;
import android.support.v4.app.Fragment;
import android.widget.Button;
import android.widget.EditText;
import android.app.Activity;
import com.example.danielhunter.fragments.R;
public class TopSectionFragment extends Fragment {
private static EditText topTextInput;
private static EditText bottomTextInput;
TopSectionListener activityCommander;
public interface TopSectionListener{
public void createMeme(String top,String bottom);
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try{
activityCommander = (TopSectionListener) activity;
}catch (ClassCastException e){
throw new ClassCastException(activity.toString());
}
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.top_section_fragment, container, false);
topTextInput = (EditText) view.findViewById(R.id.topTextInput);
bottomTextInput = (EditText) view.findViewById(R.id.bottomTextInput);
final Button button = (Button) view.findViewById(R.id.button);
button.setOnClickListener(
new View.OnClickListener(){
public void onClick(View v){
buttonClicked(v);
}
}
);
return view;
}
// calls this when the button is clicked
public void buttonClicked(View view){
activityCommander.createMeme(topTextInput.getText().toString(), bottomTextInput.getText().toString());
}
}
