I'm following a tutorial I found on this website http://www.helloandroid.com/tutorials/using-facebook-sdk-android-development-part-2 and when I inserted the 2 sets of code segments in the classes the tutorial specifies I get 4 facebook sdk related errors. I inserted to the code segments bellow with the errors bold/starred.
Does anyone have any idea how I can fix these errors?
Here are the error messages i get when i mouse over the errors, in order:
1.onCreate(Bundle savedInstanceState) : The method onCreate(Bundle) of type main must override or implement a supertype method
btnLogin.setOnClickListener(new OnClickListener() : OnClickListener cannot be resolved to a type
LoginDialogListener : The type FBConnectionActivity.LoginDialogListener must implement the inherited abstract method Facebook.DialogListener.onComplete(Bundle)
onComplete(Bundle values) : The method onComplete(Bundle) of type FBConnectionActivity.LoginDialogListener must override or implement a supertype method
Segment 1 (2 errors) : In this part the errors are at the oncreate and the onclicklistener
package com.outfit.first;
import android.widget.Button;
import android.widget.ProgressBar;
import android.widget.TextView;
public class main extends FBConnectionActivity {
private TextView txtUserName;
private ProgressBar pbLogin;
private Button btnLogin;
@Override
public void **onCreate(Bundle savedInstanceState)** {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
txtUserName = (TextView) findViewById(R.id.textFacebook);
pbLogin = (ProgressBar) findViewById(R.id.progressLogin);
btnLogin = (Button) findViewById(R.id.buttonLogin);
btnLogin.setOnClickListener(new **OnClickListener**() {
@Override
public void onClick(View arg0) {
pbLogin.setVisibility(ProgressBar.VISIBLE);
setConnection();
getID(txtUserName, pbLogin);
}
});
}
}
Segment 2 (2 errors): In this part the errors are at the LoginDialogListener class and the onComplete(Bundle values) inside that class.
