So fügen Sie Aktivitäten zu Fragment Android hinzu ⇐ Android

[Anonymous]

Dies ist ein Beispiel meines Codes. Ich möchte eine neue Anwendung erstellen und Code aus meinem vorherigen Projekt kopieren, erhalte jedoch eine Fehlermeldung.
HomeFragment.java (aus dem Sliding Menu)

Code: Select all

package com.example.sia;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class HomeFragment extends Fragment {

public HomeFragment(){}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

View rootView = inflater.inflate(R.layout.fragment_home, container, false);

return rootView;
}
}

Account.java

Code: Select all

package com.example.sia2;

import java.util.HashMap;

import org.json.JSONArray;
import android.os.Bundle;
import android.app.Activity;
import android.text.Html;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class Account extends Activity {

Button logout;
SessionManager session;
TextView status;
JSONArray contacts = null;
String nim, name;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_account);

session = new SessionManager(getApplicationContext());
Toast.makeText(getApplicationContext(),
"User Login Status: " + session.isLoggedIn(), Toast.LENGTH_LONG)
.show();

session.checkLogin();

HashMap user = session.getUserDetails();

name = user.get(SessionManager.KEY_NAME);
// id = user.get(SessionManager.KEY_ID);

TextView status = (TextView) findViewById(R.id.status);
status.setText(Html.fromHtml("Welcome," + name + "[/b]  "));[b]
logout = (Button) findViewById(R.id.logout);

logout.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
session.logoutUser();
finish();
}
});
}

}

Ich kombiniere den Code

Code: Select all

package com.example.sia;

import java.util.HashMap;

import org.json.JSONArray;

import com.example.sia.R;
import com.example.sia.SessionManager;

import android.app.Fragment;
import android.os.Bundle;
import android.text.Html;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class HomeFragment extends Fragment {

Button logout;
SessionManager session;
TextView status;
JSONArray contacts = null;
String nim, name;

public HomeFragment(){}

@Override
/**public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_account);**/

public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

View rootView = inflater.inflate(R.layout.fragment_home, container, false);

session = new SessionManager(getActivity().getApplicationContext());
Toast.makeText(getActivity().getApplicationContext(),"User Login Status: " + session.isLoggedIn(), Toast.LENGTH_LONG).show();

session.checkLogin();

HashMap user = session.getUserDetails();

name = user.get(SessionManager.KEY_NAME);
// id = user.get(SessionManager.KEY_ID);

TextView status = (TextView) getView().findViewById(R.id.status);
status.setText(Html.fromHtml("Welcome," + name + "[/b]  "));

logout = (Button) getView().findViewById(R.id.logout);

logout.setOnClickListener(new View.OnClickListener()
{

@Override
public void onClick(View arg0)
{
// TODO Auto-generated method stub
session.logoutUser();
getActivity().finish();
}

});
return rootView;
}

}
/*public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

View rootView = inflater.inflate(R.layout.fragment_home, container, false);

return rootView;
}*/

Ich kann die Anwendung starten, aber wenn ich fragment_home.xml öffne, reagiert sie nicht

Vielen Dank
