Cómo llamar a un fragmento de BaseAdapter Class Android?

Quiero llamar a un fragmento de mi clase BaseAdapter. En esta clase tengo un botón de clic del que quiero llamar al nuevo fragmento, pero no puedo conseguirlo. Tengo que pasar valores del clic del botón al fragmento.

Clase BaseAdapter

• Intentos pendientes no disparados
• Inicie la aplicación google maps para obtener instrucciones sobre cómo llegar en android
• Valores perdidos en la actividad anterior cuando hago clic en el botón, pero no cuando this.finish () se llama
• ¿Cómo puedo enlazar este servicio en Android?
• Acceso directo para iniciar una actividad

public class StatusAdapter extends BaseAdapter { private Activity activity; private ArrayList<HashMap<String, String>> data; private static LayoutInflater inflater = null; public StatusAdapter(Activity a, ArrayList<HashMap<String, String>> d) { activity = a; data = d; inflater = (LayoutInflater) activity .getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public int getCount() { // TODO Auto-generated method stub return data.size(); } @Override public Object getItem(int position) { // TODO Auto-generated method stub return position; } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { View vi = convertView; if (convertView == null) vi = inflater.inflate(R.layout.approval_selftrip_inner, null); TextView approved_by = (TextView) vi.findViewById(R.id.approved_by); TextView status = (TextView) vi.findViewById(R.id.status); TextView trip = (TextView) vi.findViewById(R.id.trip); Button view_log = (Button)vi.findViewById(R.id.view_log); HashMap<String, String> list = new HashMap<String, String>(); list = data.get(position); approved_by.setText(list.get("first_id")); status.setText(list.get("status")); trip.setText(list.get("trip")); view_log.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { //Here i want to call my fragment } }); return vi; } } 

Fragmento

 public class Log extends Fragment { Context context ; View rootView; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { context = getActivity(); rootView = inflater.inflate(R.layout.activity_log, container, false); return rootView; } } 

Quiero llamar a este fragmento de la clase BaseAdapter en el clic de view_log . view_log favor, ayúdame cómo podemos hacer esto

Después de Martin Cazares he hecho esto

En Actividad

 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { context = getActivity(); rootView = inflater.inflate(R.layout.activity_main, container, false); mBroadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { Toast.makeText(context, "Recived", Toast.LENGTH_LONG).show(); ApprovalLog fragment2 = new ApprovalLog(); FragmentManager fragmentManager = getFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager .beginTransaction(); fragmentTransaction.replace(R.id.content_frame, fragment2); fragmentTransaction.commit(); } }; return rootView; } 

En la clase AdapterClass

 view_approvallog.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { CommonUtils.showAlert("Test in Adapter", activity); activity.registerReceiver(mBroadcastReceiver, new IntentFilter( "start.fragment.action")); } }); 

 public void onClick(View view) { LogFrag fragment2 = new LogFrag(); FragmentManager fragmentManager = getFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); fragmentTransaction.replace(R.id.fragment1, fragment2); fragmentTransaction.commit(); } 

  view_log.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { //Here i want to call my fragment //You need to pass a reference of the context to your adapter... context.sendBroadcast(new Intent("start.fragment.action")) } }); 

 //In your activity... context.registerReceiver(mBroadcastReceiver, new IntentFilter("start.fragment.action")) . . . BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { //This piece of code will be executed when you click on your item // Call your fragment... } }; 

 ((Activity) mContext).getFragmentManager();//use this view.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Fragment fragment = new CallThisFragment(); FragmentManager fragmentManager = ((Activity) mContext).getFragmentManager(); fragmentManager.beginTransaction().replace(R.id.main_activity, fragment).commit(); } }); 

 Adapter a = new Adapter(arg,Fragment.this);// or only this. This will pass the fragment object to the adapter. 

 v.ckbox.setOnCheckedChangeListener(new OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if(fragment!=null) fragment.ValidateList();// call any public method of the fragment } }); 

 fragmentManager.beginTransaction() .add(R.id.content_frame, new YourFragmentName()) .addToBackStack("fragBack")).commit(); ((Activity) context).setTitle("Title For Action Bar");`
