    copied!<p>I would have listview and a lot of items inside. I want that user can long press on item and set it as Favorite. To do that, I need to get DB id to this menu on long press.</p> <p>I have the following code</p> <pre><code>@Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); menu.setHeaderTitle("Favorite"); menu.add(0, REMOVE_TODO, Menu.NONE, R.string.favorit_add); } </code></pre> <p>It works just fine... But what I want to do is to get text and database id of selected item. </p> <p>So insetead of "Favorite" I would like to write Favorite: Item1.</p> <p>If anyoune could help I would be thankful. </p> <p>Here is a code for my adapter... I actually used example's adapter.</p> <pre><code> package com.TVSpored; import android.content.Context; import java.util.*; import android.view.*; import android.widget.*; public class ToDoItemAdapter extends ArrayAdapter&lt;ToDoItem&gt; { int resource; public ToDoItemAdapter(Context _context, int _resource, List&lt;ToDoItem&gt; _items) { super(_context, _resource, _items); resource = _resource; } @Override public View getView(int position, View convertView, ViewGroup parent) { LinearLayout todoView; ToDoItem item = getItem(position); String taskString = item.getTask(); String icon_name = item.getCreated(); int fav = item.getFavorite(); if (convertView == null) { todoView = new LinearLayout(getContext()); String inflater = Context.LAYOUT_INFLATER_SERVICE; LayoutInflater vi = (LayoutInflater)getContext().getSystemService(inflater); vi.inflate(resource, todoView, true); } else { todoView = (LinearLayout) convertView; } ImageView favView = (ImageView)todoView.findViewById(R.id.rowImgFav); ImageView channelView = (ImageView)todoView.findViewById(R.id.rowImg); TextView channelName = (TextView)todoView.findViewById(R.id.row); //dateView.setText(dateString); channelView.setImageResource(getContext().getResources().getIdentifier("com.TVSpored:drawable/channels_"+icon_name , null, null)); channelName.setText(taskString); if(fav == 0) { favView.setImageResource(R.drawable.sys_srcek_disabled); } else { favView.setImageResource(R.drawable.sys_srcek); } return todoView; } } </code></pre> <p>And furtherer my Item</p> <pre><code>package com.TVSpored; import java.text.SimpleDateFormat; public class ToDoItem { String task; String created; Integer fav; Integer id; public String getTask() { return task; } public String getCreated() { return created; } public Integer getFavorite() { return fav; } public Integer getID() { return id; } public ToDoItem(String _task, String _created, int _fav, int _id) { task = _task; created = _created; fav = _fav; id = _id; } } </code></pre> <p>Here is a code in main activity class</p> <pre><code> @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); menu.setHeaderTitle("Urejanje kanala"); menu.add(0, REMOVE_TODO, Menu.NONE, R.string.favorit_add); // static final private int REMOVE_TODO = Menu.FIRST + 1; // defined ad the begining } @Override public boolean onOptionsItemSelected(MenuItem item) { super.onOptionsItemSelected(item); AdapterContextMenuInfo menuInfo = (AdapterContextMenuInfo) item.getMenuInfo(); int arrayAdapterPosition = menuInfo.position; ToDoItem todoItem = (ToDoItem)aa.getItem(arrayAdapterPosition); String task = todoItem.getTask(); int id = todoItem.getID(); int index = myListView.getSelectedItemPosition(); aa.getItemId(index); changeFavorite(id); return true; } </code></pre> <p>Here is updateArray function (called on change)</p> <pre><code>private void updateArray() { toDoListCursor.requery(); todoItems.clear(); int j = 0; if (toDoListCursor.moveToFirst()) do { String task = toDoListCursor.getString(toDoListCursor.getColumnIndex(ToDoDBAdapter.KEY_NAME)); String created = toDoListCursor.getString(toDoListCursor.getColumnIndex(ToDoDBAdapter.KEY_EPG_NAME)); int fav = toDoListCursor.getInt(toDoListCursor.getColumnIndex(ToDoDBAdapter.KEY_EPG_NAME)); int id = toDoListCursor.getInt(toDoListCursor.getColumnIndex(ToDoDBAdapter.KEY_ID)); ToDoItem newItem = new ToDoItem(task, created, fav, id); todoItems.add(0, newItem); j++; } while(toDoListCursor.moveToNext()); aa.notifyDataSetChanged(); } </code></pre> <p>and a populate function... </p> <pre><code>private void populateTChannels() { // Get all the todo list items from the database. toDoListCursor = toDoDBAdapter. getAllToDoItemsCursor(); if((toDoListCursor.getCount() == 0) || !toDoListCursor.moveToFirst()) { toDoDBAdapter.populateDB(); } if(toDoDBAdapter.ChannelsArray.length &gt; toDoListCursor.getCount()) { toDoDBAdapter.populateDBWhitCheck(); } toDoListCursor = toDoDBAdapter. getAllToDoItemsCursor(); startManagingCursor(toDoListCursor); // Update the array. updateArray(); } </code></pre>
