Access View from Another Layout

[Qtek]

I'm using a ListView with custom list items (including a button). I have a custom adapter, in which I set the button's OnClickListener to an inner class (defined in the adapter class).I want to access the button in the class (defined in a different xml file from the ListAcitivty class's) in which the listview is displayed. I want to set it's onClickListener method inside this class. What's the best way to go about doing this? Edit: This is my list_item.xml (I use for my ListView rows). \[code\] <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" ><ImageView android:id="@+id/imageView" android:layout_width="22dp" android:layout_height="wrap_content" android:layout_marginLeft="4dp" android:layout_marginRight="10dp" android:layout_marginTop="4dp" android:contentDescription="Color" android:src="http://stackoverflow.com/questions/11381885/@drawable/ic_launcher" ></ImageView><EditText android:id="@+id/nameEdit" android:layout_width="250dp" android:layout_height="wrap_content" android:textSize="20dp" android:inputType="textPersonName" ></EditText><Button android:id="@+id/deleleButton" android:layout_width="wrap_content" android:layout_height="match_parent" android:background="@drawable/delete_button" ></Button></LinearLayout>\[/code\]How do I access the button (id:deleteButton) inside my class that extends ListActivity? The class that extends listactivity has a separate layout (main.xml let's say). If I do setContentView(main) inside the class that extends listactivity, findViewById(R.id.deleteButton) would return null.Edit 2:This is my class that extends ListActivity. If I place findViewById(R.id.deleteButton) after the setContentView it returns null.\[code\]public class PlayerSelection extends ListActivity { ListView list; ArrayList<PlayerField> textviews = null; PlayerFieldsAdapter adapter = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.player_selection_page); list = getListView(); textviews = new ArrayList<PlayerField>(); for (int i = 0; i< GlobalVariables.getPlayers(); i++) { textviews.add(i, new PlayerField()); } adapter = new PlayerFieldsAdapter(this, R.layout.list_item, textviews); ViewGroup header = (ViewGroup) getLayoutInflater().inflate(R.layout.list_header, null); Button backButton = null; for (int i = 0; i < header.getChildCount(); i++) { View v = header.getChildAt(i); if (v instanceof Button) { backButton = (Button) v; break; } } backButton.setOnClickListener(new OnClickListener() { public void onClick(View v) { Intent optionsIntent = new Intent(PlayerSelection.this, OptionsScreen.class); startActivity(optionsIntent); } }); list.addHeaderView(header); list.setAdapter(adapter); }\[/code\]
