onItemClickListener不適用於customListadapter ..有人可以幫助我。這裏是完整的代碼。我已經爲listview的itemclick監聽器設置了。但它不起作用。onItemClickListener不適用於customListadapter
輸入代碼here`BuddiesActivity.class
public class BuddiesActivity extends Activity {
/**
* list view
*/
ListView listViewFriendsDetails;
/**
* adapter for list out the friendsDetails
*/
ListViewCustomeAdapter detailsAdapter;
@Override
public boolean onCreatePanelMenu(int featureId, Menu menu) {
MenuInflater inflaterObject = getMenuInflater();
inflaterObject.inflate(R.menu.buddiesmenu, menu);
/*
* to change the colour of menu background
*/
getLayoutInflater().setFactory(new Factory() {
@Override
public View onCreateView(String name, Context context,
AttributeSet attrs) {
if (name.equalsIgnoreCase("com.android.internal.view.menu.IconMenuItemView")) {
try {
LayoutInflater f = getLayoutInflater();
final View view = f.createView(name, null, attrs);
new Handler().post(new Runnable() {
public void run() {
// set the background drawable
view.setBackgroundColor(Color.GRAY);
// set the text color
((TextView) view).setTextColor(Color.DKGRAY);
}
});
return view;
} catch (InflateException e) {
} catch (ClassNotFoundException e) {
} finally {
Log.i(Constants.DETAILS_WORKSHEET_ACTIVITY,
"menu colour changed");
}
}
return null;
}
});
return super.onCreatePanelMenu(featureId, menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.birthday:
detailsAdapter = new ListViewCustomeAdapter(this,
DatabaseOperation.friendsBirthdayDetailsArrayListObject
.size(),
DatabaseOperation.friendsBirthdayDetailsArrayListObject,
true);
listViewFriendsDetails.setAdapter(detailsAdapter);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
// Intent detailsIntent = new Intent(BuddiesActivity.this,
// DetailsActivity.class);
// detailsIntent
// .setAction(DatabaseOperation.friendsDetailsArrayListObject
// .get(position).getEmailId());
// startActivity(detailsIntent);
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listview);
/*
* Listing the songs and its details
*/
listViewFriendsDetails = (ListView) findViewById(R.id.listView);
detailsAdapter = new ListViewCustomeAdapter(this,
DatabaseOperation.friendsDetailsArrayListObject.size(),
DatabaseOperation.friendsDetailsArrayListObject, false);
listViewFriendsDetails.setAdapter(detailsAdapter);
registerForContextMenu(listViewFriendsDetails);
listViewFriendsDetails
.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
System.out
.println("buttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt");
}
});
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.add(0, 0, 0, "call");
menu.add(0, 0, 0, "Message");
menu.add(0, 0, 0, "Find him/her");
menu.add(0, 0, 0, "Find his/her home");
}
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterView.AdapterContextMenuInfo info;
try {
info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
} catch (ClassCastException e) {
Log.e("", "bad menuInfo", e);
return false;
}
Toast.makeText(
this,
"id = "
+ DatabaseOperation.friendsDetailsArrayListObject.get(

Toast.LENGTH_SHORT).show();
return true;
}
}
