delete a dynamically created button android

Ok, what I'm trying to do is, something like a tag search function.
What I did was create Button ArrayList, and whenever a user tries to input ",", it automatically creates a button and inserts it into the ArrayList, which ultimately registers to the LinearLayout.
It creates well, but does not delete well.
I get the error that the index is out of bounds, but was in no luck of finding out which statement should I use. Could you help me?
Thx in advance.

etSearch.setText("");
etSearch.setSelection(0);
}
}
}
#Override
public void afterTextChanged(Editable s) {
}
};
etSearch.addTextChangedListener(tagWatcher);
}
}

I solved it using indexOfChild function. It kept on throwing me indexOutOfBounds error. Thx

Because of the reputations, I can not add comment. SO I post here.
In the button click listener:
bTagButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
tagCollection.remove(tagCollection.indexOf(this));
llTagCollection.removeAllViews();
int i = 0;
while (i < (tagCollection.size())) {
if (tagCollection.get(i) != null) {
llTagCollection.addView(tagCollection.get(i));
}
i += 1;
}
}
});
You remove the button by tagCollection.remove(tagCollection.indexOf(this));. Here this means the OnClickListener instance, not the button clicked. SO you should remove buttons by：
tagCollection.remove(tagCollection.indexOf(v));

How to Keep Highlighted ListView Item and Its Status in the Contextual Action Bar during Device Orientation Change

I have a listview implemented with its choice mode set to CHOICE_MODE_MULTIPLE_MODAL. Here is some of the code:
listView.setMultiChoiceModeListener(new MultiChoiceModeListener() {

This works great, long clicking a listview item highlights it and it works fine. However, once I change the device orientation from portrait to landscape and vice versa, the highlighting is gone and the Contextual Action Bar is still showing however it doesn't show anything is selected. Any help? I've tried making selectors and drawables and manually doing it that way and still no luck. I've spent weeks on this one issue and I'm wondering if somebody out there knows how to solve it.
Thanks.

See if you can using this helps:

Issue with setting and opening fragments in Android App

I am having a issue, as my app is crashing instead of opening the fragments. I have a ListActivity, that takes you to another activity; and in that other activity, there are two fragments. The ListActivity is expecting a result from one of the fragments.
My code was working prior to adding the fragments! However the fragments are no longer showing up and the app closes...does anyone possibly know what my issue could be? And any advice on how to take this issue? I sincerely appreciate all and any help, thank you! My code is below.
The ListActivity.java:
public class LyricList extends ListActivity {
private static final int ACTIVITY_CREATE=0;
private static final int ACTIVITY_EDIT=1;
private static final int INSERT_ID = Menu.FIRST;
private static final int DELETE_ID = Menu.FIRST + 1;
private LyricsDbAdapter mDbHelper;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_lyriclist);
mDbHelper = new LyricsDbAdapter(this);
mDbHelper.open();
fillData();
registerForContextMenu(getListView());
}
private void fillData() {
Cursor lyricsCursor = mDbHelper.fetchAllLyrics();
startManagingCursor(lyricsCursor);
String[] from = new String[]{LyricsDbAdapter.KEY_TITLE};
int[] to = new int[]{R.id.text1};
SimpleCursorAdapter lyrics =
new SimpleCursorAdapter(this, R.layout.lyrics_row, lyricsCursor, from, to);
setListAdapter(lyrics);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0, INSERT_ID, 0, R.string.menu_insert);
return true;
}
#Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
switch(item.getItemId()) {
case INSERT_ID:
createLyric();
return true;
}
return super.onMenuItemSelected(featureId, item);
}
#Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.add(0, DELETE_ID, 0, R.string.menu_delete);
}
#Override
public boolean onContextItemSelected(MenuItem item) {
switch(item.getItemId()) {
case DELETE_ID:
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
mDbHelper.deleteLyric(info.id);
fillData();
return true;
}
return super.onContextItemSelected(item);
}
private void createLyric() {
Intent i = new Intent(this, NextActivity.class);
startActivityForResult(i, ACTIVITY_CREATE);
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
Intent i = new Intent(this, NextActivity.class);
i.putExtra(LyricsDbAdapter.KEY_ROWID, id);
startActivityForResult(i, ACTIVITY_EDIT);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
fillData();
}
}
The other activity class that should be opening via the listActivity:
public class NextActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_next);
ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
Tab one = actionBar.newTab().setText("Lyric Editor");
Tab two = actionBar.newTab().setText("Loops");
one.setTabListener(new MyTabListener(new LyricEditorFragment()));
two.setTabListener(new MyTabListener(new LoopsFragment()));
actionBar.addTab(one);
actionBar.addTab(two);
}
public class MyTabListener implements TabListener{
Fragment fragment;
public MyTabListener(Fragment f){
fragment = f;
}
#Override
public void onTabReselected(Tab arg0, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
#Override
public void onTabSelected(Tab arg0, FragmentTransaction ft) {
// TODO Auto-generated method stub
ft.replace(R.id.frame1, fragment);
}
#Override
public void onTabUnselected(Tab arg0, FragmentTransaction ft) {
// TODO Auto-generated method stub
ft.remove(fragment);
}
}
}
Not sure if you want to see the fragment class, but here is this just incase:
public class LyricEditorFragment extends Fragment {
private EditText mTitleText;
private EditText mBodyText;
private Long mRowId;
private LyricsDbAdapter mDbHelper;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mDbHelper = new LyricsDbAdapter(getActivity());
mDbHelper.open();
mTitleText = (EditText) getView().findViewById(R.id.title);
mBodyText = (EditText) getView().findViewById(R.id.body);
Button confirmButton = (Button) getView().findViewById(R.id.confirm);
mRowId = (savedInstanceState == null) ? null :
(Long) savedInstanceState.getSerializable(LyricsDbAdapter.KEY_ROWID);
if (mRowId == null) {
Bundle extras = getActivity().getIntent().getExtras();
mRowId = extras != null ? extras.getLong(LyricsDbAdapter.KEY_ROWID)
: null;
}
populateFields();
confirmButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
getActivity().setResult(Activity.RESULT_OK);
getActivity().finish();
}
});
}
private void populateFields() {
if (mRowId != null) {
Cursor lyric = mDbHelper.fetchLyric(mRowId);
getActivity().startManagingCursor(lyric);
mTitleText.setText(lyric.getString(
lyric.getColumnIndexOrThrow(LyricsDbAdapter.KEY_TITLE)));
mBodyText.setText(lyric.getString(
lyric.getColumnIndexOrThrow(LyricsDbAdapter.KEY_BODY)));
}
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
saveState();
outState.putSerializable(LyricsDbAdapter.KEY_ROWID, mRowId);
}
#Override
public void onPause() {
super.onPause();
saveState();
}
#Override
public void onResume() {
super.onResume();
populateFields();
}
private void saveState() {
String title = mTitleText.getText().toString();
String body = mBodyText.getText().toString();
if (mRowId == null) {
long id = mDbHelper.createLyric(title, body);
if (id > 0) {
mRowId = id;
}
} else {
mDbHelper.updateLyric(mRowId, title, body);
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
//return super.onCreateView(inflater, container, savedInstanceState);
View view = inflater.inflate(R.layout.activity_lyriceditor, container, false);
return view;
}
}

The problem is that you are getting a View from the activity which will return null.. you need to create/inflate the view from the onCreateView..
click here and follow the steps on how to create and use a view from fragment..

AlertDialog SingleChoiceItems not working

I'm trying to make a SingleChoiceItems AlertDialog with an OK and Cancel button which gives the user the option on a onItemLongClick from a ListView to 1.view the user's profile 2.send the user a message and 3.delete the user from the friends list.
I haven't done option 1 and 2 yet but I'm trying to make option 3 right now in which I included the Database delete method and a toast that says "friend removed" but when I select Option 3 and hit ok that row does not get deleted or I see the Toast saying the user was deleted.Here is my code for the Activity I'm using the Dialog.
public class PlayAFriend extends ListActivity {
DBAdapter DBAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.list_items);
final DBAdapter db = new DBAdapter(this);
DBAdapter = db.open();
ListView FriendLV = (ListView) findViewById(android.R.id.list);
final Cursor friendslist = db.GetAllFriends();
String[] from = new String[] { "FRIENDS" }; // your column/columns here
int[] to = new int[] { R.id.textview_friends };
#SuppressWarnings("deprecation")
ListAdapter cursorAdapter = new SimpleCursorAdapter(this,
R.layout.list_items, friendslist, from, to, 0);
FriendLV.setAdapter(cursorAdapter);

You have to save the choice when select a radio button, the other int parameter in the button does not represent the choice.
Make int mChoice; a class member
public class PlayAFriend extends ListActivity {
DBAdapter DBAdapter;
int mChoice;
......
......
#Override
public Dialog onCreateDialog(final int id) {
final DBAdapter db = new DBAdapter(this);
db.open();

case 0:
return new AlertDialog.Builder(this)
.setIcon(R.drawable.icon)
.setTitle("Select an Option")
.setSingleChoiceItems(items, id,
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog,
int choice) {
mChoice = choice; // save the choice
}
}
)
.setPositiveButton("Ok",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog,
int choice) {
// TODO Auto-generated method stub
if (mChoice == 0) {
Toast.makeText(getBaseContext(),
"Test", Toast.LENGTH_SHORT)
.show();
} else if (mChoice == 1) {
Toast.makeText(getBaseContext(),
"Test2", Toast.LENGTH_SHORT)
.show();
} else if (mChoice == 2) {
Toast.makeText(getBaseContext(),
"Friend Removed",
Toast.LENGTH_SHORT).show();
final TextView friends = (TextView) findViewById(R.id.textview_friends);
String deletedfriend = friends
.getText().toString();
db.DeleteFriends(deletedfriend);
}
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog,

This needs to be outside of your onCreate():
#Override // the error is with this method decleration
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(ls, v, position, id);
}

You're creating the onListItemClick method inside the onCreate method. Move it outside the onCreate method :)
