I am currently working on android project and making use of fragments and ListViews/ListFragments. I have contextual action bars working on standard activities such as a ListActivity.
Now I am trying to do the same sort of thing but on a fragment layout. I have a MainActivity which extends Activity which inflates the XML for the layout that contains the 2 fragments, fragment A and fragment B.
Fragment A extends ListFragment and contains a ListView which is populated from data within an SQLite Database. When I have got a contextual action bar working on a standard ListActivity I have a class that Extends ListView.MultiChoiceModeListener but this isn't available for a ListFragment class or a standard activity so how would I go about implementing this.
The basic thing I want to achieve is when someone long presses the item within a ListView within FragmentA which extends ListFragment, the action bar contextually changes and the user can then select multiple items from within the ListView.
Thanks for any help you can provide.
When I have got a contextual action bar working on a standard
ListActivity I have a class that Extends
ListView.MultiChoiceModeListener but this isn't available for a
ListFragment class or a standard activity so how would I go about
implementing this.
I don't see how MultiChoiceModeListener isn't available (maybe I didn't understand what you try to do). From your comment I assumed you use the fragments from the compatibility package.
Below is an example with a FragmentActivity with two static fragments and each of those fragments triggers the contextual action bar with their own menus options.
The FragmentActivity is very simple, it just holds the two fragments below:
// the list fragment
public class ListCABFragment extends ListFragment {
private String[] mCountries = { "Romania", "Germany", "England", "USA",
"Japan", "France" };
private static final boolean POST_HONEYCOMB = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB;
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if (POST_HONEYCOMB) {
// make sure we are on a version above Honeycomb otherwise will
// access things that aren't available
postHoneycombCAB();
} else {
// probably do nothing and implement the normal context menu?!?
}
setListAdapter(new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, mCountries));
}
#SuppressLint({ "NewApi", "NewApi" })
private void postHoneycombCAB() {
getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
getListView().setOnItemLongClickListener(new OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
int position, long id) {
((ListView) parent).setItemChecked(position,
((ListView) parent).isItemChecked(position));
return false;
}
});
getListView().setMultiChoiceModeListener(new MultiChoiceModeListener() {
private int nr = 0;
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
getActivity().getMenuInflater().inflate(R.menu.listcab_menu,
menu);
return true;
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.item1:
Toast.makeText(getActivity(), "Option1 clicked",
Toast.LENGTH_SHORT).show();
break;
case R.id.item2:
Toast.makeText(getActivity(), "Option2 clicked",
Toast.LENGTH_SHORT).show();
break;
}
return false;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
nr = 0;
}
#Override
public void onItemCheckedStateChanged(ActionMode mode,
int position, long id, boolean checked) {
if (checked) {
nr++;
} else {
nr--;
}
mode.setTitle(nr + " rows selected!");
}
});
}
}
and the other fragment for a Fragment which has a layout composed from a RadioGroup which triggers the CAB when a RadioButton is selected:
public class SimpleCABFragment extends Fragment implements Callback {
private static final boolean POST_HONEYCOMB = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.frag_simplecabfragment, container,
false);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
RadioGroup rg = (RadioGroup) getView().findViewById(R.id.radioGroup1);
rg.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (POST_HONEYCOMB) {
// this could be improved so we don't need to create the
// option
// menu if it is already available
getActivity().startActionMode(SimpleCABFragment.this);
} else {
// something else
}
}
});
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
if (item.getItemId() == R.id.itemradio) {
Toast.makeText(getActivity(), "CAB for Radiogroup!",
Toast.LENGTH_SHORT).show();
}
return false;
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
getActivity().getMenuInflater().inflate(R.menu.simplecab_menu, menu);
return true;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}
}
See if this is what you're looking for (you can find a full sample including the layouts and menus files in my github project).

I have a ListView with a number of items on it. When I long click on one of the items, it brings up a CAB and I can select a number of these items and perform group operations on them. This is dandy. I currently set a MultiChoiceModeListener on my ListView to achieve this (and have put the relevent code to that effect below).
Is it possible for this CAB to be brought up from a short click, rather than a long click?
public class ViewInventoryActivity extends ActionBarActivity
{
private ArrayList<InventoryEntry> list;
private ListView listView;
private ListViewAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_inventory);
list = getList();
listView = (ListView) findViewById(R.id.listview_inventory);
adapter = new ListViewAdapter(this, R.layout.listview_inventory_row, list);
// This is a custom written adapter
listView.setAdapter(adapter);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
listView.setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener()
{
#Override
public void onItemCheckedStateChanged(ActionMode mode, int position, long id, boolean checked)
{
mode.setTitle(listView.getCheckedItemCount() + " selected");
adapter.toggleSelection(position);
// toggleSelection keeps track of what is currently selected
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu)
{
mode.getMenuInflater().inflate(R.menu.menu_view_inventory, menu);
return true;
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item)
{
return false;
// This does have some logic, but it's not important here
}
#Override
public void onDestroyActionMode(ActionMode mode)
{
adapter.removeSelection();
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu)
{
return false;
}
});
}
}
I have been following this tutorial: http://developer.android.com/guide/topics/ui/menus.html#CAB. However, when I run the application, I get an error:

EDIT 1: this line
public class MainActivity extends ActionBarActivity implements AbsListView.MultiChoiceModeListener{
showed me an error in Android Studio, and when I clicked Alt + Enter, it showed me two options: Make the class abstract, or implement its methods.
The first option gave me the initial problem, so now I went for option 2. Here are the additional methods implemented :
#Override
public void onItemCheckedStateChanged(ActionMode mode, int position, long id, boolean checked) {
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
return false;
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
return false;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
}
Now, my doubt is: these are exactly the same methods in between LABEL 1 and LABEL 2, and erasing any one set will lead to errors. What should I do?
You are getting this error: Unable to instantiate activity because you made your activity abstract. Remove that and implement the methods of AbsListView.MultiChoiceModeListenerinterface.
When you're implementing an Interface so you have to implement all the methods you have listed. If you don't know what to do with method you don't use just leave them as they are.
Now, my doubt is: these are exactly the same methods in between LABEL 1 and LABEL 2, and erasing any one set will lead to errors. What should I do?
You shouldn't have two of the same. Try using #Override annotation on the methods you implemented.
I've googled a lot, and find some tutorials and answers here in stackoverflow, but I am facing some difficults to resolve this issue.
I have a Fragment with a WebView, and I want to show my custom Contextual Action Bar when the user selects some text of my web view. I have two main issues here:
1 Currently, my custom CAB is showed when the user performs long click in any part of the web view.
2 The text is not selected when the user performs long click in some text of my web view.
Some of my current code:
Custom interface:
public class SelectActionModeCallback implements ActionMode.Callback {
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
return false;
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
return false;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
}
}
Custom WebView
public class CustomWebView extends WebView {
private SelectActionModeCallback actionModeCallback;
public CustomWebView(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
public ActionMode startActionMode(Callback callback) {
actionModeCallback = new SelectActionModeCallback();
return super.startActionMode(actionModeCallback);
}
In my fragment, I have this:
#Override
public void onResume() {
super.onResume();
myWebView.setOnLongClickListener(new View.OnLongClickListener() {
public boolean onLongClick(View view) {
if (mActionMode != null) {
Toast.makeText(getActivity(), "test", Toast.LENGTH_SHORT).show();
return false;
}
mActionMode = getActivity().startActionMode(mActionModeCallback);
view.setSelected(true);
return true;
}
});
}
private SelectActionModeCallback mActionModeCallback = new SelectActionModeCallback() {
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
MenuInflater inflater = mode.getMenuInflater();
inflater.inflate(R.menu.custom, menu);
return true;
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.action_sustom:
customMethod();
mode.finish();
return true;
default:
return false;
}
}
#Override
public void onDestroyActionMode(ActionMode mode) {
mActionMode = null;
}
};
THERE IS A BETTER WAY! See the following answer: https://stackoverflow.com/a/22391169/2608235
In short, you can't use an OnLongClickListener and keep the selection within a WebView. Android does some weird stuff behind the scenes for selecting text within WebViews. If you override OnLongClickListener in order to call startActionMode, you will lose the selection, as you have found out.
What you should do instead is override startActionMode in your fragment, rather than its parent View (in your case, CustomWebView).
I don't have the mod permission to mark this question as a duplicate, but it is.
See my question for more info: Use a custom contextual action bar for WebView text selection
i implemented a contextual action mode bar in a nested fragement. This fragment is part of a view pager and the view pager is also a fragment and part of a navigation drawer.
My Problem: I want to close the contextual action mode bar if the fragment is no more focused. So, if I swipe through the view pager the action mode bar should close. But if I use the onPause() method of the nested fragment, the method is not called directly. Often it waits until i swiped two or three times forward... Here are some pictures:
In the second picture you can see that the action mode bar is still there. So my question is:
In which method should I call my actionModeBar.finish() method, to close directly the action mode bar if i leave the fragment?
Maybe the code of the fragment helps you:
public class EditorFragment extends Fragment {
private static final String KEY_POSITION="position";
ListView listView;
private boolean isMultipleList = false;
private ActionMode acMode;
private int counterChecked = 0;
private ActionMode.Callback modeCallBack = new ActionMode.Callback() {
public boolean onPrepareActionMode(ActionMode mode, Menu menu){
return false;
}
public void onDestroyActionMode(ActionMode mode) {
listView.clearChoices();
for (int i = 0; i < listView.getChildCount(); i++)
listView.setItemChecked(i, false);
listView.post(new Runnable() {
#Override
public void run() {
listView.setChoiceMode(ListView.CHOICE_MODE_NONE);
}
});
isMultipleList = false;
counterChecked = 0;
mode = null;
}
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
mode.setTitle("1 Aufgabe");
mode.getMenuInflater().inflate(R.menu.actionmode, menu);
return true;
}
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.actionmode_delete:
int choiceCount = listView.getCount();
SparseBooleanArray spBoolArray = listView.getCheckedItemPositions();
DBAufgaben db = new DBAufgaben(MainActivity.getMContext());
db.open();
for (int i = 0; i < choiceCount; i++) {
if(spBoolArray.get(i)){
db.deletContact(listView.getItemIdAtPosition(i));
}
}
Cursor cursor = db.getAllRecords();
AdapterEingang adapterE = new AdapterEingang(MainActivity.getMContext(), cursor, 0);
listView.setAdapter(adapterE);
db.close();
mode.finish();
break;
case R.id.actionmode_cancel:
mode.finish();
break;
}
return false;
}
};
//......//
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = null;
int position = getArguments().getInt(KEY_POSITION, -1);
switch(position){
case 0:
rootView = inflater.inflate(R.layout.pager_list, null);
listView = (ListView) rootView.findViewById(R.id.pager_list);
Context context = MainActivity.getMContext();
DBAufgaben db = new DBAufgaben(context);
db.open();
Cursor cursor = db.getAllRecords();
AdapterEingang adapterE = new AdapterEingang(context, cursor, 0);
listView.setAdapter(adapterE);
db.close();
listView.setOnItemLongClickListener(new OnItemLongClickListener(){
#Override
public boolean onItemLongClick(AdapterView<?> adapterView, View view,
int position, long id) {
if(!isMultipleList){
acMode = MainActivity.getInstance().startActionMode(modeCallBack);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setItemChecked(position, true);
isMultipleList = true;
counterChecked++;
setNewTitle();
} else {
listView.setItemChecked(position, true);
counterChecked++;
setNewTitle();
}
return true;
}
});
listView.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position,
long id) {
Log.d(getTag(), "Datensatz: "+String.valueOf(id));
if(isMultipleList){
if(listView.isItemChecked(position)){
listView.setItemChecked(position, true);
counterChecked++;
setNewTitle();
} else {
listView.setItemChecked(position, false);
counterChecked--;
setNewTitle();
}
}
}
});
break;
default:
rootView = inflater.inflate(R.layout.frag_dummy, null);
TextView txt = (TextView) rootView.findViewById(R.id.dummy_txt);
txt.setText(String.valueOf(position));
break;
}
return(rootView);
}
public void setNewTitle(){
if(counterChecked == 1){
acMode.setTitle(counterChecked+" Aufgabe");
} else {
acMode.setTitle(counterChecked+" Aufgaben");
}
}
#Override
public void onPause(){
super.onPause();
if(isMultipleList){
acMode.finish();
}
}
}
ViewPagers keep multiple pages active at any one time (by default, the page before and page after the currently shown page), hence why onPause() is not called until you swipe two pages away.
Your best bet would be to use a ViewPager.OnPageChangeListener, and show and hide the ActionMode in onPageSelected(..) (i.e. if the page selected isn't the one with the ActionMode, hide the ActionMode). You'll likely have to implement this in the Activity which hosts your ViewPager.
Here's what worked for me --
Hold a static reference to the action mode in MyFragment:
public static ActionMode mActionMode;
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
mActionMode = mode;
return true;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
mActionMode = null;
}
Set ViewPager.OnPageChangeListener in MyViewPagerActivity.
mViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
....
#Override
public void onPageScrollStateChanged(int state) {
if(MyFragment.mActionMode != null) MyFragment.mActionMode.finish();
}
});
This worked for me:
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
if (!isVisibleToUser && this.listView != null) {
//HACK this is done in order to finish the contextual action bar
int choiceMode = this.listView.getChoiceMode();
this.listView.setChoiceMode(choiceMode);
}
}
I combined code from the OP with the override suggested by user pomber:
I save the ActionMode to a class field when the action mode is created.
I set the field back to null when the action mode is destroyed.
I override setUserVisibleHint in my fragment and call ActionMode#finish() if the fragment isn't visible in the view pager.
I also call ActionMode#finish() in the onPause() method of the fragment to close the fragment if the user navigates elsewhere.
Code:
#Nullable
ActionMode mActionMode = null;
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// Start out with a progress indicator.
setListShownNoAnimation(false);
setEmptyText(getText(R.string.no_forms_in_progress));
getListView().setChoiceMode(AbsListView.CHOICE_MODE_MULTIPLE_MODAL);
getListView().setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener() {
#Override
public void onItemCheckedStateChanged(ActionMode mode, int position, long id, boolean checked) {
// Here you can do something when items are selected/de-selected,
// such as update the title in the CAB
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
MenuInflater inflater = mode.getMenuInflater();
inflater.inflate(R.menu.context_saved_item, menu);
inflater.inflate(R.menu.context_instance_list, menu);
mActionMode = mode;
return true;
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.action_delete:
confirmDelete(getListView().getCheckedItemIds());
return true;
case R.id.action_print:
print(getListView().getCheckedItemIds());
return true;
}
return false;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
mActionMode = null;
}
});
}
#Override
public void onPause() {
super.onPause();
if (mActionMode != null) {
mActionMode.finish();
}
}
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (mActionMode != null && !isVisibleToUser) {
mActionMode.finish();
}
}
You can use the onDestroyOptionsMenu() method inside your Fragment:
public void onDestroyOptionsMenu() {
super.onDestroyOptionsMenu();
if (mActionMode != null) {
mActionMode.finish();
mActionMode = null;
}
}
I've set up an ActionMode callback for use as the contextual ActionBar (CAB) within an ActionBarSherlock using project.
I'm trying to set up multiple select so that I can delete multiple items in a ListView.
I noticed while debugging, when the contextual ActionBar (CAB) is not open and I call isItemChecked() on a list item that I touch, it returns false as it should. But when the CAB IS open, items that I touch (that I haven't touched before) return true on calls to isItemChecked(). Then when I call delete on the array from getCheckedItemIds(), that array does not contain the items that were previously returning true for isItemChecked().
Has anyone seen this?
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.habit);
habitListView = (ListView)findViewById(R.id.habitsListView);
habitListView.setAdapter(mAdapter);
habitListView.setChoiceMode(AbsListView.CHOICE_MODE_MULTIPLE);
habitListView.setItemsCanFocus(false);
habitListView.setOnItemLongClickListener(new MyOnItemLongClickListener());
habitListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (habitListView.isItemChecked(position)) { // for debugging, returns false here
// when CAB isnt up.
int h = 2;
}
// handle differently when CAB is on.
if (mMode != null) {
if (habitListView.isItemChecked(position)) { // returns true here when CAB is up
// but this is the first time I'm
// clicking the item
habitListView.setItemChecked(position, false);
// turn CAB off if this is the last to be unchecked
if (habitListView.getCheckedItemIds().length == 0) {
mMode.finish();
}
} else {
habitListView.setItemChecked(position, true);
}
} else {
// start detail/edit view activity
}
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getSupportMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.menu_create:
Habit test = new Habit("FLOSS", "GOOD", "", "");
mDbHelper.createHabitEntry(test);
mAdapter.changeCursor(mDbHelper.getAllEntries());
break;
}
return false;
}
private class MyOnItemLongClickListener implements OnItemLongClickListener {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
habitListView.setItemChecked(position, true);
mMode = startActionMode(new MyActionModeCallback());
return true;
}
}
private class MyActionModeCallback implements ActionMode.Callback {
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
// TODO Auto-generated method stub
return false;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
habitListView.setOnItemLongClickListener(new MyOnItemLongClickListener());
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
mode.getMenuInflater().inflate(R.menu.main_long_click_context, menu);
habitListView.setOnItemLongClickListener(null);
return true;
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_delete:
long[] selected = habitListView.getCheckedItemIds();
if (selected.length > 0) {
for (long id : selected) {
mDbHelper.deleteEntry(id);
}
}
mAdapter.changeCursor(mDbHelper.getAllEntries());
mode.finish();
break;
}
return true;
}
};
So what has worked for me is to just use
habitListView.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
//handle differently when CAB is on.
if (mMode != null){
view.setSelected(!view.isSelected());
updateCABtitle();
//turn CAB off if this is the last to be unchecked
if (habitListView.getCheckedItemIds().length == 0){
mMode.finish();
}
} else {
//start detail/edit view activity
Intent intent = new Intent(getApplicationContext(), HabitDetailActivity.class);
startActivity(intent);
}
}
});
and
private class MyOnItemLongClickListener implements OnItemLongClickListener{
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
int position, long id) {
habitListView.setItemChecked(position, true);
mMode = startActionMode(new MyActionModeCallback());
updateCABtitle();
return true;
}
}
I don't really understand why setItemChecked() is not working for onItemClick() but seems to be for onItemLongClick(). It looks as though there is a default click handler that gets called in AbsListView.PerformItemClick() that must do some toggling of checked/unchecked or something.
