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;

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 have a ListView and a Toolbar above of it in my Activity. I want to replace the Toolbar default icons (search and settings) with delete and edit icons when clicking an item of the ListView to perform some action.
So what I've understood from your question, you're looking for ActionMode which might serve your purpose.
So here's an implementation guideline.
Declare an ActionMode in your Activity and let your Activity to implement ActionMode.Callback.
public class YourActivity extends AppCompatActivity implements ActionMode.Callback {
// Declare ActionMode here
private ActionMode actionMode;
// Now implement the callback functions for ActionMode
#Override
public boolean onPrepareActionMode(ActionMode actionMode, Menu menu) {
return false;
}
#Override
public boolean onCreateActionMode(final ActionMode actionMode, Menu menu) {
MenuInflater inflater = actionMode.getMenuInflater();
// Inflate your menu here
inflater.inflate(R.menu.list_item_click_menu, menu);
return true;
}
#Override
public boolean onActionItemClicked(ActionMode actionMode, MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.action_delete:
// Do something
actionMode.finish();
return true;
case R.id.action_edit:
// Do something
actionMode.finish();
return true;
default:
return false;
}
}
#Override
public void onDestroyActionMode(ActionMode actionMode) {
try {
this.actionMode = null;
// Do something. Reset the views maybe?
} catch (Exception e) {
e.printStackTrace();
}
}
}
Now to initiate your ActionMode you need to have this in your onClick function of the list item.
listItem.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (actionMode != null) {
return true;
}
// Show ActionMode
actionMode = startSupportActionMode(this);
actionMode.invalidate();
}
});
You may need to reset the ActionMode sometimes.
#Override
public void onResume() {
super.onResume();
if (actionMode != null) {
actionMode.finish();
actionMode = null;
}
}
I Have a tablayout, within which in each tab, i have listviews that use custom adapters. I have setup the listview to Multi MODAL and defined a cabmenu. I have used the same cabmenu in another activity having similar tabs and listviews. I dont understand what i am missing , the cab menu is not appearing on long press on the listview items. The only difference between the other activity and this one is, the other has an action bar. Below is the code where the cab menu isnt working.
public void showLists(){
adapter=new CustomItemAdapter(getActivity(),listtype,fruititem,listid);
lv=(ListView) getView().findViewById(R.id.fruits);
lv.setAdapter(adapter);
lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
lv.setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener() {
#Override
public void onItemCheckedStateChanged(ActionMode mode, int position, long id, boolean checked) {
if (checked) {
selection.add(fruititem.get(position));
count++;
} else {
selection.remove(fruititem.get(position));
count--;
}
TextView tv = (TextView) getActivity().getLayoutInflater().inflate(R.layout.contextual_title, null);
tv.setText(count + " selected");
mode.setCustomView(tv);
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
MenuInflater menuinflater = new MenuInflater(getContext());
menuinflater.inflate(R.menu.cabmenu, menu);
return true;
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
if (item.getItemId() == R.id.deleteic) {
for (ItemLists s : selection) {
dbHandler.deleteItem(s);
}
adapter.notifyDataSetChanged();
mode.finish();
showLists();
}
mode.finish();
return true;
}#Override
public void onDestroyActionMode(ActionMode mode) {
count = 0;
selection.clear();
}
});
}
My app has a ListView and I'm using a Contextual Action Bar for devices above SDK 11 and the old popup contextual actions for older devices. I know there's a way to use a CAB with older devices but I tried to implement it and found it wasn't worth the effort for devices that will eventually be obsolete. I know it's some code duplication, but, in theory, I will be getting rid of the old popup actions (emphasis on "in theory").
Anyhow, when I use the emulator, the CAB works fine, but the old popup actions for older devices seems to hit onContextItemSelected twice when I put a breakpoint in that event. I've just start implement a ViewPager for my app and this wasn't happening before the ViewPager so not sure if that is causing the issue.
This is the code I'm using:
public class MyFragment extends SherlockListFragment
{
private ListView mListView;
private android.view.ActionMode mActionMode;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateContextMenu(final ContextMenu menu, final View v, final ContextMenuInfo menuInfo)
{
super.onCreateContextMenu(menu, v, menuInfo);
if (this.mActionMode != null) return;
menu.add(1, 0, 0, "Delete");
menu.add(1, 1, 0, "Save");
}
#Override
public void onActivityCreated(final Bundle icicle)
{
mListView = getListView();
if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB)
{
mListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
mListView.setMultiChoiceModeListener(new MultiChoiceModeListener() {
#Override
public boolean onCreateActionMode(android.view.ActionMode mode, android.view.Menu menu) {
// Inflate the menu for the CAB
menu.clear();
menu.add(1, 1, 2, "Delete").setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
menu.add(1, 3, 1, "Save").setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
return true;
}
#Override
public boolean onActionItemClicked(android.view.ActionMode mode, android.view.MenuItem item) {
mActionMode = mode;
if (item.getGroupId() == 1)
{
switch(itemId)
{
case 0:
DeleteItem();
break;
case 1:
SaveItem();
break;
}
}
}
}
}
}
#Override
public boolean onContextItemSelected(final android.view.MenuItem item) {
if (item.getGroupId() == 1) {
final AdapterContextMenuInfo info = (AdapterContextMenuInfo)item.getMenuInfo();
final Integer position = info.position;
final int itemId = item.getItemId();
switch(itemId)
{
case 0:
DeleteItem();
break;
case 1:
SaveItem();
break;
}
}
return super.onContextItemSelected(item);
}
#Override
public void onPrepareOptionsMenu(Menu menu) {
super.onPrepareOptionsMenu (menu);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.my_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
}

This solution on this question fixed my issue:
How to handle onContextItemSelected in a multi fragment activity?
using getUserVisibleHint() in onContextItemSelected.
Method must return true to consume the selection.
Docs here
#Override

final AdapterContextMenuInfo info = (AdapterContextMenuInfo)item.getMenuInfo();
final Integer position = info.position;
final int itemId = item.getItemId();
switch(itemId)
{
case 0:

return true;
case 1:

}
}
return super.onContextItemSelected(item);
}
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.
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).
