I have created cardview as single item of RecyclerView
and in my cardview, I have created a popup menu programmatically..
I want to change the title of menu item at run-time
is it possible to update menu item title in onMenuItemClick() method?
My HomeFragment.java looks like-
private void showPopupMenu(View view, int position,String post_key) {
// inflate menu
PopupMenu popup = new PopupMenu(view.getContext(),view );
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.card_view_menu, popup.getMenu());
popup.setOnMenuItemClickListener(new MyMenuItemClickListener(position,post_key));
popup.show();
}
class MyMenuItemClickListener implements PopupMenu.OnMenuItemClickListener {
private int position;
DatabaseReference mPostDatabase;
private String post_key;
Menu menu;
MyMenuItemClickListener(int positon,String post_key) {
this.position = positon;
this.post_key=post_key;
mPostDatabase=FirebaseDatabase.getInstance().getReference().child("Posts");
}
#Override
public boolean onMenuItemClick(final MenuItem item) {
int id=item.getItemId();
switch (id){
case R.id.delete_post:
mPostDatabase.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
if(dataSnapshot.hasChild(post_key)){
String from_id= String.valueOf(dataSnapshot.child(post_key).child("from").getValue());
if(from_id.equals(FirebaseAuth.getInstance().getCurrentUser().getUid())){
mPostDatabase.child(post_key).removeValue();
}
else {
//here i want to change the title
item.setTitle("Save Post");//it doesn't work
}
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
return false;
}
}
after this line :
//here i want to change the title
item.setTitle("Save Post");
call below function
invalidateOptionsMenu();

Is it possible to focus the List View Items through any button click?
Like i want that when user click on Floating Action Button then the listview gets focused. I dont want to show checkbox type layout on button clicked. I just want to show the same like in the screenshot on Button click.
What i did is I put the listview onItemLongClick code in the button click blocks but it doesnot work.
fabButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
listViewMessages.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
listViewMessages.setMultiChoiceModeListener(new MultiChoiceModeListener() {
#Override
public void onItemCheckedStateChanged(ActionMode mode, int position,
long id, boolean checked) {
tv.setText(listViewMessages.getCheckedItemCount()+ " Selected");
}
#Override
public boolean onActionItemClicked(final ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.menu:
}
});
mode.finish();
return true;
default:
return false;
}
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
// Inflate the menu for the CAB
MenuInflater inflater = mode.getMenuInflater();
inflater.inflate(R.menu.contextual, menu);
fabButton.setVisibility(View.INVISIBLE);
fabButtonn.setVisibility(View.VISIBLE);
fabButtonn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
for ( int i=0; i< messageListAdapter.getCount(); i++ ) {
listViewMessages.setItemChecked(i, true);
}
}
});
return true;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
fabButton.setVisibility(View.VISIBLE);
fabButtonn.setVisibility(View.GONE);
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
// Here you can perform updates to the CAB due to
// an invalidate() request
return false;
}
});
With this code if user clcik on button then he/she has too long press items again to focus the list items which is not what i want. I want to focus items right when button click. Any explanation or link provided will be helpful
Im trying to display the item name of the listview when its popupmenu is being clicked but i'm have trouble with it because it always show or returns "false" value. Any ideas how to solve this? thanks
public void toast(View v){
showPopupMenu(v);
}
private void showPopupMenu(View v){
PopupMenu pop = new PopupMenu(CompanyActivity.this, v);
pop.getMenuInflater().inflate(R.menu.menu,pop.getMenu());
pop.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
if(item.getItemId() == R.id.view){
Toast.makeText(getApplicationContext(),item.getItemId(),Toast.LENGTH_SHORT)
.show();
return true;
}
return false;
}
});
pop.show();
}
Edited: I want to get the value of the list item in the listview being clicked but it shows the menu item that is being clicked.
public void toast(View v){
showPopupMenu(v);
}
private void showPopupMenu(View v){
PopupMenu pop = new PopupMenu(CompanyActivity.this, v);
pop.getMenuInflater().inflate(R.menu.menu,pop.getMenu());
pop.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(CompanyActivity.this,"text: "+item.getTitle(),Toast.LENGTH_SHORT).show();
return true;
}
});
pop.show();
}
The "name" of your ListView items depends entirely on the adapter you're using for the ListView. Keep in mind that the menu item id is unrelated to the listview view id, which is unrelated to the adapter item id. In order for the popup menu to know which item was clicked, you'll need to use the list item position to look it up from the adapter. It'll work something like this:
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
showPopupMenu(view, position);
}
private void showPopupMenu(View anchor, final int position) {
PopupMenu popupMenu = new PopupMenu(
this,
anchor);
popupMenu.inflate(R.menu.menu);
popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
// Depending on what type of object backs your adapter, you may have
// to do something different here.
String title = String.valueOf(mListView.getAdapter().getItem(position));
Toast.makeText(MyActivity.this, "text: " + title, Toast.LENGTH_SHORT).show();
return true;
}
});
popupMenu.show();
}
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

if(isMultipleList){
if(listView.isItemChecked(position)){

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.
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).
