Android :: Identifying View Selected In Context Menu
May 28, 2010
In Android, onContextItemSelected has a single MenuItem argument and so it isn't clear how to identify the view selected. MenuItem.getMenuInfo provides access to Contextmenu.ContextMenuInfo, but while both known subclasses provide access to the target view, there does not appear to be an accessor on the interface.One alternative is to save the View provided in onCreateContextMenu in a private class variable which relies on onCreateContextMenu not being called again in the activity before onContextItemSelected. Another is to use the id of the View for the itemId argument of ContextMenu.add. If we do this, we would then need to identify the option selected from the context menu by using its (possibly internationalised) title.what is the best method for identifying the View selected in onContextSelected?

I have a View that extends Activity. A ListView will display a number of listitems. When the user long clicks I would like to present them with a contextmenu allowing them to select edit, delete etc. and then identify the listitem that was selected as the item to perform the action on.
In onCreate I have:
listView.setAdapter(adapter);
listView.setOnItemClickListener(onListClick);
listView.setOnItemLongClickListener(onListLongClick);
registerForContextMenu(listView);
I have a method onCreateContextMenu
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.setHeaderTitle("Context Menu");
menu.add(0, v.getId(), 0, "Edit");
menu.add(0, v.getId(), 0, "Delete");
and also onContextItemSelected
@Override
public boolean onContextItemSelected(MenuItem item) {
if (item.getTitle() == "Edit") {
// edit action
} else if (item.getTitle() == "Delete") {
// delete action
} else {
return false;
return true;
}I am not sure where to go from here to get the correct row/listitem.

Context Menu seems quite handy as long as we are using an AdapterView as we can easily get selected item position in onContextItemSelected from AdapterContextMenuInfo.position Any idea how we can achieve something similar in a TableLayout? In my TableLayout, i have some TableRow and i would like to get the row index in the onContextItemSelected callback like i would do with a simple ListView. I guess i will have to register the contextmenu for each row? but how can tie the row index with the menu? i see no way to do it with registerForContextMenu.

How can I open a context menu for a view without registering it using registerForContextMenu()?
My activity overrides onTouchEvent to detect motion, and if I use registerForContextMenu() it stops working. I'm detecting a long press, so I'd like to forward that request to a method that would build the menu for me, but don't know if it can work that way.

Trying to set ContextMenu title according to the ListView clicked item.The ListView contains Bookmarks list -> FAVICON + BOOKMARK TITLE @Override public void onCreate Context Menu (Context Menu menu, View v, ContextMenuInfo menuInfo) {super.onCreateContextMenu(menu, v, menuInfo); menu.add(0, EDIT_ID, 0, R.string.menu_edit); menu.add(0, DELETE_ID, 0, R.string .menu_delete); menu.add(0, SHARE_ID, 0, R.string.menu_share); AdapterView. Adapter ContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)menuInfo; View itemID = (info.targetView); menu.setHeaderTitle("bla" + itemID);when I run this code it shows the android.widget.RelativeLayout@423d2389 or whatever and if I change the itemID to String itemID = ((TextView) info.targetView).getText().toString(); I get force close on long click even though no errors are shown in Eclipse or when I run the app.I also want to get the favicon in the same way.

I have a tab activity with three tabs and I want to display a listview in each tab. The list populates correctly, but for some reason I can not get the context menu or itemclicklistener to recognize gestures on the listviews. Anyone have any ideas why this might be? Below is my onCreate method: @Override public void onCreate(Bundle savedInstanceState) { super. onCreate (savedInstanceState);setContentView (R.layout.armory_header); TabHost mTabHost = getTabHost(); mTabHost.addTab (mTabHost. newTabSpec ("1"). setIndicator ("Weapons"). setContent (R.id.page1)); mTabHost.addTab (mTabHost.newTabSpec("2").setIndicator( "Armor" ).setContent(R.id.page2))TabHost.addTab(mTabHost.newTabSpec("3").setIndicator("Accessories"). setContent (R.id.page3)) ; weapons = (ListView) findViewById(R.id.weaponlist); registerFor ContextMenu(weapons) ;weapons.setOn ItemClickListener (new OnItemClickListener(){ @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {// TODO Auto-generated method stub listId = weapons.getId(); position = arg2; showDialog (DIALOG);armor = (ListView) findViewById (R.id.armorlist) ;register ForContext Menu(armor); armor.setOnItemClickListener(new OnItemClickListener(){ @Override public void onItem Click(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub listId = armor.getId();position = arg2; showDialog(DIALOG);

How can I launch a contextmenu from a contextmenu? I'm trying to replicate the MediaPlayer action that happens when you long click a song, then click "Add to playlist" in the resulting contextmenu. When you click that menu item, another contextmenu pops up with "Add to playlist" as the title, and "Current playlist", "New", and however-many-playlists-you-have defined after that.

I'm trying to add custom menu items in a WebView Context Menu. Unfortunately, my items are shown in the menu of the first web page I load , but then if I load a second page, a long press only shows the standard context menu items. Mine are gone. I've put a Toast inside the code and it is displayed as well on the first loaded page, but not on the second. I'm using the code below:..............

I am creating a context menu in separate class from the listview, because the contextmenu will be access by several listviews in different classes. Whenever I long-click the listview, contextmenu pops up, but nothing happens when the options were chosen. Tried to look at logcat message and it said something like this:
Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@43c488f8
Any idea what really causing this problem? cause it works perfectly fine if i put the contextmenu on the same class as listview.

i have got a stupid question to ask. I created a custom ContextMenu. But when i call the menu, the menu displayed will also have the default menu added in. Is there anyway for the default ContextMenu not to appear as well?Code requested: @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo)
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
menu.setHeaderTitle("Recipients");
inflater.inflate(R.menu.menu_contacts, menu);

I have a ListView with a ContextMenu, it has one CheckBox (the CheckBox has android:focusable="false") and one TextView per row, but you can hide the TextView in the preferences menu. After doing that, the CheckBox wasn't registering the ContextMenu, so of course, why not register For Context Menu(cb) and unregisterForContextMenu(getListView())? Yes, i did that, but then, when when i call the delete command of onContextItemSelected, the app crashs. AdapterContextMenuInfo info=(AdapterContextMenuInfo)item.getMenuInfo(); db.deletarTarefa(info.id);

I have a context menu option that, when clicked, will load some information from the web and insert it into a database.So this is a lengthy process and I would like to display a progressdialog over the top of the context menu when this option is selected.I've got the progressdialog running now, but it won't show up.It's almost like the context menu is covering it.So is there a way that I could get the progressdialog to show up on top of the context menu and be visible to the user.

I have a ListView with 5 items. Each of the items can be long pressed to open a Context Menu. The Menu has 5 options and I want them to be selectable, by having a check box. I know of the multiple choice listview but was not sure how to have this checkbox feature in a ContextMenu.Does anyone know if this is possible and if so, how?

I have a context menu that starts to do some calculations when you press one of the context menu items.While the calculations are made I have a progressbar that I want to show. The progressbar is called from the calculations() method. The problem is that I can only see the context menu while the calculations are being made and the phone is more or less frozen.

if google voice is installed on your phone, when you dial a phone number a context menu pops up asking if you want to dial with or without google voice. I would like to accomplish the same task for dialing a number or sending a text message. Does the API allow you to do that?It seems there is a process_outgoing_calls, in the permissions manifest, but is there anything for the SMS?

I have a ListActivity with a list of names (Jacob, Will, Matt, etc.). I have a contextMenu which gives the user the option to edit or delete the person. I know how to find the id to perform the edit and delete functionality, but I can't figure out how to get the person's name to be added to the intent extras or to add a toast when a delete occurs.
Here is a snippet of code that I'm using for the context menu: Code...

I've been working at this all day, and I'm really close but just can't get this to work. I have a button that pulls up an AlertDialog populated with saved entries that include Name and Price. Right now, I can click an item in the Dialog and have it automatically fill in the Name and Price fields in my activity. I want to also be able to long press an item and receive an option to delete it. This is my first try at an Android app, and a lot of this is repurposed from the Notepad Tutorial. Two things I can't figure out:
1) Is my registerForContextMenu sufficient/correct?
2) What am I doing wrong with my onCreateContextMenu? Code...

I have two activities that both contain an identical context menu built programmatically using menu.add(int, int, int, CharSequence). They both use onCreateContextMenu and onContextItemSelected.
The first Activity contains a ListView, when the user long presses on an item the context menu appears for that item. The second Activity (a detail screen for each item in Activity 1) contains a button, when the user presses the button the context menu appears.
I'd like to share the code that creates the context menu between these activities. The only thing these activities share is the context menu, so it seems like a bit of overkill to create a superclass (e.g., ActivityOne extends ContextMenuActivity) that defines onCreateContextMenu and onContextItemSelected methods.
Is there a better way of sharing these methods between activities?

Having a little trouble working out how to have a context menu working in my GLSurfaceView view. There doesn't seem to be a "onCreateOptionsMenu" or "onOptionsItemSelected" to override. I do notice a "setOnCreateContextMenuListener" but I don't know how to use it.

While Contextmenu items support calling setIcon : menu.add(0,).setIcon( R.drawable.xxx); the icon never gets displayed. Is this a bug? a feature? Is there a reasonably priced workaround for getting icons onto context menus?

I'm writing a program where the user's finger will often linger on the screen for more than the couple of seconds it takes for the context menu to activate. I have a class that controls when this should happen, but I seem to be unable to launch the context menu manually. As a last resort I decided to register the context menu just before running openContextMenu(View) and while this /did/ grant me a context menu, it subsequently disabled the calls to onTouchEvent when the user touches the screen, rendering the program unusable after showing the context menu. What is the correct way of manually opening the context menu? Why does onTouchEvent suddenly stop receiving events?
