Android :: Expandablelistview Won't Work With Context Menus / Why Is So?
Oct 3, 2010
My app used to use a standard ListView, and registerForContextMenu(getListView()) and everything worked just fine.
I needed to change my app to accommodate nested lists so I replaced the ListView with ExpandableListView. I changed the Activity to ExpandableListActivity. I also changed my adapter to a tree adapter and implemented a custom view class to populate the list with (based on a FrameLayout view).
Suddenly my context menus stopped working and I can't figure out why. I can't long click on any of my list items and I'm completely stuck on where to start looking.

I want to view two listviews at the same time. This is not the problem!
What I don't know if it's possible is if I can have two different context menus for the two lists? And second, is there a way to check in which of the two lists the user has selected an item?

How could I capture an onListItemClick() and pass it to onCreateContextMenu()? In my ListActivity, I don't need regular clicks, so I'd like everything to go to the context menu.

I'm trying to add a context menu to my ExpandableListView. I've implemented onCreateContextMenu() and onContextItemSelected() but if I hold my finger on a menu item context menu doesn't appear. What's my mistake?

Can I somehow change color of texts in context menus? It has white color and the background is white too, so I can't see the text.
I'm using this ROM on my Xperia X10 Mini Pro.
I'm attaching some screenshots for better explaining of my problem.

I try to build a ExpandableListView with a own ExpandableListAdapter but the ExpandableListView is not visible in my activity
Below you find my Source-Code...
Here the Code from the activity:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.group_main);
onCreateDBAndDBTabled();
mAddGroupButton = (Button) findViewById(R.id.Button_Add_Group);
mAddGroupButton.setOnClickListener(this);
mExpandableList = (ExpandableListView) findViewById(R.id.ExpandableListView01);
ArrayList<ExpandableListItem> valueTree = new ArrayList<ExpandableListItem>();
ExpandableListItem gp1 = new ExpandableListItem();
gp1.putProperty("name", "e");
ExpandableListItem gp11 = new ExpandableListItem();
gp11.putProperty("name", "l");
gp1.addChild(gp11);
ExpandableListItem gp2 = new ExpandableListItem();
gp2.putProperty("name", "A");
ExpandableListItem gp22 = new ExpandableListItem();
gp22.putProperty("name", "B");
ExpandableListItem gp23 = new ExpandableListItem();
gp23.putProperty("name", "A1");
ExpandableListItem gp24 = new ExpandableListItem();
gp24.putProperty("name", "A3");
ExpandableListItem gp25 = new ExpandableListItem();
gp25.putProperty("name", "A4"); Code...

I am trying to write an app which has an ImageView and the app allows to perform panning on the image. I also want to register context menu with this ImageView so that on long press Context menu comes up. I tried playing around with the onTouch method, but could not get it working.
On long press, i do see context menu. But, while panning also the context menu comes up. I want that context menu is displayed only when long press is performed and not while panning. If I return true from the down event, the context menu fails to come up.
Please find the snippet of the code below for the reference. Code...

I'm working through the 'notepad' tutorial given in the developer's guide: http://developer.android.com/guide/tutorials/notepad/index.html
For some reason, even when i'm using their solution files, the context menu does not come up with i 'click and hold' on a list entry.
The class extends ListActivity, and calls "registerForContextMenu(getListView());"
but I never see the context menu fire. Any idea what's wrong with it?

I am really struggling with linking menus together. The app I want to create is a collection of menus that leads to url links to various sites I plan to open within the application. I have created a list activity menu with 8 options and I have eight classes with further options. My problem is how to link the menus together. I ask the question and someone said that I should map. Here is the code:
public class MyList extends ListActivity {
private static final String Cp = null;
private static final String Pp = null;
private static final String L2 = null;
private static final String L1 = null;
/** Called when the activity is first created. */
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
// Create an array of Strings, that will be put to our ListActivity
String[] names = new String[] { "Pp", "Cp", "L1", "L2", "Bt", "Se", "As", "Travel"};
// Create an ArrayAdapter, that will actually make the Strings above................

I have managed to create a menu with four options. I want to create four sub menus of same style for each option.In my infinite nooby-ness I have created four classes for the sub menus but I cannot figure out how to move between the menus(Classes).For instance I have four options Prem, Champ, L1, L2, I have created the Prem sub menu but how do I get the program to move to this class(SubMenu) when the Prem option is selected, and how do I get it to move back.

I need a very simple menu which probably contains only one or two items: settings/options, where pressing one of them should show some customer defined parameters (is it called dialog), e.g., number of results shown. Is there any good tutorial on creating such kind of menus? I've looked at the "notepad" example in android, it doesn't really help.

wanted to add a menu option in native email app in android . I have used intent filters but i am not successful in achieving it. Actuaaly i want to a menu option to the native mail application in Android.. so that my activity / app can be launced on clicking that option. This feature has been successfully achieved in Blackberry and even in android for gallery application. On android i have achieved it by using intent filters.
<activity android:name=".DisplayAlternativeMenu"
android:theme="@android:style/Theme.NoTitleBar">
<intent-filter android:label="My Activity">[code]....
This basically display an menu item"My Activity" when u press share in Gallery. and clicking on that launches my activity .But unfortunately it didn't work for Email Application. Looks like the pair of action & mimetype i am specifying is not correct. which action & which mimetype should be used. Also if there are any permission required,what are they?
My aim is to add an alternative menu while pressing menu in Compose Email(When a mail is composed) of the native email application

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 want to show a menu similar in look and feel to the sub-menus. I want the menu to come up when we tap on the screen. Is it possible to have sub-menus displayed without creating the main options menu? I do not want to use context menus for this.

I have an expandable list view with a static array for the group data and an SQLite database for the child data. It is implemented with the BaseExpandableListAdapter and works great, except, when I edit the database to delete or add children to the list I do not see the changes onscreen. It looks like I can use the registerDataSetObserver method to notify the adapter and expandable list of a data change. What I have to do in the callback to make Android redraw the list after data changes is what I need to know. Can I do it? Documentation on this part of the SDK is a bit sparse and expandable list view example code is not a good match. Can anyone offer advice on how to use a DataSetObserver? It feels like I have to switch over to a Cursor type adapter.

This is my ExpandableListView
CODE:..............
When I execute this in emulator, green(childDivider color) is all over the place.
It seems if childDivider is ColorDrawable, it has no bound.

I tried to use the built in list filter using:

The above code does not work for filtering.
How can I implement the search/filter functionality?

I upgraded to 4.4 last night. Overall, it seems fine to me but one thing that annoys me is that the menus have slowed down. I'm not sure what it's called, but I'm referring to the menu that you can drag from the top of the screen (I'm using a Galaxy S3) by swiping your finger from the very top of the screen downwards. Has notifications and all the enable/disable icons for the various services. Used to be fast when I would swipe my finger down rapidly, now it lags. Wonder if there is any way to fix that, or if it's just part of 4.4?

I have an ExpandableListView bound to a SQLite database. To simplify things, lets assume the database contains two columns: title and body. In the ExpandableListView, there is a group for each title, and a childfor each corresponding body.
Now to make things more interesting, some of the rows in the SQLite database do not have a body (that is... they only have a title). As you can see, if there is no body, then there is no reason to expand the group... because the child will be empty (i.e. String body == "").
I'm searching for a way to catch a situation like this, and skip the group's expansion. I don't want a blank child to be expanded. To put it in psuedo code, I want something like this:

My problem is when I want to refresh data in ExpandableListView while being in that current activity. I create adapter and when I want to add new data to list I call again constructor of that adapter(it is my private variable) with all new data....and then I call onContentChanged() method to redraw my list.
But what happens is that I cant expand my list any more...like it is blocked or something and logcat isn't saying anything...
This is the code that i call after setting new data in arraylists and maps:
