ExpandableListView has a setOnChildClickListener method, but lacks of setOnChild*Long*ClickListener method.
When I added setOnLongClickListener() on child view in getChildView(), whole sublist became completely unclickable (despite of parentView.setOnChildClickListener() present and working before).
How can I enable long clicks on child views?

i've got an ExpandableListView with my own layouts for the group and child views. a certain group-type will require a different layout. is that possible - i.e. a ELV with different layouts for a group view. i've got my own sub-class of SimpleExpandableListAdapter.
View 6 Replies View RelatedI have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.
Can any one please suggest me how to implement the long click (onItemLongClick()) for the Expandable list view?

I need to completely remove dividers from ExpandableListView. As for parent items it's a setDividerHeight method where I can pass a zero value. But there's no similar method for child divider. Is there any way to hide it?
View 1 Replies View RelatedIs there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.
View 1 Replies View RelatedI have created a custom ExpandableListAdapter and everything works properly. What I'd like to be able to do is in each of the groups add a different type of child to the end. I have tried adding 1 to the getChildrenCount() number and then testing isLastChild in the getChildView() method, but that doesn't seem to work.
If a group has three children what I have working looks like this:
Group
NormalChild
NormalChild
NormalChild
But I'd really like something like this:
Group
NormalChild
NormalChild
NormalChild
AlternateChild
The idea being that the AlternateChild could be a link to more info about the group.
ListView has addFooterView() which will allow you to add a footer to a whole ListView... wonder how to add them to the ExpandableListView's children, or if it's even possible
I have a ListView in my Activity. I am trying to catch both a click and a long click (which should bring up a context menu).
ListView lv = (ListView) findViewById(R.id.MyListView); ... lv.setOnItemClickListener(this); lv.setOnCreateContextMenuListener(this); ...
I notice that if I have both the click and long click listeners up, I won't ever get the long click listener (i.e. the context menu). If I remove the setOnItemClickListener() call, i get a call into
@Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {

I have the following problem: I would like to change value of ExpandableListView's cell on click. How should I do that?
Here is what I'm using:
CODE:............
Application is in progress stage, so attrVal will contain several attributes ( which can be put or not depend on some logic), so I'm using this type of adapter and this way of filling cells' data.
fieldsInList - external variable of LinkedHashMap type.
I have a function which can change one of the member's of fieldsInList variable. How should I notify my expListAdapter or ExpanableListView to be refreshed?

View 4 Replies View RelatedI am facing problem in fixing the child in particular place in views or layout.
1) Can I fix the child at the starting and ending of Layout directly?
2) Can I fix the child at the starting or ending of the view directly?
I have a number of child views, each child is a TableRow and I need to be able to change the order of the TableRows, such that I can swap the rows into any order. I know there is a method called removeAllViews() but I don't really want to remove and re-create the views if its possible to access and change the order. I really want the display to update as smoothly as possible, taking the minimum amount of time, is it possible?
View 2 Replies View RelatedI've been programming in Android for two years now and just joined an Android project where they are using a TabActivity to host multiple Activities. It's unclear why this is better than rewriting the TabActivity to simply use Views instead.
TabActivity extends ActivityGroup which means TabActivity can host both Activities and Views. But what's the use of this capability? I was under the impression that Activities should be treated as individual screens of an application.
In short, what is an example use case where it's recommended that TabActivity should host multiple Activities rather than multiple Views?

I need a LinearLayout to contain 3 TableLayouts, and I can't get it to work. This is where the problem is I'm sure:
mTableLayout.addView(mLinearLayout, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT); mLinearLayout.addView(nTableLayout, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); mLinearLayout.addView(oTableLayout, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); mLinearLayout.addView(pTableLayout, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
How Do I make this work? I can get it to work just find when I only add a single child view, but when I have multiple children view objects my app crashes.
When using a View within a View, for example an ImageView within a LinearLayout, both of which have xml drawable resources (the LinearLayout as a background) specifying PNG drawables to use for the on/off states, shouldn't children Views receive the focus state when their parent gets focus? So as far as I understand, both my LinearLayout and ImageView should be switching to their focus states right? Apparently not Or, more likely, apparently my implementation is incorrect.
The focus state works on the LinearLayout but my ImageView never receives focus.. I have both Views set to android:focusable="true".

This works ok as long as the wordDefinition text isn't very long. But, when I set the text to something very long, it pushes the back button off the bottom of the screen. Why? Isn't the ScrollView supposed to scroll the text in the child TextView?

View 2 Replies View RelatedI would like to capture long click events in a ListView, which was easily done using a OnItemLongClickListener.

Everything I am doing through Java programming (instead of XML layout, because number of TableRows changes each time) On next screen, I wanted to display all the views of that particular clicked TableRow. Here the problem i am facing is how to capture particular tableRow on onclick() even and how do I get all the textviews of that particular Row. I tried to set id at runtime, and tried to get id of view, but it's not working, giving error resourcenotfoundexception.
View 2 Replies View RelatedThe context menu is not popping up on the long click on the list items in the list view. I've extended the base adapter and used a view holder to implement the custom list with textviews and an imagebutton. adapter = new MyClickableListAdapter(this, R.layout.timeline, mObjectList);
list.setAdapter(adapter);
registerForContextMenu(list);
Implementation of onCreateContextMenu
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
// TODO Auto-generated method stub
super.onCreateContextMenu(menu, v, menuInfo);
Log.d(TAG, "Entering Context Menu");
menu.setHeaderTitle("Context Menu");
menu.add(Menu.NONE, DELETE_ID, Menu.NONE, "Delete")
.setIcon(R.drawable.icon);
The XML for listview is here
<ListView
android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
I've been trying this for many days. I think its impossible to register Context-menu for a custom list view like this. Correct me if I am wrong (possibly with sample code).Now I am thinking of a adding a button to the list item and it displays a menu on clicking it. Is it possible with some other way than using Dialogs?
I have a list using a customized BaseAdapter. When one element of the list is hit during a long time, a contextual menu appears. I want to use this one to delete or edit the selected item but I don't know how to get id or anything else that could help me.
I tried getListView.getSelectedItem() thinking that it will give me the object returned by the method getItem(int position) inherited in my customized BaseAdapter. I got null. When I tried getSelectedItemId(), I got -1.
Does someone have a solution?
I think everything is in the title. I have been searching for this problem for days, seen the question asked everywhere, but never answered. SO maybe someone here knows how to do that.
