There is this one Android app called Out of Milk that has a menu appear above a selected item in a list view, I was wondering how would I do that for my list view?
Here's a picture of what I'm talking about:
This is called quick action. You can check this link to see how it is done.

I am working on xamarin.forms. I am creating an app for android. In app I have a dropdown list. I am using Picker for it. I customized it to look like dropdown. Now I need to make the first Index item to nonselactable. Means user can not select the first item. If user click on it nothing should happen. But currently when user click on the first index dropdown gets collapsed.
One more thing that I have to add in dropdown is a Cross button at index 1. Means at index 1, on left side there will be Cross button and at center there will be text like Select item. And this whole row should not be selctable. If user click at cross button dropdown should collapsed.
Anyone have idea how I can do this?
You can use listview for dropdown and control its visibility as per need.I faced similar situation where I customized list view to enact dropdown.There is another thing I want to know about Picker.Does your picker accepts or adds string only or you could customize it to accept views or controls?
It receintly came to my atention that Whatsapp introduced phonecalls within their app. I liked the way they added a button inside the list item and are able to distinguish the clock icon clicks from the "rest of list item" clicks. Next you can see the list with its list items.
My question is how do I differ those clicks. I can ceirtanly add a ButtonView to my list item layout file but when I do that my fragment's OnItemClickListener does not even trigger. If anyone knows how to achieve this, I would really appreciate it.
Again, I'm handling the actual item click events from my Fragment, not from my Activity.
I have an app that has a ListView and when I click on some item, it adds the item in an array.
But when I click on some item I don't want change the view, then in Android 4.0 the ListViewgoing to first, but in Android 4.2.2 the ListView doesn't change. Why?
I always want the same result, the second option.
Is there any property for this?
Try making use of the getFirstVisiblePosition() and setSelection() methods of the listView. The first gets the first listview item present on the screen and the second moves the listview to the proper index when you comeback to this activity.
Please read the documentation for some more details about these functions.
I have a ListActivity that presents a list of names from a database using a SimpleCursorAdapter. I want the user to be able to select 1 or more names by clicking them and then proceed to the next Activity. This should be a toggle, so that if the user clicks a selected name it will become de-selected. The underlying code is working fine, the problem is how to show the user which items are currently selected.
I looked at this solution: Android how to highlight a selection in a list and tried toggling .setSelected() on the TextView for the name. The problem is that the "selected" state apparently can only be true for one item in a list at a time. So if the user touches "Alice" then "Bob," only "Bob" will show as selected. Any thoughts on the best way to have a toggle-able highlight for multiple list items?
Have a look at the setChoiceMode method of the AbsListView class and its possible CHOICE_MODE_MULTIPLE parameter value.
I want to display a list item that says "More" at the end of my ListView. Clicking on this list-item will perform some action. How can I create this "more" list item?
I don't know about the "Clicking on this list-item will perform some action" part. The typical pattern is that once the user scrolls to the bottom, new material is loaded automatically. Some people do that by detecting the scroll. I do it by putting in a "More" placeholder and detecting when that is used. Here is a component that implements this pattern.
Just add another value to your arrayadapter (or any other adapter), you might be using.set the text to 'more' .
Suppose you have n items in the list then handle the (n+1)th postion click and do your stuff.
You can add a footer to your listview...
