I have an activity with a RelativeLayout consisting of a ListView. This ListView is populated through a custom ListAdapter. The list displays a checkbox and text for each row.
So far, so good.
I want to implement something like the default android Gmail app, where if I checkbox-select an email, the titlebar of the application at the top changes and presents options relevant to the selection (such as delete, move, archive, etc). I am not sure what to look for in the Android documentation.
Do I just create some layout above the ListView and dynamically add elements(like delete row, etc) to it on a checkbox click? Any help is appreciated!
if you have used ActionBarSherlock then you can use Action mode menu to show various option to user when checkbox is selected from listview
or
you can try

The attached UI is the calllog. What i am interested is that how the horizontal menu is implemented. When click on one list item, it appeared in one line under the list item.
In the earlier android, one click on list item, we can use Context menu popup menu to show the available action to do.
I am curious that it is using expandable list view concept?
I want to design like that when click on list item to show like this, but my layout would not be the same as this one. I want to put custom layout depending on the list item type. It may include button, textview, other widgets and the layout height will not be the list item height.
Can someone give some suggestion? Thanks a lot.
I have a ListView over the whole screen of the application. To search for list items, I want an input field on the top of the ListView, but it should only become visible if the ListView is scrolled down (like the search field in the email application of the iPhone).
Because it is a ListView I can't create a cell with an input field (other field type like the other cells) in it.
I would be glad if someone can give a hint with which technic I can do it.
Thx.
I'd suppose to use material-design pattern with scrollable navigation bar. There is common template of an application for that purpose in Android Studio
I think you should have a look at SearchView widget :
https://developer.android.com/reference/android/widget/SearchView.html
You try using a SearchView with a ListView. Tutorial link :
http://www.coderzheaven.com/2013/06/01/create-searchview-filter-mode-listview-android/
If you want to hide this then probably make this action menu as invisible and invalidate the options menu and set the visibility true to make it visible on list scroll.
Add a layout above the listview to put in your search edit text (in a linear layout or a frame layout with padding for the list view).
Alternately you could use one of the Design Support Library components and it will be even more well integrated. Then call from your layout to filter the ListView adapter components, ideally with a text watcher or listener that is added to the edit text.
I am making an android application.I have ListView in it which contains four rows having textView i.e

I want to add ToggleButton in ListView for first two rows but don n't want to show it for other rows. How can i customize my ListView in this way.
Any help will be appreciated
You have to write a custom BaseAdapter. There you have the method getView() that is called for each listItem, so this is the right palce to define the layout of the listItems.
Please look at this article to ensure a smooth scrolling of your list.
And you can find a good Tutorial on Vogellas site.
If you want to add toggle button for first two rows only and not for all rows then one easy thing you can do is add in the custom listview layout file both the textview and toggle button but while implementing add (null) in the toggle button's place in the adapter for the rows for which you don't want the toggle button...
I want to have an expandable menu, and when you expand a child item, then it will show some custom items, items of my choice, like a text input field or a checkbox (see the image below).
Now how can I achieve that? Can I achieve that using the Eclipse GUI builder? Or do I have to create methods where the data is loaded dynamically?
UPDATE:
So I do not only want text items as child elements, but all sorts of elements, like an input field or checkbox.
This tutorial works like charm

i also took code from here to make my custom expandable UI by implementing adapter
I'm trying to create a settings screen for an app and I like the Gmail app's settings screens. Here is a screenshot:
It looks/behaves like a custom list of some sort.
The left side looks like a TwoLineListItem (or just a large TextView and small TextView).
The right side is either a checkbox, a blank, or a downward arrow (like ExpandableListView) to indicate you should press it. (ex: when you press the Signature item, a dialog appears so you can input a signature).
I think one tricky part of this is that the entire list item is a "button", meaning you don't have to press directly on the checkbox to check it, you can press anywhere on the list item.
For example, section 5.2 of this tutorial http://www.vogella.de/articles/AndroidListView/article.html requires you tap exactly on the checkbox rather than on the entire list item.
Anyone have any ideas on how this is done?
This is not the 'normal' listView.
That UI was built with the PreferenceActivity
Always use the PreferenceActivity to display settings for your application.
Hi you can easily define an OnItemClickListener with the setOnitemClickListener() method of the ListView. The Listener is called whenever a list item is touched. In the Listener you can either show the dropdown menu or set the Checkbox to 'checked' with the setChecked(boolean checked) method of the Checkbox.
