I have an AutoCompleteTextView item in my app layout. I'd like to reserve just a tiny space for it in the layout, so the user can touch it and begin to write. Instead, I'd like that the list with suggested words that pops up is wider, for example like the entire screen. Actually, the pop-up words list is as wide as the textView.
I've found a simple solution. Attribute android:dropDownWidth. For example, I can set android:dropDownWidth="match_parent". Excuse me for posting a question and then founding the answer immediately after.

I'm playing around with Android spinners. I'm not 100% sure if I can get the behavior I want using a spinner, but it's the most obvious choice that comes to mind.
I need something of a dropdown view, the title of which says "x of y selected".
The options in the dropdown would look like:
-All
-None
-Special items only
On clicking one of the dropdown items, the title is reconfigured such that 'x' changes.
It would be ideal to use a spinner, but somehow, it seems that android puts in the first value of the spinner to always be the first values in the list of strings you pass it, and I clearly don't want the title item to be shown in the dropdown list for my case.
Another approach that I came across was to perhaps use a button with a popup with these items in the popup.
Would that be a better approach, or can I actually achieve the behavior using a spinner, or is there another view that would better serve my purpose?
I'm going to redirect to this post, after a lot of searching I found what I was looking for:
How to hide one item in an Android Spinner
The answer by Aebsubis, and make sure to set the text view height to 0. I'll update this answer with more code, once I'm done with tweaking it for my purposes.
I'm developing an application and I am facing a problem using ExpandableListView. What I'm trying to do is, in GroupHeader, not only show the group name, but also an spinner with options. That's because I want to show the football second division games in the list but, also, give the option to choose the round, in case the user wants to check older/future games. SO far I have that
As you can see both, title and spinner, shows. Also you can see the arrow on the right which is supposed to expand the list. Problem is that, if I click, only spinner opens, group expand button doesn't. So, here is my question, how can I make both of them work depending on where you click (one or another)??? Is that possible?
Also I must say that if I only place the TextView with the group name works perfect. If I only place the spinner, the problem persists. So I'm guessing that's a focus problem.
Btw: grey areas are the layout backgrounds, so no, they are not hiding behind the button.
I found the solution, I just neede to add this line android:descendantFocusability="blocksDescendants" to the Main Layout of the xml where I define the GroupHeader elements.
I have used this forum when I didn't know how to do something, but now I have decided to begin participating in it.
I would like to know how could I do a dropdown text (maybe it has a specific name and that's why I don't find any results on the internet). I mean, I have some tags in the screen (About, Company, Contact, ...). Each of these tags has a down arrow on the right side, and when I click it, it has to display (and hide if it's clicked again).
Here are the links with the images of what I want to do.

Thank you in advance!
You should use an ExpandableListView component.
There is a tutorial for it here.
Finally I did it with ImageViews and TextViews using the property android:visibility. Now that it's a static version is working properly. I hope that it continues working well when taking the information from the DB
I'm trying to make iPhone-style EditText element on android.
The one that will have an additional clear button appear on the right after text input.
Adding a new button is not a problem, but I'm a bit stuck with another thing.
A button occupies some space on the right part of EditText, and now characters display beneath the button. How to change maximum shown length of input for EditText?
I want EditText width to be N pixels, and editable area to be N-M pixels.
EditText.setWidth changes width for whole edit box.
EditText.setEllipsize should be the proper solution, but docs are empty, and as I see it truncates text based on some String value.
Applying a LengthFilter cut's the input length to number of characters.
Thanks in advance.
I suspect that android:drawableRight will save you a lot of pain.
Seems I've found a solution.
EditText.setPadding(l,t,r,b) seems to work fine, applying only for editable area
Try this : http://mytechead.wordpress.com/2012/02/07/create-ios-like-cleartextbutton-in-android/
This is a very old question, but thought I'd add my two cents for kicks. I'd probably use a 9 patch for this and set the content area to stop the text before it hits the button area.
This would require creating a custom view so that you can add a button in the desired position using relative layout so that it can be clicked to clear the edittext.
Alternatively you can use the compound drawables, but you would need to implement something like this
Handling click events on a drawable within an EditText so that you can handle the click events. Keep in mind that I doubt the button states (eg the down state) will work using this method.
I have a dialog window that covers 1/3 of the entire screen height and is displayed on top of my activity. The dialog holds two AutoCompleteTextView fields.
The problem I'm facing is that when the user starts typing something into the AutoCompleteTextView, the list with all suggestions only shows up to the bottom end of the dialog, but doesn't go beyond that even the list is longer. It looks like it's cut off. (screenshot left)
Only after I long-press an item from the suggestion list, the list will be shown in full length. (screenshot right)

How to fix this behaviour so that the list shows in full length right from the beginning, when the user starts typing something?
Code-wise there's nothing special, all I do is:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this.getContext(), R.layout.nav_route_autocomplete_row, locStrings);
AutoCompleteTextView txtStartPos = (AutoCompleteTextView) findViewById(R.id.txtStartPos);
txtStartPos.setAdapter(adapter);
...
One workaround idea is to somehow dispatch a motion event to simulate a touch (but then not selecting though) one of the list items. Any concrete idea in code for a solution, anybody?
Right now I'm assuming it's a bug, which I already filed here: http://code.google.com/p/android/issues/detail?id=9917
But if anybody knows a solution to this, I'd greatly appreciate it and would be glad to trade it for some bounty points.
Edit:
One workaround that came to my mind is now to extend the dialog to the very bottom of the screen but leave the background transparent, so it looks the same as now, but actually has a height that wouldn't cut off the list. I will give that a try...
Not long ago i faced this problem. I had small dialog with AutoCompleteTextView, which had more than 10 items in Drop Down list. This list was cutted. My solution was:
Place some empty View in my Dialog layout file with parameters
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!--
Some Views placed here
-->
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="invisible" />
</LinearLayout>
It made my little dialog like a full screen dialog, but actualy that "tail" wasn't showed, and my DropDown wasn't cutted at all, cause it had enough place to show list items from DropDown.
if (yourlist.size() > 5) {
yourtextview.setDropDownHeight(562);
} else {
yourtextview.setDropDownHeight(anytextview.getHeight() * yourlist.size());
}
//Workaround -> Write this condition under on click and on focus change of your autocomplete text view
Just a shot in the dark, but have you tried setting android:clipChildren to false on the view for the dialog atop your Activity?
I have successfully achieved this, but it isn't pretty.
I ended up overriding my SimpleCursorAdapter.newView() method, walking up the ViewParent hierarchy until I reached the root View, and then modifying its WindowManager.LayoutParams by ORing in the FLAG_LAYOUT_NO_LIMITS flag.
This needs to be redone every time the drop down is displayed.
As seen here: Scrolling drop-down-menu over the keyboard in autocompletetextview
You can use the property android:dropDownHeight of the AutoCompleteTextView to force it to be of a certain height. This is not really solving the problem, but is the best I could find.
Note: This problem only happens when using AutoCompleteTextView inside a Dialog. When it is used on the layout of an activity or a fragment it just works fine.
This issue is present all the way from Gingerbread to Jelly Bean.
