I've created a custom IME for Android tablets and I'm having trouble resizing when the screen is in horizontal orientation. Whenever an EditText is clicked while the screen is horizontal, the IME takes over the entire screen with the standard EditText and Button combo with my custom IME at the bottom of the screen. However, I'd like for the IME to simply pop up without that and type directly into the field that was originally clicked, as it does in horizontal orientation. I've looked at the SoftKeyboard example, which accomplishes this (at least on honeycomb) and can't find exactly where they are setting that effect.
Sorry if this is a duplicate, I've tried searching but couldn't find this exact question.
If anyone else is having this issue, you can prevent your IME from entering fullscreen mode by overriding the onEvaluateFullscreenMode() method, which is what determines whether or not your IME will display in full screen.
Now I'm having different issues but that's for a different thread!

I am developing an application for android devices, which manages TV channels and shows. In it there is an option for the user to add channels in the system using a custom widget. The widget uses autocompleteTextView. My layout does not adjust itself when the soft keyboard appears.
These are the 2 states of the layout:
The keyboard blocks the user from viewing the options in the dropdown and the field below it. I have already tried the solution here and here. But none of them got it to work.
I want to move the layout of the widget itself, rather then the whole layout behind. How to go about this problem?
As shown in the landscape images here: http://android-developers.blogspot.com/2009/04/updating-applications-for-on-screen.html .
I don't necessarily need to do the fullscreen thing, but my issue is that the EditText is below the soft keyboard and I cant figure out how to get the whole thing to display above it. Its a note field, and fills whatever open space there is from the end of my other fields to the bottom of the screen. Currently when I select the note, the screen moves up just enough to see the top of the note field, but this is not good enough. I want the top of the note field to move up to the top of the screen, to maximize what the user sees while they are editing the field.
My softInputMode in the manifest is adjustPan, but changing these settings has not done anything for me.
You need to add a ScrollView around the view to make it slide and change adjustPan to adjustResize (adjustPan is normally not recommended) to the activity on the manifest.
i have an activity with an edit box, when the user touches inside the edit box, the soft keyboard comes up. if the user presses the hardware "back" button, the soft keyboard goes away. I want to detect this situation. I have looked around and the best response i've seen so far is this one:

my question is -- how can you detect if your application window has been resized?
I added this text to my activities in my android manifest file:
android:windowSoftInputMode="adjustResize"
but I'm not quite sure how to detect the change.
any help greatly appreciated.
Android does not provide an API for checking if the keyboard is visible or not. You can, however, key off the height of your top level layout to determine this information.
First, you have to set your activity's android:windowSoftInputMode attribute to "adjustResize".
Then, create a new class that extends your desired layout type (eg LinearLayout). In that class, you can override a few different methods that will be called as the height of your layout changes (due to the keyboard being shown or hidden). When these calls are triggered, you can compare the height of your layout to the height of the screen. If there's a substantial difference between the two (ie more than just the size of the notification bar), the keyboard is visible.
Finally, make sure that you use your new class as the top level layout in your layout xml (eg in place of LinearLayout).
If you would like a more thorough explanation, I've written one up: http://www.cannedcoding.com/2011/08/soft-keyboard.html
Creating an Input Method Service (See http://developer.android.com/reference/android/inputmethodservice/InputMethodService.html) to listen for the back button might work. When it is pressed, you can pass that on to your activity which then does what you want it to do along with removing the soft keyboard.
I have a layout which has one large EditText view at the top + a bunch of buttons at the bottom. The EditText is made to shrink and expand when the ime is activated/deactivated by using adjust_resize. The buttons at the bottom are pushed up above the ime.
I would like to hide these buttons when the ime displays, to provide enough space for the EditText view.
I have so far tried the following:
subclassed EditText and provided the activity the option to register a callback on the view's OnSizeChanged.
Used this callback to change the visibility of the buttons (actually the layout container) to GONE.
This work OK and does hide the buttons when the ime pops up.
However, the EditText does not expand into the new available space.
Furthermore, when the ime is disposed off, the EditText field is now bigger than it was originally, pushing (the now showing) buttons outside the screen.
I should also add that when typing the first letter into the view, and the ime displays the word options, the screen is redrawn and the EditText fills the vacant space.
Any ideas on how to get this to work?
Or even better, is there a simpler solution to my requirement?
Thanks...
NB: In my view, scrolling is not a good option.
I got this to work by changing the above method a bit:
Wrapped the entire layout with a FrameLayout
subclassed the FrameLayout and provided the activity the option to register a callback on the layout's OnMeasure
This gives the activity a chance to change visibility of views before these are measured.
I would still be very happy to hear about simpler solutions, especially in regards to figuring out whether the keyboard is currently visible or not.
(dumpsys window shows this information. Can we easily get to it?)
Have you tried to call myView.invalidade() ?
I was using the GONE property, but then changed to button.setVisibility(View.INVISIBLE); because I don't have any other stuff on my screen.
on the adjust_resize, you will need to check again when the keyboard has gone and show the buttons again.
In my android application, I have an EditText. When I click in this field, the soft keyboard appears, expanding from the bottom of the screen. It seems to actually modify my layout, pushing contents upwards. When I dismiss the keypad, it retracts, and I see my layout re-expand to take up the space it previously occupied.
Is there a way to get the keyboard to simply appear "on top" of my layout, so that I don't get this somewhat unpleasant relayout animation? The EditText is pinned to the very top of the screen, so I don't have to worry about the keypad hiding it.
Thanks
By default, Android should be using "Pan and Scan", which would work more or less how you described. The keyboard is displayed over your view, and you can scroll your view in the background. If you override the windowInputMode for you Activity, or Android determines that your Activity is resizable (because of the presence of a resizable field... ListView, ScrollViews, etc), it may resize your view instead, and it sounds like that's what you're running into. To force it to Pan and Scan try adding:
android:windowSoftInputMode="adjustPan"
as an attribute to the Activity element in your xml layout.
There's a third option as well. You can specify that when an EditText is selected it will be edited in full screen mode. The other controls in your view will be hidden, the user will be presented with just the keyboard, an EditText control, and optionally some other limited controls. If your EditText doesn't require a lot of context from other elements of your view, it may prevent a cleaner user interface. For more details, see: http://android-developers.blogspot.com/2009/04/updating-applications-for-on-screen.html
Add:
android:windowSoftInputMode="adjustResize"
to your activity attr in manifest.xml. Hope it will help.
This questions seems to state a resize is not desirable. I had the same issue, but adding
android:windowSoftInputMode="adjustNothing"
to the manifest file instead solved my problem.
