I am making a app, where my fragment layout has three part- header, content part(ListView),
footer(a EditText).
I wanted to take the editText to up as the keyboard is opened. So, I set androidWindowSofInputMode="adjustResize" But it is resizing complete layout, Besides, just resizing the ListView, Since, there is a wallpaper on my parent view, and it gets shrinked due to complete layout getting resized.
I see in apps like WhatsApp and hike that only EditText goes up and the chat wallpaper remains as it is(not shrinked).
Use adjustPan instead. It does exactly that.

Hello I want to add a LAyout to my Activity.
I have a FrameLayout where I add a SurfaceView so far.
Now I want to add another Layout as a menu over it so when I click a Button on my Surface View I set it to be Visible.
This layout should contain one Textview and should be scrollable
1: What is the best LAyoutout thing for this approach? I thought of a Listview where I add Strings dynamically
2: How can I achieve this in Code?
It should be:
Scrollable.
Should be a certain Size: Half of the screen width and half of the screenHeight
So it also should be at the position screenWidth/4 and screenHeight/4
To achieve this I can set these parameters inside my mainThread that is attached to the surfaceview so I have the parameters needed allready in Pixel format that's no Problem.
It should loose the Focus when the User taps outside of the view so my surfaceView gets the Focusagain and set the LAyout to Gone.
So it should go like this:
User taps the button to display the menu
Now the User can scroll through the Menu
When he presses the Backbutton or outside of the View It should close itself
When there is a new Text that should be displayed it should be attached to the layout to be ready to be displayed at the next time the user clicks the button again
Thank you

That sounds good to me, you can go with either ListView or RecyclerView. You are basically not adding TextViews dynamically, you create an adapter that will do handle creating and recycling of views for you.

Create a DialogFragment, it's the best candidate for such dialogs with logic. Its lifecycle is handled via FragmentManager, so you won't have issues on screen rotations and so on. It allows you setting whatever layout you need just like any other Fragment. It will be placed in the center for you, so you don't have to handle that manually. Just set the size of the dialog you want and it will look perfect.
It should loose the Focus when the User taps outside of the view so my surfaceView gets the Focusagain and set the LAyout to Gone.
I don't really get this one. When user touches outside, do you need to lose the focus but the dialog should not be closed? If yes, then this is already answered here:
Allow outside touch for DialogFragment
If the dialog should be closed, you don't have to implement anything, it works like that by default.
An EditText at the bottom of a ListView when pressed, hides the ActionBar. My first problem was to prevent the background image of ListView to shrink. Somehow i overcame my issue. But dnt know how to tackle this one. Can any body guide me? Thanx in advance.
Edit(Explanation)
like a chat window in Viber or Whats App, i have a EditText at the bottom, a ListView in the center and an ActionBar at the top. when i clicked the EditText , the background image shrinks/squeeze. I used adjustPan to overcome this. Its fine. But now, when the soft Keyboard appears, it hides the ActionBar/TitleBar.
Use adjustResize instead of adjustPan. The framework will always try to keep the focused element on-screen by scrolling any parent views if necessary.
If your EditText field is not nested in some sort of scrolling container such as a ScrollView then your layout may be too tall to completely display when the keyboard resizes your activity. Try wrapping your form's layout in a ScrollView. This will also allow your app's content to scroll if it is running on a smaller screen device where it may have similar issues.
Had a question about making part of a View Always-On-Top. Please see the Groupon picture below. The black window at the bottom where it says "From $29" & "Buy!" is always on top of the activity page. Meaning the rest of the page is scrollable above that black window at the bottom. Please note I only want this activity to have an Always-On-Top
How do I make a portion of the activity Always On Top? And what kind of layout did you think they used for Groupon? I was just going to make a RelativeLayout and layout_alignParentBottom="true".
You could probably get away with having a vertical linear layout with two children. The first one a scrollable area and the bottom a view with whatever it is you want to be 'on top'. Since there's no transparency there's no visual difference between having the black view as always-on-top and having one view on top of the other (in the y-axis, not z-axis). Plus, if you do it this way you can reach and see the bottom of the scrollable view's content.
To the best of my knowledge, the best way to do this is by implementing a BaseActivity with this View, and have all your activities extend this activity instead of the standard Activity.
I would like to change the layout when an EditText is clicked and the softkeyboard is shown, so all EditText views are still visible.
I know that you can use the following two, but this is not what i'm looking for.
android:windowSoftInputMode="stateUnchanged|adjustPan">
android:windowSoftInputMode="stateUnchanged|adjustResize">
I've got 8 EditText views spread over the whole screen. When one is clicked to change a value I would like to still see all the ET views but nicely arrange and not pushed in a weird view.
Is there an easy way to do this?
I think you are going to have to do this yourself, but one technique might be ...
Create a layout with the views arranged for the keyboard shown (for instance a new RelativeLayout) that overlays your standard layout. Set it's visibility to GONE. Then when you detect the event that shows the keyboard hide the current view and show the alternate one
I suppose you could also use a ViewSwitcher
If you are using both at the same time then it doesnt work.Set the attribute android:windowSoftInputMode="adjustPan" only.That should work.
I have a ListView and each item contains a TextView displaying a number. I'd like to give my users the ability to change this number while staying on the ListView (as opposed to drilling down into a detailed view by clicking on the list item).
What I'm looking to do is to slide in a layout from the bottom of the screen that covers about half of the screen. I'd like this layout to be OVER the Activity behind it (as opposed to being part of that Activity's layout and simply showing it). I'd also like it to be model (or seem modal). Meaning the Activity behind it can not be focused and manipulated. In this layout I will essentially create a calculator.
What I need help with right now is:
1) How to display a layout over the current Activity
2) How make the background (the Activity) modal
Could someone point me to some tutorials/resources and/or give me a few tips?
use an Animation. here is a small tutorial on them: http://developerlife.com/tutorials/?p=343
initially, the view you want to be modal must be placed where you want it to show up(and visibility set to gone).
use a translate animation to visually move the view from below the screen to halfway up the screen. once the animation starts, set visibility to visible
try disabling all views that the user should not be able to interact with after you have started the animation holding the calculator view
