SoftKeyboard pushes all the views

I'm trying to make a chat layout. The problem is when I focus the EditText, softkeyboard appears and pushes everything up. I want it to push only bottom part with send instructions so that top (brown) header part and a recyclerview with messages are still visible. Something that facebook messenger app has. I tried putting "adjust pan, resize" and everything in manifest file, but it didn't work. Here is my default layout when nothing is in focus:
And this is when I press the EditText and keyboard appears and shifts everything up:
I can't see header anymore nor the message in recyclerView.
Basically I want all elements to stay visible at all times, so when Keyboard pushes up, header, messages and send are still visible to the user.
Here is my layout code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

use android:windowSoftInputMode="stateHidden" in your activity at manifest

The issue was that I was using a theme in my App activity that was fullscreen. When I removed fullscreen from main base theme, it's working.

How can I prevent FrameLayout from shadowing my Views?

My interface looks like this:

Now, you can see at the bottom there is I am here to.... This is a dropdown and when I choose one of the options, my code dynamically adds a few views to the hierarchy but the problem is they are not visible(not all of them; just I am a... is visible.)
I checked the layout hierarchy through the Layout inspector and turns out that the hierarchy is alive but the floating button(Create Account) has overshadowed it.
Now, I know if I were to replace the root FrameLayout with a LinearLayout, it would be visible but the problem is that if then I would click on a EditText button, the keypad would cover the screen with the Create Account button as covered too. I actually want this button to be on the screen at all times.
Does anyone how can I get around this problem?

Your layout is not totally correct because your floating button hides the bottom of your ScrollView all the time. You should replace the FrameLayout with a vertical LinearLayout (just like you said) and then specify the window behavior of your activity when the soft keyboard pops up with the windowSoftInputMode attribute in your activity element on the AndroidManifest.xml file. If you use android:windowSoftInputMode="adjustResize", the window will resize accordingly and the button should be always visible.

view sliding over layout

I have relative layout. Within which I have many views like edit text, text views and so on. I do lots of animations in that. Everything was perfectly fine. But at one point, I have a requirement.
It is the password page. Create and confirm password. Two edittexts one after another. If the password doesnt meet the requirement, a plain orange view should slide up with error message "Invalid password".
So I put create and confirm password in linear layout. The linear layout will slide up, letting user type in passwords. After validation, if there is an error, the linear layout should slide down and the plain view will slide up. I kept the view invisible and when required I made it visible and wrote the code to slide up. The same code works when I just use single edit text instead of linear layout. But it is not working when using linear layout. Am I doing something wrong?
Adding code to it. The code specific to this issue starts with till the end of coding
I declared linear layout as view and NOT VIEWGROUP.
EDIT: After doing analysis, I found that the view I am trying to slide up after sliding down the layout is hidden somewhere in the view hierarchy.
view.bringToFront() helps to bring the error view to the front and slides up.
But after that the problem is, after my linear layout slide down, the error view is not sliding up straight away. Because I am using bringToFront(), it displays the view first on the whole screen (with background color as orange) and then the sliding starts.
I am not sure whether it is correct but I fixed this issue like this.
no background color has been given to the view
I used errorView.bringToFront () and errorView.setVisibility(true) in the animationEnd() of a Layout slidingdown animation listener.
I defined sliding up animation for the errorView in the same animationEnd() of layout sliding down listener
In the animationStart() of errorView sliding up animation listener, I defined the background color of the errorView. Now its working as expected.
But let me know better way of doing this.

The java logic is in https://stackoverflow.com/questions/30523599/sliding-up-and-down-android
Please direct for any incorrect codings

I kept the view invisible and when required I made it visible and wrote the code to slide up.
I think you must do it in DialogFragment or custom AlertDialog that will be shown above your layout, if dont want to do this try envelop your RelativeLayout in FrameLayout and adding in it LinearLayout for example but visout your code difficult to say in what problem it is

You should consider using a library for the sliding panel, one that I've had excellent experiences with (and supports the functionality that your after) is umano's AndroidSlidingUpPanel. https://github.com/umano/AndroidSlidingUpPanel

Android - Layout Top Bar is pushed when key keyboard is shown

I have a simple layout with:
top bar (like action bar) with save and back button
and below a scroll view with some EditText inside... (check the image below),
When I call keyboard, my view is push above... I would like my Top Bar to stay always visible and fixed on the top... (check below the image of what is happening and what I would like to happen)
I tried several solutions with android:windowSoftInputMode, putting the top bar as relative layout and set isScrollContainer in scrollview but none have worked for me...

android:screenOrientation="portrait">
</activity>
EDIT:
I recently find out, that when you put the activity as Full Screen:
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
, the windows starts to act different from usual:
https://code.google.com/p/android/issues/detail?id=5497&q=fullscreen&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars
and as described by Dianne Hackborn in here, this is how it's working, and it seems that there is no interest in changing it.
So, I tried the Joseph Johnson's AndroidBug5497Workaround, but I always end up with a "extra" blank bar above my keyboard, and the View steel doesn't show as I want it to...
Does anyone have a nice/simple solution to this problem?

android:windowSoftInputMode="adjustResize" in the manifest for your activity will keep the top bar in view and resize the scrollview to use what room is left.
The only issue I can see with this would be lining up the edit text with the viewable area after it has been resized (if this is needed)

Add this to the activity tag in the manifest:
android:windowSoftInputMode="adjustPan"
Or programmatically:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

How to move up my controls when they would be hidden by the soft keyboard?

OK, so I have this very basic layout:
As you can see, the edit texts and the login button are centered in the area below the icon. They are not aligned with the bottom. And I want to keep it this way.
Now, when the soft keyboard is shown, all I want is that the whole view is pushed upwards, so that the login button is above the soft keyboard but takes into account its lower margin.
My activity has windowSoftInputMode set to adjustPan, but it just assures that the currently focused control is visible, not all three of them:
Question: What do I need to change so that all three controls are visible as soon as the keyboard is visible?
This is my view:

Try to use ScrollView and put your main layout inside it. I think it will do the job.

Try this in Manifest file.
<activity name="ActivityName"
android:windowSoftInputMode="stateVisible|adjustResize">
...
</activity>

As you're experiencing, adjustPan, adjustResize etc will only try to ensure the currently focused input field is visible.
What you could try to do is remove the LinearLayout then position your username password and login views in such a way that the system thinks they occupy the same space by using layout_marginTop and layout_marginBottom.

Just put this in your activity tag of your menifest file:
android:configChanges="screenSize"
And Use ScrollView in your Xml file something like below:
(I have changed your layout a bit):

At least, the answers here show that I wasn't missing anything obvious.
I now solved it like that:
windowSoftInputMode set to adjustResize
Complete layout inside a ScrollView
On layout change, I simply scroll down the ScrollView to the bottom:
public class LoginView : MvxActivity, ViewTreeObserver.IOnGlobalLayoutListener
{
private ScrollView _activityRootView;
public void OnGlobalLayout()
{
var focusedControl = Window.CurrentFocus;
_activityRootView.FullScroll(FocusSearchDirection.Down);
if (focusedControl != null)
focusedControl.RequestFocus();
else if (Window.CurrentFocus != null)
Window.CurrentFocus.ClearFocus();
}
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.LoginView);
_activityRootView = FindViewById<ScrollView>(Resource.Id.LoginViewRoot);
_activityRootView.ViewTreeObserver.AddOnGlobalLayoutListener(this);
}
}
(this is C# code using Xamarin.Android and MvvmCross. It is based on this answer)
This solution has one drawback: The controls are no longer centered in the area below the icon, but right now, I am OK with that:
See it in action

Used This Code :
public MainPage()
{
InitializeComponent();
App.Current.On<Android>().UseWindowSoftInputModeAdjust(WindowSoftInputModeAdjust.Resize);
}
