RelativeLayout is not Scrollable in ScrollView

Any idea why the following layout is not scrollable? I have a RelativeLayout in a ScrollView. The Views fit on the screen. however they are covered whenever the keyboard pops up. I want to make the screen scrollable when the keyboard pops up, because it covers the Login and password EditBoxes so it is har to see what someone is typing
<?xml version="1.0" encoding="utf-8"?>

On the activity or fragment class of this layout you have to call this:
getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

Include this in your Manifest:
<activity android:name="..." // your activity here
....
android:windowSoftInputMode="adjustResize|adjustPan">
/>
NOTE: Not sure if adding adjustPan will cause the problem to come up again or not.

If everything can fit on the screen, the ScrollView will not be able to scroll anywhere. If there is a component that is not fully visible then the scroll should be available to see the rest of the component. Without being able to see what the problem is it's hard to find the exact solution.

Android - Background reset after show/hide views with animation

I am showing and hiding views on a particular actions using some animation, I used LayoutTransition and it seems to work fine except one thing, while the animation is going, the background of some TextViews changes and reset to the default white background!!
Following is the code I am using to apply animation after hide/show.
mRightTransitioner = new LayoutTransition();
mRightTransitioner.setDuration(1000);
vg_rightContainer.setLayoutTransition(mRightTransitioner);
Edited: even without animation i tried, same problem, the background resets once view's position changes
Edited: here how i declared the views in the XML
<LinearLayout
android:id="#+id/ll_req_reasonwrapper"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_marginTop="10dp"
android:baselineAligned="false"

</LinearLayout>
</LinearLayout>
for instance: if i hide 'll_req_reasonwrapper', then the LinearLayout 'll_req_timewrapper' moves up, then the backgrounds of the textViews like 'ftv_req_starttime' becomes white!!
Please help.

Edited Answer:
if your are using linear layout then if the child is not being displayed, it is not going to be laid out and not going to be the part of the measurements ( as it looks like ). I recommend to use the RelativeLayout.
You can try
android:background="#null"
for your buttons. if your are using some custom class for button then add
.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
for this specific views.

Need more code. The fact that disabling the LayoutTransition does not solve your issue, means that the animation is not the issue.
How do you reinstantiate child views or populate your view. Are you removing views with setVisibility(View.GONE) and then setting them back with setVisibility(View.VISIBLE)
OR
Are you removing childAt(i) and then dynamically adding custom views
I'm sorry I couldnt add a comment since I dont have the reputation for that but I think I am able to answer your question if you post more code.

android - EditText height resize based on keyboard

I am having an activity in android where there is an editbox and 3 buttons below the editbox. Please see attachment. When this activity is launched, the default state is STATE1.(Please see image). The keyboard is visible by default. Now when I press the back button or dispose the keyboard, I wish to have the edittext resized and occupy the whole screen as shown in STATE2.
I am not sure how to accomplish this. I have the height of the edittext hardcoded to some dp based on the target device. I believe this has to be changed. Can anyone help me in how to accomplish this.
The XML of the layout file is below as well as the screencap
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FFFFFF" >
<LinearLayout

android:layout_height="fill_parent"
android:orientation="vertical" >
<EditText

android:layout_width="fill_parent"
android:layout_height="150dp"
android:background="#drawable/newback"
android:gravity="top"
android:imeOptions="actionDone"
android:inputType="textMultiLine|textFilter|textVisiblePassword|textNoSuggestions"
android:maxLength="200"
android:padding="5dp"

android:textColor="#000000"
/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"

<Button
android:id="#+id/PostMessage"
android:layout_width="0dp"

<Button

android:background="#drawable/newbutton_corner"
android:text="#string/DeleteMessage"
android:textColor="#FFFFFF"
android:textStyle="bold" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>

Change your EditText as follows:
<EditText
android:id="#+id/EditMessage"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:gravity="top"
android:imeOptions="actionDone"
android:inputType="textMultiLine|textFilter|textVisiblePassword|textNoSuggestions"
android:maxLength="200"
android:padding="5dp"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#000000"
/>
Add layout_weight = 1
In my opinion you do not need adjustPan. I will leave it upon you to decide. The behaviour will be different and you can try it out. Here is what the documentation says about adjustPan:
The activity's main window is not resized to make room for the soft
keyboard. Rather, the contents of the window are automatically panned
so that the current focus is never obscured by the keyboard and users
can always see what they are typing. This is generally less desirable
than resizing, because the user may need to close the soft keyboard to
get at and interact with obscured parts of the window.
Your buttons at the bottom may get hidden if using this. Instead use adjustResize:
Put this line in the activity inside AndroidManifest
android:windowSoftInputMode="stateVisible|adjustResize"

Try this.. in your manifest.
<activity
android:name="Activity"
android:windowSoftInputMode="adjustPan"/>
and your edittext use <requestFocus /> for from that start itself it'll focus
and android:layout_weight="1" it will automatically fill the screen.
<EditText
android:id="#+id/EditMessage"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#696969"
android:gravity="top"
android:imeOptions="actionDone"
android:inputType="textMultiLine|textFilter|textVisiblePassword|textNoSuggestions"
android:maxLength="200"
android:padding="5dp"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#000000"
>
<requestFocus />
</EditText>

Yes you can do that, its simple.
android:windowSoftInputMode="adjustResize" ,, add this attribute to you manifiest under required activity
Set width and height of your text view to match_parent
Done.

add android:windowSoftInputMode="adjustPan" and change android:layout_height="150dp" to android:layout_height="fill_parent"

Android ScrollView is not working

This is my .xml file where I have used two scrollview,in Input Edittext and onether in output TextView. What is wrong here...It is not working in android device.
Another problem is that when I turn my device it only shows the input text area. The output text area goes down.I want to see the half screen of input and half screen of output area.
How to fix it??
Thanks

Try setting layout_weight=1 and layout_height=0dp for the two scroll views instead of their
contents.

What is wrong here...It is not working in android device.
That's pretty vague. What were your expectations? What isn't working? In other words, please be a little more specific.
However, based on the layout code given, here are some recommendations:
Avoid hardcoding the size of views. You cannot make assumptions about screen size with the large variety of screen sizes, densities and devices out there. Also, even if you're able to make the layout look nice in portrait mode, it'll probably be not even close to that in landscape.
If you're going to put just a single View in a ScrollView, there's no need to wrap it in a ViewGroup container; just set the View directly, without nesting it again and added an extra layer of complexity to the view hierarchy.
There's no need to wrap a TextView or EditText with a ScrollView, as both views are scrollable by itself.
Regarding your second question: you can prevent Android from extracting all UI components when there's little layout estate left with the keyboard popped up. You'll need to set the IME_FLAG_NO_EXTRACT_UI flag on the EditText, or in xml: android:imeOptions="flagNoExtractUi".
I do like to point out that there's a reason Android has this behaviour by default. In most cases it hardly makes sense to force a tiny part of the UI to be visible, even more as whatever is being typed by the user is probably what really matters.

SoftKeyboard hiding EditText

I have a layout that uses an EditText to let users search a database and populate a ListView. The EditText is about 2/3 of the way from the top of the screen (positioned over an ImageView, and followed by some intro text.)
The problem is that the soft keyboard hides the EditText, so the user can't see what he's typing. (I disabled the auto-suggest.)
I've tried LinearLayout, RelativeLayout, paddings, and different alignments/centerings, but I still can't get it to work right. The EditText is either hidden, gets pushed off the top of the screen, or get "squished" and distorted.
Suggestions???
One possible workaround is to move the EditText to the top of the screen. However, this deviates from the graphic design that I was given.
Another possible workaround is for me to make the soft keyboard open in full screen (not sure how, though). This will still hide the EditText, but then I can re-enable the auto-suggestion so the user can see what he's typing... sort of... because he can only see the suggestions for what he's typing.
Here's my latest attempt. See "introFrame".
<?xml version="1.0" encoding="utf-8"?>

What you're looking for is the Activity's windowSoftInputMode attribute. You set this in your AndroidManifest.xml file, and give it a value such as:
adjustResize: "The activity's main window is always resized to make room for the soft keyboard on screen."
adjustPan: "The activity's main window is not resized to make room for the soft keyboard. Rather, the contents of the window are automatically panned so that the current focus is never obscured by the keyboard and users can always see what they are typing. This is generally less desirable than resizing, because the user may need to close the soft keyboard to get at and interact with obscured parts of the window."
adjustResize will probably work for you, as long as you wrap the layout in a ScrollView. It may have negative effects if you have a bitmap image in the background, as it will be resized as well, in which case you may want to use adjustPan instead.
<activity android:windowSoftInputMode="adjustResize" />
or
<activity android:windowSoftInputMode="adjustPan" />
More information is available at the above link.

What has worked for me is to drop my highest-level LinearLayout in a scrollView (the ScrollView can only have one child). This allowed the entire activity/form to scroll up and not clutter the EditText in focus.
First, I set in my activity:
<activity android:windowSoftInputMode="adjustPan" />
Then I did the ScrollView thing I'm talking about:
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- STUFF -->
</LinearLayout>
</ScrollView>

just use following in manifest...
<activity
android:windowSoftInputMode="adjustPan">

try giving the edit text a layout_weight (i.e. layout_weight=1) , this may have some other effects on your other layout items that you may have to work through, but this may help it stay visible when soft keyboard pops up
