Android Studio - Scrollview moves outside the screen on keyboard open

I want to make a chat screen which has an EditText and a Button at the bottom (wrapped in a LinearLayout), and a ScrollView for the messages at the top. The problem is that when the user taps the EditText and the keyboard opens, the ScrollView will go off screen as a result of moving up. I would like to move the Layout (with the EditBox and the Button) above the keyboard and the ScrollView to be resized to fit the screen. The problem is shown on the pictures below:
As you can see, the line that writes "Chat" (left image) has disappeared in the right image.
I use this XML code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="15sp"
android:orientation="vertical"
android:background="#ccdcf7"
tools:context="com.orionz.sockettest.ChatActivity">
<ScrollView
android:id="#+id/scroll"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="15"
android:isScrollContainer="false">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/chatBox"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="5dp"
android:text="Chat\n"
android:textColor="#000000"
android:textIsSelectable="true"
android:textSize="22dp" />
</LinearLayout>
</ScrollView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center|bottom"
android:orientation="horizontal">
<EditText
android:id="#+id/msgInput"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.8"
android:ems="10"
android:hint="Message..."
android:inputType="text" />
<Button
android:id="#+id/sendButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.2"

</LinearLayout>
</LinearLayout>
I have seen many answers such as setting the android:windowSoftInputMode but none has worked. I use Android Studio. Any help would be appreciated.

Try to replace the ScrollView with a ListView like this :
<ListView
android:id="#+id/list_view"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1">
</ListView>
store all the messages in an ArrayList, and set an adapter to the ListView you made :
ListView listView=(ListView) findViewById(R.id.list_view);
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,ArrayList);
listView.setAdapter(adapter);
Finally, add a listenner on your Button writing these lines :
EditText editText= (EditText) findViewById(R.id.msgInput);
ArrayList.add(editText.getText().toString());
adapter.notifyDataSetChanged();

Finally, I found what was wrong in my case.
The theme was full screen. In the style of the activity I had this line that caused the problem:
<item name="android:windowFullscreen">true</item>
In the java code, I gave a command to open the keyboard on the start of the activity:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
which was also part of the problem
After adding the adjustResize property to the activity in the manifest, everything worked fine:
android:windowSoftInputMode="adjustResize"

Wrap Scrollview to the whole layout.
i.e place editText and button inside Scrollview and set scrollView Height to android:layout_height="match_parent"

How to move focus out of ScrollView on Android with a remote control?

An app has the following in a layout:
<LinearLayout
android:id="#+id/linearLayoutContents"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="true"
android:minWidth="120dip"
android:focusableInTouchMode="true"
android:text="#string/set_up">
<requestFocus />
</Button>
...
</LinearLayout>
<ScrollView
android:id="#+id/scrollViewNewDevice"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1">
//Some EditText and AutoCompleteTextView controls
</ScrollView>
</LinearLayout>
You can see that the button gets focus intially. Once the focus is moved into the ScrollView, it can never get out of it with a remote control. Could anyone offer a tip on how to get the focus out of a ScrollView with a remote control?

I am using android:nextFocusUp = "#id/buttonAboveScrollView" for the top element inside the ScrollView to allow the focus to move out of the ScrollView when a remote control is used.

DialogFragment containing a ListView with EditText- focus wont popup keyboard

Im having difficulty to understand the unique behavior I found.
I have a layout with only a ListView, where its item layout is some texts & editText.
Showing such a dialog onscreen leads to an unexpected behavior - keyboard wont pop-up when giving focus to it.
I strangely find that if I add another element to the dialog's layout, the issue is solved.
Dialog layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/listView"
/>
<!-- patch. otherwise, EditText within listview wont pop keyboard. weird, right? -->
<EditText
android:layout_width="wrap_content"
android:visibility="gone"
android:layout_height="wrap_content" />
</LinearLayout>
Item layout:
..
...
....
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="number"
android:ems="5"
android:maxEms="5"
android:editable="true"
android:numeric="integer"
android:id="#+id/purchaseAmount" />
....
...
..
Can anyone give an explanation to that behavior?

Perhaps the ListView does not have focus. You can ensure this by modifying your xml slightly.
<ListView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/listView">
<requestFocus/>
</ListView>

Why the soft keyboard shows or not when an activity starts?

When comparing our design between developers, we found a strange behavior. After some analysis we went to this observation.
When the activity starts, on some cases the keyboard appears but sometimes not.
In fact, without a ScrollView, the soft keyboard does not appear by default on an EditText.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".TestActivity" >
<EditText
android:id="#+id/editText1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ems="10"
android:inputType="text" >
<requestFocus />
</EditText>
</LinearLayout>
But when we add a ScrollView, the soft keyboard shows up by default.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".TestActivity" >
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" >
<EditText
android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:inputType="text" >
<requestFocus />
</EditText>
</ScrollView>
</LinearLayout>
It only depends on the presence of the ScrollView. We can fix that with a specific declaration in the AndroidManifest, but this is the default behavior.
I and my fellow developer wonder why is this occurring ?

Here is what I understand of this problem after digging in the code of Android and building some test layouts with an EditText.
As ScrollView is defined as
public class More ...ScrollView extends FrameLayout { ... }
I tried using a FrameLayout as a container for an EditText item. As a result the software keyboard is not triggered.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:id="#+id/editText1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:inputType="text" >
<requestFocus />
</EditText>
</FrameLayout>
But as written in the question, using a ScrollView triggers the software keyboard (I simplified the xml source).
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:id="#+id/editText1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:inputType="text" >
<requestFocus />
</EditText>
</ScrollView>
So the element that allows the software keyboard to be triggered is in the ScrollView source file.
Edit: after having created my own class MyFrameLayout extending FrameLayout and playing with the code, I found that it is something in default scrollview style (R.attr.scrollViewStyle) that is responsible for the keyboard to be shown or not...
Edit2: finally the attribute android:scrollbars allows the keyboard to be automatically triggered at startup if present...

In my case android:scrollbars fixed this until I had to add:
android:windowSoftInputMode="adjustResize">
To be able to scroll when keyboard shows.
To be able to use both properties I had to add:
android:focusableInTouchMode="true"
In the child of the Scrollview
I found focusableInTouchMode answer here:
Stop EditText from gaining focus at Activity startup

This is because when and app is launched, android focuses on the first available view. In the first case it is the EditText, thats why the keyboard pops up. In the second case, the first view is the ScrollView is the first view, which doesn't require keyboard, so it is not shown.
Also, in the first case, you can remove <requestFocus />, and on some devices, the keyboard, will not pop up. Hope this helps.

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
