Android Soft keyboard float only specific layout

I have a layout, code below
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto">
<!--some stuff here-->
<LinearLayout
android:id="#+id/layout1"
android:layout_alignParentBottom="true"
android:layout_above="#+id/layout2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="5"
/>
<ImageButton
android:layout_width="50dp"
android:layout_height="50dp"
android:scaleType="fitStart"
android:layout_marginLeft="5dp"
style="#style/Base.Widget.AppCompat.Button.Borderless"
android:src="#drawable/ic_menu_send"/>
</LinearLayout>
<LinearLayout
android:id="#+id/layout2"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<!--some stuff here-->
</LinearLayout>
</RelativeLayout>
In the above code when keyboard is show i want layout2 to stay in the bottom and layout1 to go up with keyboard. if i add android:windowSoftInputMode="adjustPan|adjustResize" both layout stay in bottom. please help

as you can say this is not work
android:windowSoftInputMode="adjustPan|adjustResize"
just change it this
android:windowSoftInputMode="stateHidden"
and one more thing in your below layout
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto">
<!--some stuff here-->
<LinearLayout
android:id="#+id/layout1"
android:layout_alignParentBottom="true"
android:layout_above="#+id/layout2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="5"
/>
<ImageButton
android:layout_width="50dp"
android:layout_height="50dp"
android:scaleType="fitStart"
android:layout_marginLeft="5dp"
style="#style/Base.Widget.AppCompat.Button.Borderless"
android:src="#drawable/ic_menu_send"/>
</LinearLayout>
<LinearLayout
android:id="#+id/layout2"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#color/colorPrimary">
<!--some stuff here-->
</LinearLayout>
</RelativeLayout>
Keep in Mind :
When you have applied this property android:layout_above="#+id/layout2" to layout1 of your LinearLayout then remove this property android:layout_alignParentBottom="true" you don't require it.
So Now that look like this
<LinearLayout
android:id="#+id/layout1"
android:layout_above="#+id/layout2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
Note : I am giving background color and specific height to
LinearLayout 2 for your Understandment.
Output :
Normal Screen
KeyBoard Open Screen.
ImProve :
see the upper Image I make Red Mark that property create the problem otherwise every thing is work fine.

Please use this, and tell me if you find any difficulties
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--some stuff here-->
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/layout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/layout2"
android:layout_alignParentBottom="true"
android:orientation="horizontal">
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="5" />
<ImageButton
style="#style/Base.Widget.AppCompat.Button.Borderless"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_marginLeft="5dp"
android:scaleType="fitStart"
android:src="#drawable/ic_menu_send" />
</LinearLayout>
</ScrollView>
<LinearLayout
android:id="#+id/layout2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal">
<!--some stuff here-->
</LinearLayout>
</RelativeLayout>

Use different themes for both the layouts.
such as:
One theme refers to adjustPan for windowSoftInputMode attribute.
and another theme refers to adjustResize for windowSoftInputMode attribute.

The fastest way is hide the layouts when soft keyboard is enable and show them again when the soft keyboard is disabled (layout2 on the xml)
Remove this Line as well
android:windowSoftInputMode="adjustPan|adjustResize"
it will work , this is just a simple way , I'm still searching for you

put this line in your manifest file.
android:windowSoftInputMode="stateHidden"

Remove the android:windowSoftInputMode="adjustPan|adjustResize"
And then Hide the layout2 programmatically when soft keyboard open. When soft keyboard close, again make the layout2 visible.
This will give user an experience exactly you want.I'm not shure there is any other way. But Keep searching. good Luck

How to make a "subLayout" fixed in Android

I'm creating an app that gets some values, you click in a button and it returns some other values and this views are distributed in 2 subLayouts of a bigger vertical LinearLayout like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="10dp">
<RelativeLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:layout_weight="0.4">
<EditText
android:layout_width="70dp"
android:layout_height="wrap_content"
android:inputType="number"
android:id="#+id/number1" />
<EditText
android:layout_width="70dp"
android:layout_height="wrap_content"
android:inputType="number"
android:id="#+id/number2"
android:layout_below="#+id/number1" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Calc!"
android:id="#+id/calcButton"
android:layout_below="#+id/number2"/>
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:layout_weight="0.6"
android:layout_alignParentBottom="true">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Answer"
android:id="#+id/Answer" />
</RelativeLayout>
</LinearLayout>
My problem is that when I click on my EditText and the keyboard appears the answer's TextView goes up with the keyboard and "overrides" my button (the entire RelativeLayout follows the keyboard), there's a way of setting the RelativeLayout fixed so that it stays where it is mean to be?
Here what is happening:
There's a way of fixing that RelativeLayout?

Try setting android:windowSoftInputMode="adjustPan" for the activity in Android Manifest file.

Scrollview does not scroll when keyboard appears

I have a few EditTexts in my RelativeLayout, and a button aligned at the bottom of it. When the keyboard pops up, I want my layout to resize (therefore, I'm using android:windowSoftInputMode="adjustResize") and also want it to be scrollable, because in smaller screens resizing it isn't enough.
The problem is I can't get it to scroll at all!
I do need the Button to stay at the bottom of the screen.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFF">
<!-- some hidden RelativeLayouts, filling the whole screen -->
<RelativeLayout
android:id="#+id/form_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="match_parent" android:layout_height="match_parent"
android:fillViewport="true" android:layout_above="#+id/ok_btn">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" android:background="#99000000" android:visibility="visible">
<View
android:id="#+id/shade"
android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_alignTop="#+id/logradouro1"
android:background="#FFF" android:layout_marginTop="-30dp"/>
<!-- some visible EditTexts and TextViews here -->
</RelativeLayout>
</ScrollView>
<Button android:id="#+id/ok_btn"
android:layout_width="match_parent"
android:layout_height="50dp" android:background="#color/verdeBotao" android:text="Cadastrar"
android:textColor="#FFF" android:layout_alignParentBottom="true"/>
</RelativeLayout>
</RelativeLayout>
Below are 2 screenshots to illustrate what is happening. Please notice that I can't scroll when the keyboard is up.
Thanks!

i am posting something similar to your ui. take a RelativeLayout for the button at the bottom. set gravity to bottom and your button view should android:layout_alignParentBottom="true"
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/m_table_menu" >
<LinearLayout
android:id="#+id/layuserdetails"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:orientation="horizontal"
android:padding="5dp" >
Yourviewss......i guess edittexts
</LinearLayout>
</ScrollView>
//scrollable Button layout
<RelativeLayout
android:id="#+id/m_table_menu"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="bottom"
android:padding="0dp" >
<LinearLayout
android:id="#+id/laysharepost"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="bottom"
android:orientation="vertical"
android:padding="5dp" >
//replace textview with buttonview..
<TextView
android:id="#+id/share_tvcommentdone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#drawable/button_selector"
android:padding="10dp"
android:text="POST"
android:textColor="#android:color/white" />
</LinearLayout>
</RelativeLayout>

Black line above keyboard

Somebody know how can avoid this black line above keyboard? It become after my keyboard shows prediction words line.
Line with help words
Line after help words
In my layer I use fragment and I need show line with EditText below. But when user ends typing, he sees black line above keyboard that is not need
Here is my code:
<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"
android:orientation="vertical"
>
<!-- TODO: Update blank fragment layout -->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:id="#+id/word_set_fragment_container"
>
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Experimental layer"
/>
</FrameLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#drawable/border"
android:paddingTop="5dp"
android:paddingBottom="3dp"
android:clickable="true"
>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="⇣"
android:layout_gravity="bottom"/>
<EditText
android:inputType="text|textCapSentences"
android:imeOptions="actionDone"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:hint="#string/hint_new_word"
android:text=""
/>
</LinearLayout>
</LinearLayout>
Sorry for my english.

In order to avoid black line in your keyboard, you should add layout_margin="0px" and android:padding="0px" to you keyboard layout xml file
<android.inputmethodservice.KeyboardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/keyboard"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="0px"
android:padding="0px"
android:layout_alignParentBottom="true"
android:keyPreviewLayout ="#layout/preview"/>

This looks like its the actual android keyboard.. Which isn't something to change.

Make a component fill all available space on screen

I want something like this:
But I don't know how to resize the TextView so it gets all the available space on screen which is not ocuppied by the EditText or the Buttons. May I do it in the code, or in the xml?
At XML I tried putting the TextView into a FrameLayout, but it makes no difference. Currently looks like:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/consola"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars = "vertical"
android:text="#string/hello"/>
</FrameLayout>
<EditText
android:id="#+id/comando"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:text="Conectar"
android:id="#+id/boton_conectar"
android:layout_width="wrap_content"
android:layout_weight="0.5"
android:layout_height="wrap_content">
</Button>
<Button
android:text="Enviar"
android:id="#+id/boton_enviar"
android:layout_width="wrap_content"
android:layout_weight="0.5"
android:layout_height="wrap_content">
</Button>
</LinearLayout>
</LinearLayout>
At the code I'm just checking if the Buttons are pushed with Listeners. One of them, when pushed, gets the text at the EditText, and appends it to the TextView. It works, and TextView gets higher, while EditText and Buttons downs one line. If I go on appending lines, finaly EditText and Buttons get out of the screen. I want to avoid this behaviour, and accomplish to get this 3 widgets sticked to the bottom of the screen.

Use the android:layout_weight=1 attribute, like the buttons on the bottom of the form. That will assign most of the space to it and anything that's left to the rest of the elements.

It's all about the weight. This should give you what you want:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView android:text="TextView"
android:id="#+id/textView1"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="0dp">
</TextView>
<EditText android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<requestFocus></requestFocus>
</EditText>
<LinearLayout android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button android:text="Button"
android:id="#+id/button1"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_width="0dp">
</Button>
<Button android:text="Button"
android:id="#+id/button2"
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="1">
</Button>
</LinearLayout>
</LinearLayout>
(Side note: When using weight, setting the corresponding height/width to 0dp sometimes gets around some weird behavior.)

Try android:fillViewport="true".
