How to keep a button in a fixed place when adding lines to the TextView above?

In Android Studio I have a ScrollView and inside a layout with TextView, ImageView, another few objects and then a button.
In my app everytime you click on the button, the TextView adds another line (up to a limit), how can I prevent the button changing its place in the layout when adding a new line? (All of the objects except for one TextView and the button are Invisble).

Gridlayout does not fill_parent evenly - Android / Java

I'm not sure exactly why this is happening but I've created a GridLayout in Android and it does not fill_parent evenly as expected. Most of the icons are smushed to the left - and are not evenly distributed.
Can anyone spot why this might be happening?

Android: Changing targetSdkVersion from 15 to 18 effects the layout view

Changing the TargetSdk version in the Android Manifest.xml file from 15 to 18 affects the height of the Linearlayout. Actually the height of the Linearlayout is getting increased with the change of TargetSdk.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/footer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingTop="3dp"
android:layout_margin="0dp"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:orientation="horizontal"
android:background="#drawable/border">
<ImageButton
android:clickable="true"
android:id="#+id/f_rewards"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="center"
android:adjustViewBounds="true"
android:layout_margin="0dp"
android:padding="10dp"
android:layout_alignParentRight="true"
android:layout_weight=".33"
android:background="#drawable/border_left_footer"
android:src="#drawable/rewards_f"
/>
<ImageButton
android:clickable="true"
android:id="#+id/f_scan"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="center"
android:adjustViewBounds="true"
android:layout_margin="0dp"
android:padding="10dp"
android:layout_alignParentRight="true"
android:layout_weight=".33"
android:background="#drawable/border_left_footer"
android:src="#drawable/scan_f"
/>
<ImageButton
android:clickable="true"
android:id="#+id/f_check_in"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="center"
android:adjustViewBounds="true"
android:layout_margin="0dp"
android:padding="10dp"
android:layout_alignParentRight="true"
android:layout_weight=".33"
android:background="#drawable/border_left_footer"
android:src="#drawable/check_in_f"
/>
</LinearLayout>

okay, ive found the solution, the solution was to remove " android:adjustViewBounds="true" from ImageButton and it works :) The new xml would be this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/footer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"

android:orientation="horizontal"
android:layout_margin="0dp"
android:layout_alignParentBottom="true"
android:background="#drawable/border">
<ImageButton
android:clickable="true"
android:id="#+id/f_rewards"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="center"
android:layout_margin="0dp"
android:padding="10dp"
android:layout_weight=".33"
android:background="#drawable/border_left_footer"
android:src="#drawable/rewards_f"
/>
<ImageButton
android:id="#+id/f_scan"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="0dp"
android:layout_weight=".33"
android:background="#drawable/border_left_footer"
android:clickable="true"
android:padding="10dp"
android:scaleType="center"
android:src="#drawable/scan_f" />
<ImageButton
android:clickable="true"
android:id="#+id/f_check_in"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="center"
android:layout_margin="0dp"

Landscape mode: why do I get different result on my computer screen and different on my phone?

This is the first time I'm making an activity xml in landscape model. Until now, what I saw on my computer screen that was what I got on my phone. Now, it's not even close! I placed some layouts, buttons and stuff, centered them like I need them, and tried on the phone and some stuff are way off the screen, some stuff are moved to the right, nothing is like I made it in my xml. So I have to move some stuff a little, then try it on my phone, without any order or rule. Why is this happening?

what i know is that the emulator doesn't work same as real devices so why don't you us your phone in debug mode to see what your code really do.
post your code may be we can see if it's not the emulator problem
EDIT:
just add android:layoutweight="1" to the 3 lyouts at the bottom
you should have better results :)

Probably different resolutions on emulator and on device, and you didn't used dpi but pixels.
Also it can be a problem when using absolute layout.
Hard to gues without the code
