Modify Floating Action Button Default Green Border

I have a voice to text dictation application that acts as a microphone utility for a web hosted EMR platform.
We have multiple screens on this app, and one of the screens we have reserved to display only the spoken text.
In the interest of space for the text, I've decided to implement Floating Action Button and use that as a clickable microphone that will start our voice to text engine.
My question is, has anyone else had issues with a default greenish border being placed around a drawable used as the FAB src and how did you manage to modify it or get rid of it completely?
You will see my fab at the top center of the image, with the tiny little microphone being squished by that teal border.
My apologies, not enough reputation to post images, here's a link:

NumberPicker not displaying scroll controls

I have three NumberPickers defined in my app but none of them show scroll areas above the numbers - I only see the numbers themselves, with a horizontal bar above and below each. If I click on the areas above or below each horizontal bar (where I would expect the +/- scrolling controls to be) nothing happens. My layout XML is below. Any ideas??
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

I have now discovered the problem - I did not set Min and Max values for the NumberPickers - this effectively disabled the scrolling controls

In Android 4.* the number picker is different. The layout shown in Eclipse is that of Android 2.3. The NumberPicker will still work, you can swipe up/down starting from the number shown in the middle.

ImageView in LinearLayout is displayed on wrong place

I have a layout with one row:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingRight="#dimen/total_sales_page_summary_text_distance"
android:text="test2"
android:textSize="#dimen/total_sales_page_info_font_size" />
<TextView
android:id="#+id/year_on_year"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#color/total_sales_info_text_color"
android:textSize="#dimen/total_sales_page_info_font_size" />
<ImageView
android:id="#+id/tradeGreen"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_gravity="center_vertical"
android:contentDescription=""/>
</LinearLayout>
In source code I just set different number and visibility (GONE/VISIBLE) of imageview (clicking on different buttons).
as result:
image is not visible (button1 was clicked)
2.image and some long number are vivible (button2 was clicked)
3.image and other little shorter number are visible (button3)
You can compare how it looks like. Text becomes visible but image is on the previous place. Why? Why image is not moved to left.
By the way. When screen is rotated - image becomes visible on correct place.

Try to use weight.. it will align based on screen
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:gravity="center_horizontal"
android:orientation="horizontal" xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:paddingRight="#dimen/total_sales_page_summary_text_distance"
android:text="test2"
android:textSize="#dimen/total_sales_page_info_font_size" />
<TextView
android:id="#+id/year_on_year"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:textColor="#color/total_sales_info_text_color"
android:textSize="#dimen/total_sales_page_info_font_size" />
<ImageView
android:id="#+id/tradeGreen"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:layout_marginLeft="5dp"
android:layout_gravity="center_vertical"
android:contentDescription=""/>

As Deepchand rightly said, add that Image as a drawable to the TextView directly. This will take care of the Image position and will remove an extra ImageView from the layout.
So to your TextView add this,
<TextView
android:id="#+id/year_on_year"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#color/total_sales_info_text_color"
android:drawableRight="your image" //this will add an image to its right
android:drawablePadding="5dp" // you can also add padding as per you need
android:textSize="#dimen/total_sales_page_info_font_size" />
Hope this works the way you want. :)

This will be solved by using Weight.
Here your UI is horizontally so you need to change in your xml file. Like,
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:gravity="center_horizontal"
android:orientation="horizontal" xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:paddingRight="#dimen/total_sales_page_summary_text_distance"
android:text="test2"
android:textSize="#dimen/total_sales_page_info_font_size" />
<TextView
android:id="#+id/year_on_year"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:textColor="#color/total_sales_info_text_color"
android:textSize="#dimen/total_sales_page_info_font_size" />
<ImageView
android:id="#+id/tradeGreen"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:layout_marginLeft="5dp"
android:layout_gravity="center_vertical"
android:contentDescription=""/>
</LinearLayout>

How to move ImageButtons

I am working on an application for Android in Eclipse, but I have some problems with the look of the menu. I have several buttons that people can click and play sounds with them. The problem is that I don't know how to start a new line and go on with more buttons.
I'll post two images. I think the image title will tell you everything.
1st:
2nd:
The 2nd image is made with PhotoShop.
XML:

android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="match_parent"

android:orientation="horizontal" >
<ImageButton
android:id="#+id/aatrox_imgbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/aatrox" />
<ImageButton
android:id="#+id/ahri_imgbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ahri" />
<ImageButton
android:id="#+id/akali_imgbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/akali" />
<ImageButton
android:id="#+id/alistar_imgbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/alistar" />
<ImageButton
android:id="#+id/amumu_imgbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/amumu" />
<ImageButton
android:id="#+id/anivia_imgbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/anivia" />
<ImageButton
android:id="#+id/annie_imgbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/annie" />
</LinearLayout>
</ScrollView>
<Button
android:id="#+id/back_champions"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginBottom="50dp"
android:text="#string/back" />
</LinearLayout>
I tried moving the image buttons with the mouse but no success.

you need grid view. check out sample

I need to create layout compatible for all screen sizes,created separte layout for xlarge sizes(800x1280,720x1280 etc). Here I cant upload image due to reputation,need to place one main button on center of the layout ,place 3 buttons on curvely on left and right side of middle button.please can anyone help me to create the layout compatible for all screen sizes without using dp or fixed points.

you can use android:layout_weight attribute. It will allow you to use percentages to define your buttons.
For EX:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="1.0" >
<Button
android:text="left"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".50" />
<Button
android:text="right"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".50" />
</LinearLayout>
Now you have given percentages values to buttons so they will be displayed on any size of screen to their percent value of the whole screen.
This can be done in LinearLayout for RelativeLayout check second answer on this link

As mentioned in the question you want the buttons to be placed curvely at left and right of a center button, you can have a look at the link to get some idea to how to accomplish this: https://github.com/daCapricorn/ArcMenu
This is an open source project which I referred to create a Path like menu.
