Put buttons with Equal margins on both left and right side in Android

I am new to Android. I want to put 4 buttons horizontally with equal margins with both left and right side as shown in the wire-frame diagram below:
I searched a lot on Google and Stackoverflow also. I tried to set android:layout_weight="1" . But it only sets equal margin from left-side. I want to set it on both sides and on multiple screen layouts. I want to know which layout and properties should be applied for this. I am using in Android studio and mostly used Drag-Drop method for design.
Currently I've XML layout as follows:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/frameLayout"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginTop="10dp"
android:id="#+id/relativeLayout">
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="3"
android:id="#+id/b3"
android:layout_gravity="left|center_vertical"
android:onClick="buttonThree"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="false"
android:layout_alignParentStart="true"
android:layout_alignParentRight="false"
android:layout_weight="1"
android:width="0dp" />
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="5"
android:id="#+id/b5"
android:layout_gravity="left|center_vertical"
android:onClick="buttonFive"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/b3"
android:layout_toEndOf="#+id/b3"
android:layout_alignParentRight="false"
android:layout_alignParentLeft="false"
android:layout_weight="1"
android:width="0dp"
android:layout_alignParentBottom="false" />
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="7"
android:id="#+id/b7"
android:layout_gravity="left|center_vertical"
android:onClick="buttonSeven"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/b5"
android:layout_toEndOf="#+id/b5"
android:layout_alignParentRight="false"
android:layout_weight="1"
android:width="0dp" />
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="9"
android:id="#+id/b9"
android:layout_gravity="left|center_vertical"
android:onClick="buttonNine"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/b7"
android:layout_toEndOf="#+id/b7"
android:layout_alignParentRight="false"
android:layout_weight="1"
android:width="0dp" />
</RelativeLayout>

Layout weight works with LinearLayout, each view in linearlayout will take designeatedweight/weightsum times total width or height.
Move your buttons into linear layout with weight sum to 4. Assigning weight of buttons to 1 will make them take 1/4 th of screen space automatically.
For equal spacing allocating margin to linear layout will make them look equally spaced.
<Button
android:id="#+id/b3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1"
android:onClick="buttonThree"
android:text="3" />
<Button
android:id="#+id/b5"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1"
android:onClick="buttonFive"
android:text="5" />
<Button
android:id="#+id/b7"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1"
android:onClick="buttonSeven"
android:text="7" />
<Button
android:id="#+id/b9"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1"
android:onClick="buttonNine"
android:text="9" />
</LinearLayout>
Result

that's right to set android:layout_weight="1" ,but only Linearlylayout effective,so you can
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:layout_weight="1"
android:layout_width="0dp"
android:layout_marginLeft="3dp"
android:layout_marginRight="3dp"
android:layout_height="wrap_content" />
<Button
android:layout_weight="1"
android:layout_width="0dp"
android:layout_marginLeft="3dp"
android:layout_marginRight="3dp"
android:layout_height="wrap_content" />
<Button
android:layout_weight="1"
android:layout_width="0dp"
android:layout_marginLeft="3dp"
android:layout_marginRight="3dp"
android:layout_height="wrap_content" />
<Button
android:layout_weight="1"
android:layout_width="0dp"
android:layout_marginLeft="3dp"
android:layout_marginRight="3dp"
android:layout_height="wrap_content" />
</LinearLayout>

Try to use LinearLayout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="3dp"
android:layout_marginBottom="3dp"
android:layout_marginLeft="3dp"
android:layout_marginRight="3dp"
android:orientation="horizontal">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginRight="3dp"
android:layout_marginLeft="3dp"
android:text="B1"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginRight="3dp"
android:text="B2"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginRight="3dp"
android:text="B3"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginRight="3dp"
android:text="B4"/>
</LinearLayout>

try out this.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="5dp"
android:weightSum="4" >
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:layout_weight="1"
android:text="B1"
android:textColor="#fff" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:layout_weight="1"
android:text="B1"
android:textColor="#fff" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:layout_weight="1"
android:text="B1"
android:textColor="#fff" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:layout_weight="1"
android:text="B1"
android:textColor="#fff" />
</LinearLayout>
it will look something like this.

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="3"
>
<Button android:id="#+id/button1"
...
android:layout_weight="1"/>
<Button android:id="#+id/button2"
...
android:layout_weight="1"/>
<Button
android:id="#+id/button3"
...
android:layout_weight="1"/>

how to set in textview same sizes

I need to implement textview with equal sizes for 3 character, but i have got some problem if i add:
This four buttons have got diferent sizes ...but i dont know why, and how can i change
MOD

There is xml code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="1dp" >
<TextView
android:id="#+id/item_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp" >
</TextView>
<TextView
android:id="#+id/item_text_Main"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="15sp" >
</TextView>
End there is picture of my problem:

Try this way,hope this will help you to solve your problem.

Give your TextView a fix size width by changing layout_width from wrap_content to some fix dp size like 30dp
Example:
<TextView
android:id="#+id/item_text"
android:layout_width="32dp"
android:layout_height="wrap_content"
android:text="MOD"
android:textSize="12sp" >
</TextView>

look like you try to make button in table like in XML???
don`t know if this can help you, but when i try to make same precise width i use this...
here`s the explanation
create 1 linear layout with vertical orientation (so, everytime you add new item, it will placed to down)
inside it, insert linear layout with horizontal orientation... (insert as many row you want, in you case looks like you need 5 linear layout with horizontal orientation)
after that, insert you button / textview inside the linear layout (horizontal orientation), so your button / text will placed horizontaly.
if you want to change row, just insert the button / textview inside another linear layout (horizontal orientation).
after you insert all, set the linear layout (horizontal value) with this code
android:weightSum="5"
why 5? because in your case, u make 5 column.
and dont forget to set the width = fill parent.
after that set the button /textview inside the linearlayout (horizontal) with add this code
android:layout_weight="1"
and dont forget to change the width with fill parent.
with this, i can make precise width in every row. next step you can set the margin to make your button / textview looks good.
hope this can help you...

Different Layouts with same weights gets different size

In my layout I have two different LinearLayouts. The first one is this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="8"
android:gravity="center"
android:text="#string/lblPais" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="#string/lblJ" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="#string/lblG" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="#string/lblP" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="#string/lblPF" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="#string/lblPC" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="#string/lblDif" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="#string/lblPuntos" />
</LinearLayout>
And the second one is this layout:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="15" >
<TextView
android:id="#+id/lblPais1"
android:layout_width="wrap_content"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="#string/lbl0" />
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="#string/lbl0" />
<TextView

As you can see both layouts get the same value for the layout_width attribute (match_parent). Inside both layouts I have the same number of elements (8 TextView). Each TextView has the same weight except the first one, that has a weight of 8.
If both layouts are the same (only differ the label on the TextViews) why do they have different sizes?

Try this way,hope this will help you to solve your problem.

if you want all layout to be same as your weight
your orientation is vertical so change...
android:layout_height="wrap_content"
to
android:layout_height="0dp"
In all TextView

You havent given android:weightSum="15" in first linear layout.

You have to add andoid:weightSum="15" on the first parent layout and everything should fall into place.

Make your parent linear layout height as
android:layout_height="match_parent"

Evenly spaced out row of buttons required

Using 3 rows and 4 columns I have tried to evenly space out all the buttons horizontally but have failed. vertically is fine.
Below are 3 different attempts to space out the buttons, 1 for each of my 3 rows. The first row stretches the graphic (which is unwanted), the second row does not stretch but there is no spacing (spacing between the graphics is required), while the third stretches without any spacing. Please help me to evenly space these out. Other peoples solutions on this same site have not worked. Should I try using a table instead?
Visual summary= without stretching the graphic:
I want | x x x x |
and not | xxxx |

try this for your first row. Similarly can be done for all the row,
So unless you don't want the images to be stretched you need to rap them in a layout. Doing so you will manage the spacing and the drawable will look just fine. If you stretch the buttons then the drawable will also be stretched accordingly.

Here is what I did with a calculator project I was working on. Requiring buttons in rows all the same size. You will need to add padding to your buttons to suit your needs.:

this is how it shows to me

Remove the android:layout_weight="1" to avoid the button filling all the space.
You should try using a TableLayout and several TableRow to replace your LinearLayouts containing the buttons, thus creating a well formated grid

I had a similar problem, solved inserting a LinearLayout in TableRow. Have a look to the posted xml code and verify if it fits your requirements.
<TableRow
android:layout_gravity="fill_horizontal"
android:paddingTop="#dimen/table_row_padding_top" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="2"
android:gravity="center_horizontal"
android:orientation="vertical" >
<ImageButton
android:contentDescription="#string/str_phone"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#drawable/icon_phone" />
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:text="#string/str_phone"
android:textColor="#000000"
android:textSize="12sp" />
