Use for example commands like:

layout_above
layout_toRightOf
layout_alignParentTop
etc.

Answer 2

In values/dimens.xml file you can set margins.

<!-- Default screen margins, per the Android Design guidelines. -->
<dimen name="activity_horizontal_margin">0dp</dimen>
<dimen name="activity_vertical_margin">0dp</dimen>

Answer 3

You can use android:layout_weight property in LinearLayout,this will override all th padding,

    <LinearLayout
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:weightSum="3">

 <TextView
    .
    .
    .
    android:layout_weight="1" />

<TextView
    .
    .
    .
    android:layout_weight="1" />

<TextView
    .
    .
    .
    android:layout_weight="1" />
 </LinearLayout>

Answer 4

Look in your RelativeLayout parent container and instead of:

android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"

put dimension to 0dp:

android:paddingRight="0dp"
android:paddingTop="0dp"
android:paddingBottom="0dp"
