Android layout size

Question

I am using a linear layout and I want to position my EditText in center and linear layout full width.
This is my code,

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity" android:background="#eeeeee">

    <LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:paddingTop="50px"
    android:background="#666666">

        <EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/newEvent"
        android:hint="Enter the Name of Event"
        android:layout_below="@+id/textView2"
        android:layout_alignParentStart="true" />

    </LinearLayout>
</RelativeLayout>

First to make Linear layout full width you have remove the android:paddingLeft and android:paddingRight. Then about centering the EditText in Linear layout, I would not recommend using Linear layout. You could directly place EditText in relative layout and set android:layout_centerInParent="true".

Hope this helps!
