Best practices for spacing between elements in LinearLayout

Question

I've created a simple LinearLayout with three identical elements:

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

    <TextView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Hello"/>

    <TextView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Hello"/>

    <TextView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Hello"/>
</LinearLayout>

Now I'm going to introduce 8dp space between each pair of elements.

Which solution of the ones below are considered as cleaner?

or:

or maybe some another?

Try this .

<?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:orientation="horizontal">

<TextView
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="Hello" />

<android.support.v4.widget.Space
    android:layout_width="8dp"
    android:layout_height="wrap_content" />

<TextView
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="Hello" />

<android.support.v4.widget.Space
    android:layout_width="8dp"
    android:layout_height="wrap_content" />

<TextView
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="Hello" />
</LinearLayout>

Add space to your code .

<android.support.v4.widget.Space
    android:layout_width="8dp"
    android:layout_height="wrap_content" />
