Change Android layout from Relative to Linear

Question

I just started creating android apps, but i have a problem changing the layout, every time when i create new android project , it gives me RelativeLayout instead of LinearLayout, (well, basically i am following the book instruction, but it doesn't teach me how to change it) I assume there must be a default setting so that i can change the Relativelayout to LinearLayout .

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="@string/hello_world"
    tools:context=".MainActivity" />

</RelativeLayout>

Answer 1

In Latest versions of android studio i believe this will be the way to do it.

Go to res-> layout folder and Right Click on it and you get a sidebar asking for what type of file you want to create

Go to -> Edit File Templates option.

You will see this dialog opened. You see both options right there inside Other tab These options are LayoutResourceFile.xml and LayoutResourceFile_vertical.xml

Change the ${ROOT_TAG} to LinearLayout in both of these LayoutResourceFile.xml and LayoutResourceFile_vertical.xml and you will always get LinearLayout as parent for future.

Answer 2

Replace the following tags :

<RelativeLayout
    ... >

</RelativeLayout>

by those :

<LinearLayout
    ... >

</LinearLayout>

In addition, you should remove the following from your TextView attributes :

android:layout_centerHorizontal="true"
android:layout_centerVertical="true"

because they apply for the relative layout and not the linear layout.

If you are using Eclipse, just: Rigth click, change layout and select the layout of your choice.
