Layout Linear or Relative in eclipse? Also how do I link multiple screens

First, the goal with any Android application is to get the application to work flawlessly on many different screen sizes, resolutions, orientations and pixel densities. That is the beauty of Android. I recommend you always test with at least one physical device and multiple emulators. With that being said layouts were one of the hardest things for me when I first started.

Anyway, try this code as your xml. It will give you four buttons. Overall, it's a relative layout with a linear layout inside the bottom left of the relative layout. When using a linear layout, you have the ability to assign a "weight" property to it's children. Layout weight is essentially a percentage of width you want the view to take up in it's linear layout parent.

<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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true" >

        <Button
            android:id="@+id/Button01"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="1" />

        <Button
            android:id="@+id/Button02"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="2" />

        <Button
            android:id="@+id/Button03"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="3" />

        <Button
            android:id="@+id/Button04"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="4" />
    </LinearLayout>

</RelativeLayout>

Lastly, there is no easy way to "link" screens like in iOS. Though it's not difficult to do in Android at all. You hit it the nail right on the head when you said "do i need to create a Android XML Layout File for each screen in the game and then use the onClickListener to link them???". For most applications, this is the route you want to go. Ideally, each activity will get it's own xml layout file. This gives the ability for the Android platform to handle stuff like the back button so you don't have to do it yourself. Developing a game is a little different though, so you may not want to follow some of these conventions. I haven't developed any games, so maybe this is something Ben Jakuben can answer.

Thanks for the the reply. I tried the XML code and it works great. However what I am trying to achieve is the landscape layout with all four buttons centered in the middle of the screen. For example 1 on top of 2 and 3 on top of 4. I've been trying all morning to make adjustments to the code you provided, yet no luck! The buttons I have created are custom buttons.

Can you draw a picture of your desired outcome?

Sure. How do I post the image on the Forum?

Upload the picture on any service online (Google Drive, Imgur, etc) and then you can either post the link or post it like this:

![alt text](/path/to/img.jpg "Title")

So it'll show up as an image in your post.

https://drive.google.com/#query?view=2&filter=images

You need to select the image you want to share and then press the share button. Then change the access on it from "Private" to "Anyone with the Link".

Thanks! I think I've got it now.

Thanks allot for the help
