Apps How to make my app full screen

[Kailas]

Hi everyone, I've just started learning android development and while I haven't run into any major road blocks yet, this is really bugging me.

When I run my app it only takes up part of the emulator's screen.

I've attached a screen shot of my app which currently contains 2 buttons, the second one has a width of 480px (which is the width of the emulator screen) and a height of fill_parent (which should make it take up the entire screen vertically as well).

I has to scale down and rotate the screen shot when I uploaded it but it still shows what I mean. Does anyone know why it wouldn't be full screen be default?

Can you post your layout XML file?

In general, though, you should set the items you want to take up the whole screen to a pixel width. Always use fill_parent, since that will ensure it works on all types of devices.

Here's my main layout xml file

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:minSdkVersion="7"
androidrientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:id="@+id/buttonNewGame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Game"
/>
<Button
android:id="@+id/buttonQuit"
android:layout_width="480px"
android:layout_height="fill_parent"
android:text="Quit"
/>
</LinearLayout>

The 480px width was a test to make sure that the emulator was the right resolution.

fill_parent was supposed to make the quit button take up the entire screen.

Edit - heh, it automatically put a smiley in.

I'm pretty sure when I woke up today and started coding again, my app was taking up the entire emulator screen like it should (I was testing a background image and I would have noticed if it wasn't working properly).

When I added a new activity to my AndroidManifest.xml, it went back to how it was yesterday. When I undid the change ... it stayed the same.

Here's another screen shot. It should be showing a grid of gray triangles 12 across and 20 down but it only shows 8 across and 12 down, while the background image is scaled down and stretched to fit into the small area that isn't even the same aspect ratio.

I rotated the image so that it would fit into the size requirements for this forum.
