Chromatron is a laser-light-mirror reflecting and addictive game.
In this puzzle game you have to place and position some mirrors, filters, etc so that the right laser beams are reflected into the matching pinwheels.

Very easy to understand, but difficult to solve.

controls:

1:use your finger to click the mirror and then select the mirror,then you click the other squares

to move the mirror.if you click the same mirror twice,it will be unselected.

2:user the arrow key(traceball) to move the cursor onto the mirror,press the center key to

select a mirror and move it. 

3:Use the arrow button(press MENU to show it) like use key control.

If you win the level you can click 'PREV','NEXT',or press MENU to select a level.


If you really stuck on some levels, press MENU to see solutions.

Layout technique: Center a TextView with a Button left and right

While working on an application which should look similar to an iPhone application, I have to create a bar at the top where I have a back and a forward button (each on one side) and a dynamic text centered in the middle between them.
To get this done, I searched quite a lot and got it finally to work.
The surrounding layout should be the RelativeLayout with two Buttons (in my case I used ImageViews) and a TextView.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="50dip"
android:background="#666666"
android:paddingTop="3dip">
<ImageView android:id="@+id/buttonLeft"
android:layout_width="50dip"
android:layout_height="50dip"
android:layout_alignParentLeft="true"
android:paddingLeft="3dip"
android:scaleType="centerInside"
android:clickable="true"
android:src="@drawable/buttonLeft"/>
<TextView android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:textColor="#000000"
android:textSize="20dip"
android:textStyle="bold"
android:text="@string/titleText"/>
<ImageView android:id="@+id/buttonRight"
android:layout_width="50dip"
android:layout_height="50dip"
android:layout_alignParentRight="true"
android:paddingRight="3dip"
android:scaleType="centerInside"
android:clickable="true"
android:src="@drawable/buttonRight"/>
</RelativeLayout>

As you can see, there are some layout params the auto completion didn’t list at all.
The params layout_centerVertical / layout_centerHorizontal do what they are named for and layout_alignParentRight / layout_alignParentLeft are like the CSS float: left / right.

Last tipp: If you have an application with different activitys/layouts but with some repeating layout parts, like the bar at the top, try to use the Tag.

<include layout="@layout/topbar" />

Of course you have to change the “topbar” to the name of your xml-layout file (without the .xml).
