I want to crate an dropdown menu which opens form down to top when I click an icon on an circle fixed in the left-bottom corner.
Which Elements should I combine (no code answers necessary)
Example draft
Creating a Spinner near the bottom of an activity should force it to open upwards, given there isn't enough space to list downwards. A way of forcing using this would be to add a margin to the top of your spinner to force it down so it will list upwards.

I would like to create a picture/button that is displayed over the content of an activity and I can move it anywhere on the screen. Example of functionality: If I move it close to the left side of the screen I would like the image to move to the edge when the user drops the object.
You can either use a draggable view library like DraggableView or you can implement your own onTouch handling to handle touch events for dragging image view. Here's an article for reference.

So i have this idea to create an activity that have only buttons which split the screen as presented in the picture:
I was thinking about creating some functions for each button. those functions will be dependent on the y and x axis of the screen.
Can you guys give me a direction on how to do this in a manner of using the Button and imageButton widgets in my activity.java file?

I am a very new programmer, it is part of my degree requirements and I am having a hard time with it. I am working on basically a three part GUI and I am wondering how I would create a JTextArea that will display each item that is entered.
Start by taking a look at Creating a GUI With JFC/Swing, this will give you a basic grounding in how to use Swing.
Take a closer look at How to Use Text Areas for specific details about how to use JTextArea

Let's assume that the camera is turned into a wall and all it sees is white. Once I turn off the light on my room the camera will see black.
I would like to know how can I react to such a change, is there any kind of a listener?or other way to do that?
If you are only wanting to detect brightness as in the example you gave, you might want to look at the "Light Sensor". A lot (most) android devices have a light sensor for adjusting the brightness of the screen. Try looking here: http://developer.android.com/guide/topics/sensors/sensors_overview.html
