    <p>Open GL seems to be your best bet here. I haven't had much experience with Android OpenGL, but it is going to be the most efficient way to write the app - since you are dealing with collision detection and colours. </p> <p>Android OpenGL will be the best option since it will be natively compiled by the ADK whereas HTML is going to be interpreted at runtime.</p> <p>As far as using normal bland Android layouts, I would not recommend that, since this is not a "standard" UI using the standard components. You are creating an entirely unique interface that is very graphical, and so I would recommend sticking to that. </p> <p><strong>EDIT:</strong> You will find that by using standard layouts that ALL of your user interface components will have to be customized, and you will spend a lot of time in your onDraw() methods with the collision detection. </p> <p>One problem with this is that you need to check whether the object collides with another object, making certain types of objects aware of each other, and may run the risk of circular references. Whereas if you use OpenGL, you can have one list of "Shape" types and then have a "checkCollision(Shape draggedObject)" method which iterates through the list of shapes and checks the collision using an optimized collision detection for the simplest object. </p> <p>The second problem is doing collision detection in the onDraw() method will make your app lag and seem sticky to the user while performing a drag. The more components the more problems.</p> <p><strong>EDIT 2:</strong> Here are some resources for Android OpenGL: <a href="http://developer.android.com/guide/topics/graphics/opengl.html" rel="nofollow noreferrer">http://developer.android.com/guide/topics/graphics/opengl.html</a><br/> <a href="http://www.learnopengles.com/android-lesson-one-getting-started/" rel="nofollow noreferrer">http://www.learnopengles.com/android-lesson-one-getting-started/</a><br/> <a href="https://stackoverflow.com/questions/5220105/2d-example-with-opengl">2D example with OpenGL</a><br/></p>

    1. COThe same as I answered/asked to @Coderer, how do I integrate OpenGL (or another language) to an android project? Do you have any good tutorial for it? Thank you!

    2. COI have added some tutorials - just remember the downside of using OpenGL is now you have to manage most things yourself, like dragging etc.

    3. COActually I wasn't afraid of collision detecting since I have to do it with a square, basically I only have to check if I'm dropping the circle inside the square or not, so I'll only check it in the moment of dropping the object :) The other thing that's giving me problem is that all this circles will have to be animated while they are being dragged, and if I create them dynamically with a bitmap (so they're not in the main.xml ) Now I don't know exactly how to animate them, most of the tutorials are using the view layouts and all this stuff!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
