Trouble Dragging Android Views

I'm trying to learn Android development and using the Android SDK in Eclipse. I'm following a tutorial to build the Main.XML file on the Graphical Layout tab. It instructs me to drag several Views onto the screen surface, including: Ed开发者_C百科itText, Button, RadioGroup and RadioButton.

My issue is that these Views do not seem to drag. I place the mouse cursor over them, press the right button but the Views are not captured for dragging. There are other Views (such as Gallery) that seems to drag OK but those I'm interested in (to complete the tutorial lesson) do not drag.

Any help making this work properly would be appreciated.

Forget about dragging Android elements. The best approach is to hand code them. Eclipse helps a lot, since it can show you a preview of what you wrote.

you can try to edit the properties of the button i do believe that eclipse lets you do that

Goto Help->Check for New Updates and update

And then, You'll be able to drag n drop the View components onto your xml Graphical Layout. As @MEGA said, its advisable to hand code them. But, still as a beginner, I use Graphical Layout and the set properties using the Properties tab, which is more handy (since we donno what each property is for!)
