title: Why Eclipse ADT layout is so difficult to use?
body: <p>I make an Android application. And put some buttons and a progressbar on the layout. But it is very difficult to adjust those componentss' position. They will move to some where wild when I drag them. I don't know whether other persons have met the same problem.
  And what I cannot understand is that when I finish relayouting the components, I found that button1 now has function of button2, and button2 has function of button3... Who met the same problem? And could you let me know why and your solution?</p>
