title: android studio LinearLayout image starting point
body: <p>I am very new to android programming and I am now trying to position a "circle ball" image file into the <code>LinearLayout</code> in the middle. So, I have tried making 7 LinearLayouts equally divided and I am trying to put an image at the bottom of the 4th <code>LinearLayout</code>. The code below shows that I have 7 <code>LinearLayouts</code>. How can I put a "circle ball" image at the bottom of the 4th LinearLayout? Also, is creating 7 <code>LinearLayouts</code> a good idea? The purpose of the ball would be to move the ball to the next <code>LinearLayout</code> when I click "next" <code>Button</code>.</p>
