问题 I have a ListView activity and I want an EditText (and ultimately a button along with it) to display above it. I believe my xml is fine, but for some reason the EditText is not displaying. The ListView takes up the entire screen :( Here's what my XML looks like: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <EditText android

问题 I have two traits, one extending the other, each with an inner class, one extending the other, with the same names: trait A { class X { def x() = doSomething() } } trait B extends A { class X extends super.X { override def x() = doSomethingElse() } } class C extends B { val x = new X() // here B.X is instantiated val y = new A.X() // does not compile val z = new A.this.X() // does not compile } How do I access A.X class in the C class's body?

问题 My product's description is too long and the user needs to scroll far down the page to view the Add to Cart button.

问题 I've got a page with a container that has several videos embedded from vimeo via their new universal embed. All of the videos are each in a smaller container which has the iframe embed and a paragraph describing the video. jQuery has the smaller containers initially hidden, and dynamically selects and fades in the appropriate container depending on which thumbnail you click on.
