这甚至可能吗？我创造了这个观点鳍和我打电话从的onClick的XML布局内的视图的鳍状肢。我创建了一个视图的鳍状肢前，但由于某种原因它不工作。

解决方案

在上创建

  ViewFlipper mViewFlipper =（ViewFlipper）findViewbyId（位置）;

在你的onCreate（），或在onStart


  

确保无论你上的setContentView（R.layout.something）布局
  确实包含视图的鳍状肢


也可以尝试这对我来说。此行之前mViewFlipper.setDisplayedChild（ViewFlipperModes.MAIN.index（））;
式中：

  INT I =（ViewFlipperModes.MAIN.index（））;在这里放置一个调试点
mViewFlipper.setDisplayedChild（ⅰ）;

我也建议使用调试器，试图找出是否你的看法翻转事件被称为内部调试器。

Is this even possible? I created this view flipper and I am calling the view flipper from the onClick inside of the xml layout. I have created a view flipper before but for some reason it's not working.

解决方案

before on create

ViewFlipper mViewFlipper = (ViewFlipper)findViewbyId(location);

on your onCreate() or onStart

Ensure that whatever your layout on setcontentView(R.layout.something) does contain the view flipper

Also try this for me. before this line mViewFlipper.setDisplayedChild(ViewFlipperModes.MAIN.index()); Type in: 

int i = (ViewFlipperModes.MAIN.index()); place a debug point here
mViewFlipper.setDisplayedChild(i);

I also suggest using the debugger to try figure out if your flip views events are being called inside the debugger.
