查看鳍状肢不翻动

Question

这甚至有可能吗？我创建了这个视图脚本，我从xml布局的onClick中调用视图脚本。我之前创建了一个视图脚蹼，但由于某种原因，它不起作用。

     private ApplicationStateManager mAppStateMananger = ApplicationStateManager.GetInstance();

      fadeDrawables(); 
     } 


     public void gotoBeatspotMain(View v) { 
      mViewFlipper.setDisplayedChild(ViewFlipperModes.MAIN.index()); 
     } 

     public void gotoNowPlaying(View v) {

之前，您的onCreate创建

ViewFlipper mViewFlipper = (ViewFlipper)findViewbyId(location); 

（），或在onStart

确保无论您对的setContentView（R.layout.something）布局 确实包含视图鳍

也试试这个给我。在这行之前mViewFlipper.setDisplayedChild（ViewFlipperModes.MAIN.index（））; 式中：

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

我也建议使用调试器，试图找出是否您的意见翻转事件被称为内部调试器。

Answer 2

setDisplayedChild接受一个索引，而不是一个id。
