本文档详细介绍了相机应用程序中模块控制流程和关键计时参数的设置，包括配置文件config.xml中的超时时间设定，如multiToggleItems_timeout和control_timeout，以及XXXModule类中布局隐藏和消失时间的管理。此外，还描述了CameraActivity如何处理模块切换、触摸事件和自动完成计时。

1. config.xml

配置各种 timeout 时间


   <integer name="multitoggleitems_timeout">3000</integer>
   <integer name="controll_timeout">3000</integer>

2. XXXModule


   public class XXXModule
           implements CameraModule, PhotoController,CaptureController,xxx{

    private static final int LAYOUT_HIDE = 100 ;
    private static final int DISAPPEAR_TIME = 3000 ;

    public void onResumeAfterSuper() {
      mActivity.onModuleSelected(ModuleSwitcher.CAPTURE_MODULE_INDEX);
    }

    Handler {
        switch (msg.what) { 
          hideviews();
       }
    }

    public void hideLayout(){
        mHandler.removeMessages(HIDE_LAYOUT);
        mHandler.sendEmptyMessage(HIDE_LAYOUT);
    }

    public void hideLayout(boolean isTouch){
        if (isTouch) {
            mHandler.removeMessages(HIDE_LAYOUT);
        } else {
            mHandler.sendEmptyMessageDelayed(HIDE_LAYOUT, DISAPPEAR_TIME);
        }
    }

    public CaptureUI getUI(){
        return mUI;
    }

   }

3. CameraActivity

CameraActivity {

   private long time= 1000 * 60 * 2;
   private ModuleSwitcherManager mModuleSwitcherManager;

   oncreate(){
         //module controll
        mModuleSwitcherManager = new ModuleSwitcherManager();
        mModuleSwitcherManager.create(this ,mCameraRootFrame);
        mModuleSwitcherManager.setOnModuleChangeListener(this);
        mCurrentModule = mModuleSwitcherManager.getCurrentCameraModule();
   }

   @Override
   public void onModuleSelected(int moduleIndex) {
        checkIfNeedRestartCountDown(null);
   }

   //auto finish
   private Runnable finishActivityRunnable = new Runnable() {
        @Override
        public void run() {
           finish();
        }
    };

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        .....
        checkIfNeedRestartCountDown(ev);
        return result;
    }

    public void checkIfNeedRestartCountDown(MotionEvent ev){
        boolean isRecording = false;
        mMainHandler.removeCallbacks(mFinishActivityRunnable);

        if (ev == null || ev.getActionMasked() == MotionEvent.ACTION_DOWN) {

            if (mModuleSwitcherManager.getCurrentCameraModule() instanceof PhotoModule) {
                ((PhotoModule) mModuleSwitcherManager.getCurrentCameraModule()).hideLayout(true);
            }

            if (mModuleSwitcherManager.getCurrentCameraModule() instanceof CaptureModule) {
                ((CaptureModule) mModuleSwitcherManager.getCurrentCameraModule()).hideLayout(true);
            }
        }

        if (ev == null || ev.getAction() == MotionEvent.ACTION_UP) {
            if (mModuleSwitcherManager.getCurrentCameraModule() instanceof PhotoModule) {
                ((PhotoModule) mModuleSwitcherManager.getCurrentCameraModule()).hideLayout(false);
                ((PhotoModule) mModuleSwitcherManager.getCurrentCameraModule()).getPhotoUI().setTouchEvent(true);
            }

            if (mModuleSwitcherManager.isVideoModule(mModuleSwitcherManager.getCurrentModuleIndex())) {
                isRecording = true;
            }

            if(!isRecording)
                mMainHandler.postDelayed(finishActivityRunnable, time);

            if (mModuleSwitcherManager.getCurrentCameraModule() instanceof CaptureModule) {
                ((CaptureModule) mModuleSwitcherManager.getCurrentCameraModule()).hideLayout(false);
                ((CaptureModule) mModuleSwitcherManager.getCurrentCameraModule()).getUI().setTouchEvent(true);
            }
        }

    }
