Обнаружение бездействия пользователя в DialogFragment и выходе из системы через некоторое время

Question

В моем приложении много действий и фрагментов диалога. Я искал информацию об обнаружении активности и узнал о функции onUserInterAction, но он обнаруживает активность только для действий, но не во время открытия диалогового фрагмента.

Answer 1

Я решил это, создав обертку в обратном вызове окна диалога.

YourDialogFragment.java

@Override 
public void onStart() { 
    super.onStart(); 
    UserInteractionInterceptor.wrapWindowCallback(getDialog().getWindow(), getActivity()); 
} 

UserInteractionInterceptor.java

public class UserInteractionInterceptor { 

public static void wrapWindowCallback(Window window, FragmentActivity activity) { 
    Window.Callback originalCallback = window.getCallback(); 

    window.setCallback(new Window.Callback() { 
     @Override 
     public boolean dispatchKeyEvent(KeyEvent event) { 
      return originalCallback.dispatchKeyEvent(event); 
     } 

     @Override 
     public boolean dispatchKeyShortcutEvent(KeyEvent event) { 
      return originalCallback.dispatchKeyShortcutEvent(event); 
     } 
     //This is the important override 
     @Override 
     public boolean dispatchTouchEvent(MotionEvent event) { 
      if(event.getAction() == MotionEvent.ACTION_DOWN) { 
       if(activity != null) 
        activity.onUserInteraction(); 
      } 
      return originalCallback.dispatchTouchEvent(event); 
     } 

     @Override 
     public boolean dispatchTrackballEvent(MotionEvent event) { 
      return originalCallback.dispatchTrackballEvent(event); 
     } 

     @Override 
     public boolean dispatchGenericMotionEvent(MotionEvent event) { 
      return originalCallback.dispatchGenericMotionEvent(event); 
     } 

     @Override 
     public boolean dispatchPopulateAccessibilityEvent(AccessibilityEvent event) { 
      return originalCallback.dispatchPopulateAccessibilityEvent(event); 
     } 

     @Nullable 
     @Override 
     public View onCreatePanelView(int featureId) { 
      return originalCallback.onCreatePanelView(featureId); 
     } 

     @Override 
     public boolean onCreatePanelMenu(int featureId, Menu menu) { 
      return originalCallback.onCreatePanelMenu(featureId, menu); 
     } 

     @Override 
     public boolean onPreparePanel(int featureId, View view, Menu menu) { 
      return originalCallback.onPreparePanel(featureId, view, menu); 
     } 

     @Override 
     public boolean onMenuOpened(int featureId, Menu menu) { 
      return originalCallback.onMenuOpened(featureId, menu); 
     } 

     @Override 
     public boolean onMenuItemSelected(int featureId, MenuItem item) { 
      return originalCallback.onMenuItemSelected(featureId, item); 
     } 

     @Override 
     public void onWindowAttributesChanged(WindowManager.LayoutParams attrs) { 
      originalCallback.onWindowAttributesChanged(attrs); 
     } 

     @Override 
     public void onContentChanged() { 
      originalCallback.onContentChanged(); 
     } 

     @Override 
     public void onWindowFocusChanged(boolean hasFocus) { 
      originalCallback.onWindowFocusChanged(hasFocus); 
     } 

     @Override 
     public void onAttachedToWindow() { 
      originalCallback.onAttachedToWindow(); 
     } 

     @Override 
     public void onDetachedFromWindow() { 
      originalCallback.onDetachedFromWindow(); 
     } 

     @Override 
     public void onPanelClosed(int featureId, Menu menu) { 
      originalCallback.onPanelClosed(featureId, menu); 
     } 

     @Override 
     public boolean onSearchRequested() { 
      return originalCallback.onSearchRequested(); 
     } 

     @TargetApi(Build.VERSION_CODES.M) 
     @Override 
     public boolean onSearchRequested(SearchEvent searchEvent) { 
      return originalCallback.onSearchRequested(searchEvent); 
     } 

     @Nullable 
     @Override 
     public ActionMode onWindowStartingActionMode(ActionMode.Callback callback) { 
      return originalCallback.onWindowStartingActionMode(callback); 
     } 

     @TargetApi(Build.VERSION_CODES.M) 
     @Nullable 
     @Override 
     public ActionMode onWindowStartingActionMode(ActionMode.Callback callback, int type) { 
      return originalCallback.onWindowStartingActionMode(callback, type); 
     } 

     @Override 
     public void onActionModeStarted(ActionMode mode) { 
      originalCallback.onActionModeStarted(mode); 
     } 

     @Override 
     public void onActionModeFinished(ActionMode mode) { 
      originalCallback.onActionModeFinished(mode); 
     } 
    }); 
}
