| int | Window flag: invert the state of with respect to how this window interacts with the current method. |

Window flag: turn on dithering when compositing this window to the screen. 開啟抖動（dithering） |
| int |
Window flag: Override {@link #FLAG_FULLSCREEN and force the screen decorations (such as status bar) to be shown. 恢復window非全屏顯示 |
| int |
Window flag: Hide all screen decorations (e.g. 讓window進行全屏顯示 |
| int |
Indicates whether this window should be hardware accelerated. 對該window進行硬體加速. 該flag必須在設定你的Activity或Dialog的Content View之前進行設定， 而且如果你在mainfest檔案中用Android:hardwareAccelerated開啟了該屬性的話，那麼你在程式中就不能再改變它。mainfest檔案中android:hardwareAccelerated屬性預設是開啟的("true")。 |
| int | Window flag: intended for windows that will often be used when the user is holding the screen against their face, it will aggressively filter the event stream to prevent unintended presses in this situation that may not be desired for a particular window, when such an event stream is detected, the application will receive a CANCEL motion event to indicate this so applications can handle this accordingly by taking no action on the event until the finger is released. |
| int |
Window flag: as long as this window is visible to the user, keep the device's screen turned on and bright. 當該window對使用者可見時，讓裝置螢幕處於高亮（bright）狀態。 |
| int |
Window flag: place the window within the entire screen, ignoring decorations around the border (a.k.a. 讓window佔滿整個手機螢幕，不留任何邊界（border） |
| int |
Window flag: allow window to extend outside of the screen. window大小不再不受手機螢幕大小限制，即window可能超出螢幕之外，這時部分內容在螢幕之外。 |
| int |
Window flag: this window won't ever get key input focus, so the user can not send key or other button events to it. 讓window不能獲得焦點，這樣使用者快就不能向該window傳送按鍵事件及按鈕事件 |
| int |
Window flag: this window can never receive touch events. 讓該window不接受觸控式螢幕事件 |
| int |
Window flag: Even when this window is focusable (its {@link #FLAG_NOT_FOCUSABLE is not set), allow any pointer events outside of the window to be sent to the windows behind it. 即使在該window在可獲得焦點情況下，仍然把該window之外的任何event傳送到該window之後的其他window. |

Window flag: when set the window will accept for touch events outside of its bounds to be sent to other windows that also support split touch. When this flag is not set, the first pointer that goes down determines the window to which all subsequent touches
go until all pointers go up. When this flag is set, each pointer (not necessarily the first) that goes down determines the window to which all subsequent touches of that pointer will go until that pointer goes up thereby enabling touches with multiple pointers
to be split across multiple windows 當該window在可以接受觸控式螢幕情況下，讓因在該window之外，而傳送到後面的window的觸控式螢幕可以支援split touch. |
| int |
Window flag: When set, if the device is asleep when the touch screen is pressed, you will receive this first touch event. 當手機處於睡眠狀態時，如果螢幕被按下，那麼該window將第一個收到到事件 |

| int |
Window flag: if you have set ,
you can set this flag to receive a single special MotionEvent with the action for touches that occur outside of your window. 如果你設定了該flag,那麼在你FLAG_NOT_TOUNCH_MODAL的情況下，即使觸控式螢幕事件傳送在該window之外，其事件被髮送到了後面的window,那麼該window仍然將以MotionEvent.ACTION_OUTSIDE形式收到該觸控式螢幕事件 |

|
int |
