Class WindowManager.LayoutParams

    • Field Detail

      • y

        public int y
        Y position for this window. With the default gravity it is ignored. When using Gravity.TOP or Gravity.BOTTOM it provides an offset from the given edge.

      • horizontalWeight

        public float horizontalWeight
        Indicates how much of the extra space will be allocated horizontally to the view associated with these LayoutParams. Specify 0 if the view should not be stretched. Otherwise the extra pixels will be pro-rated among all views whose weight is greater than 0.

      • verticalWeight

        public float verticalWeight
        Indicates how much of the extra space will be allocated vertically to the view associated with these LayoutParams. Specify 0 if the view should not be stretched. Otherwise the extra pixels will be pro-rated among all views whose weight is greater than 0.

      • FLAG_NOT_FOCUSABLE

        public static final int FLAG_NOT_FOCUSABLE
        Window flag: this window won't ever get key input focus, so the user can not send key or other button events to it. Those will instead go to whatever focusable window is behind it. This flag will also enable FLAG_NOT_TOUCH_MODAL whether or not that is explicitly set.

        Setting this flag also implies that the window will not need to interact with a soft input method, so it will be Z-ordered and positioned independently of any active input method (typically this means it gets Z-ordered on top of the input method, so it can use the full screen for its content and cover the input method if needed. You can use FLAG_ALT_FOCUSABLE_IM to modify this behavior.

        See Also:
        Constant Field Values

      • FLAG_LAYOUT_INSET_DECOR

        public static final int FLAG_LAYOUT_INSET_DECOR
        Window flag: a special option only for use in combination with FLAG_LAYOUT_IN_SCREEN. When requesting layout in the screen your window may appear on top of or behind screen decorations such as the status bar.

        See Also:
        Constant Field Values

      • FLAG_SHOW_WHEN_LOCKED

        public static final int FLAG_SHOW_WHEN_LOCKED
        Window flag: special flag to let windows be shown when the screen is locked. This will let application windows take precedence over key guard or any other lock screens. Can be used with FLAG_KEEP_SCREEN_ON to turn screen on and display windows directly before showing the key guard window. Can be used with FLAG_DISMISS_KEYGUARD to automatically fully dismisss non-secure keyguards. This flag only applies to the top-most full-screen window.
        See Also:
        Constant Field Values

      • FLAG_SHOW_WALLPAPER

        public static final int FLAG_SHOW_WALLPAPER
        Window flag: ask that the system wallpaper be shown behind your window. The window surface must be translucent to be able to actually see the wallpaper behind it; this flag just ensures that the wallpaper surface will be there if this window actually has translucent regions.

        See Also:
        Constant Field Values

      • FLAG_DISMISS_KEYGUARD

        public static final int FLAG_DISMISS_KEYGUARD
        Window flag: when set the window will cause the keyguard to be dismissed, only if it is not a secure lock keyguard. Because such a keyguard is not needed for security, it will never re-appear if the user navigates to another window (in contrast to FLAG_SHOW_WHEN_LOCKED, which will only temporarily hide both secure and non-secure keyguards but ensure they reappear when the user moves to another UI that doesn't hide them). If the keyguard is currently active and is secure (requires an unlock pattern) than the user will still need to confirm it before seeing this window, unless FLAG_SHOW_WHEN_LOCKED has also been set.
        See Also:
        Constant Field Values

      • FLAG_SPLIT_TOUCH

        public static final int FLAG_SPLIT_TOUCH
        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.
        See Also:
        Constant Field Values

      • FLAG_HARDWARE_ACCELERATED

        public static final int FLAG_HARDWARE_ACCELERATED

        Indicates whether this window should be hardware accelerated. Requesting hardware acceleration does not guarantee it will happen.

        This flag can be controlled programmatically only to enable hardware acceleration. To enable hardware acceleration for a given window programmatically, do the following:

         Window w = activity.getWindow(); // in Activity's onCreate() for instance
 w.setFlags(WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED,
         WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED);

        It is important to remember that this flag must be set before setting the content view of your activity or dialog.

        This flag cannot be used to disable hardware acceleration after it was enabled in your manifest using android.R.attr#hardwareAccelerated. If you need to selectively and programmatically disable hardware acceleration (for automated testing for instance), make sure it is turned off in your manifest and enable it on your activity or dialog when you need it instead, using the method described above.

        This flag is automatically set by the system if the android:hardwareAccelerated XML attribute is set to true on an activity or on the application.

      • FLAG_SLIPPERY

        public static final int FLAG_SLIPPERY
        Window flag: Enable touches to slide out of a window into neighboring windows in mid-gesture instead of being captured for the duration of the gesture. This flag changes the behavior of touch focus for this window only. Touches can slide out of the window but they cannot necessarily slide back in (unless the other window with touch focus permits it).

      • FLAG_NEEDS_MENU_KEY

        public static final int FLAG_NEEDS_MENU_KEY
        Flag for a window belonging to an activity that responds to KeyEvent.KEYCODE_MENU and therefore needs a Menu key. For devices where Menu is a physical button this flag is ignored, but on devices where the Menu key is drawn in software it may be hidden unless this flag is set. (Note that Action Bars, when available, are the preferred way to offer additional functions otherwise accessed via an options menu.)

      • FLAG_COMPATIBLE_WINDOW

        public static final int FLAG_COMPATIBLE_WINDOW
        Window flag: special flag to limit the size of the window to be original size ([320x480] x density). Used to create window for applications running under compatibility mode.

        Constant Field Values

      • FLAG_SYSTEM_ERROR

        public static final int FLAG_SYSTEM_ERROR

        Constant Field Values

      • PRIVATE_FLAG_FAKE_HARDWARE_ACCELERATED

        public static final int PRIVATE_FLAG_FAKE_HARDWARE_ACCELERATED
        If the window has requested hardware acceleration, but this is not allowed in the process it is in, then still render it as if it is hardware accelerated. This is used for the starting preview windows in the system process, which don't need to have the overhead of hardware acceleration (they are just a static rendering), but should be rendered as such to match the actual window of the app even if it is hardware accelerated. Even if the window isn't hardware accelerated, still do its rendering as if it was. Like FLAG_HARDWARE_ACCELERATED except for trusted system windows that need hardware acceleration (e.g. LockScreen), where hardware acceleration is generally disabled. This flag must be specified in addition to FLAG_HARDWARE_ACCELERATED to enable hardware acceleration for system windows.
        See Also:
        Constant Field Values

      • PRIVATE_FLAG_FORCE_HARDWARE_ACCELERATED

        public static final int PRIVATE_FLAG_FORCE_HARDWARE_ACCELERATED
        In the system process, we globally do not use hardware acceleration because there are many threads doing UI there and they conflict. If certain parts of the UI that really do want to use hardware acceleration, this flag can be set to force it. This is basically for the lock screen. Anyone else using it, you are probably wrong.

      • PRIVATE_FLAG_WANTS_OFFSET_NOTIFICATIONS

        public static final int PRIVATE_FLAG_WANTS_OFFSET_NOTIFICATIONS
        By default, wallpapers are sent new offsets when the wallpaper is scrolled. Wallpapers may elect to skip these notifications if they are not doing anything productive with them (they do not affect the wallpaper scrolling operation) by calling WallpaperService.Engine.setOffsetNotificationsEnabled(boolean).

      • PRIVATE_FLAG_SET_NEEDS_MENU_KEY

        public static final int PRIVATE_FLAG_SET_NEEDS_MENU_KEY
        This is set for a window that has explicitly specified its FLAG_NEEDS_MENU_KEY, so we know the value on this window is the appropriate one to use. If this is not set, we should look at windows behind it to determine the appropriate value.
        See Also:
        Constant Field Values

      • PRIVATE_FLAG_SHOW_FOR_ALL_USERS

        public static final int PRIVATE_FLAG_SHOW_FOR_ALL_USERS
        In a multiuser system if this flag is set and the owner is a system process then this window will appear on all user screens. This overrides the default behavior of window types that normally only appear on the owning user's screen. Refer to each window type to determine its default behavior.

        public static boolean mayUseInputMethod(int flags)
        Given a particular set of window manager flags, determine whether such a window may be a target for an input method when it has focus. In particular, this checks the FLAG_NOT_FOCUSABLE and FLAG_ALT_FOCUSABLE_IM flags and returns true if the combination of the two corresponds to a window that needs to be behind the input method so that the user can type into it.
        Parameters:
        flags - The current window manager flags.
        Returns:
        Returns true if such a window should be behind/interact with an input method, false if not.

      • toString

        public String toString()
        Description copied from class: Object
        Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression: 
           getClass().getName() + '@' + Integer.toHexString(hashCode())

        See Writing a useful toString method if you intend implementing your own toString method.
