WindowManager.LayoutParams（2）

系列主要用于设置window的brightness(screenBrightness/buttonBrightness)。我们可以通过WindowManager.LayoutParams的screenBrightness/buttonBrightness变量直接进行设置。 其中screenBrightness表示屏幕的brightness,而buttonBrightness表示一般按键和键盘按键的brightness float BRIGHTNESS_OVERRIDE_FULL Value for screenBrightness and buttonBrightness  indicating that the screen or button backlight brightness should be set to the hightest value when this window is in front. 把brightness(screenBrightness/buttonBrightness)设置到最高值。 float BRIGHTNESS_OVERRIDE_NONE Default value for screenBrightness and buttonBrightness indicating that the brightness value is not overridden for this window and normal brightness policy should be used. 不对brightness(screenBrightness/buttonBrightness)重新进行设置，采用默认的普通值。 float BRIGHTNESS_OVERRIDE_OFF Value for screenBrightness and buttonBrightness indicating that the screen or button backlight brightness should be set to the lowest value when this window is in front. 把brightness(screenBrightness/buttonBrightness)设置到最低值。 changed系列 该系列主要用于 int copyFrom (WindowManager.LayoutParams o)函数中。 在函数中，首先将用参数中传入的WindowManager.LayoutParams的信息复制到本WindowManager.LayoutParams中，然后返回一个整数，以bite形式表示调用该函数后WindowManager.LayoutParams的哪些信息发送了变化 int ALPHA_CHANGED 用于表示成员变量alpha是否被改变 int ANIMATION_CHANGED 用于表示成员变量windowAnimations是否被改变 int DIM_AMOUNT_CHANGED 用于表示成员变量dimAmount是否被改变 int FLAGS_CHANGED 用于表示成员变量flags是否被改变 int LAYOUT_CHANGED 用于表示layout是否被改变.这里的layout是指以下变量所包含的信息： width，height,x,y, verticalMargin，verticalWeight,horizontalMargin，horizontalWeight int SCREEN_BRIGHTNESS_CHANGED 用于表示brightness是否被改变. 这里的brightness是指以下变量对应的信息：screenBrightness，buttonBrightness int SCREEN_ORIENTATION_CHANGED 用于表示成员变量screenOrientation是否被改变 int SOFT_INPUT_MODE_CHANGED 用于表示成员变量softInputMode是否被改变 int TITLE_CHANGED 用于表示成员变量title是否被改变 int TYPE_CHANGED 用于表示成员变量type是否被改变 int FORMAT_CHANGED Constant Value: 8 (0x00000008) 用于表示成员变量format是否被改变 成员变量 继承于ViewGroup.LayoutParams的成员变量 public int height Information about how tall the view wants to be. public LayoutAnimationController.AnimationParameters layoutAnimationParameters Used to animate layouts. public int width Information about how wide the view wants to be. 自身的成员变量 public static final Creator<<A style="COLOR: rgb(0,102,153); TEXT-DECORATION: none" href="http://developer.android.com/reference/android/view/WindowManager.LayoutParams.html" rel=nofollow>WindowManager.LayoutParams> CREATOR public float alpha An alpha value to apply to this entire window. public float buttonBrightness This can be used to override the standard behavior of the button and keyboard backlights. public float dimAmount When FLAG_DIM_BEHIND is set, this is the amount of dimming to apply. public int flags Various behavioral options/flags. public int format The desired bitmap format. public int gravity Placement of window within the screen as per Gravity. public float horizontalMargin The horizontal margin, as a percentage of the container's width, between the container and the widget. public float horizontalWeight Indicates how much of the extra space will be allocated horizontally to the view associated with these LayoutParams. public int memoryType This field is deprecated. this is ignored public String packageName Name of the package owning this window. public float screenBrightness This can be used to override the user's preferred brightness of the screen. public int screenOrientation Specific orientation value for a window. public int softInputMode Desired operating mode for any soft input area. public int systemUiVisibility Control the visibility of the status bar. public IBinder token Identifier for this window. public int type The general type of window. public float verticalMargin The vertical margin, as a percentage of the container's height, between the container and the widget. public float verticalWeight Indicates how much of the extra space will be allocated vertically to the view associated with these LayoutParams. public int windowAnimations A style resource defining the animations to use for this window. public int x X position for this window. public int y Y position for this window. 成员函数 ublic Methods final int copyFrom(WindowManager.LayoutParams o) String debug(String output) Returns a String representation of this set of layout parameters. int describeContents() Describe the kinds of special objects contained in this Parcelable's marshalled representation. final CharSequence getTitle() 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. final void setTitle(CharSequence title) String toString() Returns a string containing a concise, human-readable description of this object. void writeToParcel(Parcel out, int parcelableFlags) Flatten this object in to a Parcel.
