## XML attributes
### android:navigationBarColor
**This is deprecated.**
Draw proper background behind
`https://developer.android.com/reference/android/view/WindowInsets.Type#navigationBars()` or
`https://developer.android.com/reference/android/view/WindowInsets.Type#tappableElement()` instead.
May be a color value, in the form of "`#*rgb*`",
"`#*argb*`", "`#*rrggbb*`", or
"`#*aarrggbb*`".
The color for the navigation bar. If the color is not opaque, consider setting
`https://developer.android.com/reference/android/view/View#SYSTEM_UI_FLAG_LAYOUT_STABLE` and
`https://developer.android.com/reference/android/view/View#SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION`.
For this to take effect, the window must be drawing the system bar backgrounds with
`https://developer.android.com/reference/android/R.attr#windowDrawsSystemBarBackgrounds` and the navigation bar must not
have been requested to be translucent with
`https://developer.android.com/reference/android/R.attr#windowTranslucentNavigation`.
Corresponds to `https://developer.android.com/reference/android/view/Window#setNavigationBarColor(int)`.
If the color is transparent and the window enforces the navigation bar contrast, the
system will determine whether a scrim is necessary and draw one on behalf of the app to
ensure that the navigation bar has enough contrast with the contents of this app, and
set an appropriate effective bar background accordingly.
See: `https://developer.android.com/reference/android/R.attr#enforceNavigationBarContrast`
If the window belongs to an app targeting

"`#*argb*`", "`#*rrggbb*`", or
"`#*aarrggbb*`".
Shows a thin line of the specified color between the navigation bar and the app
content.
For this to take effect, the window must be drawing the system bar backgrounds with
`https://developer.android.com/reference/android/R.attr#windowDrawsSystemBarBackgrounds` and the navigation bar must not
have been requested to be translucent with
`https://developer.android.com/reference/android/R.attr#windowTranslucentNavigation`.

### requireViewById
Added in [API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public final T requireViewById (int id)
```
Finds a view that was identified by the `android:id` XML attribute
that was processed in `https://developer.android.com/reference/android/app/Activity#onCreate(android.os.Bundle)`, or throws an
IllegalArgumentException if the ID is invalid, or there is no matching view in the hierarchy.
**Note:** In most cases -- depending on compiler support --
the resulting view is automatically cast to the target class type. If
the target class type is unconstrained, an explicit cast may be
necessary.
| Parameters ||
|---|---|
| `id` | `int`: the ID to search for
|
| Returns ||
|---|---|
| `T` | a view with given ID. This value cannot be `null`.

public void setAllowEnterTransitionOverlap (boolean allow)
```
Controls how the transition set in
`https://developer.android.com/reference/android/view/Window#setEnterTransition(android.transition.Transition)` overlaps with the exit
transition of the calling Activity. When true, the transition will start as soon as possible.
When false, the transition will wait until the remote exiting transition completes before

**Related XML Attributes:**
- [android:windowAllowEnterTransitionOverlap](https://developer.android.com/reference/android/view/Window#attr_android:windowAllowEnterTransitionOverlap)
| Parameters ||
|---|---|
| `allow` | `boolean`: true to start the enter transition when possible or false to wait until the exiting transition completes.
|
### setAllowReturnTransitionOverlap
Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setAllowReturnTransitionOverlap (boolean allow)
```
Controls how the transition set in
`https://developer.android.com/reference/android/view/Window#setExitTransition(android.transition.Transition)` overlaps with the exit
transition of the called Activity when reentering after if finishes. When true,
the transition will start as soon as possible. When false, the transition will wait
until the called Activity's exiting transition completes before starting.
The default value is true.
**Related XML Attributes:**
- [android:windowAllowReturnTransitionOverlap](https://developer.android.com/reference/android/view/Window#attr_android:windowAllowReturnTransitionOverlap)
| Parameters ||
|---|---|
| `allow` | `boolean`: true to start the transition when possible or false to wait until the called Activity's exiting transition completes.
|
### setAttributes
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setAttributes (WindowManager.LayoutParams a)
```
Specify custom window attributes. **PLEASE NOTE:** the
layout params you give here should generally be from values previously
retrieved with `https://developer.android.com/reference/android/view/Window#getAttributes()`; you probably do not want to
blindly create and apply your own, since this will blow away any values
set by the framework that you are not interested in.
| Parameters ||
|---|---|
| `a` | `WindowManager.LayoutParams`: The new window attributes, which will completely override any current values.
|
### setBackgroundBlurRadius
Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setBackgroundBlurRadius (int blurRadius)
```
Blurs the screen behind the window within the bounds of the window.
The density of the blur is set by the blur radius. The radius defines the size
of the neighbouring area, from which pixels will be averaged to form the final
color for each pixel. The operation approximates a Gaussian blur.
A radius of 0 means no blur. The higher the radius, the denser the blur.
The window background drawable is drawn on top of the blurred region. The blur
region bounds and rounded corners will mimic those of the background drawable.
For the blur region to be visible, the window has to be translucent
(see `https://developer.android.com/reference/android/R.attr#windowIsTranslucent`) and floating
(see `https://developer.android.com/reference/android/R.attr#windowIsFloating`).
Note the difference with `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#setBlurBehindRadius(int)`,
which blurs the whole screen behind the window. Background blur blurs the screen behind
only within the bounds of the window.
Some devices might not support cross-window blur due to GPU limitations. It can also be
disabled at runtime, e.g. during battery saving mode, when multimedia tunneling is used or
when minimal post processing is requested. In such situations, no blur will be computed or
drawn, resulting in a transparent window background. To avoid this, the app might want to
change its theme to one that does not use blurs. To listen for cross-window blur
enabled/disabled events, use `https://developer.android.com/reference/android/view/WindowManager#addCrossWindowBlurEnabledListener(java.util.concurrent.Executor,%20java.util.function.Consumer)`.
| Parameters ||
|---|---|
| `blurRadius` | `int`: The blur radius to use for window background blur in pixels
|
**See also:**
- `https://developer.android.com/reference/android/R.styleable#Window_windowBackgroundBlurRadius`
- `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#setBlurBehindRadius(int)`

### setDecorFitsSystemWindows
Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
Deprecated in [API level
35](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setDecorFitsSystemWindows (boolean decorFitsSystemWindows)
```
**This method was deprecated
in API level 35.**
Make space in the container views to prevent the critical elements from getting
obscured by `https://developer.android.com/reference/android/view/WindowInsets.Type#systemBars()` or
`https://developer.android.com/reference/android/view/WindowInsets.Type#displayCutout()` instead.
Sets whether the decor view should fit root-level content views for `https://developer.android.com/reference/android/view/WindowInsets`.
If set to `true`, the framework will inspect the now deprecated
`https://developer.android.com/reference/android/view/View#SYSTEM_UI_LAYOUT_FLAGS` as well the
`https://developer.android.com/reference/android/view/WindowManager.LayoutParams#SOFT_INPUT_ADJUST_RESIZE` flag and fits content according
to these flags.
If set to `false`, the framework will not fit the content view to the insets and will
just pass through the `https://developer.android.com/reference/android/view/WindowInsets` to the content view.
If the app targets
`https://developer.android.com/reference/android/os/Build.VERSION_CODES#VANILLA_ICE_CREAM` or above,
the behavior will be like setting this to `false`, and cannot be changed.
| Parameters ||
|---|---|

### setDesiredHdrHeadroom
Added in [API level 35](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setDesiredHdrHeadroom (float desiredHeadroom)
```
Sets the desired amount of HDR headroom to be used when rendering as a ratio of
targetHdrPeakBrightnessInNits / targetSdrWhitePointInNits. Only applies when
`https://developer.android.com/reference/android/view/Window#setColorMode(int)` is `https://developer.android.com/reference/android/content/pm/ActivityInfo#COLOR_MODE_HDR`
By default the system will choose an amount of HDR headroom that is appropriate
for the underlying device capabilities \& bit-depth of the panel. However, for some types
of content this can end up being more headroom than necessary or desired. An example
would be a messaging app or gallery thumbnail view where some amount of HDR pop is desired
without overly influencing the perceived brightness of the majority SDR content. This can
also be used to animate in/out of an HDR range for smoother transitions.
Note: The actual amount of HDR headroom that will be given is subject to a variety
of factors such as ambient conditions, display capabilities, or bit-depth limitations.
See `https://developer.android.com/reference/android/view/Display#getHdrSdrRatio()` for more information as well as how to query the
current value.
Note: This does not impact SurfaceViews or SurfaceControls, as those have their own
independent desired HDR headroom and HDR capabilities.
| Parameters ||
|---|---|
| `desiredHeadroom` | `float`: The amount of HDR headroom that is desired. Must be \>= 1.0 (no HDR) and \<= 10,000.0. Passing 0.0 will reset to the default, automatically chosen value. Value is between 0.0f and 10000.0f inclusive

### setPreferMinimalPostProcessing
Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setPreferMinimalPostProcessing (boolean isPreferred)
```
If `isPreferred` is true, this method requests that the connected display does minimal
post processing when this window is visible on the screen. Otherwise, it requests that the
display switches back to standard image processing.
By default, the display does not do minimal post processing and if this is desired, this
method should not be used. It should be used with `isPreferred=true` when low
latency has a higher priority than image enhancement processing (e.g. for games or video
conferencing). The display will automatically go back into standard image processing mode
when no window requesting minimal posst processing is visible on screen anymore.
`setPreferMinimalPostProcessing(false)` can be used if
`setPreferMinimalPostProcessing(true)` was previously called for this window and
minimal post processing is no longer required.
If the Display sink is connected via HDMI, the device will begin to send infoframes with
Auto Low Latency Mode enabled and Game Content Type. This will switch the connected display
to a minimal image processing mode (if available), which reduces latency, improving the user
experience for gaming or video conferencing applications. For more information, see HDMI 2.1
specification.
If the Display sink has an internal connection or uses some other protocol than HDMI,
effects may be similar but implementation-defined.
The ability to switch to a mode with minimal post proessing may be disabled by a user
setting in the system settings menu. In that case, this method does nothing.
| Parameters ||
|---|---|
| `isPreferred` | `boolean`: Indicates whether minimal post processing is preferred for this window (`isPreferred=true`) or not (`isPreferred=false`).
|

Draw proper background behind `https://developer.android.com/reference/android/view/WindowInsets.Type#statusBars()`} instead.
Sets whether the system should ensure that the status bar has enough
contrast when a fully transparent background is requested.
If set to this value, the system will determine whether a scrim is necessary
to ensure that the status bar has enough contrast with the contents of
this app, and set an appropriate effective bar background color accordingly.
When the status bar color has a non-zero alpha value, the value of this
property has no effect.
| Parameters ||
|---|---|
| `ensureContrast` | `boolean`
|

### setSustainedPerformanceMode
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

Sets the Sustained Performance requirement for the calling window.
| Parameters ||
|---|---|
| `enable` | `boolean`: disables or enables the mode.
|
### setSystemGestureExclusionRects
Added in [API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setSystemGestureExclusionRects (List rects)
```
Sets a list of areas within this window's coordinate space where the system should not
intercept touch or other pointing device gestures.
This method should be used by apps that make use of
`https://developer.android.com/reference/android/view/Window#takeSurface(android.view.SurfaceHolder.Callback2)` and do not have a view hierarchy available.
Apps that do have a view hierarchy should use
`https://developer.android.com/reference/android/view/View#setSystemGestureExclusionRects(java.util.List)` instead. This method does not modify or
replace the gesture exclusion rects populated by individual views in this window's view
hierarchy using `https://developer.android.com/reference/android/view/View#setSystemGestureExclusionRects(java.util.List)`.
Use this to tell the system which specific sub-areas of a view need to receive gesture
input in order to function correctly in the presence of global system gestures that may
conflict. For example, if the system wishes to capture swipe-in-from-screen-edge gestures
to provide system-level navigation functionality, a view such as a navigation drawer
container can mark the left (or starting) edge of itself as requiring gesture capture
priority using this API. The system may then choose to relax its own gesture recognition
to allow the app to consume the user's gesture. It is not necessary for an app to register
exclusion rects for broadly spanning regions such as the entirety of a
`ScrollView` or for simple press and release click targets such as
`Button`. Mark an exclusion rect when interacting with a view requires
a precision touch gesture in a small area in either the X or Y dimension, such as
an edge swipe or dragging a `SeekBar` thumb.
Do not modify the provided list after this method is called.
| Parameters ||
|---|---|
| `rects` | `List`: A list of precision gesture regions that this window needs to function correctly. This value cannot be `null`.
|
