Struct Layout

pub struct Layout {
    pub default_width: Option<String>,
    pub default_height: Option<String>,
    pub gravity: Gravity,
    pub min_height: Option<String>,
    pub min_width: Option<String>,
}

Affect how an activity behaves in multi-window mode.

With Android 7.0, the manifest element supports several attributes that affect how an activity behaves in multi-window mode:

Contained in

• <activity>

Fields

default_width: Option<String>

Default width of the activity when launched in freeform mode.

default_height: Option<String>

Default height of the activity when launched in freeform mode.

gravity: Gravity

Initial placement of the activity when launched in freeform mode. See the Gravity reference for suitable values.

min_height: Option<String>

Minimum height and minimum width for the activity in both split-screen and freeform modes. If the user moves the divider in split-screen mode to make an activity smaller than the specified minimum, the system crops the activity to the size the user requests.

For example, the following code shows how to specify an activity’s default size and location, and its minimum size, when the activity is displayed in freeform mode:

XML Example

<activity android:name=".MyActivity">
   <layout android:defaultHeight="500dp"
           android:defaultWidth="600dp"
           android:gravity="top|end"
           android:minHeight="450dp"
           android:minWidth="300dp" />
</activity>

min_width: Option<String>

Minimum height and minimum width for the activity in both split-screen and freeform modes. If the user moves the divider in split-screen mode to make an activity smaller than the specified minimum, the system crops the activity to the size the user requests.

For example, the following code shows how to specify an activity’s default size and location, and its minimum size, when the activity is displayed in freeform mode:

XML Example

<activity android:name=".MyActivity">
   <layout android:defaultHeight="500dp"
           android:defaultWidth="600dp"
           android:gravity="top|end"
           android:minHeight="450dp"
           android:minWidth="300dp" />
</activity>

Trait Implementations

impl Clone for Layout

fn clone(&self) -> Layout

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Layout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Layout

fn default() -> Layout

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Layout

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Layout

fn eq(&self, other: &Layout) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Layout

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl YaDeserialize for Layout

fn deserialize<R: Read>(reader: &mut Deserializer<R>) -> Result<Self, String>

impl YaSerialize for Layout

fn serialize<W: Write>(&self, writer: &mut Serializer<W>) -> Result<(), String>

fn serialize_attributes( &self, source_attributes: Vec<OwnedAttribute>, source_namespace: Namespace, ) -> Result<(Vec<OwnedAttribute>, Namespace), String>

impl Eq for Layout

impl StructuralPartialEq for Layout
