Implementations§

Source§

impl LinearLayout_LayoutParams

Source

pub fn get_weight(&self) -> f32

指示 LinearLayout 中有多少额外空间将分配给与这些 LayoutParams 关联的视图。如果视图不应拉伸,请指定 0。否则,额外的像素将在权重大于 0 的所有视图之间按比例分配。

Source

pub fn set_weight(&self, value: f32)

Source

pub fn get_gravity(&self) -> i32

与这些 LayoutParams 关联的视图的重力。

Source

pub fn set_gravity(&self, value: i32)

与这些 LayoutParams 关联的视图的重力。

Source

pub fn new_with_weight(width: i32, height: i32, weight: f32) -> Self

创建一组具有指定宽度、高度和权重的新布局参数。 width 宽度,可以是 MATCH_PARENT、WRAP_CONTENT 或固定大小(以像素为单位) height 高度,可以是 MATCH_PARENT、WRAP_CONTENT 或固定大小(以像素为单位) weight 权重

Methods from Deref<Target = ViewGroup_LayoutParams>§

Source

pub const FILL_PARENT: i32 = -1i32

Source

pub const MATCH_PARENT: i32 = -1i32

Source

pub const WRAP_CONTENT: i32 = -2i32

Source

pub fn get_width(&self) -> i32

有关视图所需宽度的信息。可以是常量 FILL_PARENT(在 API 级别 8 中由 MATCH_PARENT 取代)或 WRAP_CONTENT 之一,也可以是确切的大小。

Source

pub fn set_width(&self, value: i32)

有关视图所需宽度的信息。可以是常量 FILL_PARENT(在 API 级别 8 中由 MATCH_PARENT 取代)或 WRAP_CONTENT 之一,也可以是确切的大小。

Source

pub fn get_height(&self) -> i32

有关视图所需高度的信息。可以是常量 FILL_PARENT(在 API 级别 8 中由 MATCH_PARENT 取代)或 WRAP_CONTENT 之一,也可以是确切的大小。

Source

pub fn set_height(&self, value: i32)

有关视图所需高度的信息。可以是常量 FILL_PARENT(在 API 级别 8 中由 MATCH_PARENT 取代)或 WRAP_CONTENT 之一,也可以是确切的大小。

Methods from Deref<Target = GlobalRef>§

Source

pub fn as_obj(&self) -> &JObject<'static>

Get the object from the global ref

This borrows the ref and prevents it from being dropped as long as the JObject sticks around.

Methods from Deref<Target = JObject<'static>>§

Source

pub fn as_raw(&self) -> *mut _jobject

Returns the raw JNI pointer.
