Struct View 

pub struct View { /* private fields */ }

Base View structure

Implementations

impl View

pub fn new(id: i64) -> Self

Create a new View with the given ID

pub fn id(&self) -> i64

Get the view ID

pub fn set_width(&self, activity: &mut Activity, width: i32) -> Result<()>

Set view width in dp (density-independent pixels)

Note: If you need to match dimensions from get_dimensions(), use set_width_px() instead, as get_dimensions() returns pixels.

pub fn set_width_px(&self, activity: &mut Activity, width: i32) -> Result<()>

Set view width in pixels

Use this when matching dimensions from get_dimensions() which returns pixel values, not dp values.

pub fn set_height(&self, activity: &mut Activity, height: i32) -> Result<()>

Set view height in dp (density-independent pixels)

Note: If you need to match dimensions from get_dimensions(), use set_height_px() instead, as get_dimensions() returns pixels.

pub fn set_height_px(&self, activity: &mut Activity, height: i32) -> Result<()>

Set view height in pixels

Use this when matching dimensions from get_dimensions() which returns pixel values, not dp values.

pub fn set_dimensions( &self, activity: &mut Activity, width: i32, height: i32, ) -> Result<()>

Set view width and height

pub fn set_margin(&self, activity: &mut Activity, margin: i32) -> Result<()>

Set view margin

pub fn set_width_wrap_content(&self, activity: &mut Activity) -> Result<()>

Set view width to WRAP_CONTENT

pub fn set_height_wrap_content(&self, activity: &mut Activity) -> Result<()>

Set view height to WRAP_CONTENT

pub fn set_width_match_parent(&self, activity: &mut Activity) -> Result<()>

Set view width to MATCH_PARENT

pub fn set_height_match_parent(&self, activity: &mut Activity) -> Result<()>

Set view height to MATCH_PARENT

pub fn set_linear_layout_params( &self, activity: &mut Activity, weight: i32, position: Option<i32>, ) -> Result<()>

Set LinearLayout parameters for this view

Arguments

• activity - The activity
• weight - Layout weight (higher weight = more space)
• position - Optional position index in the layout

pub fn set_grid_layout_params( &self, activity: &mut Activity, row: i32, col: i32, row_size: i32, col_size: i32, alignment_row: &str, alignment_col: &str, ) -> Result<()>

Set GridLayout parameters for this view

Arguments

• row - Row index (0-based)
• col - Column index (0-based)
• row_size - Number of rows this view spans (default 1)
• col_size - Number of columns this view spans (default 1)
• alignment_row - Vertical alignment: “top”, “bottom”, “center”, “baseline”, “fill”
• alignment_col - Horizontal alignment: “left”, “right”, “center”, “fill”

pub fn get_dimensions(&self, activity: &mut Activity) -> Result<(i32, i32)>

Get the dimensions (width, height) of this view in pixels Returns (width, height)

pub fn set_background_color( &self, activity: &mut Activity, color: i32, ) -> Result<()>

Set the background color of this view

Color format: 0xAARRGGBB (alpha, red, green, blue in hexadecimal)

Examples

// Solid red
view.set_background_color(activity, 0xFFFF0000u32 as i32)?;
 
// Semi-transparent blue
view.set_background_color(activity, 0x800000FFu32 as i32)?;
 
// White
view.set_background_color(activity, 0xFFFFFFFFu32 as i32)?;
