[英]Jetpack Compose: How to center an item in LazyVerticalGrid?
[英]How to center Item inside Surface in jetpack compose
如何在 jet pack compose 的表面居中放置項目
@Composable
fun RoundedShapeWithIconCenter(
modifier: Modifier = Modifier,
parentSize : Dp,
parentBackgroundColor : Color,
childPadding : Dp,
icon : Painter,
iconSize : Dp,
iconTint : Color,
elevation : Dp = 0.dp,
isTextOrIcon : Boolean = false,
insideText : String = "",
insideTextColor : Color = colorResource(id = R.color.black),
fontSize: TextUnit = 16.sp
) {
Surface(
modifier = modifier.size(parentSize),
shape = RoundedCornerShape(50),
color = parentBackgroundColor,
elevation = elevation,
) {
if (isTextOrIcon) {
CommonText(value = insideText, fontSize = fontSize, color = insideTextColor, textAlign = TextAlign.Center)
} else {
Icon(painter = icon, contentDescription = "Back Arrow", modifier = Modifier
.size(iconSize)
.padding(childPadding), tint = iconTint)
}
}
}
在圖像中,圓形黑色形狀是表面,Go 是表面內的文本。 我想將 Go 文本置於 Surface 的中心。 如果我用圖標替換文本,它會完美居中
提前致謝
為此,我們已將可組合文本對齊到中心,並且我們不能在 Surface 內使用對齊修飾符。 所以我們將把我們的 CommonText 包裹在 Box 周圍,並對接受修飾符的 CommonText 做一點改變。
RoundedShapeWithIconCenter
....
if (isTextOrIcon) {
Box(modifier = Modifier
.fillMaxSize(1.0f) // it will fill parent box
.padding(8.dp)) { // padding will help us to give some margin between our text and parent if text greater then our parent size
CommonText(
value = insideText,
fontSize = fontSize,
color = insideTextColor,
modifier = Modifier.align(Alignment.Center) // this will help it to align it to box center
)
}
}
....
修改后的通用文本
因為我不知道 CommonText Composable 是如何創建的,所以我假設它喜歡跟隨並根據它進行更改。
@Composable
fun CommonText(modifier: Modifier = Modifier, .... ) {
Text(modifier = modifier, .... )
}
....
if (isTextOrIcon) {
Box(modifier = Modifier
.fillMaxSize(1.0f) // it will fill parent box
.padding(8.dp),// padding will help us to give some margin between our text and parent if text greater then our parent size
contentAlignment = Center) { // contentAlignment will align its content as provided Alignment in our case it's Center
CommonText(
value = insideText,
fontSize = fontSize,
color = insideTextColor
)
}
}
....
