Android Compose 八：常用组件 Switch

Switch 切换按钮

 val isChecked = remember { mutableStateOf(true) }

 Switch(checked = isChecked.value,
           onCheckedChange = {
           Log.i("text_compose","onCheckedChange>>"+it)
           isChecked.value = it
       }
       )

效果
默认颜色 应该对应 主题色

1.1 thumbContent 按钮选中点中显示的组件

例如

 thumbContent = {
               Text(text = "${if (isChecked.value) "开" else "关"}", color = Color.White)
           }

1.2 enabled = false,不可用

1.3 colors: SwitchColors = SwitchDefaults.colors(), 设置一堆颜色

1.3.1 checkedThumbColor = Color.Red //设置选中时 选中按钮背景颜色

效果 开字的背景没了

checkedThumbColor = Color.Yellow

1.3.2 checkedTrackColor = Color.Black //checked = true 时生效 滑动的通道颜色

1.3.3 checkedBorderColor = Color.Blue, //checked = true 时生效 选中时边框的颜色

1.3.4 checkedIconColor = Color.Black,

 thumbContent = {
               Icon(painter = painterResource(id = R.drawable.ic_android_black_24dp), contentDescription ="" )
           },
           colors = SwitchDefaults.colors(
               checkedThumbColor = Color.Yellow,  //checked = true 时生效 设置选中时  选中按钮背景颜色
               checkedTrackColor = Color.Black,  //checked = true 时生效 滑动的通道颜色
               checkedBorderColor = Color.Blue,  //checked = true 时生效 选中时边框的颜色
               checkedIconColor = Color.Black,
           )

效果，图标变黑了

checkedIconColor = Color.Red,
