我有一個BottomDrawer但我希望當BottomDrawer它關閉時gesturesEnabled應該是false否則如果它打開那么gesturesEnabled應該是true
這是
我知道它不是我的但相同的code
uj5u.com熱心網友回復：
val scope = rememberCoroutineScope()
val drawerState = rememberBottomDrawerState(BottomDrawerValue.Closed)
val gesturesEnabled = !drawerState.isClosed
Column {
Row(
modifier = Modifier.fillMaxWidth()
) {
Checkbox(gesturesEnabled, null)
Text(text = if (gesturesEnabled) "Gestures Enabled" else "Gestures Disabled")
}
BottomDrawer(
gesturesEnabled = gesturesEnabled,
drawerState = drawerState,
drawerContent = {
Button(
modifier = Modifier.align(Alignment.CenterHorizontally).padding(top = 16.dp),
onClick = { scope.launch { drawerState.close() } },
content = { Text("Close Drawer") }
)
LazyColumn {
items(25) {
ListItem(
text = { Text("Item $it") },
icon = {
Icon(
Icons.Default.Favorite,
contentDescription = "Localized description"
)
}
)
}
}
},
content = {
Column(
modifier = Modifier.fillMaxSize().padding(16.dp),
horizontalAlignment = Alignment.CenterHorizontally
) {
val openText = if (gesturesEnabled) "▲▲▲ Pull up ▲▲▲" else "Click the button!"
Text(text = if (drawerState.isClosed) openText else "▼▼▼ Drag down ▼▼▼")
Spacer(Modifier.height(20.dp))
Button(onClick = { scope.launch { drawerState.open() } }) {
Text("Click to open")
}
}
}
)
}
