[英]How can I hide Keyboard when I click the space in jetpack compose?
我正在嘗試學習 android jetpack compose 中的文本字段,所以我在屏幕上有兩個文本字段,當我在第一個文本字段中輸入內容時,我想在單擊屏幕上的空格時關閉鍵盤。 我正在使用
.pointerInput(Unit) {
detectTapGestures(onTap = {
focusManager.clearFocus()
})
}
這行代碼,它可以工作,但它不適用於像 10 個文本字段這樣的多文本字段,例如,當我單擊 8.textfield 時,底部屏幕看起來是黑色的。 我不知道為什么它是黑色的? 任何想法?
@Composable
fun KeyboardSample(){
val focusManager = LocalFocusManager.current
Column(
modifier = Modifier
.fillMaxSize()
.pointerInput(Unit) {
detectTapGestures(onTap = {
focusManager.clearFocus()
})
}
.padding(start = 16.dp, end = 16.dp),
) {
var name by rememberSaveable { mutableStateOf("") }
val updateName = { _name : String ->
name = _name
}
var amount by rememberSaveable { mutableStateOf("") }
val updateAmount = { _amount : String ->
amount = _amount
}
TextFiledsToExperiment(
name = name,
updateName = updateName,
amount = amount,
updateAmount = updateAmount
)
}
}
@Composable
fun TextFiledsToExperiment(
name : String,
updateName : (String) -> Unit,
amount : String,
updateAmount : (String) -> Unit
){
val focusManager = LocalFocusManager.current
Column(
horizontalAlignment = Alignment.CenterHorizontally,
verticalArrangement = Arrangement.Center
) {
OutlinedTextField(
value = name,
onValueChange = updateName ,
label = { Text("Name") },
placeholder = { Text(text = "Name") },
singleLine = true,
keyboardOptions = KeyboardOptions.Default.copy(
capitalization = KeyboardCapitalization.Sentences,
autoCorrect = true,
keyboardType = KeyboardType.Text,
imeAction = ImeAction.Next
),
keyboardActions = KeyboardActions(onNext = {
focusManager.moveFocus(FocusDirection.Down)
}),
modifier = Modifier
.fillMaxWidth()
.padding(top = 6.dp, start = 0.dp, end = 0.dp, bottom = 6.dp),
)
OutlinedTextField(
value = amount,
onValueChange = updateAmount ,
label = { Text("Amount") },
placeholder = { Text(text = "Amount") },
singleLine = true,
keyboardOptions = KeyboardOptions.Default.copy(
capitalization = KeyboardCapitalization.Sentences,
autoCorrect = true,
keyboardType = KeyboardType.Number,
imeAction = ImeAction.Done
),
keyboardActions = KeyboardActions(onDone = {
focusManager.clearFocus()
}),
modifier = Modifier
.fillMaxWidth()
.padding(top = 6.dp, start = 0.dp, end = 0.dp, bottom = 6.dp),
)
}
}
您可以簡單地在列中創建可點擊修飾符並在其中運行隱藏功能。
val keyboardController = LocalSoftwareKeyboardController.current
Column(Modifier.clickable{keyboardController?.hide()}){
//
}
