我是新来的编写，我有一个问题，输入文本字段的磨损操作系统。问题是，我不能让软键盘的工作，因为它通常在Android上。而且，当我试图实现相同的布局在XML中-它的工作。所以，当我点击输入文本字段的键盘弹出，然后隐藏。当我再次点击-键盘弹出，并保持打开。但如果我尝试输入任何文本-什么都没有出现在输入字段（在键盘本身），虽然输入的文本是传递到输入文本字段的UI。
下面是我在模拟器上的日志，当我点击输入文本字段打开键盘：

2021-11-24 09:44:36.569 W/IInputConnectionWrapper: getTextBeforeCursor on inactive InputConnection
2021-11-24 09:44:36.571 W/IInputConnectionWrapper: getTextAfterCursor on inactive InputConnection
2021-11-24 09:44:36.649 W/RecordingIC: requestCursorUpdates is not supported

以下是我在真实的设备上得到的结果：

下面是我的“组合”：

@OptIn(ExperimentalComposeUiApi::class)
@Composable
fun ActivationScreen() {

    var key by remember { mutableStateOf("") }

    var isReady by remember {
        mutableStateOf(false)
    }

    Column(modifier = Modifier
        .padding(40.dp)
        .fillMaxSize()
    ) {
        val keyboardController = LocalSoftwareKeyboardController.current
        val focusRequester = FocusRequester()
        BasicTextField(
            value = key,
            onValueChange = {
                //isReady = it.length>11
                key = it
            },
            singleLine = true,
            keyboardOptions = KeyboardOptions.Default.copy(
                imeAction = ImeAction.Done
            ),
            keyboardActions = KeyboardActions(
                onDone = {
                    keyboardController?.hide()
                }
            ),
            modifier = Modifier
                .size(140.dp, 20.dp)
                .background(Color.White)
                .align(Alignment.CenterHorizontally)
                //.focusRequester(focusRequester)
                //.focusOrder(focusRequester)
        )

        Text(
            text = "ACTIVATION",
        )

        val status = if (isReady) "READY" else "NOT READY"
        Text(
            text = status,
        )
    }
}

You should avoid text input on Wear, but if you do really need it, the GBoard activity is the best way to activate.
See https://developer.android.com/reference/androidx/wear/input/RemoteInputIntentHelper.Companion#createActionRemoteInputIntent()

@Composable
fun TextInput() {
  val label = remember { mutableStateOf("Start")}
  val launcher =
    rememberLauncherForActivityResult(ActivityResultContracts.StartActivityForResult()) {
      it.data?.let { data ->
        val results: Bundle = RemoteInput.getResultsFromIntent(data)
        val ipAddress: CharSequence? = results.getCharSequence("ip_address")
        label.value = ipAddress as String
      }
    }
  Column() {
    Spacer(modifier = Modifier.height(20.dp))
    Chip(
      label = { Text(label.value) },
      onClick = {}
    )
    Chip(
      label = { Text("Search with specific IP") },
      onClick = {
        val intent: Intent = RemoteInputIntentHelper.createActionRemoteInputIntent();
        val remoteInputs: List<RemoteInput> = listOf(
          RemoteInput.Builder("ip_address")
            .setLabel("Manual IP Entry")
            .wearableExtender {
              setEmojisAllowed(false)
              setInputActionType(EditorInfo.IME_ACTION_DONE)
            }.build()
        )

        RemoteInputIntentHelper.putRemoteInputsExtra(intent, remoteInputs)

        launcher.launch(intent)
      }
    )
  }
}

Note: As @TiagoPeresFrança mentioned in the comments:
In order to use wearableExtender , you must be on version 1.2.0+ of the wear-input dependency. As of today, version 1.2.0-alpha02 should be used. In your app gradle file, make sure you have as dependency implementation 'androidx.wear:wear-input:1.2.0-alpha02' .

根据@ YuriSchimke的回答，这里有一个通用组件实现，它接受占位符、值和onChange作为属性。

import android.app.RemoteInput
import android.content.Intent
import android.os.Bundle
import android.view.inputmethod.EditorInfo
import androidx.activity.compose.rememberLauncherForActivityResult
import androidx.activity.result.contract.ActivityResultContracts
import androidx.compose.foundation.layout.*
import androidx.compose.runtime.Composable
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp
import androidx.wear.compose.material.Chip
import androidx.wear.compose.material.Text
import androidx.wear.input.RemoteInputIntentHelper
import androidx.wear.input.wearableExtender

@Composable
fun TextInput(
  placeholder: String,
  value: String?,
  onChange: (value: String) -> Unit,
) {
  val launcher =
    rememberLauncherForActivityResult(ActivityResultContracts.StartActivityForResult()) {
      it.data?.let { data ->
        val results: Bundle = RemoteInput.getResultsFromIntent(data)
        val newValue: CharSequence? = results.getCharSequence(placeholder)
        onChange(newValue as String)
      }
    }
  Column() {
    Chip(
      label = { Text(if (value == null || value.isEmpty()) placeholder else value) },
      onClick = {
        val intent: Intent = RemoteInputIntentHelper.createActionRemoteInputIntent();
        val remoteInputs: List<RemoteInput> = listOf(
          RemoteInput.Builder(placeholder)
            .setLabel(placeholder)
            .wearableExtender {
              setEmojisAllowed(false)
              setInputActionType(EditorInfo.IME_ACTION_DONE)
            }.build()
        )

        RemoteInputIntentHelper.putRemoteInputsExtra(intent, remoteInputs)

        launcher.launch(intent)
      }
    )
  }
}

注意：这需要androidx.磨损：磨损输入：1.2.0+
