我嘗試關注 developer.android.com/jetpack/compose/text#displaying-text 并獲得
Unresolved reference: remember
Unresolved reference: mutableStateOf
Unresolved reference: OutlinedTextField
Unresolved reference: it
我究竟做錯了什么？
整體功能：
@Composable
fun SimpleOutlinedTextFieldSample() {
var text by remember { mutableStateOf("") }
OutlinedTextField(
value = text,
onValueChange = { text = it },
label = { Text("Label") }
)
}
進口：
import android.os.Bundle
import androidx.activity.ComponentActivity
import androidx.activity.compose.setContent
import androidx.compose.material.MaterialTheme
import androidx.compose.material.Surface
import androidx.compose.material.Text
import androidx.compose.runtime.Composable
import androidx.compose.ui.tooling.preview.Preview
import com.example.kotlinprojectapp.ui.theme.KotlinProjectAppTheme
uj5u.com熱心網友回復：
正確的進口：
import androidx.compose.runtime.remember
import androidx.compose.material.OutlinedTextField
import androidx.compose.runtime.mutableStateOf
