如何在Jetpack Compose中使用widgets？

dependencies {
    implementation 'androidx.compose.ui:ui:1.0.0'
    implementation 'androidx.compose.material:material:1.0.0'
    implementation 'androidx.compose.ui:ui-tooling-preview:1.0.0'
}

import androidx.compose.foundation.Text
import androidx.compose.foundation.layout.Column
import androidx.compose.material.Button
import androidx.compose.runtime.Composable
import androidx.compose.ui.platform.setContent

@Composable
fun MyScreen() {
    Column {
        Text(text = "Hello, Jetpack Compose!")
        Button(onClick = { /* 处理按钮点击事件 */ }) {
            Text(text = "Click Me")
        }
    }
}

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            MyScreen()
        }
    }
}
