我有一个像这样的字符串资源

<string name="my_string">Fancy string with an %1$s placeholder</string>

我希望将其作为输出：“带有令人惊叹的占位符的精美字符串”。这是占位符内容以粗体显示的字符串。

我怎样才能得到想要的输出？

当文本字段获得焦点时，如何将光标设置在其随机位置？相当于editText.setSelection(position)经典的 android 视图系统。

这是我用来让编辑文本在添加到屏幕时自动接收焦点的代码。我希望能够将光标从默认位置 0 移开

val (getText, setText) = remember { mutableStateOf("hello") }
AutofocusEditText(
    text = getText,
    setText = setText
)
    
...

@Composable
private fun AutofocusEditText(
    text: String,
    setText : (String) -> Unit
) {
    val focusState = remember { mutableStateOf(FocusState.Inactive) }
    val focusRequester = FocusRequester()
    val focusModifier = Modifier.focus()
    Row(
        modifier = Modifier.focusObserver { newFocusValue -> focusState.value = newFocusValue }
    ) {
        val focusRequesterModifier =
            Modifier.focusRequester(focusRequester)

        TextField(
            value = text,
            modifier = focusModifier.then(focusRequesterModifier),
            backgroundColor = Color.Transparent, …

在Android 5.0.2上更新supportVersion到27.0.0ONLY后,应用程序崩溃了这个堆栈跟踪:

W/WindowManager: Failed looking up window
            java.lang.IllegalArgumentException: Requested window android.view.ViewRootImpl$W@f004691 does not exist

无论是在设备上还是在模拟器上.

如果我把26.0.2作为supportVersion,应用程序仍然像往常一样正常工作.

UPDATE

问题依然存在 supportVersion 27.0.1
