嘿，我正在努力檢測我的應用程式中的自定義鍵盤。我成功地做到了這一點，并通過使用代碼檢測用戶是自定義鍵盤
fun isUsingCustomKeyboard(context: Context): Boolean {
val imm: InputMethodManager = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
val inputMethodProperties: List<InputMethodInfo> = imm.enabledInputMethodList
for (i in 0..inputMethodProperties.size) { // loop to every input method
val inputMethodInfo = inputMethodProperties[i]
val inputMethodId = Settings.Secure.getString(
context.contentResolver,
Settings.Secure.DEFAULT_INPUT_METHOD
)
if (inputMethodInfo.id.equals(inputMethodId)) {
if (inputMethodInfo.serviceInfo.applicationInfo.flags and ApplicationInfo.FLAG_SYSTEM == 0) {
return true
}
break
}
}
return false
}
但是我收到了這個錯誤，有人能告訴我上面的代碼出了什么問題嗎

uj5u.com熱心網友回復：
for (i in 0..inputMethodProperties.size) {size 給出串列中的物件數，但索引從 0 開始，因此當您嘗試讀取最后一個超出范圍時。size -1 是最后一個索引。
