android開發EditText禁止輸入中文密碼的解決方法

fun isChinese(str: String): Boolean {
    if (str.isEmpty()) {
        return false
    }
    for (c in str.toCharArray()) {
        if (c >= 0x4E00.toChar() && c <= 0x9FA5.toChar()) return true// 有一個中文字符就返回
    }
    return false
}

val filters = binding.etNewPwd.filters
val newFilters = Array(filters.size + 1) {
    if (it < filters.size) {
        filters[it]
    } else {
        InputFilter { source, _, _, _, _, _ ->
            if (EmptyUtils.isEmpty(source?.toString()) || isChinese(source.toString())) "" else source
        }
    }
}
binding.etNewPwd.filters = newFilters
