Question

我在我的项目中使用下面的代码制作动态复选框，如何获取复选框ID并为其创建命令，例如：

 /*
 - parameter keyLen: keyLen
 - parameter ivLen:  ivLen
 - parameter digest: digest e.g "md5" or "sha1"
 - parameter salt:   salt
 - parameter data:   data
 - parameter count:  count

 - returns: key and IV respectively
 */
open static func evpBytesToKey(_ keyLen:Int, ivLen:Int, digest:String, salt:[UInt8], data:Data, count:Int)-> [[UInt8]] {
    let saltData = Data(bytes: UnsafePointer<UInt8>(salt), count: Int(salt.count))
    var both = [[UInt8]](repeating: [UInt8](), count: 2)
    var key = [UInt8](repeating: 0,count: keyLen)
    var key_ix = 0
    var iv = [UInt8](repeating: 0,count: ivLen)
    var iv_ix = 0

    var nkey = keyLen;
    var niv = ivLen;

    var i = 0
    var addmd = 0
    var md:Data = Data()
    var md_buf:[UInt8]

    while true {

        addmd = addmd + 1
        md.append(data)
        md.append(saltData)

        if(digest=="md5"){
            md = NSData(data:md.md5()) as Data
        }else if (digest == "sha1"){
            md = NSData(data:md.sha1()) as Data
        }

        for _ in 1...(count-1){

            if(digest=="md5"){
                md = NSData(data:md.md5()) as Data
            }else if (digest == "sha1"){
                md = NSData(data:md.sha1()) as Data
            }
        }
        md_buf = Array (UnsafeBufferPointer(start: md.bytes, count: md.count))
        //            md_buf = Array(UnsafeBufferPointer(start: md.bytes.bindMemory(to: UInt8.self, capacity: md.count), count: md.length))
        i = 0
        if (nkey > 0) {
            while(true) {
                if (nkey == 0){
                    break
                }
                if (i == md.count){
                    break
                }
                key[key_ix] = md_buf[i];
                key_ix = key_ix + 1
                nkey = nkey - 1
                i = i + 1
            }
        }
        if (niv > 0 && i != md_buf.count) {
            while(true) {
                if (niv == 0){
                    break
                }
                if (i == md_buf.count){
                    break
                }
                iv[iv_ix] = md_buf[i]
                iv_ix = iv_ix + 1
                niv = niv - 1
                i = i + 1
            }
        }
        if (nkey == 0 && niv == 0) {
            break
        }

    }
    both[0] = key
    both[1] = iv

    return both

}

提前谢谢。

if(checkbox1.ischecked()==true){
//do 
}

Answer 1

你可以这样做

cb.setId(anyPositiveInteger)

尝试此操作以获取更多详细信息How can I assign an ID to a view programmatically?

Answer 2

您应该在CheckBox

中存储对所有ArrayList的所有引用

List<CheckBox > allCheckBox = new ArrayList<CheckBox>();

当您创建任何CheckBox时，您需要将其添加到List

CheckBox cb = new CheckBox(getApplicationContext());
...
allCheckBox.add(cb);

之后，您可以通过

访问CheckBox

allCheckBox.get(position).isChecked() == true
// allCheckBox.get(position) -> with return a CheckBox
// position is the index when you add checkbox to ArrayList, for example you have create 2 CheckBox dynamic
// then CheckBox1 is allCheckBox.get(0) and CheckBox2 is allCheckBox.get(1)

如何获得动态复选框ID？
