问题描述

如何在Android的设置信用卡号码上面格式(之间的空格)?谁能帮我这个?

How to set credit card number in above format(spaces in between) in android? Can anyone help me with this?

推荐答案

如果我没看错,你想去做,因为用户每四个字符输入后的EditText提供输入一个空格应该放在后。

If i am not wrong, you want to do like, as user provides input in edittext after every four characters typed, a space should be placed after it.

如果这是你需要的东西,那么你就可以实现:

If this is the thing you need, then you can implement:

editText.addTextChangedListener(new TextWatcher(){
        public void afterTextChanged(Editable s) {
           // apply your logic for putting space after every four characters typed
        }
        public void beforeTextChanged(CharSequence s, int start, int count, int after){}
        public void onTextChanged(CharSequence s, int start, int before, int count){}
    });

编辑:

我认为你可以使用 PatternMatcher 类。按照第[developer.android.com]以下链接:
