问题描述

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:
I think you can use PatternMatcher
class. Follow these links on [developer.android.com]:
