如何在EditText中添加数字分隔符 [英] How to add number separators in EditText

问题描述

我有一个Edittext，并且想要设置EditText，以便在用户输入要转换的数字时，应实时自动将一千个分隔符(，)自动添加到数字中.但是我想在"onTextChanged"中执行此操作"方法不在"afterTextChanged"方法中.我该怎么办?

I have an Edittext and want to set the EditText so that when the user is inputting the number to be converted, a thousand separator (,) should be added automaticaaly in realtime to the number .but i want do this in "onTextChanged" method not in the "afterTextChanged" method. How can I?

public class NumberTextWatcherForThousand implements TextWatcher {

EditText editText;


public NumberTextWatcherForThousand(EditText editText) {
    this.editText = editText;


}

@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {

}

@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {

}

@Override
public void afterTextChanged(Editable view) {
String s = null;
try {
    // The comma in the format specifier does the trick
    s = String.format("%,d", Long.parseLong(view.toString()));
    edittext.settext(s);
} catch (NumberFormatException e) {
}

}

推荐答案

我使用TextWatcher触发EditText中的每次更改，并使用此代码分隔货币部分，然后在每次字符更改后将其设置为EditText :

I use a TextWatcher to trig on every change in EditText, and use this code to separate currency sections and then set to EditText after every character changes:

public static String formatCurrencyDigit(long amount) {
    return String.format("%,d%s %s", amount, "", "");
}
