我测试了您的方法,但是当我使用大量数字时它失败了……我创建了这个方法:
private String current = "";
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if(!s.toString().equals(current)){
[your_edittext].removeTextChangedListener(this);
String cleanString = s.toString().replaceAll("[$,.]", "");
double parsed = Double.parseDouble(cleanString);
String formatted = NumberFormat.getCurrencyInstance().format((parsed/100));
current = formatted;
[your_edittext].setText(formatted);
[your_edittext].setSelection(formatted.length());
[your_edittext].addTextChangedListener(this);
}
}

基于上述一些答案,我创建了一个MoneyTextWatcher,您可以按以下方式使用它:
priceEditText.addTextChangedListener(new MoneyTextWatcher(priceEditText));
这是课程:
public class MoneyTextWatcher implements TextWatcher {
private final WeakReference<EditText> editTextWeakReference;
public MoneyTextWatcher(EditText editText) {
editTextWeakReference = new WeakReference<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 editable) {
EditText editText = editTextWeakReference.get();
if (editText == null) return;
String s = editable.toString();
if (s.isEmpty()) return;
editText.removeTextChangedListener(this);
String cleanString = s.replaceAll("[$,.]", "");
BigDecimal parsed = new BigDecimal(cleanString).setScale(2, BigDecimal.ROUND_FLOOR).divide(new BigDecimal(100), BigDecimal.ROUND_FLOOR);
String formatted = NumberFormat.getCurrencyInstance().format(parsed);
editText.setText(formatted);
editText.setSelection(formatted.length());
editText.addTextChangedListener(this);
}
}
