我有Edittext，其中我添加了TextWatcher.when我按退格键的工作，但如果我持有退格键，它不会删除所有文本
public sTextWatcher implements TextWatcher{
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence source, int start, int before, int count) {
}
}
@Override
public void afterTextChanged(Editable s) {
edittext.setText(s.toString());
}
答案
试试这个代码
editText.addTextChangedListener( new TextWatcher() {
boolean isEdiging;
@Override public void onTextChanged(CharSequence s, int start, int before, int count) { }
@Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { }
@Override public void afterTextChanged(Editable s) {
if(isEdiging) return;
isEdiging = true;
String str = s.toString().replaceAll("[^\d]", "");
double s1 = 0;
try {
s1 = Double.parseDouble(str);
}catch (NumberFormatException e){
e.printStackTrace();
}
NumberFormat nf2 = NumberFormat.getInstance(Locale.ENGLISH);
((DecimalFormat)nf2).applyPattern("###,###.###");
s.replace(0, s.length(), nf2.format(s1));
isEdiging = false;
} editText.addTextChangedListener( new TextWatcher() {
boolean isEdiging;
@Override public void onTextChanged(CharSequence s, int start, int before, int count) { }
@Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { }
@Override public void afterTextChanged(Editable s) {
if(isEdiging) return;
isEdiging = true;
String str = s.toString().replaceAll("[^\d]", "");
double s1 = 0;
try {
s1 = Double.parseDouble(str);
}catch (NumberFormatException e){
e.printStackTrace();
}
NumberFormat nf2 = NumberFormat.getInstance(Locale.ENGLISH);
((DecimalFormat)nf2).applyPattern("###,###.###");
s.replace(0, s.length(), nf2.format(s1));
isEdiging = false;
}
});
});
