当我更改 edittext 的值时,我想添加逗号分隔值和小数点?
当任何人根据edittext逗号中的数字更改editext中的值时,我想实时执行它应该添加或删除吗?
有没有办法将逗号作为小数分隔符?
请在您的班级中实现以下所有功能。
final EditText editText1 = (EditText) findViewById(R.id.editText1);
editText1.setText("1,200.40");
editText1.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int arg1, int arg2,
int arg3) {
insertCommaIntoNumber(editText1,s);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
}
});
private void insertCommaIntoNumber(EditText etText,CharSequence s)
{
try {
if (s.toString().length() > 0)
{
String convertedStr = s.toString();
if (s.toString().contains("."))
{
if(chkConvert(s.toString()))
convertedStr = customFormat("###,###.##",Double.parseDouble(s.toString().replace(",","")));
}
else
{
convertedStr = customFormat("###,###.##", Double.parseDouble(s.toString().replace(",","")));
}
if (!etText.getText().toString().equals(convertedStr) && convertedStr.length() > 0) {
etText.setText(convertedStr);
etText.setSelection(etText.getText().length());
}
}
} catch (NullPointerException e) {
e.printStackTrace();
}
}
public String customFormat(String pattern, double value) {
DecimalFormat myFormatter = new DecimalFormat(pattern);
String output = myFormatter.format(value);
return output;
}
public boolean chkConvert(String s)
{
String tempArray[] = s.toString().split("\\.");
if (tempArray.length > 1)
{
if (Integer.parseInt(tempArray[1]) > 0) {
return true;
}
else
return false;
}
else
return false;
}
