我有问题。我有两个Edittexts，我有一个日期。我正在使用addTextChangeListener检查文本中的更改。这是代码：
tvDateFrom.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
Date dateFromPicker = null;
if(listOfSBPData!=null)
try {
dateFromPicker = sdf.parse(tvDateFrom.getText().toString());
String dt = tvDateFrom.getText().toString();
SimpleDateFormat dateFormat = new SimpleDateFormat( "dd-MM-yyyy" );
Calendar cal = Calendar.getInstance();
cal.setTime( dateFormat.parse( tvDateFrom.getText().toString() ) );
cal.add( Calendar.DATE, 7 );
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH);
int day = cal.get(Calendar.DAY_OF_MONTH);
tvDateTo.setText(""+day+"-"+(month+1)+"-"+year);
addSBPSeries();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
}
});
tvDateTo.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
Date dateFromPicker = null;
if(listOfSBPData!=null)
try {
dateFromPicker = sdf.parse(tvDateTo.getText().toString());
String dt = tvDateTo.getText().toString();
SimpleDateFormat dateFormat = new SimpleDateFormat( "dd-MM-yyyy" );
Calendar cal = Calendar.getInstance();
cal.setTime( dateFormat.parse( tvDateTo.getText().toString() ) );
cal.add( Calendar.DATE, 7 );
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH);
int day = cal.get(Calendar.DAY_OF_MONTH);
tvDateFrom.setText(""+day+"-"+(month+1)+"-"+year);
addSBPSeries();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
}
});
当我在tvDateFrom中更改日期时，我从tvDateTo editview添加了一周的日期。当我向tvDateTo添加日期时，我从一周的日期减去。当我只有一个文本观察者时，一切正常。例如：当我只有tvDateFrom的textChangeListener时，一切正常，但是当我第二次添加textchangelistener时，我得到错误：
