私は問題があります。日付がある 2 つの Edittext があります。addTextChangeListenerテキストの変更を確認するために使用しています。これはコードです：

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) {


    }
});

tvDateFrom で日付を変更すると、tvDateTo editview から日付に 1 週​​間追加されます。tvDateTo に日付を追加すると、日付から 1 週間減算されます。テキストウォッチャーが1つしかない場合、すべてが正常に機能します。例: tvDateFrom にのみ textChangeListener がある場合、すべて正常に動作しますが、2 番目に textchangelistener を追加するとエラーが発生します。
