android - EditText.getText().getLength() 包含提示时是否返回 0？

Question

我有一些代码，但它没有按预期工作。我的逻辑好像没有错，所以我认为是实现错误。我的代码:

public boolean[] party_check(){
        Date date_ET = new Date(party_dateET.getYear(), party_dateET.getMonth(), party_dateET.getDayOfMonth());///Date is deprecated,
        ///but easy to handle
        ///this is used to test the date contained in the datepicker, party_dateET. If it is before the day today, then it will not write,
        ///and a message is displayed

        boolean[] return_array = new boolean[4];
        ///EditText party_titleET;
        ///EditText party_timeET;
        ///EditText party_dateET;
        ///EditText party_venueET;
        return_array[0] = true;
        if(party_titleET.getText().length() == 0){
            return_array[1] = false;
            return_array[0] = false;
        }else{
            return_array[1] = true;
        }
        if(date_ET.before(Calendar.getInstance().getTime()) == true){
            return_array[2] = false;
            return_array[0] = false;
            ///tests that the date entered is not invalid, ie. is in the future.
            ///not test for time. I could say that if time == 00:00, then don't run, or use a listener to check if it has changed,
            ///using a boolean value. But this would not really benefit the task much, so I haven't. It would also
            ///take more coding, and more complex coding.
        }else{
            return_array[2] = true;
        }
        if(party_venueET.getText().length() == 0){
            return_array[3] = false;
            return_array[0] = false;
        }else{
            return_array[3] = true;
        }
        return return_array;
        ///return_array[0] - 1st value in array - is used as toggle as to whether the party is ready or not.
        ///return_array[1-4] are used to indicate to the user which textbox is empty/ has a problem.



    }

但是，当我返回 bool 数组时，它并没有按照我的预期执行。这用于测试用户是否已将文本值输入到 EditText 中。但是它没有按预期工作。是我的逻辑有问题，还是我执行的不对？感谢您的帮助!!

当您使用 getText() 时，不会返回提示。您可以使用 getHint()虽然。
