Я попытался найти здесь проблему, но не могу, я новичок в программировании на Android. Я публикую весь свой проект. Я думаю, что проблема где-то в методе ToDoListAdapter или onActivityResult (). Все работает, кроме тех случаев, когда я нажимаю «Отправить», новый элемент не отображается на главном экране. Я обыскал все форумы и пробовал разные способы накачивания с помощью LayoutInflater, но не знаю, что не так:

Так в чем проблема на самом деле? Разместите немного LogCat. Здесь слишком много кода, чтобы люди могли определить, с чем у вас проблемы

Ваш логарифм показывает, что вы запускаете тест, а не приложение ?!

Я вставил logCat, в котором я пытался вручную создать новую задачу.

Этот код и упражнение взяты из курса портативных систем Coursera Android. Я считаю, что это противоречит Кодексу чести Coursera.

Лучший ответ

Изменить это

if (requestCode == 1) {

К

if (requestCode == ADD_TODO_ITEM_REQUEST) {

И вам нужно изменить адаптер getview (), согласно комментариям, которые они говорят, реализуют

Todo_item.xml

//TODO - Inflate the View for this ToDoItem
// from todo_item.xml.

if(convertView == null){
    // rest of the code
    convertView = inflater.inflate(R.layout.todo_item, null);

}

Если я сделаю это, мое приложение выйдет из строя. «К сожалению, UILabs остановился» при нажатии кнопки «Отправить».

Я не могу вставить сюда logcat, но проблема в том, что всякий раз, когда я создаю новый элемент для выполнения, он не отображается на главном экране, как должен.

Запустите приложение в обычном режиме без запуска модульного теста. Затем проверьте файл logcat.

Я сделал это, и я наклеил новый котик выше. Когда я нажимаю "Отправить", все происходит по-прежнему, и я получаю сообщение «UILabs перестал работать».
