Проблема с ошибкой редактирования текста в навигационном ящике

#android

#Android

Вопрос:

Всякий раз, когда я снова нажимаю на свой editext, он выходит из строя и отображает это сообщение об ошибке. Например: я уже ввожу что-то в editext, а затем, когда я снова нажимаю на editext, появляется сообщение о сбое.

Вот макет заголовка в панели навигации, где находится редактируемый текст.

Пожалуйста, помогите мне с этим. Спасибо

Комментарии:

1. Ваш logcat сказал: Attempt to invoke virtual method 'int android.graphics.drawable.Drawable.getIntrinsicWidth()' on a null object reference . Вам нужно проверить, почему возникает нулевая ссылка из чертежа. Возможно, вы еще не назначили на него какую-либо ссылку, прежде чем использовать его.

2. Я ничего не установил относительно getIntrinsicWidth в моей java

3. Или, может быть, вы можете опубликовать какой-нибудь фрагмент кода, связанный с EditText , чтобы мы могли вместе найти проблему.

4. ваша проблема по-прежнему возникает при удалении drawableEnd или drawableRight (или даже обоих)?
