ImageView

Общая информация

Компонент ImageView предназначен для отображения изображений. Находится в разделе Widgets.

Для загрузки изображения в XML-файле используется атрибут android:src, в последнее время чаще используется атрибут app:srcCompat.

ImageView является базовым элементом-контейнером для использования графики. Можно загружать изображения из разных источников, например, из ресурсов программы, контент-провайдеров. В классе ImageView существует несколько методов для загрузки изображений:

• setImageResource(int resId) — загружает изображение по идентификатору ресурса
• setImageBitmap(Bitmap bitmap) — загружает растровое изображение
• setImageDrawable(Drawable drawable) — загружает готовое изображение
• setImageURI(Uri uri) — загружает изображение по его URI

Метод setImageResource()

Сначала нужно получить ссылку на ImageView, а затем используется идентификатор изображения из ресурсов:

Метод setImageBitmap()

Используется класс BitmapFactory для чтения ресурса изображения в объект Bitmap, а затем в ImageView указывается полученный Bitmap. Могут быть и другие варианты.

Метод setImageDrawable()

Если у вас есть готовое изображение, например, на SD-карте, то его можно использовать в качестве объекта Drawable.

Drawable можно получить и из ресурсов, хотя такой код выглядит избыточным, если можно сразу вызвать setImageResource().

Метод setImageURI()

Берётся URI файла изображения и используется в качестве источника изображения. Этот способ годится для работы с локальными изображениями.

Загружаем Drawable через URI.

Другие методы

Также вам часто придется использовать методы, связанные с размерами и масштабированием: setMaxHeight(), setMaxWidth(), getMinimunHeight(), getMinimunWidth(), getScaleType(), setScaleType().

Масштабирование через свойство Scale Type

Для масштабирования картинки в ImageView есть свойство Scale Type и соответствующий ему атрибут android:scaleType и перечисление ImageView.ScaleType.

• CENTER
• CENTER_CROP
• CENTER_INSIDE
• FIT_CENTER
• FIT_START
• FIT_END
• FIT_XY
• MATRIX

Чтобы увидеть разницу между разными режимами, желательно использовать большую картинку, превосходящую по ширине экрана устройства. Допустим, у нас есть простенькая разметка:

Для наглядности я задал красный цвет для фона ImageView.

Режим android:scaleType=»center» выводит картинку в центре без масштабирования. Если у вас будет картинка большего размера, то края могут быть обрезаны.

Режим android:scaleType=»centerCrop» также размещает картинку в центре, но учитывает ширину или высоту контейнера. Режим попытается сделать так, чтобы ширина (или высота) картинки совпала с шириной (или высотой) контейнера, а остальное обрезается.

Режим android:scaleType=»centerInside» масштабирует картинку, сохраняя пропорции. Можно увидеть задний фон контейнера, если его размеры отличаются от размера картинки.

Режим android:scaleType=»fitCenter» (по умолчанию) похож на предыдущий, но может не сохранять пропорции.

Если выбрать режим android:scaleType=»fitStart», то картинка прижимается к левому верхнему углу и таким образом заполняет верхнюю половину контейнера.

Значение android:scaleType=»fitEnd» сместит картинку в нижнюю часть контейнера.

Режим android:scaleType=»fitXY» растягивает/сжимает картинку, чтобы подогнать её к контейнеру. Может получиться вытянутая картинка, поэтому будьте осторожны.

Последний атрибут android:scaleType=»matrix» вывел картинку без изменений в левом верхнем углу с обрезанными краями.

Атрибут android:adjustViewBounds=»true»

При использовании атрибута scaleType=»fitCenter» из предыдущего примера Android вычисляет размеры самой картинки, игнорируя размеры ImageView. В этом случае ваша разметка может «поехать». Атрибут adjustViewBounds заставляет картинку подчиниться размеру компонента-контейнера. В некоторых случаях это может не сработать, например, если у ImageView установлен атрибут layout_width=»0dip». В таком случае поместите ImageView в RelativeLayout или FrameLayout и используйте значение 0dip для этих контейнеров.

Загрузка изображения из галереи

Предположим, у вас есть на экране компонент ImageView, и вы хотите загрузить в него какое-нибудь изображение из галереи по нажатию кнопки:

Намерение ACTION_PICK вызывает отображение галереи всех изображений, хранящихся на телефоне, позволяя выбрать одно изображение. При этом возвращается адрес URI, определяющий местоположение выбранного изображения. Для его получения используется метод getData(). Далее для преобразования URI-адреса в соответствующий экземпляр класса Bitmap используется специальный метод Media.getBitmap(). И у нас появляется возможность установить изображение в ImageView при помощи setImageBitmap().

На самом деле можно поступить ещё проще и использовать метод setImageURI.

Сравните с предыдущим примером — чувствуете разницу? Тем не менее, приходится часто наблюдать подобный избыточный код во многих проектах. Это связано с тем, что метод порой кэширует адрес и не происходит изменений. Рекомендуется использовать инструкцию setImageURI(null) для сброса кэша и повторный вызов метода с нужным Uri.

В последних версиях системных эмуляторов два примера не работают. Проверяйте на реальных устройствах.

Получить размеры ImageView — будьте осторожны

У элемента ImageView есть два метода getWidth() и getHeight(), позволяющие получить его ширину и высоту. Но если вы попробуете вызвать указанные методы сразу в методе onCreate(), то они возвратят нулевые значения. Можно добавить кнопку и вызвать данные методы через нажатие, тогда будут получены правильные результаты. Либо использовать другой метод активности, который наступает позже.

Копирование изображений между ImageView

Если вам надо скопировать изображение из одного ImageView в другой, то можно получить объект Drawable через метод getDrawable() и присвоить ему второму компоненту.

Примеры

В моих статьях можно найти примеры использования ImageView.

Невозможно изменить видимость ImageView

У меня есть ListView с помощью настраиваемого адаптера для заполнения ListView.

Как вы можете видеть, видимость ImageView исчезла. Я хочу сделать его видимым для одной конкретной строки. Вот код, который я пробовал, но он не работает …

Я заработал. Я использовал это для запуска активности ListView.

В деятельности ListView,

Затем я добавил это в bindview()

Я заработал. Я использовал это для запуска операции просмотра списка.

В деятельности listview,

Затем я добавил это в bindview ()

Возможно, вы должны сделать это в getView() вашего адаптера

Вы должны сделать это так

Если он работает некоторое время, я могу помочь вам. Случилось так, что всякий раз, когда вы перемещаете список, он снова воссоздает все представления, и в этом случае он никогда не сохраняет последнее состояние зрения. Итак, что вам нужно сделать, это сохранить состояние каждого вашего изображения и в getView (), которое вы должны установить соответственно. Я отправляю один из своих ответов, который может вам помочь. Вот вам небольшой код для вашей помощи: я создам логический arraylist.

Private ArrayList imageview_visible = null;

Затем я установлю состояния всего изображения как false в моем конструкторе:

В своем getView напишите этот код:

Public View getView (int position, View convertView, родительская группа ViewGroup)

Всякий раз, когда вы открываете или скрываете свой вид, просто сохраните его в imageview_visible.set (true или false), это сохранит состояние всех ваших изображений и задает каждый вид изображения соответственно

Используйте LayoutInflater для получения объекта просмотра

Попробуйте следующий код следующим образом:

Это работает для меня … Это может вам помочь.

Я столкнулся с аналогичными проблемами, когда несколько виджетов появлялись для некоторых строк, но не для других. Проблемы были вызваны переработкой. Я не совсем уверен, что это ваша проблема здесь, но вы все равно должны ее обработать. Фокус в том, чтобы установить видимость для каждой строки; А не только для строки, которую вы хотите отобразить / исчезнуть.

В противном случае вы предполагаете, что для позиций, отличных от 0, видимость GONE, но это может быть не так, если вы хотите пересмотреть вид. Кстати, я делаю эту работу в bindView. Не уверен, что это технически правильно.

У меня такая же проблема … я решил с нестандартным решением, но работал для меня …

Импорт R из Android

И iv.setVisibility(View.VISIBLE); И iv.setVisibility(ImageView.VISIBLE); Исправлены, но лучше использовать View вместо ImageView потому что VISIBLE & GONE определены в классе View .

Вы больше всего меняете как видимость ( VISIBLE и GONE ) в том, if . как:
