我正在准备一个黑莓应用程序,其中我准备 HTTP 连接,并从一个 URL 中显示屏幕上的图像。
现在,我在其它屏幕上的触摸听器上显示此图像, 并想要用该图像在 URL 上执行缩放插件功能。
图像不在我的设备内存中, 直接从 HTTP 连接中显示。 我想在 5. 0+ 设备上运行此应用程序。 请建议我如何做到这一点?
请尝试以下步骤:
从 URL 获取图像 。
创建 < a href=>" "http://www.blakberry.com/ developers/docs/5.0.0api/net/rim/device/api/ui/extension/container/ ZomomScreen.html" rel="nofollow" @oomScreen 实例并显示它 。
private void showImage(EncodedImage image) {
synchronized (UiApplication.getEventLock()) {
UiApplication.getUiApplication().pushScreen(new ZoomScreen(image));
}
}
