Java 为1.5开发的应用程序未在2.2 android上运行
我从在线教程中获得了查看大图像的代码。 它在1.5中运行良好,但是当我使用Android2.2库时,它不起作用。(我的应用程序使用2.2) 我一直在寻找这个问题的答案,但运气不好。我怀疑这可能与drawable文件夹有关? 图像加载,但无法执行缩放或移动图像等操作Java 为1.5开发的应用程序未在2.2 android上运行,java,android,Java,Android,我从在线教程中获得了查看大图像的代码。 它在1.5中运行良好,但是当我使用Android2.2库时,它不起作用。(我的应用程序使用2.2) 我一直在寻找这个问题的答案,但运气不好。我怀疑这可能与drawable文件夹有关? 图像加载,但无法执行缩放或移动图像等操作 private void updateDisplay(){ calculateSourceRect(current_centerX, current_centerY, current_scale); //where
