android上的相机预览-sdk 1.5版本上的奇怪行 [英] camera preview on android - strange lines on 1.5 version of sdk

问题描述

我正在为Android应用程序开发相机模块.在主应用程序中，当用户单击拍照"按钮时，将打开带有SurfaceView控件的新视图并显示相机预览.当用户单击dpad center时，相机将拍摄照片并将其保存到光盘中.非常简单明了.

I am developing the camera module for an android application. In main application when user clicks on 'take picture' button, new view with SurfaceView control is opened and camera preview is shown. When users click on dpad center, camera takes picture and save it to the disc. Pretty simple and straightforward.

一切都可以在我的设备上正常运行-HTC Tattoo，minsdkversion 1.6

Everything works fine on my device - HTC Tattoo, minsdkversion 1.6

...但是当我在HTC Hero minsdkversion 1.5上测试应用程序时，显示摄像机预览时，会出现一些奇怪的行.

...but when I tested application on HTC Hero minsdkversion 1.5, when camera preview is shown,some strange lines occur.

任何人都知道发生了什么事

p.s.预览已完全崩溃，拍照效果很好

推荐答案

显然，这是Hero bug，在功能surfaceChanged中，开关的宽度和高度参数为

Apparently this is hero bug, in function surfaceChanged switch width and height parameters:

    if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) 
    { 
        parameters.setPreviewSize(h, w); //instead of w,h
    }
