我最近修改了我的相机以捕获和显示全尺寸图像，Galaxy Nexus 上的尺寸为 2592 X 1944。我在捕获图像并在预览中显示时尝试使用 LruCache。图像应该在那里是空白。我的 LogCat 上的先前条目告诉我图像已保存。
如何获得完整尺寸的图像来显示？
图片大小通过以下方式获得：
private Size getDesiredPictureSize(Parameters params)
{
//Resolution is widthxheight
Size result=null;
//boolean isDesiredValue=false;
final int minArea=500*500;
final int maxArea=1000*1000;
List<Size> supportedSizeList=params.getSupportedPictureSizes();
for(Size size:supportedSizeList)
{
if(result==null)
result=size;
else
{
int resultArea=result.width*result.height;
int sizeArea=size.width*size.height;
if(resultArea<sizeArea)
{
result=size;
Log.d("CameraPreview", "Result pictureSize has been set to "+result.width+"X"+result.height);
}
}
}
Log.d("CameraPreview", "Picture size has been set to "+result.width+"X"+result.height);
return result;
}
当必须为预览显示图像时，logcat 会显示以下内容：
