如何在没有预览的情况下从前摄像头捕获图片并将其保存到SD卡。
请帮助我的源代码。
最佳答案
public void takePictureNoPreview(Context context){
// open back facing camera by default
Camera myCamera=Camera.open();
if(myCamera!=null){
try{
//set camera parameters if you want to
//...
// here, the unused surface view and holder
SurfaceView dummy=new SurfaceView(context)
myCamera.setPreviewDisplay(dummy.getHolder());
myCamera.startPreview();
myCamera.takePicture(null, null, getJpegCallback()):
}finally{
myCamera.close();
}
}else{
//booo, failed!
}
private PictureCallback getJpegCallback(){
PictureCallback jpeg=new PictureCallback() {
@Override
public void onPictureTaken(byte[] data, Camera camera) {
FileOutputStream fos;
try {
fos = new FileOutputStream("test.jpeg");
fos.write(data);
fos.close();
} catch (IOException e) {
//do something about it
}
}
};
}
}
