手机拍照加入相关信息说明

Button imagecapture = (Button)findViewById(R.id.imagecapture);
imagecapture.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
String filename = null;
ImageCaptureCallback iccb = null;
try {
filename = timeStampFormat.format(new Date());
ContentValues values = new ContentValues();
values.put(Media.TITLE, filename);
values.put(Media.DESCRIPTION, "Image capture by camera");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
iccb = new ImageCaptureCallback( getContentResolver().openOutputStream(uri));
} catch(Exception ex ){
ex.printStackTrace();
Log.e(getClass().getSimpleName(), ex.getMessage(), ex);
}
camera.takePicture(mShutterCallback, mPictureCallbackRaw, iccb);
com.froogloid.android.gspot.Park.imageFileName = filename;
}
});


private OutputStream filoutputStream;
public ImageCaptureCallback(OutputStream filoutputStream) {
this.filoutputStream = filoutputStream;
}
@Override
public void onPictureTaken(byte[] data, Camera camera) {
try {
Log.v(getClass().getSimpleName(), "onPictureTaken=" + data + " length = " + data.length);
FileOutputStream buf = new FileOutputStream("/sdcard/dcim/Camera/" + CameraActivity.filename + ".jpg");
buf.write(data);
buf.flush();
buf.close();
// filoutputStream.write(data);
filoutputStream.flush();
filoutputStream.close();
} catch(Exception ex) {
ex.printStackTrace();
}
}
}


主要是这几句的使用
ContentValues values = new ContentValues();
values.put(Media.TITLE, filename);
values.put(Media.DESCRIPTION, "Image capture by camera");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
