android-camera-intent

问题 Hi, I am creating a simple Android app which allows user to select photo from either photo gallery or take one using camera. After getting the selected photo, I will start another activity to do something with the photo. However I have some problem displaying the photo in another activity. Here is the first activity to get photo: public class GetPhoto extends Activity implements OnClickListener { ImageButton ibPhotoLib; ImageButton ibCamera; final static int FROM_CAMERA = 0, FROM_PHOTOLIB = 1

问题 I use the following code to kick off the camera, however, 3/4's of the time, the photo does not save to memory. This only occurs on the Galaxy SIII. It works on the Nexus S and Nexus One public void photoNew() { holdingImage = getContentResolver().insert(MUtil.genImgUri(), new ContentValues()); Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); Bundle extras = new Bundle(); extras.putParcelable(MediaStore.EXTRA_OUTPUT, holdingImage); extras.putBoolean("return-data", true); i.putExtras

问题 I have went through several documentation and stacks, however I'm not quite sure how do I implement this... And help or sample codes would really help me understand more. Here are the sets of codes that runs the camera and it's working perfectly fine, my next question is, how do I let it automatically saved into phone gallery? @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_home); tvCameraTiles = (TextView)

问题 Is it possible to take a picture with out opening camera ? I tried with intents but its opening camera, but i don't want to open camera.I tried following Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(takePictureIntent, 1); and after that receiving the activity.But how to do with out opening the camera? 回答1: Yes it is possible for that use SurfaceHolder.Callback Interface . And @TargetApi(9) public void surfaceCreated(SurfaceHolder holder){ Log

问题 Hi I want to show a rectangle in camera so that when the user takes snap only the region inside the rectangle can be processed. Any idea how can I do it?
