How to add picture to my own gallery


I want to take a photo from my App and save this in my own gallery. After this I need the full name of the photo. With

private void dispatchTakePictureIntent(int actionCode) {
  Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
  this.startActivityForResult(takePictureIntent, actionCode);
}

the photo will be saved in the default gallery. If I read the documentation right than I can set the name with

takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, "MyFileName");

How can I create my own gallery and save the image there instead of the default gallery?

After taking the photo and saving in a gallery the result function will be called. How can I get besides the image the full name of the file.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  switch(requestCode){
    case actionCode:
      // get the image
      InputStream stream = this.getContentResolver().openInputStream(data.getData());

      // How to get the file name?
      break;
    default:
  }
}

After setting the name with the extra the onActivityResult function won't be called. Without this extra I get the image to utilize.


Solution

  • Capture image like this:

    private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;
    private Uri fileUri;
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    
    // create Intent to take a picture and return control to the calling application
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    
    fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
    
    // start the image capture Intent
    startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
    }
    

    getOutputMediaFileUri like this:

    public static final int MEDIA_TYPE_IMAGE = 1;
    public static final int MEDIA_TYPE_VIDEO = 2;
    
    /** Create a file Uri for saving an image or video */
    private static Uri getOutputMediaFileUri(int type){
      return Uri.fromFile(getOutputMediaFile(type));
    }
    
    /** Create a File for saving an image or video */
    private static File getOutputMediaFile(int type){
    // To be safe, you should check that the SDCard is mounted
    // using Environment.getExternalStorageState() before doing this.
    
    File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
              Environment.DIRECTORY_PICTURES), "MyCameraApp");
    // This location works best if you want the created images to be shared
    // between applications and persist after your app has been uninstalled.
    
    // Create the storage directory if it does not exist
    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            Log.d("MyCameraApp", "failed to create directory");
            return null;
        }
    }
    
    // Create a media file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    File mediaFile;
    if (type == MEDIA_TYPE_IMAGE){
        mediaFile = new File(mediaStorageDir.getPath() + File.separator +
        "IMG_"+ timeStamp + ".jpg");
    } else if(type == MEDIA_TYPE_VIDEO) {
        mediaFile = new File(mediaStorageDir.getPath() + File.separator +
        "VID_"+ timeStamp + ".mp4");
    } else {
        return null;
    }
    
    return mediaFile;
    }
    

    and get saved image fileUri like this:

    private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;
    private static final int CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE = 200;
    
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
        if (resultCode == RESULT_OK) {
            // Image captured and saved to fileUri specified in the Intent
            Toast.makeText(this, "Image saved to:\n" +
                     data.getData(), Toast.LENGTH_LONG).show();
        } else if (resultCode == RESULT_CANCELED) {
            // User cancelled the image capture
        } else {
            // Image capture failed, advise user
        }
    }
    
    if (requestCode == CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE) {
        if (resultCode == RESULT_OK) {
            // Video captured and saved to fileUri specified in the Intent
            Toast.makeText(this, "Video saved to:\n" +
                     data.getData(), Toast.LENGTH_LONG).show();
        } else if (resultCode == RESULT_CANCELED) {
            // User cancelled the video capture
        } else {
            // Video capture failed, advise user
        }
    }
    }
