Question

Here is my image gallery code. So far, for testing purpose I directly used some manually stored images,

public class Photo_Gallery extends Activity
{    
//---the images to display---
Integer[] imageIDs = {
        R.drawable.a,
        R.drawable.b,
        R.drawable.c,
        R.drawable.d,
        R.drawable.e,
};

@Override    
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.displayview);

    Gallery gallery = (Gallery) findViewById(R.id.gallery1);

    gallery.setAdapter(new ImageAdapter(this));        
    gallery.setOnItemClickListener(new OnItemClickListener() 
    {
        public void onItemClick(AdapterView parent, View v, int position, long id) 
                {                
                    //---display the images selected---
                    ImageView imageView = (ImageView) findViewById(R.id.image1);                
                    imageView.setImageResource(imageIDs[position]);
                }
    });
}

public class ImageAdapter extends BaseAdapter 
{
    private Context context;
    private int itemBackground;

    public ImageAdapter(Context c) 
    {
        context = c;
        //---setting the style---
        TypedArray a = obtainStyledAttributes(R.styleable.Gallery1);
        itemBackground = a.getResourceId(
            R.styleable.Gallery1_android_galleryItemBackground, 0);
        a.recycle();                    
    }

    //---returns the number of images---
    public int getCount() {
        return imageIDs.length;
    }

    //---returns the ID of an item--- 
    public Object getItem(int position) {
        return position;
    }            

    public long getItemId(int position) {
        return position;
    }

    //---returns an ImageView view---
    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imageView = new ImageView(context);
        imageView.setImageResource(imageIDs[position]);
        imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        imageView.setLayoutParams(new Gallery.LayoutParams(75, 60));
        imageView.setBackgroundResource(itemBackground);
        return imageView;
    }
}    

}

And here is the code I used to capture images.

    case R.id.takeSnapBtn:

        try {

            i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(i, imageData);

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

Following is the onActivityResult(),

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {

        Bundle extras = data.getExtras();
        bmp = (Bitmap) extras.get("data");

        imageView.setImageBitmap(bmp);

    }

}

I would be glad if some one provide me an example of how to dynamically update the gallery with images taken from the camera.

Answer 1

Store the images captured from app and read those images from sd card to gallery..

File sdDir = new File("/sdcard/Pictures/YOUR_DIR");
sdDirFiles = sdDir.listFiles();
for (i = 0; i < sdDirFiles.length; i++) {
//ADD to gallery HERE..
}
