Android Infinite Looping Gallery

Hey there,
For a very long time i had been watching people struggling for developing a Infinite Looping Gallery in Android.

Saw very different solutions... some seriously complicated and some ... Not even close to solutions. So, drafted a small snippet which details about how you can create your (Virtually) Infinite Gallery.

Virtually -> No we are not going to use any thing like Integer.MAX_VALUE for number of elements in the list. No crazy circular linked list or anything of that sort and yes no copy pasting from Android Source.

Enough talk, lets code :D

All you need is a Gallery from android and some small peice of code.

Associate this listener to your Gallery

R.drawable.d,R.drawable.e,R.drawable.f,
R.drawable.g,R.drawable.h,R.drawable.i,

// Associate it to your gallery.

public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
if (arg2 < ImageAdapter.ADDED_EXTRA / 2)
((Gallery) findViewById(R.id.gallery1)).setSelection(
mImageIds.length + 2, false);
if (arg2 > mImageIds.length + ImageAdapter.ADDED_EXTRA / 2) {
((Gallery) findViewById(R.id.gallery1)).setSelection(4, false);
}
}


public void onNothingSelected(AdapterView<?> arg0) {
((Gallery) findViewById(R.id.gallery1)).setSelection(3, false);
}
};

In your Adapter just need to modify 2 places.

yeah that's it.. nothing more... you are ready with you infinite looping circular gallery.

Sharing your PC Internet to Android Device (Wifi)

I had been stuck in situations when i was not able to use any 3G or Wifi (Hotspot) internet (Mostly happens in companies).
So in case you want to share your internet connection to your Android devices. There is a very simple yet powerful tool known as Connectify.

YOU CAN ONLY DO THIS ON WINDOWS 7 AND ABOVE ONLY + YOUR PC SHOULD BE  WiFi ENABLED.

Very handy and easy to use tool. Best part you can use it free.
Just visit the site: www.connectify.me and download the application.

1. Install
2. Wifi is ready to be shared :D
3. Find your wifi network you just created on your mobile
4. Start browsing :)

Hope this info will be useful.


Disclaimer: Connectify is a third party tool which i recently came across, and worked very well for me. In case it is not working for you... Sorry cannot help... 

Showing circle around a point in Android (Code)

I had been trying to draw circle around my GeoPoint on the maps. I came across several links, the only limitation in all of them was that i was not able to see my circle growing like Google maps and stuff when i zoom in my maps.

So, finally i had to do this....
Here is a reference for the same...  feel free to use it :)


 public MyOverlay(Drawable defaultMarker, Context context, GeoPoint gp) {
super(defaultMarker, context);
mContext = context;
globalGeoPoint = new GeoPoint(gp.getLatitudeE6(), gp.getLongitudeE6());
maxSizeAreaGP = new GeoPoint(gp.getLatitudeE6()+10000,
gp.getLongitudeE6());
}

private Context mContext;
private GeoPoint globalGeoPoint;
private GeoPoint maxSizeAreaGP;

@Override
public void draw(Canvas canvas, MapView mapV, boolean shadow) {
Projection projection = mapV.getProjection();
if (shadow && projection != null) {
Point pt = new Point();
projection.toPixels(globalGeoPoint, pt);
Point pt1 = new Point();
projection.toPixels(maxSizeAreaGP, pt1);
float circleRadius = (float)Math.sqrt(Math.pow(pt1.x-pt.x, 2)+Math.pow(pt1.y-pt.y, 2));
Paint circlePaint = new Paint(Paint.ANTI_ALIAS_FLAG);
circlePaint.setColor(0x186666ff);
circlePaint.setStyle(Style.FILL_AND_STROKE);
canvas.drawCircle((float) pt.x, (float) pt.y, circleRadius,
circlePaint);
circlePaint.setColor(0xff6666ff);
circlePaint.setStyle(Style.STROKE);
canvas.drawCircle((float) pt.x, (float) pt.y, circleRadius,
circlePaint);
Bitmap markerBitmap = BitmapFactory.decodeResource(
getApplicationContext().getResources(), R.drawable.pin);
canvas.drawBitmap(markerBitmap, pt.x,
pt.y - markerBitmap.getHeight(), null);
super.draw(canvas, mapV, shadow);
}

You can use the above code to show blue circle on the map around a point which will be pan able...
The size of circle will increasing according to zoom level.

Let me know if its not working for you...
