Circular gallery with images from remote site?
I am using this code to retreive images from a url. and set them in a gallery view.
How do i go about making the Gallery circular or make the images go in a circle versus straight across the screen. Here is my imageAdapter that extends BaseAdapter...
public class ImageAdapter extends BaseAdapter {
/** The parent context */
private Context myContext;public ImageAdapter() {
// TODO Au开发者_运维知识库to-generated constructor stub
}
/** URL-Strings to some remote images. */
public String[] myRemoteImages = {imageUrl,imageUrl2,imageUrl3,imageUrl4};
/** Simple Constructor saving the 'parent' context. */
public ImageAdapter(Context c) { this.myContext = c; }
/** Returns the amount of images we have defined. */
public int getCount() {
return 10000;
}
/* Use the array-Positions as unique IDs */
public Object getItem(int position) {
return position; }
public long getItemId(int position) {
return position;
}
/** Returns a new ImageView to
* be displayed, depending on
* the position passed. */
public View getView(int position, View convertView, ViewGroup parent) {
ImageView i = new ImageView(this.myContext);
try {
URL aURL = new URL(myRemoteImages[position]);
URLConnection conn = aURL.openConnection();
conn.setUseCaches(true);
conn.connect();
InputStream is = conn.getInputStream();
/* Buffered is always good for a performance plus. */
BufferedInputStream bis = new BufferedInputStream(is);
/* Decode url-data to a bitmap. */
Bitmap bm = BitmapFactory.decodeStream(bis);
bis.close();
is.close();
Log.v(imageUrl, "Retrieving image");
/* Apply the Bitmap to the ImageView that will be returned. */
i.setImageBitmap(bm);
} catch (IOException e) {
Log.e("DEBUGTAG", "Remtoe Image Exception", e);
/* Image should be scaled as width/height are set. */
i.setScaleType(ImageView.ScaleType.FIT_CENTER);
/* Set the Width/Height of the ImageView. */
if(Build.VERSION.SDK_INT >= 11){
i.setLayoutParams(new Gallery.LayoutParams(450, 300));
return i;
}
else{
i.setLayoutParams(new Gallery.LayoutParams(125, 125));
return i;
}
}
return i;
}
/** Returns the size (0.0f to 1.0f) of the views
* depending on the 'offset' to the center. */
public float getScale(boolean focused, int offset) {
/* Formula: 1 / (2 ^ offset) */
return Math.max(0, 1.0f / (float)Math.pow(2, Math.abs(offset)));
}
}
And here i set the imageAdapter to the Gallery with this method.
((Gallery) findViewById(R.id.gallery))
.setAdapter(new ImageAdapter(MainMenu.this));
How do i go about making the gallery circular, taking that the images are downloaded from a url?
EDIT: Like a carousel. Like this
