In this tutorial i want to show you some common usefull convertings.

Drawable d =new BitmapDrawable(bitmap);
Convert imageview to bitmap:
ImageView image=new ImageView(context); Bitmap viewBitmap = Bitmap.createBitmap(i.getWidth(),i.getHeight(),Bitmap.Config.ARGB_8888);//i is imageview which u want to convert in bitmap Canvas canvas = new Canvas(viewBitmap); image.draw(canvas);
Convert List
static String[] convert(List<String[]> from) { ArrayList<String> list = new ArrayList<String>(); for (String[] strings : from) { Collections.addAll(list, strings); } return list.toArray(new String[list.size()]); }
Example of using the function:
public static void main(String[] args) { List<String[]> list = new ArrayList<String[]>(); list.add(new String[] { "a", "b" }); list.add(new String[] { "c", "d", "e" }); list.add(new String[] { "f", "g" }); String[] converted = convert(list); System.out.print(converted.toString()); }
Convert seconds to date time string:
SimpleDateFormat formatter = new SimpleDateFormat("EEEE, MMMM d, yyyy HH:mm"); String dateString = formatter.format(new Date(seconds * 1000L));
