Hello
I've created a simple home screen widget for the Android 2.2. It
comprises of a button and a background image only. What im trying to
do is that when user clicks on the button, i show a Toast msg with a
number. This number is to be increased every time button is clicked,
starting from zero.
So ive declared my variable as follows:
public class MainWidget extends AppWidgetProvider {
private static int myNum = 0;
...
And in the onReceive event I do this (after checking the button was
clicked):
myNum += 1;
Toast.makeText(context, "myNum:" + myNum, Toast.LENGTH_LONG).show();
This works fine. Whenever user clicks the button the number is
increased by 1 and displayed on screen. I want this number to be
instance-specific. If i remove the widget from the home screen and add
it back again, the numbering continues from the point where it was
last time. For example if number is currently 4. I remove the widget
and add back and click button, it will display 5. I want it to restart
from 1.
I've tried various declarations:
private int myNum = 0;
int myNum = 0;
static int myNum = 0;
But nothing work. If I remove the "static" keyword then the number
doesn't increase at all. Every time the button is clicked, it keeps
displaying 1. I want the number to be instance-specific i.e. to be
restarted from 1 whenever the widget is removed and added back. Also
if the user places more than one widgets on his home screen then both
the widgets' numbering should be independent from each other. How do I
achieve this? Seems like a simple task but totally confused how to
declare my integer. Please anyone help.
