Question

I have an activity “MyListActivity“. I have an adapter associated with it “MyGridAdapter“. It contains a grid of buttons (say 3). Each button has a “OnClickListner()”.
On click of the 1st button, I would have to take the same action. So, instead of creating similar another activity, I decide to RE-USE the same page. Meaning: I need to call “MyListActivity” but with some modified parameters- increased number of buttons etc…
I tried to use, “invalidate()” on button click. But it re-loads the same page without any changes.

How to call the same activity from a function in the adapter?

My work around for the problem: I created another “tempActivity“. in one of the function I am trying to start the previous activity.
code inside “MyGridAdapter“:

TempActivity temp=new TempActivity();
temp.setIntentObj(<parameters>);

inside “TempActivity”:

Intent intent=new Intent(this,ListActivity.class);        //this gives a "NullPointerException"
startActivity(intent);

In the adapter class, we can start an activity using context.startActivity(intent) I did not know that we can access “start Activity” from adapter… but now it’s working just fine!! Thanks a lot for your recommendation…
