Question

Is there a way to say if an activity is selected then do something?

I dont know the statement which is why i am asking this question, but similar to this:

if(myactivity.isselected(true)){
webview3.reload();}

If you are using tabs, then onTabChange() is the correct event for that. Not all tabs are individual activities. Not even necessarily different layouts. Then you can check to see if the selected tab is the activity like this

public void onTabChange(View v, int id) {
switch (v.getId()) {
case (R.id.tab1) {
//Do this
break;
}
}

The tabhost supports alot of functionality. Another funcitonis getTab() which will return the id (as an int) of the tab selected. Heres a link to the documentation http://developer.android.com/reference/android/widget/TabHost.html
