Question

Depending on the clicked button out of 3 button, different data gets populated in listView.

I’ve used this
onListItemClick snippet

    //ltable refers to list
    String item = ltable.getItemAtPosition(position).toString();
    Intent i = new Intent(getApplicationContext(),NextClass.class);
    i.putExtra("name", item);
    startActivity(i);

Now on any button click, corresponding data gets populated in listView. Then on listItelClick, it navigates to NextClass.class and hence new activity gets launched.

What if I want app to navigate to next view if and only if listView is populated when Gainers or Losers button is pressed????

If listView is populated on Index button click, it should not navigate.

i.e. Clicked button should be captured.

I tried to use flag, but only final variables are permitted within buttonClickListener, so it doesn’t work.

How can I implement this??

ANY HELP WILL BE LIFE-SAVER !!!

Answer 1

Take a class level variable

boolean shouldNavigate = false;

and in onClick() of Index Button. set shouldNavigate to false:

public void onClick(View v)
{
   // Update adapter for Index..
   shouldNavigate = false;
}

But in onClick() of other than Index Button. set shouldNavigate to true:

public void onClick(View v)
{
   // Update adapter for Gainer or Losers..
   shouldNavigate = true;
}

and inside your onItemClick() check for the flag and navigate accordingly

public void onItemClick(AdapterView parent, View view, int position, long id) {
       if(shouldNavigate)
       {
       // you can navigagte...
       }
       else
       {
       // do other task
       }
}
