Android pass variable to an intent

Question

I have an class to start a new activity and I have a function inside that creates an intent. I need to pass MainActivity.class variable to that function. Normally I do it like this.

Intent intent = new Intent(context, MainActivity.class);

And I wan't to have something like this:

Intent intent = new Intent(context, variable);

So I wan't to change activity to start basically. Is this possible?

Do you mean you want to pass a class variable to the Intent? — Murat Karagöz, Jul 13 '17 at 11:30

If I understood you correctly you want to use reflection to get the class name.

Class someActivity = Class.forName(getPackageName() + "MainActivity");
Intent intent = new Intent(context, someActivity);
startActivity(intent);

Exactly. If I edit this code like this I can get what I wanted. – Opsoftware Jul 13 '17 at 11:41
try { Class someActivity = Class.forName(getPackageName() + ".MainActivity"); Intent intent = new Intent(getApplicationContext(), someActivity); startActivity(intent); }catch (Exception e){ e.printStackTrace(); } – Opsoftware Jul 13 '17 at 11:41

You are looking for this one.

private void callActivity(Activity activity,Class<?> className)
{
    Intent intent = new Intent(activity, className);
    startActivity(intent);
}

Just pass activity from where you call another activity and the className which you need to call.

private void callActivity(Context context,Class<?> className)
{
    Intent intent = new Intent(context, className);
    startActivity(intent);
}
