I tried several things, such as:
Intent i = new Intent(this, myActivity.class);
startActivity(i)
Where it tells me it cannot resolve symbol 'myActivity'
I tried Context.startActivity and extended the class by Context, at that point it just wants me to implement every single method of Context into my class.
How can I just simply make a new activity visible to the user after an if condition runs into true?
Intent i = new Intent(CurrentActivity.this, myActivity.class);
startActivity(i)
Here myActivity is the name of your second activity (Which you want to open from this intent).
CurrentActivity is the name of your current activity
