On Android, how do you switch Activity's programatically?

Question

It seems like every example I can find of switching between Activity's involves creating an Intent and passing in the context of a View via an OnClickListener associated with a button.

But what if you just decide you need to switch Activity's? In my case, a Preference value is causing an Activity switch. How do you create an Intent that can cause an Activity switch without an associated OnClickListener?

Answer 1

Intent myIntent = new Intent(this, AvitivityName.class);
startActivity(myIntent)

Should do it for you and you can call that from anywhere in your other activity.

Answer 2

Use PreferenceChangeListener :)

Answer 3

You can create intent in the main activity like this

Intent intent = new Intent(FirstActivity.this, second.class); startActivity(intent);

If you are waiting for result from the second then you should use

StartActivityforresult(intent,request code).

request code can be any integer.

Answer 4

when ever u want to switch activity . u can call these code .

Intent intent = new Intent(this, MyActivity.class);
startActivity(intent);

You can write this code in PreferenceChangeListener.
