Intent and start activity from string

Question

I have a little problem. I want to start activity but in something other way. I know that

Intent i = new Intent(this, ActivityTwo.class); 

Answer 1

Just use....

  Intent intent = new Intent().setClassName(activity,"packageName"+"className");
  startActivity(intent);

Answer 2

Class<?> c =Class.forName("YOUR STRING" );
Intent intent = new Intent(FirstActivity.this, c);
startActivity(intent);

Answer 3

Try this: startActivity(this, Class.forName(yourStringClass));

Answer 4

You can look up a Class by name using Class.forName("MyString")

Answer 5

Here is a code by which you can start activity using the name of the activity

Class<?> c = null;
if(StringClassname != null) {
    try {
        c = Class.forName(StringClassname );
    } catch (ClassNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
Intent intent = new Intent(mail.this, c);
startActivity(intent);

Here class name will be full name of the class with the package name. For example if your package name will be x.y.z and if you have Activity name called A then the full name of the Activity A will be x.y.z.A.
