How do I get a button to open another activity?

Question

I\'ve added a button to my activity XML file and I can\'t get it to open my other activity. Can some please tell me step by step on how to do this?

Answer 1

Apply the following steps:

1. insert new layout xml in folder layout
2. rename window2
3. add new button and add this line: android:onClick="window2"

mainactivity.java

public void openWindow2(View v) {
        //call window2
        setContentView(R.layout.window2);           
    }
}
