Question

How can I include this code snippet within each activity without explicitly copy and pasting the code in each activity? For example can I just place it in one place and all other activities would Reference this piece of code?

            @Override   
            public boolean dispatchTouchEvent(MotionEvent event) { 
                    // do something   

                    return super.dispatchTouchEvent(event);      

                }

Answer 1

You can put it in a base class that extends Activity and then extend all other activity classes from that.

public class MyActivity extends BaseActivity {
    // Your activity code    
}

public class BaseActivity extends Activity {
    @Override   
    public boolean dispatchTouchEvent(MotionEvent event) { 
        // do something   

        return super.dispatchTouchEvent(event);      
    }
}
