My Code:

public class SecondCity extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Boolean customTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); 
        // Set the layout to use
        setContentView(R.layout.main);
        if (customTitleSupported) {
            getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,R.layout.custom_title); 
            TextView tv = (TextView) findViewById(R.id.tv); 
            Typeface face=Typeface.createFromAsset(getAssets(),"BFantezy.ttf");     
            tv.setTypeface(face);
            tv.setText("MY PICTURES"); 
        }

        InfiniteGallery galleryOne = (InfiniteGallery) findViewById(R.id.galleryOne);
        galleryOne.setAdapter(new InfiniteGalleryAdapter(this));     
    }

Answer 1

You are getting those red marks as these class are already defined in one of your previous class. Java won’t let have duplicate names. Also it seems you are trying to define same classes for every Actvitiy which is redundant.

Just remove the two classes completely from your SecondActivity java file as they are already defined in a previous activity. I would suggest you to make a separate package where the Adapter and InfiniteGallery are defined and kept to be reused .

public class SecondCity extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Boolean customTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); 
        // Set the layout to use
        setContentView(R.layout.main);
        if (customTitleSupported) {
            getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,R.layout.custom_title); 
            TextView tv = (TextView) findViewById(R.id.tv); 
            Typeface face=Typeface.createFromAsset(getAssets(),"BFantezy.ttf");     
            tv.setTypeface(face);
            tv.setText("MY PICTURES"); 
        }

        InfiniteGallery galleryOne = (InfiniteGallery) findViewById(R.id.galleryOne);
        galleryOne.setAdapter(new InfiniteGalleryAdapter(this));     
    }
}
