Question

I’m trying to make moving pictures (using your finger) + ViewPagerIndicator (dots)

The problem is that I do not want to start. Something he does not fit in the layout this line is 17

android:name=".PlaceSlideFragment"

PlaceDetailsFragment

public class PlaceDetailsFragment extends SherlockFragment {
    PlaceSlidesFragmentAdapter mAdapter;
    ViewPager mPager;
    PageIndicator mIndicator;

    public static final String TAG = "detailsFragment";

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.main,
                container, false);

        mAdapter = new PlaceSlidesFragmentAdapter(getActivity()
                .getSupportFragmentManager());

        mPager = (ViewPager) view.findViewById(R.id.pager);
        mPager.setAdapter(mAdapter);

        mIndicator = (CirclePageIndicator) view.findViewById(R.id.indicator);
        mIndicator.setViewPager(mPager);
        ((CirclePageIndicator) mIndicator).setSnap(true);

        mIndicator
                .setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
                    @Override
                    public void onPageSelected(int position) {
                        Toast.makeText(PlaceDetailsFragment.this.getActivity(),
                                "Changed to page " + position,
                                Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onPageScrolled(int position,
                            float positionOffset, int positionOffsetPixels) {
                    }

                    @Override
                    public void onPageScrollStateChanged(int state) {
                    }
                });
        return view;
    }

}

PlaceSlideFragment

public final class PlaceSlideFragment extends Fragment {
    int imageResourceId;

    public PlaceSlideFragment(int i) {
        imageResourceId = i;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        ImageView image = new ImageView(getActivity());
        image.setImageResource(imageResourceId);

        LinearLayout layout = new LinearLayout(getActivity());
        layout.setLayoutParams(new LayoutParams(null));

        layout.setGravity(Gravity.CENTER);
        layout.addView(image);

        return layout;
    }
}

PlaceSlidesFragmentAdapter

public class PlaceSlidesFragmentAdapter extends FragmentPagerAdapter implements
IconPagerAdapter {

private int[] Images = new int[] { R.drawable.real_pixels, R.drawable.real_pixels,
    R.drawable.real_pixels, R.drawable.real_pixels

};

protected static final int[] ICONS = new int[] { R.drawable.ic_launcher,
    R.drawable.ic_launcher, R.drawable.ic_launcher, R.drawable.ic_launcher };

private int mCount = Images.length;

public PlaceSlidesFragmentAdapter(FragmentManager fm) {
super(fm);
}

@Override
public Fragment getItem(int position) {
return new PlaceSlideFragment(Images[position]);
}

@Override
public int getCount() {
return mCount;
}

@Override
public int getIconResId(int index) {
return ICONS[index % ICONS.length];
}

public void setCount(int count) {
if (count > 0 && count <= 10) {
    mCount = count;
    notifyDataSetChanged();
}
}
}

MainActivity

public class MainActivity extends FragmentActivity{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }


}

main(layout)

<?xml version="1.0" encoding="utf-8"?>

Answer 1

prefix it with the package name

let assume the package that PlaceSlideFragment lives in is com.example
so change it like this

<fragment   
            android:name="com.example.PlaceSlideFragment"
            android:id="@+id/fragment"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

make sure you have a public empty constructor

public PlaceSlideFragment(){

}

Edit

If you are using the Fragment from the compatiblity library make sure that your Activity is FragemntActivity otherwise it will fail to inflate it now if you are using Sherlock Libary change it to SherlockFragmentActivity
