ViewPager в простом диалоге
Я хотел бы использовать ViewPager в диалоге, но эпично провалился! Вот весь код. В диалоговом окне отображаются два фрагмента:
Макетыmain.xml
details.xml (Фрагмент макета)
image.xml (Фрагмент макета)
dialog.xml
Main.java
public class Main extends FragmentActivity {
private Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setupUIComponents();
setupListeners();
}
private void setupUIComponents() {
button = (Button) findViewById(R.id.button);
}
private void setupListeners() {
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
MyDialog dialog = new MyDialog(Main.this);
dialog.startDialog();
}
});
}
}
MyDialog.java
public class MyDialog extends FragmentActivity {
private Dialog dialog;
private Context context;
private CirclePageIndicator mIndicator;
private Main mMain;
private ViewPager mPager;
private FragmentAdapter mAdapter;
public MyDialog(Context context) {
super();
this.context = context;
this.mMain = (Main) context;
}
public void startDialog() {
dialog = new Dialog(context);
dialog.setContentView(R.layout.dialog);
mAdapter = new FragmentAdapter(mMain.getSupportFragmentManager());
mPager = (ViewPager) dialog.findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
mIndicator = (CirclePageIndicator) dialog.findViewById(R.id.indicator);
mIndicator.setViewPager(mPager);
mIndicator.setCurrentItem(0);
dialog.show();
}
}
FragmentAdapter.java
public class FragmentAdapter extends FragmentPagerAdapter {
public FragmentAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int which) {
switch (which) {
case 0:
ImageFragment imageFragment = new ImageFragment();
return imageFragment;
case 1:
DetailFragment detailsFragment = new DetailFragment();
return detailsFragment;
}
return null;
}
@Override
public int getCount() {
return 2;
}
}
DetailsFragment.java
public class DetailFragment extends Fragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View view = inflater.inflate(R.layout.details, container, false);
TextView textView = (TextView) view.findViewById(R.id.detailsText);
textView.setText("Testing");
return view;
}
}
ImageFragment.java
public class ImageFragment extends Fragment {
public ImageFragment() {
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View view = inflater.inflate(R.layout.image, container, false);
ImageView imageView = (ImageView) view.findViewById(R.id.imageView1);
imageView.setImageDrawable(getResources().getDrawable(R.drawable.ic_launcher));
return view;
}
}
Для быстрого суммирования кода запускается Main.java, нажатие на кнопку запускает диалог с двумя фрагментами в пейджере представления.
Есть трассировка стека:

Опять же, возможно ли отображать фрагменты в окне просмотра в диалоге? И если да, то где я ошибся?
