Question

我的应用有一个Gridview。单击Gridview单元格，用于打开以清单中的对话框为主题的活动。这很好用。

为了进一步改进应用程序，我想在活动中添加一个viewpager。所以我将SomeClass extends Activity更改为SomeClass extends Fragment。我创建了一个容器（extends FragmentActivity）来保存这个Fragment，我把这个容器作为清单中的对话框主题：

<activity android:name="com.packagename.SomeContainer"  android:theme="@style/Theme.Sherlock.Light.Dialog" />

这不会将Fragment显示为对话框。它显示了我不想要的片段全屏，并且它不会根据内容调整大小，它在活动时会执行。

如何将容器（fragmentactivity）或片段显示为应根据内容调整大小而不显示全屏的对话框？

SomeContainer.java

public class SomeContainer extends SherlockFragmentActivity {

    private SomeAdapter mAdapter;
    private ViewPager mPager;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        overridePendingTransition(R.anim.pull_in_from_left, R.anim.hold);
        setContentView(R.layout.layout_events);

        getWindow().setLayout(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);


        Intent intent = getIntent();
        String date_string = intent.getStringExtra("date_string");


        mAdapter = new SomeAdapter(getSupportFragmentManager(), date_string);

        mPager = (ViewPager) findViewById(R.id.eventspager);
        mPager.setAdapter(mAdapter);
    }

    @Override
    protected void onPause() {
        overridePendingTransition(R.anim.hold, R.anim.pull_out_to_left);
        super.onPause();
    }


    public static class SomeAdapter extends FragmentPagerAdapter {
        String date;
        FragmentManager fm;
        public SomeAdapter(FragmentManager fm, String date) {
            super(fm);
            this.date = date;
            this.fm = fm;
        }

        @Override
        public int getCount() {
            return 3;
        }

        @Override
        public Fragment getItem(int position) {
            switch (position) {
            case 0:
                return SomeFragment.newInstance(date);
            case 1:
                return SomeFragment1.newInstance(date);
            case 2:
                return SomeFragment2.newInstance(date);

            default:
                return null;
            }
        }
    }
}

SomeFragment.java

public class SomeFragment extends DialogFragment  {

    String date_string;

    public static SomeFragment newInstance(String date) {
        SomeFragment someFragment = new SomeFragment();

        Bundle args = new Bundle();
        args.putString("date", date);
        someFragment.setArguments(args);

        returnsomeFragment;
    }

     /** Called when the activity is first created. */

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

        View v =  inflater.inflate(R.layout.events, container, false);

        //getActivity().getWindow().setLayout(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

        date_string = getArguments().getString("date");

        //do something

        return v;
    }
 }

FragmentActivity中的Viewpager主题为Dialog
