我是新使用ViewPagers
和Fragments
在一起。我的應用程序在啓動時有一個ListView
,這會使用戶根據傳遞的ID來查看詳細信息視圖。我遇到的問題是,細節視圖與列表視圖有不同的佈局。 ViewPager
處於初始屏幕的佈局,所以當使用ViewPager
時,佈局保留原始佈局,該佈局基本上只是底部的狀態欄,當用戶處於詳細視圖時應該消失。ViewPager帶有不同佈局的片段
這是我到目前爲止有:
main.xml中(啓動時的初始佈局,狀態欄)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
>
<!-- Footer -->
<TextView
android:id="@+id/status"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
/>
<!-- Footer -->
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_above="@id/status
/>
</RelativeLayout>
Main.class
public class Main extends SherlockFragmentActivity
{
private static int NUMBER_OF_PAGES;
private ViewPager mViewPager;
private MyFragmentPagerAdapter mMyFragmentPagerAdapter;
private static List<Fragment> fragments;
@Override
public void onCreate(final Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.main);
mViewPager = (ViewPager)findViewById(R.id.viewpager);
mMyFragmentPagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager());
mViewPager.setAdapter(mMyFragmentPagerAdapter);
NUMBER_OF_PAGES = 5;
fragments = new ArrayList<Fragment>();
fragments.add(new ListingFragment()); //initial screen that just a ListView
fragments.add(DetailsFragment.newInstance(1));
fragments.add(DetailsFragment.newInstance(2));
fragments.add(DetailsFragment.newInstance(3));
fragments.add(DetailsFragment.newInstance(4));
}
private static class MyFragmentPagerAdapter extends FragmentStatePagerAdapter {
public MyFragmentPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int index) {
return fragments.get(index);
}
@Override
public int getCount() {
return NUMBER_OF_PAGES;
}
}
}
Details.xml(沒有狀態欄的細節視圖)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView android:id="@android:id/list"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
/>
</RelativeLayout>
DetailsFragment.class
public class DetailsFragment extends SherlockFragmentActivity
{
private int detailId;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
}
@Override
public void onActivityCreated(final Bundle icicle)
{
super.onActivityCreated(icicle);
}
public static DetailsFragment newInstance(int id) {
DetailsFragment lf = new DetailsFragment();
Bundle bundle = new Bundle();
bundle.putInt("id", id);
lf.setArguments(bundle);
return lf;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.details, container, false);
detailId = getArguments().getInt("id");
return view;
}
}
就是這樣。不過,這應該對我來說非常明顯。 :) 謝謝! –
