在我的应用程序中，我想在第一个 Fragment 中放置一个 ListView，并且当我单击一个项目时，我想移动到一个新的 Fragment，这样每个项目在我的代码中都有自己的详细信息。
我实现它以移动到另一个活动，但现在我的经理说它必须转到另一个片段而不是其他活动。我是 Fragment 世界的新手，我不知道该怎么做。经理说我可以使用列表片段，但我没有找到任何有用的代码。
这是我的代码：
public class MainActivity extends FragmentActivity {
SectionsPagerAdapter mSectionsPagerAdapter;
static ProgressDialog pd ;
ViewPager mViewPager;
List<Fragment> fragments ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create the adapter that will return a fragment for each of the three
// primary sections of the app.
fragments = new Vector<Fragment>();
fragments.add(Fragment.instantiate(this, FragmentOne.class.getName()));
fragments.add(Fragment.instantiate(this, FragmentTwo.class.getName()));
fragments.add(Fragment.instantiate(this, FragmentThree.class.getName()));
fragments.add(Fragment.instantiate(this, FragmentFour.class.getName()));
fragments.add(Fragment.instantiate(this, FragmentFive.class.getName()));
fragments.add(Fragment.instantiate(this, FragmentSix.class.getName()));
mSectionsPagerAdapter=new SectionsPagerAdapter(super.getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.pager);
pd = new ProgressDialog(this);
mViewPager.setAdapter(mSectionsPagerAdapter);
//
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
int _pos = position % 6;
return fragments.get(_pos);
}
@Override
public int getCount() {
// Show 3 total pages.
return 6;
}
@Override
public CharSequence getPageTitle(int position) {
final String title_section4="Section4";
final String title_section5="Section5";
final String title_section6="Section6";
final String title_section1="Section1";
final String title_section2="Section2";
final String title_section3="Section3";
Locale l = Locale.getDefault();
switch (position) {
case 0:
return title_section1.toUpperCase(l);
case 1:
return title_section2.toUpperCase(l);
case 2:
return title_section3.toUpperCase(l);
case 3:
return title_section4.toUpperCase(l);
case 4:
return title_section5.toUpperCase(l);
case 5:
return title_section6.toUpperCase(l);
}
return null;
}
}
