我想在 Tab 中显示 ListView(选择此选项卡后我希望 ListView 出现),所以我创建了 Fragment 类并将 ListView 代码放入其中。现在的主要问题是将片段对象传递给 tabListener。请在此处发布示例,或者更好地展示如何在我的代码中执行此操作。无论如何,任何帮助将不胜感激。
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.Tab tabOne = actionBar.newTab().setText("One");
ActionBar.Tab tabTwo = actionBar.newTab().setText("Two");
tabOne.setTabListener(new tabListener());
tabTwo.setTabListener(new tabListener());
actionBar.addTab(tabOne);
actionBar.addTab(tabTwo);
}
protected class tabListener implements ActionBar.TabListener {
@Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
}
@Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
};
public class FirstFragment extends ListFragment {
private ArrayList<Cinemas> cinema;
private CinemasAdapter cinemaAdapter;
private ListView list;
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
cinema = new Handler().handle();
cinemaAdapter = new CinemasAdapter(MainActivity.this, R.layout.movie_data_row, cinema);
setListAdapter(cinemaAdapter);
}
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
Cinemas movie = cinemaAdapter.getItem(position);
Intent intent = new Intent (MainActivity.this, More.class);
intent.putExtra("Cinemas", movie);
intent.putExtra("data", movie.getBitmap());
Bundle translateBundle =
ActivityOptions.makeCustomAnimation(MainActivity.this,
R.anim.slide_in_left, R.anim.slide_out_left).toBundle();
startActivity (intent, translateBundle);
}
}
}
