我正在使用 ActionBarSherlock,我无法去从活动中扩展 SherlockFragment 的课程
我需要从 Activity 移动到片段类
这是我的活动课
Intent notificationIntent = new Intent(context,MessagesFragment.class);
Fragment 类就像
public class MessagesFragment extends SherlockFragment implements
OnItemClickListener {
// Layout parameters declaration
private PullToRefreshListView lv_messages;
private ImageView iv_no_data;
private LinearLayout ll_bg;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
getSherlockActivity().getSupportActionBar().setDisplayOptions(
ActionBar.DISPLAY_SHOW_CUSTOM);
getSherlockActivity().getSupportActionBar().setDisplayHomeAsUpEnabled(
true);
getSherlockActivity().getSupportActionBar().setHomeButtonEnabled(true);
getSherlockActivity().getSupportActionBar().setDisplayShowHomeEnabled(
true);
getSherlockActivity().getSupportActionBar().setCustomView(
R.layout.header);
getSherlockActivity().getSupportActionBar().setBackgroundDrawable(
new ColorDrawable(Color.parseColor("#009fe3")));
TextView txt = (TextView) getActivity().findViewById(
R.id.tv_title_header);
Typeface font = Typeface.createFromAsset(getActivity().getAssets(),
"georgia.ttf");
txt.setText("MESSAGES");
txt.setTypeface(font);
return inflater.inflate(R.layout.listview_refreshable, null);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
.
.
.
.
}
如果我使用switchfragment
方法,它会显示很多错误FragmentChangeActivity
private void switchFragment(Fragment fragment) {
if (getActivity() == null)
return;
if (getActivity() instanceof FragmentChangeActivity) {
FragmentChangeActivity fca = (FragmentChangeActivity) getActivity();
fca.switchContent(fragment);
}
}
