Question

我正在尝试刷新每个标签主机，同时单击，我尝试使用addFlags（），但我没有得到该方法。

请检查我的代码。我正在使用FragmentTabHost。是否可以在FragmentTabHost中使用addFlags（）方法。

public class HomeParentFragement extends FragmentActivity implements      View.OnClickListener {

private static final String TAB_1_TAG = "tab_1";
private static final String TAB_2_TAG = "tab_2";
private static final String TAB_3_TAG = "tab_3";
private static final String TAB_4_TAG = "tab_4";
private static final String TAB_5_TAG = "tab_5";
private FragmentTabHost mTabHost;
View view;
Activity mActivity;
private float startX;
ImageButton btn_sidemenu;
Context mContext;
private LinearLayout ll, ll_profile, ll_sidemenu_wallet, ll_sidemenu_postjob, ll_howitwork, ll_help, ll_logout;
/**

Answer 1

tabHost.addTab(tabHost.newTabSpec("tab2")
    .setIndicator("Second Text")
    .setContent(
      new Intent(this, class2.class)
          .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
    ));

这是我的代码在我的最后工作：

 mTabHost.addTab(
                mTabHost.newTabSpec(TAB_1_TAG).setIndicator(getTabIndicator(mTabHost.getContext(), "", getResources().getDrawable(R.drawable.home_tab_1))),
                HomeTabAdvanceSearchFragments.class, null).setContent(new Intent(this, class2.class)
                        .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
        ));

在FragmentTabHost中找不到TabHost addFlags（）
