如何隐藏在一个片段中的动作条?
我使用AppCompat我在我的应用程序的主题。另外,我使用的是viewpager管理一些片段。 现在,我想隐藏动作条在我的片段之一。我怎样才能做到这一点。我试图在片段像这样
I am using AppCompat for my theme in my app. Also, I am using a viewpager to manage some fragments. Now I would to hide the actionbar in one of my fragments. How can I do that. I tried to hide the actionbar manually in the fragment like this
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActionBarActivity activity = (ActionBarActivity) this.getActivity();
ActionBar aBar = activity.getSupportActionBar();
aBar.hide();
}
但这隐藏动作条为所有片段。任何想法?
在加载其他片段致电(例如在onResume):
When you load other fragments call (for example in onResume):
aBar.show();
编辑:
在你想要有演出的每个片段中的动作条把下面的方法:
in each fragment that you want to have show the ActionBar put the following method:
@Override
public void onResume() {
super.onResume();
aBar.show();
}
在片段中您不想要的操作栏显示OnResume方法做到这一点:
in the OnResume method of the Fragment which you don't want the action bar to show do this:
@Override
public void onResume() {
super.onResume();
aBar.hide();
}
由于您使用的视图寻呼机我假设你正在使用code类似于:
SInce you're using the view pager I assume you're using code similar to:
http://developer.android.com/reference/安卓/支持/ V4 /视图/ ViewPager.html
在这种情况下,在该方法中:
In which case in this method:
@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
Object tag = tab.getTag();
for (int i=0; i<mTabs.size(); i++) {
if (mTabs.get(i) == tag) {
mViewPager.setCurrentItem(i);
// add check here to determine if the selected item is the fragment you want to hide the action bar in...
// if so call aBar.hide();
// for example:
if(i == MY_NO_BAR_FRAGMENT) {
// when you set up the view fragment, you would set MY_NO_BAR_FRAGMENT to the index of that fragment in the view pagers list of pages.
aBar.hide();
}
}
}
}
