I'm getting this in logCat when trying to run my app:
java.lang.IllegalStateException: No tab known for tag null
What Im trying to do is to initialize the Tabhost in onCreateView like this:
mTabHost = (FragmentTabHost) mView.findViewById(android.R.id.tabhost);
and then in onPostExecute im doing this:
//setup tabhost
mTabHost.setup(getActivity(), getChildFragmentManager(), R.layout.fragment_comminity);
Log.v("---", "adding tabs");
b = new Bundle();
if (getArguments().getString(IntentConstants.KEYWORD) != null)
if (getArguments().getString(IntentConstants.KEYWORD).length() > 0) {
if (key == null) {
key = getArguments().getString(IntentConstants.KEYWORD);
doTheRequest();
} else {
if (!key.equals(getArguments().getString(IntentConstants.KEYWORD)))
doTheRequest();
}
}
mTabHost.addTab(mTabHost.newTabSpec("clips").setIndicator(getLocalizationString("lblClips")),
CommunityClipsFragment.class, b);
mTabHost.addTab(mTabHost.newTabSpec("clipboards").setIndicator(getLocalizationString("lblClipboards")),
FragmentSearchMyClipboards.class, b);
final int reverseTabs[] = {1, 0};
mTabHost.getTabWidget().setDividerDrawable(R.color.color_translucent_grey);
View v = mTabHost.getTabWidget().getChildTabViewAt(reverseTabs[mTabHost.getCurrentTab()]);
((TextView) v.findViewById(android.R.id.title)).setTypeface(null, Typeface.NORMAL);
((TextView) v.findViewById(android.R.id.title)).setTextColor(Color.parseColor("#a3a3a3"));
v.setBackgroundResource(R.drawable.border);
View v2 = mTabHost.getTabWidget().getChildTabViewAt(mTabHost.getCurrentTab());
v2.setBackgroundColor(getResources().getColor(R.color.transparent));
((TextView) v2.findViewById(android.R.id.title)).setTextColor(getResources().getColor(R.color.color_clipixorange));
v2.setBackgroundResource(R.drawable.border);
mTabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener() {
@Override
public void onTabChanged(String s) {
View v = mTabHost.getTabWidget().getChildTabViewAt(reverseTabs[mTabHost.getCurrentTab()]);
((TextView) v.findViewById(android.R.id.title)).setTypeface(null, Typeface.NORMAL);
((TextView) v.findViewById(android.R.id.title)).setTextColor(Color.parseColor("#a3a3a3"));
// v.setBackgroundColor(getResources().getColor(R.color.transparent));
v.setBackgroundResource(R.drawable.border);
View v2 = mTabHost.getTabWidget().getChildTabViewAt(mTabHost.getCurrentTab());
// v2.setBackgroundColor(getResources().getColor(R.color.transparent));
v2.setBackgroundResource(R.drawable.border);
((TextView) v2.findViewById(android.R.id.title)).setTypeface(null, Typeface.BOLD);
((TextView) v2.findViewById(android.R.id.title)).setTextColor(getResources().getColor(R.color.color_clipixorange));
}
});
progress.setVisibility(View.GONE);
any idea how can I fix this, because I need to first fetch the data from a server and then put the bundle data to the child fragments. Here is my xml:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ProgressBar
android:id="@+id/frag_progress"
style="?android:attr/progressBarStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<FragmentTabHost
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@android:id/tabhost">
<LinearLayout
android:id="@+id/LinearLayout01"
android:orientation="vertical"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<TabWidget
android:id="@android:id/tabs"
android:layout_height="wrap_content"
android:layout_width="fill_parent">
</TabWidget>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
</FrameLayout>
</LinearLayout>
</FragmentTabHost>
</FrameLayout>
</FrameLayout>
and my logCat output:

It looks like the problem is that you are delaying your call to setup() until after the task is executed. It should be called directly after inflating the view.
From the FragmentTabHost docs:
