    text
    copied!<p>I have successfully converted my TabActivity into a FragmentActivity, with the tab content being Fragments. I am running two issues:</p> <ol> <li><p>Each of my tabs contain EditText's. When I change the value of an EditText on TAB1, switch to TAB2, and then switch back to TAB1, the value of the EditText has been reset.</p></li> <li><p>If start a new activity from one of my tab Fragments, and then go back to the existing FragmentActivity, then the tab content disappears. I was originally having this issue when using a TabHost, which is why I spent the time to convert everything to Fragments...</p></li> </ol> <p>Regarding #1, I'm assuming the issue has to do with savedInstanceState. I followed Google's <a href="http://developer.android.com/resources/samples/Support4Demos/src/com/example/android/supportv4/app/FragmentTabs.html" rel="nofollow">example</a> exactly, using the following in onCreate() of my FragmentActivity:</p> <pre><code>initialiseTabHost(savedInstanceState); if (savedInstanceState != null) { mTabHost.setCurrentTabByTag(savedInstanceState.getString("tab")); } </code></pre> <p>Additionally, here is my onSaveInstanceState() method of my FragmentActivity:</p> <pre><code>protected void onSaveInstanceState(Bundle outState) { outState.putString("tab", mTabHost.getCurrentTabTag()); super.onSaveInstanceState(outState); } </code></pre> <p>Here is what one of my tab Fragment's looks like:</p> <pre><code>public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { if (container == null) { return null; } return (LinearLayout) inflater.inflate(R.layout.priority_boxes_tab, container, false); } public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); setRetainInstance(true); ArrayList&lt;Supply&gt; list = new ArrayList&lt;Supply&gt;(); // More code here } </code></pre> <p>Should I be doing anything else? I have about 15 EditText fields on the screen. Do I need to somehow save all of those values and set it so that the fields will repopulate with those values the next time?</p> <p>Regarding #2, I have no idea what else I can do. Does anyone have any suggestions?</p> <p>Thanks!</p>
