Re: Help to implement TabNavigation

[Jonathan Steele]

you have to drop using Activity for ActionBar Tab and use Fragment.

Here mine Tabbed Activity that will help you

Hi all, i'm starting to develop on android and found this library by chance, i have to say that i loved from the beginning and it seems incredible. Now i only need to start working with it little by little hehe.  (totally noob xD)

I am having problems implementing and adapting the sample of TabNavigation. What i'm trying to do is a TabNavigation, showing different Activitys with its contents. Without SherlockActionBar library, i have it so:
(like tutorial tab of developer.android) 
     
        intent = new Intent().setClass(this, Activity1.class);
        spec = tabHost.newTabSpec("Activity 1").setIndicator("Activity 1",
        res.getDrawable(R.drawable.ic_tab_info))
        .setContent(intent);
        tabHost.addTab(spec);

Now, looking at the source from the sample of TabNavigation of SherlockActionBar:

I put the Tabs:
                     ActionBar.Tab tab1 = getSupportActionBar().newTab();
                     tab1.setText("Activity 1");
                     tab1.setTabListener(this);
                     getSupportActionBar().addTab(tab1);

and in function onTabSelected, as an issue here, i put:

                     int iPosition = tab.getPosition();
                     String tabText = tab.getText().toString();

                     switch(iPosition)
                     {
                            case 0:
                                        Intent intent = new Intent(this, Activity1.class);
                                        startActivity(intent);
                                        break;
                     (...)

If I do this, the Activity is fully open and i lose the Tab menu. :(

I think my problem is just being a nooooooob, i think the problem is how to declare the Activitys. With the first method are Activitys normal, but with SherlockActionBar i think i need to declare them in a particular way... but honestly i can not think how to put it :(

Sorry Jonathan... you will kill me but after a whole day just trying it and having faults... i quit and have to ask you again for help. All about of the fragments is new to me and driving me crazy. Right now I'm trying that each Tab invoke a SherlockFragment with its own layout.xml.

First the main with Tabs, as the sample of TabNavigation of JakeWharton. And then "onTabSelected":

        int iPosition = tab.getPosition();
       
        switch(iPosition)
        {
            case 0:
                    mSelected.setText("Selected: " + tab.getText());
                    break;
            case 1:
                    mSelected.setText("Selected: " + tab.getText());
                    SherlockFragment fragment1 = new SherlockFragment();
                    fragment1.getFragmentManager().findFragmentById(R.id.fragmentA);
                    transaction.replace(R.id.content_frame, fragment1, null);
                  
                    break;
        }

These are the layouts:

fragment_layer.xml
   
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_weight="1"
        android:layout_width="0px"
        android:layout_height="match_parent"
         />

and fragments_a.xml

<fragment
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/fragmentA"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.test.FragmentA" >
       
</fragment>

Hello everyone,

I too am having problems implementing the FragmentTabsPager. Can anyone help me with that? If so, I'll upload the files I'm using :).
