Pass arguments from a fragment to a fragment inside a tabhost

Question

in my app I need to pass two strings from one fragment to another fragment, and finally to a last fragment. Basically there is an activity with a FrameLayout, in which the various fragment are replaced.

The problem is that I think I'm doing too many steps, and it takes too much time in this way. Is there a faster way? I'm getting confused.

Here is my code:

Frag1.java

//...Initiate frag2...

//Pass strings as arguments
Bundle args = new Bundle();
args.putString("String A", edittext1.getText().toString());
args.putString("String B", edittext2.getText().toString()); 
frag2.setArguments(args);

//Replace this fragment with the frag2 that has tabhost in it
manager.beginTransaction()
.replace(R.id.container, frag2).addToBackStack(null).commit();

Frag2.java

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    Resources resources = getActivity().getResources();

    mRoot = inflater.inflate(R.layout.frag2, container, false);

    //Get tabhost and set it up
    mTabHost = (TabHost) mRoot.findViewById(R.id.tabhost);
    mTabHost.setup();

    FragmentManager manager = getFragmentManager();

    //Get the arguments again, and pass it to the fragment that will go inside tab1
    Bundle args = new Bundle();
    args.putString("String A", getArguments().getString("String A"));
    args.putString("String B", getArguments().getString("String B"));

    //...Initiate frag3...

    frag3.setArguments(args);

    //Add it to the tab
    manager.beginTransaction().add(R.id.tab1, frag3).commit();


    //Set content of tabs
    TabSpec spec1 = mTabHost.newTabSpec("tab1");
    spec1.setIndicator("tab1");
    spec1.setContent(R.id.tab1);

    TabSpec spec2 = mTabHost.newTabSpec("tab2");
    spec2.setIndicator("tab2");
    spec2.setContent(R.id.tab2);

    mTabHost.addTab(spec1);
    mTabHost.addTab(spec2);

    return mRoot;
}

Frag2 Layout with tabhost, it may be useful

<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#EFEFEF" >

<TabWidget
    android:id="@android:id/tabs"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" />

<FrameLayout
    android:id="@android:id/tabcontent"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <FrameLayout
        android:id="@+id/tab1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="60dp" >
    </FrameLayout>

    <FrameLayout
        android:id="@+id/tab2"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:paddingTop="60dp" >
    </FrameLayout>

</FrameLayout>

</TabHost>

Frag3.java

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.frag3, container, false);

    //Recover again the strings..
    stringA = getArguments().getString("String A");
    stringB = getArguments().getString("String B");

//Recover TextViews in tab1
TextView tv1 = (TextView) rootView.findViewById(R.id.tv1);
TextView tv2 = (TextView) rootView.findViewById(R.id.tv2);

//...Do something with strings...

//Set text of them with strings
tv1.setText(String.valueOf(stringA));
tv2.setText(String.valueOf(stringB));

    return rootView;
}

Urgh tab host, your problems started there. It sounds like as you say the ui design is flawed. I would add a simple image that explains what you are trying to do showing the different steps. — Graham Smith, Mar 01 '14 at 21:46

I think the simplest and easiest way of doing what you need is using SharedPreferences. You can store whatever you need depending on its datatype and recover it anywhere within your application.

The reference is here
And here is a good example.

Thanks I was thinking about it too, now that you've confirmed, i'll try it :) – Effe Mar 01 '14 at 23:09
