Problem Description and Question

I'm using tab activity with action bar. In the HOME tab I have GridView which contains some items, like it is shown in the image below (Hot Lines, Taxi, Restaurants etc)

Wen user click on the items in the grid view I want my application to take following actions:

• Change icon of application to grid view item image on which I pressed.
• Change the test near the icon
• Add standard back button near icon, which will go back to grid view screen.
• Change the tab fragment to the one which I specify.

Like it is shown in the image below:

As I never deal with this kind of problems can you please give me example or share some link with me of how I can do this? and can I do this at all?

Answer 1

This might help: Android studio - is possible to add tabs pointing to fragments from designer? It is not exactly what you want, but a good start. If you are willing to put a bit of work in it, you should be able to get what you want. If you have a basic Frame to work with and more specific problems with this matter I will gladly help you out ^^

Answer 2

The first link you can check is THIS .

And you should read more about ActionBar .

The last thing is it's better if you google it first and try to write a code and when you got stuck somewhere share your code with us and ask for help.

Answer 3

You have to use actionbarsherlock library for it.

use android.support.v4.app.FragmentTabHost and TabWidget in the xml as shown below :

<android.support.v4.app.FragmentTabHost 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    style="@style/yourstyle"/>

    <FrameLayout
        android:id="@+id/realtabcontent"
        style="@style/realtabFrameContentStyle" />


       <TabWidget
          android:id="@android:id/tabs"
         style="@style/yourtabstyle" />

</android.support.v4.app.FragmentTabHost>

Use SherlockFragmentActivity for showing the tabs.

In the activities code use following code (preferably in a function) to set the ctionbar icon and text :

activity.getSupportActionBar().setDisplayShowCustomEnabled(true);
activity.getSupportActionBar().setCustomView(R.layout.your_action_barlayout);


((TextView) (activity.getSupportActionBar().getCustomView().findViewById(R.id.action_bar_title))).setText("your title");

        ImageView homeButton = ((ImageView) (activity.getSupportActionBar().getCustomView().findViewById(R.id.your_icon)));
        homeButton.setVisibility(View.VISIBLE);
        homeButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent = new Intent(context, YourHOmeActivity.class);
                intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
                activity.startActivity(intent);
                activity.finish();
            }
        });
        ActionBar mActionBar = activity.getSupportActionBar();
        mActionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
        mActionBar.show();

then call this function with your icon and your text in your fragments onResume() method.
