How to change android tab text on the fly?

Question

This seems like it should be simple, but I can't figure out a way to do it. I'm needing a tab to have beginning text, but then have that text change after the user selects an item from a list. I know how to change tab backgrounds and colors via

mTabHost.getChildAt(index).setBackgroundColor();

but there isn't an option to change the tab's indicator. I've tried using an EditText.

private EditText tabName;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.statistics);

    comm = new Communicator();

    tabName = new EditText(this);
    tabName.setText("BeginningText");

    mTabHost = getTabHost();
    mTabHost.addTab(mTabHost
                   .newTabSpec("tab_1_stat")
                   .setIndicator(User)
                   .setContent(R.id.meStatsTab));
    mTabHost.addTab(mTabHost
                   .newTabSpec("tab_2_stat")
                   .setIndicator(tabName.getText())
                   .setContent(R.id.themStatsTab));
    mTabHost.addTab(mTabHost
                   .newTabSpec("tab_3_stat")
                   .setIndicator("Archive")
                   .setContent(R.id.archiveStatsTab));
    mTabHost.setOnTabChangedListener(this);
    getTabWidget().getChildAt(1).setOnClickListener(new onThemTabClicked());
    mTabHost.setCurrentTab(0);

    onTabChanged("tab_1_stat");

}

.....

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);

    tabName.setText("ChangedTabText");
    Bundle extras = intent.getExtras();
    themStats = extras.getStringArray("themStats");
    mTabHost.setCurrentTab(1);
    onTabChanged("tab_2_stat");
}

That didn't work either, along with a few other attempts. Any ideas? Thanks ahead of time!

Answer 1

TabWidget vTabs = .....;

// get desired tab view  
View vTab = vTabs.getChildAt(i);

// I guess vTab is instance of TextView
TextView vText = (TextView) vTab;

vText.setText(...);

Wow. Okay this was a pain. Apparently TabWidget does something funky with RelativeLayout and everytime I tried to do anything with radek-k's solution it was blowing up with a RelativeLayout error. So basically the work around is the following. It also allows you to change the font, font size, font color, etc.

TabWidget vTabs = getTabWidget();
RelativeLayout rLayout = (RelativeLayout) vTabs.getChildAt(tabIndex);
((TextView) rLayout.getChildAt(textIndex)).setText("NewTabText");

or in one line...

((TextView)((RelativeLayout)getTabWidget().getChildAt(tabIndex)).getChildAt(textIndex)).setText("NewTabText");

where "textIndex" is the index of the text field. In this case it is 1. If the tab has an icon or custom modifications the index could change.

Thanks again to radek-k. You definitely got me pointed in the right direction.
