Question

How can I get reference to the TextViews, for example, if I didn’t set layout as a content view?

I’m using TabHost to switch between Activities:

public class TimerResultsActivity extends TabActivity {

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

        TextView resultsText = (TextView)findViewById(R.id.textView1);
        resultsText.setText("test");
    }

...

“textView1” has added to one of tabs, but hasn’t declared in the main.xml.
How can I change a text on it?

Answer 1

You’ll need a reference to the base of the layout that it is declared in. Then you can use the findViewById() method of the ViewGroup it belongs to.

TextView resultsText = (TextView)myTab.findViewById(R.id.textView1);
