The tabs at the bottom stop working once I click on the second tab.
Could anyone please help?
Here is some code.
// Main Activity
public class MainTabActivity extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/** TabHost will have Tabs */
TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost);
/** TabSpec used to create a new tab.
* By using TabSpec only we can able to setContent to the tab.
* By using TabSpec setIndicator() we can set name to tab. */
/** tid1 is firstTabSpec Id. Its used to access outside. */
TabSpec firstTabSpec = tabHost.newTabSpec("tid1");
TabSpec secondTabSpec = tabHost.newTabSpec("tid1");
/** TabSpec setIndicator() is used to set name for the tab. */
/** TabSpec setContent() is used to set content for a particular
tab. */
firstTabSpec.setIndicator("View Map").setContent(new
Intent(this,FirstTab.class));
secondTabSpec.setIndicator("Route Information").setContent(new
Intent(this,SecondTab.class));
/** Add tabSpec to the TabHost to display. */
tabHost.addTab(firstTabSpec);
tabHost.addTab(secondTabSpec);
}
}
// First Tab Activity
public class FirstTab extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/* First Tab Content */
TextView textView = new TextView(this);
textView.setText("First Tab");
setContentView(textView);
}
}
// Second Tab Activity with ListView
public class SecondTab extends ListActivity{
/** Called when the activity is first created. */
static final String[] stops = new String[] {
"Odegard", "Memorial Union"};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(this,
R.layout.second_tab_layout, stops));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View
view,
int position, long id) {
// When clicked, show a toast with the TextView
text
Toast.makeText(getApplicationContext(),
((TextView)
view).getText(),
Toast.LENGTH_SHORT).show();
}
});
}
// Second tab activity xml layout file
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android";
