I have created tab app.. now I am playing with screen rotation. I tried to set tabHost.getTabWidget().setCurrentTab(1)
, which should show second tab (first is 0). The point is that second tab is shown as selected, but shown content is from first tab... How can I solve that?
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
myCommunicator = new Communicator();
dbAdapter = new ToDoDBAdapter(this);
if (getLastNonConfigurationInstance() != null)
{
CurrentTab = (Integer)getLastNonConfigurationInstance();
createView();
}
else
{
BuildDialog = ProgressDialog.show(this, "Loading", "Updating data...", true, false);
BuildDialog.show();
new LoadChannels().execute();
}
}
private void createView()
{
tabHost = (TabHost)findViewById(android.R.id.tabhost);
tabHost.setOnTabChangedListener(this);
Intent intent;
TabSpec spec;
intent = new Intent().setClass(this, Channels.class);
// TAB 1
spec = tabHost.newTabSpec("kanali").setIndicator("Kanali",getResources().getDrawable(R.drawable.menu_channels)).setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, Currently.class);
// TAB 2
spec = tabHost.newTabSpec("trenutno").setIndicator("Trenutno",getResources().getDrawable(R.drawable.menu_current)).setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, Reminders.class);
// TAB 3
spec = tabHost.newTabSpec("opomniki").setIndicator("Opomniki",getResources().getDrawable(R.drawable.menu_reminder)).setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, About.class);
// TAB 4
spec = tabHost.newTabSpec("oprogramu").setIndicator("O programu",getResources().getDrawable(R.drawable.menu_about)).setContent(intent);
tabHost.addTab(spec);
tabHost.setBackgroundColor(Color.WHITE);
tabHost.setCurrentTab(1); // Should always set content to second
}
@Override public Object onRetainNonConfigurationInstance() { return CurrentTab; }
@Override
public void onTabChanged(String tabId) {
CurrentTab = tabHost.getCurrentTab();
}
public void onDestroy() {
super.onDestroy();
// Close the database
try {
dbAdapter.close();
} catch (Exception e) {
// TODO: handle exception
}
}
@Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
setContentView(R.layout.main);
createView();
}
Why are you calling getTabWidget()
? You should use the setCurrentTab()
on the tabHost
itself.
Works fine here.
tabHost.setCurrentTab(1);
