tabhost reload while screen orientation change

Question

I use tabhost as my main activity. And show the first list in initial. And onclick to the second list. At this time, the screen orientation change, the screen is change to initial list. How to resolve it? I already try below: 1. add android:configChanges="orientation|keyboardHidden" android:screenOrientation="portrait" in Manifest 2. add onConfigurationChanged in each activity

@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
}

Is there any other solution?

Sorry~ I means the content in tabcontent(FrameLayout). And the tabs(TabWidget) didn't reload when the screen change.

On create, call AActivity to show list1. And in AActivity listonclick, I make it call BActivity to show list2. But when screen change, the tabcontent call AActivity and show list1.

If I understand correctly, you need to save which Tab is selected. You could try something like this...

public class MyTabActivity extends TabActivity
    implements TabHost.onTabChangeListener {

    private int currentTab = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        getTabHost().setOnTabChangedListener(this);
    }

    @Override
    protected void onResume() {
        ...
        currentTab = getSharedPreferences("myapp", MODE_PRIVATE).getInt("currentTab", 0);
        getTabHost().setCurrentTab(currentTab);
    }

    @Override
    protected void onPause() {
        ...
        getSharedPreferences("myapp", MODE_PRIVATE).edit().putInt("currentTab", currentTab).commit();
    }

    @Override
    public void onTabChanged(String tabId) {
        currentTab = getTabHost().getCurrentTab();
    }
}
