Question

I make three tabs.

Language.( Include language Class with language layout)
Activation ( Include Activation Class with activate layout)
Settings ( Include Settings Class with setting layout)

In the settings list if i change the setting to hide the words definition in the language layout.
And than again click on the tab language words translation still there.

I think i have to apply here on tab change listner.

But what should i do in on tab change listner.

that is my TabActivity.

 package com.languagetranslate;

import com.languagetranslate.Constants.Constants;
import com.languagetranslate.dao.UserData;

import android.app.Activity;
import android.app.TabActivity;

import android.view.View;
import android.widget.FrameLayout;
import android.widget.ListView;
import android.widget.RelativeLayout;
import android.widget.TabHost;
import android.widget.TextView;
import android.widget.TabHost.OnTabChangeListener;

public class Screen1 extends TabActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.screen1);

        initializeTabs();
    }

    private void initializeTabs() {
        TabHost tabHost = getTabHost(); // The activity TabHost
        TabHost.TabSpec spec; // Resusable TabSpec for each tab
        Intent intent; // Reusable Intent for each tab

        // Create an Intent to launch an Activity for the tab (to be reused)
        intent = new Intent().setClass(this, WordsClass.class);

        // Initialize a TabSpec for each tab and add it to the TabHost
        spec = tabHost.newTabSpec("Words").setIndicator("Words")
                .setContent(intent);
        tabHost.addTab(spec);

        // Do the same for the other tabs
        intent = new Intent().setClass(this, ActivateClass.class);
        spec = tabHost.newTabSpec("Activitation").setIndicator("Activitation")
                .setContent(intent);
        tabHost.addTab(spec);

        // Do the same for the other tabs
        intent = new Intent().setClass(this, Settings.class);
        spec = tabHost.newTabSpec("Settings").setIndicator(".\n.\n.")
                .setContent(intent);
        tabHost.addTab(spec);

        tabHost.setCurrentTab(2);


        tabHost.setOnTabChangedListener(new OnTabChangeListener() {

            public void onTabChanged(String tabId) {

                if ( tabId == "Language" ){

                    Constants.TAGS_ENABLE = UserData.getTagSettings(getApplicationContext(),
                            Constants.SETTINGS_FILE);
                    if (Constants.TAGS_ENABLE == true) {
                        LayoutInflater inflate = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                        FrameLayout item = (FrameLayout)findViewById(android.R.id.tabcontent);
                        View child = inflate.inflate(R.layout.wordlayout, null);
                            child.findViewById(R.id.availabletags).setVisibility(View.VISIBLE);
                            child.findViewById(R.id.tags).setVisibility(View.VISIBLE);

                            item.addView(child);
//                      
//                      ((TextView) findViewById(R.id.availabletags))
//                              .setVisibility(View.VISIBLE);
//                      ((ListView) findViewById(R.id.tags))
//                              .setVisibility(View.VISIBLE);

                    }

                }


            }
        });
    }
}

maybe you can put those in Language’s onResume():

@Override
protected void onResume()
{
    super.onResume();
    if (Constants.TAGS_ENABLE == true) {
        // set visibility...
    }
}
