Related Android TabHost Questions & Answers:

How do I change the background of an Android tab widget? 
1:	 public static void setTabColor(TabHost tabhost) {
2:	    for(int i=0;i<tabhost.getTabWidget().getChildCount();i++)
3:	    {

This will set your tab colors:

public static void setTabColor(TabHost tabhost) {
    for(int i=0;i<tabhost.getTabWidget().getChildCount();i++) {
        tabhost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#FF0000")); //unselected
    }
    tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab()).setBackgroundColor(Color.parseColor("#0000FF")); // selected
}

and if you put it within the onTabChangedListener(), it will keep the correct color for selected tabs.

Android: Change Tab Text Color Programmatically 
1:	 TabHost tabhost = getTabHost();
2:	    for(int i=0;i<tabhost.getTabWidget().getChildCount();i++) 
3:	    {

To change the text color of tabs, you need to get the view i.e TextView which is set as title of tabs and you can change it like this:

    TabHost tabhost = getTabHost();
    for(int i=0;i<tabhost.getTabWidget().getChildCount();i++) 
    {
        TextView tv = (TextView) tabhost.getTabWidget().getChildAt(i).findViewById(android.R.id.title);
        tv.setTextColor(.....);
    }

hope this helps....

TabWidget current tab bottom line color 
1:	 TabHost host = (TabHost)view.findViewById(R.id.tab_host);
2:	TabWidget widget = host.getTabWidget();
3:	for(int i = 0; i < widget.getChildCount(); i++) {
-
1:	 TabHost host = (TabHost)view.findViewById(R.id.tab_host);
2:	TabWidget widget = host.getTabWidget();
3:	for(int i = 0; i < widget.getChildCount(); i++) {

The color of the tab indicator is being set by a selector drawable which can be found here and looks like this:

<!-- AOSP copyright notice can be found at the above link -->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Non focused states -->
    <item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_holo" />
    <item android:state_focused="false" android:state_selected="true"  android:state_pressed="false" android:drawable="@drawable/tab_selected_holo" />

    <!-- Focused states -->
    <item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_focused_holo" />
    <item android:state_focused="true" android:state_selected="true"  android:state_pressed="false" android:drawable="@drawable/tab_selected_focused_holo" />

    <!-- Pressed -->
    <!--    Non focused states -->
    <item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_holo" />
    <item android:state_focused="false" android:state_selected="true"  android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_holo" />

    <!--    Focused states -->
    <item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_holo" />
    <item android:state_focused="true" android:state_selected="true"  android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_holo" />
</selector>

The drawables that the selector uses are all colored in that light blue. You can replace those drawables with your own recolored versions. The originals look like this (originals are small, links included):

You'll want to copy the above selector into your own project along with the drawables. Then you'll want to recolor the drawables to whatever color you want them to be. Then you'll want to set your selector as the background for your tab indicators. You can do that like this (after setting up your tabs):

TabHost host = (TabHost)view.findViewById(R.id.tab_host);
TabWidget widget = host.getTabWidget();
for(int i = 0; i < widget.getChildCount(); i++) {
    View v = widget.getChildAt(i);

    // Look for the title view to ensure this is an indicator and not a divider.
    TextView tv = (TextView)v.findViewById(android.R.id.title);
    if(tv == null) {
        continue;
    }
    v.setBackgroundResource(R.drawable.your_tab_selector_drawable);
}

There might be an easier way to do this by setting your own customer indicator layout with a background selector but this is what worked easiest for me.

TabHost on Android crashes the app 
1:	 TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost);
-
1:	 TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost);

The problem seems to be with the naming of your TabHost. You named it:

android:id="@+id/tabHost"

But when you create you Activity file, you're looking for:

TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost);

Which is not the same as you have. Your TabHost should be named this way:

android:id="@android:id/tabhost"

How to use Bottom tabActivity in my Activity itself 
1:	 public class GinfyActivity extends Activity
2:	TabHost mTabHost = (TabHost)findViewById(android.R.id.tabhost);
-
1:	 public class GinfyActivity extends Activity
2:	TabHost mTabHost = (TabHost)findViewById(android.R.id.tabhost);

replace these two lines

public class GinfyActivity extends Activity
TabHost mTabHost = (TabHost)findViewById(android.R.id.tabhost);

with following

public class GinfyActivity extends TabActivity
TabHost mTabHost = getTabHost();

EDIT

change activity which you want to display in following line.

Intent intentAndroid = new Intent().setClass(this, Your_Activity.class);

And if you want only Tab then it's better to use ActionBar as TabHost is deprecated.

Full Example of TabHost

To use ActionBar here is sample code (use Sherlock or appcompat Library for < API 11)

public class MainActivity extends Activity implements TabListener {
ActionBar actionBar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    actionBar=getActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    actionBar.addTab(actionBar.newTab().setText("TAB 1").setTabListener(this));
    actionBar.addTab(actionBar.newTab().setText("TAB 2").setTabListener(this));
    actionBar.addTab(actionBar.newTab().setText("TAB 3").setTabListener(this));
}

@Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
    // TODO Auto-generated method stub

}

@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
    switch (tab.getPosition()) {
    case 0:
        //start activity here or toast
        Toast.makeText(getApplicationContext(), "Start First Activity", Toast.LENGTH_SHORT).show();
        break;
    case 1:
        //start activity here or toast
        Toast.makeText(getApplicationContext(), "Start Second Activity", Toast.LENGTH_SHORT).show();
        break;
    case 2:
        //start activity here or toast
        Toast.makeText(getApplicationContext(), "Start Third Activity", Toast.LENGTH_SHORT).show();
        break;

    default:
        break;
    }

}

@Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
    // TODO Auto-generated method stub

}

 }
