Tab with scroll

Basically when we are using Tab-bar with number of tabs then all the tabs show in one screen not identify for particular tab click, can't scroll it.Here i implement  Tab-bar with horizontal scroll by using HorizontalScrollView in tab-host as show in XML file,In below code i added  tab as dynamically on button click.And easily control tabs.

public class MyTabActivity extends TabActivity {

private static int tabIx = 0;

private TabHost tabHost;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_tab);

tabHost = getTabHost();

addTab();

((Button) findViewById(R.id.add_tab))

.setOnClickListener(new OnClickListener() {

public void onClick(View v) {

tabIx++;

addTab();

}

});

}

private void addTab() {

LayoutInflater layoutInflate = LayoutInflater.from(MyTabActivity.this);

Button tabBtn = (Button) layoutInflate.inflate(R.layout.newtab_event, null);

tabBtn.setText("Tab " + tabIx);

Intent tabIntent = new Intent(TabActivity.this, NewActivity.class);

setupTab(tabBtn, tabIntent, "Tab " + tabIx);

}

protected void setupTab(View tabBtn, Intent setClass, String tag) {

TabSpec setContent = tabHost.newTabSpec(tag).setIndicator(tabBtn)

.setContent(setClass);

tabHost.addTab(setContent);

}

}
