setCurrentTab Android
- by Ali
i have 4 tabs on my main screen,
main ( set to current ) , Call, Email, Web
When a user clicks on any of tab call, email or web, it starts making a call, or go to compose a email, or opens up the browser respectfully.
Problem is, i want just three tabs (Call, Email, Web) and i Dont want any tab to be selected by default, means they should only become active when a user Touch them..(a call or any service cant be main at all)
All java coding, XML file, and Manifest code is given below,
XML File (tab_activity_layout)
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"

android:layout_height="fill_parent">

</RelativeLayout>
</LinearLayout>
</TabHost>
Java Coding (MainTabActivity)
package com.NVT.android;
import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TabHost;
public class MainTabActivity extends TabActivity{
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_activity_layout);
Resources res = getResources(); // Resource object to get Drawables
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, Main.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("main").setIndicator("Main",
res.getDrawable(R.drawable.ic_tab_artists_grey))
.setContent(intent);
tabHost.addTab(spec);
TabHost host=getTabHost();
host.addTab(host.newTabSpec("one")
.setIndicator("Call")
.setContent(new Intent(this, CallService.class)));
host.addTab(host.newTabSpec("two")
.setIndicator("Email")
.setContent(new Intent(this, EmailService.class)));
host.addTab(host.newTabSpec("three")
.setIndicator("Web")
.setContent(new Intent(this, WebService.class)));
}
