package com.example.androidtablayout;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class AndroidActivity extends Activity {
// button to show progress dialog
Button btnCallTabActivity;
Context con;
public static final int progress_bar_type = 0;
// File url to download
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mains);
con=this;
// show progress bar button
btnCallTabActivity = (Button) findViewById(R.id.btnTabActivity);
// Image view to show image after downloading
/**
* Show Progress bar click event
* */
btnCallTabActivity.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(con, AndroidTabLayoutActivity.class);
startActivity(i);
}
});
}
/**
* Showing Dialog
* */
}
And your Tab Activity should be like this
package com.example.androidtablayout;
import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class AndroidTabLayoutActivity extends TabActivity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost tabHost = getTabHost();
// Tab for Photos
TabSpec photospec = tabHost.newTabSpec("Photos");
photospec.setIndicator("Photos", getResources().getDrawable(R.drawable.icon_photos_tab));
Intent photosIntent = new Intent(this, PhotosActivity.class);
photospec.setContent(photosIntent);
// Tab for Songs
TabSpec songspec = tabHost.newTabSpec("Songs");
// setting Title and Icon for the Tab
songspec.setIndicator("Songs", getResources().getDrawable(R.drawable.icon_songs_tab));
Intent songsIntent = new Intent(this, SongsActivity.class);
songspec.setContent(songsIntent);
// Tab for Videos
TabSpec videospec = tabHost.newTabSpec("Videos");
videospec.setIndicator("Videos", getResources().getDrawable(R.drawable.icon_videos_tab));
Intent videosIntent = new Intent(this, VideosActivity.class);
videospec.setContent(videosIntent);
// Adding all TabSpec to TabHost
tabHost.addTab(photospec); // Adding photos tab
tabHost.addTab(songspec); // Adding songs tab
tabHost.addTab(videospec); // Adding videos tab
}
}

I edit my manifest.xml and added that lines:
<activity android:name="tcc.sigme.TabBar" >
</activity>
<activity android:name="tcc.sigme.Tab01" >
</activity>
<activity android:name="tcc.sigme.Tab02" >
</activity>
<activity android:name="tcc.sigme.Tab03" >
</activity>
you see in : https://github.com/EdilsonGalvao/SigMe/blob/master/SigME/AndroidManifest.xml
