Android API based TABS3 to implement Tabhost effect example _android

This article describes the Android API based TABS3 to achieve the tabhost effect. Share to everyone for your reference, specific as follows:

Two days ago, the teacher let himself write a video player client, this is his lectures on a small demo, by looking at the TABS3 of the Android API to achieve the tabhost effect of imitation cool video client. My API path is the TABS3 under D:\android\sdk\samples\android-17\ApiDemos\src\com\example\android\apis\view, and here is the implementation effect:

Nonsense not much said, directly on the code:

Mainactivity.java

Package com.example.video;
Import Android.os.Bundle; Import Android.
R.layout;
Import android.app.Activity;
Import android.app.TabActivity;
Import android.content.Intent;
Import Android.view.LayoutInflater;
Import Android.view.Menu;
Import Android.widget.TabHost;
  public class Mainactivity extends tabactivity {public tabhost tabhost;
    @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
    Gets the object tabhost = Gettabhost (); Tabhost.addtab (Tabhost.newtabspec ("Myself"). Setindicator ("Personal Center"). SetContent (New Intent (This, myselfactiv
    Ity.class))); Tabhost.addtab (Tabhost.newtabspec ("Myindex"). Setindicator ("Youku Home"). SetContent (New Intent (This, myindexact
    Ivity.class))); Tabhost.addtab (Tabhost.newtabspec ("Mycenter"). Setindicator ("Channel Center"). SetContent (New Intent (This, Mycentera
    Ctivity.class))); Specifies that the current tab//is Tabhost.setcurrenttab (0) with index-specified index starting from 0;
   Start from zero//Activate by identityTabhost.setcurrenttabbytag ("XXX1");  @Override public boolean Oncreateoptionsmenu (Menu menu) {//Inflate the menu; This adds items to the action Bar
    If it is present.
    Getmenuinflater (). Inflate (R.menu.main, menu);
  return true;

 }
}

Mycenteractivity.java

Package com.example.video;
Import android.app.Activity;
Import Android.os.Bundle;
public class Mycenteractivity extends activity{
  @Override
  protected void onCreate (Bundle savedinstancestate) {
    super.oncreate (savedinstancestate);
    Setcontentview (R.layout.activity_mycenter);
  }

Myindexactivity.java

Package com.example.video;
Import android.app.Activity;
Import Android.os.Bundle;
public class Myindexactivity extends activity{
  @Override
  protected void onCreate (Bundle savedinstancestate) {
    super.oncreate (savedinstancestate);
    Setcontentview (R.layout.activity_myindex);
  }

Myselfactivity.java

Package com.example.video;
Import android.app.Activity;
Import Android.os.Bundle;
public class Myselfactivity extends activity{
  @Override
  protected void onCreate (Bundle savedinstancestate) {
    super.oncreate (savedinstancestate);
    Setcontentview (r.layout.activity_myself);
  }

The following is a layout file:

Activity_mycenter.xml

<relativelayout xmlns:android= "http://schemas.android.com/apk/res/android"
  xmlns:tools= "http:// Schemas.android.com/tools "
  android:layout_width=" match_parent "
  android:layout_height=" Match_parent "
  android:paddingbottom= "@dimen/activity_vertical_margin"
  android:paddingleft= "@dimen/activity_ Horizontal_margin "
  android:paddingright=" @dimen/activity_horizontal_margin "
  android:paddingtop=" @dimen /activity_vertical_margin "
  tools:context=". Mainactivity ">
  <textview
    android:layout_width=" wrap_content "
    android:layout_height=" Wrap_ Content "
    android:text= Center"/>
</RelativeLayout>

Activity_myindex.xml

<textview
  android:layout_width= "wrap_content"
  android:layout_height= "Wrap_content"
  android: text= "Youku Home"/>

Activity_myself.xml

<textview
    android:layout_width= "wrap_content"
    android:layout_height= "wrap_content"
    android:text = "Personal Home"/>

Of course, don't forget to configure the activity in the manifest file

<!--Configure activity Components-->
<activity android:name= "com.example.video.MyIndexActivity"/>
< Activity android:name= "com.example.video.MySelfActivity"/>
<activity android:name= " Com.example.video.MyCenterActivity "/>

I hope this article will help you with the Android program.
