Android基于API的Tabs3实现仿优酷tabhost效果实例

本文实例讲述了android基于api的tabs3实现仿优酷tabhost效果。分享给大家供大家参考，具体如下：

前两天老师就让自己写个视频播放器客户端，这个是他上课讲的一个小小demo,通过查看安卓api的tabs3，实现仿优酷视频客户端的tabhost效果。我的api路径是d:\android\sdk\samples\android-17\apidemos\src\com\example\android\apis\view下的tabs3，下面是实现效果：

废话不多说了，直接上码：

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);
    //获取对象
    tabhost = gettabhost();
    tabhost.addtab(tabhost.newtabspec("myself")
        .setindicator("个人中心")
        .setcontent(new intent(this, myselfactivity.class)));
    tabhost.addtab(tabhost.newtabspec("myindex")
        .setindicator("优酷首页")
        .setcontent(new intent(this, myindexactivity.class)));
    tabhost.addtab(tabhost.newtabspec("mycenter")
        .setindicator("频道中心")
        .setcontent(new intent(this, mycenteractivity.class)));
    //指定的当前的tab
    //通过索引指定 索引从0开始
    tabhost.setcurrenttab(0); //从零开始
    //通过标识来激活
   // tabhost.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);
  }
}

下面是布局文件：

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="优酷中心" />
</relativelayout>

activity_myindex.xml

<textview
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="优酷首页" />

activity_myself.xml

<textview
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="个人首页" />

当然别忘了在清单文件中配置activity

<!-- 配置activity组件 -->
<activity android:name="com.example.video.myindexactivity"/>
<activity android:name="com.example.video.myselfactivity"/>
<activity android:name="com.example.video.mycenteractivity"/>

希望本文所述对大家android程序设计有所帮助。
