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。
