    一个很简单的例子：程序启动界面
 
主要code：
package com.ssx.startload;
 
<br>import android.app.activity;<br>import android.content.intent;<br>import android.os.bundle;<br>import android.os.handler;<br>import android.os.message;<br>import android.view.window;<br>import android.view.windowmanager;
public class startloadactivity extends activity {<br> /** called when the activity is first created. */<br>  public static final int continue = 0x108;<br>  public static final int update = 0x109;<br>  final handler handler = new handler() {<br>   @override<br>   public void handlemessage(message msg) {
    switch (msg.what) {<br>    case startloadactivity.continue:
     intent it = new intent();<br>     it.setclass(startloadactivity.this, mainactivity.class);<br>     startactivity(it);<br>     finish();<br>     break;<br>    }<br>    super.handlemessage(msg);<br>   }
  };
  @override<br>  public void oncreate(bundle savedinstancestate) {<br>   super.oncreate(savedinstancestate);<br>   getwindow().setflags(windowmanager.layoutparams.flag_fullscreen,<br>     windowmanager.layoutparams.flag_fullscreen);<br>   requestwindowfeature(window.feature_no_title);<br>   setcontentview(r.layout.start_loading);<br>   //handler.sendemptymessage(startloadingactivity.continue);<br>  thread sleepthread = new thread() {<br>    public void run() {
     try {<br>      thread.sleep(5000);//设置启动欢迎界面时间<br>      intent it = new intent();<br>      it.setclass(startloadactivity.this, mainactivity.class);<br>      startactivity(it);<br>      handler.sendemptymessage(startloadactivity.continue);<br>     } catch (interruptedexception e) {<br>      // todo auto-generated catch block<br>      e.printstacktrace();<br>      handler.sendemptymessage(startloadactivity.continue);<br>     }<br>    }<br>   };<br>   sleepthread.start();<br>  }<br> }
