android--欢迎界面

欢迎界面的操作创建两个Activity：MainActivity和ActivityDemo

代码如下：

package com.example.helloword;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.view.Menu;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Handler x = new Handler() ;
        x.postDelayed(new splashhandler(), 3000) ;
    }
    class splashhandler implements Runnable{

		@Override
		public void run() {
			startActivity(new Intent(MainActivity.this,Activitydemo.class)) ;
			MainActivity.this.finish() ;
			
		}
    	
    }
    @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;
    }
    
}

main.xml代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >  
  <ImageView 
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:src="@drawable/welcome_logo"
      android:scaleType="fitCenter"
      android:id="@+id/wordpress_logo"/>

</LinearLayout>
