接通過ImageView建立一個全屏的圖片：

<?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="match_parent"    android:layout_height="match_parent"    android:src="@drawable/splash"    android:scaleType="center"    /></LinearLayout>

 建立activity：

package com.example.testwelcome;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.os.Handler;import android.widget.Toast;public class WelcomeActivity extends Activity{    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.welcome);        new Handler().postDelayed(new Runnable(){            @Override            public void run() {                // TODO Auto-generated method stub                Intent intent = new Intent(WelcomeActivity.this, MainActivity.class);                startActivity(intent);                WelcomeActivity.this.finish();                          }        }, 2000);//兩秒後跳轉到另一個頁面           }}

AndroidManifest.xml

設定預設啟動WelcomeActivity，並設定主題為全屏無標題樣式

    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >        <activity            android:name="com.example.testwelcome.WelcomeActivity"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>     <activity android:name="com.example.testwelcome.MainActivity"></activity>    </application>
