Android：简单的开场界面

接通过ImageView创建一个全屏的图片：

<?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>

新建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);//两秒后跳转到另一个页面
       
    }

}

AndroidManifest.xml

设置默认启动WelcomeActivity，并设置主题为全屏无标题样式

    <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>
