Android Programming Simple Start screen implementation method _android

This article describes the Android simple Start screen implementation method. Share to everyone for your reference, specific as follows:

After each Android application starts, a splash boot interface appears, showing the product logo, company logo, or developer information. If the application startup time is longer, then the start interface is a good thing to allow users to patiently wait for this boring time, improve the user experience.

1. Splash.xml Layout file

<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 "
  tools:context= ". Splashactivity ">
  <imageview
    android:layout_width=" match_parent "
    android:layout_height=" match _parent "
    android:background=" @drawable/welcome_android "
    android:scaletype=" Fitcenter "/>
</ Relativelayout>

2. Splashactivity class, using the handler postdelayed method, 3 seconds to jump to the main view

Package Cn.eoe.leigo.splash;
Import android.app.Activity;
Import android.content.Intent;
Import Android.os.Bundle;
Import Android.os.Handler; /** * * @{#} splashactivity.java Create on 2013-5-2 pm 9:10:01 * Class desc: Splash Screen * * <p>copyright:copyrigh T (c) 2013 </p> * @Version 1.0 * @Author <a href= "mailto:gaolei_xj@163.com" >Leo</a> * * */PUBLIC CL
  Ass Splashactivity extends Activity {//Latency 3 sec private static final long Splash_delay_millis = 3000;
    @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
    Setcontentview (R.layout.splash);
        Using the Handler postdelayed method, perform a jump to mainactivity new Handler () after 3 seconds. postdelayed (New Runnable () {public void run () {
      GoHome ();
  }}, Splash_delay_millis);
    } private void GoHome () {Intent Intent = new Intent (splashactivity.this, Mainactivity.class);
    SplashActivity.this.startActivity (Intent);
  SplashActivity.this.finish ();}
}

 

3. Configure Androidmanifest.xml

<?xml version= "1.0" encoding= "Utf-8"?> <manifest xmlns:android= "http://schemas.android.com/apk/res/" Android "package=" Cn.eoe.leigo.splash "android:versioncode=" 1 "android:versionname=" 1.0 "> <uses-sdk and roid:minsdkversion= "android:targetsdkversion="/> <application android:icon= "@drawable/logo" Droid:label= "@string/app_name" > <activity android:name= ". Splashactivity "android:configchanges=" Keyboardhidden "android:label=" @string/app_name "Android:launchmo De= "Singletask" android:screenorientation= "Portrait" Android:theme= "@android: Style/theme.notitlebar.fullscreen  "> <intent-filter> <action android:name=" Android.intent.action.MAIN "/> <category  Android:name= "Android.intent.category.LAUNCHER"/> </intent-filter> </activity> <activity Android:name= ".

 Mainactivity "/> </application>
