Welcome screen and App icon

This project uses Android Studio 3.0.1 as a development tool


Created a activity_splash.xml layout file for the Welcome interface layout, first modified to Relativelayout layout

<?xml version="1.0" encoding="utf-8"?><!--添加一张欢迎界面的背景--><RelativeLayout    xmlns:android=""    android:layout_width = "match_parent"    android:layout_height="match_parent"    android:background="@drawable/launch_bg">    <!--显示版本号-->    <TextView        android:id="@+id/tv_version"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:textColor="@android:color/white"        android:textSize="14sp"        android:layout_centerInParent="true"/></RelativeLayout>

Create class, welcome interface implementation Class

Package;import Android.content.intent;import;import;import; Import Android.os.bundle;import;import Android.widget.textview;import Java.util.timer;import Java.util.timertask;public class Splashactivity extends appcompatactivity{@Override protecte        d void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);        Setcontentview (R.layout.activity_splash);        Set this interface for//vertical screen setrequestedorientation (activityinfo.screen_orientation_portrait);    Init ();        } private void Init () {TextView tv_version = Findviewbyid (;            try {packageinfo packageinfo = Getpackagemanager (). Getpackageinfo (Getpackagename (), 0);        Tv_version.settext ("version:" +packageinfo.versionname); } catch (Packagemanager.namenotfoundexception E) {e.printstacktrace ();        Tv_version.settext ("version");        }//Using a timer to allow this interface to jump after 3 seconds, the timer has a thread that continuously executes the task Timer timer = new timer (); TimerTask timertask = new TimerTask () {@Override public void run () {//Send intent Implement page jump                Turn, the first parameter is the context of the current page, the second parameter is the home page to jump Intent Intent = new Intent (splashactivity.this,mainactivity.class);                StartActivity (Intent);            After jumping off the current Welcome page SplashActivity.this.finish ();        }        };    Schedule execution TimerTask, second parameter incoming delay time (MS) Timer.schedule (timertask,3000); }}

Configure the Welcome interface in the manifest file Androidmanifest.xml, modify the application portal to the Welcome screen, and then remove the ActionBar effect

<?xml version= "1.0" encoding= "Utf-8"? ><manifest xmlns:android= " Android "package=" "> <!--originally android:theme=" @style/apptheme "-< !--Remove Actionbar title bar-<!--add app icon,app_icon--> <application android:allowbackup= "true" Androi        d:icon= "@drawable/app_icon" android:label= "@string/app_name" android:roundicon= "@mipmap/ic_launcher_round" Android:supportsrtl= "true" android:theme= "@style/theme.appcompat.noactionbar" > <activity Android : Name= ". Splashactivity "> <intent-filter> <action android:name=" Android.intent.action.MAIN "/        > <category android:name= "Android.intent.category.LAUNCHER"/> </intent-filter> </activity> <!--Add implementing Class--<activity android:name= ". Mainactivity "></activity> </application></manifEst>
