Android High imitation 2048 small game implementation code _android

Just started into the splash interface:

1.splashactivity.java (two seconds after entering the start interface, splash interface layout Only a picture, after the blog, will show you)

public class Splashactivity extends activity {

Setcontentview (R.layout.activity_splash);
New Thread (New Runnable () { 
@Override public

try {
thread.sleep);
Intent intent=new Intent (Splashactivity.this, loginactivity.class);
StartActivity (intent);
} catch (Interruptedexception e) {
//TODO auto-generated catch block
e.printstacktrace ();
}
Finish ();
}
}). Start ();
}

6. Finally, do not forget to configure information in the manifest configuration file

<?xml version= "1.0" encoding= "Utf-8"?> <manifest xmlns:android= "http://schemas.android.com/apk/res/" Android "package=" com.jerry.game2048 "android:versioncode=" 1 "android:versionname=" 1.0 "> <uses-sdk android: minsdkversion= "android:targetsdkversion="/> <application android:allowbackup= "true" android:icon= "@ drawable/game2048 "android:label=" @string/app_name "android:theme=" @style/apptheme "> <activity android:name= "Com.jerry.game2048.MainActivity" android:label= "@string/app_name"//Set screen to vertical screen android:screenorientation= "Portrait" > </activity> <activity android:name= ". Splashactivity "android:label=" @string/title_activity_splash "> <intent-filter> <action android:name=" Android.intent.action.MAIN "/> <category android:name=" Android.intent.category.LAUNCHER "/> </ intent-filter> </activity> <activity android:name= ". Loginactivity "android:label=" @string/title_activity_login "> </activity> </application&Gt </manifest>

7. One of the monkey's animation effects achieved as follows:

Create a new Anim folder under the Res file
Create a new Anim_monky.xml layout file under the Anim folder

Anim_monky.xml

<?xml version= "1.0" encoding= "Utf-8"?> <set xmlns:android=
"http://schemas.android.com/apk/res/" Android ">
<translate
android:fromxdelta=" 0 "
android:toxdelta=" Android:fromydelta= "
0"
android:toydelta= " -5000"
android:duration= "4000"/>
<alpha android:fromalpha= 
"1"
Android:toalpha= "0"
android:duration= "5000"
/>
</set>

The effect chart is as follows:

The above is a small set to introduce Android 2048 small game to achieve code, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone. Here also thank you very much for the cloud Habitat Community website support!
