Android高仿2048小游戏实现代码

刚开始进入splash界面：

1.splashactivity.java(两秒后进入开始界面，splash界面的布局只有一个图片，在博客后，会展示给大家看)

public class splashactivity extends activity {
@override
protected void oncreate(bundle savedinstancestate) {
super.oncreate(savedinstancestate);
setcontentview(r.layout.activity_splash);
new thread(new runnable() { 
@override
public void run() {
try {
thread.sleep(2000);
intent intent=new intent(splashactivity.this, loginactivity.class);
startactivity(intent);
} catch (interruptedexception e) {
// todo auto-generated catch block
e.printstacktrace();
}
finish();
}
}).start();
}
}

2.loginactivity（登陆界面）

private button btn1,btn2;
private edittext etacount,etpassword;
@override
protected void oncreate(bundle savedinstancestate) {
super.oncreate(savedinstancestate);
setcontentview(r.layout.activity_login);
initview();
}
private void initview() {
btn1=(button) findviewbyid(r.id.btn_login);
btn2=(button) findviewbyid(r.id.btn_register);
etacount=(edittext) findviewbyid(r.id.et_account);
etpassword=(edittext) findviewbyid(r.id.et_pwd);
btn1.setonclicklistener(new onclicklistener() {
//登录按钮的监听
@override
public void onclick(view v) {
sharedpreferences sharedpreferences=getsharedpreferences("user", mode_private);
string number=sharedpreferences.getstring("number", "");
int a,b;
if (number=="") {
a=0;//记录用户个数
}else {
a=integer.parseint(number);
}
string account;
string password;
for (b=0;b<a;b++) {
account="account"+b;
password="password"+b;
string jname=sharedpreferences.getstring(account,"");
string jpwd=sharedpreferences.getstring(password, "");
if (jname.equals(etacount.gettext().tostring())||jpwd.equals(etpassword.gettext().tostring())) {
if (jname.equals(etacount.gettext().tostring())&&jpwd.equals(etpassword.gettext().tostring())) {
finish();
intent intent=new intent(loginactivity.this, mainactivity.class);
startactivity(intent);
break;
}else if (jname.equals(etacount.gettext().tostring())) {
toast.maketext(loginactivity.this, "密码错误", toast.length_short).show(); 
}
}
}
if (b==a) {
toast.maketext(loginactivity.this, "用户未注册", toast.length_short).show();
}
}
});
//注册按钮的监听
btn2.setonclicklistener(new onclicklistener() {
@override
public void onclick(view v) {
string account;
string password;
sharedpreferences sharedpreferences=getsharedpreferences("user",mode_private);
string number=sharedpreferences.getstring("number", "");
int a;
int b;
if (number=="") {
a=0;
}else {
a=integer.parseint(number);
}
for (b = 0; b <a; b++) {
account="account"+b;
password="password"+b;
string jname=sharedpreferences.getstring(account,"");
if (jname.equals(etacount.gettext().tostring())) {
break;
}
}
if (b==a) {
if (etacount.gettext().tostring().equals("")&&etpassword.gettext().tostring().equals("")) {
toast.maketext(loginactivity.this,"用户名密码不能为空", toast.length_short).show();
}else {
account="account"+b;
password="password"+b;
a++;
sharedpreferences.editor editor=sharedpreferences.edit();
editor.putstring(account,etacount.gettext().tostring());
editor.putstring(password,etpassword.gettext().tostring());
editor.putstring("number",a+"");
editor.commit();
toast.maketext(loginactivity.this,"注册成功", toast.length_short).show();
}
}else {
toast.maketext(loginactivity.this,"该账户已存在", toast.length_short).show();
}
}
});
} 
}

loginactivity的布局如下：

<imageview
android:id="@+id/img_head"
android:layout_width="match_parent"
android:layout_height="260dp"
android:background="@drawable/head_game" />
<edittext 
android:id="@+id/et_account"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_below="@id/img_head"

android:hint="请输入账号" />
<edittext
android:id="@+id/et_pwd"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_below="@id/et_account"
android:layout_marginleft="50dp"
android:layout_margintop="10dp"
android:layout_marginright="50dp"
android:background="@drawable/set_charge_top"
android:drawableleft="@drawable/login_img3"
android:hint="请输入密码" />
<button 
android:id="@+id/btn_login"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="登录"
android:layout_below="@id/et_pwd"
android:layout_margintop="10dp"
android:layout_marginleft="70dp"/>
<button 
android:id="@+id/btn_register"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="注册"
android:layout_below="@id/et_pwd"
android:layout_torightof="@id/btn_login"
android:layout_margintop="10dp"
android:layout_marginleft="60dp"/>

3.mainactivity.java(主页面)

public class mainactivity extends activity {
private textview tvscore;
private animation animation;
private static mainactivity mainactivity = null;
private int score = 0;
private imageview imageview;
private gameview gameview;
public static mainactivity getmainactivity() {
return mainactivity;
}
public mainactivity() {
mainactivity = this;
}
@override
protected void oncreate(bundle savedinstancestate) {
super.oncreate(savedinstancestate);
setcontentview(r.layout.activity_main);
tvscore = (textview) findviewbyid(r.id.tvscore);
imageview=(imageview) findviewbyid(r.id.img_monkey);
}
public void onclick(view view) {
switch (view.getid()) {
case r.id.btn_help://帮助按钮，弹出对话框
animation=animationutils.loadanimation(this,r.anim.anim_monkey);
alertdialog.builder dialog2=new alertdialog.builder(this);
dialog2.settitle("嘲讽+藐视");
dialog2.setmessage("这么简单的游戏你还要帮助！！你咋不上天呢");
dialog2.setpositivebutton("给我绑个窜天猴", new onclicklistener() {
@override
public void onclick(dialoginterface dialog, int which) {
imageview.startanimation(animation);//为imageview设置动画
}
});
dialog2.setnegativebutton("继续玩~", new onclicklistener() {
@override
public void onclick(dialoginterface dialog, int which) {
}
});
dialog2.show();
break;
case r.id.btn_quit://退出按钮的点击事件
alertdialog.builder dialog = new alertdialog.builder(this);
dialog.settitle("提示：");
dialog.setmessage("主人，你真的要离开我么？");
dialog.setpositivebutton("确定", new onclicklistener() {
@override
public void onclick(dialoginterface dialog, int which) {
system.exit(0);
}
});
dialog.setnegativebutton("取消", new onclicklistener() {
@override
public void onclick(dialoginterface dialog, int which) {
}
});
dialog.show();
break;
default:
break;
}
}
public void clearscore() {//清除分数
score = 0;
showscore();
}
public void showscore() {//展示分数
tvscore.settext(score + "");
}
public void addscore(int s) {//添加分数
score += s;
showscore();
}
}

6.最后不要忘记在清单配置文件中配置信息

<?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="17"
android:targetsdkversion="21" />
<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"
//设置屏幕为竖屏
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>
</manifest>

7.其中的窜天猴的动画效果实现如下：

在res文件下新建一个anim文件夹
在anim文件夹下新建一个anim_monky.xml的布局文件

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="40"
android:fromydelta="0"
android:toydelta="-5000"
android:duration="4000"/>
<alpha 
android:fromalpha="1"
android:toalpha="0"
android:duration="5000"
/>
</set>

效果图如下：
