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:layout_marginLeft="50dp"
android:layout_marginRight="50dp"
android:layout_marginTop="40dp"
android:background="@drawable/set_charge_top"
android:drawableLeft="@drawable/login_img2"
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();
}
}

}
//根据卡片宽和高
@Override

//该方法就是宽高发生改变的时候我们可以得到当前的宽高是多少 
//该方法也是在游戏一被创建的时候就调用，也就是用来初始宽高的方法

//获取手机较窄的长度，-10是用来间隔每个卡片的距离，用手机的宽除以4就是每个卡片的长度了

}
}

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：
