过年怎么可以不玩红包娱乐一下呢,微信里的摇骰子大小和石头剪刀布就是不错的游戏方式。

使用Java的Random函数很容易实现,以骰子为例:

1.骰子摇动的动画,使用animation-list帧动画实现
2.生成1~6的随机数,1 + new Random().nextInt(6)

以下是代码实现,文末提供图片资源下载:

package com.zms.dicedemo;  import java.util.Random;  import android.app.Activity; import android.graphics.drawable.Drawable; import android.os.Bundle; import android.os.Handler; import android.os.Message; import android.view.View; import android.widget.Button; import android.widget.ImageView; import android.widget.Toast;  public class MainActivity extends Activity {   private ImageView imageDice;  private Button btnGo;   @Override  protected void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.activity_main);   initialLayout();  }   private void initialLayout() {  imageDice = (ImageView) findViewById(R.id.imageDice);   btnGo = (Button) findViewById(R.id.btnGo);  btnGo.setOnClickListener(new MyOnClickListener());   }   class MyOnClickListener implements View.OnClickListener {   @Override  public void onClick(View v) {   switch (v.getId()) {   case R.id.btnGo:   imageDice.setImageDrawable(getResources().getDrawable(    R.drawable.anim_dice));   new Thread(new DiceThread()).start();   break;    default:   break;   }   }  }   public class DiceThread implements Runnable {   @Override  public void run() {   try {   Thread.sleep(2000);   } catch (InterruptedException e) {   e.printStackTrace();   }    Message messageDice = new Message();   messageDice.what = 1;   diceHandler.sendMessage(messageDice);   }   }   private void resetDiceImage() {  int randomInt = 1 + new Random().nextInt(6); // 1~6  Toast.makeText(MainActivity.this, getChineseByNumber(randomInt),   Toast.LENGTH_SHORT).show();  imageDice.setImageDrawable(getResources().getDrawable(   getResources().getIdentifier("dice_" + randomInt, "drawable",    getPackageName())));  }   private String getChineseByNumber(int number) {  switch (number) {  case 1:   return "一点小";   case 2:   return "二点小";   case 3:   return "三点小";   case 4:   return "四点大";   case 5:   return "五点大";   case 6:   return "六点大";   default:   return "";  }  }   final Handler diceHandler = new Handler() {   public void handleMessage(android.os.Message msg) {   switch (msg.what) {   case 1:   resetDiceImage();   break;    default:   break;   }  }   }; }
