Android使用Handler实现打地鼠游戏

本文实例为大家分享了Android使用Handler实现打地鼠的具体代码，供大家参考，具体内容如下

1.实现效果

如下图所示：

2.代码实现

新建一个名为DiglettDemo的项目，activity_main.xml代码如下：

<?xml version="1.0" encoding="utf-8"?>

MainActivity.class代码如下：

public class MainActivity extends AppCompatActivity implements View.OnClickListener, View.OnTouchListener {  public static final int CODE = 999;  public static final int RANDOM_NUMBER = 500;  private TextView mTextView;  private Button mButton;  private ImageView mImageView;  /**   * 定义地鼠的位置   */  public int[][] mPosition = new int[][]{      {342, 180}, {432, 880}, {521, 256}, {429, 780},      {456, 976}, {145, 665}, {123, 678}, {564, 567},  };  private int mTotalCount, mSuccessCount = 0;  public static final int MAX_COUNT = 10;  private MyHandler mMyHandler = new MyHandler(this);  @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    initView();  }  private void initView() {    mTextView = findViewById(R.id.textView);    mButton = findViewById(R.id.button);    mImageView = findViewById(R.id.imageView);    mButton.setOnClickListener(this);    mImageView.setOnTouchListener(this);  }  @Override  public void onClick(View v) {    switch (v.getId()) {      case R.id.button:        start();        break;    }  }  private void start() {    mTextView.setText("游戏开始了！");    mButton.setText("游戏中...");    mButton.setEnabled(false);    //发送消息    next(RANDOM_NUMBER);  }  private void next(int delayTime) {    //产生一个0――数组长度的随机数    int positon = new Random().nextInt(mPosition.length);    Message message = Message.obtain();    message.what = CODE;    message.arg1 = positon;    mMyHandler.sendMessageDelayed(message, delayTime);    //每发送一次消息，总数就加一    mTotalCount++;  }  /**   * 图片点击事件   * @param v   * @param event   * @return   */  @Override  public boolean onTouch(View v, MotionEvent event) {    //每次触碰到地鼠，则地鼠消失，打到地鼠的数量加一    v.setVisibility(View.GONE);    mSuccessCount++;    mTextView.setText("打到了" + mSuccessCount + "只，共" + MAX_COUNT + "只");    return false;  }  public static class MyHandler extends Handler {    private final WeakReference mWeakReference;    public MyHandler(MainActivity activity) {      this.mWeakReference = new WeakReference<>(activity);    }    @Override    public void handleMessage(Message msg) {      MainActivity activity = mWeakReference.get();      super.handleMessage(msg);      switch (msg.what) {        case CODE:          if (activity.mTotalCount > MAX_COUNT) {            //游戏结束，初始化游戏            activity.clear();            Toast.makeText(activity, "地鼠打完了！", Toast.LENGTH_SHORT).show();            return;          } else {            int position = msg.arg1;            activity.mImageView.setX(activity.mPosition[position][0]);            activity.mImageView.setY(activity.mPosition[position][1]);            activity.mImageView.setVisibility(View.VISIBLE);            //在随机位置上显示地鼠之后，再次发送消息            int randomTime = new Random().nextInt(RANDOM_NUMBER) + RANDOM_NUMBER;            activity.next(randomTime);          }          break;      }    }  }  /**   * 游戏结束，初始化游戏   */  private void clear() {    mTotalCount = 0;    mSuccessCount = 0;    mImageView.setVisibility(View.GONE);    mButton.setText("点击开始");    mButton.setEnabled(true);  }}
