android打地鼠小游戏源码

以下是一个简单的 Android 打地鼠小游戏的代码示例，供参考：

MainActivity.java

public class MainActivity extends AppCompatActivity {

    private GridLayout gridLayout;
    private int score = 0;
    private TextView scoreText;

    private static final int ROWS = 3;
    private static final int COLUMNS = 4;
    private static final int NUM_MOLES = 6;

    private Mole[] moles = new Mole[NUM_MOLES];

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        gridLayout = findViewById(R.id.grid_layout);
        scoreText = findViewById(R.id.score_text);

        gridLayout.setColumnCount(COLUMNS);
        gridLayout.setRowCount(ROWS);

        for (int i = 0; i < NUM_MOLES; i++) {
            Mole mole = new Mole(this);
            mole.setMoleListener(new MoleListener() {
                @Override
                public void onMoleWhacked() {
                    score++;
                    scoreText.setText("Score: " + score);
                }
            });
            moles[i] = mole;
        }

        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLUMNS; j++) {
                gridLayout.addView(moles[(i * COLUMNS + j) % NUM_MOLES]);
            }
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        for (Mole mole : moles) {
            mole.start();
        }
    }

    @Override
    protected void onPause() {
        super.onPause();
        for (Mole mole : moles) {
            mole.stop();
        }
    }
}

Mole.java

public class Mole extends AppCompatImageView implements View.OnClickListener {

    private static final int ANIMATION_DURATION = 500;

    private Handler handler;
    private MoleListener listener;

    private boolean isUp = false;
    private boolean isRunning = false;

    public Mole(Context context) {
        super(context);
        setImageResource(R.drawable.mole_down);
        setOnClickListener(this);
        handler = new Handler();
    }

    public void setMoleListener(MoleListener listener) {
        this.listener = listener;
    }

    public void start() {
        if (!isRunning) {
            isRunning = true;
            handler.postDelayed(moleRunnable, getRandomDelay());
        }
    }

    public void stop() {
        isRunning = false;
        handler.removeCallbacks(moleRunnable);
    }

    private Runnable moleRunnable = new Runnable() {
        @Override
        public void run() {
            if (isRunning) {
                if (isUp) {
                    animate().alpha(0).setDuration(ANIMATION_DURATION).withEndAction(downRunnable);
                } else {
                    setImageResource(R.drawable.mole_up);
                    animate().alpha(1).setDuration(ANIMATION_DURATION);
                    handler.postDelayed(downRunnable, getRandomDuration());
                }
                isUp = !isUp;
                handler.postDelayed(moleRunnable, getRandomDelay());
            }
        }
    };

    private Runnable downRunnable = new Runnable() {
        @Override
        public void run() {
            if (isRunning) {
                setImageResource(R.drawable.mole_down);
            }
        }
    };

    private int getRandomDelay() {
        return (int) (Math.random() * 3000 + 1000);
    }

    private int getRandomDuration() {
        return (int) (Math.random() * 1000 + 500);
    }

    @Override
    public void onClick(View v) {
        if (isUp) {
            if (listener != null) {
                listener.onMoleWhacked();
            }
            animate().alpha(0).setDuration(ANIMATION_DURATION).withEndAction(downRunnable);
            isUp = false;
        }
    }
}

MoleListener.java

public interface MoleListener {
    void onMoleWhacked();
}

布局文件 activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <GridLayout
        android:id="@+id/grid_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerInParent="true"
        app:columnCount="4"
        app:rowCount="3" />

    <TextView
        android:id="@+id/score_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:text="Score: 0"
        android:textSize="20sp" />

</RelativeLayout>

图片资源

在 drawable 文件夹中添加 mole_down.png 和 mole_up.png 两张图片，分别代表地鼠下蹲和跳起来的状态。

这是一个简单的打地鼠小游戏，仅供参考。
