用android studio做一个打地鼠小游戏

以下是使用Android Studio实现打地鼠小游戏的步骤：

1.创建一个新的Android Studio项目，选择Empty Activity模板。

2.在app/build.gradle文件中添加以下依赖项：

dependencies {
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
}

3.在activity_main.xml文件中添加一个RelativeLayout布局，并在其中添加一个ImageView元素，用于显示地鼠图片。

4.创建一个名为Mouse的Java类，用于表示地鼠对象。该类应该包含以下属性：

public class Mouse {
    private int x;
    private int y;
    private boolean visible;

    public Mouse(int x, int y) {
        this.x = x;
        this.y = y;
        this.visible = false;
    }

    public int getX() {
        return x;
    }

    public int getY() {
        return y;
    }

    public boolean isVisible() {
        return visible;
    }

    public void setVisible(boolean visible) {
        this.visible = visible;
    }
}

5.在MainActivity.java文件中添加以下代码：

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    private ImageView mouseImageView;
    private Mouse mouse;
    private Handler handler;
    private int score;

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

        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

        mouseImageView = findViewById(R.id.mouseImageView);
        mouseImageView.setOnClickListener(this);

        mouse = new Mouse(0, 0);

        handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                update();
                handler.postDelayed(this, 1000);
            }
        }, 1000);
    }

    private void update() {
        Random random = new Random();
        int x = random.nextInt(mouseImageView.getWidth() - mouseImageView.getDrawable().getIntrinsicWidth());
        int y = random.nextInt(mouseImageView.getHeight() - mouseImageView.getDrawable().getIntrinsicHeight());

        mouse.setX(x);
        mouse.setY(y);
        mouse.setVisible(true);

        mouseImageView.setX(x);
        mouseImageView.setY(y);
        mouseImageView.setVisibility(View.VISIBLE);
    }

    @Override
    public void onClick(View v) {
        if (mouse.isVisible()) {
            score++;
            Toast.makeText(this, "Score: " + score, Toast.LENGTH_SHORT).show();
            mouse.setVisible(false);
            mouseImageView.setVisibility(View.INVISIBLE);
        }
    }
}

6.运行应用程序，您应该能够看到一个ImageView元素，该元素将在屏幕上随机显示，并且当用户单击它时，将显示一个Toast消息，显示用户的得分。
