使用最新版本Android Studio生成一个简单的拼图游戏

好的，下面是一份简单的拼图游戏的代码，供您参考：

1. 首先，在Android Studio中创建一个新项目，并在XML布局文件中添加一个GridView，用于显示拼图。

2. 创建一个名为PuzzleAdapter的自定义适配器类来管理GridView中的拼图：

public class PuzzleAdapter extends BaseAdapter {
    private Context mContext;
    private int[] mThumbIds;

    public PuzzleAdapter(Context c, int[] thumbIds) {
        mContext = c;
        mThumbIds = thumbIds;
    }

    public int getCount() {
        return mThumbIds.length;
    }

    public Object getItem(int position) {
        return null;
    }

    public long getItemId(int position) {
        return 0;
    }

    // 创建一个新的ImageView来显示GridView中的一个图片
    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imageView;
        if (convertView == null) {
            // 如果convertView没被使用，创建一个新的ImageView
            imageView = new ImageView(mContext);
            imageView.setLayoutParams(new GridView.LayoutParams(200, 200));
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(8, 8, 8, 8);
        } else {
            imageView = (ImageView) convertView;
        }

        imageView.setImageResource(mThumbIds[position]);
        return imageView;
    }
}

3. 创建一个名为PuzzleActivity的活动类，用于管理游戏逻辑和UI：

public class PuzzleActivity extends Activity {
    private Integer[] mThumbIds = {
            R.drawable.image1, R.drawable.image2,
            R.drawable.image3, R.drawable.image4,
            R.drawable.image5, R.drawable.image6,
            R.drawable.image7, R.drawable.image8,
            R.drawable.image9
    };

    private int mColumnWidth, mColumnHeight;
    private GridView mGridView;
    private ArrayList<Bitmap> mBitmaps = new ArrayList<>();
    private Bitmap mLastBitmap;
    private int mBlankPosition;
    private int mLevel = 3;

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

        init();
        shuffle();
    }

    private void init() {
        mGridView = findViewById(R.id.gridview);
        mGridView.setNumColumns(mLevel);

        DisplayMetrics displayMetrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
        int width = displayMetrics.widthPixels;
        int height = displayMetrics.heightPixels;

        mColumnWidth = width / mLevel;
        mColumnHeight = height / mLevel;

        for (int i = 0; i < mThumbIds.length; i++) {
            Bitmap bitmap = BitmapFactory.decodeResource(getResources(), mThumbIds[i]);
            Bitmap scaledBitmap = Bitmap.createScaledBitmap(bitmap, mColumnWidth, mColumnHeight, true);
            mBitmaps.add(scaledBitmap);
        }

        mLastBitmap = mBitmaps.get(mThumbIds.length - 1);
        mBitmaps.remove(mThumbIds.length - 1);

        mBlankPosition = mThumbIds.length - 1;

        mGridView.setAdapter(new PuzzleAdapter(this, mThumbIds));
        mGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                int x = position % mLevel;
                int y = position / mLevel;

                int blankX = mBlankPosition % mLevel;
                int blankY = mBlankPosition / mLevel;

                if ((x == blankX && Math.abs(y - blankY) == 1) || (y == blankY && Math.abs(x - blankX) == 1)) {
                    swap(position, mBlankPosition);
                    mBlankPosition = position;
                }

                checkFinish();
            }
        });
    }

    private void shuffle() {
        Random random = new Random();
        for (int i = 0; i < mThumbIds.length * 2; i++) {
            int position = random.nextInt(mThumbIds.length - 1);
            swap(position, mBlankPosition);
            mBlankPosition = position;
        }
    }

    private void swap(int position1, int position2) {
        Bitmap bitmap1 = mBitmaps.get(position1);
        Bitmap bitmap2 = mBitmaps.get(position2);

        mBitmaps.set(position1, bitmap2);
        mBitmaps.set(position2, bitmap1);

        mThumbIds[position1] = mThumbIds[mThumbIds.length - 1];
        mThumbIds[mThumbIds.length - 1] = mThumbIds[position2];

        PuzzleAdapter puzzleAdapter = new PuzzleAdapter(this, mThumbIds);
        mGridView.setAdapter(puzzleAdapter);
    }

    private void checkFinish() {
        for (int i = 0; i < mThumbIds.length - 1; i++) {
            Bitmap bitmap = mBitmaps.get(i);
            Bitmap thumbBitmap = BitmapFactory.decodeResource(getResources(), mThumbIds[i]);
            if (!bitmap.sameAs(thumbBitmap)) {
                return;
            }
        }

        Toast.makeText(this, "恭喜你完成了拼图游戏！", Toast.LENGTH_SHORT).show();
        mBitmaps.add(mLastBitmap);
        mThumbIds[mThumbIds.length - 1] = R.drawable.image_blank;
        PuzzleAdapter puzzleAdapter = new PuzzleAdapter(this, mThumbIds);
        mGridView.setAdapter(puzzleAdapter);
    }
}

4. 在布局文件中添加GridView：

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/gridview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:columnWidth="90dp"
    android:gravity="center"
    android:numColumns="3"
    android:stretchMode="columnWidth" />

以上就是一个简单的拼图游戏的代码实现。
