安卓翻翻乐小游戏代码怎么写

以下是一个简单的安卓翻翻乐小游戏的代码示例：

1. 首先，在XML布局文件中创建一个GridView，用于呈现游戏的方格：

<GridView
    android:id="@+id/gridview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:numColumns="4"
    android:verticalSpacing="5dp"
    android:horizontalSpacing="5dp"
    android:padding="5dp"
    android:stretchMode="columnWidth"
    android:gravity="center" />

2. 在Java代码中创建一个Adapter来为GridView提供数据：

public class GridAdapter extends BaseAdapter {
    private Context mContext;
    private int[] mImageIds;
    private boolean[] mIsFlipped;
    private int mFlippedCount;
    private int mFirstFlippedIndex;
    private int mSecondFlippedIndex;

    public GridAdapter(Context context, int[] imageIds) {
        mContext = context;
        mImageIds = imageIds;
        mIsFlipped = new boolean[imageIds.length];
        mFlippedCount = 0;
        mFirstFlippedIndex = -1;
        mSecondFlippedIndex = -1;
    }

    @Override
    public int getCount() {
        return mImageIds.length;
    }

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

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

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        ImageView imageView;
        if (convertView == null) {
            imageView = new ImageView(mContext);
            imageView.setLayoutParams(new GridView.LayoutParams(150, 150));
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(8, 8, 8, 8);
        } else {
            imageView = (ImageView) convertView;
        }

        if (mIsFlipped[position]) {
            imageView.setImageResource(mImageIds[position]);
        } else {
            imageView.setImageResource(R.drawable.back);
        }

        imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (!mIsFlipped[position]) {
                    flipCard(position);
                }
            }
        });

        return imageView;
    }

    private void flipCard(int position) {
        mIsFlipped[position] = true;
        mFlippedCount++;

        if (mFirstFlippedIndex == -1) {
            mFirstFlippedIndex = position;
        } else {
            mSecondFlippedIndex = position;

            if (mImageIds[mFirstFlippedIndex] == mImageIds[mSecondFlippedIndex]) {
                // Matched
                mIsFlipped[mFirstFlippedIndex] = true;
                mIsFlipped[mSecondFlippedIndex] = true;
                mFirstFlippedIndex = -1;
                mSecondFlippedIndex = -1;
                mFlippedCount = 0;
            } else {
                // Not matched
                Handler handler = new Handler();
                handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mIsFlipped[mFirstFlippedIndex] = false;
                        mIsFlipped[mSecondFlippedIndex] = false;
                        mFirstFlippedIndex = -1;
                        mSecondFlippedIndex = -1;
                        mFlippedCount = 0;
                        notifyDataSetChanged();
                    }
                }, 1000);
            }
        }

        notifyDataSetChanged();
    }
}

3. 在Activity中初始化GridView并设置Adapter：

public class MainActivity extends AppCompatActivity {
    private int[] mImageIds = { 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.image1, R.drawable.image2, R.drawable.image3, R.drawable.image4,
            R.drawable.image5, R.drawable.image6, R.drawable.image7, R.drawable.image8 };
    private GridView mGridView;

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

        mGridView = findViewById(R.id.gridview);
        mGridView.setAdapter(new GridAdapter(this, mImageIds));
    }
}

这个示例只是一个简单的翻翻乐小游戏，你可以根据需要添加更多的功能和特性。
