如何获取并运行Android平台上的2048游戏源码？

由于2048游戏的源码较长，我将为您提供一个简化版的Android 2048游戏源码，您可以根据需要进行修改和扩展。

创建一个名为MainActivity.java的文件，内容如下：

package com.example.myapplication;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
    private GameView gameView;
    private TextView scoreTextView;
    private Button restartButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        gameView = findViewById(R.id.game_view);
        scoreTextView = findViewById(R.id.score_text_view);
        restartButton = findViewById(R.id.restart_button);
        restartButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                gameView.restartGame();
                updateScore();
            }
        });
    }
    private void updateScore() {
        scoreTextView.setText("得分： " + gameView.getScore());
    }
}

创建一个名为GameView.java的文件，内容如下：

package com.example.myapplication;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.Point;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import java.util.ArrayList;
import java.util.List;
import java.util.Random;
public class GameView extends View {
    private static final int SIZE = 4;
    private int[][] board = new int[SIZE][SIZE];
    private int score = 0;
    private boolean moved = false;
    private List<Point> emptyCells = new ArrayList<>();
    private Random random = new Random();
    private Paint paint = new Paint();
    public GameView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initBoard();
    }
    private void initBoard() {
        for (int i = 0; i < SIZE; i++) {
            for (int j = 0; j < SIZE; j++) {
                board[i][j] = 0;
            }
        }
        addRandomTile();
        addRandomTile();
    }
    private void addRandomTile() {
        if (emptyCells.isEmpty()) {
            return;
        }
        Point point = emptyCells.remove(random.nextInt(emptyCells.size()));
        board[point.x][point.y] = random.nextInt(10) == 0 ? 4 : 2;
    }
    private void moveLeft() {
        // TODO: 实现向左移动的逻辑
    }
    private void moveRight() {
        // TODO: 实现向右移动的逻辑
    }
    private void moveUp() {
        // TODO: 实现向上移动的逻辑
    }
    private void moveDown() {
        // TODO: 实现向下移动的逻辑
    }
    private void updateEmptyCells() {
        emptyCells.clear();
        for (int i = 0; i < SIZE; i++) {
            for (int j = 0; j < SIZE; j++) {
                if (board[i][j] == 0) {
                    emptyCells.add(new Point(i, j));
                }
            }
        }
    }
    private void mergeTiles() {
        // TODO: 实现合并相同数字的逻辑
    }
    private void checkGameOver() {
        // TODO: 检查游戏是否结束的逻辑
    }
    public void restartGame() {
        initBoard();
        invalidate();
    }
    public int getScore() {
        return score;
    }
    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        drawBoard(canvas);
    }
    private void drawBoard(Canvas canvas) {
        for (int i = 0; i < SIZE; i++) {
            for (int j = 0; j < SIZE; j++) {
                int value = board[i][j];
                if (value != 0) {
                    paint.setColor(getResources().getColor(value == 2 ? R.color.tile2 : R.color.tile4));
                    canvas.drawRect(j * 100, i * 100, (j + 1) * 100, (i + 1) * 100, paint);
                    paint.setColor(getResources().getColor(R.color.text));
                    paint.setTextSize(50);
                    canvas.drawText(String.valueOf(value), j * 100 + 35, i * 100 + 70, paint);
                }
            }
        }
    }
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        // TODO: 处理触摸事件的逻辑
        return true;
    }
}

在res/values/colors.xml文件中添加颜色资源：

<?xml version="1.0" encoding="utf8"?>
<resources>
    <color name="tile2">#ffeeee</color>
    <color name="tile4">#ffdddd</color>
    <color name="text">#ffffff</color>
</resources>

这个简化版的代码仅提供了基本的游戏框架，您需要自行实现移动、合并和游戏结束等逻辑，希望这对您有所帮助！
