这篇文章将为大家详细讲解有关Android如何自定义View实现拼图小游戏,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
PuzzleLayoutView:
public class PuzzleLayoutView extends RelativeLayout implements View.OnClickListener { //表示将其切成2*2拼图(默认4块) private int mColumn = 2; //容器的内边距 private int mPadding; //每个块块的边距(横,纵 3:表示间距为3dp) private int mMargin = 3; //存储ImageView private ImageView[] mGamePintuItems; //Item的宽度(一致) private int mItemWidth; //游戏的图片 private Bitmap mBitmap; //切图后的存储 private List<ImagePieceBean> mItemBitmaps; //操作次数 private boolean once; //容器宽度(游戏面板 高宽一致) private int mWidth; //设置游戏是否成功 private boolean isGameSuccess; //设置游戏是否失败 private boolean isGameOver; public GamePintuListner mListner; public PuzzleLayoutView(Context context) { this(context, null);

addView(mAnimLayout);//添加到游戏面板中 } }}
工具类:ImageSplitterUtil
public class ImageSplitterUtil { /** * 传入bitmap,切成piece*piece块 */ public static List<ImagePieceBean> sqlitImage(Bitmap bitmap, int piece) { List<ImagePieceBean> ImagePieceBeans = new ArrayList<>(); int width = bitmap.getWidth();//拿到图片宽高 int height = bitmap.getHeight(); int pieceWidth = Math.min(width, height) / piece;//得到每一块的宽度 for (int i = 0; i < piece; i++) {//切第一行 for (int j = 0; j < piece; j++) {//循环切第二,三行 ImagePieceBean ImagePieceBean = new ImagePieceBean(); ImagePieceBean.setIndex(j + i * piece);//第一次i为0,第0行 j++递增 0-6 int x = j * pieceWidth;//第一次循环X,Y为0 int y = i * pieceWidth; ImagePieceBean.setBitmap(Bitmap.createBitmap(bitmap, x, y, pieceWidth, pieceWidth)); ImagePieceBeans.add(ImagePieceBean); } } return ImagePieceBeans; }}
实体类:ImagePieceBean
public class ImagePieceBean { private int index; //表示当前第几块 private Bitmap bitmap; //当前图片 public ImagePieceBean() { } //快捷键构造方法 Source 倒3 public ImagePieceBean(int index, Bitmap bitmap) { this.index = index; this.bitmap = bitmap; } public int getIndex() { return index; } public void setIndex(int index) { this.index = index; } public Bitmap getBitmap() { return bitmap; } public void setBitmap(Bitmap bitmap) { this.bitmap = bitmap; } public String toString() { return "ImagePiece [index=" + index + ", bitmap=" + bitmap + "]"; }}
使用方法:GameActivity
/** * 总结: * 1.自定义控件选择,九宫格,RelativeLayout, id+Rule * 2.切图 * 3.动画图层 * 4.pause resume restart * 5.游戏时间 Handler sendMessageDelayed() 延迟一秒发送线程 */public class GameActivity extends AppCompatActivity { private PuzzleLayoutView puzzleLayoutView; private TextView mLevel, mTime; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_game); mLevel = this.findViewById(R.id.id_level); mTime = this.findViewById(R.id.id_time); puzzleLayoutView = this.findViewById(R.id.puzzle_layout_view); puzzleLayoutView.setTimeEnabled(true); //监听事件 puzzleLayoutView.setOnGamePintuListner(new PuzzleLayoutView.GamePintuListner() { public void timechanged(int currentTime) { //此处为int 注意加"" mTime.setText(currentTime + "秒"); } public void nextLevel(final int nextLevel) { //弹出提示框 new AlertDialog.Builder(GameActivity.this).setTitle("游戏信息") .setMessage("游戏升级").setPositiveButton("进入下一关", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { //游戏结束后,调用下一关 puzzleLayoutView.nextLevel(); mLevel.setText("第" + +nextLevel + "关"); } }).show(); } public void gameover() { //弹出提示框 new AlertDialog.Builder(GameActivity.this).setTitle("游戏信息") .setMessage("游戏结束!").setPositiveButton("是否继续该关卡?", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { puzzleLayoutView.restart();//重新启动 } }).setNegativeButton("是否放弃该游戏!", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { finish(); } }).show(); } }); }}
对应布局:activity_game
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_margin="10dp" android:gravity="center_horizontal" android:orientation="vertical"> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/id_level" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center" android:text="1" android:textSize="25sp" android:textStyle="bold" /> <TextView android:id="@+id/id_time" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:gravity="center" android:text="120" android:textColor="#ea7821" android:textSize="25sp" android:textStyle="bold" /> </RelativeLayout> <ImageView android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginBottom="10dp" android:src="@drawable/pic_view" /> <com.helloworld.game.utils.PuzzleLayoutView android:id="@+id/puzzle_layout_view" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="3dp" /></LinearLayout>
