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 + "]";
  }
}

3、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);

    //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) {

        new AlertDialog.Builder(GameActivity.this).setTitle("游戏信息")

            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:padding="3dp" />

</LinearLayout>

注意:pic_view图片资源自行更换
