Это Основная деятельность 

package com.example.connect3;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;

public class MainActivity extends AppCompatActivity {

// 0 = yellow, 1 = red

int activePlayer = 0;

// 2 means unplayed

int[] gameState = {2, 2, 2, 2, 2, 2, 2, 2, 2};

int[][] winningPositions = {{0,1,2}, {3,4,5}, {6,7,8}, {0,3,6}, {1,4,7}, {2,5,8}, {0,4,8}, {2,4,6}};

public void dropIn(View view) {

    ImageView counter = (ImageView) view;

    int tappedCounter = Integer.parseInt(counter.getTag().toString());

    if (gameState[tappedCounter] == 2) {

        gameState[tappedCounter] = activePlayer;

        counter.setTranslationY(-1000f);

        if (activePlayer == 0) {

            counter.setImageResource(R.drawable.yellow);

            activePlayer = 1;

        } else {

            counter.setImageResource(R.drawable.red);

            activePlayer = 0;

        }

        counter.animate().translationYBy(1000f).rotation(360f).setDuration(300);

        for (int[] winningPosition : winningPositions) {

            if (gameState[winningPosition[0]] == gameState[winningPosition[1]] &&
                    gameState[winningPosition[1]] == gameState[winningPosition[2]] &&
                    gameState[winningPosition[0]] != 2) {

                System.out.println(gameState[winningPosition[0]]);

            }

        }

    }

}

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

}
}
