如何制作按钮弹出动画？

Question

在我的TicTacToe游戏中，我希望获胜的三个字母弹出，然后恢复到正常大小以产生弹出效果。

我相信代码应该在方法winAnimation下的注释中。我尝试过一个for循环，以将字体大小增加1，但是直到for循环完成执行后，它才会显示在屏幕上。

public class button1 extends AppCompatActivity implements View.OnClickListener {
private Button[][] buttons = new Button[3][3];
private boolean player1Turn = true;
private int roundCount = 0;
private int player1Points = 0;
private int player2Points = 0;
private int winCondition;
/*winCondition
    0 = first row
    1 = second row
    2 = third row
    3 = first column
    4 = second column
    5 = third column
    6 = top left to bottom right diagonal
    7 = top right to bottom left diagonal
        */

private TextView textViewPlayer1;
private TextView textViewPlayer2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_button1);
    textViewPlayer1 = findViewById(R.id.player1__number_score);
    textViewPlayer2 = findViewById(R.id.player2__number_score);

    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            String buttonID = "button_" + i + j;
            int resID = getResources().getIdentifier(buttonID, "id", getPackageName());
            buttons[i][j] = findViewById(resID);
            buttons[i][j].setOnClickListener(this);
        }
    }
}


@Override
public void onClick(View view) {
    if (!((Button) view).getText().toString().equals("")) {
        return;
    }
    if (player1Turn) {
        ((Button) view).setText("X");
    } else {
        ((Button) view).setText("O");

    }
    roundCount++;
    if (checkForWin()) {
        if (player1Turn) {
            player1Wins();
