It seems I am not able to get the startingPlayerLayout to the front of other Views. I have tried multiple solutions, the last one being the code below, which as a result keeps the LinearLayout visible but in the background... (It's my very first question on Stack Overflow, please excuse any mistakes) Thanks to everyone
public class MainActivity extends AppCompatActivity {
boolean gameFinished = false;
// Player 1 = Black, Player 2 = Red
int playerActive;
int[] gameState = {0, 0, 0, 0, 0, 0, 0, 0, 0};
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}};
TextView gameInfoField;
Button playAgainButton;
LinearLayout startingPlayerLayout;
ConstraintLayout baseLayout;
// The actual gameplay follows:
public void player1Starts(View view) {
playerActive = 1;
startingPlayerLayout.setVisibility(View.INVISIBLE);
}
public void player2Starts(View view) {
playerActive = 2;
startingPlayerLayout.setVisibility(View.INVISIBLE);
}
public void playCounter(View view) {
ImageView counter = (ImageView) view;
int squarePlayed = Integer.parseInt(counter.getTag().toString());
gameInfoField = (TextView) findViewById(R.id.gameInfoField);
if (!gameFinished) {
if (gameState[squarePlayed] == 0) {
counter.setTranslationY(-1000f);
if (playerActive == 1) {
counter.setImageResource(R.drawable.token_black);
gameState[squarePlayed] = 1;
playerActive = 2;
gameInfoField.setText("Tocca al ROSSO");
} else {
counter.setImageResource(R.drawable.token_red);
gameState[squarePlayed] = 2;
playerActive = 1;
gameInfoField.setText("Tocca al NERO");
}
counter.animate().translationYBy(1000f);
} else if (gameState[squarePlayed] == 0 && !gameFinished) {
Toast.makeText(getApplicationContext(), "La casella è già occupata", Toast.LENGTH_SHORT).show();
}
// Need to check if there's a winner, or if it's a draw:
for (int[] winningPosition : winningPositions) {
playAgainButton = (Button) findViewById(R.id.playAgainButton);
if (gameState[winningPosition[0]] == gameState[winningPosition[1]] &&
gameState[winningPosition[1]] == gameState[winningPosition[2]] &&
gameState[winningPosition[0]] != 0) {
gameFinished = true;
if (gameState[winningPosition[0]] == 1) {
gameInfoField.setText("IL NERO VINCE!");
} else {
gameInfoField.setText("IL ROSSO VINCE!");
}
gameFinished = true;
playAgainButton.setVisibility(View.VISIBLE);
}
boolean fullBoard = true;
for (int square : gameState) {
if (square == 0) {
fullBoard = false;
}
}
if (fullBoard && !gameFinished) {
gameInfoField.setText("Pareggio");
playAgainButton.setVisibility(View.VISIBLE);
}
}
} else {
Toast.makeText(getApplicationContext(), "Abbiamo già un vincitore!", Toast.LENGTH_SHORT).show();
}
}
// And finally, we need to be able to play again if we want to:
public void playAgain(View view) {
gameFinished = false;
for (int i = 0; i < gameState.length; i++) {
gameState[i] = 0;
}
GridLayout board = (GridLayout) findViewById(R.id.board);
for (int i = 0; i < board.getChildCount(); i++) {
((ImageView) board.getChildAt(i)).setImageResource(0);
}
playAgainButton.setVisibility(View.INVISIBLE);
baseLayout.bringChildToFront(startingPlayerLayout);
startingPlayerLayout.setVisibility(View.VISIBLE);
if (playerActive == 1) {
gameInfoField.setText("Tocca al NERO");
}
else {
gameInfoField.setText("Tocca al ROSSO");
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
baseLayout = (ConstraintLayout) findViewById(R.id.baseLayout);
startingPlayerLayout = (LinearLayout) findViewById(R.id.startingPlayerLayout);
baseLayout.bringChildToFront(startingPlayerLayout);
startingPlayerLayout.setVisibility(View.VISIBLE);
}
}
And here is the XML file (I tried to move the LinearLayout at the end of it but the problem remains the same):
