(Android Studio)我的井字游戏未正确显示获胜者 [英] (Android Studio) My Tic-Tac-Toe game is not showing the winner correctly
本文介绍了(Android Studio)我的井字游戏未正确显示获胜者的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我是Android的初学者.我创建了一个简单的井字游戏.它有一个网格和一个状态栏，用于显示轮到谁和谁赢了.问题在于大多数情况下它显示错误的获胜者.仅在少数情况下，它才能正确显示获胜者.在某些情况下，状态栏甚至会消失.我曾尝试更改String(优胜者)，但没有成功.
这是我的MainActivity.java:
I am a beginner to Android. I have created a simple Tic-Tac-Toe game. It has a grid and a status bar that shows whose turn it is and who has won. The problem is that most of the times it shows the wrong winner. Only in a few situations it shows the winner correctly. In some situations the status bar even disappears. I have tried changing the String (winner) but it did not worked out.
Here is my MainActivity.java:
package com.jashanubhi.tictactoeme;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
int activePlayer = 0;
boolean gameActive = true;
int[] gameState = {2,2,2,2,2,2,2,2,2};
int[][] winningPositions = {{0,1,2}, {3,4,5}, {6,7,8},
{0,4,8}, {2,4,6},
{0,3,6}, {1,4,7}, {2,5,8}};
public void playerTap(View view) {
ImageView img;
img = (ImageView) view;
int tappedImage;
tappedImage = Integer.parseInt(img.getTag().toString());
if(!gameActive){
gameReset(view);
}
if(gameActive) {
if (gameState[tappedImage] == 2) {
gameState[tappedImage] = activePlayer;
img.setTranslationY(-1000f);
if (activePlayer == 0) {
img.setImageResource(R.drawable.x);
activePlayer = 1;
TextView status;
status = findViewById(R.id.status);
status.setText("O's Turn - Tap to Play");
} else {
img.setImageResource(R.drawable.o);
activePlayer = 0;
TextView status;
status = findViewById(R.id.status);
status.setText("X's Turn - Tap to Play");
}
img.animate().translationYBy(1000f).setDuration(300);
}
}
gameActive = true;
for (int[] winningPosition : winningPositions) {
if (gameState[winningPosition[0]] == gameState[winningPosition[1]] && gameState[winningPosition[1]] == gameState[winningPosition[2]]
&& gameState[winningPosition[0]] != 2) {
String winner = null;
if (winningPosition[0] == 0) {
winner = "X has won";
}
if (winningPosition[0] == 1) {
winner = "O has won";
}
TextView status = findViewById(R.id.status);
status.setText(winner);
gameActive = false;
break;
}
}
}
public void gameReset(View view){
activePlayer = 0;
for(int i = 0; i < gameState.length; i++){
gameState[i] = 2;
}
((ImageView)findViewById(R.id.imageView0)).setImageResource(0);
((ImageView)findViewById(R.id.imageView1)).setImageResource(0);
((ImageView)findViewById(R.id.imageView2)).setImageResource(0);
((ImageView)findViewById(R.id.imageView3)).setImageResource(0);
((ImageView)findViewById(R.id.imageView4)).setImageResource(0);
((ImageView)findViewById(R.id.imageView5)).setImageResource(0);
((ImageView)findViewById(R.id.imageView6)).setImageResource(0);
((ImageView)findViewById(R.id.imageView7)).setImageResource(0);
((ImageView)findViewById(R.id.imageView8)).setImageResource(0);
TextView status = findViewById(R.id.status);
status.setText("X's Turn - Tap to Play");
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
这是我的XML:
