我想制作一个简单的井字游戏。
现在我有这个代码。
在这里，我只需点击一个按钮，它就会变成X，而当我在一行中有3个X时，会有一个Toast显示“游戏结束”。
我还没有设置Os。井字游戏应用程序不工作
public class MainActivity extends AppCompatActivity {
ImageButton[] imageButton = new ImageButton[8];
boolean[] isIt = new boolean[8];
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageButton [0] = (ImageButton) findViewById(R.id.imageButton7) ;
imageButton [1] = (ImageButton) findViewById(R.id.imageButton2) ;
imageButton [2] = (ImageButton) findViewById(R.id.imageButton3) ;
imageButton [3] = (ImageButton) findViewById(R.id.imageButton4) ;
imageButton [4] = (ImageButton) findViewById(R.id.imageButton5) ;
imageButton [5] = (ImageButton) findViewById(R.id.imageButton6) ;
imageButton [6] = (ImageButton) findViewById(R.id.imageButton10) ;
imageButton [7] = (ImageButton) findViewById(R.id.imageButton8) ;
imageButton [8] = (ImageButton) findViewById(R.id.imageButton9) ;
imageButton[0].setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
gunwo(0);
checkIt();
}
});
imageButton[1].setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
gunwo(1);
checkIt();
}
});
imageButton[2].setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
gunwo(2);
checkIt();
}
});
imageButton[3].setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
gunwo(3);
checkIt();
}
});
imageButton[4].setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
gunwo(4);
checkIt();
}
});
imageButton[5].setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
gunwo(5);
checkIt();
}
});
imageButton[6].setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
gunwo(6);
checkIt();
}
});
imageButton[7].setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
gunwo(7);
checkIt();
}
});
imageButton[8].setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
gunwo(8);
checkIt();
}
});
}
public void gunwo(int y)
{
if(!isIt[y])
{
isIt[y] = true;
imageButton[y].setImageResource(R.drawable.trasfasd);
}
}
public void checkIt()
{
if (isIt[0] && isIt[1]&&isIt[2]){
Toast.makeText(getApplicationContext(), "Game Over", Toast.LENGTH_LONG).show();
}
else if(isIt[3]&&isIt[4]&&isIt[5])
{
Toast.makeText(getApplicationContext(), "Game Over", Toast.LENGTH_LONG).show();
}
else if(isIt[6]&&isIt[7]&&isIt[8])
{
Toast.makeText(getApplicationContext(), "Game Over", Toast.LENGTH_LONG).show();
}
else if(isIt[0]&&isIt[3]&&isIt[6])
{
Toast.makeText(getApplicationContext(), "Game Over", Toast.LENGTH_LONG).show();
}
else if(isIt[1]&&isIt[4]&&isIt[7])
{
Toast.makeText(getApplicationContext(), "Game Over", Toast.LENGTH_LONG).show();
}
else if(isIt[2]&&isIt[5]&&isIt[8])
{
Toast.makeText(getApplicationContext(), "Game Over", Toast.LENGTH_LONG).show();
}
else if(isIt[6]&&isIt[4]&&isIt[2])
{
Toast.makeText(getApplicationContext(), "Game Over", Toast.LENGTH_LONG).show();
}
else if(isIt[0]&&isIt[4]&&isIt[8])
{
Toast.makeText(getApplicationContext(), "Game Over", Toast.LENGTH_LONG).show();
}
}
}
编译器没有发现任何错误，但是当我在模拟器应用程序中打开应用程序不工作。
这里是我的logcat：

编译时间检查与运行时异常不同 - 您已检查并取消选中异常。你应该发布相关的堆栈跟踪。 –
如何做到这一点？你可以给我发送代码吗？我是Android Studio中的新成员。 –
您收到的错误是什么？你收到一个错误？你的应用立即关闭？描述您的问题 – firegloves
