我必须编写一个 TicTacToe 应用程序:
这是 Activity_main.xml 的代码:(这是一个黑色背景上的 TextViews 的简单 3x3 字段)
这是MainActivity.java的代码:
package com.example.tictactoe;
import androidx.appcompat.app.AppCompatActivity;
import android.content.pm.ActivityInfo;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private int counter = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().hide();
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
public void click_top_left(View v) { click_action((TextView)findViewById(R.id.tictactoe_top_left)); }
public void click_top_center(View v) { click_action((TextView)findViewById(R.id.tictactoe_top_center)); }
public void click_top_right(View v) { click_action((TextView)findViewById(R.id.tictactoe_top_right)); }
public void click_center_left(View v) { click_action((TextView)findViewById(R.id.tictactoe_center_left)); }
public void click_center_center(View v) { click_action((TextView)findViewById(R.id.tictactoe_center_center)); }
public void click_center_right(View v) { click_action((TextView)findViewById(R.id.tictactoe_center_right)); }
public void click_bottom_left(View v) { click_action((TextView)findViewById(R.id.tictactoe_bottom_left)); }
public void click_bottom_center(View v) { click_action((TextView)findViewById(R.id.tictactoe_bottom_center)); }
public void click_bottom_right(View v) { click_action((TextView)findViewById(R.id.tictactoe_bottom_right)); }
public void click_action(TextView tv) {
if ((counter%2)==0)
tv.setText("O");
else
tv.setText("X");
counter++;
}
}
我已将 android:clickable 设置为 true。我设置了一个 onclick 监听器。我根本找不到我的错误......
我将不胜感激任何形式的帮助!
