我必須編寫一個(gè) TicTacToe 應(yīng)用程序：這是 Activity_main.xml 的代碼：（這是一個(gè)黑色背景上的 TextViews 的簡(jiǎn)單 3x3 字段）這是MainActivity.java的代碼：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++;    }}我已將 android:clickable 設(shè)置為 true。我設(shè)置了一個(gè) onclick 監(jiān)聽(tīng)器。我根本找不到我的錯(cuò)誤......我將不勝感激任何形式的幫助！
