这是我的java：

package com.k_pc.tick_tac_toe;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.GridLayout;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {
    // 0 = yellow, 1 = red;
    int activePlayer = 0;

    // 2 means unplayed
    int [] gameState= {2, 2, 2, 2, 2, 2, 2, 2, 2};

    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}};

    public void dropIn (View view){

        ImageView counter = (ImageView) view;

        System.out.println(counter.getTag().toString());

        int tappedCounter = Integer.parseInt(counter.getTag().toString());

        if (gameState[tappedCounter] == 2) {

            gameState[tappedCounter] = activePlayer;

            counter.setTranslationY(-1000f);

            if (activePlayer == 0) {
                counter.setImageResource(R.drawable.yellow);
                activePlayer = 1;
            } else {
                counter.setImageResource(R.drawable.red);
                activePlayer = 0;
            }

            counter.animate().translationYBy(1000f).rotation(360f).setDuration(500);

            for (int [] winningPosition : winningPositions){
                if (gameState[winningPosition[0]] == gameState[winningPosition[1]] &&
                        gameState[winningPosition[1]] == gameState[winningPosition[2]] &&
                        gameState[winningPosition[0]] != 2){

                    //Someone has won

                    String winner = "Red";

                    if (gameState[winningPosition[0]] == 0){

                        winner = "Yellow";
                    }



                    TextView winnerMeassage = (TextView) findViewById(R.id.winnerMessage);
                    winnerMeassage.setText(winner + " has won!");

                    LinearLayout layout = (LinearLayout) findViewById(R.id.playAgainLayout);

                    layout.setVisibility(View.VISIBLE);

                }
            }

        }

    }

    public void playAgain (View view){

        LinearLayout layout = (LinearLayout) findViewById(R.id.playAgainLayout);

        layout.setVisibility(View.INVISIBLE);

        // 0 = yellow, 1 = red;
        activePlayer = 0;

        // 2 means unplayed
        for (int i = 0 ; i < gameState.length ; i++){
            gameState[i] = 2;
        }

        // setting all the images source to nothing


        GridLayout gridLayout = (GridLayout) findViewById(R.id.gridLayout);




        for(int i = 0 ; i<gridLayout.getChildCount() ; i++){

            ((ImageView) gridLayout.getChildAt(i)).setImageResource(0);
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

我不认为代码会有所帮助，但如果你想看到它就在这里。

Answer 1

请检查您的drawable文件夹。有时，当您的图像在v24 drawable文件夹中时，会发生此错误，将图像移动到可绘制文件夹。

Answer 2

尝试使用支持库版本。

通过gradle implementation com.android.support:gridlayout-v7:27.1.1添加

用<GridLayout>取代<android.support.v7.widget.GridLayout>

还可以将导入更改为支持库
