java - 应用程序在网格布局声明部分崩溃

问题描述

类和 XML 不一样

public void r(View view)
        {
            LinearLayout linearLayout=findViewById(R.id.playAgain);
            linearLayout.setVisibility(View.INVISIBLE);

            activePLayer=0 ;

            for(int i=0;i<9;i++)
            {
                gameState[i]=2;
            }

            Log.i("Success","0");
//Till this part it's working

            GridLayout gridL = findViewById(R.id.gl);
            Log.i("Success","0");
//This log don't show up

            for(int i=0;i<gridL.getChildCount();i++)
            {
                ((ImageView)gridL.getChildAt(i)).setImageResource(0);
            }

        }

我想重置我在约束布局中制作的 Connect-3 游戏以再次播放它，但我的应用程序在声明 GridLayout 时崩溃。有什么建议么？

我的构建错误日志：-
