我正在尝试开发一款应用游戏，其中包含显示 12 张卡片，当您选择 3 张卡片时，这些卡片会被替换。我为此建立了两个类，“位置”和“卡片”。onCreate()我制作了 72 张卡片并将它们添加到一个ArrayList并创建 12 个位置，这 12 个位置有一个 int 作为输入，无论是否选择和一张卡片。该卡的输入之一是 , R.drawable.image1，并且在我的输入中我输入ImageAdapter了我的mThumbIds, MainActivity.p1.getCard().getImage()。p1是位置的静态实例，所有卡片也是静态的。当一个位置被点击时，它被选中，当其中 3 个被选中时，我有：

    if (deck.size() > 0) {
        countSel.get(0).setCard(deck.remove(0));
        countSel.get(1).setCard(deck.remove(1));
        countSel.get(2).setCard(deck.remove(2));
        gridview.invalidateViews();
    }

其中，deck 包含所有卡片，并且countSel只有 3 张选定的卡片。所以基本上，现在我的 mThumbIds 中的位置有新卡片和新图片，但即使卡片更新，图像也不会更新。

感谢您的帮助，这是我的其余代码：

图像适配器：

package com.example.set;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
public class ImageAdapter extends BaseAdapter {
private Context mContext;



public ImageAdapter(Context c) {
    mContext = c;
}

public int getCount() {
    return mThumbIds.length;
}

public Object getItem(int position) {
    return null;
}

public  Integer[] getmThumbIds() {
    return mThumbIds;
}

public  void setmThumbIds(Integer[] mThumbIds) {
    this.mThumbIds = mThumbIds;
}

public long getItemId(int position) {
    return 0;
}

// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageView;
    if (convertView == null) {  // if it's not recycled, initialize some attributes
        imageView = new ImageView(mContext);
        imageView.setLayoutParams(new GridView.LayoutParams(200, 200));
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setPadding(8, 8, 8, 8);
        notifyDataSetChanged();
    } else {
        imageView = (ImageView) convertView;
    }

    imageView.setImageResource(mThumbIds[position]);
    notifyDataSetChanged();
    return imageView;
}




// references to our images
public Integer[] mThumbIds = {
        MainActivity.p1.getCard().getImage() , MainActivity.p2.getCard().getImage(), 
        MainActivity.p3.getCard().getImage(),MainActivity.p4.getCard().getImage() , 
        MainActivity.p5.getCard().getImage(), MainActivity.p6.getCard().getImage(),
        MainActivity.p7.getCard().getImage() , MainActivity.p8.getCard().getImage(), 
        MainActivity.p9.getCard().getImage(), MainActivity.p10.getCard().getImage() , 
        MainActivity.p11.getCard().getImage(), MainActivity.p12.getCard().getImage(),
        MainActivity.p13.getCard().getImage() , MainActivity.p14.getCard().getImage(), 
        MainActivity.p15.getCard().getImage()
};

}

活动主.xml：

    <?xml version="1.0" encoding="utf-8"?>
    <GridView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/gridview"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:columnWidth="200dp"
    android:numColumns="3"
    android:verticalSpacing="60dp"
    android:horizontalSpacing="20dp"
    android:stretchMode="columnWidth"
    android:gravity="center"
    />

这是我尝试刷新gridview的部分，如果有人认为错误存在，我将发布其余代码，我只是很难正确格式化它：

        super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final GridView gridview = (GridView) findViewById(R.id.gridview);
    gridview.setAdapter(new ImageAdapter(this));

    gridview.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {
            if (position == 0) {
                choose(p1);
            } else if (position == 1) {
                choose(p2);
            } else if (position == 2) {
                choose(p3);
            } else if (position == 3) {
                choose(p4);
            } else if (position == 4) {
                choose(p5);
            } else if (position == 5) {
                choose(p6);
            } else if (position == 6) {
                choose(p7);
            } else if (position == 7) {
                choose(p8);
            } else if (position == 8) {
                choose(p9);
            } else if (position == 9) {
                choose(p10);
            } else if (position == 10) {
                choose(p11);
            } else if (position == 11) {
                choose(p12);
            } else if (position == 12) {
                choose(p13);
            } else if (position == 13) {
                choose(p14);
            } else if (position == 14) {
                choose(p15);
            } else {
            }
            if (countSel.size() == 3) {
                countSel.get(0).setChosen(0);
                countSel.get(1).setChosen(0);
                countSel.get(2).setChosen(0);
        if (set(countSel.get(1), countSel.get(2), countSel.get(0))) {
                    {
        Toast.makeText(MainActivity.this, "Got a Set",
            Toast.LENGTH_LONG).show();
                    }

                    if (deck.size() > 0) {
                    countSel.get(0).setCard(deck.remove(0));
                    countSel.get(1).setCard(deck.remove(1));
                    countSel.get(2).setCard(deck.remove(2));

                    } else {
                        countSel.get(0).setCard(cardnull);
                        countSel.get(1).setCard(cardnull);
                        countSel.get(2).setCard(cardnull);

                    }
                } else {
                    Toast.makeText(MainActivity.this,
            "Not A Set" + "remaining" + countSel.size(),
                            Toast.LENGTH_LONG).show();
                }
                countSel.clear();
            }

            {
        Toast.makeText(MainActivity.this,
                    "chicken" + "remaining" +countSel.size(),
                        Toast.LENGTH_SHORT).show();
            }

        }
    });
    gridview.invalidateViews();
}

public void choose(Position p) {
    if (p.getChosen() == 0) {
        p.setChosen(1);
        countSel.add(p);

    }

    else if (p.getChosen() == 1) {
        p.setChosen(0);
        countSel.remove(p);
        System.out.println(countSel.size());
    } else
        System.out.println("emo");
}
