BroadcastReceiver替换GridView中的单个单元

public class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // 处理接收到的广播
        if ("ACTION_UPDATE_ITEM".equals(intent.getAction())) {
            int positionToUpdate = intent.getIntExtra("position", -1);
            if (positionToUpdate != -1) {
                // 更新 GridView 中的指定项
                updateGridViewItem(context, positionToUpdate);
            }
        }
    }

    private void updateGridViewItem(Context context, int position) {
        // 获取 GridView 实例并更新指定位置的项
        GridView gridView = ((Activity) context).findViewById(R.id.gridView);
        if (gridView != null) {
            // 假设有一个 Adapter 来管理 GridView 的数据
            MyAdapter adapter = (MyAdapter) gridView.getAdapter();
            if (adapter != null) {
                // 更新数据集并通知 Adapter 数据变化
                adapter.updateItem(position);
                adapter.notifyItemChanged(position);
            }
        }
    }
}
