Question

我正在尝试制作益智游戏。我想使用setTag()/getTag()来确定哪个图块（ImageView）中的图像，并在用户单击一个图块然后单击另一个图块时交换它们。显然，在使用Glide时，您不能使用setTag()/getTag()-You must not call setTag() on a view Glide is targeting

是否有setTag()/getTag()替代方案或最佳解决方案？ -- 滑行新手顺便说一句。

谢谢您的时间。

-这是适配器。 image.setTag()在这里是非法的-

public class ImageAdapter extends BaseAdapter {

    private Context mContext;

    // references to drawables
    private int[] mThumbIds = {
            R.drawable.puzzle_0_0,
            R.drawable.puzzle_0_1,
            R.drawable.puzzle_0_2,
            R.drawable.puzzle_0_3,
            R.drawable.puzzle_1_0,
            R.drawable.puzzle_1_1,
            R.drawable.puzzle_1_2,
            R.drawable.puzzle_1_3,
            R.drawable.puzzle_2_0,
            R.drawable.puzzle_2_1,
            R.drawable.puzzle_2_2,
            R.drawable.puzzle_2_3,
            R.drawable.puzzle_3_0,
            R.drawable.puzzle_3_1,
            R.drawable.puzzle_3_2,
            R.drawable.puzzle_3_3,
    };

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

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

    @Override
    public Object getItem(int position) {
        return mThumbIds[position];
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView image;
        if (convertView == null) {
            image = new ImageView(mContext);
            image.setAdjustViewBounds(true);
        }
        else {
            image = (ImageView) convertView;
        }
        Glide.with(mContext).load(mThumbIds[position]).into(image);
        image.setTag(mThumbIds[position]);

        return image;
    }

    private static void shuffleArray(int[] a) {
        Random rng = new Random();
        for (int i = a.length - 1; i > 0; i--) {
            int index = rng.nextInt(i + 1);
            // Simple swap
            int temp = a[index];
            a[index] = a[i];
            a[i] = temp;
        }
    }
}

-这是getView()-

public class MainActivity extends AppCompatActivity {

    // references to drawables
    private Integer[] mThumbIds = {
            R.drawable.puzzle_0_0,
            R.drawable.puzzle_0_1,
            R.drawable.puzzle_0_2,
            R.drawable.puzzle_0_3,
            R.drawable.puzzle_1_0,
            R.drawable.puzzle_1_1,
            R.drawable.puzzle_1_2,
            R.drawable.puzzle_1_3,
            R.drawable.puzzle_2_0,
            R.drawable.puzzle_2_1,
            R.drawable.puzzle_2_2,
            R.drawable.puzzle_2_3,
            R.drawable.puzzle_3_0,
            R.drawable.puzzle_3_1,
            R.drawable.puzzle_3_2,
            R.drawable.puzzle_3_3,
    };
    public GridView gridView;
    private boolean swapping = false;
    private int firstTilePosition;

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

        gridView = findViewById(R.id.gridView);
        gridView.setAdapter(new ImageAdapter(this));

        gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Log.d("-MyLog-", view.getTag().toString());

                if (!swapping) {
                    firstTilePosition = position;
                    swapping = true;
                }
                else {
                    ImageView firstTile = (ImageView) parent.getChildAt(firstTilePosition);
                    ImageView secondTile = (ImageView) view;

                    int firstTag = (int) firstTile.getTag();
                    int secondTag = (int) secondTile.getTag();

                    Glide.with(MainActivity.this).load(secondTag).into(firstTile);
                    Glide.with(MainActivity.this).load(firstTag).into(secondTile);

                    firstTile.setTag(secondTag);
                    secondTile.setTag(firstTag);

                    // Replace with AlertDialog
                    if ( gameWon(parent) )
                        Toast.makeText(MainActivity.this, "Game Won !!!", Toast.LENGTH_LONG).show();

                    swapping = false;
                }
            }
        });
    }

    private boolean gameWon(AdapterView<?> parent) {
        for (int i = 0; i < parent.getChildCount(); i++) {
            if ( ((int) parent.getChildAt(i).getTag()) != mThumbIds[i] )
                return false;
        }
        return true;
    }

}

您可以为Glide保留默认标签，并自己使用基于密钥的标签。

myButton.setTag(100 /* or any other integer key except 0 */, someValue);

使用Glide时的标记替代
