android渲染纹理区域显示黑框[Java Libgdx]

Question

在Android中渲染纹理区域而不是获取图像（我在桌面上获得）时，我只得到黑盒而不是图像。我觉得这将与图像的不寻常的4495 * 260px大小有关。 这是纹理区域的代码：

        walkSheet = new Texture(Gdx.files.internal("data/spritesheet5.png"));

        upFarmer1 = new Sprite (walkSheet, 0, 0, 145, 130);  

        upFarmer2 = new Sprite (walkSheet, 170, 0, 170, 170);
        upFarmer3 = new Sprite (walkSheet, 340, 0, 170, 170);
        upFarmer4 = new Sprite (walkSheet, 680, 0, 170, 170);
        upFarmer5 = new Sprite (walkSheet, 0, 170, 170, 170);
        upFarmer6 = new Sprite (walkSheet, 170, 170, 170, 170);
        upFarmer7= new Sprite (walkSheet, 340, 170, 170, 170);
        upFarmer8= new Sprite (walkSheet, 680, 170, 170, 170);

        TextureRegion[][] tmp = TextureRegion.split(walkSheet, walkSheet.getWidth()/FRAME_COLS, walkSheet.getHeight()/FRAME_ROWS);              // #10
        walkFrames = new TextureRegion[FRAME_COLS * FRAME_ROWS];

        int index = 0;
        for (int i = 0; i < FRAME_ROWS; i++) {
            for (int j = 0; j < FRAME_COLS; j++) {
                walkFrames[index++] = tmp[i][j];
            }
        }
//        walkAnimation = new Animation(0.225f, walkFrames);      // #11
        walkAnimation = new Animation(1/90f, walkFrames);      // #11
        spriteBatch = new SpriteBatch();                // #12
        stateTime = 0f;
        }

我一直在使用libgdx，我认为它使用GL20或GL10，但是我对这些没什么经验，如果它们是问题，请指导我到我应用程序中解决问题的位置。
