为什么带libgdx引擎的助手在加载我的图像时会崩溃？

Question

我用手机上的助手用libgdx引擎编写了这个程序。当我运行程序时，它几乎立即崩溃。我没有机会做很多事情，但我已经把问题缩小到了尝试加载自己的图片。当我删除/禁用代码"Texture(Gdx.files.internal("button_center.png"));“时，程序能够运行。另一个映像是在启动项目时预先加载的，没有出现任何问题。我尝试将我的图像移到相同的文件夹中，然后刷新构建，但是应用程序仍然崩溃。

下面是代码：

package pavlov.murderdoggyalpha;

import com.badlogic.gdx.*;
import com.badlogic.gdx.graphics.*;
import com.badlogic.gdx.graphics.g2d.*;
import pavlov.murderdoggyalpha.*;



public class MyGdxGame implements ApplicationListener
{
    Texture texture;
    Texture butDownLeft;
    Texture butLeft;
    Texture butUpLeft;
    Texture butDown;
    Texture butCenter;
    Texture butUp;
    Texture butDownRight;
    Texture butRight;
    Texture butUpRight;
    SpriteBatch batch;
    int touchX;
    int touchY;


    @Override
    public void create()
    {
        texture = new Texture(Gdx.files.internal("android.jpg"));
        butCenter = new Texture(Gdx.files.internal("button_center.png"));
        batch = new SpriteBatch();
    }

    @Override
    public void render()
    {        
        Gdx.gl.glClearColor(1, 1, 1, 1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        batch.begin();

        batch.draw(texture, touchX, touchY, 
                   Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
            if (Gdx.input.justTouched());
            {
                touchX = Gdx.input.getX();
                touchY = Gdx.input.getY();
            }
        batch.end();

    }

    @Override
    public void dispose()
    {
    }

    @Override
    public void resize(int width, int height)
    {
    }

    @Override
    public void pause()
    {
    }

    @Override
    public void resume()
    {
    }

}

我相信这是错误日志。我提前道歉，我是新手。

这一点在我看来尤为突出：

原因: java.io.IOException:无法仅加载像素映射8位。

剩下的是：。

Answer 1

通过谷歌搜索“引起: java.io.IOException:无法只加载像素图8位”，我发现由于某种原因，它在加载16位png图像时遇到了问题。我不知道如何将其转换为8位图像，所以我去吃午餐，并将文件扩展名交换为gif。该应用程序现在运行良好。
