好，
嗨，大家好，目前正在编写一个Android应用程序，该程序也适用于台式机。
有一个mainMenu，选择创建屏幕，游戏屏幕，但是在最后一个屏幕上，出现了SB错误...
我已经挣扎了两天，
我尝试在屏幕上绘制库存，但出现问题：
Spritebatch.end必须在.begin之前调用，
事实是我真的不知道错误可能从哪里来，告诉我lineX somethingX，在这一行没有Spritebach.end或begin，不知道该怎么办，
有什么提示吗？
public void render() {
stage.draw();
if (Settings.Paused) {
//DO NOTHING
}
}
错误是这样的：
E/LibGDX Utils: SpriteBatch.end must be called before begin.
java.lang.IllegalStateException: SpriteBatch.end must be called before begin.

顺便说一句，我正在使用-不会说很多，但是...-一些静态成员，
为了不像静态那样使用'em，
在课堂上：我创造他们
在另一种方法中：我调用了一些，然后Studio askme将其设置为静态，否则应用程序将无法编译：/
最佳答案
好，
终于多挖一点帮助了我...
问题实际上来自我的一个纹理包，
我在几节课中称呼它，并且随着我的改变，
我忘了更新Item Enum类，
我这样做了，瞧，没有更多的错误... :)
关于java - 解决-与TP相关的问题必须调用Libgdx SpriteBatch.end ...不要捕获错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60818591/
