我正在创建一个应用程序，根据所选片段显示进度条中的数据，因此如果选择了特定片段，进度条应该显示该片段中的数据等等，在我的应用程序中有三个片段正在进行中的数据bar更新为两个片段，而不是第三个片段，我尝试了日志一切看起来很好，我试过给日志和我想出的是正在打开的片段只有两个，我没有得到第三个日志，即使我打开第三个片段，并且我得到打开第三个片段的指示，如果我再次移回第二个片段，我无法弄清楚我在哪里错过它。下面是我的代码

答案 0 :(得分：0)
你设置了offscreenPaginglimit吗？ 尝试设置
public Animation getWhateverAnimation(int duration){
return super.getWhateverAnimation(0);
}
请告诉我这是否有帮助！
