我的问题是，从几天前开始，我的 androidPlot 图形运行良好，我以简单的布局将图形内的所有数据悲伤，但是，我合并了一个库“Viewpagerindicator”，以更好地处理资金的进入和退出关系, 然后, 一切正常, 只是现在看不到图形里面的元素, 这里有图片点击这里
“Ingreso”和“Egreso”是我在我的主要布局中添加的两个布局，是两个活动，我在我的图形“Egreso”或“Ingreso”类中没有触及任何东西，只是添加它们。我不明白为什么我看不到它。
我认为这是我的主要 laoyut 中的 viewpager 标签中的内容，因为我在其他简单的布局中使用它，我看到了图形。请帮忙。附加我的代码。
