嘿大家好，我正在尝试在 Activity 上显示 2 个折线图，当我更改代码以仅显示 1 个图表时，它可以工作，但是当我添加第二个图表时，仅显示第一个图表，而第一个图表消失了.
这是 Activity

知道哪里出了问题吗？
最佳答案
获取chartview的引用后更改此行
//prepareGraphTop method
AnyChartView top = findViewById(R.id.top_soil);
APIlib.getInstance().setActiveAnyChartView(top);
//prepareGraphBot method
AnyChartView bottom = findViewById(R.id.bottom_soil);
APIlib.getInstance().setActiveAnyChartView(bottom);
