mpAndroidChart java.lang.NegativeArraySizeException：-46代表科特林
提问于 2021-06-29 16:03:10
我已经搜索了谷歌，并尝试了一些“解决方案”，但没有一个对我有用。我使用的是'com.github.PhilJay:MPAndroidChart:v3.1.0‘，并试图制作一个线状图。
错误代码如下：

我的代码如下：
private fun setMountain(mChart: LineChart){
val entries = ArrayList<Entry>()
entries.add(Entry(20.9f, 100f))
entries.add(Entry(20.1f, 304f))
entries.add(Entry(19.4f, 609f))
entries.add(Entry(18.6f, 914f))
entries.add(Entry(17.9f, 1219f))
entries.add(Entry(17.3f, 1524f))
entries.add(Entry(16.6f, 1828f))
entries.add(Entry(16f, 2133f))
entries.add(Entry(15.4f, 2438f))
entries.add(Entry(14.8f, 2743f))
entries.add(Entry(14.3f, 3048f))
entries.add(Entry(13.7f, 3352f))
entries.add(Entry(13.2f, 3657f))
entries.add(Entry(12.7f, 3962f))
entries.add(Entry(12.3f, 4267f))
entries.add(Entry(11.8f, 4572f))
entries.add(Entry(11.4f, 4876f))
entries.add(Entry(11f, 5181f))
entries.add(Entry(10.5f, 5486f))
entries.add(Entry(10.1f, 5791f))
entries.add(Entry(9.7f, 6096f))
entries.add(Entry(9.4f, 6400f))
entries.add(Entry(9f, 6705f))
entries.add(Entry(8.7f, 7010f))
entries.add(Entry(8.4f, 7315f))
entries.add(Entry(8.1f, 7620f))
entries.add(Entry(7.8f, 7924f))
entries.add(Entry(7.5f,8229f))
entries.add(Entry(7.2f,8534f))
entries.add(Entry(6.9f,8839f))
entries.add(Entry(6.3f,9144f))
val dataSet = LineDataSet(entries, "label")
mChart.data = LineData(dataSet)
mChart.invalidate()
mChart.xAxis.position = XAxis.XAxisPosition.BOTTOM
}我试着看了以下解决方案，MPChart java.lang.NegativeArraySizeException: -54 https://github.com/PhilJay/MPAndroidChart/issues/2403
但还是不起作用。我迷路了。任何帮助都是非常感谢的。谢谢
编辑:哟，没门，现在一切都好了。我又搜索了一遍，发现了以下线程：https://github.com/PhilJay/MPAndroidChart/issues/2074#issuecomment-238458565
通过添加
Collections.sort(entries, EntryXComparator())开始起作用了。比我好，因为它已经解决了，但是现在起作用了。
