Question

我正在Kotlin中开发一个应用程序，并且正在使用依赖项GraphView。但是，他们的大多数代码都是用Java编写的，将它们转换为Kotlin时遇到了一些麻烦。有人知道这段Java代码相当于Kotlin吗？

GraphView graph = (GraphView) findViewById(R.id.graph);
LineGraphSeries<DataPoint> series = new LineGraphSeries<DataPoint>(new DataPoint[] {
          new DataPoint(0, 1),
          new DataPoint(1, 5),
          new DataPoint(2, 3),
          new DataPoint(3, 2),
          new DataPoint(4, 6)
});
graph.addSeries(series);

Answer 1

val graph = findViewById(R.id.graph) as GraphView
val series = LineGraphSeries(arrayOf(
          DataPoint(0, 1),
          DataPoint(1, 5),
          DataPoint(2, 3),
          DataPoint(3, 2),
          DataPoint(4, 6)
     )
)
graph.addSeries(series)

但是您可以订购

val graph: GraphView = findViewById(R.id.graph)

graph.addSeries(LineGraphSeries(arrayOf(
          DataPoint(0, 1),
          DataPoint(1, 5),
          DataPoint(2, 3),
          DataPoint(3, 2),
          DataPoint(4, 6)
     )
))

Kotlin中的等效语句
