中使用ArrayList forEach

怎么样？帮我们！ PLZ。

Java代码

public boolean OnPressEvent(ArrayList<MarkerItem> markers){
// in code
}

{N}的代码

onPressEvent: function(markers: MarkerItem[]) {
// in code (for android)
console.log("length", markers.length) // = undefined
console.log("length", markers.size()) // = 0~n (integer)

// i want run below codes.
markers.forEach(function(marker){
// marker editing....
});
}

最简单的方法是：

onPressEvent: function(markers: MarkerItem[]) {
  var size = markers.size();
  for (var i=0;i<size;i++) {
    var aMarker = markers.get(i);
    // Do whatever I need to do with this item
  }
});
