Initialize array in Kotlin based on list size - arraylist

Question

I need to add LineChart(using MpAndroidChart) dynamically in LinearLayout.
I have declared an arrayList,named list.
val list = arrayListOf<ABC>()
....
for (i in list) {
chart[] = LineChart(activity)
}
What is the value I should put inside [] ? Let say the list's saiz is 2, I need to have 2 chart in LinearLayout.
How should I initialize LineChart?
Example
chart[i] = LineChart(activity) ???
LineChart
public class LineChart extends BarLineChartBase<LineData> implements LineDataProvider {
public LineChart(Context context) {
super(context);
}
public LineChart(Context context, AttributeSet attrs) {
super(context, attrs);
}
public LineChart(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void init() {
super.init();
mRenderer = new LineChartRenderer(this, mAnimator, mViewPortHandler);
}
#Override
public LineData getLineData() {
return mData;
}
#Override
protected void onDetachedFromWindow() {
// releases the bitmap in the renderer to avoid oom error
if (mRenderer != null && mRenderer instanceof LineChartRenderer) {
((LineChartRenderer) mRenderer).releaseBitmap();
}
super.onDetachedFromWindow();
}
}

Answer 1

Your question is a little unclear, but I'm following correctly, you can do it in one line like this:
val chart = Array(list.size){ LineChart(list[it]) }
Or:
val chart = list.map{ LineChart(it) }.toTypedArray()
(The latter creates a temporary list, which may be slightly less efficient; but it iterates through the list instead of indexing, which could be faster if the list isn't random-access.)

Answer 2

This is my answer
for (i in 0 unti list.size) {
chart[i] = LineChart(activity)
}
