I m 撰写综合意见,超越ViewGroup

public class CompositeView extends RelativeLayout

在确定测量结果之后,我需要做一些一次性的初始工作(即,要求采取措施),因为我需要知道高度。

I was thinking of overriding onAttachedToWindow, but the docs mention that:

可在第一次表决之前,包括在会议举行之前或之后,将其称作会议。

What other options do I have?

Thanks

最佳回答

我更愿意在我的习俗意见中援引:

@Override
protected void onSizeChanged(final int w, final int h, final int oldw, final int oldh) {
    boolean changed = false;
    changed |= w != oldw;
    changed |= h != oldh;
    changed &= w > 0;
    changed &= h > 0;
    if (changed) {
            //do initialization stuff here
            ...

This method is called once after layouting is finished. This questions gives some extra details.
