Android ListView vs. getView Call Caton Problem Solution

Solution 1: Set ListView height to a fixed value or match_parent/ifll_parent

@Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { Log.d("onMeasure", "onMeasure"); isOnMeasure = true; super.onMeasure(widthMeasureSpec, heightMeasureSpec); } @Override protected void onLayout(boolean changed, int l, int t, int r, int b) { Log.d("onLayout", "onLayout"); isOnMeasure = false; super.onLayout(changed, l, t, r, b); }

The reason for this is nothing more than that listview needs to dynamically calculate how many views are displayed in it, so it needs to be onMeasure multiple times, and finally onLayout, and onMeasure may need to be executed multiple times.

This is not enough, we in the getview inside the adapt, determine whether it is in onmeasure, if it is, then just mInflater.inflate(R.layout.XXX), and then immediately return to this convertView

If not in the onmeasure, then go to the real onlayout
