Expandable list view move group icon indicator to right in jellyBean 4.3 version?

Question

The below method is not working in android version jellybean 4.3.

historyExpaLV.setIndicatorBounds(historyExpaLV.getRight() - 60,
                    historyExpaLV.getWidth() - 8);

Does anyone know the solution? Thanks in advance.

"not working" is not a very useful explanation of your symptoms. — CommonsWare, Aug 01 '13 at 13:48
Does it work in previous versions? Are you calling it before it's measured? More detail, please. — Geobits, Aug 01 '13 at 13:50

How I fixed this:

Update SDK Manager to Android 4.3 and use it as build target. They introduced a new method in the API 18, called setIndicatorBoundsRelative(int, int), which works as the other (but correctly) in android 4.3.

Make a check for Android version and use the old method with older API:

if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.JELLY_BEAN_MR2) {
   mListView.setIndicatorBounds(myLeft, myRight);
} else {
   mListView.setIndicatorBoundsRelative(myLeft, myRight);
}

What is myLeft, myRight ? Please elaborate it – Anand Savjani Jul 08 '15 at 09:39
myLeft and myRight are your desired values how you want to pad the indicator. They are called "my" because it's up to you to decide what you want them to be. Check out the docs: http://developer.android.com/reference/android/widget/ExpandableListView.html#setIndicatorBounds(int, int) – luben Jul 08 '15 at 11:48

i think it's bug

int right = (int) (getResources().getDisplayMetrics().widthPixels - TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 30, getResources().getDisplayMetrics()));
    expandableListView.setIndicatorBounds(right - getResources().getDrawable(R.drawable.group_indicator_padding).getIntrinsicWidth(), right);

this code works fine up to 4.2.2 and do nothing on 4.3

Above answer will work for you. As setIndicatorBoundsRelative will work for Android >= 4.3 – AnkitRox Jan 09 '15 at 06:41
