How To Change Expandablelistview Group Indicator Position?
I want to change the ExpandableListView group indicator to right with padding. I used custom adapter to load data to ExpandableListView. This is my ExpandableListView xml.
Solution 1:
setIndicatorBounds(int, int) does not work properly for Android 4.3. They introduced a new method setIndicatorBoundsRelative(int, int) which works ok for 4.3.
publicintGetPixelFromDips(float pixels) {
// Get the screen's density scale finalfloatscale= getResources().getDisplayMetrics().density;
// Convert the dps to pixels, based on density scalereturn (int) (pixels * scale + 0.5f);
}
@OverridepublicvoidonWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
DisplayMetricsmetrics=newDisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
intwidth= metrics.widthPixels;
if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.JELLY_BEAN_MR2) {
explvList.setIndicatorBounds(width-GetPixelFromDips(35), width-GetPixelFromDips(5));
} else {
explvList.setIndicatorBoundsRelative(width-GetPixelFromDips(35), width-GetPixelFromDips(5));
}
}
Solution 2:
privatevoidsetGroupIndicatorToRight() {
/* Get the screen width */DisplayMetricsdm=newDisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
intwidth= dm.widthPixels;
expandableList.setIndicatorBounds(width - getDipsFromPixel(35), width - getDipsFromPixel(5));
}
// Convert pixel to dippublicintgetDipsFromPixel(float pixels) {
// Get the screen's density scalefinalfloatscale= getResources().getDisplayMetrics().density;
// Convert the dps to pixels, based on density scalereturn (int) (pixels * scale + 250.5f);
}
Solution 3:
If you want to move indicator to right Just create a dimen in res folder. It will be like that:
<?xml version="1.0" encoding="utf-8"?><resources><dimenname="my_value">350dp</dimen></resources>Then in the <ExpandableListView/> add like that:
<ExpandableListView...android:indicatorLeft="@dimen/my_value".../>You can change the dp according to device settings
