android - What is the point of SharedPreferences.getFloat() -

the method getfloat() exists pull float value android's sharedpreferences api. yet, in xml, edittextpreference stores string value, if numeric defined.

one expect getfloat() automatically homecoming instead throws classcastexception , have utilize float.parsefloat(sharedpreferences.getstring()) value.

is there literally no utilize getfloat() or missing here?

yes.

yet, in xml, edittextpreference stores string value, if numeric defined.

i think mixing things here. setting sharedpreferences equal elements on preferencescreen.

preferencescreen's save values sharedpreferences , it's true edittextpreferences can't save float, can save float sharedpreferences yourself:

sharedpreferences prefs = getsharedpreferences(prefs_name, 0); sharedpreferences.editor editor = prefs.edit(); editor.putfloat("afloat", 1.2f); editor.commit();

and retrieve float this:

float somefloat = prefs.getfloat("afloat", 0.0f);
