android - Textview width doens't adjust after change content -

i'm trying update content of textview data introduced edittext. after change text, if original text (hint) bigger new text, width doens't change.

i have next string in hint attribute of textview, "please, introduce amount". if put 25'5, example, textview doesn't resize width.

first screen

second screen

the euro symbol invisible behind textview, , it's shown after insert value.

the piece of code amount:

you seem want change width of tvimportedesc dynamically. short of android not allow this, though people have developed work arounds. (toggling visibility answers suggest did not work me). similar questions:

change relative layout width , height dynamically

wrap_content not working after dynamically adding views

since trying fit text on same line might easier use single textview line of text, , concatenate euro symbol?
