Here I have written a detailed article on the topic, as we have several options, Capitalize First Letter of String in Android

Method to Capitalize First Letter of String in Java

public static String capitalizeString(String str) {
        String retStr = str;
        try { // We can face index out of bound exception if the string is null
            retStr = str.substring(0, 1).toUpperCase() + str.substring(1);
        }catch (Exception e){}
        return retStr;
}

Method to Capitalize First Letter of String in Kotlin

fun capitalizeString(str: String): String {
        var retStr = str
        try { // We can face index out of bound exception if the string is null
            retStr = str.substring(0, 1).toUpperCase() + str.substring(1)
        } catch (e: Exception) {
        }
        return retStr
}

Using XML Attribute

Or you can set this attribute in TextView or EditText in XML

android:inputType="textCapSentences"

Please create a custom TextView and use it    public class CustomTextView extends TextView        public CapitalizedTextView Context context  AttributeSet attrs            super context  attrs               Override     public void setText CharSequence text  BufferType type            if  text length    gt  0                text   String valueOf text charAt 0   toUpperCase     text subSequence 1  text length                       super setText text  type

The accepted answer is good  but if you are using it to get values from a textView in android  it would be good to check if the string is empty  If the string is empty it would throw an exception   private String capitizeString String name       String captilizedString         if  name trim   equals              captilizedString   name substring 0 1  toUpperCase     name substring 1             return captilizedString

I should be able to accomplish this through standard java string manipulation  nothing Android or TextView specific     Something like   String upperString   myString substring 0  1  toUpperCase     myString substring 1  toLowerCase      Although there are probably a million ways to accomplish this   See String documentation   EDITED I added the  toLowerCase

Following does not apply to TextView  but works with EditText  even then  it applies to the text entered from the keyboard  not the text loaded with setText    To be more specific  it turns the Caps on in the keyboard  and the user can override this at her will   android inputType  textCapSentences    or  TV sname setInputType InputType TYPE TEXT FLAG CAP SENTENCES       This will CAP the first letter   or  compile  org apache commons commons-lang3 3 4    in build gradle module app   tv setText StringUtils capitalize myString toLowerCase   trim
