            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ems="10"
            android:maxLength="2"
            android:inputType="textCapCharacters"
            android:hint="Country (two letter ISO code)"
            android:textAppearance="@android:style/TextAppearance.Small" />

Answer 1

EditText edt =(EditText)findViewById(R.id.edt); 

edt.setFilters(new InputFilter[]{
                   filter,
                   new InputFilter.LengthFilter(2)
               }); 

Answer 2

EditText editText = new EditText(this);  
int maxLength = 3;    
editText.setFilters(new InputFilter[] {new InputFilter.LengthFilter(maxLength)});
