I want to remove the blue line from edittext when I touch edittext, but I do not know how to remove it. see image for more understanding
do it like that
lUserNameEditText.clearFocus();
another way that works for me regarding the border,
lUserNameEditText.setBackgroundColor(0);
You tried to change Layout XMLas follows
Layout XML
<EditText android:layout_width="fill_parent" android:layout_height="wrap_content" android:hint="Password" android:background="#00000000" />
or do it with code
editTextView.setBackgroundColor(0);
remove requestFocus tag in xml layout to automatically focus on losses
