Fragments are not switching smoothly - Slow change in login to signup fragment and vice-versa

[PalakJainAndroidDeveloper]

when i click on sign in textView on login fragment then Logcat is showing warning

W/IInputConnectionWrapper: finishComposingText on inactive InputConnection finishComposingText on inactive InputConnection

and the page is not switching. problem might be i use textUtils

 private Boolean  validate() {
        //for email validation
        Pattern pattern;
        Matcher matcher;
        final String EMAIL_PATTERN="^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";
        pattern=Pattern.compile(EMAIL_PATTERN);
        matcher=pattern.matcher(email_id.getText().toString());
        if (TextUtils.isEmpty(email_id.getText())) {
            email_id.setError("Please enter username");
            email_id.requestFocus();
        }else if (TextUtils.isEmpty(password.getText())) {
            password.setError("Please enter your password");
            password.requestFocus();
        }else if (TextUtils.isEmpty(confirmPassword.getText().toString())) {
            confirmPassword.setError("Please enter your password");
            confirmPassword.requestFocus();
        }else if(!password.getText().equals(confirmPassword.getText()) ){
            //Passward and confirm password is not same
            Toast.makeText(getContext(),"Confirm Password should be same as Password", Toast.LENGTH_SHORT).show();
        } else if(!matcher.matches()){
            //email is validate
            Toast.makeText(getContext(),"Please Enter a Valid Email address like example@gmail.com ", Toast.LENGTH_SHORT).show();
        } else{
            return true;
        }
        return false;
    }

on button click event. so please tell me what else i can do so that this error is removed and fragment will move smoothly . I am attaching signup fragment code with this question.
