java - 如何在 TextInputLayout 中设置错误结束图标。错误发生时显示，没有错误时消失

Question

我想在 TextinputLayout 中设置错误结束图标，以显示何时发生错误。我该怎么办？

Emailtext.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void onTextChanged(CharSequence charSequence, int start, int before, int count) {
                if(charSequence.length()<5)
                {
                  EmailLayout.setError("Error is occur");
                  EmailLayout.setEndIconDrawable(R.drawable.baseline_info_black_48);
                  EmailLayout.setEndIconActivated(true);
                  EmailLayout.setEndIconContentDescription("Error icon");

                }
                else
                {

                    EmailLayout.setErrorEnabled(false);
                }

            }

在你的其他情况下，

EmailLayout.setError(null);
