I am using TextInputLayout from com.android.support:design:23.3.0
When I first apply an error it is shown correctly.
mInputPassword.setError(getString(R.string.error_invalid_password));
mInputEmail.setError(getString(R.string.error_field_required));
On the next login attempt I clear the error.
mInputEmail.setError(null);
mInputPassword.setError(null);
Then I run the validation and set the error again using the same code as above but this time the red line is applied but the error text is missing.
Anyone have any ideas on why this might be happening or have experienced similar situations?
I saw something similar reported here but it is for an older version of the design library and don't know if it is still a issue in the verison I am using,
You simply has to do these steps:
setErrorEnabled(true);
setError("error");
for clearing:
setError(null);
setErrorEnabled(false);
repeat the first step to set a new error. setError(null) clears the error message and icon, so I think the view to show is simply gone and setErrorEnabled(false) will reset it.
You are clearing the Error Message String:
mInputEmail.setError(null);
mInputPassword.setError(null);
So when you rerun the validation, you will get a blank string.
If you want the error message to go away, clear the erroneous text from the textview:
mInputEmail.setText("");
mInputPassword.setText("");

I am using basic TextInputLayout. I am setting error when EditText is empty. When user enters some text, I am removing error text like this.
tilPassword.isErrorEnabled = false
tilPassword.error = null
This is working fine and good. The reason for calling tilPassword.isErrorEnabled = false is that it is helping me to remove extra space that TextInputLayout adds to the layout when showing error texts. When user enters some text, I am removing error and also the extra space (that is added by TextInputLayout) as well.
Error message is being removed but extra space is not getting removed in Android 9.0. How to solve this issue?
https://developer.android.com/reference/com/google/android/material/textfield/TextInputLayout.html#setErrorEnabled(boolean)
The docs explain:
Enabling this functionality before setting an error message via setError(CharSequence), will mean that this layout will not change size when an error is displayed.
So it would work like so.
Show an error:
tilPassword.setErrorEnabled(true)
tilPassword.setError("Wrong password")
Hide an error:
tilPassword.setError("")
tilPassword.setErrorEnabled(false)
Ensure that you are using the AndroidX version of TextInputLayout:
https://developer.android.com/reference/com/google/android/material/textfield/TextInputLayout.html
As the platform version below is deprecated:
https://developer.android.com/reference/android/support/design/widget/TextInputLayout

Please help me to solve this issue?
Thanks in advance.
I have submited an issue last Friday. This is due to the last update and will be fixed on the next update (next Friday). You can workaround it by disabling the on top side menu for now with: yourForm.getToolbar().setOnTopSideMenu(false);
We can not analyse what went wrong, because error is a generic "Null Pointer Exception". We need to know complete functionality and what different behaviour happened. Please provide us with some more details if possible.
I have set error message by txt1.setError() but it's not working all time I mean
some time Error message is not completely showing . See both images.Give me suggestion.
txt1.setError(getString(R.string.error_card));
Not working
So I'm trying to complete Google's "My First App", and have gotten everything to work up to this point. However, I am receiving a false error on two of my brackets.
I am not allowed to post images for some reason, so here is a link to my screencap (which I thought appropriate as it highlighted all the errors): http://imgur.com/0BYjZ2X
I have cleaned the build, rebuilt the project, restarted my computer, completely wiped the code, and repeated in all manner of orders to no avail. Someone here experienced a similar problem on an older build of the ADT plugin: Syntax error on token "}", delete this token
Any help would be greatly appreciated, as three hours of my time and a lot of caffeine haven't made a dent in the problem.
Android SDK false syntax error “Syntax error on token ”}“
I think its not false syntax error. You need to put the sendMessage function inside the } quote at line 29, which is showing the error. Your function is outside the Activity. That is why it is giving the error since last 3 hours :).
From the screencap, your class ends on line 29, and the sendMessage method is outside the class. Put the sendMessage method inside the Activity.
Remove the "}" from line 29 and add it to the end of the code..:)
The class should end after send message function. All the code for the class should be within that class.
So move the } to the end of the file.
I am getting error with the generated java file. But the code is fine and good . Can any one give suggestion.
thanks in advance.
Based on your image it appears that you are getting an error with the element with id of "enter", try changing the id of that element to something more descriptive and the error might go away.
You don't say which error you are getting. Usually you can resolve errors in R.java by removing it, and letting Eclipse regenerate it. If you still are getting the same error, you can try to rename the controls with the offending id.
If you wish further assistance, you need to say which error you are getting.
