setError for TextInputLayout showing Error

Question

TextInputLayout working fine, when tried to set Error it showing error.

Code:

 if (etFirstName.getText().length() == 0) {
            etFirstName.requestFocus();
            tvFirstName.setError("Please enter firstname");
        } else {
            tvFirstName.setError(null);
            tvFirstName.setErrorEnabled(false);
        }

Check Log:

java.lang.RuntimeException: Failed to resolve attribute at index 24

Solution 1

Give valid style for your TextInputLayout( android:theme="@style/Theme.AppCompat")

<android.support.design.widget.TextInputLayout
  android:id="@+id/testingInputLayout"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:theme="@style/Theme.AppCompat">

<EditText
   android:id="@+id/testingEditText"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:hint="@string/testText"
   android:inputType="textEmailAddress" />

</android.support.design.widget.TextInputLayout>

You need to add appCompat & support design dependency (if not)

compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'

In your manifest file add AppCompat theme,

<application
 ...
android:theme="@style/Theme.AppCompat">

Solution 2

Although I did not fully understand why the problem occurs, it must have to do something about how Android applies colors to Views according to its states.

Here is the way I solved the problem:

1) Define custom style, that will be used only for styling the errors (or hints) only:

In your res/values/styles.xml add new style node:

    <style name="error" parent="@android:style/TextAppearance">
        <item name="android:textColor">@color/colorAccent</item> <!--apply the color you wat here -->
        <item name="android:textSize">12dp</item>
    </style>

2) Apply the style to your TextInputLayout:

Also, make sure, that you specify errorEnabled attribute:

<android.support.design.widget.TextInputLayout
        android:id="@+id/input_email_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="8dp"
        app:errorEnabled="true"
        app:errorTextAppearance="@style/error"
    >
        <android.support.design.widget.TextInputEditText
            android:id="@+id/input_email"
                  android:layout_width="match_parent"
                  android:layout_height="wrap_content"
                  android:inputType="textEmailAddress"
                  android:hint="@string/hint_email"/>
    </android.support.design.widget.TextInputLayout>

setError don't work for textview. It works with editext only. To do it for textview follow this link stackoverflow.com/questions/13508270/…

If you need customize theme -> use the parent theme as Theme.AppCompat & write your customize theme.

How this solve a problem? the editText.getText() has @NonNull which means that there is no need to check it for null, original code is valid!

This should be accepted answer. Only these steps worked for me.
