setTextAppearance()

Question

I'm trying to build an app and want to show error if someone didn't fill-up the form correctly. Can I change the style of each component in Android Studio using java to highlight the component.

What I've done so far is this:

1. in styles.xml file, I did declare a new style name errorstyle as following:

<style name="errorstyle" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:textColor">#f45c42</item>
</style>

2. secondly in java file I did try to use following code.

selectedDate.setTextAppearance(this, android.R.style.errorstyle);

And it gives me an error message in java file:

cannot resolve symbol 'errorstyle'

Any suggestions?

cannot resolve symbol 'errorstyle'

<style name="errorstyle" parent="Theme.AppCompat.Light.DarkActionBar">

Style errorstyle in your style section, So don't call android.R. Use R.style instead.

Do

selectedDate.setTextAppearance(R.style.errorstyle);

FYI

setTextAppearance(Context context, int resId)

This method was deprecated in API level 23.

Use setTextAppearance(int) instead.

You should use R.style.errorstyle instead of android.R.style.errorstyle. Resources in android.R.* are coming from Android, resources created by you is in R.*.

Use R.style.errorstyle instead of R.android.style.errorstyle. Sometimes it takes a while for Android Studio to recognize a style that you may have override. Try rebuilding the project or invalidate cache and restart android studio.
