Android text styling error - Resource is not a Col

Question

I have a very simple textview:

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
android:textSize="20sp"
android:textColor="@style/basic_text_color"
android:layout_gravity="center"
android:id="@+id/toolbar_title" />

Which @style/basic_text_color is a color that I wanted to reuse a lot of time in the app, so I make a app_colors.xml under values folder:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!--  Text colors style-->
    <style name="basic_text_color" parent="@android:style/TextAppearance">
         <item name="android:textColor">#ff932e</item>
    </style>

    <!-- some other color styles-->
</resources>

The app compile successfully, but then whenever it executed it will hang and following error would be prompted in LogCat:

So it looks like the the error here is "Resource is not a ColorStateList (color or path): TypedValue{t=0x1/d=0x7f0b0124 a=-1 r=0x7f0b0124}" ...

Did I styled the font color in a wrong way? Or any other things go wrong? Thanks!

Answer 1

You probably meant to use:

style="@style/basic_text_color"

Answer 2

If you want to set your color from Java, you could use something like this:

myView.setBackgroundTintList(ColorStateList.valueOf(getResources().getColor(R.color.grey_300)));

Answer 3

colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="basic_text_color">#ff932e</color> 
</resources>

layout

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/app_name"
    android:textSize="20sp"
    android:textColor="@colors/basic_text_color"
    android:layout_gravity="center"
    android:id="@+id/toolbar_title" />

You have to create a color resource file if you want to change the textColor, as it was in your question you are trying to set as color a style.

Answer 4

You should use the color attribute instead of the style one as.

<color name="basic_text_color">#YOUR COLOR GOES HERE</color>
