Android text styling error - Resource is not a ColorStateList

问题:

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:

FATAL EXCEPTION: main java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.aaa/com.example.aaa.activity.MainActivity}: android.view.InflateException: Binary XML file line #17: Error inflating class TextView     at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2100)     at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2125)     at android.app.ActivityThread.access$600(ActivityThread.java:140)     at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1227)     at android.os.Handler.dispatchMessage(Handler.java:99)     at android.os.Looper.loop(Looper.java:137)     at android.app.ActivityThread.main(ActivityThread.java:4898)     at java.lang.reflect.Method.invokeNative(Native Method)     at java.lang.reflect.Method.invoke(Method.java:511)     at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1006)     at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:773)     at dalvik.system.NativeStart.main(Native Method) Caused by: android.view.InflateException: Binary XML file line #17: Error inflating class TextView     at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:704)     at android.view.LayoutInflater.rInflate(LayoutInflater.java:746)     at android.view.LayoutInflater.rInflate(LayoutInflater.java:749)     at android.view.LayoutInflater.inflate(LayoutInflater.java:489)     at android.view.LayoutInflater.inflate(LayoutInflater.java:396)     at android.view.LayoutInflater.inflate(LayoutInflater.java:352)     at android.support.v7.app.AppCompatDelegateImplV7.setContentView(AppCompatDelegateImplV7.java:249)     at android.support.v7.app.AppCompatActivity.setContentView(AppCompatActivity.java:106)     at com.example.aaa.activity.MainActivity.onCreate(MainActivity.java:54)     at android.app.Activity.performCreate(Activity.java:5206)     at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1083)     at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2064)     ... 11 more Caused by: android.content.res.Resources$NotFoundException: Resource is not a ColorStateList (color or path): TypedValue{t=0x1/d=0x7f0b0124 a=-1 r=0x7f0b0124}     at android.content.res.Resources.loadColorStateList(Resources.java:2068)     at android.content.res.TypedArray.getColorStateList(TypedArray.java:342)     at android.widget.TextView.<init>(TextView.java:896)     at android.support.v7.widget.AppCompatTextView.<init>(AppCompatTextView.java:44)     at android.support.v7.widget.AppCompatTextView.<init>(AppCompatTextView.java:40)     at android.support.v7.internal.app.AppCompatViewInflater.createView(AppCompatViewInflater.java:103)     at android.support.v7.app.AppCompatDelegateImplV7.createView(AppCompatDelegateImplV7.java:806)     at android.support.v7.app.AppCompatDelegateImplV7.onCreateView(AppCompatDelegateImplV7.java:836)     at android.support.v4.view.LayoutInflaterCompatHC$FactoryWrapperHC.onCreateView(LayoutInflaterCompatHC.java:44)     at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:675)     ... 22 more 

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!

回答1:

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.

回答2:

You probably meant to use:

style="@style/basic_text_color" 

回答3:

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

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

回答4:

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)));
