我无法在6.0以下的任何版本的android中设置TextView颜色

Question

I am using the android support library. In my XML if I use TextView the text color will not change in any version of android other than android 6.0. I have the problem on multiple screen layouts.

    <TextView
        android:id="@+id/tvStatus"
        android:textColor="#FFFFFF00"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:text="@string/ted240" />

If I use android.widget.TextView everything works as it should on older version of android.

    <android.widget.TextView
        android:id="@+id/tvStatus"
        android:textColor="#FFFFFF00"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:text="@string/ted240" />

I updated the support library and gradle recently. I'm not sure if that caused the problem. If I try changing them back I still have the same problem.

use below six digit hexa number only not 8

  <TextView

       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:textColor="#ff0000"
   />

From Android Support Library 23, a new getColor() method has been added to ContextCompat.

But you can use it like below method which I use,

public static int getColorWrapper(Context context, int id) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        return context.getColor(id);
    } else {
        //noinspection deprecation
        return context.getResources().getColor(id);
    }
}

Then You need to call like below,

 textView.setTextColor(getColorWrapper(context,R.color.black));

Hope this will work for you.

I tried to clean and then rebuild the project and nothing seemed to fix it. I tried changing it all the way back to 'com.android.support:appcompat-v7:22'.

I seem to have fixed it by changing to

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

and then once it started working again I changed to

compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.android.support:design:23.2.0'

and everything seems fine. I am confused but happy it works.
