Android: change color of disabled text using Theme/Style?
android, colors, styles, textview, themes
Solution
I figured this out more or less by accident, but if you subclass Preference and override the onBindView(), you can achieve the "grayed out" effect when a preference is disabled:
@Override
protected void onBindView(View view) {
// TODO Auto-generated method stub
super.onBindView(view);
TextView title = (TextView)view.findViewById(android.R.id.title);
TextView summary = (TextView)view.findViewById(android.R.id.summary);
if (title.isEnabled()) {
title.setTextColor(getContext().getResources().getColor(R.color.gold));
}
else {
title.setTextColor(getContext().getResources().getColor(R.color.gold_disabled));
}
if (summary.isEnabled()) {
summary.setTextColor(getContext().getResources().getColor(R.color.orange));
}
else {
summary.setTextColor(getContext().getResources().getColor(R.color.orange_disabled));
}
}
Problem
I have the following colors defined in my color.xml: ``` <color name="gold">#d49e43</color> <color name="gold_disabled">#80d49e43</color> ``` And the following theme: ``` <style name="Theme.Example" parent="@style/Theme.Sherlock"> <item name="android:textColor">@color/gold</item> </style> ``` In my SettingsActivity, I have a CheckBoxPreference and a Preference that depends on it. When The CheckBoxPreference is unchecked, the Preference is disabled, however, because of the custom gold text color that I set, it doesn't get "greyed out" like it does with the default color. How do I change this in XML? I've tried setting: ``` <item name="android:textColorPrimaryDisableOnly">@color/gold_disabled</item> <item name="android:textColorPrimaryInverseDisableOnly">@color/gold_disabled</item> <item name="android:textColorPrimaryNoDisable">@color/gold_disabled</item> <item name="android:textColorSecondaryNoDisable">@color/gold_disabled</item> <item name="android:textColorPrimaryInverseNoDisable">@color/gold_disabled</item> <item name="android:textColorSecondaryInverseNoDisable">@color/gold_disabled</item> ``` but nothing seems to work.
