问题描述
我在color.xml中定义了以下颜色:
I have the following colors defined in my color.xml:
<color name="gold">#d49e43</color>
<color name="gold_disabled">#80d49e43</color>
和以下主题:
<style name="Theme.Example" parent="@style/Theme.Sherlock">
<item name="android:textColor">@color/gold</item>
</style>
在我的SettingsActivity中,我有一个CheckBoxPreference和一个取决于它的Preference。当CheckBoxPreference未被选中时,首选项被禁用,但是,由于我设置的自定义金色文本颜色,它不会像默认颜色一样灰色。如何在XML中更改此?我尝试设置:
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>
但没有任何效果。
推荐答案
我偶然想出来了,但如果你的子类化Preference并覆盖onBindView(),你可以实现灰色的效果,当首选项被禁用:
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));
}
}
