Android：使用主题/样式更改禁用文本的颜色？ [英] Android: change color of disabled text using Theme/Style?

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));
    }
}
