如何更改CheckBoxPreference中标题文本的颜色?
正如zenob所说,这可以通过自定义布局来解决。在应用程序中使用了框架中定义的Preference布局:
custom_preferece_layout.xml
<?xml version="1.0" encoding="utf-8"?>

<!-- Layout for a Preference in a PreferenceActivity. The Preference is able
to place a specific widget for its particular type in the "widget_frame"
layout. -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeight"
android:gravity="center_vertical" android:paddingRight="?android:attr/scrollbarSize">
<RelativeLayout android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_marginLeft="15dip"
android:layout_marginRight="6dip" android:layout_marginTop="6dip"
android:layout_marginBottom="6dip" android:layout_weight="1">
<TextView android:id="@+android:id/title"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:singleLine="true" android:textAppearance="?android:attr/textAppearanceLarge"
android:ellipsize="marquee" android:fadingEdge="horizontal"
android:textColor="#FF0000" />
<TextView android:id="@+android:id/summary"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_below="@android:id/title" android:layout_alignLeft="@android:id/title"
android:textAppearance="?android:attr/textAppearanceSmall"
android:maxLines="4" />
</RelativeLayout>
<!-- Preference should place its actual preference widget here. -->
<LinearLayout android:id="@+android:id/widget_frame"
android:layout_width="wrap_content" android:layout_height="match_parent"
android:gravity="center_vertical" android:orientation="vertical" />
</LinearLayout>
上述布局中,标题TextView定义了textColor属性。将此布局与偏好设置XML中的复选框偏好设置一起使用。
mypreference.xml
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<CheckBoxPreference android:key="testcheckbox"
android:title="Checkbox Title"
android:summary="Checkbox Summary..."
android:layout="@layout/custom_preference_layout"></CheckBoxPreference>
</PreferenceScreen>
< p > 复选框偏好设置的标题将具有在自定义布局中定义的颜色。< /p >
<item name="android:textColorSecondary">#000000</item>
<item name="android:textColorPrimary">#000000</item>
textColorPrimary
将改变 checkBoxPreference
标题的颜色,textColorSecondary
将改变 summary
的颜色。
很遗憾,您无法访问CheckBoxPreference布局 - 它在内部包中声明。
您仍然可以创建具有自定义布局的自己的首选项。
